The temperature gauge 8, vacuum pressure gauge 9 or high-pressure pressure gauge 10 are used to monitor the pressure value and temperature value. Through the first baffle 36 and the second baffle 40, when the fan 11 is working, the cold air blown out by the fan 11 can be guided to the area of the storage rack 13. The cold air passes through the storage rack 13, circulates around and returns to the back of the fan 11. As the temperature inside the tank body 1 continues to drop, inflation can be continued until the set pressure value is reached, and then the solenoid valve 4 is closed. According to the frozen set time, after the time is up, open the solenoid valve 4 to relieve the pressure until it is balanced with the external atmospheric pressure, and keep the solenoid valve 4 open. After the pressure inside and outside the container is balanced, open the door body 6 to take out the food.
