Embodiment 1

First, an embodiment of the present invention, a fresh-keeping device and a space potential generating device equipped with the fresh-keeping device, will be described.

＜Fresh-keeping device＞

First, the fresh-keeping apparatus of this Embodiment 1 is demonstrated. The fresh-keeping device of the first embodiment is a device that forms an alternating electric field in a space for fresh-keeping fresh products, and keeps fresh-keeping products in the fresh-keeping space where the alternating electric field is formed. In addition, the fresh-keeping device of the first embodiment is provided with a space potential generating device that forms an alternating electric field.

FIG. 1 is a cross-sectional view schematically showing an example of the fresh-keeping device according to the first embodiment. 2 is a plan view schematically showing an example of an electrode unit provided in the fresh-keeping device according to Embodiment 1. FIG.

The fresh-keeping device of the present embodiment 1 is installed on a refrigerator including an ordinary household refrigerator as a delimiting part for delimiting the fresh-keeping space. This case will be described below. However, in the first modification and the third modification of the first embodiment to be discussed later, as described with reference to FIGS. 10 to 12 , the freshness preservation device of the first embodiment is defined as a demarcation part of the fresh space. , can also be installed in the demarcation part other than household refrigerators. Alternatively, in the fourth modification of Embodiment 1 to be discussed later, as illustrated in FIG. 13 , the fresh-keeping device of Embodiment 1 may not be provided with a demarcation portion that delimits the fresh-keeping space.

As shown in FIG. 1 , the fresh-keeping device according to the first embodiment includes a refrigerator 1 , an electrode part 2 , and a voltage applying device 3 . The refrigerator 1 includes a delimited fresh-keeping space 5 , and the space delimited by the fresh-keeping space 5 is used for fresh-keeping of the fresh products 4 , and the fresh-keeping space 5 is included in the refrigerator 1 . The refrigerator 1 can be referred to as a common household refrigerator as described above. The electrode portion 2 is installed in the fresh-keeping space 5 delimited by the demarcation portion. In other words, the electrode part 2 is installed in the refrigerator 1 . The voltage applying device 3 is built in the rear surface of the refrigerator 1 , and an alternating electric field is formed around the electrode portion 2 by applying an AC voltage VL1 (refer to FIG. 3 below) to the electrode portion 2 . The electrode portion 2 and the voltage applying means 3 constitute an electric field generating means for forming an alternating electric field, that is, a space potential generating means. At the same time, the electrode part 2 is also an electrostatic discharge part that discharges static electricity in the fresh-keeping space 5 . That is, the electrode part 2 is an electrostatic discharge part including all of the empty potential generating device 6 .

In the fresh-keeping device of the first embodiment, static electricity is discharged into the fresh-keeping space 5 through the electrode portion 2 , and an alternating electric field is formed in the fresh-keeping space 5 , that is, around the electrode portion 2 , and the formed alternating electric field is applied to the fresh product 4 . , the fresh product 4 is kept fresh. At this time, under the influence of the alternating electric field, the water molecules in the fresh product 4 are irradiated by electromagnetic waves of a specific frequency, and the cells are activated, so that the fresh product 4 can be kept fresh for a long time.

Moreover, the fresh products in the specification of this application include vegetables, fruits, flowers and other crops, such as agricultural and livestock products such as meat, and aquatic products such as fish and shellfish.

As shown in FIG. 1, the space inside the refrigerator 1, that is, the fresh-keeping space 5, is divided into three spaces by the partition plate 11 and the partition plate 12, which are the uppermost low-temperature fresh-keeping chamber 13, the middle layer of the refrigerating chamber 14, And the vegetable room 15 on the lowest floor. Thus, in the example of FIG. 1 , the low-temperature fresh-keeping compartment 13 , the refrigerator compartment 14 , and the vegetable compartment 15 collectively constitute the fresh-keeping space 5 .

Inside the partition plate 11 between the low-temperature fresh-keeping compartment 13 and the refrigerating compartment 14, an electrostatic discharge part including the space potential device 6, that is, the electrode part 2 is provided. In this case, the separator 11 also serves as an insulating member, and covers the surface of the electrode portion 2 to perform an insulating function. In this way, the electrode portion 2 is installed inside the partition plate 11, the electrode portion 2 cannot be seen from the outside, and the appearance is more secure. The user will not directly contact the electrode part 2, so it can effectively prevent the user from directly contacting the electrode and causing electric shock.

In addition, since the electrode part 2 is installed inside the partition plate 11 , the intensity of the alternating electric field in the low-temperature fresh-keeping compartment 13 and the refrigerating compartment 14 near the electrode part 2 becomes stronger, and the vegetable compartment farther from the electrode part 2 becomes stronger. The alternating electric field inside 15 will be weak, and thus, an alternating electric field with a required strength suitable for the fresh food 4 stored therein can be obtained.

However, in FIG. 1 , although the electrode part 2 is installed inside the separator 11 , the installation position of the electrode part 2 is not limited to the place illustrated in FIG. 1 . That is, the electrode plate 2 can be installed anywhere, such as the inside of the back plate, the top plate, or other partition plates of the refrigerator 1 .

In the example shown in FIG. 1 , the electrode portion 2 is formed of a plate-shaped conductive material. In addition, the electrode portion 2 may be flat or curved.

As shown in FIG. 2 , it is preferable that the electrode portion 2 is provided with a plate-shaped portion 22 including the main surface 21 . Thereby, the electrode part 2 can also be easily attached to the inside of the separator 11 .

As shown in FIG. 2 , it is more suitable that the plate-like portion 22 is constituted by the main surface 21 and has a plurality of recessed portions or holes, that is, a plurality of opening portions 23 . The shape of the opening portion 23 may be set to be circular or hexagonal when viewed from a perspective perpendicular to the main surface 21 of the plate-like portion 22 . Because the plate-shaped portion 22 has such a circular or hexagonal opening 23 , the alternating electric field is concentrated at the edge of the opening 23 , and static electricity is more easily discharged from the electrode portion 2 to the surrounding of the fresh product 4 . However, the electrode portion 2 does not necessarily have to have the plate-like portion 22 . For example, a board laminated with aluminum foil can also be used as a discharge board for the electrode portion 2 . In addition, if only high-voltage wires are used, and it is made into a plate shape with a waterproof effect, this plate can also be used as a discharge plate for the electrode portion 2, that is, an output discharge plate for outputting alternating current, and the same effect can be obtained. Not limited to the electrical conductivity of aluminum, copper, steel, iron, carbon, etc., various materials can be used when connecting to the output unit.

Using a plate-shaped output plate as the electrode part 2 improves the waterproof performance of the electrode part 2 , makes it easier to reduce the weight of the electrode part 2 , makes the electrode part 2 easier to install, and helps to reduce the thickness of the electrode part 2 .

The output plate can be made from aluminum as described above, or can be machined from carbon. The output plate made of carbon can be used, for example, in a size of 25cm x 25cm x 1mm thick. For example, the output plate made of carbon processing method has a weight of 80 grams, and it is easier to reduce the weight of the electrode part 2 and to install it more easily than the output plate of other materials.

In addition, the output plate made of carbon processing reduces the resistance of the electrode part 2 and strengthens the electrical conductivity of the electrode part 2, so that the effect and effective range of the alternating electric field are increased to twice that of the output plate made of other materials. Specifically, the output plate made of carbon can reduce the resistance to 5-40Ω. For example, the output plate made of aluminum, the effect of the alternating electric field at a position 3 meters away from it, is made of carbon. The resulting output plate can form an alternating electric field with the same intensity at a distance of 5 meters.

In addition, a ceramic powder that easily emits far infrared rays can be added to the output plate made of carbon. For example, tourmaline may be used for the ceramic, and the particle size of the powder may be 200 μm. Far-infrared ceramics such as tourmaline are prone to generate negative ions, which can further increase the effect and effective range of the alternating electric field. In addition, a photocatalyst such as titanium oxide or an oxygen catalyst can also be coated on the output plate made of carbon to further enhance the preservation effect.

In addition, the electrode part 2 may not be installed in the partition plate, but may be installed inside the low temperature fresh-keeping compartment 13 , the refrigerating compartment 14 , or the vegetable compartment 15 . In this case, and the plate-shaped portion 22 has the circular or hexagonal opening portion 23 on the upper surface, when the fan installed in the refrigerator 1 circulates the air in the refrigerator 1, the electrode portion 2 will not hinder the air circulation. Therefore, the fresh-keeping conditions including the electric field intensity in the low-temperature fresh-keeping chamber 13 , the refrigerating chamber 14 and the vegetable chamber 15 can be easily uniformized.

In addition, an insulating portion may be provided on the main surface 21 of the plate-shaped portion 22 of the electrode portion 2 or on the back surface of the main surface 21 . Alternatively, the surface of the plate-like portion 22 may be covered with an insulating portion. Alternatively, the fresh-keeping device uses an insulating portion covering the surface of the electrode portion 2 . This will look more reassuring than the state where the plate-shaped portion 22 is leaking outside. Even if a problem occurs and a strong current flows through the secondary coil, there will be no electric shock, and the occurrence of corona discharge can also be prevented.

The surface of the insulating portion may have the same concave portion or hole as the opening portion 23, that is, the opening portion, and the surface of the insulating portion may be flat, but does not include the opening portion. In this case, the plate-like portion 22 should have a waterproof effect of preventing the electrode portion 2 from coming into contact with water. In addition, the surface of the flat insulating part may be coated with a photocatalyst such as titanium oxide or an oxygen catalyst. If there is a flat surface and there is an insulating part coated with a photocatalyst, the ethylene produced by the fresh products 4 in the fresh-keeping space 5 can be removed from the low-temperature fresh-keeping compartment 13 , the refrigerating compartment 14 , and the vegetable compartment 15 . In addition, since the photocatalyst or oxygen catalyst can be applied to the surface of the electrode portion 2 to be effective, it is also effective to apply the above-mentioned substance to the surface layer of the electrode instead of the surface of the insulating portion.

In addition, the output control unit 33 applies low frequency vibration to the output voltage of the secondary coil 36 . In other words, the output control unit 33 applies low-frequency vibration to the output voltage of the secondary coil 36 by connecting the other terminal 36 b of the secondary coil 36 .

The electrode portion 2 is connected to the AND output terminal 34 of the secondary coil 36 of the output control portion 33 , that is, to the other terminal 36 b side of the secondary coil 36 of the output control unit 33 via a power supply line 24 (see FIG. 1 ) formed of a conductive wire terminals on the opposite side. Therefore, the electrode portion 2 is connected to the other terminal 36 b of the secondary coil 36 via the power supply line 24 and the output control portion 33 .

According to the above-described voltage applying device 3, the current generated on the secondary coil 36 side by the feedback control circuit 32 is fed back to the primary coil 35, and the secondary coil 36 can obtain a high voltage with a small number of turns. In addition, the feedback control circuit 32 and the output control section 33 are configured to cause a delay in the circuit, and therefore, a low frequency vibration of, for example, 20 to 100 Hz can be applied to the secondary coil 36 .

Further, the feedback control circuit 32 connects one terminal 36a of the secondary coil 36 to one terminal 35a of the primary coil 35 to adjust the voltage at the secondary coil 36, as a result, miniaturization of the voltage applying device 3 can be achieved.

As described above, the fresh-keeping device of the first embodiment forms an alternating electric field in the fresh-keeping space 5 for maintaining the freshness of the fresh food 4, and keeps the fresh-keeping product 4 fresh in the fresh-keeping space 5 where the alternating electric field is formed. Specifically, static electricity is discharged from the electrode portion 2 into the fresh-keeping space 5 , an alternating electric field is formed in the fresh-keeping space 5 , and the formed alternating electric field is applied to the fresh product 4 to keep the fresh product 4 fresh.

At this time, due to the effect of the alternating electric field, the water molecules in the fresh product 4 are irradiated with electromagnetic waves of a specific frequency, which activates the cells. In addition, when the fresh product 4 is spoiled, by supplementing the electrons of the fresh product 4 which are reduced due to oxidation, the oxidation of the fresh product 4 is prevented and the activity of bacteria is inhibited. That is, the fresh-keeping device of the first embodiment is equipped with a space potential generating device 6, and by applying the influence of an alternating electric field, the fresh-keeping product 4 can be kept fresh for a long time.

In addition, the aggregation effect and the positive and negative electron charging effect are applied to the cells and the like in the fresh product 4, thereby suppressing cell oxidation. Moreover, the fresh food 4 can be sterilized and disinfected to inhibit the reproduction of bacteria.

When an alternating electric field is applied, chicken will not freeze up to -5°C, and beef, pork and fish will not freeze up to -7°C, so fresh products can be stored at low temperature without freezing. Therefore, when thawing frozen items, there is no need to worry about tissue damage, and long-term freshness without freezing can be achieved.

In addition, the fresh-keeping device according to the first embodiment includes a refrigerator 1 including a general household refrigerator, an electrode part 2 and a voltage applying device 3 . Also, as described above, due to the effect of the alternating electric field, long-term preservation of the fresh product 4 can be achieved. Therefore, the fresh-keeping device of the first embodiment can reduce the cost of introducing and operating the fresh-keeping device, and the alternating electric field formed by the space potential generating device can improve the fresh-keeping effect of the fresh product 4 .

On the other hand, the fresh-keeping device of Embodiment 1 generates high voltage at the output of the secondary coil 36 and low-frequency vibration at the output of the secondary coil 36 by the effects of the feedback control circuit 32 and the output control unit 33 . Therefore, even if the output of the terminal 36b has only one line, the electrode part 2 can discharge static electricity well from the electrode unit part 2 to the low-potential part (for example, the ground part), and can discharge static electricity around the electrode part 2 (specifically, the electrode part 2 ). 2 Within 360° within a radius of about 1.5 meters), a high-voltage alternating current electric field is formed. Therefore, an AC electric field can be formed around the fresh product 4 without using two electrodes. Thereby, the simplification of the structure of the fresh-keeping device can be achieved.

That is, in the fresh-keeping device of the first embodiment, if the electrode portion 2 is referred to as a first electrode, the voltage applying device 3 does not need to be electrically connected to any electrode other than the first electrode, nor does it need to apply a voltage to any electrode other than the first electrode. Therefore, the fresh-keeping effect of the fresh product 4 can be improved, and at the same time, the structure of the fresh-keeping equipment can be simplified.

When the refrigerator is divided into multiple spaces such as a refrigerator compartment, a vegetable compartment and a freezer compartment, if an alternating electric field is to be formed in the refrigerator, if it is a conventional space potential generating device, electrode plates need to be installed in each space, or two an electrode.

In addition, in the fresh-keeping device of the first embodiment, the electrode portion 2 functions as an antenna, and in the fresh-keeping space 5, even at a position with a certain distance from the electrode portion 2, the amplitude of the AC electric field applied in the space, that is, the voltage does not change. will be too small. Therefore, through the electrode part 2, only one electrode is provided to exert the aggregation effect and the positive and negative electron charging effect on the cells in the fresh food 4, thereby inhibiting the oxidation of cells, and can sterilize the fresh food 4 and inhibit the reproduction of bacteria. .

However, the intensity of the alternating electric field formed in the fresh-keeping space 5 is stronger as it is closer to the electrode portion 2, and vice versa. Therefore, depending on the type of fresh food 4 to be preserved, there are cases in which only a weak electric field is required for preservation and in cases in which a strong electric field is required. By appropriately adjusting the electrode portion 2 and the low-temperature fresh-keeping compartment 13, the refrigerator compartment 14 and the vegetable compartment The relative position of 15 to achieve the best effect.

The AC voltage VL2 is preferably applied to the primary coil 35 by an AC power source. Specifically, the voltage applying device 3 applies the AC voltage input from the AC power source to the primary coil 35 as the AC voltage VL2.

Alternatively, a battery may be used as the power source of the voltage applying device 3 . Even in this case, since the power consumption of the voltage applying device 3 is low, it can operate for three days in a state where, for example, 16 first-size batteries are connected in parallel. Therefore, the space potential generating device 6 can also be applied to movable equipment such as automobiles.

The output control unit 33 preferably applies a voltage having a frequency of 20 Hz to 100 Hz to the output of the secondary coil 36 . In other words, the voltage applying device 3 applies an AC voltage having a frequency of 20 Hz to 100 Hz to the electrode portion 2 . When the voltage applied by the output control unit 33 to the output of the secondary coil 36 is 20 Hz to 100 Hz, compared with the case where the voltage applied by the output control unit 33 to the output of the secondary coil 36 is lower than 20 Hz or higher than 100 Hz, It can effectively activate water molecules contained in cells and the like in the fresh food 4, or effectively prevent the oxidation of cells and the like in the fresh food 4, or sterilize the fresh food 4, thereby inhibiting the reproduction of bacteria.

Preferably the space potential generating means 6 are not connected to the ground stage. In other words, the fresh-keeping device is not connected to the ground level. Thereby, static electricity is easily discharged from the electrode portion 2 provided (connected) to the other-side terminal 36b of the secondary coil 36 .

The current flowing into the secondary coil 36 is preferably 0.002A to 0.2A. When the current flowing into the secondary coil 36 is 0.002A or more, compared with the case where the current flowing into the secondary coil 36 is less than 0.002A, the water molecules contained in the cells and the like in the fresh food can be more effectively activated, or The oxidation of cells and the like in the fresh product 4 is effectively prevented, or the activity of bacteria and the like in the fresh product 4 is effectively suppressed. In addition, when the current flowing into the secondary coil 36 is less than 0.2A, compared with the case where the current flowing into the secondary coil 36 exceeds 0.2A, since the current flowing into the secondary coil 36 is a weaker current, there is no fear of electric shock.

According to the space potential generation device 6 of the first embodiment, it can be used in a freezer, a refrigerator, a thawing room, a display case, a food storage room, an ISO (International Organization for Standardization) container, a transport truck, a room temperature warehouse, a refrigerator in a fishing boat, a medical In any place such as a refrigerator or a medical freezer, if only one electrode part 2 is installed, a high-voltage alternating electric field is formed in the space where the electrode part 2 is installed (in a warehouse, indoors, and in a vehicle). In this way, the fresh-keeping function utilizing the alternating electric field can be added to the application site at low cost and simply where necessary.

In addition, in the production of freezers, refrigerators, thawing rooms, display cases, food storage rooms, ISO containers, or normal temperature warehouses, by installing the electrode part 2 inside the walls, ceilings or partitions, it is possible to The freezer, cold storage, thawing storage, display cabinet, food storage room, ISO container or normal temperature warehouse have the fresh-keeping function from the beginning. In this case, if the electrode part 2 is built in the wall, ceiling, or the inside of the partition plate, the appearance can be improved, and the safety of the electrode part 2 can be improved compared with exposing the electrode part 2 to the outside. In addition, walls, ceilings or partitions will act as insulation, so there is no need to use special insulation materials, and there will be no risk of electric shock even if a strong current flows accidentally.

Large warehouses will be equipped with multiple shelves with a length of more than 8 meters. In order to make it easier to take out the pallets or forklifts on the shelves when shipping from the shelves, the shelves are usually designed to be movable left and right. In this case, the electrode part 2 and the shelf plate are separated, and the electrode part 2 can be easily mounted even in a movable shelf.

<Voltage adjustment section>

The voltage applying device 3 mounted on the space potential generating device 6 of the first embodiment further includes a voltage adjusting unit 41 . The voltage regulator 41 converts the voltage value of the AC voltage VL3 input from the AC power source into a plurality of voltage values different from each other, and applies the AC voltage VL3 whose voltage values are converted to the primary coil 35 as the AC voltage VL2, thereby adjusting the voltage value. The voltage value of the AC voltage VL1 output to the output terminal 34 .

Thereby, the voltage value of the AC voltage VL1 can be converted into, for example, two types of voltage values, strong and weak, or, for example, three types of voltage values, such as strong, medium, and weak. Therefore, in the fresh-keeping space 5, the intensity of the alternating electric field formed by the space potential generating device 6 can be adjusted and set according to the type, quantity or packaging condition of the fresh-keeping products 4, or the temperature or humidity of the fresh-keeping space 5. Certainly. As a result, the initial investment cost and long-term operation cost of the fresh-keeping device will be reduced, and at the same time, the effect of the alternating electric field formed by the space potential generating device will be better, or the influence range and the intensity of the object space can be better controlled. size.

The voltage adjustment unit 41 preferably includes a resistance element 42 and a switching element 43 . The resistance element 42 is provided between the terminal 35a on one side of the primary coil 35 or the terminal 35c serving as the terminal 35b on the other side and the AC input socket 37 which is an AC power source. In the example shown in FIG. 3 , the other terminal 35b of the primary coil 35 is the terminal 35c, but the one terminal 35a of the primary coil 35 may be the terminal 35c.

The switching element 43 is used to switch whether the terminal 35c is connected to the AC input socket 37 , which is an AC power source, via the resistor element 42 , or directly connected to the AC power source, ie, the AC input socket 37 , without the resistor element 42 . Thereby, the voltage value of the AC voltage VL2 applied to the primary coil 35 can be switched between the voltage value of the AC voltage VL3 input from the AC power source and a voltage value smaller than the voltage value of the AC voltage VL3, so that the voltage value of the AC voltage VL2 applied to the primary coil 35 can be easily changed. The voltage value of the AC voltage VL1 output to the output terminal 34 is switched between two different voltage values, strong and weak.

In addition, as the resistance element 42 , a variable resistor whose resistance value can be changed within a range of, for example, about 50Ω as a center value can be used. Thereby, the voltage value of the AC voltage VL2 applied to the primary coil 35 can be further changed when the voltage value is switched to a voltage value smaller than the voltage value of the AC voltage VL3, and the AC voltage output to the output terminal 34 can be further changed when the When the voltage value of the voltage VL1 is easily switched to two different voltage values, it can be easily changed to a smaller voltage value.

Further, as shown in FIG. 3 , the voltage adjustment unit 41 may further include a surge absorber 44 connected in parallel with the resistance element 42 . In this case, the switching element 43 is used to switch whether the terminal 35c is connected to the AC input socket 37 which is an AC power source via the resistance element 42 and the surge absorber 44 connected in parallel with each other, or not via the resistance element 42 and the surge absorber 44 connected in parallel with each other. The surge absorber 44 directly connects the terminal 35c to the AC input socket 37 which is an AC power source. Thereby, when a large voltage is suddenly applied to the resistance element 42 due to, for example, lightning, the resistance value of the surge absorber 44 decreases sharply, and the current flows to the surge absorber 44 in a concentrated manner, so that the current flowing to the resistance element 42 can be reduced. Thereby, the resistance element 42 can be prevented from burning out or the like.

The temperature in the storage room was 10 to 30°C, and the storage period was from the day the experiment started as the first day to the eighth day.

As a result, on the 8th day of storage, the weight of the tomato in Comparative Example 1 was reduced by 30.34%, the water of the tomato was lost, and the tomato was spoiled and wormed, and it was already in an inedible state. The weight of the tomatoes of Example 1 was reduced by 11.70%, and the moisture and freshness were maintained well, and they were in a usable state. That is, the weight loss was reduced by 74% in the implementation case 1 compared with the comparative case 1.

An alternating electric field with suitable strength will be formed inside, and in the fresh-keeping space 5 where the alternating electric field is formed, the preservation period of the fresh product 4 at room temperature can be extended.

<Effect of alternating electric field affecting freshness treatment when using a refrigerator>

Hereinafter, the effect of the alternating electric field affecting the fresh-keeping process according to the fresh-keeping device when the fresh-keeping device according to the first embodiment is installed on a refrigerator as a delimiting part for delimiting the fresh-keeping space will be described.

First, the fresh-keeping device without the space potential generating device is taken as the comparative example 2, and the fresh-keeping device equipped with the space potential generating device 6, that is, the fresh-keeping device of the present embodiment 1, is taken as the implementation example 2.

The fresh-keeping device in the comparative case 2 and the implementation case 2 is installed in the refrigerator, thereby forming a fresh-keeping space, and the size of the fresh-keeping space is 80 cm wide x 150 cm high x 50 cm long. The electrode part 2 installed in the fresh-keeping device of Example 2 is composed of an electrode plate with a length of 30 cm x a width of 15 cm x a thickness of 1 mm. Diene (Butadiene), styrene (Styrene) copolymer synthetic resin (ABS resin) board). The size of the insulating material covered on the electrode plate is length 40cm x width 35cm x thickness 4mm, and the size of the insulating material covered under the electrode plate is length 40cm x width 35cm x thickness 4mm.

In the refrigerators installed with the fresh-keeping device in the comparative case 2 and the implementation case 2, chicken was selected for the comparison of refrigerated storage. The voltage applied to the electrode part 2 was set to 800V, and the voltage directly applied to the chicken was set to 30V. The temperature in the refrigerator was 5°C, and the storage period was from the day when the experiment started as the first day to the fourth day.

As a result, by the fourth day, the chicken of Comparative Case 2 was already bleeding, and the loss of nutrients resulted in poor taste and discoloration. The chicken in Example 2 had almost no blood flow out, and was still fresh, and the color of the chicken was hardly changed from the color on the day when the experiment was started.

In addition, in the refrigerator with the fresh-keeping device installed in the comparative case 2 and the implementation case 2, spinach was used to compare the effect of refrigerated storage. The voltage applied to the electrode part 2 was set to 800V, and the voltage directly applied to the spinach was set to 30V. The temperature in the refrigerator was 4°C, and the storage period was from the day when the experiment started as the first day to the 19th day.

As a result, by the 19th day, the spinach of Comparative Case 2 had withered and had a great change in appearance, while the spinach of Implementation Case 2 had not withered and hardly changed in appearance.

As can be seen from the results of the above experiments, when the fresh-keeping device of the first embodiment is used, the electrode part 2 is installed in the fresh-keeping space 5 by providing the space potential generating device 6, and the electrode part 2 is installed in the refrigerator 1.

<Preservation status of frozen fresh products in the fresh-keeping device>

Next, the preservation state of the fresh product frozen in the fresh-keeping apparatus according to the first embodiment will be described.

First, the fresh-keeping device without the space potential generating device is taken as the comparative example 3, and the fresh-keeping device equipped with the space potential generating device 6, that is, the fresh-keeping device of the present embodiment 1, is taken as the implementation example 3.

The fresh-keeping device in Comparative Case 3 and Implementation Case 3 is installed in the freezer compartment of the refrigerator, thereby forming a fresh-keeping space with a size of 60cm long x 80cm high x 45cm wide. The electrode part 2 installed on the fresh-keeping device of Example 3 is composed of a planar electrode plate with a length of 10 cm × a width of 5 cm. The upper and lower surfaces of the electrode plate are covered with insulating plastic (PE plate). The size of the insulating material covered on the top of the electrode plate is 12 cm in width x 17 cm in length x 7 mm in thickness, and the size of the insulating material covered on the bottom of the electrode plate is 12 cm in width x 17 cm in length x 6 mm in thickness.

In the freezer of the refrigerator with the fresh-keeping device installed in the comparative case 3 and the implementation case 3, beef was selected for the comparison of frozen preservation. The temperature of the freezer was -24°C, and the freezing period was the first day of the experiment, and ended on the seventh day. Then, the frozen beef was taken out on day 7 and thawed at 4°C for 24 hours. The voltage applied to the electrode part 2 was set to 1000V, and the voltage directly applied to the beef was set to 20V.

FIG. 4 is a photograph of beef frozen and then thawed in the freezer compartment of a refrigerator equipped with a fresh-keeping device in Comparative Example 3 and Implementation Example 3. FIG. The left side of FIG. 4 is a photograph of beef frozen and thawed in the refrigerator freezer of Comparative Example 3, and the right side of FIG. 4 is a photograph of beef frozen and thawed in the refrigerator freezer of Example 3.

As shown on the left side of Fig. 4, the thawed beef in Comparative Example 3 had blood water of 3.28% by weight, and nutrients were lost. On the other hand, as shown on the right side of FIG. 4 , the thawed beef in Example 3 only bleeds out 0.69% of its blood, which is still fresh.

The fresh-keeping device in Comparative Case 3 and Implementation Case 3 was installed in the freezer compartment of the refrigerator, and Ise shrimp was selected for the comparison of freezing. The temperature in the freezer was -24°C, and the freezer period was the first day of the experiment, and ended on the seventh day. On the 7th day, take out the shrimp and thaw at room temperature. The voltage applied to the electrode part 2 was set to 1800V, and the voltage directly applied to the ishe shrimp was set to 30V.

Fig. 5 is a photograph of the Ise shrimp frozen and then thawed in the freezer compartment of the refrigerator equipped with the preservation device in the comparative example 3 and the implementation example 3. The left side of FIG. 5 is a photograph of Ise shrimp frozen and thawed in the freezer of the refrigerator of Comparative Example 3, and the right side of FIG. 5 is the freezer of the refrigerator of Example 3 of implementation.

As shown on the left side of Fig. 5, the body of the thawed Ise shrimp in Comparative Example 3 has become soft, and the part of the gut called the shrimp paste has also been deformed. On the other hand, as shown on the right side of Fig. 5, the Ise shrimp thawed in Example 3 had a firm body, and the shape of the midgut was well maintained.

The fresh-keeping device in the comparative case 3 and the implementation case 3 is installed in the freezing chamber of the refrigerator, and abalone is selected for the comparison of freezing. The temperature in the freezer was -24°C, and the freezer period was the first day of the experiment, and ended on the seventh day. Remove the abalone on day 7 and thaw. The voltage applied to the electrode portion 2 was set to 2000V, and the voltage directly applied to the abalone was 25V.

FIG. 6 is a photograph of abalone that has been frozen and then thawed in the freezer compartment of the refrigerator installed with the preservation device in the comparative example 3 and the implementation example 3. FIG. The upper part of FIG. 6 is a photograph of abalone frozen and thawed in the freezer of the refrigerator of Comparative Example 3, and the bottom of FIG. 6 is a photograph of abalone frozen and thawed in the freezer of the refrigerator of Example 3.

The upper part of Figure 6 shows that the thawed abalone in Comparative Case 3 has a large amount of blood and water flow, the body has become soft, and the liver has been damaged. The bottom part of Figure 6 shows that the thawed abalone in Example 3 had less blood flow, little softening of the body, and well-preserved liver. In addition, when the thawed abalone was heated, the abalone of Comparative Example 3 had shrinkage and granulation, that is, the granular part of the surface protruded, and it was soft to eat. And although the abalone body of the implementation case 3 also shrunken, it tasted more chewy.

Using the fresh-keeping device of the first embodiment, the agglomeration effect can freeze water molecules without destroying cells. Because the freshness of frozen ingredients can be maintained, compared with using a blast freezer, there is no need to remove the frozen ingredients from the blast freezer and transfer them to the freezer. In this way, it is not necessary to introduce expensive rapid freezing equipment, and it is possible to reduce electricity bills and carbon dioxide emissions by simply installing the space potential generator 6 on the existing freezing equipment.

In addition, a fresh-keeping device without a space potential generator and equipped with a freezer is used as Comparative Example 4, and a fresh-keeping device equipped with a space potential generator 6 and a freezer according to Embodiment 1 is used as Example 4. Then, using the fresh-keeping devices of Comparative Example 4 and Implementation Example 4, the temperature was set to -18°C, and the food was frozen for comparison. As a result, in Comparative Example 4, the ice crystals adhering to the foodstuffs after freezing were larger, while the ice crystals in the foodstuffs after freezing in Example 4 were smaller. This is because the agglomeration of water molecules becomes smaller when the fresh-keeping device of Example 4 is frozen. This shows that by adding a space potential generating device to the existing freezer, the best freezing effect can be achieved without destroying the fibers of the food.

In addition, comparing the fresh-keeping device in Case 4, the quality of the food will deteriorate after being frozen at -18°C for one month, and if stored for more than one month, the food will still deteriorate in the frozen state and become inedible. However, the fresh-keeping device of Case 4 can maintain the freshness for one year. Freshness after freezing can also lock in moisture for high-quality freezing.

FIG. 7 is a photograph of pork frozen and then thawed in a freezer equipped with the fresh-keeping device of Comparative Example 4 and Example 4, respectively. The left side of Fig. 7 is a photograph of pork thawed at room temperature after being frozen at a temperature of -18°C for three months in the freezer of Comparative Example 4, and the right side of Fig. 7 is a freezer of Example 4 at a temperature of -18°C Photo of pork thawed at room temperature after three months of freezing.

As shown on the left side of Fig. 7, the thawed pork in Comparative Example 4 has become no longer red and is in an inedible state. On the other hand, as shown on the right side of Fig. 7, the thawed pork in Example 4 has almost no change in color, is still red, and is still fresh.

For example, if an ISO container or a refrigerated truck for transport is currently transported overseas in an ISO container at a temperature of -20°C for 2 weeks, by installing the space potential generator 6 on the existing refrigerated warehouse, it is possible to - Shipped fresh at 5°C. This saves electricity bills and reduces carbon dioxide emissions.

＜Installation on fishing boats＞

Next, a description will be given of an example in which the fresh-keeping device according to Embodiment 1 is attached to a fishing boat storage.

Conventionally, when the fish caught in the storage tank of the fishing boat are stored, the weight is reduced by 30% from the first storage to the seventh day. Even in summer, the weight will be reduced by 50% from the start of preservation to the 7th day. Weight loss is closely related to fish freshness, and how to reduce weight loss has always been a problem.

The fresh-keeping device of the first embodiment was installed in the fishing boat storage tank as the fresh-keeping device of the fifth embodiment, the foam container was filled with water, the temperature of the preserved fish was set to -1°C, and the electrode part was applied. The voltage was set at 30-50V, and the experiment was started on the first day until the seventh day. On the other hand, the freshness of fish preserved in Example 5 and Comparative Example 5 was compared by using a storage bank without a space potential generating device as the fresh-keeping device of Comparative Example 5.

In Comparative Example 5 and Implementation Example 5, the size of the fresh-keeping space with the fresh-keeping device installed in the storage warehouse is 4 m in width x 3 m in height x 5 m in length. The electrode part 2 installed on the fresh-keeping device of Example 5 is composed of an electrode plate with a width of 15 cm × a length of 25 cm, and the upper and lower surfaces of the electrode plate are covered with a plastic insulating material (PE plate). The size of the insulating material covered on the electrode plate is width 25cm x length 35cm x thickness 6mm, and the size of the insulating material covered under the electrode plate is width 25cm x length 35cm x thickness 6mm. The voltage application device 3 applies an alternating voltage to the electrode part 2 to ensure that the electrode part 2 discharges static electricity, so that the voltage in the storage room is 20V, and the food is stored in a foam plastic box in the storage room. The voltage on is also 20V.

FIG. 8 is a photograph of fish frozen and then thawed in a storage chamber equipped with a fresh-keeping device in Comparative Example 5 and Implementation Example 5. FIG. The left side of FIG. 8 is a photograph of fish stored in the repository of Comparative Example 5, and the right side of FIG. 8 is a photograph of fish stored in the repository of Example 5.

Comparing the comparative case 5 and the implementation case 5 in Fig. 8, it will be found that the eyes of the fish in the comparative case 5 are white, and the eyes of the fish in the implementation case 5 are black, which are completely different. From this, it can be seen that the freshness of the fish in the storage can be improved by installing the fresh-keeping device of the first embodiment in the storage of the fishing boat.

＜Preservation effect of chestnuts＞

Next, the fresh-keeping effect of chestnuts when using the fresh-keeping device of the first embodiment will be described.

First, the fresh-keeping device without the space potential generating device is used as the comparative example 6, and the fresh-keeping device equipped with the space potential generating device 6, that is, the fresh-keeping device of the present embodiment 1 is used as the embodiment example 6.

In the comparative case 6 and the implementation case 6, the size of the fresh-keeping space with the fresh-keeping device installed in the storage warehouse is 50 cm in length x 30 cm in height x 45 cm in width. The electrode part 2 installed on the fresh-keeping device of Example 6 is composed of a flat electrode plate with a width of 15 cm × a length of 25 cm, and the upper and lower surfaces of the electrode plate are covered with a plastic insulating material (PE plate). The size of the insulating material covered on the electrode plate is width 25cm x length 35cm x thickness 6mm, and the size of the insulating material covered under the electrode plate is width 25cm x length 35cm x thickness 6mm.

The ingredients are chestnuts, and the appearance changes and sugar content are compared. In Comparative Example 6, the storage room temperature was set to normal temperature or 5°C, and the storage period was one to two months. The storage room temperature of Example 6 is set to normal temperature, 0°C or -2°C, and the storage period is one to two months.

Photo of chestnuts.

The results showed that, comparing the chestnuts stored at room temperature in Case 6, three samples had mold on the surface after one month, and the average sugar content of the three samples was 2.5. After one and a half months, the mold of the three samples expanded, and the sugar content could not be measured. The photo on the left side of Figure 9 is one of the 3 samples in this group that have been stored for one and a half months.

Comparing the chestnuts stored at 5°C in Case 6, the appearance of the three samples did not change significantly after one month, and the average Brix was 6.93. After one and a half months, the 3 samples had a lot of mold, and the Brix could not be measured.

For the chestnuts stored at room temperature in Example 6, the surface of the three samples was moldy after one month, and the average Brix was 4.46. After one and a half months, the three samples became more moldy, and the Brix could not be measured.

For chestnuts stored at 0°C in Example 6, the appearance of the three samples did not change significantly after one month, and the average Brix was 6.26. After 2 months, there was still no obvious change in appearance, and the average Brix was 11.26.

For chestnuts stored at -2°C in Example 6, the appearance of the three samples did not change significantly after one month, and the average Brix was 6.53. After 2 months, there was still no obvious change in appearance, and the average Brix was 21.43. The photo on the right side of Figure 9 is one of the 3 samples in this group that were stored for 2 months.

It can be seen from the above-mentioned mildew situation and the comparison of the right and left photos of FIG. 9 that the freshness of the chestnuts will be significantly improved when the chestnuts are preserved by using the fresh-keeping device of the first embodiment. In addition, it can be seen from the difference in the above-mentioned sugar content that when chestnuts are preserved by using the fresh-keeping device of the first embodiment, the sugar content of chestnuts is significantly increased. It can be concluded that the present embodiment can achieve fresh-keeping and long-term preservation of chestnuts.

<Effect of the voltage adjustment section>

In a refrigerator with a fresh-keeping space, when the space inside is divided into several spaces by a partition plate, the discharge plate serving as the electrode part 2 can be increased, but the voltage may be insufficient.

Embodiment 2

＜Fryer＞

Next, the deep fryer of the second embodiment will be described. The fryer of the second embodiment is equipped with a space potential generating device, which is an electric field forming device that forms an alternating electric field.

14 is a cross-sectional view schematically showing an example of the fryer apparatus according to the second embodiment. As shown in FIG. 14 , the fryer apparatus according to the second embodiment includes an oil tank 61 , an electrode portion 2 , and a voltage applying device 3 . The oil tank 61 contains the oil 61a. The electrode part 2 is installed in the oil tank 61 , and is preferably submerged in the oil 61 a in the oil tank 61 . The voltage applying device 3 applies an alternating voltage VL1 (see FIG. 3 ) to the electrode portion 2 to form an alternating electric field in the oil groove 61 . The electrode portion 2 and the voltage applying device 3 constitute a space potential generating device 6 that generates an alternating electric field in the oil tank 61 .

However, the fryer of the second embodiment may not be provided with the oil tank 61 . In this case, the fryer device provided only with the electrode part 2 and the voltage applying device 3 can be used in combination with the oil tank.

The electrode portion 2 and the voltage applying device 3 mounted on the fryer device of the second embodiment can be the same as the electrode portion 2 and the voltage applying device 3 mounted on the fresh-keeping device of the first embodiment, so the details about the same are omitted. detailed description.

The fryer device of the second embodiment is combined with the oil tank 61 and the space potential generating device 6, the electrode part 2 discharges static electricity into the oil tank 61, and an alternating electric field is formed in the oil tank 61, and the formed alternating electric field is applied to the oil tank 61.

As a result, the initial investment cost and long-term operation cost of the fryer device can be reduced, and at the same time, the effect of the alternating electric field affecting the fryer frying process can be improved.

<Effect of alternating electric field affecting frying process>

Next, the effect of the alternating electric field which affects the frying process generated by the fryer of the second embodiment will be described.

First, a fryer without a space potential generating device is used as a comparative example 7, and a fryer equipped with the space potential generating device 6, that is, the fryer of the present embodiment 2 is used as an example 7. The electrode part 2 attached to the fryer of Example 7 is an electrode part whose upper and lower surfaces are covered with an insulating material. The same sample ingredients were placed in the oil tanks of the fryer of Comparative Example 7 and Example 7, and after continuous frying, the color and smell in the oil tanks were compared.

The fryer oil tanks of Comparative Example 7 and Implementation Example 7 were each filled with 6 liters of oil. The electrode part 2 installed on the fryer of Example 7 is composed of an electrode plate with a width of 5 cm × a length of 10 cm × a thickness of 1 mm. registered trademark) made of PTFE material. This kind of PTFE material can be heat resistant up to 260℃. The insulating material covered on both sides of the electrode plate is all 1cm long x 1cm wide x 5mm thick, covering both sides or one side. In addition, the electrode part 2 is built in the fryer and covered with an insulating material to prevent electric leakage.

For connecting the output terminal 34 (see FIG. 3 ) of the voltage applying device 3 and the power supply wire 24 of the electrode part 2 , a wire covered with an insulating material made of Teflon (registered trademark) PTFE was used. This kind of PTFE material can be heat resistant up to 260℃. In addition, in order to exclude the influence of other conditions during the comparison, a distance of 4 meters was used between the fryer of Comparative Case 7 and the implementation of Case 7.

Further, the voltage applied to the electrode portion 2 was set to 800V, and the voltage directly applied to the oil 61a stored in the oil tank 61 was also set to 800V.

The specific method is to fry 28kg of chicken (coated with starch), 300 grams each time, and continuously fry the oil. After frying, compare the color, smell, acid value (AV (Acid Value)), peroxide value (POV ( Peroxide Value) and acrylamide (Acrylamide). The color is judged by visual observation, and the odor is judged by a odor judge with national qualifications recognized by the Ministry of the Environment. The acid value refers to the deterioration standard value unified in Japan. Although there is no generally accepted standard value for deterioration of the peroxide value, this value was measured in consideration of various evaluations.

Regarding the chemical substance acrylamide contained in food, the Food Safety Committee of the Cabinet Office of Japan announced it as a "genotoxic carcinogen". In addition, the FDA (U.S. Food and Drug Administration: Food and Drug Administration) reported in the "FDA Draft Action Plan for Acrylamide in Food" (FDA draft action plan on acrylamide in food) that in processed foods, the Acrylamide with risk of carcinogenicity or genetic damage. Even, on April 24, 2002, a joint research team composed of the Swedish National Food Agency and Stockholm University showed that after raw materials containing more carbohydrates are fried or grilled at a high temperature above 120 ° C, the food will contain acrylamide components. Due to the risk of carcinogenicity of acrylamide, the formation of acrylamide was also examined.

According to the above conditions, in order to ensure the same frying conditions, the same amount of ingredients were fried in the fryer of Comparative Case 7 and Example 7 for 3 consecutive days, and then the oil was extracted from the fryer to compare each item. . In order to ensure that the core temperature after frying reaches 75°C, measure the temperature with a thermometer.

As a result, Example 7 had a better effect of suppressing oil deterioration than Comparative Example 7 in terms of color, odor, acid value, and peroxide value. Moreover, compared with the comparative example 7, the amount of acrylamide produced|generated in Example 7 was reduced to 1/4.

Regarding the color of the oil, between the comparative case 7 and the implementation case 7, the color difference of the oil on the second day of the start of the experiment was compared. Here, the color difference refers to comparing the difference between the oil before cooking and the oil after cooking using the L×a×b color system, where L is brightness, +a is red, -a is green, +b is yellow, and -b is blue. A color difference value (dE) of 6.0 or more is judged to be large according to the NBS (National Bureau of Standards) standard.

As a result, the color of the oil of the fryer of Example 7 was brighter than that of the fryer of Comparative Example 7, and the color difference value was 6.43. It can be seen that the oil of the fryer of Comparative Example 7 was dirty.

About the odor of oil, between the comparative case 7 and the implementation case 7, it evaluated by several inspectors including odor judges. As a result, "the oil of Example 7 had a weaker odor reminiscent of the taste of fried chicken nuggets than the oil of Comparative Example 7", indicating that the taste of ingredients such as fried chicken nuggets was less likely to remain in the oil.

In addition, the oil of Example 7 and the oil of Comparative Example 7 were also compared visually. The result was that the oil of Comparative Example 7 had black spots and foam. After the experiment was over, 200 grams of French fries were fried. When the last 100 grams of French fries were fried, the hood was almost as big as the water vapor in the bathroom. The working environment deteriorates significantly, and it will produce a sticky feeling and oily smoke smell. However, in Example 7, no foam was generated, and the oil surface was clean.

Regarding the peroxide value, between the comparative case 7 and the implementation case 7, an experiment of frying 200 g of french fries for 3 days was conducted, and then the state of the oil was compared. As a result, the oil of the fryer of Example 7 had a peroxide value of 1.89, while the oil of the fryer of Comparative Example 7 had a peroxide value of 2.77, and the deterioration of the oil of Example 7 was reduced compared with that of Comparative Example 7 up 32%.

In addition, regarding acrylamide, between Comparative Example 7 and Implementation Example 7, after the above-mentioned experiment was completed, 100 g of French fries were fried, and the content of acrylamide in the French fries was compared. As a result, the acrylamide content of French fries fried in the deep fryer of Comparative Example 7 was 425 μg/kg, and the acrylamide content of French fries fried in the deep fryer of Example 7 was 113 μg/kg. The deep fryer can reduce the acrylamide content to 1/4. Acrylamide presents a carcinogenic risk, often produced in degraded oils, and is also of international concern. Therefore, the fact that the space potential generator 6 can reduce the content of acrylamide is of great significance.

Next, 80 g of French fries were put into the oil stored in the oil tank of the fryer of Comparative Example 7 and Example 7, respectively, and fried at an oil temperature of 170° C. to compare the changes in oil.

As a result, in the fryer of Comparative Example 7, the water in the ingredients in the fryer combined with the oil to cause emulsification, and the water was mixed into the oil. In the fryer of Example 7, the oil was combined with the electrons and not with the water. Therefore, The water in the ingredients evaporates quickly and is not mixed into the oil. In this way, the temperature of the oil can be kept at a constant temperature, and the frying time can be shortened. In addition, in the fryer of Example 7, only water was evaporated as water vapor. Therefore, the oil stains around the fryer are reduced, and the environment is more hygienic without being attached to the kitchen and store. Furthermore, the fryer of Example 7 can suppress the evaporation of oil. In this way, the smell of oil generated during frying can also be suppressed, which can prevent customers' clothes from being stained with the smell of oil.

Frozen chicken nuggets were also fried to compare frying times in the fryer of Comparative Example and Implementation Example 7.

Do not pour 6 liters of oil into the fryer oil tank in Comparative Case 7 and Example 7. Both fryers were set to 165°C and the core temperature of the chicken nuggets were measured at 2 minutes 30 seconds and 3 minutes for comparison.

As a result, in the fryer of Example 7, the core temperature of the chicken nuggets was 83.6°C and 95°C at 2 minutes 30 seconds and 3 minutes, respectively. For the fryer of Comparative Example 7, at 2 minutes 30 seconds and 3 minutes, the core temperature of the fried chicken nuggets was 34.6°C and 80°C, respectively. In the fryer of Example 7, the thermal conductivity of the oil is higher, and the frying time can be shortened.

In addition, after installing the space potential generating device 6 in a fryer that consumed 405 liters of oil (22.5 cans) for one month in an actual shop, the frying temperature was lowered from 180°C before installing the space potential generating device. to 170°C. In this way, the monthly usage of oil in this store has been reduced to 108 liters (six cans), a reduction of 73%. And the frying time is also shortened by more than 10%, and the work efficiency is also improved.

As a result, the fryer according to the second embodiment equipped with the space potential generating device 6 installed in the oil tank 61 forms an alternating electric field in the oil tank 61 by the space potential generating device 6, thereby improving the thermal conductivity of the oil and frying. The ingredients that have been passed are also crispy, which can achieve very good results. Moreover, because the water vapor evaporates quickly, there will be no oil fume, and the staff in the kitchen will not feel pain in the eyes.

Embodiment 3

<Water activation device>

Next, the water activation device of Embodiment 3 will be described. In the water activation device of the third embodiment, an alternating electric field is formed in a water tank, and the water stored in the water tank in which the alternating electric field is formed is electrolyzed, that is, activated. In addition, the water activation device of the third embodiment is equipped with a space potential generating device, that is, an electric field forming device that forms an alternating electric field.

15 is a cross-sectional view schematically showing an example of a water activation device according to Embodiment 3. FIG. As shown in FIG. 15 , the water activation device of the third embodiment includes a water tank 62 , an electrode part 2 , and a voltage applying device 3 . The water 62a is stored in the water tank 62 . The electrode part 2 is installed in the water tank 62 , preferably immersed in the water 62 a stored in the water tank 62 . The voltage applying device 3 applies an alternating voltage VL1 (see FIG. 3 ) to the electrode portion 2 to form an alternating electric field in the water tank 62 . Through the electrode portion 2 and the voltage applying device 3, a space potential generating device 6 for generating an alternating electric field is formed in the water tank 62.

However, the water activation device of the third embodiment may not have the water tank 62 . In this case, the water activation device constituted only by the electrode part 2 and the voltage applying device 3 can be combined with a water tank to electrolyze and activate the water. And even if the electrode part 2 is not immersed in the water 62a, the same effect as when the electrode part 2 is immersed in the water 62a can be obtained.

The electrode part 2 and the voltage applying device 3 mounted on the water activation device of the third embodiment can be the same as the electrode part 2 and the voltage applying device 3 mounted on the fresh-keeping device of the first embodiment, so the details about the same are omitted. detailed description.

The water activation device of the third embodiment is composed of a water tank 62 and a space potential generator 6 combined. The electrode part 2 discharges static electricity into the water tank 62, and an alternating electric field is formed in the water tank 62. The formed alternating electric field It is applied to the water 62a stored in the water tank 62 to activate the water 62a. In this way, the initial introduction cost and long-term operation cost of the water activation device are reduced, and the alternating electric field formed by the space potential generating device 6 can better activate the water 62a stored in the water tank 62 .

When direct current is applied between the two electrodes to electrolyze water, active oxygen (OH, etc.) will be generated at the anode, and the formed active oxygen will oxidize various organic substances, and hydrogen (H ⁺ ) will be generated at the cathode. Hydrogen reduces various organics. Alternatively, when a direct current is applied between two electrodes to electrolyze water containing chloride ions (Cl ⁻ ) such as seawater, hypochlorous acid (HClO) is generated at the anode, and the formed hypochlorous acid can oxidatively decompose bacteria and the like. Or when a direct current is applied between the two electrodes to electrolyze water containing chloride ions and ammonia nitrogen (NH ₃ ), the ammonia nitrogen will react and be converted into harmless nitrogen (N ₂ ).

On the other hand, only one electrode part 2 is attached to the water activation device of the third embodiment. In this case, when an alternating voltage is applied to the electrode portion 2, the electrode portion 2 becomes an anode and becomes a cathode for a while, and the electrode portion 2 alternately reciprocates. Therefore, when the water is electrolyzed, the electrode part 2 generates hydrogen and active oxygen, when the water containing chloride ions is electrolyzed, hypochlorous acid is generated, and when the water containing chloride ions and ammonia nitrogen is electrolyzed, when nitrogen is produced.

In this way, when various organic substances exist in the water 62a stored in the water tank 62, these organic substances can be acidified and removed, and when bacteria and the like exist in the water 62a, these bacteria can be oxidized and decomposed and sterilized. When ammonia nitrogen is produced, ammonia nitrogen can be converted into nitrogen and removed. That is, the water 62a stored in the water tank 6 can be activated.

In addition, the water activation device of the third embodiment is also the same as the fresh-keeping device of the first embodiment, and is equipped with a space potential generating device 6 composed of an electrode part 2 and a voltage applying device 3. The voltage applying device 3 is the same as that of the fresh-keeping device of the first embodiment. The same device is provided with a voltage adjustment unit 41 (see FIG. 3 ). In this way, the intensity of the alternating electric field in the water tank 62 can be adjusted to an optimum intensity according to the type or quantity of organic matter or bacteria present in the water 62a, or the content of ammonia nitrogen in the water 62a. Thereby, both the initial investment cost and the long-term operation cost of the water activation device are reduced, and the effect of the alternating electric field affecting the activation treatment of the water activation device is also improved.

<Effect of alternating electric field affecting activation treatment>

Fifteen goldfish with a size of 15 cm in length x 2 cm in width x 10 cm in height were placed in a water tank 62 of 80 cm in width x 2 m in length x 50 cm in height for a 6-month breeding experiment.

The electrode part 2 installed in the water tank 62 is composed of an electrode plate with a width of 5cm x a length of 10cm x a thickness of 1mm. The upper and lower sides of the electrode plate are provided with insulating feet. The insulating backing plate is made of insulating material Teflon (registered trademark). ) PTFE (Polytetrafluoroethylene). The insulating material covered on both sides of the electrode plate is all 1cm wide x 1cm long x 5mm thick, covering both sides or one side of the electrode plate. However, the electrode plate may have other shapes. In addition, the electrode plate is built into the wall of the water tank, and if the insulating panel is covered, leakage of electricity can also be prevented.

An alternating current of 2200 V was applied to the electrode plates, and 15 goldfish were cultured for 6 months as described above. No cleaning was done at all for 6 months, and the filter part was also not cleaned at all. Also, the filtered part does not see light and is placed in a dark environment that avoids sunlight. Feed the fish food 1 to 2 times a day and breed according to normal farming methods.

As a result, after 6 months, the surface inside the sink was completely free of contamination and remained clean. In addition, the water tank and the filter part are also the same, the water is not cloudy at all, and there is no smell at all, and the water quality is good. In this way, the voltage can be adjusted according to the size of the tank and the amount of water to create the most suitable environment for aquatic life. Since the electrode plate can be installed in the water tank 62, the cells of the fish are also activated, and the fish itself becomes healthy. If two electrodes are installed in the tank to form an alternating electric field, fish cannot survive in the water, but if only one electrode plate is used to form an alternating electric field, there can be fish in it. That is, the water activation device of the third embodiment activates water and can purify water by electrolysis.

<Effect of the voltage adjustment section>

With the voltage adjustment part 41 in the water activation device of the third embodiment, the voltage applied to the electrode part 2 can be adjusted according to the size of the water tank or the number of fish. If the alternating electric field applied to aquatic organisms such as fish is too strong, it will adversely affect aquatic organisms. The voltage adjustment unit 41 in the water activation device of the third embodiment can be used without adversely affecting aquatic organisms. Under the premise of water activation treatment.

Embodiment 4

＜Cultivation device＞

Next, the culture apparatus of Embodiment 4 will be described. In the culture apparatus of the fourth embodiment, an alternating electric field is formed in a water tank, and aquatic organisms are cultured in the water tank in which the alternating electric field is formed. In addition, the cultivation device of the fourth embodiment is equipped with a space potential generating device, which is an electric field generating device that forms an alternating electric field.

An example of a cross-sectional view of the culture apparatus of Embodiment 4 is schematically shown. As shown in FIG. 16 , the culture apparatus of the fourth embodiment includes a water tank 63 , an electrode part 2 , and a voltage applying device 3 . In the water tank 63, water 63a such as seawater is stored. The electrode part 2 is installed in the water tank 63 , and is preferably submerged in the water 63 a stored in the water tank 63 . The voltage applying device 3 applies an alternating voltage VL (see FIG. 3 ) to the electrode portion 2 to form an alternating electric field in the water tank 63 . The electrode portion 2 and the voltage applying device 3 constitute a space potential generating device 6 that forms an alternating electric field in the water tank 63 .

However, the culture apparatus of the fourth embodiment may not have the water tank 63 . In this case, the culturing device composed of only the electrode part 2 and the voltage applying device 3 can be combined with a water tank and used for culturing aquatic organisms.

The electrode part 2 and the voltage applying device 3 mounted on the cultivating device of the fourth embodiment can be the same as the electrode part 2 and the voltage applying device 3 mounted on the fresh-keeping device of the first embodiment, so the details about them are omitted. illustrate.

In the culture apparatus of the fourth embodiment, static electricity is discharged from the electrode unit 2 into the water tank 63, an alternating electric field is formed in the water tank 63, and the formed alternating electric field is applied to the aquatic organisms 63b such as fish, whereby the aquatic organisms 63b are cultured. . At this time, the effect of the alternating electric field causes the water molecules in the aquatic organism 63b to be irradiated with electromagnetic waves of a specific wavelength, activates the cells in the aquatic organism 63b, activates the vitality of the aquatic organism 63b, and breeds the aquatic organism 63b.

The cultivating apparatus of the fourth embodiment is equipped with an ordinary water tank 63 , the electrode part 2 , and the voltage applying device 3 . As described above, the effect of the alternating electric field activates the vitality of the aquatic organism 63b and breeds the aquatic organism 63b. Therefore, the cultivation device of the fourth embodiment can reduce the initial introduction cost and long-term operation cost of the cultivation device, and the effect of the alternating electric field formed by the space potential generating device 6 can better cultivate aquatic organisms 63b.

In addition, the electrode portion 2 vibrates at a low frequency physically, and the alternating electric field is conducted around the electrode portion 2 in accordance with the low-frequency vibration, so that an electric field can be formed in a wide range.

Using the traditional method, if two AC electrodes are installed, the current value is 10-20A, and the current is relatively high. Aquatic organisms such as fish or aquaculture workers may be electrocuted, so electrodes cannot be placed in the tank. Therefore, two electrodes are installed outside the water tank, seawater or fresh water taken out from the water tank passes between the two electrodes, and the electrodes apply high-voltage electricity to the water to perform sterilization treatment. In this case, the sterilization treatment can be performed only when the water is circulated outside the water tank, and stability is lacking.

On the other hand, in the cultivation apparatus of the fourth embodiment, since a low-voltage and low-frequency AC voltage is applied to the electrode portion 2, the aquatic organisms 63b such as fish and people are not electrocuted and can be used safely. Furthermore, since the cells are activated, the vitality of the aquatic organisms 63b such as fish cultured in the water tank 63 can also be activated. Specifically, the fish whose skin color has turned black and are not very active are put into the water tank 63 for culture, and the day when the culture starts is the first day. On the fifth day, the fish start to become active and turn black. The epidermis is gone and rejuvenated.

In addition, the culturing device of the fourth embodiment is also the same as the fresh-keeping device of the first embodiment, and is equipped with a space potential generating device 6 composed of an electrode part 2 and a voltage applying device 3, and the voltage applying device 3 is the same as the fresh-keeping device of the first embodiment. , with a voltage adjustment unit 41 (refer to FIG. 3 ). In this way, the intensity of the alternating electric field in the water tank 63 can be adjusted to the most appropriate intensity according to the type or quantity of the aquatic organisms 63b to be cultivated. As a result, the initial investment cost and long-term operation cost of the breeding device will be reduced, and at the same time, the effect of the alternating electric field affecting the breeding treatment will also be improved because of the breeding device.

<Effect of the voltage adjustment section>

By the voltage adjustment part 41 in the culture apparatus of this Embodiment 4, the voltage applied to the electrode part 2 can be adjusted according to the size of a tank or the number of fishes. If the alternating electric field applied to aquatic organisms such as fish is too strong, it may have adverse effects on aquatic organisms. With the voltage adjustment unit 41 in the aquaculture apparatus of the fourth embodiment, it is possible to achieve no adverse effects on aquatic organisms. breeding treatment.

In this Embodiment 5, the electrode part 2 hangs down from the ceiling 64d of the room temperature storage 64. As shown in FIG. The electrode part 2 is provided with a flexible and flexible output plate (discharge plate or discharge plate), that is, a plate-like electrode 2a. The plate-like electrode 2a is attached to the screen 64f, and the screen 64f can be wound because of the winding portion 64e. When the space potential generating device 6 is used, the plate-like electrode 2a hangs down together with the screen 64f pulled down from the winding portion 64e; Section 64e rolls up. The plate-shaped electrode 2a can exert the effect of the alternating electric field from both the front and the back. The hanging down and rolling up of the screen 64f can be manually controlled using, for example, the remote controller 64g, or can be automatically controlled according to temperature or time.

In this way, the freshness of the storage object 64a stored in the normal temperature storage box 64 can be maintained for a long period of time. The initial introduction cost and long-term operation cost of the storage device can be reduced, and the freshness of the storage object 64a in the storage space 64b can also be maintained for a long time due to the effect of the alternating electric field formed by the space potential generating device 6 . However, the electrode portion 2 is covered with an insulating material, which is omitted in FIGS. 17 and 18 . In addition, the room temperature storage box 64 may be a storage box of the size of a household refrigerator.

It is preferable to attach the electrode part 2 to the center position of the plan view of the storage space 64b formed in the normal temperature storage chamber 64 . In this way, a uniform alternating electric field can be formed in the normal temperature storage chamber 64, that is, in the storage space 64b.

<Effect of alternating electric field affecting preservation process>

Next, the effect of the alternating electric field that affects the storage process in the storage device according to the fifth embodiment will be described.

First, a storage device without a space potential generating device is used as a comparative example 8, and a storage device of the present embodiment 5 equipped with a space potential generating device is used as an example 8. Furthermore, in order to investigate the net effect of the alternating electric field formed by the space potential generating device, the upper and lower surfaces of the electrode part 2 mounted on the fresh-keeping device of Example 8 were not covered with insulating material.

Plants inserted in vases containing half a bottle of water were placed in the normal temperature storage chambers 64 respectively equipped with storage devices in Comparative Case 8 and Example 8, and the day when the experiment was started was the first day, and the plants were stored in the normal temperature storage chambers. 64 were stored until the 8th day, and the preservation status of the plants on the 8th day was compared. In Comparative Example 8 and Example 8, the temperature in the room-temperature storage room equipped with the storage device was 20 to 30°C. The voltage applied to the electrode part 2 was set to 2000V, and the voltage directly applied to the plant was set to 50V.

19 and 20 are photographs of plants preserved in the preservation apparatuses of Comparative Example 8 and Example 8. FIG. The left side of FIG. 19 is a photograph of the plants preserved in the preservation device of Comparative Example 8 on the 8th day, and the right side of FIG. 19 is a photograph of the plants preserved in the preservation device of Example 8 on the 8th day.

On the other hand, as shown on the right side of FIG. 19 and the right side of FIG. 20 , the plants preserved in the preservation device of Example 8 were hardly changed from those at the start of the experiment. From this, it can be seen that if the storage device is equipped with the space potential generating device 6, the storage period of the object to be stored 64a can be extended.

<Effect of the voltage adjustment section>

The voltage applied to the electrode portion 2 can be adjusted according to the number of objects to be stored such as fresh flowers and the size of the storage space 64b to be stored by the voltage adjustment unit in the storage device of the fifth embodiment.

When the preservation device of this modification is attached to the upper surface of the coffin, the electrode portion discharges static electricity into the coffin, thereby forming an alternating electric field in the coffin, and the formed alternating electric field is applied to the corpse to preserve the corpse. In this way, the water molecules in the corpse will be irradiated with electromagnetic waves of a specific wavelength, so the cells in the corpse will be activated, thereby preventing the state of the corpse from changing. In addition, if it is stored in the temperature range between -1°C and -5°C below freezing point, bacteria can be suppressed, and the remains can be managed in a good state. Furthermore, if the voltage adjustment unit (see FIG. 3 ) is attached, several corpses can be preserved. Since the number of electrode parts 2 can be increased according to the number of coffins, additional coffins can be added.

Embodiment 6

＜Drying device＞

Next, a drying apparatus according to Embodiment 6 will be described. In the drying apparatus of the sixth aspect, an alternating electric field is formed in the drying chamber, and the object to be dried is dried in the drying chamber in which the alternating electric field is formed. In addition, the drying device of the sixth embodiment is equipped with a space potential generating device, that is, an electric field forming device that forms an alternating electric field.

As shown in FIG. 21 , the drying apparatus according to the sixth embodiment includes a drying chamber 65 , an electrode part 2 , and a voltage applying device 3 . The drying chamber 65 is a demarcation part which delimits the drying space 65b, and the drying space 65b is formed in the drying chamber 65 for drying the to-be-dried object 65a. As the drying chamber 65, for example, a drying chamber having a shelf board 65c can be used. The electrode part 2 is installed in the drying chamber 65 . The voltage applying device 3 forms an alternating electric field in the drying chamber 65 by applying the alternating voltage VL1 (see FIG. 3 ) to the electrode portion 2 . The electrode portion 2 and the voltage applying device 3 constitute a space potential generating device 6 that forms an alternating electric field in the drying chamber 65 .

The drying apparatus of the sixth embodiment may not have the drying chamber 65 . In this case, the drying device composed of only the electrode part 2 and the voltage applying device 3 can be combined with the drying chamber to dry the object to be dried.

When drying the object to be dried, there is a method of forcibly blowing hot air on the object to be dried. However, the problem of this method is that the power consumption is large, the electricity bill is high, the running cost of the drying device is high, and the drying object is discolored due to the high temperature drying.

Another method of drying a to-be-dried object is to rapidly cool a thing containing water, freeze it once, and dry it by sublimating ice. However, although this method improves the quality of the object to be dried after drying, there are problems in that the price of the freeze dryer is very expensive, and the introduction cost of the drying device is high.

Another method of drying the object to be dried is to dehumidify the drying chamber to remove the moisture in the indoor air and to adjust the relative humidity. The advantage of this method is that compared with drying with hot air, it can reduce energy consumption by 50%, and the cells in the dried material are not easily destroyed. However, this drying method has problems that the drying speed is slow and the drying efficiency is low.

That is, with the original drying method, it is difficult to efficiently perform drying while reducing the investment cost and operating cost of the drying apparatus.

At this time, due to the effect of the alternating electric field, the water molecules in the object to be dried 65a are more likely to vibrate and evaporate more easily, and the drying speed is increased. In this way, the electrode unit 2 and the voltage applying device 3 can be introduced and operated at low cost, and the object to be dried 65a in the drying chamber 65 can be dried efficiently.

In addition, the drying device of the sixth embodiment is also the same as the fresh-keeping device of the first embodiment, and is equipped with a space potential generating device 6 composed of an electrode part 2 and a voltage applying device 3, and the voltage applying device 3 is the same as that of the fresh-keeping device of the first embodiment. , with a voltage adjustment unit 41 (refer to FIG. 3 ). In this way, the intensity of the alternating electric field in the drying chamber 65 can be adjusted to the optimum intensity according to the type, quantity and packaging conditions of the objects to be dried 65a, or the temperature or humidity in the drying space 65b. As a result, both the initial investment cost and the long-term operation cost of the storage device can be reduced, the influence range of the alternating electric field can be controlled, and the target space of the alternating electric field can be increased or decreased.

In addition, the object to be dried is not particularly limited. Therefore, using the drying apparatus of the sixth embodiment, red peppers, radishes, pumpkins, potatoes, bellflowers, carrots, oranges, shiitake mushrooms, dried beef, dried persimmons, garlic, coffee, tobacco, dried sardines, yellow croakers, shrimps, Dried fish, cod or sea cucumbers are dried.

The drying chamber 66 is a demarcation part which delimits the drying space 66b, and the drying space 66b is formed in the drying chamber 66 for drying the to-be-dried object 66a. As the drying chamber 66, for example, a drying chamber having a shelf plate 66c can be used.

The drying apparatus of this modification is equipped with the electrode part 2 and the voltage applying apparatus 3 similarly to the drying apparatus of Embodiment 6, and the electrode part 2 and the voltage applying apparatus 3 constitute the space potential generating apparatus 6 . The electrode part 2 and the voltage application device 3 attached to the drying device of this modification can be the same as the electrode part 2 and the voltage application device 3 attached to the fresh-keeping device of the first embodiment, so the detailed description thereof is omitted. .

In the present modification, the electrode unit 2 is attached to the lower surface of the ceiling 66d of the drying chamber 66 . In this way, the time for drying the object to be dried 66a in the drying chamber 66 can be shortened. However, the electrode portion 2 is covered with an insulating material, which is omitted in FIG. 22 .

It is preferable that the electrode part 2 is attached to the center part of the plan view of the drying space 66b formed in the drying chamber 66. FIG. In this way, a uniform alternating electric field can be formed in the drying chamber 66, that is, in the drying space 66b.

In addition, since the power consumption of Example 10 was reduced by 17% compared with that of Comparative Example 10, the power consumption of Example 9 was reduced by 41% compared to that of Comparative Example 9.

Next, a drying device without a space potential generating device was used as a comparative example 11, and a drying device according to a modification of the sixth embodiment equipped with the space potential generating device 6 was used as an example 11.
