ISO Approved 5.5 kw Grass Dry Saw Dust Machine With Flash Dryer
1. 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%.
2. 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 circulator 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 customer choose.

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.
7. 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.
