Technology used from 2025
Working principle of the dryer:
1. Heat exchanger (Stove):
The heat exchanger (Stove) is a welded structure with an oven featuring an insulated combustion chamber.
2. Hopper with screw feeder in the dryer:
It is a welded structure - a hopper for raw material equipped with agitators driven by an electric motor.
3. Pipes and cyclones: the cyclones, pipes made of welded sheet are connected through a clamp ring.
In the drying process, cold air is heated with the help of the heat exchanger (Stove) and mixes with the wet raw material. Plant residues - hay, are dried in a few seconds. Then, the dried raw material falls through the cyclone into the briquetting press or into the homogenization hopper for dried raw materials, while the exhaust air is vented into the atmosphere.
Optional accessories for aerodynamic hay dryer DAD-0.4-0.8:
PLC Control System
Heat recovery in the heat exchanger (Stove)
Maximum level overload sensor in the hopper
Vibrating sleeve filter - exhaust fan
Conclusion
Aerodynamic Hay Dryer DAD-0.4-0.8 represents a practical solution for turning biomass into eco-friendly fuel, with optimized efficiency and costs.
