Description

  There are two types of thawing of frozen foodstuffs, such as infiltration thawing in water and thawing in air atmosphere, but the present invention is in the field of air atmosphere thawing.

  It is a thawing technology such as frozen fresh fish meat, etc., and it relates to a thawing machine that thaws in a single unit of time without heating in air, without impairing the freshness and umami taste.

  In the conventional thawing method of frozen food, frozen fish meat etc. are infiltrated with warm water, thawed by leaving in the natural world, or expensive electromagnetic wave thawing due to high power consumption, etc. Excessive thawing loss occurs due to long-term thawing under assumption, and in the case of insufficient thawing amount, there is a risk of credit due to heating rapid thawing, and it is far from reproducing umami taste that frozen foods in particular have, especially for long thawing. It may also be a breeding ground for the growth of various bacteria that attach when frozen.

The factors of chewing are the temperature and humidity of the thawing atmosphere, and the conventional thawing method by prolonged thawing in hours.

Display of invention

Problems that the Invention is to Solve

  Generally speaking, conventional thawing techniques for frozen products require a long time for thawing, so the core of the frozen material remains around the crust until it thaws, and most parts including the crust undergo oxidative degradation, sometimes With the deterioration due to dryness, overheating and thawing due to boiler vapor or warm air supply, natural thawing, etc., the growth danger of attached fungi is also considered, and the original freshness and taste of holding of foodstuffs of persimmon disappears .

  The second problem is that thawing is also performed due to a temperature difference with the frozen product due to heating, such as steam introduction or warm air thawing to thaw, and the quality deterioration due to freshness deterioration causes the food to have The loss of umami has occurred.

    There are various thawing techniques for frozen products, but the essence of the thawing technique is rapid thawing at low temperature and fresh thawing, and the reproduction of the umami flavor of the persimmon food and the energy saving and inexpensive thawing technique, all of these There is no comprehensive thawing technology.

  In addition to expensive and high power consumption, electromagnetic wave thawing to human body is comparable to heat thawing by thawing by hydrogen friction of the freezing principle by vibration friction, it goes against modern energy saving era, it is far from fresh thawing.

  Although the steam blowing and thawing can prevent the drying deterioration, the heating temperature difference thawing does not distort the freshness deterioration.

  Exposure to normal temperature and thawing is accompanied by adhesion bacteria at the time of freezing, airborne miscellaneous bacteria adhesion including adhesion, pest risk increase hygiene hazards and long time lapse thawing, so that their humidity and temperature of fungal breeding conditions It should be a hotbed and should be avoided, including freshness deterioration.

  The low-temperature temperature difference thawing transferred from the freezer to the refrigerator is thawing for a very long time, and it is not suitable for general household thawing processing and is not suitable for business thawing processing.

  Commercial thawing technology requires thawing every minute from the next processing step, and at the same time, it is not complete thawing sometimes in the calculation of the estimated elapsed time to shift to the next process, and the thawing technology can judge about 80% thawing I can not find it.

Means to solve the problem

  In order to always thaw the same frozen material for a certain period of time in the professional processing process etc., it is necessary to shut off the walls, ceiling, and floor around the thawing room from the outside air in order to eliminate the influence of the outside air temperature. , It is necessary to shut off the periphery of the thawing chamber with a heat insulating material or the like.

  In the equipment room adjacent to the thawing chamber, a humidifier necessary for thawing treatment, an oxygen-free gas cylinder, an electric control panel, etc. are loaded, and through the adjacent partition wall, oxygen-free gas, low temperature humidified water for transpiration, air in the thawing chamber Electric power for convection fan, light for thawing indoor lighting, etc. is supplied to the thawing chamber.

  Since the thawing process promotes thawing sequentially from the periphery of the crust of the frozen material, nitrogen gas is used for the purpose of reducing the oxygen content of natural air contained in the thawing chamber to the extreme in order to prevent the oxidative degradation of the surface of the crust on initial thawing. Etc. is injected into the thawing chamber, and the existing air in the thawing chamber is forcedly discharged from the vent holes such as the air pressure control valve to reduce the oxygen content by about 20% to the limit, and the oxygen ratio around 20% in the thawing chamber Lower and prevent oxidative degradation and thaw.

  There are various types of oxygen-free gas, but there are various types such as inexpensive carbon dioxide gas, slightly expensive nitrogen gas, and expensive argon gas, but the condition of non-flammable gas is flammable and there is no flammable explosive gas. Like the air, there is also an air mixing property, and the thawing chamber is fixed in the thawing chamber so that there is no danger for workers to enter, but it mixes with the air instantaneously in combination with the air convection fan rotation, thawing even when the door is open There is no health hazard by mixing with the installation location vat, but in the case of worker intrusion work with a super large thawed storage room, an outside air introduction fan promotes entry prohibition by warning or voice until the proper oxygen mixing ratio is completed.

  Since the temperature in the thawing chamber decreases due to the insertion of the frozen substance and the humidity decrease due to the lowering of the temperature inevitably occurs, the thawing chamber is humidified by the low temperature humidifier.

  There are various low temperature humidifiers such as electric ultrasonic humidifier, water tank water surface transpiration, or water tank water siphon phenomenon soaking up and aeration, but as long as it is quick thawing, it uses quick electric transpiration humidification and uses electric ultrasonic humidifier Also, high temperature humidification methods such as boiler steam are excluded from the contrary to maintaining freshness.

  Except for the heat-treated frozen material, the sterilized frozen material is completely the same, and sometimes it may cause health problems due to the growth of surface-adhering bacteria during the thawing process, so the humidified water of the low temperature humidifier is sterilized water To ensure safety by forcing injection humidification into the thawing chamber.

  There are various sterilizers, but few sterilizers do not affect the quality of food and the smell and taste of food, and the sterilizer supply at each thawing process is assumed to be the knowledge worker's knowledge level difference and added Considering negative effects such as quantity and forgetting to add, it is judged that copper ion sterilized water by metal pure copper fiber infiltrated and mounted in the humidifier water tank is optimum from the viewpoint of continuous effect exertion, but it will be adopted if suitable .

  The maintenance of freshness by low temperature thawing does not require any increase in temperature decrease due to the frozen material inserted in the adiabatic shut off chamber, and the rapid thawing time in minutes does not require an artificial cooling device.

  However, in the anoxic space in the thawing chamber where the temperature is lowered due to the insertion of the frozen material, the temperature difference between the upper and lower temperature necessarily arises from the cooling specific gravity in the static state. It is identical.

  The purpose of installing the air convection fan in this thawing chamber is not only mere room temperature equalization but also forced convection of humidified long fine particle water droplets in the thawing chamber to conduct uniform convection in the thawing chamber, and at the same time By the difference of light weight etc., the rotational speed change function of the rotor blade is given, and drying deterioration is prevented, temperature shock is promoted simultaneously with sterilization of airborne shock waves by frozen oxygen gas forced convection degree and frozen material skin part. It also contributes to shortening the thawing time.

  The rotational speed conversion of the rotor is necessary, and when the small and light shirasu frozen block is thawed, the shirasu on the surface of the block is scattered depending on the degree of thawing in the case of strong convection, and the shredded radish and seaweed also imported from China. Similarly, in such a case the rotational speed of the air convection fan in the thawing chamber maintains commercial value at low speed.

  There are a variety of air convection fans, but in the thawing room installation location, in the case of mounting on one surface, the thawing time can be slightly different depending on the degree of the wind power, but there is no big difference. In the case of symmetrical installation, a uniform degree of wind speed impact contributes to the average simultaneous total thawing when the shapes of the frozen material inserted in the thawing chamber are substantially identical.

  The air convection fan air flow in the thawing tank mounts the air convection fan on the mounting frame in consideration of the position which gives a uniform shock wave to the frozen material as much as possible.

  Electric control panel, low temperature humidifier, nitrogen cylinder, etc. will be installed in the equipment room adjacent to the thawing chamber, and the oxygen-free gas supply pipe, power supply electric wire, nitrogen gas supply pipe will be installed through the wall of the adjacent thawing chamber .

  The various oscillating sound waves (25) electrically generated by the sound wave transmitter (24) according to claim 2 are diffused in the thawing chamber (2), and sound wave collision diffuse reflection diffusion on a wall, floor, ceiling, etc. Promote hydrogen bond release.

  The volume of the low frequency beeper does not affect the nearby workers in any way, as the thawing chamber is surrounded by the heat insulating material.

Effect of the invention

  It is a well-known fact that fresh fish meats have different degrees of maintaining freshness depending on the freezing processing method, but it is possible to faithfully reproduce the degree of freezing at the completion of freezing.

  It was also possible to reproduce freshness by thawing processing quickly in minutes and without heating, and faithful reproduction of freshness.

  It should be noted that the umami of the frozen material can be reproduced, and reproduction of the aroma and umami of the sushi sushi neta of the cocoon and the cocoon of the cocoons, and sweetness after thawing of the sweet prawn can not be obtained by conventional thawing. Increased.

  It is possible to start thawing amount processing start on the day of use on a daily basis by thawing every minute for a short time, and various risks such as loss due to excess and deficiency of thawing amount and labor cost are solved by batch thawing processing of the required amount on the next day from the previous day.

  The initial purchase investment value of the thawing machine is low, and health damage caused by fungi can be avoided, and a safe DC 24V air convection fan, forced humidification low temperature humidified steam, and a small amount of nitrogen gas are added to prevent oxidation deterioration, and for home use Contributed to a wide range from business use.

  In the case of fixed amount of frozen food purchased by ship food loading company or food processing company etc., it is absolutely impossible to judge the freshness and quality of the rattan by appearance shape observation of frozen food itself, and after thawing processing after lot purchase Even if a product with degraded freshness is found, there are cases in which a seller or a trader etc. presents a complaint with a quality deterioration at the time of thawing, and escapes with these risks. It was applicable also to frozen goods freshness judgment by a sample or a pick-up thawing test before purchasing.

  The frozen material (1) is loaded into the thawing rack (3) of the thawing chamber (2), but the configuration of the thawing rack (3) is stainless steel, and the pitch of the stacked thawing racks is 50 mm apart, as much as possible A large amount of frozen material (1) can be inserted, the space in the thawing chamber (2) is small, and the temperature decrease in the thawing chamber (2) due to the frozen material (1) insertion enables to maintain freshness by natural low temperature thawing.

  In order to maintain the same thawing time without being affected by the temperature change of the spring or summer or winter, or the installation location, to prevent the processing process from affecting, the wall of the thawing chamber by the thermal insulation (4) (5) The ceiling (6) and the floor (7) are separated, and the temperature in the thawing chamber (2) which is lowered by the insertion of the frozen material is maintained to maintain freshness by natural low temperature thawing.

  In the equipment room (8) provided adjacent to the thawing room (2), an oxygen-free high-pressure nitrogen gas cylinder (10) with a pressure reducing valve is loaded, and at the start of thawing a certain amount of nitrogen gas manually or automatically. Etc. are supplied into the thawing chamber (2) to prevent oxidative degradation in the thawing process and to maintain and maintain freshness.

  The oxygen-free gas (11) supply into the thawing chamber (2) does not have to be absolutely zero oxygen in the thawing chamber (2). For example, in the case of nitrogen gas, it has the same specific gravity as vat, and the oxygen-free gas is also supplied Since the reduction of about 20% of the existing air-containing oxygen in the thawing chamber (2), oxygen-free gas (11) forced injection is injected from the lower part of the wall (5), the existing in the thawing chamber (2) The air discharge is as a large-scale discharge from the ventilation hole (12) at the top of the wall (5) of the thawing chamber (2), avoiding as much as possible the large-scale dissipation of forced oxygen free gas (11) to prevent oxidative degradation during thawing. Prevent to the limit.

  In the case of a small thawing chamber (2), there is no health damage even if the thawing chamber (2) is opened at the completion of thawing, and nitrogen gas with the same specific gravity as air does not rapidly flow out, but it suddenly flows out into air temporarily Even if the oxygen content is 10% oxygen air is mixed with the existing air-containing oxygen, there is no health hazard.

  However, in the case of a large-scale thawing chamber (2) large enough to allow workers to enter the thawing chamber (2), the outside air introduction fan (13) forcibly introduces the outside air into the thawing chamber (2) It is necessary to make it uniform.

  In this case, by the sensor of the thawing chamber (2) with a door attached by an electric oxygen detector, when the door is opened, if the oxygen in the thawing chamber (2) is 10%, the voice or alarm is generated in the thawing chamber (2) Stop the invasion.

  If it is difficult to prevent the oxygen deficiency from entering the large thawing chamber (2), the nitrogen gas forced injection amount of the oxygen-free gas (11) may be reduced a little, and the thawing time is short. There is no impact on the quality of many, and it is also an idea to reduce the amount of nitrogen gas injected in terms of cost.

  In the thawing chamber (2), due to the insertion of the frozen material (1), a natural temperature drop occurs due to the same phenomenon as an ice-loading refrigerator of old times, and the air humidity due to the low temperature environment inevitably decreases. In some cases, the drying deterioration phenomenon occurs, so that the drying deterioration thawing is prevented by forcibly low temperature humidifying the thawing chamber (2) with low temperature and humidity decrease without raising the temperature.

  To do this, install a low temperature humidifier (14) such as an ultrasonic oscillation humidifier in the equipment room (8), penetrate the adjacent thawing room (2) wall (5), and thaw the low temperature transpiration humidified steam (2) Achieve low temperature freshness maintenance thawing by feeding into the inside.

  In the low temperature humidification method, there is a method to absorb the stored water in the humidifier water tank (15) with resin cloth etc. by physical siphon phenomenon used in the residential area humidifier, expand the surface area, and transpire with a fan. In unit time thawing, the humidification function may be weak, and ultrasonic forced transpiration humidification may be preferable. ,

  Another function of the low temperature humidifier (14) is that there is no frozen material in the world except various high temperature processed sterilized foodstuffs, and various surface germs have been sterilized. There is also a danger, and it is impossible to clean and clean all the equipment at every thawing frequency including various shelves in the thawing chamber (2), and it is better to always sterilize all of them. Needless to say.

  In order to do so, it is suggested that various medicines or electrical ozone generators be installed in the humidifier tank (15) of various humidification equipment, but strict maintenance of the amount of medicine addition is dangerous at the operator knowledge level and ozone It was noted that O3 forced oxidants cause health problems depending on the amount of ozone generated.

  In the case of carrying out sterilization and thawing, the natural metal copper ion sterilization method was adopted from the viewpoint of continuity and safety.

  The reason for using metallic copper as a sterilizing agent (16) is that the same amount of fresh water is injected into a copper container and an iron container, and there is a large difference in fresh water rot when left for a fixed period. Efficacy has been proved by experiments with various microbes that kill microbes by ultra-fine copper fiber by a late Eguchi, and effectiveness is proved, and also late Eguchi Otomu and the virus at the Tottori University Faculty of Agriculture attached bird-derived zoonotic epidemiological research center professor Ito Keisuke Sterilization effects have also been demonstrated, and the adoption of ultra-fine copper fibers has been decided.

  When sterilizing agent (16) starts the frozen material (1) inside the thawing chamber (2) and sterilizes the whole including the equipment installed in the thawing chamber (2), the humidifier of the low temperature humidifier (14) A 30 micron pure copper ultra-fine pure copper fiber (17) is infiltrated into the water in the water tank (15) in a fixed amount according to the amount of water storage to convert it into copper ion sterile water (18) and forced transpiration to thawing chamber (2) B) to fill the entire inside of the thawing chamber (2), and exerts a sterilizing effect on all attached bacteria of the air convection fan (19).

  However, it is also possible to exclude the use of the sterilizing agent (15) when the frozen product is an acetic acid-processed product such as frozen vinegar of fish and shellfish and there is no adhesion of various fungi.

  In the stationary air space in the thawing chamber (2) into which the frozen material (1) is inserted in the thawing process, a temperature difference between the upper and lower is generated by air cooling with the frozen material (1). Completed in an instant, the humidified transpiration supply pressure from the low temperature humidifier (14) is also weak, and the thawing chamber (2) necessarily needs the elimination of the temperature difference that can be made up and down, and it is installed in the thawing chamber (2) The wind speed is adjustable by the adjustable air convection fan (19).

  The main purpose of the air convection fan (19) in the thawing chamber (2) is to adjust the rotational speed of the rotor (20) according to the type of the frozen material (1) in the thawing chamber (2) under a low temperature ambient environment. The shock wave (21) humidified air is applied almost uniformly to the frozen material (1) to promote natural heat conduction during the thawing process of the frozen material (1), and the difference between the core temperature and the external temperature is reduced. Fresh thawing was achieved and, of course, uniform thawing with equal temperature was possible throughout the thawing chamber (2).

  In order to apply the humidified air shock wave (21) to the frozen material (1) inserted into the thawing chamber (2), for example, a frozen material (1) for thawing purpose such as a salmon opener frozen and shirasu overnight dried frozen block There is a need to change the air volume depending on the volume shape and mass etc. The change of the air volume and the wind speed is made possible by the change of the rotational speed of the rotor blade (20) of the air convection fan (19), and the thawing function is enhanced.

  The function of this air convection fan (19) is the wall (5) by the air convection fan (19) in the space in the thawing chamber (2), together with the direct humidified air shock wave (21) to the frozen material (1) Impact shock waves with the ceiling (6) and the floor (7) and air weak vibration waves (22) due to air-air collisions also contribute to low temperature rapid thawing.

  There are various types of air convection fan (19), such as square or wave-shaped axial flow fan, long-shaped sirocco fan, one-way straight-forward turbo fan, etc. The convective fan mounting frame (23) can be moved at a fixed distance from the frozen material (1) depending on the type of frozen material (1), and at the same time combined with the rotational speed conversion of the rotor (20), the best thawing process Is possible.

  The functionality given to the thawing process of the air convection fan (19) is large, and the mounting position of the air convection fan (19) in the thawing chamber (2) is important for chewing, and it is attached to the convection fan mounting frame (23) The number of the air convection fan (19) is equal in order to generate the uniform air volume in the whole area of the thawing chamber (2). In the case of mounting on (23), mount the height on the left and right with alternating steps and avoid collision in the thawing chamber (2) of the wind direction wind power on both left and right sides, as much as possible to frozen products (1) Make an average contact of the humidified air shock wave (21).

In the second aspect, various oscillation sound waves (26) by the sound wave transmitter (25) by the electric circuit are mounted in the thawing chamber (2), and the release of hydrogen bond is promoted by the air vibration in the chamber (2). Was also effective.

  Sometimes it is necessary to select the kind of music, but the air vibration by music is comparable to various oscillation sound waves (26).

  As described above, it is a thawing machine that performs drying prevention with low temperature humidification, prevents oxidative degradation in anoxic state without heating with each device, and reproduces thawing umami taste by minute freshness reproduction in a natural environment. .

  The third aspect is food processing processing such as thawing or freezing, and in the case where visual confirmation is not possible and there is no method other than job type confirmation, confirmation with the conventional delivery door opening etc. is in the thawing room There is a large change in the environment and sometimes there is a risk of quality change, and it is necessary to prevent these problems and pursue fresh thawing.

  For the purpose of eyebrows, attach an open / close window (27) with an easy-to-see area such as the wall (5) of the thawing chamber (2) or the door for loading etc. It is also possible to provide an anti-fogging function with heavy glass or the like.

  In particular, with the introduction of the oxygen-free gas (11) of the present invention, it is also possible to have an important climate in maintaining the oxidation deterioration prevention mechanism as much as possible.
