Hot air enters tangentially at the bottom of the dryer, forming a powerful rotating airflow field driven by the agitator. Paste material is fed via a screw conveyor, where high-speed rotating blades disperse it through impact, friction, and shear forces. Material blocks are instantly broken down for full heat exposure and rapid drying. Dehydrated particles ascend with the hot air stream, a classification ring retains oversized particles, qualified fine particles exit through the ring center, are collected via cyclone separator & dust collector, and undried materials are centrifuged to the walls for re-crushing.
