Rotary Dryers

Rotary Dryers are considered as “work horses” and associated with high product handling rates.
The rotary dryers consist of an inclined long drum (cylinder), rotating slowly, through which the material (particles or grains) flows with a tumbling action in co-current or counter-current flow with the heating air/gases. Flights on the cylinder wall lift and cascade the product through the air. In a variant, louvers are used instead of flights so that the product is mixed and rolled instead of dropped. The dryer is typically sloped, so that the product enters and gradually falls toward the discharge end.
