(1) Introduction
RWFD microwave/hot-air low temperature conveyor dryer is mainly used in dehydration of powder materials under air atmosphere. Depend on the user’s actual demand, it can choose either pure microwave drying or microwave/hot-air drying. In comparison to the traditional dryer, our dryer’s structure is simpler, larger in capacity, smaller foot-print, higher efficiency, and save energy over 40%.

(2) Structure
RWFD microwave/hot-air low temperature conveyor dryer consists of frame, microwave cavity, drives, belting, microwave feeding system, moisture extraction system, circulating cooling water system, belting rectification and tension device, electrical control system, hot air piping or heat exchanger, etc.
