Rotary Dryers
The rotary dryer is used to reduce the moisture content of the raw materials before pelletization. The machine is designed to work continuously and automatically, and includes a rotary dryer, screw feeder, cyclone air system, air lock and fan.
The wet material enters the dryer through the feeder in controlled quantities. A rake inside the cylinder distributes the material uniformly in the dryer for maximum exposure to the current of hot air. After traversing the length of the dryer the material is discharged through a star valve at the end with the perfect moisture content.

The rotary dryer may also require a hot blast stove as a source of hot air. The stoves fuels can be the same biomass materials—wood, wood pellets, straw, etc.—bound for pelletization.
