Problems solved by technology

At present, solid-liquid separation, concentration and drying processes are often used to convert alcohol waste liquid into feed, which produces a large amount of sewage and consumes a lot of energy. Utilizing alcohol waste liquid to develop energy-saving feed and full utilization has become the most valuable utilization method for the development of the alcohol industry. Therefore it is necessary to invent a method for preparing feed protein by utilizing alcohol waste liquid and crop stalks

Embodiment 1

[0026] A method for preparing feed protein by using alcohol waste liquid and crop stalks, the specific preparation steps are as follows:

[0027] (1) Basic treatment of feed raw materials: First, crush the straw: select straw without mildew, remove impurities such as soil, and crush through a 60-mesh sieve.

[0028] (2) Solid-liquid separation: The alcohol waste liquid is separated from the solid-liquid by natural sedimentation, and the supernatant and fermented distiller's grains are obtained.

[0029] (3) Processing of straw:

[0030] Ammonification of straw: add 3% ammonia water of straw, add the supernatant of alcohol waste liquid, adjust the water content to 50-65%, mix well, and put it in a closed environment for ammoniation for 2 days.

[0031] Straw enzymatic hydrolysis: adjust the pH of the ammonified straw to 4.0, add cellulase, xylanase, and pectinase, the amount of enzyme added is %, 4%, and 2%, mix well, enzymatic hydrolysis for 10 hours, and enzymatic hydrolysis...

Abstract

The invention discloses a method for preparing a feed protein from alcohol waste liquid and crop straws, aiming at phenomena that the utilization rate of crops straw feed is not high and alcohol waste liquid pollution is caused, so as to meet straw comprehensive utilization requirements, requirements of animal husbandry feed proteins and objective requirements of alcohol waste liquid harmless treatment and utilization. The method disclosed by the invention mainly comprises the following three steps: ammonifying, carrying out compound enzymatic hydrolysis and carrying out multi-strain three-step solid-state fermentation. The method disclosed by the invention has the advantages of promoting growth and development, improving the feed utilization rate, improving the intestinal micro-ecology, preventing diseases and the like; recycling high-value utilization of the crops straws and harmless treatment and resource utilization of the alcohol waste liquid are realized; healthy, green and scientific development of a feed processing industry is facilitated, and the method has a wide application prospect.

Description

technical field [0001] The invention relates to a method for preparing feed protein by using alcohol waste liquid and crop stalks, and belongs to the field of feed technology processing. Background technique [0002] At present, with the improvement of people's living standards and the emphasis on the quality of life, the demand for meat, eggs, milk, and aquatic products is increasing. The production of food and feed is facing severe challenges, and feed protein resources will become increasingly scarce. [0003] Therefore, it is imminent to improve the conversion efficiency of grain to animal husbandry products and the utilization rate of feed, expand feed resources, and develop unconventional feed. Protein raw materials are the basis for the development of feed industry. The shortage and high price of protein raw materials in my country have become constraints to the development of animal husbandry. One of the bottlenecks, the strategy adopted for this purpose is to improve...
