The sawdust dryer machine can quickly reduce granular materials with a moisture content of 45% -60% to below 10%. For the fast drying of sawdust and rice husk in the wood processing plants, the airflow dryer, and the drum dryer can be considered. These two types of drying equipment are very efficient and have been exported to many foreign countries, such as Korea, Malaysia, Nigeria, Ghana, Saudi Arabia, South Africa, Indonesia, Philippines, Chile, Canada, etc
Airflow sawdust dryer machine, also known as hot air duct dryer, is mainly composed of a series of pipes and pulse tubes. The machine should be connected with a combustion furnace (self-built or bought) and a cyclone dust collector in actual work
The airflow dryer uses the principle of hot air to dry the materials instantly, and the hot air of the combustion furnace is extracted into the pipeline through the fan, which is fully mixed with the materials inside to achieve the purpose of rapid drying
The machine has certain requirements for the size of the material to be dried. Rice husks with a length of less than 5mm and a diameter of less than 3mm, wood shavings, sawdust, wood chips, etc. can be dried. The diameter of the sawdust dryer pipe and the size of the fan determine the size of its processing capacity
The sawdust dryer has a cylindrical structure. The main parts include a combustion furnace (self-built or purchased), a feed port, a rotating drum, a built-in scraper, a cooling drum, a reduction motor, a fan, and a dust collector. The rotating drum of the machine is placed on the roller.
The roller is driven by the motor and deceleration drive to rotate the rotating drum at a low speed. When working, the fan will draw the hot air from the furnace into the drum. The material will be fully mixed with the hot air when turning in the drum to achieve the drying effect
(1) The material enters the inner layer of the rotary drum from the feeding device to realize downstream drying. The material is continuously copied down the inner plate of the inner layer, and the scattering is spirally moving to realize heat exchange
(2)Then the material is moved to the other end of the inner layer to enter the middle layer. And the countercurrent drying is carried out, the materials are repeatedly carried forward in the middle layer, and the materials are continuously repeated in the middle layer , so that the material absorbs the heat generated by the inner drum in the middle layer and absorbs the heat of the middle drum. Meanwhile, the drying time is prolonged, and the material achieves the best drying state
(3) The material goes to the other end of the middle layer and falls into the outer layer. The material travels in the outer cylinder in a rectangular multi-loop manner.The material that reaches the drying effect moves quickly out of the roller under the action of hot air. Wet materials that do not reach the drying effect cannot travel fast because of their weight
