The dissertation presents somecontents about the vacuum precooling as follows: 1. Studies on the evaporation cooling principles of fruit and vegetable There are different optimal storing conditions for different vegetables and fruits.And the vegetable and fruit precooled by vacuum must be fit with the storingcondition. A low temperature will result in the frozen scald, and a high temperaturewill not meet the precooling objective.
