Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a fryer for applying a high piezoelectric field to oil to suppress deterioration of the oil.

[0002]

2. Description of the Related Art Conventionally, since it is possible to warm oil by supplying microwaves into an oil tank, an electric heater such as a sheath heater can be omitted. Moreover, it has been considered that by applying microwaves to the oil, the oil does not come into contact with the high temperature part of the electric heater such as the sheathed heater, so that the deterioration of the oil can be suppressed at the same time.

However, subsequent studies have shown that the deterioration of oil is related to the oxidation of food fats and oils such as soybean oil, and the deterioration of oil is sufficiently caused by applying microwaves to the oil as described above. Therefore, there is an early demand for elucidation of a method for coping with oil deterioration.

By the way, although it depends on the kind and amount of foods fried by oil, the amount of oil that deteriorates also depends on the amount of oil used per day, especially in factories producing fried foods. Since there are many oils, it is necessary to change the oil frequently, which not only makes the changing work very time-consuming, but it is also very expensive depending on the type of oil, which is also disadvantageous in terms of cost. In some cases, it has been highly desired to suppress the oil from prematurely deteriorating.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned situation, and an object of the present invention is to provide a fryer in which oil does not deteriorate at an early stage.

[0006]

In order to solve the above-mentioned problems, the present invention provides a high voltage generator for generating a high voltage in the range of 8 kV to 17 kV and is generated by the high voltage generator. A fryer was constructed by providing a plate-shaped electrode to which a high voltage is applied and disposing this electrode in an oil tank to generate a high piezoelectric field. Therefore, when a high piezoelectric field is applied to oil, the action of destroying a large group of water molecules and making the group of water molecules smaller, and the action of instantaneously promoting separation and evaporation (general theory as a change in water in an electric field) ) And to activate steaming, impurities (water content including free fatty acids and emulsifying substances) have a charging property, increase mass, and promote separation and settlement from insulating oil,
The amount of water dissolved in the oil can be extremely suppressed, and the deterioration of the oil can be reliably prevented. In addition, the moisture left in the fried food does not return to the previous state and is reversed and the natural evaporation property decreases,
It delays and weakens the force of molecular assembly (generally characteristic of electric field water), amplifies the feeling of mass and juiciness of fried food, and loses its shape and softens as compared with the case where a high piezoelectric field is not applied.

Since the oil can be activated by providing an object that generates far infrared rays in the oil tank, not only can the oil be made mellow to bring out the umami component of food, but also at a low temperature ( 150 degrees to 16
Even when frying at about 0 degrees, the oil is well drained and can be fried with a firm touch. Moreover, the oil temperature should be low (150
The generation of fatty acid gas can be suppressed as much as possible by frying while maintaining the temperature at about 160 to 160 degrees. Regarding the temperature for frying the oil, it is generally said that the optimum temperature is about 180 degrees (the temperature at which it can be deep-fried),
For example, if you check the flash points of various oils, it is
2 degrees, 225 degrees for olive oil, 249 degrees for corn oil, and 240 degrees for rapeseed oil.
Some of them have temperatures close to the flash point of 0 degree, and the higher the temperature of oil, the more active the thermal decomposition state due to heat, and the more easily gasification occurs. From this,
It is highly desirable to fry at a low temperature even once.

A detection sensor is provided for detecting that discharge is occurring between the high voltage generator and the electrode, and when the detection sensor detects that discharge is occurring, this is notified. Informing means for doing so is provided. For example, when a metal piece or carbonized fried refuse enters the electrode, electric discharge is generated between the high voltage generator and the electrode without generating an electric field.This is detected by the detection sensor. By notifying by the notifying means, it is possible to immediately respond.

The high voltage generator and the electrode are detachably connected, and a detection sensor for detecting the disconnection is provided. When the detection sensor detects the disconnection, A notifying means for notifying the user is provided. With this structure, the electrode side can be cleaned by disconnecting the high voltage generator from the electrode. If the connection between the high voltage generator and the electrodes is not complete after this cleaning, or
For example, it gets caught in the cord that connects the high voltage generator and the electrode.
When the connection between the high voltage generator and the electrode is disconnected for some reason, this can be immediately dealt with by detecting this by the detection sensor and notifying by the notifying means.

A frame is arranged in the oil tank, and the frame is placed in the frame.
Electrode and filter for frying waste located above it
Housing the object between the electrode and the filter.
To form a large number of holes in the object and the electrode,
The hole of the object and the hole of the electrode have the same size and shape.
And so that they are formed at substantially the same position in the vertical direction.
Depending on, the oil and oil dregs that have passed through the pores of the filter
Does not add resistance to the flow.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows a fryer according to the present invention. This fryer comprises a main body 3 consisting of an oil tank 1 for storing oil and a valve 2 at its lower end for opening and closing an outlet, a high voltage generator 4 for generating a high voltage of 10 kV, and a high voltage generator for this high voltage. A plate-shaped electrode 5 to which a high voltage generated by the device 4 is applied is provided as a main component. The high voltage generator 4 has a voltage of 8 kV to 17 kV.
A value other than 10 kV may be set within the range up to. In this case, a variable device such as a slidac capable of changing the voltage value may be incorporated in the circuit for implementation.

By disposing the electrode 5 to which the high voltage is applied in the oil tank 1, a high piezoelectric field is applied in the oil tank 1 to destroy a large group of water molecules as described above and Utilizing the action of making it small and the action of promoting separation and evaporation instantly, steamification is activated, and impurities (water containing free fatty acids and emulsifying substances) become a charging property, increasing the mass and It is separated and settled from the oil, and the settled impurities are discharged to the outside of the oil tank 1 by manually operating the cock of the valve 2.

As shown in FIG. 3, the electrode 5 is made of stainless steel having numerous holes 5A. The electrode 5 is housed in a stainless steel frame 7 having a Teflon insulator on the bottom. The frame 7 is made of an annular plate material having a substantially L-shaped cross section. Further, a plate-shaped ceramic far-infrared sheet 8 in which a large number of holes 8A ... Is formed is arranged on the upper surface of the electrode 5, and a stainless steel frying dust filter 9 is arranged on the upper surface of the far-infrared sheet 8. Are arranged. The far infrared ray sheet 8 and the filter 9 are also housed in the frame 7. The frame 7 in which various members are housed in this way is mounted and supported on the support member 35 as will be described later, and is fixed in the oil tank 1 by using a bolt or the like, or fixed by an engaging means. Good.
By arranging the far-infrared sheet 8 as described above, the oil is well drained even when the temperature in the oil tank 1 is set to a low temperature (about 150 to 160 degrees), and the oil can be deep-fried.

By forming the far-infrared sheet 8 in the form of a plate, the vertical arrangement space can be kept small, and the space for frying the oil in the oil tank 1 does not decrease significantly. However, it is not limited to the plate-shaped one. Further, since the far infrared ray sheet 8 is made of ceramics and has excellent insulation properties, it can be made to function as an insulating member simply by placing it on the electrode 5, and a special surface for the electrode 5 can be provided. The insulating member can be eliminated. Further, the far-infrared ray sheet 8 may be made of ceramics, or may be made of natural stone or artificial stone that emits far-infrared rays, or one obtained by processing charcoal.

The mounting structure of the filter 9, the far infrared ray sheet 8 and the electrode 5 will be described. As shown in FIG. 3, L fixed to the casing 6 forming the oil tank 1 is used.
The frame 7 is mounted and supported on the mold supporting member 35. The first insulating material 3 made of Teflon is formed on the inner surface of the frame 7.
6 is attached, a second insulating material 37 made of Teflon or a ceramic that generates far infrared rays is fixed to the inner lower end, and the electrode 5 is placed on the second insulating material 37. Filter 9 through 3 insulation 38
Is placed. The far-infrared sheet 8 is placed and supported on the upper surface of the electrode 5. By opening a vertical gap between the filter 9 and the far-infrared ray sheet 8 by the third insulating material 38, oil or oil debris that has passed through the holes 9A of the filter 9 is separated from the filter 9 and the far-infrared ray sheet 8. It is designed to be able to move smoothly without staying in between. Also, each hole 9A of the filter 9
Is set to a size of about 6 mm, and the holes 8A of the far-infrared sheet 8 and the holes 5A of the electrodes 5 are set to be larger than the holes 9A (actually, about 10 mm to 15 mm). The oil residue that has passed through the hole 9A is taken as the hole 8
It can be surely moved downward from A and 5A. Moreover, the hole 8A of the far infrared ray sheet 8 and the hole 5A of the electrode 5 have the same size and shape (a circle in the figure, but are rectangular, rhombic, elliptical, etc.) and at substantially the same position in the vertical direction. In addition, since the far-infrared sheet 8 is made of an insulating material, the far-infrared sheet 8 can be superposed on the electrode 5 without requiring a spacer or the like as an insulating material. Not only does it not give a resistance to the flow of oil and oil dregs that have passed through 9A, but an insulating material that also serves as a spacer is not required, which is advantageous in terms of cost and has the advantage that the vertical dimension can be kept small. is there. The hole 9 of the filter 9
The size and shape of A, the size and shape of the hole 8A of the far infrared ray sheet 8, and the size and shape of the hole 5A of the electrode 5 are not limited to those shown.

As shown in FIG. 2, a cord 10 is connected to the electrode 5, and a high voltage plug 11 is attached to the tip of the cord 10. The high-pressure plug 11 is covered with an insulating cover 12 made of Teflon that is less likely to deteriorate with respect to moisture and high temperature. Code 1 from the high voltage generator 4
A high-voltage socket 14 into which the high-voltage plug 11 can be inserted is attached to the tip of the connector 3, and the high-voltage socket 14 is covered with an insulating cover 15 made of Teflon as described above. Therefore, by removing the high-voltage socket 14 from the high-voltage plug 11, the cleaning work on the electrode 5 side can be easily performed. Then, a limit switch 16 as a detection sensor for detecting disconnection between the high-voltage plug 11 and the high-voltage socket 14 is attached to the lower surface of the insulating cover 15, and the high-voltage socket 14 is inserted into the high-voltage plug 11. As a result, as shown by the chain double-dashed line, the tip portion 16A of the limit switch 16 contacts the contact portion 17 provided in the insulating cover 12, and the limit switch 16 is in the ON state and is in the connection state. Is detected and the information is input to an alarm circuit 29 described later. Therefore, when the limit switch 16 is in the OFF state, it is detected that the connection is disconnected or the insertion after cleaning is incomplete, and the information is input to the alarm circuit 29 described later, and the alarm device described later is detected. (Informing means), that is, the alarm buzzer 2

And a choke coil 22 for smoothing the components. The high voltage transformer 18 is covered with a metal case to take safety measures. Then, the secondary side of the high-voltage transformer 18 is short-circuited by using the resistor 23 to close one pole, and the high voltage weak current (1
By supplying a voltage of 0 kV, 20 mA), the current flowing when a high voltage is applied between the electrode 5 and the ground is released from the ground. Due to this phenomenon, the current flowing through the cord 13 is reduced, and this is detected by the leak sensor 25, which will be described later, to notify it. Reference numeral 24 shown in the figure is a power source display lamp, which is lit when the power source is on.

The cord 13 is provided with a leak sensor 25 as a detection sensor for detecting that electric discharge is occurring between the high voltage generator 4 and the electrode 5, and a detection signal from the leak sensor 25 is provided. An amplifier 26 for amplification is provided, and an alarm buzzer 27 as an informing means and an alarm circuit 29 for operating an alarm lamp 28A are provided based on the detection information from the amplifier 26. Therefore, when the high voltage generator 4 and the electrode 5 are discharged, the leak sensor 25 detects the discharge and sounds the alarm buzzer 27, and the alarm lamp 28.
A is turned on to notify. The leak sensor 25 actually detects the current value flowing through the cord 13, and when the current value falls below a set value, discharge is performed between the high voltage generator 4 and the electrode 5. It is detected as being broken.

Further, the limit switch 16 and the alarm circuit 29 are connected via a cord 30, and the detection signal from the limit switch 16 is input to the alarm circuit 29, whereby the alarm buzzer 27 and the limit The alarm lamp 28B for the switch is activated. That is, when the OFF signal from the limit switch 16 is input to the alarm circuit 29, the alarm buzzer 27 is sounded and the alarm lamp 28B is turned on.

Further, a non-contact type detection sensor 31 for detecting moisture is provided at the lower end of the oil tank 1, and the detection sensor 31 is provided.
And an amplifier 32 for amplifying the detection signal from the sensor 31 are connected via a cord 33, and the amplifier 32 and the alarm circuit 29 are connected via a cord. When the detection sensor 31 detects moisture, this detection signal is amplified by the amplifier 32 and then input to the alarm circuit 29 to sound the alarm buzzer 27 and turn on the alarm lamp 28C. Reference numeral 34 shown in the figure is a power supply circuit for supplying power from the commercial AC power supply to the alarm circuit 25.

In the above embodiment, three alarm lamps 28 are provided.
Although the common alarm buzzer 27 is used for A, 28B, and 28C, the cost can be reduced, but, for example, three types of alarm buzzers that emit different sounds may be provided and implemented. Further, in the above-described embodiment, the alarm buzzer and the alarm lamp are used as the notification means, but instead of the alarm lamp, a display device for displaying the alarm content in characters or pictures may be provided. It is also possible to provide a voice device for notifying the content of the alarm by voice, and the specific configuration of the notifying means can be freely changed.
