A method for producing feed by utilizing amino acid yeast liquid and corn sugar residue

Abstract

The invention relates to the field of feed, and specifically relates to a method for producing feed by utilizing amino acid fermentation yeast liquid and corn sugar residue. The method includes: mixing the amino acid fermentation yeast liquid and corn sugar residue, drying and granulating; wherein the dry matter content of the amino acid mother liquor is 40-55wt%; the corn sugar residue is wet sugar residue or dry sugar residue, and the wet sugar residue is wet. The dry matter content of sugar residue is 35-50wt%; the moisture content of dry sugar residue is 4-15wt%; the mixing ratio of amino acid fermentation yeast liquid to wet sugar residue and dry sugar residue are 0.8-1.2:1 and 1.5-2.5 respectively. :1. The method of the present invention can not only provide cheap high-energy and high-protein feed for feed enterprises and breeding enterprises, but also bring considerable economic benefits to amino acid fermentation enterprises. At the same time, it can also reduce incineration pollution and reduce corn sugar to a certain extent. There are risks such as oxidative deterioration during slag drying and storage and even combustion and fire.

Description

Technical field [0001] The invention relates to the field of feed, and specifically relates to a method for producing feed by utilizing amino acid fermentation yeast liquid and corn sugar residue. Background technique [0002] With the development of genetic engineering technology, the production technology of most amino acids has transitioned from traditional methods such as chemical synthesis and protein hydrolysis to microbial fermentation. The production cost of amino acids has also been gradually reduced with the improvement of bacterial strains and the optimization of fermentation processes. This allows the supplementation of crystalline amino acids to replace part of the protein feed in livestock and poultry breeding, which can bring more profits to breeding companies. Fermented amino acids are commonly used in feeds that apply low-protein diet technology. In addition to reducing feed costs, they can also reduce diarrhea rates without affecting the growth performance ...

AI Technical Summary

Problems solved by technology

Although this method solves the difficulty of downstream processing of sugar tailings and tryptophan mother liquor in the production process of tryptophan, the corn bran used in it is a relatively high-value feed raw material, and it is combined with corn steep liquor, tryptophan mother liquor, etc. The blending of relatively low-value ingredients reduces the overall value of the product

In addition, this method requires many kinds of raw materials, and steps such as fermentation are also required, so problems such as long production process and high production cost are caused, and it is not suitable for actual industrial production.

[0008] And CN 102578385A mentions a kind of preparation method of low-content L-threonine feed, the entrapment liquid and mother liquor produced in the high-content L-threonine feed preparation process are used as raw materials, supplemented with corn fiber, zein and light Calcium three kinds of feed additives are prepared into high-quality low-content L-threonine feed, which solves the problem of environmental pollution from retentate and mother liquor, but the products produced by this method are prone to moisture absorption under high humidity conditions in summer Agglomeration phenomenon, even if sealed packaging after production, caking phenomenon cannot be avoided during feed mill application, which is why this technology is not widely used
