Aerodynamic Double-Circuit Sawdust Dryer SA-800 PRO

SA-1200 is our most efficient double-circuit aerodynamic dryer. It is capable of drying up to 1200 kg of material per hour!

This is a professional set of machines for drying fine-fraction raw materials: sawdust, wood chips, straw, and grain waste.
It is used to prepare them for subsequent pelletizing, granulation, or briquetting. All this can be done within a single technological line – it can be connected to our pellet production lines.

SA-1200 is an aerodynamic pipeline, inside which a stream of hot air circulates. The source of heat is a chamotte (fireclay brick) furnace, to which a pellet burner can also be purchased. To install it, you only need to replace the furnace door.

The aerodynamic dryer operates using a fairly simple mechanism. Plant-based raw material is dried in an aerodynamic pipeline through which a stream of heated air passes. Thanks to the high temperature, moisture from the outer layer of the raw material evaporates, while the moisture inside migrates to the surface—this method of operation limits the risk of ignition. The heat is provided by a connected wood-fired furnace or a pellet burner (available separately), such as DOMNA-350.

This model is an excellent supplement for the LDG-3000 DUO granulation line and the LDG-4000 DUO.

The dryer can be used to dry the following materials:

-  hardwood and softwood sawdust

-  wood chips

-  straw

-  grain waste

Stages of the sawdust dryer operation:

1. The raw material is loaded into the feeding tank.
2. Heated air, called the "drying medium," is supplied through the pipeline.
3. The sawdust is conveyed through the pipeline together with the “drying medium.”
4. Under the influence of high temperature, moisture from the outer layer of the raw material evaporates, while the moisture from the inside migrates to the surface.
5. This process, along with the optimal temperature, prevents the ignition of material particles.

After completion, the sawdust reaches the proper moisture level for pellet production. Fuel pellets can be produced for the needs of farms, enterprises with their own boiler rooms, residential buildings, bathhouses, and saunas.

The Aerodynamic Dryer SA-1200 set includes:

• Metal housing for the brick-built chamotte furnace (made with 1620 bricks);
• KPS-600 Screw Feeder-Calibrator – its main task is to calibrate and screen the raw material by removing bark, pieces of wood, branches, and waste, as well as ensuring even feeding to the dryer pipelines;
• Pipeline system: in this part of the dryer, the raw material is dried as it passes through the pipelines;
• 2 centrifugal dust-proof fans: circulate hot air with the raw material through the pipelines.
• 2 cyclones: used to clean gases of solid particles;
• Control panel. The electric control cabinet includes remote automatic control devices for the mechanisms and electric drives of the set, mounted in the control cabinet;

The equipment is delivered disassembled (which allows for easier transport and optimal use of space) and must be assembled by the user.

Assembling the dryer is a key process. We recommend consulting our customer service specialist. Professional technical support will help resolve any issues and ensure correct installation, which will affect the efficiency and durability of the dryer.

The furnace bricks are not included in the set!

Advantages of the SA-1200 Sawdust Dryer

• Versatility – allows drying of various plant materials, including sawdust (softwood and hardwood), wood chips, straw, and grain residues.
• High productivity – capacity to dry up to 1200 kg/h, which meets the needs of industrial operations.
• Efficient drying – fast and precise moisture removal from light and finely chopped raw materials (from 60% down to 6–12%), which significantly reduces material preparation time for further processing.
• Modern double-circuit system – design reduces the risk of material ignition by controlling temperature and ensuring optimal air circulation.
• Easy operation – after initial setup, the operation is largely automatic; the control panel and safety systems allow accurate monitoring of the drying process.
• Energy efficiency – the device is characterized by low energy consumption thanks to its connection with the furnace, which reduces operating costs.

Bonus: digital laser thermometer and grease gun included
