Description

  In the present invention, ice produced by cooling supplied salt water is made into fine ice with a scraper, and the fine ice and the salt water are mixed to produce a salt water-mixed sherbet-like ice water. The present invention relates to a manufacturing method and a manufacturing apparatus of salt water mixed sherbet ice.

  Conventionally, in order to maintain the freshness of saltwater fish, the saltwater fish is generally cooled with massive ice. However, with ordinary massive ice, the marine fish can be damaged by massive ice due to vibration during sea transportation and land transportation, and the massive ice. In recent years, for example, as disclosed in Patent Document 1, ice generated by cooling salt water is removed from a scraper (scraper or scraper blade). It is also said that the seawater fish is cooled with the sherbet-like or powder snow-like ice.

Japanese Patent Laid-Open No. 2003-42611 (FIGS. 1 to 3 and description thereof)

  In the conventional sherbet-shaped or powder-snow ice making machine shown in Patent Document 1, since the ice take-out port is provided on the uppermost upper part of the ice making unit, the sherbet pushed out to the ice take-out port by the auger screw It is understood that ice in the form of powder or snow powder is taken out from the ice outlet and used as it is, but in order to maintain the freshness of seawater fish for a long time, salt water mixed sherbet ice mixed with a large amount of salt water, For example, the volume ratio of the sherbet-like ice to the mixed water of salt water and sherbet-like ice (hereinafter abbreviated as “sorbet concentration”) is preferably maintained at about 30%. If the sherbet concentration exceeds 50%, 70% or 80%, when the sherbet-like ice melts, the amount of fresh water increases, the salinity decreases significantly, and the freshness of the seawater fish is maintained for a long time. Is difficult. When the sherbet concentration is 90% or 100% (powder snow), an air layer is formed between the sherbet-like ice particles and the epidermis of the seawater fish even if the particle diameter of the sherbet-like ice is 0.1 mm, for example. This is undesirable in maintaining the freshness of saltwater fish. Therefore, the so-called “salt water mixed sherbet ice” in which a sufficient amount of salt water having a sherbet concentration of about 30% is mixed is used to improve the adhesion between the salt water mixed sherbet ice and the seawater fish, Even when melted, a salt water mixed sherbet-like ice having a sherbet concentration of about 30%, which is a mixed water of salt water and sherbet-like ice, which is a sufficient amount so that the salt concentration does not decrease so much is preferable.

  In addition, the salinity of seawater inhabited by seawater fish is around 3.5% in the waters near Japan, but there is a certain range depending on the region. In addition, fish with a relatively large fish body should be cooled and stored at a lower temperature (for example, −2.5 ° C.), and fish with a smaller fish body at a higher temperature (for example, −1.0 ° C.), The freshness and deliciousness can be maintained even when stored for a long time. That is, the temperature required for the saltwater mixed sherbet-like ice differs depending on the size of the saltwater fish body and the type of fish. In producing this salt water mixed sherbet-like ice, it is the salinity concentration that influences the temperature. If it is fresh water, it freezes at 0 ° C, but the solidification temperature when the salinity is about 3.5% like seawater is about -2.1 ° C, and the solidification temperature when the salinity is about 2%. Is about −1.0 ° C. Thus, the higher the salt concentration, the lower the temperature. Therefore, when producing a saltwater mixed sherbet-like ice at a relatively low temperature as in the case of using a saltwater-mixed sherbet-like ice production method and apparatus for cooling a large saltwater fish, Thus, when producing salt water mixed sherbet ice having a relatively high temperature, it is convenient to be able to adjust the temperature of the salt water mixed sherbet ice to be manufactured so that it can be applied in any case. It is preferable that the salt concentration of the salt water mixed sherbet ice can be adjusted to an appropriate value depending on the application.

  In addition, when used on medium-sized ships, large ships, fish markets, etc., it is considered that the amount of use is large and the amount of use cannot be sufficiently satisfied, and it is also attempted to produce a large amount of sorbet-like or powdered snow-like ice. For example, since it is necessary to increase the amount of sorbet-shaped or powdered snow-like ice produced per unit time, if the amount taken out at the ice outlet is less than the amount produced, the sorbet-shaped or powdered-snowy ice is removed from the ice. It is conceivable that the ice making device becomes overloaded when the mouth is clogged, and as a result, the sherbet-like or powdered snow-like ice clogged in the ice take-out port is solidified into a lump and falls into a locked state where the ice making device does not operate. Therefore, it is desirable to prevent the overload state from falling into the locked state even when a relatively large amount of sherbet-like ice is produced.

  The present invention has been made in view of the above-described circumstances, and is mainly intended to produce a salt-mixed sherbet-like ice having a stable concentration suitable for the cold storage of seawater fish, rather than merely producing a sherbet-like ice. In the case of producing a relatively large amount of sherbet-like ice for the second purpose of producing salt water-mixed sherbet-like ice having a salt concentration arbitrarily selected according to the size of the seawater fish, the fish species, etc. The third object is to prevent the ice making device from falling into the locked state from the overload state even when producing salt water mixed sherbet-like ice having a relatively low salinity.

Further, the flow rate of the output water of the salinity concentration adjusting device 260a adjusted to a constant salinity concentration is made constant so that the control to the selected predetermined concentration is stabilized.

  Next, the operation will be described with reference to FIG.

  A salt water having a salt concentration arbitrarily selected and set by the salt concentration setter 261 (for example, 2%, 3%, 3.5%, etc., set by the user) is transferred to the seawater 23 in the salt concentration adjustment tank 22. It is generated from fresh water 24. The salt concentration of the salt water in the salt concentration adjustment tank 22 is detected by a salt concentration sensor 26. Depending on the difference between the output of the salinity concentration sensor 26 and the salinity concentration arbitrarily selected and set by the salinity concentration setting unit 261, the salt water in the salinity concentration adjusting tank 22 is arbitrarily changed by the salinity concentration setting unit 261. The opening of each of the fresh water amount adjusting valve 25a and the seawater amount adjusting valve 25b is automatically adjusted by the output of the salinity concentration setting device 261 so that the salt water with the salt concentration selected and set to At least one amount of the fresh water 24 is controlled to generate salt water having the set salinity (hereinafter referred to as “predetermined salinity”), and the generated salt water having the predetermined salinity is chiller or the like ( Depending on a predetermined temperature (for example, a relatively low temperature between the ambient temperature and the temperature of the salt water mixed sherbet ice) or the salt water mixed sherbet. Slightly higher temperature than Jo ice temperature, is cooled, for example, 2 ° C.), are stored in the cold sea water storage means 27, such as the next stage of the cold sea water storage tank.

  The salt water is stored in the ice storage tank 14 via the cold seawater supply control valve 28 and is fixed to a predetermined salt concentration and a predetermined temperature stored in the cold seawater storage means 27.

  The salt water having a predetermined constant salinity concentration and a predetermined constant temperature stored in the ice storage tank 14 is introduced into the salt water side passage 1 b of the ice making device (also called an ice generator) 1 by the circulation pump 11. A refrigerant liquid of about −12 ° C. supplied from the refrigerator 4 flows into the refrigerant side passage (evaporator) 1 a of the ice making device 1.

  The salt water having the predetermined salt concentration and the predetermined temperature flows through the salt water side passage 1b of the ice making device 1, the salt water contacts the inner peripheral surface (heat transfer surface) of the inner cylinder 1e of the ice making device 1, and the contacted salt water is a refrigerant. Ice is generated on the inner peripheral surface of the inner cylinder 1e by being cooled by the refrigerant in the side passage (evaporator) 1a.

  The ice generated on the inner peripheral surface of the inner cylinder 1e is scraped by a scraper (scraping blade) 1c on the outer periphery of the rotating cylinder 1f that is driven to rotate by a drive source (rotating cylinder driving motor) 2 of the ice making device. .

  The ice scraped off by the scraper 1c is about 0.1 mm in size, and is mixed with the salt water in the salt water side passage 1b in the salt water side passage 1b of the ice making device 1 and scattered almost uniformly in the salt water. Sherbet shape. That is, it becomes salt water mixed sherbet ice.

  The salt water mixed sherbet ice produced in the salt water side passage 1 b of the ice making device 1 is pushed out of the salt water side passage 1 b by the circulation pump 11, passes through the pipe 13, and is stored in the ice storage tank 14.

  The salt water mixed sherbet ice 143 stored in the ice storage tank 14 is returned to the salt water side passage 1b of the ice making device 1 by the circulation pump 11, and ice is generated on the inner peripheral surface of the inner cylinder 1e in the same manner as described above. The scraper 1c is scraped off to generate salt water mixed sherbet-like ice with many ice particles in the salt water side passage 1b.

  The salt water mixed sherbet ice with a lot of ice particles is further pushed out of the salt water side passage 1b by the circulation pump 11, passed through the pipe 13, and stored in the ice storage tank 14 as described above.

  The aforementioned salt water mixed sherbet-shaped ice is returned from the ice storage tank 14 to the salt water side passage 1b, salt water mixed sherbet ice with more ice particles in the salt water side passage 1b is generated, and the salt water side passage 1b The cycle of recirculation of salt water mixed sherbet ice with more ice particles to the ice storage tank 14 is repeated many times, and a predetermined amount of salt water mixed sherbet ice 143 having a predetermined sherbet concentration is stored in the ice storage tank 14. The sherbet concentration refers to the ratio of the amount of ice particles (also referred to as ice amount) to the amount of salt water mixed sherbet ice.

  As described above, the salt water mixing sherbet-like ice 143 having a predetermined sherbet concentration is not obtained only by passing the salt water once through the ice making device 1, but the above reflux is repeated many times over a long time. A salt water mixed sherbet ice 143 having a predetermined sherbet concentration is gradually generated.

  For example, when the salt water mixed sherbet-like ice 143 having a predetermined sherbet concentration of 30% of 10 tons is generated, the reflux is repeatedly generated gradually over a period of about 10 hours. Therefore, since a large amount of ice is not generated in the salt water side passage 1b of the ice making device 1 in a short time, the ice making device becomes inoperable due to agglomeration due to solidification of the sherbet-like ice as compared with the above-described conventional methods and devices ( The rotating cylinder 1f stops rotating) and almost never falls into a locked state.

  By repeating the reflux many times, the sherbet concentration of the salt water mixed sherbet-like ice gradually increases and its viscosity gradually increases. The sherbet concentration of the salt water mixed sherbet-like ice gradually increases, and the viscosity thereof gradually increases, which means that the ice making device 1 is likely to fall into an overload state or a state that tends to fall into a locked state. It means to go. Therefore, in the first embodiment of the present invention, as described above, it is almost impossible to fall into the locked state. However, for example, in the event that a sudden drop in the ambient temperature due to a sudden change in weather or a repeated short interruption occurs, for example. If a countermeasure is taken on the assumption of falling into a locked state, a more reliable method for producing salt water mixed sherbet ice and a device for producing salt water mixed sherbet ice will be realized.

  Further, if the sherbet concentration of the salt water mixed sherbet-like ice becomes too high, for example, if the sherbet concentration exceeds 50%, for example, 60%, 70%, and 80%, the viscosity of the salt water mixed sherbet ice 143 becomes viscous. Not only makes it difficult for the circulation pump 11 to push the ice making device 1 into the salt water side passage 1b, but also causes the ice making device drive source (rotary cylindrical drive motor) 2 to have high loads and overloads. Then it finally stops. Accordingly, when a salt water mixed sherbet ice having a proper sherbet concentration, for example, a salt water mixed sherbet ice having a sherbet concentration of 30% is generated, the refrigerator is stopped and ice making is stopped so that no more sherbet ice can be produced. . In this case, the determination that the proper sherbet concentration is achieved is, for example, the temperature of the salt water mixed sherbet ice measured by the temperature sensors 10 and 29b. That is, when the temperature of the salt water mixed sherbet ice reaches a specified temperature, the refrigerator 4 is stopped. Thus, by monitoring the temperature of the salt water mixed sherbet-like ice, by controlling the operation of the refrigerator 4, it is possible to prevent the ice making device 1 from being overloaded and stopped due to the sherbet concentration becoming too high.

  The specified temperature depends on the salinity of seawater. For example, when the salt concentration is 3.5%, it is -2.1 ° C, and when it is 2%, it is -1.1 ° C. -2.1 ° C <-1.1 ° C. By the way, the salinity of seawater varies depending on the environment. For example, salinity is low immediately after heavy rain or near the river mouth. Therefore, for example, as a result of using seawater collected immediately after heavy rain or near the estuary as input seawater of the salinity concentration adjusting device 260a, the salinity concentration of the input seawater may be lower than the salinity concentration selected and set by the salinity concentration setting device 261. Arise. When the salinity concentration of the input seawater is lower than the salinity concentration selected and set by the salinity concentration setter 261, the specified temperature is raised according to the detection value by the salinity concentration sensor 26, and when the appropriate sherbet concentration is reached, the refrigerator 4 must be stopped promptly. However, even if the salt concentration is lowered and the specified temperature is raised, it is not always in theory, and salt water mixed sherbet-like ice having a concentration higher than the theoretically predicted sherbet concentration is generated, and the salt water mixed sherbet is generated. The iced ice becomes so viscous that it becomes difficult to push water through the circulation pump 11 into the salt water side passage 1b of the ice making device 1, and the ice making device drive source (rotary cylindrical drive motor) 2 is stopped due to high load. There was a case. Further, when the sherbet concentration is further increased, the ice in the salt water mixed sherbet-like ice in the salt water side passage 1b of the ice making device 1 grows and its volume increases, so that the ice making device 1 main body may be damaged.

  Therefore, in the first embodiment of the present invention, first, the input seawater 23 repeats the above reflux from the salt water adjusted to the constant salt concentration selected and set by the above-described salt concentration adjusting device 260a, and then, the seawater 23 has a predetermined constant value. Produces salt-mixed salt water mixed sherbet ice. Further, an ice making device load detection sensor (current sensor) 3 for detecting a load state of a driving source (rotating cylinder driving motor) 2 for driving the rotating cylinder 1f of the salt water ice making device 1 is provided, and the load of the driving source 2 is determined by the output thereof. Rises, the pump control device (inverter) 11a is automatically controlled to increase the output of the circulation pump 11, and the discharge pressure of the circulation pump 11 is increased. From the salt water side passage 1b at the initial stage of the solidification of the sherbet ice. Forcible extrusion to the pipe 13 prevents the ice making device 1 from falling into an overloaded state or a locked state. In addition, when the load of the ice making apparatus 1 becomes more than a predetermined value, it may be notified by a buzzer, a voice or the like, and when the notification is given, the output of the circulation pump 11 may be increased manually. However, in the case of manual operation, although it is slightly cheaper, there may be a case where the timing of increasing the output of the circulation pump 11 is delayed or the amount of increase of the output of the circulation pump 11 is small. It is preferable to control automatically so that this does not occur.

  Further, the cold seawater supply control valve 28 is closed under a state where the reflux is repeated many times. On the other hand, under the state where the reflux is repeated many times, the temperature of the mixed water of the sherbet-like ice and the salt water in the salt water side passage 1b is 0 ° C. or less (for example, when the salt concentration is 2%). About -1.1 ° C, and about -2.1 ° C when the salinity is 3%). In the first embodiment, the temperature of the cold seawater stored in the cold seawater storage means (cold seawater storage tank) 27 is about 2 ° C., for example.

  Therefore, in Embodiment 1 of the present invention, in addition to the automatic control of the circulation pump 11 output by the output of the ice making device load detection sensor 3, the cold seawater supply control valve 28 is automatically set by the output of the ice making device load detection sensor 3. The cold seawater of the cold seawater storage means 27 having a temperature higher than the temperature of the mixed water of sherbet-like ice and saltwater in the salt water side passage 1b is supplied into the salt water side passage 1b via the circulation pump 11. The solidification of the sherbet-like ice in the salt water side passage 1b is suppressed.

The salt water supplied to the ice making device 1 is predetermined. Since it is a manufacturing apparatus of salt water mixing sherbet-like ice provided with a salt concentration adjusting device 260a that adjusts to a constant salt concentration, even when a relatively large amount of sherbet-like ice is manufactured, it is difficult to fall from the overload state to the locked state. However, it is possible to produce a salt-mixed sherbet-like ice with a stable concentration suitable for refrigerated storage of seawater fish, rather than just making a sherbet-like ice, but for some reason such as a sudden change in environmental temperature, 1. When the load of the ice making device 1 exceeds a predetermined value, the refrigeration cycle of the compressor 5, the condenser 6 and the evaporator (refrigerant side passage) 1a for cooling the inner cylinder 1e of the ice making device 1 is well-known.

A fourth embodiment of the present invention will be described below with reference to FIG. FIG. 2 is a diagram showing an example of the overall system configuration of the apparatus for producing salt water-mixed sherbet-like ice for carrying out the method for producing salt-water mixed sherbet-like ice of the present invention, and illustrates the case where seawater is used as salt water. . The same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals, the description of the same or corresponding parts as those in FIG. 1 is omitted, and different from the first to third embodiments of the present invention. The following explains the subject.

  As described above, according to the first embodiment of the present invention, the ice produced by cooling the salt water supplied in the ice making device 1 is made into fine ice by the scraper 1b and mixed with the salt water by mixing the fine ice and the salt water. Sherbet-like ice is made, and the salt water mixed sherbet ice is fed from the ice making device 1 to the ice storage tank 14 to store the salt water mixed sherbet ice in the ice storage tank 14, and the salt water stored in the ice storage tank 14 is stored. Salt water mixed sherbet ice for storing a predetermined amount of the salt water mixed sherbet ice at a predetermined sherbet concentration and a predetermined low temperature in the ice storage tank 14 while recirculating the mixed sherbet ice 143 from the ice storage tank 14 to the ice making device 1 a plurality of times. The salt making water adjusted to a predetermined constant salt concentration is supplied to the ice making device. The salt water mixing sherbet-like ice is produced, and the ice produced by cooling the salt water supplied in the ice making device 1 is made into fine ice by the scraper 1b, and the salt water is mixed by mixing the fine ice and the salt water. Sherbet-like ice is made, and the salt water mixed sherbet ice is fed from the ice making device 1 to the ice storage tank 14 to store the salt water mixed sherbet ice in the ice storage tank 14, and the salt water stored in the ice storage tank 14 is stored. Salt water mixed sherbet ice for storing a predetermined amount of the salt water mixed sherbet ice at a predetermined sherbet concentration and a predetermined low temperature in the ice storage tank 14 while recirculating the mixed sherbet ice 143 from the ice storage tank 14 to the ice making device 1 a plurality of times. The salt water supplied to the ice making device 1 is predetermined. Since it is a manufacturing apparatus of salt water mixing sherbet-like ice provided with a salt concentration adjusting device 260a that adjusts to a constant salt concentration, even when a relatively large amount of sherbet-like ice is manufactured, it is difficult to fall from the overload state to the locked state. However, it is possible to produce a salt-mixed sherbet-like ice with a stable concentration suitable for refrigerated storage of seawater fish, rather than just making a sherbet-like ice, but for some reason such as a sudden change in environmental temperature, First, when the load of the ice making device 1 exceeds a predetermined value, the fourth embodiment exemplifies a method and an example of a device for lowering the freezing point in the ice making device 1 by introducing high-concentration salt water.

  In salt water, the freezing point decreases as the salinity increases. For example, when the salinity of ordinary seawater is 3.5%, the freezing point is −2.1 ° C., and when the salinity is 2.5%, the freezing point is −1.4 ° C. If the sherbet concentration increases and the viscosity increases, if salt water with a high salt concentration is added to it, the freezing point decreases, a part of the sherbet is melted, the viscosity is decreased, and the salt water mixed sherbet ice is added. It can flow smoothly.

  Specifically, as shown in FIG. 2, a bypass passage 170 that bypasses the ice storage tank 14 is provided between the ice making device 1 and the ice storage tank 14, and the bypass passage 170 has a high salinity concentration such as a high salt concentration seawater tank. A normal room temperature salt water storage means 17 storing salt water, and a first valve 18 and a second valve 20 located upstream and downstream of the high concentration salt water storage means 17 are provided.

  When the output of the ice making device load detection sensor (current sensor) 3 increases to a level at which it is judged that the sherbet-like ice has solidified in the salt water side passage 1b of the ice making device 1 and starts to become a lump, that is, the rotation of the ice making device 1 When the load of the drive source (rotating cylinder drive motor) 2 for driving the cylinder 1f increases to a load at which it is determined that the sherbet-like ice has solidified in the salt water side passage 1b of the ice making device 1 and begins to become a lump, the ice making device load detection The valves 21 and 19 to the ice storage tank 14 are automatically closed by the output of the sensor (current sensor) 3, and the first and second valves 18 and 20 upstream and downstream of the salt water storage means 17 are automatically opened. Salt water with high salinity is supplied from the salt water storage means 17 into the salt water side passage 1 b of the ice making device 1 by the circulation pump 11. When salt water having a high salinity is supplied into the salt water side passage 1b of the ice making device 1, the sherbet-like ice that has solidified in the salt water side passage 1b and has started to become a lump can be melted. In particular, as in the first embodiment described above, salt water in the cold seawater storage means (cold seawater storage tank) 27 adjusted to, for example, a salt concentration of 2% and a temperature of 2 ° C. is used as the salt water side passage 1b of the ice making device 1. Compared to the case of supplying water into the inside, for example, normal seawater can be supplied as it is (with a salinity of 3.5% or more) or a salt water with a higher salinity, and the salt water temperature in the salt water storage means 17 is Since the temperature of the indoor environment (for example, 15 ° C. to 25 ° C.) where the storage means 17 is installed is high, the sherbet-like ice that has solidified in the salt water side passage 1b and has started to become a lump is more effectively obtained. Can be melted. Note that the high salinity seawater in the saltwater storage means 17 is higher than the normal seawater salinity of 3.4%, for example, preferably 6% or more. The circulation time of the high concentration salt water from the salt water storage means 17 is preferably 1 minute or longer.

  In this case, when the output of the circulation pump 11 is also increased by the output of the ice making device load detection sensor (current sensor) 3 as in the first embodiment, the circulation pump 11 begins to solidify and become agglomerated in the salt water side passage 1b. Since the sherbet-shaped ice is forcibly sent out of the salt water side passage 1b while melting, it is more effective and can be quickly restored to the steady operation load state.

  In addition, the valves 21 and 19 to the ice storage tank 14 are automatically closed by the output of the ice making device load detection sensor (current sensor) 3, and the first and second valves 18 and 18 upstream and downstream of the salt water storage means 17. Instead of automatically opening 20, the output of the ice making device load detection sensor (current sensor) 3 increases to a level at which it is determined that the sherbet-like ice has solidified in the salt water side passage 1 b of the ice making device 1 and has started to become a lump. Then, for example, a notification means such as a buzzer notifies that fact, and based on this notification, the person artificially closes the valves 21 and 19 to the ice storage tank 14, and upstream and downstream of the salt water storage means 17. Even if the first and second valves 18 and 20 are opened, the same effect is obtained. However, in the case of manual operation, the device cost is slightly low, but the timing for opening / closing each of the valves 21, 19, 18, 20 may be delayed or the opening / closing amount may be inappropriate. It is preferable to automatically perform opening / closing control so that this does not occur.

  In the fourth embodiment of the present invention, ice produced by cooling the salt water supplied in the ice making device 1 is made into fine ice by the scraper 1b, and the salt water mixed sherbet ice is formed by mixing the fine ice and the salt water. The salt water mixed sherbet ice is fed from the ice making device 1 to the ice storage tank 14 to store the salt water mixed sherbet ice in the ice storage tank 14, and the salt water mixed sherbet shape stored in the ice storage tank 14 is prepared. An apparatus for producing salt water-mixed sherbet-like ice that stores a predetermined amount of the salt-water-mixed sherbet-like ice at a predetermined sherbet concentration and a predetermined low temperature in the ice-storage tank 14 while recirculating the ice 143 from the ice storage tank 14 to the ice making device 1 a plurality of times. In the process of manufacturing the salt water mixed sherbet ice, A load state detection means 3 for detecting a load state, and a high-concentration salt water storage means 17 for storing a high-concentration salt water having a salt concentration higher than that of the mixed water in the ice-making apparatus 1, and the ice making device 1 has a predetermined load. When the load state detection unit 3 detects that the salt concentration has exceeded, the high concentration salt water of the high concentration salt water storage unit 17 is a salt water mixed sherbet-like ice making device supplied into the ice making device 1, and the salt water side The sherbet-like ice that has solidified in the passage 1b and has started to become clumpy can be melted more effectively, and the heat shock and heat of the ice making device 1 as in the case of the second and third embodiments described above can be obtained. There is no stress.

  In addition, since the high-concentration salt water storage unit is a salt water-mixing sherbet-like ice making apparatus, the salt concentration is adjusted to 2% and the temperature is set to 2 ° C., for example, as in the first embodiment. Compared to the case where the salt water in the cold sea water storage means (cold sea water storage tank) 27 is supplied into the salt water side passage 1b of the ice making device 1, for example, normal sea water as it is (salt concentration of 3.5% or more) or higher Salt water with a salt concentration can be supplied, and the salt water temperature in the salt water storage means 17 is the temperature of the indoor environment (for example, 15 ° C. to 25 ° C.) in which the salt water storage means 17 is installed. Therefore, the sherbet-like ice that has solidified in the salt water-side passage 1b and has started to become a lump can be melted more effectively.

  When the load state detection unit 3 detects that the ice making device 1 has exceeded a predetermined load, the high-concentration salt water storage unit 17 is connected to the ice making device 1 by the output of the load state detection unit 3. The high-concentration salt water stored in the high-concentration salt water storage means is an apparatus for producing salt water-mixed sherbet-like ice supplied into the ice making device 1 so that it does not easily fall into the locked state from the overload state in a short time. To do.

  In addition, when the high-concentration salt water storage unit 17 is provided in the bypass passage 170 and the load state detection unit 3 detects that the ice making device 1 has exceeded a predetermined load, the temperature is higher than the mixed water in the ice making device 1. Since the high-concentration salt water having a high concentration is a salt water-mixed sherbet-like ice producing apparatus supplied from the bypass passage 170 to the ice making device 1, the sherbet-like ice that has solidified in the salt water-side passage 1b and has started to become a lump is further added. Can be dissolved effectively.

The salt water supplied to the ice making device 1 is predetermined. Since it is a manufacturing apparatus of salt water mixing sherbet-like ice provided with a salt concentration adjusting device 260a that adjusts to a constant salt concentration, even when a relatively large amount of sherbet-like ice is manufactured, it is difficult to fall from the overload state to the locked state. However, it is possible to produce a salt-mixed sherbet-like ice with a stable concentration suitable for refrigerated storage of seawater fish, rather than just making a sherbet-like ice, but for some reason such as a sudden change in environmental temperature, First, when the load of the ice making device 1 exceeds a predetermined value, the fifth embodiment is an example of a method and device for lowering the freezing point in the ice making device 1 by introducing high-concentration salt water.

In a steady state, the portable high-concentration salt water storage means 17 is removed from the bypass passage 170, and there is no salt water storage means 17 in the vicinity of the ice making device 1, so that the space can be effectively used.

The salt making water adjusted to a predetermined constant salt concentration is supplied to the ice making device. The salt water mixing sherbet-like ice is produced, and the ice produced by cooling the salt water supplied in the ice making device 1 is made into fine ice by the scraper 1b, and the salt water is mixed by mixing the fine ice and the salt water.

FIG. 6 is a diagram showing an example of the overall system configuration of a production apparatus for salt water mixed sherbet ice that implements the method for producing salt water mixed sherbet ice of the present invention, and illustrates the case where seawater is used as salt water. . The same or corresponding parts as those in FIGS. 1 to 5 are denoted by the same reference numerals, and the description of the same or corresponding parts as those in FIGS. The points different from ˜8 will be mainly described below.

  As described above, according to the first embodiment of the present invention, the ice produced by cooling the salt water supplied in the ice making device 1 is made into fine ice by the scraper 1b and mixed with the salt water by mixing the fine ice and the salt water. Sherbet-like ice is made, and the salt water mixed sherbet ice is fed from the ice making device 1 to the ice storage tank 14 to store the salt water mixed sherbet ice in the ice storage tank 14, and the salt water stored in the ice storage tank 14 is stored.

Even if a person artificially adjusts the fluid resistance of the fluid resistance adjusting means 33 so as to reduce the fluid resistance, the same effect can be obtained. However, in the case of manual operation, the cost of the apparatus is slightly reduced, but the timing for adjusting the fluid resistance of the fluid resistance adjusting means 33 to be small may be delayed, or the adjustment amount may not be appropriate. In order to prevent this from occurring, it is preferable that the fluid resistance of the fluid resistance adjusting means 33 is automatically adjusted to be small.

FIG. 9 is a diagram showing an example of the overall system configuration of a production apparatus for salt water-mixed sherbet-like ice for carrying out the method for producing salt-water mixed sherbet-like ice of the present invention, and illustrates the case where seawater is used as the salt water. . The same or equivalent parts as those in FIGS. 1 to 8 are given the same reference numerals, and the same or equivalent parts as those in FIGS. 1 to 8 are not described. Embodiment 1 of the invention described above A description will be given below mainly of points different from ˜11.

  In the twelfth embodiment of the present invention, as shown in FIG. 9, in the cold seawater storage means (cold seawater storage tank) 27, normal seawater (salinity concentration around 3.5%) is kept at 2 ° C., for example. The cold seawater stored in the cold seawater storage means 27 is stored in a predetermined amount in the ice storage tank 14, and the cold seawater is stored in the ice storage tank 14 in the same manner as in the first to tenth embodiments. The seawater is repeatedly recirculated to the ice making device 1 by a circulation pump 11 several times to gradually generate salt water mixed sherbet ice, and salt water mixed sherbet ice having a predetermined temperature, a predetermined salt concentration, and a predetermined sherbet concentration is supplied to the ice storage tank 14. The salt concentration of the cold seawater stored in the cold seawater storage means 27 is a normal seawater salt concentration (around 3.5%). Mixed dish In the case where the crushed ice is preferred, the salt concentration adjusting device 260b can be selectively set so that the salt concentration of the salt water mixed sherbet ice can be adjusted and the temperature of the salt water mixed sherbet ice can be set to -1 ° C. The adjusted mixed water having a salt concentration of, for example, 1% (mixed water of fresh water 24 and seawater 23) is supplied into the ice making device 1 on the downstream side of the circulation pump 11 by the salt concentration adjusting pump 262. Is.

  The salinity concentration adjusting device 260b has the same configuration and the same function as the above-described salinity concentration adjusting device 260a, but the salinity concentration sensor 26 is returned to the ice making device 1 from the water storage tank 14.
