Working Principle

Hot air enters the bottom of the dryer tangentially, forming a strong rotational airflow driven by the agitator. Paste-like material is introduced into the dryer by a spiral feeder, where it is dispersed under the intense action of high-speed rotating blades, subjected to impacts, friction, and shearing forces. Solid material is rapidly crushed, and it comes into full contact with the hot air, getting heated and dried. The dried material, after dehydration, rises with the hot air stream. The grading ring retains larger particles, while smaller particles are discharged from the center of the ring outside the dryer. They are recovered by a cyclone separator and dust collector. Un-dried or large pieces are flung towards the vessel wall by centrifugal force, falling back to the bottom to be crushed and dried again.
