  The brewer's grains are the dissolved residues and fine particles remaining after the solid grain is removed by coarse filtration after the alcohol or alcoholic beverage is distilled from the grain.

  The dry matter content of the slag waste liquid is 5-8%, and the total amount of residual organic matter in the 1 ton alcohol distillation waste liquid is more than 500kg, which causes a large amount of waste every year, and the waste liquid for producing alcohol discharge is very serious to the environment. In recent years, many breweries have begun deep processing of beer by-products. The distiller's grains are rich in nutrients and contain a variety of organic compounds, B vitamins and cellulose. It is a good edible mushroom cultivation material, as long as it is added in the distiller's grains. It can be suitable for the growth of a variety of edible fungi, which can reduce the production cost of edible fungi and solve environmental pollution problems. In rural areas, distiller's grains are now widely used as feed to feed livestock. A large amount of protein is not converted, and it is difficult to be absorbed and utilized, resulting in great waste. The most thorough and most successful treatment of waste distiller's grains is to make the distiller's grains dehydrated into compound feed, increase the potency, and make it better to digest and absorb the economical and effective methods. According to the different feeding standards of livestock and poultry, add trace elements and other additives into different compound feeds, not only can the factory turn waste into treasure, increase economic benefits, but also have important significance for controlling environmental pollution, alleviating feed shortage, saving energy and reducing emissions, and developing aquaculture.

  The brewer's grain dryer is mainly composed of a heat source, a loading machine, a drying drum, a transmission device, a cutting machine, an induced draft fan and a power distribution cabinet. The wet beer slag is sent to the drying drum, and a plurality of stencils arranged in a spiral shape are arranged in the cylinder body, and the shovel is continuously lifted by the rotation of the cylinder body, and the hitting device of the cylinder wall prevents the material bonding cylinder wall and copy board, the raised material is in full contact with the hot air flow introduced by the air intake system, which accelerates the drying heat transfer, mass transfer, evaporation of water, completes drying, and is discharged from the discharge port. The distiller's grain dryer can quickly dehydrate and dry the wet distiller's grains with a moisture content of about 65% to a dry product with a moisture content of about 10%. It is used to make high-protein feed, and realizes the mechanization and industrialization of the distiller's grains drying treatment. The equipment has high mechanization degree, large production capacity, continuous operation, convenient operation, less failure, low maintenance cost and low power consumption.
