preparation example Construction

[0039]The present invention also provides a method for preparing the coated tannin pellet feed additive, comprising the following steps:

[0040] (1) tannin and diluent are mixed to obtain solid base material, and the solid base material of 15~25% of the total mass of solid base material is used as basic solid base material;

[0041] (2) The adhesive is mixed with water to obtain an aqueous adhesive solution, the aqueous adhesive solution is sprayed on the surface of the basic solid base material, the remaining solid base material is sprinkled while the aqueous adhesive solution is sprayed, centrifugal granulation, and granulation , drying and sieving to obtain tannin pellets;

[0042] (3) the hot-melt coating film is dissolved, followed by adding a plasticizer and a controlled release agent, mixing to obtain an outer coating layer, and uniformly coating the outer coating layer on the surface of the tannin pellet core particles to obtain tannin pellets Feed additives.

[0050] 190kg of tannin and 25kg of crospovidone were weighed and mixed uniformly to obtain a mixed solid base, and 43 kg of the mixed solid base was weighed in a centrifugal granulator. Weigh 2.5kg of hydroxypropyl cellulose and 60kg of water, stir and mix to obtain the adhesive, turn on the centrifugal granulator, the chassis speed is 250r / min, the blast frequency is 23Hz, and the adhesive is evenly sprayed on the surface of the solid base material Start centrifugal granulation, the atomization pressure is 0.08MPa, slowly sprinkle the remaining solid base material while spraying the binder, and the spraying speed is controlled at 9-14mL / min (adjust at any time according to the granulation state). After the centrifugal granulation is completed, the granulation is carried out. The granulation time is 4 minutes, and then it is dried at 40 ° C for 2.5 hours. After drying, it is passed through a 16-mesh and 30-mesh double-layer vibrating sieve, and the components in the sieve are c...

Abstract

The invention provides a coated tannin pellet feed additive, and relates to the technical field of feed additives, the feed additive is prepared from the following raw materials by mass: 70-80 parts of tannin, 10-15 parts of an auxiliary agent and 10-15 parts of an outer coating layer; the tannin and the auxiliary agent are granulated to obtain the pellet core, and the pellet core is coated with the outer coating layer; the tannin is added into pig feed instead of antibiotics or part of zinc oxide, so that the tannin is prevented from being released in the stomachs of pigs to be combined with effective substances in the stomachs so as not to reduce digestion and absorption of the effective substances, the tannin is released after reaching intestinal tracts, and the effects of stopping diarrhea, inhibiting bacteria, resisting oxidation, resisting viruses and resisting parasites of the tannin are exerted.

Description

Technical field [0001] The present invention relates to the technical field of feed additives, and in particular to a coated tannin pellet feed additive and a preparation method thereof. Background technique [0002] With the advent of the era of "banning antibiotics and limiting zinc" in feed, it has become an urgent issue to re-select a natural additive to replace antibiotics or partial zinc oxide to protect animal health and promote animal growth. [0003] Tannin is a natural polyphenolic compound that is a secondary metabolite of plants and is widely found in the roots, bark or fruits of legumes, gallnuts, chestnuts, sorghum, pomegranates, red bean grass, tea, cocoa and rapeseed. . In recent years, a large number of studies have found that tannins have strong astringent, anti-diarrheal and antibacterial effects. The main mechanism of action is: after tannins reach the small intestine, they coagulate proteins on the inflammatory surface of the small intestine, reduce inf...
