The 2014 Bauma Biomass sawdust rotary dryer, Sawdust/ Wood chips/ Bark/ Seaweed dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the biomass it is handling by bringing it into direct contact with a heated gas.
Biomass such as sawdust, wood chips, barks, seaweed and so on features:
-Heavy humidity as much as around 40%
-Flammable and combustible with high density dust during drying
-Low drying temperature required
- Light specific gravity , big volume after dry
According to above features, Henan Hongji Mine Machinery Co.,Ltd. designed new type biomass dryer

The indirect heat rotary drum drier is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow).
