Description

Technical Field

[0001] This utility model relates to the field of food preservation technology, and in particular to a vacuum precooling machine for food preservation. Background Technology

[0002] Vacuum precooling preservation is a physical preservation technology that relies on reducing the air pressure inside the chamber to change the boiling point of water, causing the surface water and internal free ion water of fruits and vegetables to evaporate and boil at low temperatures, thereby carrying away heat to achieve the purpose of cooling.
