Three-layer Rotary Drum Dryer Introduction
The three-layer drum dryer, is the famous product designed and developed by our company, to reduce the floor space and improve the efficiency of the dryer. The rotary drum consists of three parts: the inner cylinder, the middle cylinder and the outer cylinder.  This system has reasonable design , stable performance, advanced technology, high output, low energy consumption, good drying effect and high degree of mechanization. Three-layer rotary drum is suitable for the treatment of high-humidity materials.

Three-layer Rotary Drum Dryer Working Principle
The wet material is fed into the inner layer by the feeding device to achieve downstream drying. Under the lifting board and hot air flow, the material moves to the other end of the inner layer, and enters into the middle layer, begin upstream drying with the induced fan, then the material goes to the other end of the middle layer and falls into the outer layer. When the material that achieves the drying effect quickly moves out of the drum under the action of hot air.

Three-layer Rotary Drum Dryer Advantages
Compared with the single-drum dryer, the length of the machine is shortened by 50%, reducing the building area and saving about 40% project investment.
The hot air stove can be equipped with various heating source.
The equipment has large processing capacity, strong anti-overload capability, low energy consumption, and can directly reduce the drying cost.
The use the latest drying technology, greatly improving the thermal efficiency.
