Product Details

Biomass dryers use heat energy to reduce the moisture in raw materials. Drum dryers can operate at temperatures up to: 150-180°C. The moisture content of the dried wood is less than 10 per cent. Wood chip dryer is necessary equipment for drying wood. Biomass dryer is a drying treatment equipment for biomass raw materials such as wood chips, wood flour, shavings, bamboo powder and so on. It prepares for the subsequent pellet pressing, charcoal making and so on. It can effectively improve the quality and appearance of finished materials. The spreading Hebei effectively extends the drying time of the material. The whole process of negative pressure conveying increases the air volume. Both airflow dryer characteristics in one. Biomass dryer has the advantages of environmental protection, energy saving, high efficiency, small footprint and so on.

Technological Process

Biomass raw material is sent to the drum dryer through the feeding system. It passes through three drying zones: guide zone, material curtain zone and rapid transit zone. It makes full use of the heat exchange between materials and hot air. Adopt new type of lifting device and screw conveying structure. This greatly improves the heating efficiency of wet materials and speeds up the drying. The biomass material passes through the middle drying area of the biomass dryer. The area is a large-angle spiral belt structure with full-bending coping. Materials in the middle drum by the hot air and spiral belt under the joint action of rapid movement to the front section of the drum. At the same time, the heat emitted from the inner drum and the air volume of the hot air from the middle drum are exchanged. Thus the material reaches the dry state. The material enters into the outer drum, and travels through the outer drum in a rectangular multi-loop way. Thus, the material that achieves the drying effect is quickly discharged from the drum under the action of hot air. If the material does not reach the drying effect, it can not be pushed forward quickly because of its weight. The material is fully dried in this rectangular platen. Thus completing the whole drying process.

Advantageous

1. Biomass dryer adopts new type inlet and outlet structure, drying materials quickly.

2. The equipment has a compact structure, stable operation, convenient operation, and improves the thermal efficiency to more than 80%.

3. The fuel can be natural gas, liquefied gas, coal, oil and other substances.

4. Good drying performance and high drying efficiency. Drying one tonne of material consumes less than 8kg of coal.

5. The moisture of the finished product can be customised and adjusted according to customers' needs.
