GHG and QHG dryer with heating furnace, feed port, rotating drum/ cyclic nodes, delivery pipe, dust collector and discharge port. Wet material is continuously sent to the drum tube by a conveyor. Heat air makes full contact with the material. Being delivered and scattered by the high-speed hot air, water in the wet material is evaporated. 

     The material gets fully dried in the rotating drum / cyclic nodes. The dryer is widely used in industries like biomass fuel, wood pellet fuel, sawdust briquette, farming etc. 

     The GHG type drum dryer is good for drying different kind of biomass materials such as sawdust, wood chips, straw, fibers or other small pieces of materials. But the QHG type dryer is only good for drying some powder type of materials.
