Get to Know More about Wood Dryer
Sawdust dryer is important and indispensable drying equipment in the production of wood pellets or briquettes, which can dry the high moisture content of materials to be optimal (11-17%) for pelletizing. Besides, biomass materials go through dryer can improve biomass fuel efficiency of 5-15% and lower down emission.
Sawdust dryer mainly has two types. One is rotary sawdust dryer, one is pipe sawdust dryer. Rotary sawdust dryer is for the big processing capacity, and the airflow sawdust dryer is for small processing capacity.
Performance Features of Large Wood Dryer-Drum Type
1. High drying intensity: since the material is highly dispersed in the air stream. The entire surface area of the particles is entire effective area of the particles for drying;
2. Energy Saving: The consumption of large wood dryer can be lower 8% to 16% than the normal ones, with the production ratio being higher 10% to 15%;
3. High expandability: capacity margin has been designed, so it is no need to change equipment even a slight increase in production;
4. Environment Friendly: the special design hot air furnace can supply the clean hot air for the rotary dryer, and there is little dust and noise during working process;
5. Large drying capacity, heat efficiency can be more than 80% when it is free water;
Working Principle of Drum Type Sawdust Dryer
The hot air furnace supplies the clean hot air to the Rotary Dryer. The feeder screw sends the wet material into the Rotary drum. When the Rotary Drum is rotating, the lifting plates inside the Rotary Drum mix the wet material and hot air together sufficiently so that the wet material can be dried effectively by the hot air. The moisture of the wet material is evaporated into water vapor. The dried materials are discharged through the discharging hole as the product.
