Principle
The principle of a vacuum precooler is to reduce the solubility of gases in a vacuum state, resulting in a decrease in oxygen and other gases in the air, thereby lowering the ambient temperature. During the pre cooling process, the chives are placed in a vacuum chamber and the air in the environment is extracted by vacuuming, reducing the oxygen and other gases in the environment, thereby lowering the ambient temperature and achieving the purpose of pre cooling. At the same time, due to the decrease in gas solubility under vacuum, the water in chives will evaporate in the form of steam, thereby achieving dehydration and helping to extend the shelf life of chives.
