Wood Pellet Dryers

Dryer is used to dry the biomass powders like sawdust and other materials up to 40% moisture content to 15% moisture content usually required to make biomass pellets.  A complete drying system consists of two parts, one is furnace, also call heat stove, this is providing heat source for drying the material;another is dryer, the material feeding into the dryer by a screw conyor, rotory in the dryer, drying to 15% moisture content by the hot air from the furnance.

Furnace/hot air stove

The sawdust must be relatively well ground and consistent in particle size. The particles are suspended in mid air momentarily by hot air from the included Hot Air Stove which uses a portion of the sawdust or biomass as fuel, but can also burn by coal, oil, or natural gas. This dryer makes a great compliment for use with hammer mill and pellet mill.

Rotary Drummer Dryer

Drier is a cylinder and slantwise slightly, the rotate speed can be adjustable. Wet raw materials are fed into cylinder, the materials are well-distributed and dispersed after be turned over by shoveling  plate, then the materials contact with the hot air fully, the drying is acierated. Shoveling plate can be selected to meet different materials
