The straw dryer produced by Dingli Group is widely used in corn straw drying, soybean straw drying, wheat straw drying, high mast drying, wood chip drying, sawdust drying and other agricultural cellulosic materials drying. The equipment can use convective heat transfer by hot air or heat transfer by steam. The drying speed is fast, the drying strength is large, and the residence time is short. Fully automatic control, stable and reliable operation. The coal-fired system adopts a fuzzy controller, and the temperature can be automatically adjusted to ensure the quality of the dried product.

Dingli straw dryer work process: 

  The wet straw enters the drum via a feeder and a feed screw conveyor. Hot air and wet straw enter from the head of the dryer at the same time, and run backwards and exit from the tail, which is called a downstream drying process. In the cylinder, the material is in full contact with the hot air for wet heat exchange. The high temperature air transfers the heat to the wet material, so that the temperature of the wet material rises, the wet material heats up, and the water content evaporates and is discharged into the hot air to achieve drying of the wet material.
