The Industry Biomass Rotary Dryer is a high-efficiency drying machine designed to reduce the moisture content of materials like wood chips and rice husks to 8%–12%, with capacities ranging from 400 to 2000 kg/h.
We offer two types of biomass dryers: the rotary dryer, ideal for large-scale operations, and the airflow sawdust dryer, suitable for smaller, faster drying needs. Both are widely used in charcoal production, wood processing, and paper-making, helping to prepare raw materials for briquettes, pellets, furniture, and more.
Raw materials for the industry biomass rotary dryer
The industry biomass rotary dryer is designed to process a wide range of biomass materials commonly used in briquette production. Suitable raw materials include wood chips, rice husks, coconut husks, wheat straw, and other agricultural or forestry residues.
Once dried, these materials reach the ideal moisture level for direct feeding into machines à briquettes de sciure de bois, enhancing combustion performance and forming quality. This makes the industry biomass rotary dryer a key component in sustainable biomass fuel production.
Structure of industry biomass rotary dryer
- Main components. Includes drying cylinder, connecting pipes, heating furnace (installed by customer), fans, feeding and discharging systems.
- Barrel design. The drum is angled to tumble materials for better contact with hot air and efficient drying.
- Feeding and discharging system. Equipped with inlet and outlet parts, plus sealing plates to prevent material leakage.
- Heating furnace support. Manufacturer can assist with design and provide installation drawings.
- Optional cooling equipment. Can be added for high-output needs to support further processing.
How does the industry biomass rotary dryer work?
- Heat source. The heating furnace generates hot air as the primary heat supply.
- Air circulation. A fan delivers the hot air from the furnace into the dryer barrel.
- Material movement. Moist biomass enters the drum and advances via a densely packed toothed belt.
- Drying process. The material is exposed to high-temperature airflow during movement for effective moisture removal.
- Discharge temperature. The dried material exits at around 40–50°C.
- Cooling option. Larger machines can be equipped with cooling systems to reduce the temperature of the final product.
Industry biomass rotary dryer advantages
- Capacité de traitement élevée. Supports large-scale drying with low fuel consumption and reduced operational costs.
- Durable structure. Adjustable center tugboat and rolling ring design reduce wear and save power.
- Stable operation. Equipped with a block wheel structure to minimize horizontal thrust and enhance equipment stability.
- Rapid drying. Handles high-temperature airflow for efficient moisture removal.
- Flexible scalability. Designed with expansion margin—no need to replace equipment for moderate output increases.
- Efficient heat use. Optimized lifting plate layout ensures even drying and high thermal efficiency.
- Low maintenance. Fewer material cleanings and easy upkeep.

Airflow sawdust dryer for sale
The airflow sawdust dryer is a cost-effective drying solution that uses high-temperature airflow to rapidly reduce moisture content in raw materials. Wet biomass such as rice husk or sawdust is mixed with hot air and dried during transport through the drying tube.
A separator then removes moisture from the material efficiently. Ideal for industries like wood processing, feed, chemicals, and pharmaceuticals, this dryer handles materials with moisture below 30% and is widely used due to its simple structure and affordable price.
How does the airflow sawdust séchoir machine work?
- Préparation du matériel. Biomass materials like wood, bamboo, or straw must be crushed into sawdust (≤5mm) before drying.
- Hot air generation. A front-end ignition stove produces high-temperature airflow, similar to a rotary dryer system.
- Material feeding. Wet sawdust is introduced into the drying pipe by the fan’s suction force.
- Processus de séchage. As the material flips and moves through the pipes, it fully contacts the hot air, enabling rapid moisture evaporation.
- Discharge. Dried particles exit through the dust collector, completing the drying process.
Airflow drying machine advantages
- Raw material requirements. Suitable for granular materials like rice husk, sawdust, shavings, and crushed branches (≤3mm diameter, ≤5mm length).
- Drying efficiency. Dries material from 35% to 10% moisture with hot air at ≥180°C; discharge temperature: 40–50°C.
- Fuel options. Compatible with wood chips, coal, steam, electricity, or gas heating.
- High performance. Features strong drying capacity, compact size, low investment, and fast operation (2–10 seconds).
- Product quality. Minimal heat impact on material, ensuring less pollution and better quality.
- Flexible configuration. Supports multiple heating methods to match different site conditions and processing needs.

Application de machine de séchage dans les lignes de production
Once sawdust is dried and moisture is removed, it becomes suitable for further processing in various biomass production lines. We offer two main solutions:
- Ligne de production de blocs de palettes en bois. This line includes a wood crusher, drying machine, glue mixer, and block forming machine—ideal for creating durable pallet blocks from dried biomass.
- Biomass briquette production line. Here, the dried sawdust is fed into a sawdust briquette press, which compresses it into fuel briquettes for heating or energy use.
Production de blocs de palettes en bois
Mettez les matières premières mélangées dans le machine de fabrication de briques de sciure de bois, et la sciure de bois est pressée en bâtons de bois à haute température et haute pression.
Ces bâtons ont une densité et une dureté élevées. Après découpe, ils peuvent être utilisés comme repose-pieds pour palettes en bois.
Fabriquer des briquettes de sciure de bois
UN machine à briquettes de sciure de bois peut presser les copeaux de bois moulus dans des bâtons de biomasse à haute température.
Each line maximizes the value of dried materials for eco-friendly manufacturing.
Conclusion
With its high drying efficiency, wide material adaptability, and customizable configurations, the industry biomass rotary dryer is an ideal solution for large-scale biomass processing projects.
