Embodiment 1

[0032] Put 190kg of palm oil at 52°C, 15kg of hydrogenated vegetable oil, 40kg of palm wax, and 25kg of sorbitan fatty acid ester into a 500L reactor with a steam interlayer, heat it to 95°C with steam, stir continuously to dissolve it completely, and add 25kg of feed Grade zinc oxide, 5kg nano-zinc oxide, continue to keep warm at 85°C to 95°C, stir to form a uniform suspension. Release the molten liquid from the outlet, form a thin layer on the stainless steel plate, and blow cold air on the other side of the plate to make it quenched into a solid, and continue to cool at room temperature for 60 minutes. It is pulverized by a hammer mill, passed through a 20-mesh sieve, and the under-sieve is taken to obtain the finished product.

[0033] The process parameters of the reactor: the speed is 150 rpm, the steam temperature is 120°C;

[0034] The process parameters of the blower are: air flow, 2000m 3 / h;

[0035] The process parameters of the hammer mill are: speed 2800r / min....

Embodiment 2

[0037] Put 190kg of 52°C palm oil, 15kg of hydrogenated vegetable oil, 40kg of palm wax, and 25kg of sorbitan fatty acid ester into a 500L reaction kettle with a steam interlayer, heat it to 95°C, stir continuously to dissolve it completely, and add 25kg of feed grade zinc oxide , 5kg nano zinc oxide, continue to keep warm at 85 ℃ ~ 95 ℃, stir to make a uniform suspension. Move the molten liquid into the liquid storage tank at 90°C, stir and keep it warm, drop it into the flowing circulating cooling water from the dropping pill machine, take it out, blow off most of the surface water with a blower, dry it in air, pass through a 20-mesh sieve, and take the sieve to get the finished product .

[0038] The process parameters of the reactor: the speed is 150 rpm, the steam temperature is 120°C;

[0039] Process parameters of the dropping pill machine: porous dripper, the inner diameter of the dripper is 0.8mm, and the dripping speed of each hole is about 100 pills / min;

[0040] ...

Embodiment 3

[0042] Put 2.85kg 52℃ palm oil, 0.5kg hydrogenated vegetable oil, 0.5kg beeswax, 0.15kg sorbitan fatty acid ester, 6kg nano-zinc oxide in a hot kneader, heat to 85℃~95℃, and knead to form a uniform The soft material is moved into a swinging granulator for granulation, and the obtained granules are scattered and cooled by a blower, placed at room temperature for 60 minutes, then pulverized by a hammer mill, passed through a 20-mesh sieve, and the sieve is taken to obtain the finished product.

[0043] Thermal kneader process parameters:

[0044] The process parameters of the swing granulator are: drum speed 100r / min;

[0045] The process parameters of the blower are: air flow, 2000m 3 / h;

[0046] The process parameters of the hammer mill are: speed 2800r / min.

Abstract

The invention discloses coated zinc oxide with high stomach passing rate and a preparation method of the coated zinc oxide. The coated zinc oxide with the high stomach passing rate consists of the following components in parts by weight: 10-70 parts of zinc oxide and 30-90 parts of a composite coating material. The composite coating material consists of the following components in parts by weight: 70-90 parts of a lipid main material, 9-20 parts of a toughening agent and 1-10 parts of a dispersing agent. The preparation method comprises the following steps: mixing, shaping and granulating. Lipid is used as the main material, meanwhile, the toughening agent and the dispersing agent are added, in the preparation method, the zinc oxide is coated by a solid dispersing technology and then is granulated, the physical damage resistance of the product is remarkably improved, the stomach passing rate of the zinc oxide reach 90% or above, and therefore, the zinc oxide can be completely and slowly released in the intestinal tract.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a coated zinc oxide with a high rate of excess stomach and a preparation method thereof. Background technique [0002] Zinc oxide has the effect of inhibiting the growth of bacteria, and is generally used in animal production to control diarrhea that may occur during the rapid growth of suckling piglets. High doses of zinc oxide added to traditional dosage forms can effectively control diarrhea in piglets, but animal nutrition and physiological experiments have proved that the dissociation degree of zinc oxide in traditional dosage forms is as high as 90% under gastric acid conditions, and excessive dissociated zinc ions enter the intestinal tract of animals, resulting in zinc Poisoning, and competitively inhibit the absorption and transport of other nutrients, destroy the metabolic balance of trace elements in animals, affect the normal physiological activities of animals, cause an...
