Biologically fermented feed as well as preparation method and special device thereof

Abstract

The invention relates to a biologically fermented feed as well as a preparation technology and a special device thereof. The preparation technology comprises the steps of: pre-cleaning, grinding, mixing, inoculating, packaging and fermenting raw materials, is simple and convenient to operate, and realizes the mechanical continuous production. In the formulation of the biologically fermented feed, leftovers of agricultural and sideline products, with the low price, such as apple pomace, jujube powder, peanut shells, distillers dried grains with soluble (DDGS), spray corn husks and other biological matrixes are adopted, and the biologically fermented feed is prepared by adding a premix and bacteria liquid into the leftovers, mixing and fermenting. The prepared biologically fermented feed is stable in quality, good in palatability, comprehensive in nutritive value, high in living bacterium content and easy to store and transport, can be directly fed as daily ration of livestock and poultry, and can replace 20-30% of a complete formula feed, thus saving grains in deed and reducing the breeding cost.

Description

technical field [0001] The invention relates to a feed for livestock and poultry, in particular to a biologically fermented feed and its preparation method and special equipment. Background technique [0002] At present, in the feed and breeding industry, there are large drug residues, a large potential threat to food safety, low feed profit margins, high breeding costs, large market fluctuations, prominent contradictions between humans and animals competing for food, and a large number of leftover resources of agricultural and sideline products have not been rationally allocated. Under the current situation of prominent problems such as development and utilization, the use of plant stem husks and agricultural product waste to ferment to produce food-saving and antibiotic-free green and safe biological feed is in line with the grand premise of the scientific development concept and the national industry policy. It can turn waste into treasure and reduce Reduce feed costs, in...

AI Technical Summary

Problems solved by technology

However, most of them are currently limited to single feed materials such as fermented straw, fermented soybean meal, fermented cotton meal, fermented brewer's grains, etc. Even if there are manufacturers of fermented mixed raw materials, their production process is still based on traditional family workshops. Production is mainly based on traditional production methods, and mechanized, continuous and large-scale production has not yet been formed.

Existing fermented feeds often use fresh brewer's grains or fresh soy sauce grains as raw materials, but the moisture in the final product is difficult to control, and often encounters uneven mixing, difficult fermentation in winter, low survival rate of bacteria, difficulty in controlling the degree of fermentation, and easy fermentation. Technical bottlenecks and product defects such as mildew, unstable quality, low nutritional value, poor palatability, and unsuitable storage
