The news will explore ways to increase the efficiency of soybean slag rotary dryers used in wood pellet production. It will focus on practical tips and strategies that can help producers maximize their output and minimize energy consumption.

1.Pretreatment of wet soybean slag:
The water content of wet soybean slag is usually very high, usually about 80%‌.
Before entering the dryer, the soybean slag will first go through the dehydrator to remove most of the free water, so that the moisture content is reduced to 55-60%‌.
‌2. Enter the dryer:
The dehydrated wet soybean slag is fed into the soybean slag rotary dryer.
The dryer is mainly composed of heating source, feed machine, rotary drum, discharge machine, induced draft fan, discharge and distribution cabinet‌.
‌3. Drying process:
In the dryer, the wet bean slag is uniformly dispersed and fully in contact with the hot air under the action of the inclined sheet and the hot medium, which speeds up the.
4. Heat and mass transfer process.
The soybean slag is turned by the uniformly distributed sheet in the drum to form a uniform material curtain and realize the heat exchange with the hot air.
High degree of mechanization, large production capacity, continuous operation, and good uniformity of product drying.
‌5. Dispersion and expulsion:
Soybean slag drying production line adopts a special dispersion device to ensure the drying effect of the dryer, so that the soybean slag can be fully dispersed in the drying process, improve the drying efficiency.
The dried bean slag is discharged through the star-shaped discharge valve.
‌6. Follow-up Procedure:
The dried soybean slag can be crushed, mixed, granulated, packed and other subsequent processing according to needs to produce soybean slag pellet feed products.
The whole production process has realized a high degree of mechanization and automation, and the operation is convenient, the fault is less, the maintenance cost is low, effectively improve the production efficiency and economic benefits.
