Pipe Biomass Dryer Air Flow Pipe Wood Sawdust Dryer

Product Description

Pipe Biomass Dryer Air Flow Pipe Wood Sawdust Dryer

Introduction of Sawdust Dryer:


1)Drying is important before Briquette process.It is necessary to control the moisture of material at 8-12% exactly.In order to get superior quality of biomass briquette with high density.
2)The selection of dryer model depends on the original moisture content of raw materials.
3)Wood dryer is suitable for drying materials like sawdust,rice hull,milling wheat straw,corn stalk etc.Raw materials size:<1mm&<5mm.

Description of Sawdust Dryer

Pipe dryer is very important for further briquetting/Pelletizing process. To get the superior quality of biomass with high density, it is necessary to control the moisture of material at 8-12% exactly. The selection of drying plant models depends on the original moisture content of raw materials.

The Advantage of Wood Dryer:
1. Strong drying strength: high aire flow speed, the material can disperse well.
2. Air drying time is short:  drying time is about 0.5 to 5 seconds, the heat sensitivity or low melting point material will not cause overheating or decomposition to affect its quality.
3. Airflow dryer has high thermal efficiency: airflow drying material and air flow cocurrent operation,  the material and air temperature can reach a reasonable state, the drying time is short, which can use a higher drying temperature.
4. Wide range applications, high yield, large precipitation; simple structure, small station area, low investment and maintenance costs.
5. Air air Source:furnace, gas stove, coal stove, steam heat exchanger.

Principle of Sawdust Dryer

In the dryer, high-speed hot air stream sustain raw material in the suspending state, then the material is dried. Since air stream speed is very high, and materials suspending in air stream, the heat transfer surface between air and raw material is large, so the heat transfer rate is high.
It can reduce moisture from 40-45% to 8-12%.
Fuel for the furnace: wood waste, coal. Waste oil and so on.

 

Raw material


It is suitable for dryingsensitive material like sawdust, rice hull, milledwheat straw, milled cotton / corn stalksand so on.
