Problems solved by technology

However, it controls the particle size through the aperture of the sieve, and the particle size of the material is smaller than the aperture of the sieve. When rotating at high speed during processing, it is easy to cause a large part of it to be far smaller than the aperture of the sieve, resulting in uneven particle size of the material.
We used to adjust the particle size of the material by reducing the speed, but after granulation, the particle size is coarse and fine, and the uniformity is poor, and there are disadvantages such as low energy utilization rate, high power consumption, heat generation, dust, and noise.

Abstract

The invention discloses a granularity-adjustable laying hen feed and a preparation method thereof and belongs to the technical field of feed processing. The preparation method of the laying hen feed mainly comprises the following steps: taking corns as the main raw materials of the laying hen feed; grinding the corns by a double-roller grinder; screening the grinded corns by a vibration sieve; further grinding the screen residues by a hammer grinder; uniformly mixing the further grinded screen residues with the screened grinded corns; grinding soybean meal, DDGS, corn bran, double-low vegetable meal, monosodium glutamate protein and palm meal by a hammer grinder; then preparing the laying hen feed according to the conventional method. Preferably, the ratio of the digestible amino acids in the laying hen feed is DLys: (DM plus C): DThr: DVal: DArg equals 100: 84: 67: 87: 94; moreover, the yeast powder fermented from the preserved bacteria Rhodotorula benthica WYN1 whose preservation code is CCTC No: M 2014592 is specially added in the laying hen feed; thus, the grinding time is shortened, the dust is reduced, the production efficiency is improved, the breeding effect is raised and the egg quality is improved.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a method for preparing laying hen feed by using a roller pulverizer in the preparation of laying hen feed and improving the processing technology, and relates to the laying hen feed prepared by the preparation method. Background technique [0002] With the development of animal husbandry, the shortage of feed raw materials and the increasingly serious problems of environmental pollution, the research on feed in this field has also been paid more and more attention, and the research on laying hen feed is also an important part of it. [0003] The Chinese invention of application publication number CN104012810A "A Feed for Layers Containing Muyu Stone Powder" discloses a feed for laying hens containing Muyu stone powder. The laying hen feed containing wood fish stone powder is made of the following raw materials in parts by weight: 60-70 parts of cornmeal, 10-20...
