Why Need Sawdust Dryer for Bio Pellets Production?
To get the superior quality of biomass pellets or briquettes with high density, it is necessary to control the moisture of material at 8-12% exactly before the sawdust is fed into the wood pellet mill. Actually, this moisture content of your sawdust will be a little higher or lower. Too high moisture content in your sawdust will make your wood pellets production failed, and then the wood pellets or wood briquette will be in low density and easy to be broken. Our airflow sawdust dyer makes a great compliment for use with a small wood hammer mill and wood pellet mill.

Airflow Sawdust Dryer Introduction

small sawdust drying machine

The airflow sawdust dryer, also called pipe dryer or flash dryer for sawdust , is professionally designed for drying materials like sawdust, rice hull, wood chips, wood shaving, wheat straw, and corn stalks, paddy straw , etc. Moisture in the raw materials of less than 40% can be drying one time to meet the requirement for wood pellets production. In addition, airflow sawdust dryer is considered as the most inexpensive sawdust dryer, which is highly recommended for bio-pellets production capacity less than 1000kg per hour.

Features of Air Current Dryer

1. This airflow dryer can reduce the moisture of the materials to 8-12% one time with the advantages of lower consumption and high efficiency.
2. Moisture evaporative power can be from 50kg/h to 1500kg/h.
3. The pipes of dryer can be changed to any angle based on the production field, less floor area and easier installation.

Sawdust Flash Dryer Application

Airflow sawdust dryer is widely used in wood pellet fuel, straw briquette fuel, charcoal machinery, sawdust briquettes, and agricultural engineering industries. For example, the drying of agricultural fiber materials such as corn straw, soybean straw, cotton stalks, wheat straw, sorghum stalks, sawdust , wood shavings, ginkgo leaves, mulberry leaves, etc.

Working Principle of Small Sawdust Dryer
Use one screw conveyor to send the wet sawdust into the airflow drying tube continuously. The fuel boiler generates hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air is flowing and going through the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock.
