Abstract

The invention relates to the technical field of disinfection methods of feeds, and particularly relates to a sterilizing process of an animal feed. The sterilizing process comprises the steps of: a, liquefying high-concentration gaseous ozone by water mist spraying to obtain high-concentration liquid ozone; b, loading a dried feed in a high-pressure sealed disinfection tank, adding the liquid ozone in the high-pressure sealed disinfection tank, uniformly stirring, simultaneously introducing the high-concentration gaseous ozone, and sterilizing by an ultraviolet lamp; c, adding quaternary ammonium salt in the disinfection tank; d, after disinfecting, introducing high-temperature steam in the disinfection tank, and stirring the feed to thoroughly remove ozone residues; and e, adding active bacteria into the disinfection tank for fermenting the animal feed. The sterilizing process is scientific, reasonable and safe, has an environment protection effect, and is strong in maneuverability, is thorough in sterilization, convenient to operate, free of toxicity, odor and irritation and strong in bacterial property as adopting a physical and chemical combined mode for sterilization; nutrient substances in the feed are protected from being damaged, nutritional ingredients of the feed increase, the feed is safe and reliable, and no economic loss is caused.

Description

A kind of sterilization process of animal feed

Technical field

The present invention relates to the sterilization method technical field of feed, be specially a kind of sterilization process of animal feed.

Background technology

Present development along with aquaculture; many feed lots and individual mostly adopt the concentrated stable breeding mode of scale, industrialization to carry out raise poultry; because make and carry out in this way raise poultry product effect height; can realize scientific nursing, also be the effective way that realizes income multiplication plan.Feed is requisite poultry food in the process of raise poultry, comprise soybean, dregs of beans, corn, fish meal, amino acid, the assorted dregs of rice, additive, whey powder, grease, meat meal tankage, cereal, the feedstuff that sugar grass etc. are tens kinds, and wherein a lot of extract from crops, and the residual quantity of present crops Pesticides is more serious, directly can make poultry tortured by agricultural chemicals as the raw material of home poultry raising it and cause death, even remote-effects are to people's health, and also can breed bacteria and virus after sometimes feed standing time is long, if it is not thorough to sterilize, can make and be doped with germ in the feed, if can cause poultry suddenly to dye disease for behind the poultry food, cause the large tracts of land of disease to spread, even whole plant caused serious economic loss, and traditional moise-heat sterilization mode can't satisfy people's demand, can not kill some germ, therefore not reach the effect of thorough disinfection.

Summary of the invention

The object of the present invention is to provide a kind of sterilization process of animal feed, its have workable, mode is scientific and reasonable, Environmental Safety, sterilization are thorough, the advantage that the nutriment in the protection feed is not damaged.

The sterilization process of a kind of animal feed of the present invention is characterized in that: this technique comprises following steps:

A. the gaseous ozone with high concentration is the high concentration liquid ozone through water mist sprinkling liquefaction, and concentration is 60%;

B. animal feed is dried, causing the humidity in the feed is 15%, feed after the drying is packed in the high pressure sealing disinfection tank, and stir to the high concentration liquid ozone that wherein adds simultaneously 30%-50%, passed into simultaneously the high concentration gaseous ozone 15-25 minute, stir feed when passing into, after 60-80 minute, adopt ultraviolet lamp to carry out sterilization processing;

C. add quaternary ammonium salt in disinfection tank, concentration is 0.5-1%;

D. sterilize complete after, pass into high-temperature steam 20-30 minute more than 200 ℃ in the disinfection tank, and stir simultaneously feed, making ozone reduction is oxygen, residual with thorough removing ozone;

E. after removing residual ozone, add active bacterium in the disinfection tank and carry out the fermentation of animal feed.

The beneficial effect of the sterilization process of a kind of animal feed of the present invention: the mode that the physical chemistry such as this craft science is reasonable, workable, Environmental Safety, employing ozone, ultraviolet lamp, quaternary ammonium salt mutually combine is carried out sterilization, not only sterilization thoroughly, simple operation, nontoxic, odorless, nonirritant, bactericidal properties be strong, and the nutriment in the assurance feed is not damaged, and increased the nutritional labeling of feed, for professional raising farmer provides safe and reliable feed, thereby guaranteed that economy do not suffer a loss.

The specific embodiment

Example 1.

The present invention relates to the sterilization method technical field of feed, be specially a kind of sterilization process of animal feed, concrete operating procedure is: (1) is the high concentration liquid ozone with the gaseous ozone of high concentration through water mist sprinkling liquefaction, and concentration is 60%; (2) animal feed is dried, causing the humidity in the feed is 15%, feed after the drying is packed in the high pressure sealing disinfection tank, and stir to the high concentration liquid ozone that wherein adds simultaneously 30%-50%, passed into simultaneously the high concentration gaseous ozone 15-25 minute, stir feed when passing into, after 60-80 minute, adopt ultraviolet lamp to carry out sterilization processing, can cause Cell Component, particularly nucleic acid, magma albumen and acid change, and cause microbial death; 3) add quaternary ammonium salt in disinfection tank, concentration is 0.5-1%, and toxicity and excitant are less, without bleaching and corrosiveness, and odorless, stable, good water solubility; (4) sterilization complete after, pass into high-temperature steam 20-30 minute more than 200 ℃ in the disinfection tank, and stir simultaneously feed, making ozone reduction is oxygen, residual with thorough removing ozone; (5) after removing residual ozone, add active bacterium in the disinfection tank and carry out the fermentation of animal feed.

Claims (1)

1. the sterilization process of an animal feed, it is characterized in that: this technique comprises following steps:

A. the gaseous ozone with high concentration is the high concentration liquid ozone through water mist sprinkling liquefaction, and concentration is 60%;

B. animal feed is dried, causing the humidity in the feed is 15%, feed after the drying is packed in the high pressure sealing disinfection tank, and stir to the high concentration liquid ozone that wherein adds simultaneously 30%-50%, passed into simultaneously the high concentration gaseous state 15-25 minute, stir feed when passing into, after 60-80 minute, adopt ultraviolet lamp to carry out sterilization processing;

C. add quaternary ammonium salt in disinfection tank, concentration is 0.5-1%;

D. sterilize complete after, pass into high-temperature steam 20-30 minute more than 200 ℃ in the disinfection tank, and stir simultaneously feed, making ozone reduction is oxygen, residual with thorough removing ozone;
