Working principle of the dryer:
1. Heat generator - construction made of steel and high-temperature resistant refractory.
2. Raw material feeder tank Volume - 1.6 - 3 cubic meters with screw dosing in the dryer.
3. Rotary tube with 3 drying chambers in a serpentine shape.
4. Fan, Cyclone with a rotary valve with free fall.
5. Control panel and automated operating program via Siemens LCD based on the moisture content of the raw material.
The drying process: the wet raw material, using hot air, passes through the rotary tube composed of 3 drying chambers shaped like serpentines, where, mixing, it loses moisture. Then, the dry raw material falls from the cyclone with the rotary valve, while the moist air is vented into the atmosphere by the fan.
Optional accessories for rotary sawdust dryer SPB-5:
Industrial chip separator
Remote control internet connection
Moisture sensors for input and output flow
Version of the mobile rotary dryer
Conclusion
Rotary sawdust dryer Series SPB-5 represents a practical solution for valorizing biomass into ecological fuel, with optimized efficiency and costs.
