Overview
Universal Rotary Dryer SPB5-UNI Standard is designed for biomass pellet production, offering efficiency and reliability in operation.
Universal Rotary Dryer SPB5-UNI Standard – Performance and Versatility
The SPB5-UNI Standard rotary dryer is the ideal solution for the efficient drying of raw materials used in briquetting, pelletizing, and granulating. This equipment ensures a uniform and rapid drying process for a wide range of materials, including:
Straw, Alfalfa, Biogas digestate, Fermented manure, Wood chips, Grains, Sand, Other raw materials requiring drying
✔️ Ideal for the production of:
✅ Briquettes ✅ Pellets ✅ Granules (including granules for organic fertilizers)
SPB5-UNI Standard is designed for maximum efficiency, reducing the moisture content of raw materials and preparing them for optimal processing. It integrates perfectly into briquetting, pelletizing, and granulating lines, ensuring high production capacity.

Technology used since 2025
Working principle of the universal rotary dryer:
1. Industrial thermal plant using a mixed solid fuel with pyrolysis and hot air generator - constructed from stainless steel and high-temperature resistant chamotte
2. Cyclone separator for sparks and dust, electrostatic spark separator, and dust separator
3. Automated feeding hopper for raw materials*(pelleted briquettes, wood chip pellets, agro-pellets, lemm shavings) Volume - 1.6 - 3 m³
4. Three drying modes in a rotating tube with 3 spiral chambers
5. Fan, Cyclone with rotating valve with free fall
6. Control panel and automated PLC Siemens/Eaton operating program depending on the moisture content of the raw materials
7. Homogenization hopper for wet raw materials Volume 4.2 m³ - 2 units
Drying process: the wet raw material, with the help of hot air, passes through the rotating tube composed of 3 spiral drying chambers, where it mixes and loses moisture. Then, the dried raw material falls from the cyclone with a rotating valve, and the moist air is vented into the atmosphere through a fan.
Fully equipped Universal Rotary Dryer SPB5-UNI Standard:

2. Fuel storage tank 2.4 m³
3. Emergency flap for the chimney
4. Impurity separator with cyclone
5. Electrostatic separator for sparks *(Spark separator) and dust
6. Material storage tank - silo A, 4.2 m³
7. Material storage tank - silo B, 4.2 m³
8. Footpath construction
9. Horizontal collecting conveyor
10. Screw conveyor for dryer feeding
11. Solenoid valve for raw material dosing
12. Three-chamber drying cylinder
13. Support structure of the cylinder
14. Transport fan for evacuation
15. Interconnection pipes
16. Separator with cyclone
17. Material distributor - turnstile
18. Screw conveyor for unloading
19. Air and steam
20. Exhaust gases
21. Automatic ash removal
22. Electric control panel and automated command, PLC touchscreen, remote access
Control system – the entire device is controlled from a centralized switching panel with automatic adjustment, touchscreen control. After setting the necessary parameters, the rotary dryer can be fully automated, but with necessary control from the operator regarding the correctness and proper functioning of the entire assembly – Universal Rotary Dryer SPB5-UNI Standard. The electrical components mounted on the whole assembly comply with EU standards.
Optional accessories for the universal rotary dryer SPB5-UNI Standard:
Moisture sensors at the inlet and outlet
Mobile Compact Version of Universal Rotary Dryer SPB-UNI
Conclusion
Universal Rotary Dryer SPB5-UNI Standard represents a practical solution for valorizing biomass into eco-friendly fuel, with optimized efficiency and costs.
