Method for producing feed through biological fermentation of distiller's grains

Abstract

The invention discloses a method for producing fee through biological fermentation of distiller's grains. The method comprises the following producing processes: 1. preparing and mixing materials, namely, dissolving an enzyme preparation and inorganic nitrogen which are externally added in water, and directly mixing uniformly with distiller's grains; 2. inoculating, wherein strain is mainly derived from animal probiotic microorganisms, and includes, but not limited in, brewer's yeast, candida utilis, endomycopsis fibuligera, bacillus subtilis, bacillus licheniformis, trichoderma koningii, geotrichum candidum and the like; 3. large-scale fermentation, namely, implementing single-bacterium or multi-bacteria mixed fermentation through a fermentation box; 4. drying; 5. rice husk separation, namely, beating dried product for several times, oscillating and filtering through a 40-60-mesh sieve to remove most rice husks; and 6. grinding and packaging. The feed disclosed by the invention is rich in mycoprotein, vitamins and bioactive substances, crude protein content is no less than 25%, and amino acid composition is rich and complete; furthermore, the product is abundant in probiotics and free from foreign sell of fresh distiller's grains, and is relatively high in feeding value. The method disclosed by the invention is short in fermentation cycle, high in automation degree and production efficiency and low in production cost, and provides a good industrial way for comprehensive treatment of distiller's grains on a large scale.

Description

technical field [0001] The invention relates to the technical field, specifically a method for producing feed by biological fermentation of distiller's grains. Background technique [0002] With the development of the liquor industry, the utilization of distiller's grains, a by-product of liquor production, has become the focus of the industry. Practice has proved that the degree of comprehensive utilization of distiller's grains directly affects the development of enterprises. If it is not handled properly, the pressure on the environment will be huge; and the level of distiller's grains processed feed is related to the implementation of national feed policies. [0003] For a long time, distiller's grains have been directly used as rural feed, which has played an important role in promoting the development of rural breeding industry and the virtuous circle of the biological chain. However, the nutritional structure of fresh distiller's grains can no longer meet the require...

Problems solved by technology

During process control, ventilation and temperature control are difficult to achieve

[0006] The second is that the degree of automation is low, requiring more labor, and the labor intensity is high, and it faces major problems in industrialization.

[0007] The third is that the acidity of distiller's grains is low, and the existing methods often require acidity adjustment, which is inconvenient to operate and increases the processing cost
