Experiment on Microwave Vacuum Freeze Drying Equipment

Abstract:

，能耗降低55.86%。The overall structure, working principle and design points of microwave vacuum freeze drying equipment were described. A detailed analysis on microwave syntony cavity, microwave shielding structure and the design of glass vacuum cover was made. The specific structure and related parameters of main working parts were determined. The study on freeze drying of winter Chinese date showed that the equipment had the characteristics of rational structure, stable performance, and safe and reliable running process. Compared to the ordinary vacuum freeze-drying technology, it could produce the same quality product while saving 40.9% drying time and 55.86% energy. 
