Description

  Mainly in the field of thawing processing of frozen ingredients, frozen ingredients such as single fresh fish and meat chunks, frozen ingredients such as fine shirauo and fine chirijaja block frozen, or ingredients that cannot be defrosted underwater except in vacuum packaging such as Japanese confectionery Is a comprehensive field of thawing in the air, incidental chilling and freezing.

  As an application, it is also used for medical ecological preservation, for example, oxygen-free low-temperature rapid thawing in organ transplant frozen storage, or cryopreservation of transfused blood, oxygen-free low-temperature rapid thawing, and medical research.

  As an application, it is also used for electrical resistance verification and humidity and temperature studies.

  As an application, it is also used for verification of various changes by temperature and humidity during material development.

  In the thawing of frozen foods, there are thawing in the air, thawing in water and thawing in electric water, or defrosting in tap water, and in some cases, thawing by standing in the air at natural temperature.

  In the case of thawing in water, throwing the material to be thawed into the water storage tank and thawing it is impossible to thaw due to a drop in water temperature. .

  In both the water and the air, there are thawing techniques for the low-frequency or high-frequency single-width amplitude oscillation inherent in the constant amplitude frequency band in the oscillation elements by the existing electric oscillation device. The inferior processing power of the shaded part and the back part other than the direct part of the object to be processed is fatal wound, consumes a lot of power against the low-carbon society, and the equipment is very expensive. There are various problems in health management.

  When thawing frozen foods in water or in the air, the molecular vibrations of the material to be defrosted by various artificial single-wave electric high-frequency oscillators are mainly due to molecular frictional heat thawing, although there are some differences. Along with consumption, both low-frequency and high-frequency oscillators have different lifetimes in the frequency band, but they require annual replacement due to reduced functionality, and sometimes the noise adversely affects nearby precision electrical equipment depending on the frequency band. Also occurs.

  In the air thawing of frozen ingredients, it takes a long time from the previous day, and if it is put in a low temperature atmosphere, it requires low temperature drying and further thawing for a long time. In the previous thawing of the estimated amount required for the next day, an excess or deficiency of about 30% on the day occurs on average, and if the remainder is lost, tangible and intangible losses such as a microwave oven thawing that is unrelated to freshness will occur. It has become a common sense theory of everyday life.

  In particular, it must be pointed out that, in recent years, even in products that have been demonstrating the maintenance of freshness with the -7 ° C freezing technology called supercooling instant freezing, all small objects are overcooled, Although it does not work for -30 ° C to -60 ° C refrigeration processing of thick shrimp blocks or meat chunks etc., it is good, no matter how highly frozen products are frozen, There is no meaning at all, and the major problem of the thawing technology is that the thawing atmosphere temperature is lowered to maintain the freshness even a little, but from the preconceived common sense theory that there is only a long time thawing due to the temperature difference, unavoidable freshness defrosting Therefore, frozen and thawed products have become synonymous with low images from the general public.

  In particular, frozen refrigerators that are flooded in the city are frozen thawing rooms with quick thawing rooms and moisturizing refrigerated rooms not in the whole world, but frozen foods for home use, especially for Western home parties. It is common knowledge that thawing is simply transferred from the freezer to the refrigerator and dried for a long time.

  Originally, frozen ingredients for the purpose of maintaining freshness, when necessary, immediately maintain the freshness, quickly thaw, quickly thaw, order comes at the restaurant and thaw cooks, housewives are on the verge of menu cooking such as dinner If it cannot be thawed, there is no meaning of freshness-maintaining frozen food, and unfortunately there are no corresponding products worldwide.

  Many of the conventional thawing of commercial frozen foods are performed by filling small and large tanks with fresh water, immersing the object to be processed, and adding a large amount of material to be thawed to reduce the water temperature. Or avoiding a temperature drop due to the tap water discharged, but still a huge amount of waste is spent on freshness deterioration and water charges and wastewater treatment by thawing for a long time, and even in the refrigeration temperature in the air is expensive with an artificial electric oscillation device With ultrasonic waves in a certain frequency band with high power consumption, more or less, molecular vibration frictional heat generation and thawing are all over.

  In addition, animal organs for medical research or cryopreservation and electrical resistance tests can be easily installed in an ultra-low temperature atmosphere. Even in the vast United States, organs are transported by cold storage at room temperature.

Japanese Patent Application No. 2009-20783 Japanese Patent Application No. 2009-118018 Japanese Patent Application No. 2009-119237 Japanese Patent Application No. 2009-141652 Japanese Patent Application No. 2009-181044

  First and foremost, all the modern processing machines must be energy-saving equipment that matches the low-carbon society that is the condition of humankind on earth.

  In order to faithfully reproduce the freshness at the completion of freezing processing, such as thawing processing of a wide variety of frozen foods, etc., at the lowest possible temperature, sterilizing and thawing the attached fungi as necessary. All of these must be maintained functionally without the use of dangerous artificial ultrasonic oscillators, without absolute safety and at low cost.

  In the current thawing, there is an estimated error of around 30% in the expected amount of thawing process for long time thawing from the previous day for both underwater thawing processing or in-air thawing processing, the thawing amount is excessive or insufficient, etc. Tangible and intangible loss is a major issue in daily life, even when working overtime due to long hours.

  In the air thawing method, frozen processed products are left in the atmosphere at that temperature, and there are even products that have been thawed for a long period of time. Also, the breeding of miscellaneous bacteria is a major issue.

  In the air thawing method, it is transferred from a freezer, which is a well-known fact, to around 5 ° C in a refrigerator, and when it is a food that deteriorates the freshness of the low-temperature drying for a long time and greatly reduces the weight, for example, a chimney coco freezing block, It is frozen in a block shape of around 6kg with various bacteria adhering to it, and by thawing in the air for a long time, the outer periphery of the block grows in the presence of various bacteria until the core of the block is thawed. .

  In the air thawing method, if the device is transferred to room temperature or refrigerated temperature and is also used with an electrical ultrasonic oscillator, it consumes a large amount of power necessary for the thawing process and, depending on the frequency, affects the human body and affects Notification is also necessary and health safety should be considered.

  In addition, the forced vibration wavelength from the vibration element by the conventional electric ultrasonic oscillator has a straight traveling property, and the higher the frequency, the greater the molecular vibration frictional heat of the object to be processed. This should lead to tissue degradation of the wave receiving surface, and structural safety should be prohibited in the case of in-air ultrasonic oscillation, while underwater oscillation should be prohibited from the operator's underwater contact, although it may affect health. There are no legal restrictions, but workers' health protection should be handled carefully.

  In addition, Irico's original salmon fry, which is indispensable for Japanese cuisine, is caught in the Seto Inland Sea of Japan, but it can be stored frozen during large fishing and thawed when necessary. There are countless ingredients that cannot be processed, and there is currently only low-temperature dry thawing.

  In Japan, due to legal restrictions, the current situation is not so necessary apart from the future, but in many countries, including Europe and the United States, the fine cells of egg spermatozoa are obtained by ecological transplantation medicine or by thawing treatment for cryopreservation for the purpose of living transplantation. Even so, the degree of self-re-inhalation of nuclear water that has been released at low temperatures is another way to determine whether or not it can be used. There is a demand for a rapid thawing strategy without drying in an oxygen-free, low-temperature atmosphere.

  In addition, the use of the large central weathering test equipment is not bad for electrical resistance verification and humidity and temperature studies, but it has been conveniently reduced in size for various purposes in independent laboratories in each distributed research building. Equipment is desired.

  The same applies to verification of various changes due to the relationship between temperature, humidity, and oxygen during material development.

  Importantly, consumers should point out the technical or spiritual challenges of the refrigeration industry where the thawing method, which is the fate of frozen foods, escapes the risks of thawing degradation. The processing industry and consumers are all immersed in the current preconceptions of temperature difference refrigeration and temperature difference thawing, and no energy and safe freshness preservation and thawing are not surprising.

Means to solve the problem

  The basic conditions for reproduction of freshness required for thawing treatment in the food, medical, or various research fields are oxygen free, low temperature, dry, rapid, simple operation, safety, running, both in water and in air. Low costs, low equipment costs, and a low-carbon society at the same time are all essential conditions.

  In order to make all the items of each of these conditions possible, it should be noted that it is best to discard the common-sense view and use liquefied nitrogen gas, etc. that is used only for refrigeration, such as liquefied nitrogen gas at an extremely low temperature of -196 ° C. It is.

  The refrigeration processing technology in various fields using low-temperature oxygen-free liquefied gas such as low-temperature liquefied nitrogen gas or low-temperature liquefied carbon dioxide gas is a well-known fact from the past.

  In the process that already frozen processed products cannot be avoided, if the thawing treatment technology can be implemented with this oxygen-free liquefied gas, the frozen food industry will be transformed, and for the first time in the world, oxygen-free, heatless, dry, low temperature Maintenance, rapid minute-by-minute, no drip, fresh blood, and on top of that, chilled processing, low-temperature sterilization, and freezing are also supported.

  The fundamental difference between the present invention and various commercially available thawing machines is that a set of expensive fixed-frequency electric ultrasonic oscillators and a cooling device using a refrigerant, and a thawing that spends a long time leading to loss of running water, especially deterioration of freshness. The neck point of will be eliminated.

  In addition to the extremely simple configuration, the consumption of the oxygen-free gas liquid (2) and oxygen-free gas (3) and the power consumption of the auxiliary equipment are extremely small. That is, it has the same structure up to a small portable thawing model, and there are many advantages of the present invention such as non-heating, low temperature, rapid, freshness-maintaining thawing treatment with 196 ° C. liquefied nitrogen gas, etc. The problem of excess and deficiency due to long-term pre-thawing, such as transferring and thawing from a typical freezer to a refrigerator, is also resolved naturally, and two types of chilled processing at room temperature or low temperature, a rapid water thawing machine and a rapid air thawing machine, are also incidentally chilled. And make it possible to freeze processing.

  For example, refrigeration using liquefied nitrogen gas at −196 ° C. is a well-known fact since ancient times, and refrigeration at ultra-low temperatures is refrigeration based on a simple temperature difference, and even elementary school students are in the common sense.

  However, when it comes to thawing treatment using liquefied nitrogen gas at -196 ° C, even the manufacturing engineers in the liquefied nitrogen refrigeration industry around the world, both domestically and overseas, have a common sense prejudice of refrigeration due to temperature differences and thawing due to temperature differences Therefore, the present invention and the conventional recognition concept are technologies that are far from the sky, but as long as refrigeration and thawing have the same purpose of maintaining freshness, -196 ° C liquefied nitrogen gas is a similar category of refrigeration and thawing. It must be noted that it is a medium material.

  No, more than that, -1956 ° C. liquefied nitrogen gas is a medium material more suitable for thawing treatment than refrigeration processing medium.

  This is because refrigeration in an ultra-low temperature and oxygen-free environment seems to be suitable for maintaining freshness, but the relative humidity is zero in the low temperature range where refrigeration is possible, and even if humidified in the temporary ultra low temperature range, It is a well-known fact that the water freezes instantaneously with independent fine water droplets, and there is no meaning in preventing moisture evaporation of the frozen processed product. One example is an adapted egg specimen for storage of in vitro fertilized eggs at -196 ° C liquefied nitrogen In some cases, the egg itself in the chalet can be used to absorb special water, and only the water-absorbed egg enters the fertilization process, and not all eggs stored at ultra-low temperatures are suitable for fertilization. For this reason, even quick freezing with ultra-low temperature liquid nitrogen has drawbacks.

  However, the thawing conditions are different from the freezing temperature, although the temperature is low, the thawing atmosphere temperature is often around 5 ° C. to less than 10 ° C. in both air thawing and air thawing. Even in the case of medium thawing, in this temperature range, the humidity can be easily increased by a humidifier, and in the thawing process, it is possible to even supplement the moisture in the body that has been evaporated during low-temperature freezing.

  In both the underwater thawing process and the air thawing process, the primary purpose is to prevent oxidative deterioration in order to maintain freshness. Although it is covered with oxidized drip foam, no drip foam is generated at all in the aeration of low-temperature liquefied oxygen-free gas, and it can be quickly thawed by underwater explosion ultrasonic wave oscillation of complex frequency due to temperature difference with treated water. Also, in the air thawing, if 20% air in the treatment tank is exchanged by oxygen-free gas injection to make an oxygen-free gas space, it is humidified oxygen-free gas and the oxygen-free gas in the treatment tank is compressed by a pressurized airflow fan. Wind-velocity impact shock waves generated by suction blowing in circulation can be quickly thawed with natural low-frequency ultrasonic waves.

  Naturally, thawing treatment in water and thawing treatment in air is a low-temperature atmosphere for the purpose of maintaining freshness, and it is possible to lower the temperature sufficiently even if the liquefied nitrogen gas is continuously filled up to a certain temperature drop in the treatment tank. There is no need for a treated water cooling device or an air cooling device that consumes a large amount of trouble and has a high occurrence of failure.

  In the air thawing process, it is important to thaw in a dry environment, and the external moisture transpiration of the material to be thawed inevitably leaks the internal moisture to the outside due to osmotic pressure, resulting in loss of freshness and weight loss. However, in order to avoid this moisture transpiration deterioration, the oxygen-free gas in the tank is sucked with a humidifier and returned to the treatment tank cyclically with the humidified oxygen-free gas, and the freshness is constantly maintained while maintaining the specified humidity in the process tank. .

  In portable thawing models, if crushed ice is loaded naked instead of a humidifier, the crushed ice is thawed by a pressurized airflow fan and moisture is evaporated to cool the transpiration heat and simultaneously humidify the treatment tank. Is also connected.

  The only thing that can be done with all of these ideal environments is to dissipate the low-temperature, oxygen-free, humidified gas from the pressurized airflow fan into the thawing material. Low-frequency ultrasonic waves were also generated by the diffusion collision of oxygen-free gas, leading to an increase in the thawing speed comparable to underwater waves.

  This rapid thawing in the air is performed by sucking the oxygen-free humidified low-temperature gas in the treatment tank with a pressurized airflow fan and pressurizing and blowing it to the treatment object, so that the humidified water molecules in the treatment tank are turned on and off the treatment object. All combined waves are given to the frozen material by shock waves when the reflected wind collides with the whole, and it is left standing in the tank for a long time. It was proved that the equipment investment in millions of yen was reduced by eliminating the direct irradiation part of the receiving surface of the ultrasonic irradiation and the defrosting delay gap on the opposite side.

  Sterilized and thawed. Or, the purpose of sterilization washing is that the sterilization of raw frozen foods is the original form because things that should be sterilized and frozen at the time of freezing are uncertain in the importing country, or even in Japan It is opaque and is an indispensable process for thawing.

  For this purpose, various safe sterilizing agents based on the Food Safety Law are automatically or manually infused into the humidifier transpiration water in the case of thawing in the air, and in the case of thawing in water, fresh water in the treatment tank or seawater thawing water. If it is added to, the sterilization function will be exerted all over the outside of the material to be thawed to ensure safety.

  As for the safety of operation, of course, the person in charge of the kitchen who has no knowledge of software or hardware pursues safety without any danger in any situation, especially the cardiac pacemaker holding company For the sake of consideration, the use of radio waves, magnetic forces, infrared rays, etc., which are harmful to the human body, should not be used even if safety devices are attached.

  Reduction of running costs is a duty of equipment development companies in a low-carbon society, and the amount of liquefied nitrogen gas consumption varies slightly depending on the type of material to be thawed. The liquefied nitrogen consumption per kg is 0.1 kg to 0.2 kg, and 3% to 5% of the amount consumed for the freezing process is sufficient.

  The equipment costs are high thawing function, but electrical equipment other than pipes is not necessary except for treated water circulating water pump for underwater thawing treatment, pressurized airflow fan and humidifier for air thawing treatment. Such a cooling device, and an apparatus of millions of yen such as an ultrasonic oscillation device and an ultrasonic vibration element are unnecessary, and both the equipment cost and the power consumption are small.

  "Claim 2" is a small portable product in which a small model of the present invention is inserted and installed in a well-known commercial refrigerator-freezer by a rail roller method, etc., and humidity is added to the cooling air by the refrigeration temperature by a humidifier. It is equipped with a low-temperature humidified oxygen-free water or air thawing machine with an oxygen-free gas cylinder (16), and it can maintain the freshness maintaining thawing difference of cloud mud from long-term low-temperature drying deterioration thawing in conventional refrigerator transfer. It is a freezing and thawing refrigerator with a thawing chamber.

The invention's effect

  Ultra-low temperature liquefied gas, for example -196 ° C liquefied nitrogen gas, is extremely low temperature except for refrigeration, so it seems that it was unexpected to use it for thawing process.

BEST MODE FOR CARRYING OUT THE INVENTION

  Claim 1 describes an underwater defroster and an air defroster using a low-temperature liquefied gas. First, an underwater defroster shell will be described.

  In the case of the underwater thawing machine shown in FIG. 1 etc., the treated water (6) of fresh water or salt water is placed in the treatment tank (5) of the thawing machine body (4) and the space above the surface of the treatment tank (5). Hold and fill.

  In order to rapidly lower the temperature of the treated water (6) in advance, the oxygen-free gas liquid (2) may be introduced from the low-temperature oxygen-free liquefied gas storage tank (1) into the treatment tank (5). It is better to reduce the temperature of the treated water (6) by introducing the oxygen-free gas liquid (2) only when the temperature of the treated water (6) drops several degrees Celsius at the same time as the workpiece (7) is charged. -.

  The filling amount of the treated water (6) is such that the space above the water surface in the treatment tank (5) is filled with the oxygen-free gas (3) even when the object to be treated (7) is charged, and the suction and discharge circulation described later is used. Possess the required volume of space.

The oxygen-free gas liquid (2) or oxygen-free gas (3) from the low-temperature oxygen-free liquefied gas storage tank (1) is passed through the oxygen-free liquefied gas flow rate adjustment valve (8) in the treatment tank (5). In the treated water (6), the gas diffusion box or pipe (9) installed directly in the treated water (6) or directly connected to the microbubble generator (10) is attached to the treated water (6). Oxygen gas underwater bubbles (11) are generated.
The anaerobic gas underwater bubbles (11) are injected into the treated water (6) under the pressure of the circulated water circulating pump (13) toward the workpiece (7) in the reed (12). However, the reason for this is to avoid an unnecessary loss of the oxygen-free gas (3) if it is always operated at the discharge pressure of the low-temperature oxygen-free liquefied gas storage tank (1) itself.

  The oxygen-free gas (3) remaining in the space above the surface of the treated water (6) is sucked by the upper space gas suction pipe (15) in the tank attached to the discharge pipe (14) of the treated water circulation water flow pump (13). The oxygen-free gas (3) floating on the water surface is again sucked by the tank upper space gas suction pipe (15), and this is repeated.

  However, in a small model including a portable processing machine, an oxygen-free gas (3) is introduced into the space above the surface of the treated water (6) in the processing tank (5) by a small portable oxygen-free gas cylinder (16). It is also possible to expel aerobic air by spraying into the anaerobic gas space (17).

  When the oxygen-free gas (3) is circulated and used in the treatment tank (5), fine water bubbles can be generated even at the discharge pressure of the treated water circulation water flow pump (13), but if necessary, a fine bubble generator (10) can be used. Supply via mounting.

  The diameter of one or more diffusion opening holes (18) opened in the gas diffusion box or tube (9) may be increased from 1 mm to 2 mm in the case of high pressure injection and about 5 mm in the case of low pressure. .

  In particular, the gas diffusion box or pipe (9) may be mounted vertically on the inner wall (22) of the processing tank or mounted on the processing tank lid (21) and has a certain discharge pressure.

  The model mechanism of the treated water circulating water pump (13) is a model that does not use lubricating oil in the case of the treated water (6) submersible pump. Even in the case of high voltage, the pump model is independent of the impeller chamber and the drive unit, and even if the seal is broken, the pump type is free from any leakage of lubricating oils and fats in the treated water (6).

  A perforated partition wall (19) that can be fixed or detachable, and a filtration network (20) having a fixed area that can be detached and attached by insertion, pulling up, etc. with a slight gap.

  Normally, the mesh is easy to pass through the water in the treatment tank (5), but the fine fish chimney cocoons and the reed-fishing bait amii shrimp and the like use the fine mesh net cage (12).

  The treatment tank lid (21) is capable of preventing water droplets from being scattered in the water flow in the treatment tank (5) and at the same time preventing contact mixing of anoxic gas (3) and aerobic air on the surface of the water where the air current is intense. It may be necessary to install a treatment tank lid (21).

  The material of the inner wall of the treatment tank (22) is preferably made of stainless steel having an echo and cavitation resonating function that occurs when the oxygen-free gas bubble (11) bursts. There is no problem.

  The low temperature oxygen-free gas liquid (2) and oxygen-free gas (3) use -196 ° C ultra-low temperature liquefied nitrogen gas, ultra-low temperature liquefied carbon dioxide gas, other liquefied gas, etc. It is possible to use other oxygen-free gases as long as there is no such difference between food hygiene and price.

  The treated water (6) uses fresh water or salt water when used as a thawing machine, but in the case of freezing or low temperature chilled processing used at 0 ° C. or lower, it can be treated with antifreeze water by adding ethyl alcohol or the like. To do.

If liquefied nitrogen gas, etc. is diffused in a water temperature of 4 ° C. to 10 ° C. or less than 30 ° C., a bubble temperature of around 200 ° C. will result in infinitely large and small water bubbles. Generation, bursting, underwater ultrasonic wave with geometrical amplitude, and synergistic effect with liquefied gas microbubble generator (10), transparent water instantly becomes cloudy with oxygen-free gas, High or low due to bursting of bubbles in thawing water, despite the fact that the treated water (6) is rapidly cooled and cooled to around 7 ° C due to the introduction of frozen material or the injection of ultra-low temperature oxygen-free gas liquid (2). It is assumed that the sonic energy and the cavitation energy action are based on it, but by releasing the hydrogen bond freezing, the frozen fish saury and the 20 mm thick beef-stuck frozen beef are thawed in about 1 minute. -From table household to small store, large-scale mass Until sense, simple cheap same mechanism, the underwater thawing machine according to low-temperature liquefied gas.

  Next, in the case of the air thawing machine shown in FIG. 2, there is no substitute for the treated water (6) of fresh water or salt water or antifreeze water in the treatment tank (5) of the thawing machine body (4). Let it be an oxygen gas space (17).

  When the object to be treated (7), which is already frozen, etc., is thawed, an ultra-low temperature oxygen-free gas liquid (2) may be introduced and used to rapidly lower the temperature in the treatment tank (5) in advance. However, introducing the low-temperature oxygen-free gas (3) at the same time when the object to be processed (7) is introduced to lower the temperature in the treatment tank (5) reduces the gas consumption and leads to energy saving.

  The low-temperature oxygen-free liquefied gas storage tank (1) itself already has a liquefied gas liquid discharge valve and a transpiration gas discharge valve, but it is difficult to make fine adjustments for the purpose of installation. By selecting both in the gas storage tank (1), an oxygen-free liquefied gas flow rate adjustment valve (8) that controls the discharge amount of the oxygen-free gas liquid (2) or oxygen-free gas (3) in the defroster body is installed. Then, it diffuses directly into the gas diffusion box or pipe (9) installed in the treatment tank (5) or directly into the treatment tank (5).

  In order to lower the temperature in the processing tank (5), it is possible to discharge the oxygen-free gas liquid (2) into the processing tank (5) with the discharge pressure of the low-temperature oxygen-free liquefied gas storage tank (1) itself. The oxygen-free gas (3) is continuously introduced into the treatment tank (5), and is introduced into the treatment tank (5) in a certain amount only as an excess gas is diffused out of the treatment tank (5). After that, it stops and sucks the full oxygen-free gas (3) into the treatment tank (5) by the pressurized air flow fan (23) installed in place of the treated water circulation water flow pump (13) of the underwater defroster. Discharging inside and repeating this eliminates the waste of the oxygen-free gas (3) in the low-temperature oxygen-free liquefied gas storage tank (1) with the minimum necessary consumption.

  However, in a small model including a portable processing machine, anaerobic gas (3) is sprayed into the inner space of the processing tank (5) by a small portable oxygen-free gas cylinder (16), and oxygenated air is discharged. By expelling and making an oxygen-free gas space (17), the same purpose as that of the large size is achieved.

  Even if oxygen-free gas (3) is continuously supplied in a large amount into the treatment tank (5), oxygen-free air after replacing oxygenated air in the treatment tank (5) to become an oxygen-free gas space (17) For the gas (3) supply, it is best to circulate and use the oxygen-free gas (3) in the tank for instantaneous atmospheric dissipation, but even if a large amount of oxygen-free gas (3) may be consumed, Direct use of the ultra-dry oxygen-free gas (3) is not valid, and the deicing by the pressurized air flow fan (23) of the ice block (26) put into the processing tank (5) together with the workpiece (7) is always performed. A pressurized air flow fan (23) is required as a humidification space by the humidifier (24) by transpiration humidity or oxygen-free gas (3) suction and discharge in the treatment tank (5).

  In the case where the oxygen-free gas (3) supplied by the circulation in the tank from the pressurized airflow fan (23) is above a certain pressure, the function is exhibited even if it is directly introduced into the gas diffusion box or pipe (9). When the aperture of the diffusion opening hole (18), which is attached to the gas diffusion box or pipe (9), is small, it requires a certain pressure, but the purpose is to increase the diameter of the diffusion opening hole (18). Fulfill.

  However, the humidified oxygen-free gas (3) in the treatment tank (5) is not directly passed through the gas diffusion box or the pipe (9) but directly by the pressurized air flow fan (23). A freshness-maintaining, non-drying and rapid thawing process that was not possible with low-temperature gas static thawing at a low temperature was realized.

  There are various types of mechanisms of the pressurized airflow fan (26) attached to the air defroster. However, when a gas discharge box or pipe (9) is used, a blowing pressure higher than a certain level is required. There is a pressurized airflow fan (23) or various gas pressurizers, but when blowing directly into the treatment tank (5), a turbofan, a sirocco fan, etc. are solid in consideration of static pressure. An axial fan can be used depending on the air volume.

  To install the pressurized airflow fan (23), a through hole having a discharge port diameter of one or more pressurized airflow fans (23) is separately opened in the perforated partition wall (19) having a processing tank (5) and a conduction hole. Of course, the removable filter screen (20) used for the underwater defroster is naturally removed.

  The perforated partition wall (19) can also be used as a perforated partition wall (19) with a pressurized airflow fan (23) installed for an air defroster if it can be inserted, lifted and removed in the same manner as the filtration net (20). It is desirable to replace it according to the situation and store it separately.

  The pressurized air flow fan (23) in the treatment tank (5) is turbulent, and when it is in contact with air, the specific gravity is almost the same as that of air, so the oxygen-free gas (3) is scattered outside the treatment tank.
