Rotary Dryers - FEECO International Inc.

Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air,การอบแห้งวัสดุทางการเกษตรด้วยเครื่องอบแห้งแบบโรตารีร่วมกับ,,The combined rotary dryer and stepwise infrared radiation was proposed and studied in this project to reduce energy consumption in the drying process.
