After processing the vegetables, the vacuum cooler needs to inhale the outside air into the vacuum box, and the door can only be opened after the air pressure inside and outside is balanced.
The air inhaled by our vacuum cooler will enter the vacuum chamber after cooling down, so that the cooled vegetables will not be returned to room temperature.
In addition, we added a muffler, the noise is very loud when opening the door, and the noise is minimized through the muffler.
