The sawdust flash dryer also called pipe dryer or flash dryer, this machine is designed for drying materials like sawdust, wood shaving, wheat straw, and corn stalks, paddy straw , etc. Lower cost for input, so this machine is hot-sales in the wood pellet and briquette production line.
Hot Air Circulation Sawdust Dryer
The sawdust flash dryer also called pipe dryer or flash dryer, this machine is designed for drying materials like sawdust, wood shaving, wheat straw, and corn stalks, paddy straw , etc. Lower cost for input, so this machine is hot-sales in the wood pellet and briquette production line.
Working Principal of Hot Air Circulation Sawdust Dryer
Air flow is formed through the negative pressure of blower, the material enters into the pipe through the screw feeder, so that the hot air and material mixing together, so the moisture is separated from the material during passing the cyclone to make the effect of drying material.
Air-Flow Dryer
Features of dryer for sawdust:
1. Strong strengh for drying: Air flow with high speed, inner side with large effective area, so materials can be dried very well.
2. Short drying period: the period that materials exposed to hot-air is very short, in general, drying time is between 0.5-5 seconds.
3. High thermal efficiency: this types air flow dryer adopts Airflow drying material with gas and flow operation, from beginning to end material can achieve reasonable state temperature and air temperature, drying time is short, so can use high drying temperature.
4. fuel optional by Oil burner, coal stove, gas furnace, pellet, wood, steam heat exchanger.
5. widely application scope, low cost for investment and maintenance. Model | Moter power (kw) | (T/H) |

What is the working principle of airflow dryer?
Raw material goes into the furnace through the inlet pipe, conveyed into the cyclone under the function of fan. Dried material come out from cyclone, waste heat, waste vapor is discharged from upper cyclone.
It is must be dried when produce biomass pellets?
Whatever sawdust, moisture should be controlled in a range. It is shapeless if raw material too dry, loose with low moisture. The best humidity for pelletizing is between 8%-12%.
Which kind of heating sources can be used?
firewood , gas, electricity, wood pellet, etc can be used as heat source.
