Air Sawdust Dryer Machine Biomass Wood Chip Drying Equipment 400 - 500 KG
1. Overview of Sawdust Pipe Dryer Machine
The sawdust flash dryer is new type design of biomass material drying equipment widely used in wood pellet plant and charcoal briquetting factory. Know 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. 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 briquetting plant.

4. 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 customer choose.
5. 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 drying effect
3. Large intensity of drying, short drying time
4. Big capacity, high thermal efficiency, energy-efficient and labor saving
5. Simple structure, small occupation area, easy to install and repair
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 hea
