Brewer's grain is a by-product of beer production, which has the characteristics of low price, large output, rich nutrients and good fattening effect. The development of distiller's grains into unconventional feed can greatly alleviate the shortage of feed resources, reduce breeding costs, and improve economic benefits. The market prospect of granule feed made from beer grains after drying is broad. With beer residue oil as the basic raw material, protein feed can be obtained after certain procedures. It is a feed with high nutritional content. Treasure, reduce pollution.

Among the large amount of by-products in breweries, wet beer grains are the most productive, but wet distiller's grains are easy to deteriorate, so they are easy to pollute the environment during transportation and storage. In recent years, many breweries have begun to carry out deep processing of beer by-products, which can reduce Environmental pollution can also increase economic benefits. The brewer's grain dryer developed by Zhengzhou Dingli can quickly pre-dehydrate the wet brewer's grain with a moisture content of about 85%, and then dry it to a dry product with a moisture content of about 10%. At present, this set of equipment has been put into use in many domestic beer companies and feed processing companies, and has created considerable economic benefits. The brewer's grain dryer is mainly composed of a heat source, a feeder, a feeder, a rotary drum, a discharge machine, an induced draft fan, an unloader and a power distribution cabinet; after the dehydrated wet brewer's grains enter the dryer, Under the turning of the evenly distributed lifting plates in the drum, they are evenly dispersed in the dryer and fully contacted with hot air, which speeds up the heat transfer and mass transfer of drying. During the drying process, the brewer's grains are discharged to the star discharge valve at the other section of the dryer to discharge the dried product under the action of the inclined lifting plate and the heat medium.
