Get to Know More about Wood Dryer

Sawdust dryer is important and indispensable drying equipment in the production of wood pellets or briquettes,which can dry the high moisture content of materials to be optimal(11-17%)for pelletizing. Besides.biomassmaterials go through dryer can improve biomass fuel efficiency of 5-15% and lower down emission.

Sawdust drver mainly has two types. One is rotary sawdust dryer, one is pipe sawdust dryer. Rotary sawdustdryer is for the big processing capacity, and the airflow sawdust dryer is for small processing capacity.

Rotary Wood Dryer Introduction

Rotary sawdust dryer is also known as sawdust drum dryer machine, which is specially designed for drying the wood chips, sawdust, wood pellets, wood shavings, etc. Our rotary sawdust dryer is made up of hot air stove and main rotary drum which is high efficiency in drying the wood and biomass material. It can be used for drying a wide range of biomass materials such as alfalfa, straw, sawdust, marigold,wood shavings, manioc waste, bagasse, colza cake and

leaves, etc.

Performance Features ofLarge Wood Dryer-Drum Type

1.High drying intensity: since the material is highly dispersed in the air stream. The entire surface area of the particles is entire effective area of the particles for drying:

2. Energy Saving: The consumption of large wood dryer can be lower 8% to 16% than the normal ones, with the production ratio being higher 10 to15%;

3.High expandability: capacity margin has been designed, so it is no need to change equipment even a slight increase in production;

4. Environment Friendly: the special design hot air furnace can supply the clean hot air for the rotary dryer. And there is little dust and noise during working process;

5. Large drying capacity, heat efficiency can be more than 809 when it is free water:

Unique Structure of Rotary Sawdust Dryer

Due to the unique structure of the sawdust dryer, the sawdust can be fully dried inside the rotating drum, and before going into the material conveyance pipe, the sawdust will be fully dispersed again, making the water more quickly evaporated. In addition, the baffle plate can block the impurities in the sawdust to ensure the quality of the sawdust that goes into the material conveyance pipe.

Working Principle of DrumType SawdustDryer

The hot air furnace supplies the clean hot air to the Rotary Dryer. The feeder screw sends the wet material into the Rotarv drum. When the Rotary Drum is rotating. the lifting plates inside the Rotary Drum mix the wet material and hot air together sufficiently so that the wet material can be dried effectively by the hot air. The moisture of the wet material is evaporated into water vapor.The dried materials are discharged through the discharging hole as the product.
