Distillers grains are a cereal byproduct of the distillation process. Brewer's spent grain usually refers to barley produced as a byproduct of brewing, while distillers grains are a mix of corn, rice, and other grains.

The 60-65% liquor lees screw conveyor is sent to the mixing drum dryer to achieve downstream drying. The materials are continuously picked up and scattered under the copy board and move forward in a spiral manner. The built-in multi-layer copy board structure fully mixes the materials. Disperse and throw, the material and the hot air fully exchange heat, the moisture quickly evaporates and vaporizes, the material that achieves the drying effect quickly travels out of the drum under the action of the hot air, and the wet material that does not achieve the drying effect cannot travel quickly due to its own weight. Drying, which achieves the drying effect, completes the drying process and is discharged by the screw conveyor. A shock cleaning device is installed inside the drum to prevent the material from adhering to the wall of the drum. The gas flow is: the air is pressurized by the hot blast stove blower into the hot blast stove for combustion and heating, and the temperature reaches 600-950 ℃. It is sucked into the dryer by the induced draft fan after the dryer to dry the material and evaporate the moisture. After three layers of heat exchange, the wind temperature The temperature is lowered to 55-60℃ and discharged out of the dryer. The dust-containing moisture is collected by the cyclone dust collector, and the wet dust collector is purified and discharged to the standard.
