Product Description

沙子烘干机2.png

The sawdust dryer is designed for the characteristics of higher initial moisture of sawdust than other materials, lower specific gravity than other materials, and large changes in fluidity during the drying process. It has the advantages of compact structure and less floor space. It is widely used for drying work in industries such as straw briquetting fuel, charcoal machinery, wood pellet fuel, sawdust briquetting, and agricultural and animal husbandry engineering.

Product Advantage

Product advantages

1. Compared with other types of dryers, sawdust dryers have higher efficiency and shorter drying time.

2. The air dryer has a simple structure, a small area, and is easy to construct and maintain.

3. Large processing capacity and high thermal efficiency. When drying unbound water, the thermal efficiency can reach 60%.

4. The drying strength is large. Because the material is highly dispersed in the airflow, the entire surface area of the particles is extremely dry and effective.

Working Principle

Structure principle

Sawdust dryer: including hot blast stove, feed inlet, rotating drum, filter drum, material conveying pipe, cooling drum and discharge port. The rotating drum is located on the driving roller, which is driven by the motor and deceleration transmission to drive the rotating drum to rotate at low speed. There is a feed inlet between the heating furnace and the rotating drum. The rotating drum is equipped with stir-frying blades. A baffle is provided at the connection between the rotating drum and the filter drum 4. The baffle has a small hole. The cylinder is connected, the other end is connected with the material conveying pipe, the filter cylinder is provided with a stopper, the bottom of the filter cylinder is provided with a slag discharge hole, one end of the cooling cylinder is connected with the material conveying pipe through a blower, and the other end is connected with the discharge port.

Due to the above structure, the sawdust can be fully dried in the rotating drum, and the sawdust is fully dispersed again before entering the material conveying pipe, so that the water evaporates quickly, and the stopper can block the impurities in the sawdust to ensure that the sawdust enters the material conveying pipe. the quality of. The sawdust enters the sawdust dryer by the blowing pipe and the rotating cylinder. The material is boiling and fluidized in the cylinder, and the hot air and the material are fully contacted to complete the drying.

Drying system

Sawdust dryer refers to the powdery granular wet sawdust, which is continuously fed into the drying tube by a screw conveyor. In the transportation and dispersion of high-speed hot air flow, the process of evaporating the moisture in the wet material to obtain a powdery or granular dry product. It is mainly composed of air heater, feeder, air drying tube, cyclone separator, fan, etc.
