Embodiment 1

[0028] A processing method of corn flour, specifically comprising the following steps:

[0029] The first step is to obtain corn processing raw materials: first remove the impurities from the corn raw materials, and then remove the stones and iron slag in the corn raw materials to obtain the corn processing raw materials. The corn raw material is lifted to the storage bin of the vibrating humidifier, and the corn in the storage bin is passed through the stone remover and the permanent magnetic cylinder to remove the stone and iron slag in the corn to obtain the corn processing raw material; finally, the corn processing raw material is sent into the vibrating humidifying machine. machine;

[0030] The second step is to obtain corn pre-cooking material: the corn processing raw material is fed according to the feed frequency of 18Hz under the condition of water spraying rate of 500L / h, and the water-added corn processing raw material is left to stand for 4 hours, and the water co...

Embodiment 2- Embodiment 4

[0035] The difference between embodiment 2-embodiment 4 and embodiment 1 is in table 1, as follows:

[0036] The parameter contrast table of table 1 embodiment 1-embodiment 4

[0037]

[0038] The detection results of the corn flour obtained in Examples 2-Example 4 are shown in Table 7.

Embodiment 5- Embodiment 8

[0040] The cornflour of embodiment 1-embodiment 4 is used to make creep feed respectively, and the formula of creep feed (weight ratio, and its internal unexplained composition is the composition in the prior art) is as shown in table 2 :

[0041] The formula (only corn flour is different) of the creep feed of table 2 embodiment 1-embodiment 4

[0042]

[0043]

[0044] Adopt the creep feed of embodiment 5-embodiment 8 to carry out by a definite date the feeding test of 14 days, specifically: select 90 piglets (average body weight 8.41 ± 0.35kg) that are weaned about 26-27 days of age and in good body condition, press Body weight similar principle is randomly divided into 5 test groups, 18 pigs in each test group, respectively fed with the ration (28% puffed corn, marked as control group 1) in the prior art, fed with Example 5-Example 1 8 compound feeds (marked as test group A1, B1, C1, D1), the results are as shown in table 3:

[0045] The impact of each test group on...

Abstract

The first purpose of the invention lies in providing a processing technology of corn flour. The processing technology comprises steps of processing corn materials, obtaining corn pre-cured materials and performing infrared curing (specifically, feeding the corn pre-cured materials obtained in the second step into an infrared baking machine, and heating for 18s to 30s through infrared radiation, so as to obtain cured corn materials with the surface temperature being 105 to 120 DEG C) and performing aftertreatment. The technology is beneficial to the elimination of anti-nutritional factors (such as passivation of a protease inhibitor and the inactivation of lipoxygenase) in corns through the technical scheme and an infrared baking technology, and ensures that the quality of corn flour is stabler; the technology performs high temperature sterilization during processing through an infrared baking processing technology, and reduces the risk of microbial contamination. The second purpose of the invention lies in providing a mixed feed, so as to obtain corn flour through the infrared processing technology and improve the quality of the mixed feed.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a method for processing corn flour and a compound feed using the corn flour. Background technique [0002] Corn is the main energy feed in piglet rations in my country, generally accounting for about 60% of the ration ratio. More than 70% of corn seeds are starch, which is the main source of energy for piglets. The starch molecules in corn gather together to form a dense starch granule structure, and the starch chains in the starch granules are connected to each other by hydrogen bonds, and are arranged in an orderly manner to form a crystal structure (Li Zhongrong et al., Effects of different processing corn on growth performance of weaned piglets [J], Animal Husbandry and Veterinary Medicine, 2010, 42(12): 45-47), this crystal structure is not conducive to the digestion and absorption of animals, especially the digestion of young animals is low, and the secretion of di...
