4.     Suitable for materials which are sensitive to heat; can run under reduced pressure environment;


Working principle:
Rotary drum dryer makes liquid or other slurry materials form a thin film on the surface of rotary drum heated by steam and other heat carrier. Materials will be dried after one circle rotation of drum. Then, use scraper to separate materials from rotary drum. Then, clean surface of rotary drum will contact with raw materials again and form a thin film in order for further drying step.

Introduction
Drum scraper dryer is a kind of rotary continuous drying equipment which is characterized by internal heating mode. Rotary drum will pass through lower feed chute where a layer of material film which holds a certain thickness adheres to. Heat is conveyed to inner wall of rotary drum by pipe and then conveyed to external wall. Then, heat will be conveyed to material film, which will make moisture content in materials evaporated and dehydrated. Materials which have been dried will be put on scraper which is on the surface of rotary drum. Then, materials will be sent out from rotary drum to a conveyor which is located under the lower part of scraper. Finally, materials will be collected and packed through screw conveyor.
