Sawdust (sawdust) is an organic matter with a moisture content of about 40-50%. The general moisture content after drying is required to be about 12%. Its main moisture is free water and biological water. Free water is easier to remove, while biological Water is difficult to remove. The drying process of sawdust (sawdust) mainly considers the output size, the characteristics of the finished material, the convenience of operation, and the operating cost. At present, most of the sawdust drying equipment uses airflow dryers, fluidized bed dryers and drum dryers. Airflow dryers and drum dryers are widely used in wood chip drying. Airflow dryers require less investment, especially when the output is small. Due to the short drying time of the airflow dryer, and the thickness cannot be classified, the moisture from the drying is easy to be unstable, and it is prone to clogging, and the operation is unreliable, resulting in the failure of the rear equipment, resulting in a waste of investment and energy.



Product Introduction
According to the market demand, the development of raw material fuel dryers. This equipment is suitable for drying biomass materials such as wood chips, sawdust, bamboo chips, wooden chips, shavings, and straw. Our company can optimize the drying process technology according to the characteristics of each biomass material, output size, application requirements, cost control, and ease of operation.

working principle
The working principle of the sawdust dryer: the material first enters the inner layer of the rotary drum from the feeding device to achieve downstream drying, and is continuously picked up and scattered under the inner layer of the copy board to achieve heat exchange in a spiral manner; then move to The other end of the inner layer enters the middle layer for countercurrent drying, and is continuously raised in the middle layer, showing a two-step forward and one-step travel mode; then the middle layer can not only fully absorb the heat emitted by the inner drum, but also absorb The heat of the middle drum also prolongs the drying time, where the material reaches a dry state. 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 achieve the drying effect cannot travel quickly due to its own weight. , Fully dry in this rectangular copy board, thus completing the entire drying process.

 According to the characteristics of sawdust materials, the dryer has been technically modified on how to improve the filling rate of materials and the residence time of materials in the cylinder. The combined material lifting device and multi-layer sleeve structure are adopted to make the materials have no wind tunnel phenomenon. The wood chips can fully exchange heat and dehydrate; and increase the coarse and fine particle separation device, which improves the heat utilization rate and also increases the output.
