Device and method for fermenting distillers' grains into livestock and poultry feed

Abstract

The invention discloses a device and method for fermenting distillers' grains into livestock and poultry feed. The device comprises a mixing bin, a drying bin and a fermentation sealing bin. The device is reasonable in structural design, has secondary drying and screening functions, ensures full fermentation and drying of distillers' grains feed, screens granules uniformly, facilitates eating by livestock and poultry, facilitating long-term transportation or preservation and avoids mildew due to dampness; meanwhile, a distillers' grains fermented material is used as a raw material, waste is utilized fully, the device is green and environmentally friendly, the content of cellulose in the distillers' grains is fully reduced, the content of protein is improved, various nutrient ingredients such as amino acids and vitamins are reserved, the digestive absorption rate of materials is greatly improved, side effects such as an anti-nutritional effect are reduced, rich protein and microelementsare provided, the production cost of the distillers' grains feed can be reduced, the process is simple, and the distillers' grains are good in drying and screening effects, easy to preserve and transport and high in utilization rate of nutrient substances.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding, in particular to a device and method for fermenting distiller's grains into livestock and poultry feed. Background technique [0002] As a by-product of liquor, distiller's grains are good feed with high nutritional content, which is beneficial to the growth of livestock and poultry. It has been determined that distiller's grains are rich in protein, and eighteen kinds of amino acids can be detected from distiller's grains. Distiller's grains are also rich in inorganic elements such as phosphorus and potassium, and vitamins. In addition, there may also be trace beneficial components such as ribonucleic acid and purine produced by microorganisms, all of which are incomparable to grains, which is an important feature of distiller's grain feed nutrients that are different from grains. And at present, the livestock and poultry breeding industry is mainly facing the following ...

Problems solved by technology

[0003] At present, distiller's grains are generally used as feed or fed directly with other feed additives, or solid distiller's grains are separated from rice husks and dried or dried, and then combined with other raw materials to produce different types of feed, or distiller's grains powder is used with other raw materials Compound production of feed, but these feeds are not fully fermented and dried, the particles are uneven, and some large distiller's grain particles are still wet, resulting in low utilization of distiller's grain nutrients, which is not conducive to transportation and storage, and the existing distiller's grain feed production High cost and complicated process
