When taking an item after partitioning the area, only the cold air in that area is lost, avoiding affecting the rest of the device, saving energy and reducing costs. After placing the object inside the device, start the semiconductor refrigeration block 14 inside the cold box 4 to cool the gas inside the cold box 4. Then, cooperate with the recovery pipe 17 and the air pump 18 to transport the cold air into the cooling pipe 16 to cool and freeze the inside of the device. The heated gas then returns to the cold box 4 along the water inlet pipe 15 for re-cooling. During the cooling process, the motor 8 can be used to drive the threaded rod 9 to rotate forward and backward periodically, so that the slider 10 moves up and down inside the box body 1, and cooperate with the fan 11 to improve the cold air circulation rate inside the box body 1 and improve the freezing efficiency of the object.
