Drum Dryer For Drying Wood Raw Materials

Feb 05, 2018

Drum drying is a method used for drying out liquids from raw materials with drying drum. In the drum-drying process, pureed raw ingredients are dried at relatively low temperatures over rotating, high-capacity drums that produce sheets of drum-dried product. This product is milled to a finished flake or powder form. Modern drum drying techniques results in dried ingredients which reconstitute immediately and retain much of their original flavor, color and nutritional value.

Some advantages of drum drying include the ability of drum dryers to dry viscous foods which cannot be easily dried with other methods. Drum dryers can be clean and hygienic and easy to operate and maintain.

Drum Dryer Working Principle

Biomass materials with high moisture content are fed into rotary cylinder; shovelling plates inside the drum walls raise up materials and these materials scatter down to move in a spiral forward style. During the constant raising up and scattering down, 

biomass materials can absorb enough amount of heat, at the same time, the drying 

time is extended to achieve the best drying effects.
