specific Embodiment approach 1
[0017] The method for preparing bio-fermented feed by the by-product of producing cornstarch by wet method comprises the following steps:
[0018] Step 1: Weigh the three raw materials of sprayed corn husk, corn germ meal and corn steep liquor at a mass ratio of 2.4:1.2:1, add 30% sodium hydroxide solution, adjust the pH value of the raw materials to 4.3, and obtain mixture A ;
[0019] Step 2: After adding water to adjust the water content of mixture A to 45%, add 1% of the total amount of the mixture of Bacillus subtilis and Saccharomyces cerevisiae, and mix thoroughly to obtain mixture B;
[0020] Step 3: Put the mixture B in a closed environment at 30° C., and carry out anaerobic fermentation for 96 hours to obtain a biologically fermented feed.
Embodiment 1
[0022] This embodiment discloses the method that utilizes the by-product of wet method to produce cornstarch to prepare biofermentation feed, comprises the following steps:
[0023] Take the preparation of bio-fermented feed with a total amount of about 1 ton as an example:
[0024] Weigh 362.6kg of sprayed corn husks, 181.3kg of corn germ meal, and 151.1kg of corn steep liquor; add 30% sodium hydroxide to adjust the pH value of the material to 4.5 to obtain mixture A, and add water to adjust the moisture content of mixture A to 45 %, finally add a mixture of Bacillus subtilis, Saccharomyces cerevisiae, and lactic acid bacteria that account for 1% of the total amount of materials, mix well and pack them into one-way air intake valve pockets, and place them in an environment of 36°C for no less than 72 hours anaerobic fermentation to obtain biologically fermented feed.

Abstract
The invention relates to a method for preparing a biological fermentation feed from by-products generated during production of corn starch by a wet method, and belongs to the field of feed processing.By-products of wet corn husks, corn germ meal and corn steep liquid, in the production process of corn starch by the wet method are used as raw materials in the proportion of the gunite corn husks tothe corn germ meal to the corn steep liquid being 2.4 to 1.2 to 1. The method comprises the following steps of adding a 30% sodium hydroxide solution, regulating the pH value to 4.3-4.7, adding waterto regulate the moisture content of a mixture to 45%, adding species which are 1% of total production quantity, performing thorough mixing, and then performing anaerobic fermentation at 30-40 DEG C for 72 hours or above so as to prepare qualified biology feed products. The biological fermentation feed product prepared by the method disclosed by the invention contains a large quantity of probioticcolonies, an immune enhancer, a growth factor, amino acids and the like. After the biological fermentation feed is added to animal feeds, flora of animal intestines can be regulated to be balanced, and the immunity and the irritability are improved.
Description
technical field [0001] The invention belongs to the field of feed preparation, and in particular relates to a method for preparing biologically fermented feed by using the by-products of cornstarch produced by a wet method. Background technique [0002] In the process of wet production of corn starch, the soaked corn kernels are separated, screened, and dehydrated to form wet fibers, which are sprayed and then dried to form sprayed corn husk feed; the separated germs are pressed and leached to form germ meal, sprayed After drying, corn germ meal feed is formed; after impregnation, sulfurous acid forms dilute corn steep liquor, and after evaporation, it is concentrated to form corn steep liquor. [0003] The disadvantages of the by-products produced in the above-mentioned wet process of producing corn starch are: single nutritional components, poor palatability, and low digestibility after eating by animals. Although the sprayed corn husk feed and corn germ meal feed have be...
