Alcohol, starch sugar, monosodium glutamate, citric acid, and other industries in the food industry mainly use grain as raw materials, but the utilization rate of raw materials is low, and at least 30-40% of the raw materials become wastewater. The dry matter content in the wine residue waste liquid reaches 5-8%, and the total amount of residual organic matter in 1 ton of alcohol distillation waste liquid is more than 500kg, which not only causes a lot of waste but also causes serious environmental pollution.

Many breweries have begun to deep-process 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 raw material for edible fungi cultivation. It can be suitable for the growth of a variety of edible fungi, which can not only reduce the production cost of edible fungi but also solve the problem of environmental pollution.

In rural areas, distiller’s grains are generally used directly as feed to feed livestock, and a large amount of protein cannot be converted, and it is difficult to be absorbed and utilized, causing a lot of waste. The most thorough and successful treatment of waste distiller's grains is to dehydrate the distiller's grains into the compound feed to make it better digested and absorbed. According to different feeding standards of livestock and poultry, adding trace elements and other additives can make different compound feeds. Not only can the factory turn waste into treasure and increase economic benefits, but it is also of great significance to the treatment of environmental pollution, alleviating the shortage of compound feed, energy-saving and emission reduction, and the development of aquaculture.

beer grain dryer

Dingli distiller’s lees dryer can quickly dehydrate and dry the wet distiller’s lees 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, automation, and industrialization of the drying of distiller’s grains. 

Dingli distiller’s lees drying has a high degree of mechanization, large production capacity, continuous operation, excellent structure, stable operation of materials through the resistance of the cylinder, convenient operation, fewer failures, low maintenance costs, low power consumption, and good product drying uniformity.
