Brewer's spent grain (BSG) or vinasse is the by product from brewery process. It contents a large amounts of nutrients. After being processed, the dried vinasse/distiller's grains are good materials for animal feed.
Our spent grain drying system is as followed: If the moisture of the wet spent grain is higher than 75%-80%, which needs the screw dehydrator to reduce the moisture to 62-65%, to reduce the burder of the dryer, then goes into the drying process, the final moisture of the spent grain can reach 12-15%;
Besides, We can offer the packing machine after the drying and crushing. We have the packing machine for 25kg/bag,50kg/bag, which can adjust according to customers' needs. We can also offer the full pellet plant, by adding some auxiliary materials, makes it into high-quality animal feed pellet.
System
Brewer's spent grains dryer mainly consists of heat source, feeding machines, feeder, rotary drum, discharging machine, draft fan, discharge and power distribution cabinet.
The brewery spent grain drying plant process as following: wet BSG-stirring to uniform--preliminary dehydration--drying--crushing--packing; then the final product sold into the market.
Advantage
a. Compared with the single rotary dryer, the floor space of the spent grain dryer is reduced by about 50%, and the investment reduced by about 40%.
The thermal efficiency of the dryer is as high as 70% (the thermal efficiency of the traditional single rotary dryer is only 35%)
b. A special breaking and lifting device was installed inner the dryer, which can effectively prevent the material from sticking to the wall and scorching;
