Working Principle

 The crushed materials of which the moisture is about 35%-65% are sent into the roller by conveyor to realize downstream drying. Under the effect of the inner shoveling plate, materials are taken and scattered constantly, and move in the spiral forward method. Through three layers (inner, middle and outer layer), heat exchange is realized between material and hot air medium.

 Advantages of Biomass Dryer

 1. The three-layer rotary drum dryer has large output, high efficiency and energy saving, and a small footprint. Compared with ordinary dryers, it can save energy by 30-50%, which can maximize energy saving and drying costs.

  2. The heat exchange of the three-layer rotary drum dryer is sufficient: the material and the hot air are reciprocating and crossing to achieve heat exchange in the downstream, countercurrent, and downstream. The heat exchange time is long, and the moisture discharged from the evaporation of the material in the inner drum is directly pumped by the fan. Go, heat energy utilization efficiency is high.
