  The raft can be reprocessed into biomass fuel by drying and forming. What is the specific working process of the raft drying production line? What is the configuration of the raft drying production line? The shovel dryer manufacturer - Zhengzhou Dingli has a brief introduction.

  The raft drying production line has a feeding unit, a heating unit, a drying unit, a forming unit, a packing unit and a dust removing unit etc. The main process of raft drying: the raft is fed into the inner layer of the rotary drum by the feeding device. The downstream drying is realized, and the inner layer of the plate is continuously copied and scattered to realize the heat exchange by spiral traveling; then the other end of the inner layer is moved into the middle layer to perform countercurrent drying, and is continuously raised in the middle layer. Into, the two-step, one-step way of travel; then in the middle layer can fully absorb the heat emitted by the inner roller, but also absorb the heat of the middle roller, while prolonging the drying time, the material reaches the dry state here. The material goes to the other end of the middle layer and falls into the outer layer, and travels in a rectangular multi-loop manner in the outer drum. The material that achieves the drying effect quickly travels 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. In the rectangular copy board, sufficient drying is performed, thereby completing the entire drying process, and the dried raft enters the molding process to complete the subsequent work.

 

  The rafter dryer manufacturer--Zhengzhou Dingli designed the biomass drying production line processing route adopts the combination of one drying, secondary pulverization, continuous feeding and regulating feeding. 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, and meet the needs of industrialization of biomass pellet fuel. At present, Zhengzhou Dingli has launched a variety of models of raft drying production line equipment.
