Biomass fuel such as wood pellet, briquette, charcoal made by sawdust is popular in the world which is environment friendly. It is green and renewable fuel which is good choice to replace the fossil fuel such as coal, diesel, etc.
In order to produce good quality biomass fuel, it is necessary to reduce the moisture content of wet sawdust to be about 15%-18% as need.
Then,what kind of dryer machine is suitable for drying sawdust massively ?
Obviously, it is not practical to dry the massive quantity of sawdust by sunshine. It not only will need large area, but also it is significantly influenced by the weather. What is more, its drying efficiency is rather low.
In the market, widely used Sawdust drying machine mainly has two types. One is rotary sawdust dryer, the other is airflow sawdust dryer. Rotary sawdust dryer is for the big processing capacity, and the airflow sawdust dryer is for small processing capacity.
Rotary sawdust dryer is also known as hot air type sawdust drying machine, which is specially designed for drying the wood chips, sawdust and wood pellets, wood shavings, etc. Rotary sawdust dryer is developed and optimized from the traditional rotary drum dryer machine.
Combining the past years successful experience, Sunco Machinery invented one advanced rotary sawdust dryer which is with seven inner chambers. Such new design significantly increased the contact area between the sawdust and hot air, reduce the sawdust layer thickness inside the drying machine. In the drying process, the sawdust is evenly dispersed inside the dryer drum, and to be heated and dried by hot air sufficiently, and finally the moisture content of sawdust is reduced to be about 15-18% or as need.
01. High drying intensity: since the material is highly dispersed in the hot air stream. The entire surface area of the particles is entire effective area of the particles for drying.
02. Continuous and quick drying process, and the drying time is about 15-20 minutes inside the sawdust drying machine.
03. Simple and compact structure, small floor area needed, convenient installation and maintenance.
04. Large drying capacity, high heat efficiency can be more than 70% when it is free water.
05. Easy operation, less operation and maintenance cost needed.
