【Abstract】 The freeze-drying process of apple was researched, and the characters of freeze-drying curve were analyzed. The influence of the temperature decreasing rate,the vacuum,the temperature of heating plate and the temperature of condenser to the process and the product quality of freeze-drying was compared.This paper is helpful to the practical freeze-drying production.更多还原
