Method for producing feed from amino acid fermentation mother liquor and corn sugar residues

Abstract

The invention relates to the field of feed, in particular to a method for producing feed from amino acid fermentation mother liquor and corn sugar residues. The method comprises the following steps: mixing amino acid fermentation mother liquor with corn sugar residues, drying and granulating; wherein the dry matter content of the amino acid mother liquor is 40-55wt%; the corn candy pomace is wet candy pomace or dry candy pomace, and the dry matter content of the wet candy pomace is 35-50wt%; the water content of the dry candy pomace is 4-15 wt%; the mixing ratio of the amino acid fermentation mother liquor to the wet candy pomace to the dry candy pomace is (0.8-1.2): 1 and (1.5-2.5): 1 respectively. According to the method, cheap high-energy high-protein feed can be provided for feed enterprises and breeding enterprises, considerable economic benefits can be brought to amino acid fermentation enterprises, meanwhile, incineration pollution can be reduced, and the risks of oxidative deterioration, even combustion fire disasters and the like during drying and storage of the corn sugar residues are reduced to a certain extent.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for producing feed by using amino acid fermented yeast liquid and corn sugar dregs. 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 is also gradually reduced with the improvement of strains and the optimization of fermentation process, which makes it possible to bring more profits to breeding enterprises by supplementing crystalline amino to replace part of protein feed in livestock and poultry farming. Fermented amino acids are widely used in feeds using low-protein diet technology. In addition to reducing feed costs, they can also reduce diarrhea rates without affecting the growth performance of livestock and poultry. At the same time, they can red...

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
