High Efficiency CE Approved Air Flow Dryer Sawdust Dryer Equipment
1. Overview of Sawdust Flash Dryer
The sawdust flash dryer is new type design of biomass material
drying equipment widely used in wood pellet plant and charcoal
briquetting factory. Known as pipe dryer, it is good choice for
solid raw material which has good flow ability. The suitable
biomass material moisture content for making wood pellets and
biomass briquettes is 8%-17%. This efficient wood dryer can process
material with initial moisture content below 50%.

How does the crusher machine make woog log and tree branch to
First ,The wood log diameter shall smaller than the mouth of
sawdust making machine.
Second,We put the wood log directly in to mouth of wood sawdust
machine ,with rotation blades and hammer shaft ,the log will
crushed gradually and draged into the crusher blades .In the
crushed chamber ,the wood log chipped by the blades first ,then
then the chipped wood chips hammed by the rotation hammers ,it
become smaller and smaller until it can come out from the bottom
screen get the fine sawdust.
Wood chipping first ,making sawdust second ,all of them in one
crusher chamber ,two connect process.

3. Sawdust Flash Dryer Structure and Working Principle
The whole wood drying machine mainly consists of hot wind stove,
material feeder, drying pipe, dying cyclone, cyclone separator and
controlling system. When the sawdust pass through the pipeline, the
wet moisture will be removed from the material and the dried
sawdust is discharged from the cyclone separator. This drying
machine adopts two time circulate heating system, strengthening the
heat and mass transfer rate, material moisture at 50% can be dried
into the requirement of making wood pellets/briquettes at one time,
greatly save the labor. We have two types of sawdust dryer for the
4. Remarkable Advantages of Pipeline Drying Machine
1. Adopt the hot air jet self-priming device, automatic feeding
2. Fast heat flow velocity, material is fully mixed, excellent
3. Large intensity of drying, short drying time
4. Big capacity, high thermal efficiency, energy-efficient and
5. Simple structure, small occupation area, easy to install and
5. Pipe Dryer Application
1. Drying the wet saw dust into optimal moisture (8-14%) for making
wood briquettes .
2. Drying the biomass material to the moisture (8-17%) for making
biomass wood pellets
3. Drying the wet wood flour into best moisture(below 3%) for
making WPC products
4. Essential drying equipment in wood pellet plant and biomass
6. How to Dry Material with Pipeline Drying Machine?
The pipeline type dryer uses homemade combustible gas as heating
source, drying is divided into two parts: drum part and coiled
pipe, drum part has two layers of inner drum and external
insulation layer. Inner drum is equipped with three head inner
helix slice which can move the drying aggregate in constant speed,
we call it stir-frying heating. Coiled pipe secondarily uses the
heating source, using draught fan negative pressure to pump the
drying aggregate to screw device, then separating and drying.
Why Choose Our Pipeline Drying Machine?
The dryer on the markets generally adopts coal, firewood as heating
source, high labor intensity and cost, thermal efficiency loss is
large, heat utilization is less than 30%, moisture content 35%
materials need to drying 3-4 times. Compared with the current dyer,
our new type pipe drying machine can make the moisture content 35%
of the raw material dry all at once, it can save 75% electricity to
low the cost. The combustible gas of pipe dryer is methane which is
can be in the carbonized kiln.
