(1) Introduction
RWGF microwave/hot-air low temperature roller kiln is mainly used in dehydration of large workpiece 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 30%.

(2) Structure 
RWGF microwave/hot-air low temperature roller kiln consists of microwave attenuators, microwave/electric hybrid heating zone, quenching zone, feeding device, discharging device, 90o bending devices, transmission line, electric control system, temperature and moisture control system, microwave feeding system, etc.
