Among the large number of by-products in the brewery, the wet brewer’s grains are the largest, but the wet brewer’s grains are easy to deteriorate, so it is easy to pollute the environment during transportation and storage. In recent years, many breweries have begun to deep-process beer by-products. It can reduce environmental pollution and increase economic benefits. The brewer’s grain dryer can quickly dehydrate and dry the wet brewer’s grains with a moisture content of about 85% to dry products with a moisture content of about 10%. A number of domestic beer companies and feed processing companies have been put into use, and have created considerable economic benefits.
Structure and process of distiller’s grains dryer
The brewer’s grains dryer is mainly composed of a heat supply source, a feeder, a feeder, a rotary drum, a discharge machine, an induced draft fan, a discharger and a power distribution cabinet; after the dehydrated wet brewer’s grains enter the dryer, Under the turning of the evenly distributed copying plate in the drum, it is evenly dispersed in the dryer and fully contacted with the hot air, which accelerates the heat and mass transfer of drying. During the drying process, under the action of the inclined copy board and the heat medium, the beer grains are discharged to the star-shaped discharge valve of the other section of the dryer to discharge the dried products.
The performance characteristics of the distiller’s grains dryer
- The uniformity of product drying is good.
- The structure is excellent, simple, the material runs smoothly through the resistance of the cylinder, and the operation is convenient.
- Fewer failures, low maintenance costs, and low power consumption.
- High degree of drying mechanization, large production capacity, and continuous operation.
