The vacuum system evacuates the air contained in the entire vacuum chamber. This evacuation, causing the drop in pressure inside the chamber, is what provides the opportunity for the product inside the chamber to drop in temperature by means of “evaporative cooling”. “Evaporative cooling” is achieved as the moisture in the product “boils off” under the reduced pressure inside the vacuum chamber. The air to be evacuated from the vacuum chamber not only includes the air surrounding the palletized product but also the air that is in empty spaces found inside the boxes or cartons of the product to be cooled.
