Not only in China, wood chip biomass fuels continue to grow, but in the United States, the wood chip industry is also a bright future. The woody biomass industry has entered an optimistic period. The wood chip dryer industry has also grown in tandem with the benign development of woody biomass

  Wood processing waste such as wood chips, sawdust, hibiscus, shavings, bamboo chips, etc., generally have a certain water content, and this 40% to 50% of the water is enough to make the wood chips spoil, and many process requirements for wood chip recycling processing The moisture content of wood chips is between 15% and 30%. The excessive moisture will affect the quality of processed products. If the quality of wood chips is compromised, the combustion value and combustion efficiency of fuel will decrease, which will affect the creativity of sawdust.

  Sawdust dryer mainly utilizes the principle of heat exchange, and the wet wood chips and the hot air flow are fully contacted under the action of the dryer structure, and the evaporation dehydration and drying are realized under the action of high temperature. The wet wood chips are spirally moved to the middle layer at the other end of the inner layer at the same time as the initial heat exchange. At this time, the countercurrent drying is carried out, and the material is continuously advanced in the middle layer, and the two steps are carried out. Taking a step back, the material in the middle layer not only fully absorbs the heat emitted by the inner roller, but also absorbs the heat of the middle roller to achieve the best dry state. While moving to the other end of the middle layer and falling into the outer layer, the material travels in a rectangular multi-loop manner in the outer drum, and the material that achieves the drying effect rapidly travels out of the drum under the action of hot air, and the wet material that does not reach the drying effect cannot be self-weighted. The material travels quickly and the material is sufficiently dried in the rectangular copy board to complete the drying.

  Sawdust after dewatering by the wood chip dryer or the wood processing waste such as sawdust, hibiscus and bamboo powder can generally have a water content of about 12%. The specific dry material water content standard is determined by the customer's processing technology requirements. The dried wood chips are improved and improved both in terms of processing availability and storage and transportation. Therefore, the rise of the woody biomass industry will inevitably lead to the development of sawdust dryer industry.
