Principle of saw dust rotary dryer

Sawdust rotary dryer is applicable for various biomass, such as forage, grain, wood chips, chicken manure, etc. The heating medium doesn’t touch the materials directly.Inside the rotating cylinder, there is a concentric cylinder in which materials move forward. Flue gas enters the annular space between the shell and wall of inside cylinder, then enters the concentric cylinder through connecting pipe. Also, there is a different trend of flue gas. The concentric cylinder is first, then the annular space where materials go forward. To discharge the moisture released from the materials, moderate air draught by fan is necessary. However, the amount would be greatly less compared with the direct dryer. Because the air speed is slow (generally 0.3-0.7m/s), exhaust gas brings litter dust. Gas solid separation equipment is barely needed. On many occasion, we can also adopt natural ventilation to exhaust the moisture.

 Drying Temperature Technical Consultation and Test

The inlet hot air temperature could be 100- 180 °C.

The outlet hot air temperature could be 80-100°C

Mostly the temperature will be depends on the damp/wet initial moisture and special character .

Application:
1,Drying the damp /wet saw dust into optimal moisture (8-14%)for making wood briquette .

2,Drying the damp/wet saw dust into optimal moisture (8-14%)for making biomass wood pellets

3,Drying the wet wood flour into best moisture(below 3%) for making WPC products

Feature:
1. Energy saving2. Wide use for wood briquette production/For wood pellet production/For WPC production 
3. Good drying effect4. Low noise 5,Less burning fuel
