Range of application

Three layer efficient energy-saving rotary drum dryer, based on the tradition high moisture content dryer and improved by our company after absorbing international advanced technology , is a kind of modern high efficient and energy-saving rotary drum dryer. This technology has reached the international advanced level now through melioration, which can process not only low viscosity and high moisture content material but also those high viscosity materials. This machine is suitable for drying a variety of lees and residue materials which moisture content is less than 85%, such as brewery grains, alcohol lees, marc, dregs, starch pulp, livestock manure, slaughter waste etc, it get excellent effect to open up feed resource , reduce feed cost and phase down environmental pollution

mechanical structure and work principle

The materials are fed by feed device into the inner layer of the rotary drum where downstream drying is achieved. The materials is shoveled

and dispersed by lifting plate to do heat exchange in screw movement

forward. The material move to the another end of inner layer and enters

to the middle layer where counter flow drying is realized, and the material is winnowed repeatedly and make its way two steps forward and

one back. During this period, materials can fully absorb the heat given by

Both the inner and middle revolving cylinder, meanwhile, the drying time is extended, which can make the material perfectly dried. The materials

moves to the end of the middle layer and falls into the out layer, where

The material make it way inform of rectangle multiple chains, and finished drying material moves rapidly and is discharge out of the drum

under the action of the heat wind, while the moisture material can’ t move

fast because of deadweight, and is fully dried inside the rectangle lift plate.
