Sawdust drying machine is widely used in straw briquette fuel, charcoal machinery, sawdust granular fuel, sawdust briquette as well as husbandry projects for dying maize straw, soybean straw, cotton stalk, wheat straw, sorghum straw, sawdust, wood shavings, ginkgo leaves, mulberry leaves and other agricultural cellulose materials.

The advantages of sawdust dryer:

1. High drying strength. As the materials are highly dispersed in the airflow, all the superficial areas of the particles are the effective drying areas.

2. Short drying time.

3. Simple structure, small floor space and easy construction and maintenance.

4. Big handling capacity and high thermal efficiency. When drying unbound water, the thermal efficiency can reach 60%.

It is generally acknowledged that 8%-12% moisture content is the best for the sawdust. Neither too dry nor too wet is good. Some people cannot handle the precise requirement and dry sawdust casually, which is not helpful for the drying effect. Here Dingli Machinery will introduce you the reason why it is necessary to dry sawdust.

As is known by the public, there is much organic and nutritious inorganic substance which is easy to produce wood rotting fungus and worms. The necessary conditions for their existing is: 1. The temperature must be 24-30。; 2. The oxygen supply must be sufficient; 3. The moisture content of sawdust must be between 30%-40%, which is suitable for the fungus to reproduce. Just because of these three reasons, we should dry sawdust reasonably and put it into production after reaching the appropriate moisture content.

Here the sawdust dryer adopts high-temperature degreasing dry method which has several functions as below:

1.Dry the sawdust and make its moisture content decrease to 8%-12% which is not suitable for the fungus to reproduce. Thus realize the goal to prevent corrosion and store conveniently.

2.Kill the worms and worm eggs through high temperature.

3.The sawdust after drying has similar moisture content with air, which could stabilize its moisture content and hygroexpansion.

4.There are many constituents in sawdust changed after being degreased under high temperature. It will also have a more stable stress and property after drying.
