Problems solved by technology

The raw material for the production of soybean polysaccharides is soybean dregs, the residue of soybean protein production. After repeated purification, the soybean dregs produce a suspension slurry containing fiber, soybean protein and soybean polysaccharides. After adding diatomite filter aid, the fibers and soybean protein are aggregated in diatomite Around the particles, a large particle suspension that is easy to filter is formed. After filtration, soybean polysaccharide solution and waste diatomaceous earth are obtained. Therefore, the waste diatomaceous earth is mainly composed of fiber, soybean protein and diatomite. Due to the adsorption of diatomite after one use A large amount of protein and other organic matter and water change from powder to slurry or paste, which is difficult to reuse, and the quality is greatly increased, becoming a solid waste that is difficult to handle
Due to the presence of organic matter and moisture, waste diatomaceous earth is very easy to deteriorate and emit foul smell, and its storage has become a difficult problem to solve
[0005] At present, the high-density feeding method in industrial farms makes a large number of animals continuously raised in one space, coupled with frequent turnover, resulting in a bad microclimate environment for high-density animals, which often causes animal stress responses and declines in body immunity , infected with various diseases or stimulate respiratory and digestive tract diseases, resulting in slow growth of animals, lower litter (egg) rate, increased death, delayed listing, lower feed return rate, increased feeding costs, etc., increasing the management of breeders Difficulty, economic loss
In order to solve the above problems, people have to use various antibiotic drugs to control, but there will be problems such as drug residues
This method of fighting fire with fire will not only produce a vicious circle effect, but also reduce the quality of meat and eggs

Embodiment 1

[0019] Example 1: After dehydration, the diatomite with a solid content of 35% in solid content and a water content of 65% was dried at a temperature of 100°C for 20 hours to control the water content below wt 5%. The trough mill disc flour mill crushing equipment crushes the diatomite to below 100 mesh.

[0020] The product diatomite is more than 25% based on silicon dioxide, organic matter such as crude protein and fat is more than 65%, and moisture is less than 6%, which meets the requirements of common feed.

Embodiment 2

[0021] Example 2: The waste diatomite produced in a soybean processing process in Pingdingshan City, with a solid content of 25% and a natural moisture content of 75%, was dried in an oven at 100° C. for 25 hours to a moisture content of 5%. Diatomaceous earth is pulverized to an average particle diameter of 130 microns and screened with an electric sieve using a coarse pulverizing device with a spindle speed of 500r / min;

[0022] The product diatomite is more than 27% in terms of silicon dioxide, organic matter such as crude protein and fat is more than 60%, and water is less than 6%, which meets the requirements of common feed.

[0023] Food-grade active diatomaceous earth is used as a feed additive: it is advisable to add it in a proportion of 1% to 15% by feed weight. Feed production enterprises can add and mix evenly according to the above ratio during the production process. Breeding enterprises and farmers can add feed according to the above ratio and method after purc...

Embodiment 3

[0024] Embodiment 3: (chicken feed is mixed with diatomite as the main feed additive and selects 8%) every group of 100 experimental chickens, divided into 2 groups, the experimental time is 6 months, the addition of special diatomite powder in the feed 10% respectively. The results show that: chicken feed mixed with diatomaceous earth as the main feed additive and choose 10% has a better effect. The survival rate of special diatomite powder was 94%, which was 88% higher than that of the control group. It shows that adding the feed additive prepared from waste diatomaceous earth has the most obvious effect on inhibiting poultry diseases.

Abstract

The invention relates to a method for preparing an animal feed additive from waste diatomite and application of the animal feed additive.The method includes: drying dewatered waste diatomite with solid content higher than wt20% and water content being wt70%-80% at 100-200 DEG C for 20-35h to control the water content below wt5%; using grinding equipment for grinding the dried diatomite into particles smaller than 100-mesh particles; adding according to a ratio of 1%-15% of the weight of feeds for livestock and poultry.Technical simplicity in production, sufficient raw material resources and low product cost are realized; the food safety problems caused by drug residues and drug resistance of pathogenic microorganisms can be effectively avoided, quality and output of livestock and poultry are improved, raising cost is reduced, absorption and appetite of animals can be promoted, and disease-resistant immunity is improved; the problems of environment pollution and residues caused by adoption of chemical insecticides in the breeding industry are effectively improved, and people's life quality is improved.

Description

technical field [0001] The invention relates to the field of animal feed additives, in particular to a method for producing feed additives using waste diatomite produced in the soybean protein production industry, and in particular to a method for using waste diatomite to prepare animal feed additives and its application. Background technique [0002] Diatoms are single-celled algae with extremely small shapes, and their shapes are generally only a dozen to tens of microns. Their remains are deposited to the bottom of the water and buried, and when they accumulate to a certain thickness, diatomaceous earth is formed. Its chemical composition is mainly silica, and its mineral composition is opal and its variants. Silica in diatomaceous earth is different from silica in other minerals and rocks in structure and composition. He is an amorphous opal mineral of organic origin, commonly known as diatomaceous silica. In addition to water and silicon dioxide, it also contains a sm...
