Rotary Drum Dryers

Rotary dryer is the choice for high throughput capacity applications involving high moisture, friable, free-flowing commodity products and by-products. A rotating drum and strategically positioned flights combine to lift and shower products evenly through the air stream. Thermostatically controlled discharge air temperature assures precise final moistures and great sensitivity to varying product conditions. Single-pass or three-pass configurations are available to match with product characteristics. Heating options include steam, gas, oil, thermal oil and other auxiliaries.


After the damp raw material is put into the dryer from one end, it is turned over through string-up rake inside the cylinder and distributed uniform in the dryer and contacts with countercurrent hot air fully. It speeds up heat and mass conducting of dry. During the period of drying, raw material is affected by stirring-up rake’s gradient and hot air. It can move and pass through the dry region to star valve and then discharge the finished product.
