Feed acidifier coating preparation method

Abstract

The present invention discloses a feed acidifier particle material coating preparation method which contains the following specific steps as follows: (1) 10-12 parts of chitosan, 15-20 parts of citric acid, and 15-20 parts of malic acid are mixed and sieved through a 300 mesh, and 20-30 parts of lactic acid, 5-8 parts of polyethylene glycol are added and mixed evenly to conduct spray granulation; (2) 1-2 parts of formic acid, 12-15 parts of acetic acid, 3-5 parts of propionic acid, 10-15 parts of butyric acid, 10-12 parts of hydroxypropylmethylcellulose, and 2-3 parts of gaseous phase silica are mixed evenly with the granulated material obtained in the step (1), and the mixture is granulated using a screw extruder; and (3) 1-3 parts of fumaric acid, 5-10 parts of ethanol, 1-3 parts of benzoic acid, and 20-25 parts of molten polypropylene acid resin are uniformly mixed into a coating liquid to conduct coating. The preparation technology is simple, and the feed acidifier particle material is stable in performance and is easy in storage, has a long shelf life, has a significant effect in the protection of poultry and livestock digestive tract health, and can significantly improve the biological activity of poultry and livestock.

Description

technical field [0001] The invention relates to the technical field of coating in feed production, in particular to a coating preparation method of a feed acidifier. Background technique [0002] Acidulant is a commonly used feed additive, which can increase the acidity of feed, and the use of acidulant can reduce the pH value of animal gastrointestinal tract, thereby improving the mechanism of digestive activity of animal gastrointestinal tract, adding an appropriate amount of acidulant to livestock and poultry feed , can activate a variety of digestive zymogen activities, promote the digestion and absorption of nutrients and prevent diarrhea; reduce the impact caused by heat stress; reduce the risk of transmission of pathogenic bacteria such as E. coli and Salmonella. [0003] Among them, small molecular organic acids such as formic acid, acetic acid and propionic acid can not only reduce the pH value, but also inhibit Gram-negative bacteria; large molecular organic acids ...

Problems solved by technology

Due to the above problems, its application in feed is limited.

[0004] In the existing technology, in order to alleviate the strong irritation, corrosiveness, volatility and instability of the acidifier, easy to absorb moisture, and the influence of alkaline raw materials in the feed, it is difficult to avoid the influence of alkaline raw materials in the feed.

There are many different coating schemes, such as Chinese patent 2003101063387, this dosage form has a certain improvement on the effect of acidulant, but in the actual production, there are also defects of incomplete coating and high cost. The patent number is CN201110068163.X A compound protected acidulant is disclosed, the compound acidulant is completely covered by a coating material, so that the acidulant is slowly released in the gastric environment, and the animal's own gastric acid and pepsinogen are secreted The degree of influence is minimized, but the acidulant invented by this patent cannot play an optimal role in the intestinal tract
