Alfalfa rotary dryer Overview
Product Introduction
 
The three-layer drum dryer is a new type of drying equipment developed by Zhengzhou Dongding Dryring Equipment Co., Ltd. to reduce the floor space of drying equipment and improve the efficiency of the dryer. The dryer consists of three parts: the inner cylinder, the middle cylinder and the outer cylinder. System design Reasonable, well-produced, stable performance, advanced technology, high output, low energy consumption, small footprint and high degree of mechanization. After the improvement of applicability of our technical personnel, the effect is very good in the treatment of high-humidity materials.

Working Principle

The wet material is fed into the inner layer of the three-layer drum by the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the copying board in the inner layer and spirally conveyed to achieve heat exchange. The material moves to the other end of the inner layer and enters. In the middle layer, counter-current drying is performed, and the materials are continuously raised in the middle layer. This is a two-step progress. The material in the middle layer not only fully absorbs the heat dissipated by the inner drum, but also absorbs the heat from the middle drum while prolonging its drying time, the material in this state will achieve the best dry state. The material goes to the other end of the middle layer and falls into the outer layer. The material in the outer drum is in a rectangular multi-loop manner. The material that achieves the drying effect quickly moves out of the drum under the action of hot air. The wet material that does not reach the drying effect cannot be fast due to its own weight. The material is fully dried in this rectangular copying board to achieve a drying effect and the drying process is completed. Dust-laden dust discharged through the dust collection equipment to collect dust.

Product Advantages

1.Compared with the single-drum dryer, the length of the machine is shortened by 50%, which is advantageous to the process layout, reducing the building area and saving about 40% project investment.
2. The hot air stove can be equipped with boiling furnace, spray coal stove, hand-fired stove, biomass fuel hot air stove, also used for fuel, gas stove, can bake a block of less than 20mm, granular material, powder, slurry-like materials.
3.The equipment has large processing capacity, strong anti-overload capability, low energy consumption, and can directly reduce the drying cost;
4. The use of co-current, counter-current, mixed flow and other drying technology, greatly improving the thermal efficiency;
