Embodiment 1

[0028] Include the following steps:

[0029]After the raw corn is tested and purified, it enters each corn soaking tank, and the circulating process water is poured into the corn soaking tank for pre-soaking. The process water is overflowed after being centrifuged in the last gluten concentration centrifuge in the corn protein concentration process. Process water, the temperature is 48°C, the mass ratio of process water to raw corn is 0.9:1, keep the process water level in the tank below the corn, and regularly check whether the corn in the tank is completely submerged;

[0030] Soaking time: Soak wet grain for 1 hour, soak dry grain for 2 hours, use circulating heating to keep the temperature of the soaking tank at 48°C during soaking; soak two cans of corn in the process water circulation: when one can of corn is pre-soaked, the process water in the tank Use a circulation pump to drive into the next tank. After the next tank of corn is pre-soaked with process water, the proc...

Embodiment 2

[0033] Include the following steps:

[0034] After the raw corn is tested and purified, it enters each corn soaking tank, and the circulating process water is poured into the corn soaking tank for pre-soaking. The process water is overflowed after being centrifuged in the last gluten concentration centrifuge in the corn protein concentration process. Process water, the temperature is 50°C, the mass ratio of process water to raw corn is 0.9:1, keep the process water level in the tank below the corn, and regularly check whether the corn in the tank is completely submerged;

[0035] Soaking time: Soak wet grain for 1 hour and dry grain for 2 hours. During the soaking period, use circulating heating to keep the temperature of the soaking tank at 50°C; soak two cans of corn in the process water circulation: when one can of corn is pre-soaked, the process water in the tank Use a circulation pump to drive into the next tank. After the next tank of corn is pre-soaked with process wate...

Embodiment 3

[0038] Include the following steps:

[0039] After the raw corn is tested and purified, it enters each corn soaking tank, and the circulating process water is poured into the corn soaking tank for pre-soaking. The process water is overflowed after being centrifuged in the last gluten concentration centrifuge in the corn protein concentration process. Process water, the temperature is 52°C, the mass ratio of process water to raw corn is 0.9:1, keep the process water level in the tank below the corn, and regularly check whether the corn in the tank is completely submerged;

[0040] Soaking time: Soak wet grain for 1 hour and dry grain for 2 hours. During the soaking period, use circulating heating to keep the temperature of the soaking tank at 52°C; soak two cans of corn in the process water cycle: when one can of corn is pre-soaked, the process water in the tank Use a circulation pump to drive into the next tank. After the next tank of corn is pre-soaked with process water, the...

Abstract

The invention relates to a detoxification method of vomitoxin in a process of corn deep processing, and belongs to the field of corn deep processing. Raw material corn is detected, purified, and poured into a plurality of corn soaking cans; circulating process water is injected into the corn soaking cans; presoaking is conducted at a temperature of 48-52 DEG C, wherein a mass ratio of the process water to the raw material corn is 0.9:1; during soaking, circulating heating is utilized to keep the soaking cans at a temperature of 48-52 DEG C; and after presoaking in the process water, the process of sulfurous acid soaking is conducted. The present invention has the advantages that a vomitoxin content of the raw material corn greatly declines; finally obtained guniting feed products have a significant detoxification effect of the vomitoxin with a detoxification rate of 50-70%; original technological processes of production are not changed; and the method needs low investment, and has fast effectiveness, and is convenient and feasible, and can greatly raise economic benefits, and is beneficial for popularization and application in the industry of corn wet grinding and deep processing.

Description

technical field [0001] The invention belongs to the technical field of corn deep processing, in particular to a method for detoxifying corn raw material vomitoxin in the production process of corn deep processing. Background technique [0002] The current production method of corn (starch) deep processing is mainly: corn adopts wet milling process, which uses physical methods to separate the main components of corn through sulfurous acid soaking, crushing, separation, drying and other processes to obtain corresponding products . Five main components can be obtained through this process, namely sprayed corn bran, corn gluten meal, corn germ meal, corn crude oil and starch. [0003] Mycotoxins inevitably exist in corn raw materials. Coupled with the abnormal global weather in recent years, the problem of mycotoxin pollution in a large number of corn raw materials has become increasingly serious, which directly leads to excessive toxins in various corn deep-processing products...
