- the length is less than or equal to the first time length threshold.
- the first time length threshold ranges from 5 to 10 minutes.
- the lowest temperature point referred to herein refers to the lowest temperature before the temperature of the meat food is raised during the freezing process. Because the meat food suddenly appears at a slightly higher temperature during the freezing process and then continues to fall, then the temperature point before the point where this temperature is slightly higher is the lowest point described here, which can also be understood as a pole.

- the subsequent temperature recovery process is performed immediately to ensure that the meat does not freeze.
- the plurality of temperature sensors can always compare the temperature. If more than two temperature sensors detect temperatures below a certain value (for example, -10 ° C), it means that there is a large amount of freezing in the room.

- the t 0 level after which the damper is half-opened to control the reduction of the cooling capacity, causes the food to slowly enter the supercooling or freezing process, thereby effectively prolonging the storage time at low temperatures.
- the step 105 specifically includes:
- Step 105a control chamber between said heating operation in accordance with the third target temperature T 3, the third target temperature T 3 in the range of -1 ⁇ 6 °C.
