The present invention relates to a method for freezing and thawing foods, and an apparatus for freezing and thawing foods, which can be processed flexibly according to the type, physical properties, or shape of the foods, and which does not impair the inherent quality of the foods.

固定して行っている。[Prior art] Conventionally, when processing processed foods such as bonito, tuna, meat and ham, and other foods, when freezing or thawing a plurality of products having different types, physical properties, or shapes, it is necessary to freeze or thaw them. Flexibly changing the freezing or thawing conditions in terms of physical properties, shapes, etc. will make the freezing and thawing operations complicated, and will also make food-specific frozen preservation and thawing recovery difficult. Regardless, processing conditions are fixed exclusively during freezing or thawing.

しく商品価値を損なう欠点がある。[Problems to be Solved by the Invention] Processed foods such as bonito, tuna, meat, ham, and other foods are subject to the generation of internal pressure due to freeze expansion of the moisture content during freezing or thawing, and the dissipation of internal pressure due to a decrease in the freezing rate. However, if the food is rapidly frozen or thawed under fixed conditions regardless of its physical properties, shape, etc., the internal pressure will rise abnormally, causing cracks in the food. Otherwise, breakage or deformation such as ridges may occur, and frozen or thawed products may undergo freezing denaturation consisting of changes in tissue structure and colloid structure, which has the disadvantage of significantly reducing commercial value.

The purpose of the present invention is to provide a method for freezing and thawing foods, which does not affect the inherent quality of foods, and an apparatus therefor.

A media spraying header is placed for each processed food such as tuna neck or meat and ham, and a cooling or heating medium is sprayed from the spray head to achieve optimal freezing or freezing depending on the physical properties, shape, etc. of the food. Since the thawing processing conditions are selected by the freezing or thawing processing program, it is possible to perform the optimal processing flexibly according to the physical properties, shape, etc. of each frozen or thawed product. By interrupting the freezing or thawing process for a certain period of time (soaking process) before damage occurs due to generation of nuclear crystals, the expansion pressure accumulated inside the nuclei is dissipated to the outside, and then the freezing or thawing process is continued. By doing so, even if the internal pressure increases afterwards, it is possible to prevent damage to the nucleus crystals due to increased or reduced formation of the frozen layer, and by applying optimal processing, changes in the tissue structure of the frozen or thawed product can be prevented. No change occurs, and there is no risk of freezing denaturation.

置１０で制御し、複数回反覆する。Next, when using the present invention to freeze or thaw a plurality of foods having different physical properties, shapes, etc., the automatic valve 9 is opened during the freezing or thawing process, and the four-way switching valve is opened during the freezing process. 15 and 15' to the freezing direction, and communicate the freezing sides 15a and 15a' with the common sides 15b and 15b', the medium 1 in the medium storage tank 5 at the bottom of the freeze/thaw chamber a is connected to the discharge port. From the piping 5a to the medium circulation pump 14
The refrigerant flows into the evaporator 8 through the pipe 16 that passes through the evaporator 8 via the four-way switching valve 15', and the evaporator 8 sucks in the low-pressure refrigerant liquid from the expansion valve 7 and vaporizes it. The medium 1 is cooled by removing heat of vaporization from the medium 1 passing through the medium 16, and is cooled through the four-way switching valve 15 and automatic valve 9 to the upper and lower left and right parts of the frozen or thawed product C, or the ceiling of the freezing and thawing warehouse a. Nucleic crystals C are sprayed onto frozen or thawed products C from individual media scattering headers 6.6 placed on the front, back, left and right sides of the floor.
It cools and freezes when it comes into contact with. In addition, in the case of the thawing process, when the four-way switching valves 15 and 15' are switched to the thawing direction and the thawing sides 15c and 15c' are communicated with the common sides 15b and 15b', the medium in the medium storage tank 5 is controlled by the medium circulation pump 14. 1 flows into the condenser 12 through a pipe 16' that passes through the condensing agricultural equipment 2, and in the condenser 12, the compressor 11
Heat exchange takes place between the high-temperature, high-pressure refrigerant gas from the pipe 16' and the medium 1 passing through the pipe 16', and the refrigerant gas changes into a high-pressure refrigerant liquid, and the medium 1 loses heat of condensation from the refrigerant gas to the refrigerant liquid. The material is heated to a high temperature and is sprayed onto the frozen or thawed product C through the four-way switching valve 15 and the automatic valve 9 from each of the medium dispersion headers 6゜6, where it comes into contact with the nuclear crystals C, heats them, and thaws them. It is. Furthermore, during the temperature soaking process, the automatic valve 9 is closed and the cooling or heating medium 1 is not supplied into the freezing/thawing chamber a, and the temperature is soaked in the air. The soaking process is controlled individually by each individual control device 10 for each frozen or thawed product C based on a freezing or thawing processing program prepared in advance according to the type, physical properties, and shape of the food, and is repeated multiple times.

能となる。In addition, in the case of the freezing and thawing warehouse a shown in FIG. 1, since the frozen or thawed products C do not move during the freezing or thawing process, each medium distribution header 6 individually corresponds to the frozen or thawed products C.
．． Freezing or thawing processing of a plurality of foods having different physical properties, shapes, etc. can be performed by incorporating each individual control device 10 for controlling the dispersion of the medium 1 from 6 into the fixed collective operation panel d shown in FIG. 3A. In the case of freezing and thawing warehouse a shown in Fig. 2, since the frozen or thawed product C moves during the freezing or thawing process, the frozen or thawed product C can be controlled simultaneously and individually. By incorporating individual control devices 10 corresponding to each frozen or thawed product C into a rotary collection operation panel e that operates in conjunction with the passing or stopping position of the It becomes possible to simultaneously and individually control the freezing or thawing processes in the process.
