Method for coating acidifier used in feed

Abstract

The invention provides a method for coating an acidifier used in feed. The method comprises the following steps of: taking porous acid-resistant adsorption particles with micro holes, and conducting mixing dispersion on the particles and organic acid so as to obtain an acidifier dispersoid; and conducting mixing dispersion on the acidifier dispersoid and adhesive micro powder with a particle sizenot larger than that of the micro holes, so that the adhesive micro powder adheres and closes the micro holes, and the coated acidifier used in feed is obtained. According to the invention, after theorganic acid is adsorbed by the porous acid-resisting adsorption particles with micro holes, the adhesive micro powder with fine particle size and good adhesion effect is used for secondary mixing dispersion so as to adhere and close the micro holes, so that the coating of the organic acid is realized. The method provided by the invention does not need special coating equipment, raw materials andauxiliary materials are simple and easy to obtain, the cost is low, the production energy consumption is low, the stability of the processed coated acidifier is good, the technical difficulty is low,and the process is simple and free from safety risk.

Description

technical field [0001] The invention belongs to the technical field of feed processing, in particular to a method for coating an acidifier for feed. Background technique [0002] Young animals generally have the problem of insufficient development of digestive function; under the requirements of high production efficiency, the feed intake of appropriate-age animals is required to be as large as possible to improve production performance; a large amount of feed intake by animals leads to an increase in the pH value of the stomach, which makes pepsin activity Therefore, the addition of acidifiers can help to improve the digestibility of feed, especially for young animals and feeds with high nutrient concentration, acidifiers are generally added, which not only improves the digestibility of animals, but also is important to prevent diseases and reduce An important means of adding antibiotics. [0003] As an important and safe feed additive, acidifier has the characteristics of...

AI Technical Summary

Problems solved by technology

[0003] As an important and safe feed additive, acidifier has the characteristics of no pollution and no residue, and has received widespread attention and application in the industry. The scope of use is still expanding, and it is mostly added in the form of organic and inorganic acids. In order to enhance the use effect; but there are obvious problems in actual use. On the other hand, the acidifier itself also has a certain corrosion on equipment and facilities, which will rust the production equipment and cause unnecessary damage.

[0004] At present, the treatment methods for acidulants mainly include thermal processing, fat or resin coating, which need to use oven drying and heating equipment, fluidized bed, spray drying tower, reaction kettle and other equipment. Dehydration, surface coating, etc. are used to reduce or mitigate the negative effects of the acidifier during use. The existing treatment methods require special equipment and high energy consumption. Large-scale production requires a large investment in equipment and complicated processes. , the technology is difficult, the stability is poor, and some processes have certain safety risks due to the use of volatile high-explosive solvents
