Biomass waste such as sawdust, wood chips, straw, rice husks, and sugarcane bagasse is widely used for biomass fuel and pellet production. However, most of these materials contain excessive moisture when collected, making direct pelletizing difficult. Proper drying is an essential step before further processing.
Why Is Biomass Drying Important?
High moisture content can reduce pelletizing efficiency, increase energy consumption, and affect the quality of finished pellets. A suitable biomass dryer helps control material moisture, improve production stability, and prepare raw materials for fuel manufacturing.
How to Dry Biomass Waste?
For industrial production, a rotary drum dryer is commonly used to process large quantities of wet biomass materials. The typical drying process includes:
Raw Material Preparation: Remove impurities and reduce oversized materials through screening and crushing.
Biomass Drying: Feed wet materials into the rotary dryer, where hot air removes excess moisture.
Moisture Control: Adjust drying temperature and residence time according to the material and final moisture requirements.
Pelletizing: Feed the dried biomass into a pellet mill for compression and forming.
Cooling and Packaging: Cool the finished pellets before storage and transportation.
For many biomass pellet applications, the target moisture content before pelletizing is around 10%–15%, depending on the raw material and pellet mill requirements.
What Biomass Materials Can Be Dried?
Dingli biomass drying equipment can be customized for various agricultural and forestry residues, including:
Sawdust and wood chips
Sugarcane bagasse
Rice husks and wheat straw
Corn stalks and peanut shells
Bamboo shavings and other biomass residues
Different materials require different drying temperatures, feeding systems, and internal drum structures to achieve stable drying performance.
