Sawdust is a waste product generated during wood processing. Sawdust drying is a prerequisite for many subsequent processing steps, such as charcoal production, biomass pellet production, etc. By drying, the moisture content of sawdust can be reduced, thereby improving the efficiency and product quality of subsequent processing, while reducing transportation costs and storage risks.

  Sawdust dryer is an equipment used to dry wet sawdust to the required humidity. The most common type is a rotary dryer, which consists of a heating system, a feeding and discharging device, a drying cylinder, etc.

  Working principle of sawdust dryer

  The wet sawdust is transported into the drying drum through the feeding device. As the drum rotates, the sawdust is constantly thrown up and down, fully in contact with the hot air, and the moisture evaporates. The dried sawdust is discharged through the discharge port, and the exhaust gas is purified by dust removal devices such as cyclone dust collectors and then discharged. The selection of heating devices for sawdust dryers is diverse, and the heat source can be various cheap fuels such as biomass, natural gas, fuel oil, propane, etc.

  Features and advantages of sawdust dryer

  1. High efficiency and energy saving: adopts a circulating hot air system, with high thermal efficiency and low energy consumption.

  2. Simple structure: easy operation and maintenance, suitable for large-scale production.

  3. Fast drying speed: sawdust can reach the required humidity in a short time.

  4. Wide range of applications: can be used to dry a variety of biomass materials such as sawdust, straw, rice husks, etc.

  Industry applications

  1. Biomass fuel production: such as the production of sawdust pellets, sawdust briquette, and charcoal.

  2. Agricultural engineering: used to dry agricultural waste such as straw and rice husks.

  3. Wood processing industry: used to process by-products such as sawdust and shavings.
