Aerodynamic Sawdust Dryer SA-400

Aerodynamic Sawdust Dryer SA-400 is a modern moisture removal device for fine-fraction plant-based materials, including sawdust, shavings, straw, and grain waste. It is used when preparing feedstock for pelletizing, fuel production, or further processing.

Aerodynamic sawdust dryer uses a proven operating principle: the material is dried in a pipeline system through which a stream of hot air flows. Under controlled temperature, moisture from the surface of the feedstock evaporates, and internal moisture migrates outward—this process ensures safe dewatering. The heat source is a firebox or a pellet burner mounted in the connected masonry furnace (the burner is not included and must be ordered separately). The unit integrates perfectly with pellet production lines and other processing systems.

In combination with a pellet production line, it provides a complete package for pellet manufacturers.

Advantages of the SA-400 sawdust dryer

• Versatility – enables drying of various plant-based materials, including sawdust (from softwood and hardwood), shavings, straw, and grain waste.
• High throughput – drying up to 400 kg/h, meeting the needs of most pellet production facilities.
• Precise drying – rapid and even reduction of moisture content in fine-fraction materials (from 60% down to 6–12%), significantly shortening the time needed to prepare the feedstock for subsequent processing stages.
• Advanced two-chamber system – the design reduces the risk of material ignition by controlling temperature and ensuring proper air circulation.
• Easy operation – after calibration, the process is partially automated: the control panel and safety sensors provide precise control of the drying process.
• Energy efficient – the dryer features low power consumption thanks to its connection with the furnace, which reduces operating costs.

Our aerodynamic dryers are supplied disassembled, which allows for easier transport and optimal use of space. Assembling the dryer is a critical process. We recommend consulting our customer service specialist. Professional technical support will help resolve any issues and ensure proper installation of the dryer, which will improve its efficiency and longevity.

Applications of the SA-400 tubular sawdust dryer

The SA-400 aerodynamic sawdust dryer is a good choice wherever fast and efficient drying of plant waste is needed. The dryer is used in the wood and energy industries, as well as in the agricultural sector and pellet manufacturing companies.

The sawdust dryer is used to dry the following raw materials:

- sawdust from hardwoods and softwoods;

- shavings;

- straw;

- grain waste.

Our equipment enables the production of fuel pellets with a density of 1–1.3 g/cm³, offering high combustion efficiency and heating value. The aerodynamic sawdust dryer helps produce environmentally safe products from wood industry waste.

The sawdust dryer processes raw materials with a particle size up to 7 mm.

Fresh wood sawdust with 40–60% moisture and below is dried and prepared for pelletizing after a single pass through the dryer.

Operating stages of the sawdust dryer:

1. Feedstock is poured into the calibrator above the feed hopper.
   
2. At the same time, hot air—often called the “drying agent”—is blown into the pipeline.
   
3. Together with the drying agent, the feedstock is conveyed through the pipeline.
   
4. Under high temperature, moisture from the surface evaporates and internal moisture migrates toward the surface.
   
5. This process, together with properly selected temperature, prevents particle ignition.
