Sawdust Dryer

Sawdust dryer is used for pellet sawdust or powder sawdust. Wet materials are continuously sent into the drum through a screw conveyor and then get separated and pushed by the high-speed hot flow. The moisture in wet materials is taken away in this process and then we get powder or pellet dry materials.

• Capacity: 1.5-12 t/h
• Dried Moisture(%): 12-15% (Adjustable)
• Heat Source:biomass, natural gas, diesel, coal, etc.
• Application:Widely used for drying sawdust, wood chips, pasture, wood shavings, straw and other materials etc.

What is Sawdust Dryer?

Sawdust dryer is one type of rotary dryer that is specially designed for drying sawdust, wood chips, straw and charcoal, etc. It has high drying intensity, short drying time, large production capacity, high efficiency, small occupied area, easy operation and maintenance, etc. It is also known as sawdust drying machine or sawdust rotary dryer. Mainly, there are two types of sawdust dryer machine named as airflow sawdust dryer and three-channel dryer. The latter is generally used in the sawdust drying process.

Applications of Sawdust Rotary Dryer

Sawdust refers to as the dust, chips, shavings and other materials left when wood is processed. Dried sawdust is widely used as fuel, filler, etc. As a result, sawdust dryer machine is also applied to many fields as follows:

Fuel processing: dried sawdust when briquetted is the key raw material in the fuel industry, like in heating supply system, power plant and so on;

Furniture industry: sawdust rotary dryer is used to dry the wet sawdust to a certain humidity, which is for the shaving board making, plywood making, etc. 

Paper Making Industry: dried sawdust can be the raw material when make paper, therefore, this sawdust drying machine plays an initial part;

Edible fungus cultivation: the sawdust which is dried to the required moisture can be to cultivate mushrooms, fungus mushrooms, needle mushroom and agaric mushroom.

Structure and Benefits of the Sawdust Dryer

Sawdust Dryer is mainly composed of a heating furnace, inlet, rotating cylinder, filtering cylinder, conveying pipe, cooling tube and the outlet.

Small occupied area, easy construction and maintenance, low drying cost. The material is highly dispersed in the airflow dryer; the particle surface is the effective drying area;

Strong drying strength, short drying time, high processing capacity, high thermal efficiency, non-binding water heat efficiency is up to 60%;

Wide scope of applications. The operating parameters can be changed according to the requirements of different customers;

Long service life. The cylinder rolls stably, thus, wearing is reduced.

Working Principle of Sawdust Dryer

1. The sawdust is fully dried in the rotating cylinder;

2. Sawdust is fully dispersed again before entering into the material conveying pipe, so that the evaporation will be faster;

3. The material is boiling in the tube, the hot air and material will fully contact with each other to complete the drying process.

How to Improve the Efficiency of Zoneding Sawdust Dryer Machine

Faced with numerous changes and threats, Zoneding keeps on the research of how to increase the efficiency of the sawdust dryer and finds some tips.

1>> Replace the spiral conveying blades at the feeding end with 6mm steel triangular stiffened plates. It is to lower the sawdust speed in the high-temperature zone and to make a maximum utilization of the heat. 

2>> Build central X-shaped lifting blades to prolong the residence time of the material and improve the heat transformation;

3>> Change the angle of the feeding tube. With the standard of not to influence the feeding efficiency, lift the blanking cylinder as much as possible. The top of the lifted tube shall not touch the material retaining ring. The part of the tube inside the cylinder shall be not too long and the material falls within the 200mm of the retaining ring. Thus, a material screen is formed and heat transformation is enhanced.
