Sawdust Flash DryerWhy to Dry Biomass MaterialsFresh wood log or wood sawdust contains too much moisture. In certain circumstances the moisture can be

evaporated so easily that wood materials will be shrunk,cracked,bent or even mildewed, and thus wood pellets

or briquettes density and quality will be badly affected.That’s why drying machine is necessary prior to the

pelletizing or briquetting stage. We offer two kinds of drying machines which are rotary drum dryer and pipe

dryer. Generally speaking, the proper moisture content for creating qualified pelles or briquettes is 8%-15%.

About Sawdust Flash DryerPipe dryer, known as flash dryer or air current drying machine, is not a bad choice for drying biomass materials

to the required moisture content. It is the most inexpensive type drying machine nowadays in biomass industry

but with the same drying effect as rotary drum dryer. The whole body includes air boiler, hopper, cyclone

separator, fan blower and drying column. Pipe dryer can be used for drying various types of small and light

biomass materials such as wood chips, wood sawdust, corn stalks, rice hulls, etc. with their diameter less than

3mm.

Pipe Pryer Features1. Wide application. Not only for biomass fuel producing,but for drying materials in chemical, pharmacy,building

industry.

2. Low cost, good drying effect. Invest in a little money but get considerable profits.

3. Can dry material with moisture content of below 55% and diameter of less than 3mm.

4. Low energy consumption, low noise. Easy to install and maintain.

How To Choose Air current DryerWe offer pipe dryer in two different types which are one hot air boiler dryer and two hot air boilers dryer.

For biomass material whose moisture content is less than 35%, we recommand the one boiler pipe dryer

as it can eliminate more than 20% moisture content; but for those contains 35%-50% moisture contant

material, the two boilers pipe dryer is necessary because of its powerful drying effect.

Flash Dryer Working PrincipleWet biomass materials are fed into pipe dryer by conveying device, at the same time, heated air is driven

to the dryer. Then the two are fully blended and move forward inside the whole pipes due to the powerful

fan blower suction. Moisture evaporates when the biomass materials go through all the pipe. At the

discharging hole material is released.
