Abstract

Microwave concentrating device on fresh apple juice is designed in order to increase concentrating fresh apple juice efficiency and microwave concentrating process on fresh apple juice were studied. The designed microwave concentrator contains microwave generator, dehumidification system, electrical cabinet, parabolic waveguide, control system, microwave leakage inhibited mechanism and other components. The concentrating experiment is carried by the designed concentrator, from the setting-to-work test, the design was success.

Keywords:

Microwave concentrating, microwave concentrator, microwave control system, microwave power generator,
