Interpretation of wood chip drying process from wood chip dryer video



 Wood chip drying and biomass energy is currently widely used in the industry. What is the specific process of wood chip drying? Today, Dingli will share the video of the wood chip drying.

  Dingli Biomass Drying Production Line has crushing unit, drying, forming, dust removal and packaging unit. The wood chips are firstly fed into the inner layer of the rotary drum by the feeding device to realize downstream drying, and the paper is continuously picked up under the inner layer. The scattering is spirally traveling to achieve heat exchange; then the other end of the inner layer is moved into the middle layer, and the countercurrent drying is performed, and the middle layer is continuously advanced repeatedly, and the two-step, one-step traveling mode is performed; then in the middle layer It can fully absorb the heat emitted by the inner roller and absorb the heat of the middle roller, and at the same time prolong the drying time, and the material reaches the dry state here. The wood chips travel to the other end of the middle layer and fall into the outer layer, and travel in a rectangular multi-loop manner in the outer drum. The wood chips that reach the drying effect quickly travel out of the drum under the action of hot air, and the wet material that does not reach the drying effect cannot travel fast due to its own weight. Fully drying in the rectangular copy board, thereby completing the entire drying process, the processing route adopts a mixing process of one drying, secondary pulverization, continuous feeding and adjusting feeding, and the pellet forming fuel forming rate reaches 98. Above %, the bulk density, particle density and calorific value are high. It can realize large-scale, continuous and stable production to meet the needs of industrialization of biomass pellet fuel.

  At present, Zhengzhou Dingli Sawdust Drying Production Line has been exported to Russia, Malaysia, Morocco, Chile, Vietnam and other countries. Many projects have been built in China, and customers are welcome to come to the factory for purchase.
