Spent Grain Dryer
Brewer’s spent grain (BSG) is the by-product of the beer production process. It contents a large amount of nutrients such as undecomposed crude protein, crude fiber, crude fat and other nutrients. The dried distiller’s grains are good raw materials for the animal feed production. Through pre-dehydration, the distiller’s grain dryer can dry wet waste grain from about 85% moisture content to finished products with a moisture content of about 10%.

Application of Spent Grain dryer
Our spent grain dryer can be used for drying vinasse, brewery dregs, brewery waste, beer distillers’ grains, etc. It is also applicable for wood chips, sawdust, corn straw, soybean straw, cotton stalk, wheat straw, sorghum stalk, mulberry leaves and other biomass materials.
Advantage of Spent Grain Dryer
1.The main components of our rotary dryer are made of high-end materials, with reliable quality, and the service life is 3-5 times than that of ordinary dryers.
2. Equipped with a combined lifting device, the thermal efficiency is high, and the drying effect is good.
3. The dust removal device can completely avoid dust pollution during operation and meet the requirements of environmentally friendly production.
4. The flow rate of distiller’s grains is controlled by frequency conversion, which can easily control the final moisture according to the needs of users.
5. Equipped with a new type of energy-saving hot-blast stove, high efficiency and energy saving, heat controllable, reducing operating costs.
Waste Grain Dryer Process
The spent grain dryer mainly consists of heat source, feeder, dryer host, induced draft fan, discharge device, and power distribution cabinet. After dehydration, the wet distiller’s grains enter the dryer and are evenly dispersed in the dryer under the rotation of the evenly distributed boards in the drum, fully in contact with hot air. During the drying process, under the action of the inclined lifting plate and hot air, the spent grain is discharged to the unloader at the other end of the dryer.
