Embodiment 2

[0027] In embodiment 2 of the present invention, a kind of method utilizing the puffed animal feed that corn is made, it specifically comprises the following steps:

[0028] S1, drying in the air, drying the corn bracts in the air;

[0029] S2, threshing, using a threshing machine to thresh the dried corn bracts, so as to obtain dry corn kernels;

[0030] S3, pulverize, pulverize the large-grained corn kernels into small particles of 8-10 mesh by the pulverizer, and move to the storage warehouse for storage. When storing, the moisture content of the corn kernels is regularly sampled, and the moisture content of the corn kernels is maintained at 16%, if the moisture content is higher than this value, the stored corn kernels are taken out and dried;

[0031] S4, puffing pretreatment, take the dry corn kernels and the biological puffing agent according to the ratio of 50:1 by weight, put them in the mixer and stir them evenly for 2 hours, and then let them stand for 5 hours at a...

Abstract

The invention discloses a method for preparing extruded animal feed from corn. The method specifically comprises steps as follows: airing: corn is aired and dried; threshing: the aired corn is threshed through a thresher, and dried corn granules are obtained; crushing: large corn granules are crushed into small granules of 8-10 meshes by a crusher, and the granules are transferred to a storage house for storage, timed sampling is performed on water content of the corn granules during storage, the water content of the corn granules is maintained at 14%-18%, and if the water content is higher than the value, the stored corn granules are taken out and aired. A biological extruding agent is adopted, acetic acid in white vinegar or fruit vinegar and calcium carbonate ingredients in animal bonemeal are used to produce carbon dioxide, at the moment, soybean meal is matched for coating the corn granules, so that carbon dioxide gradually permeates into the dried corn granules, the extruding efficiency is improved in the later extrusion process, meanwhile, no heavy metal addition ingredients are used in the whole process, and the whole process is safer.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for puffing animal feed made from corn. Background technique [0002] Extruded pellet feed is a new technology for feed processing. The expansion of feed in the extrusion cavity is actually a high-temperature instantaneous process, that is, the feed is under high temperature (110-200°C), high pressure (25-100 kg / cm2) and high shear force. , high moisture (10% to 20% or even 30%) environment, through continuous mixing, tempering, heating, pressurization, aging, extrusion die hole and sudden pressure drop to form bulky and porous pellet feed. [0003] For traditional corn processing, due to the high price of common metal-free puffing agents, and low-priced puffing agents mostly contain heavy metals, it is unhealthy as an animal feed additive. Contents of the invention [0004] In order to overcome the disadvantages of the above-mentioned situation, the present invention aims to prov...
