Sawdust drying as a pellet fuel is one of the main ways to use wood chips as a resource. The finished wood pellets have good quality, sufficient fuel combustion and high calorific value. Zhengzhou Dingli has been a manufacturer of 15 years, customizing and supplying sawdust dryers and complete set of biomass pellet production line. What is the working principle of the sawdust dryer? What is the price of wood pellet drying equipment? This article introduces you in detail.

  Working principle of sawdust dryer

  Dingli sawdust dryer is mainly based on three-layer drums. The material first enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. Under the inner layer of the copy board, it is continuously picked up and scattered in a spiral travel type to achieve heat exchange; Then move to the other end of the inner layer and enter the middle layer for counter-current drying. In the middle layer, it is continuously raised repeatedly, showing a two-step forward and one-step travel mode; The material in the middle layer can not only fully absorb the heat emitted by the inner drum, but also absorb the heat of the middle drum, and at the same time extend the drying time, the material reaches the expected dry state here. The material travels to the other end of the middle layer and falls into the outer layer. It travels in the outer drum in a rectangular multi-loop manner. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not reach the drying effect cannot travel quickly due to its own weight. The rectangular slab is fully dried to complete the entire drying process.

  Sawdust drying pellet fuel production equipment price

Sawdust drying pellet fuel production equipment consists of heating system, crushing system, transportation system, drying system, pelletizing / briquetting system, dust removal system, power distribution cabinet, etc. The equipment models are complete and the production capacity is not limited. And the production line configuration is divided into simple configuration, standard configuration, and high configuration. Therefore, the price of the wood pellet drying pellet fuel production equipment needs to be calculated according to the capacity and production line configuration.
