Composition containing potassium butyrate, preparation method and application thereof in feed additives

Abstract

The invention discloses a composition containing potassium butyrate, which is prepared by combining 0.5 to 95 percent of potassium butyrate and 5 to 99.5 percent of dispersant. A preparation method of the composition comprises the steps of: preparing the potassium butyrate first; and then mixing the potassium butyrate and the dispersant evenly according to the proportion to obtain the composition containing the potassium butyrate, wherein a method for preparing the potassium butyrate comprises the steps of: performing an acid-base reaction, namely adding 1,000 weight portions of water and 445 weight portions of potassium hydroxide into a reaction tank; stirring the mixture until the mixture is dissolved; adding 698 weight portions of butyric acid into the mixture, controlling the temperature to be not higher than 105 DEG C; cooling a reaction liquid to a temperature between 25 and 80 DEG C after the reaction is finished; adjusting the pH value to between 8 and 11,and continuously cooling the reaction liquid to a temperature of between 25 and 50 DEG C; filtering the reaction liquid; performing spray drying, wherein the air inlet temperature is between 150 and 260 DEG C and the air outlet temperature is between 65 and 160 DEG C; and obtaining the potassium butyrate by the collection of a cyclone separator or a vibrated fluidized bed. The invention can effectively prevent composition products from agglomerating and caking, ensure that the composition products are easy to store and use, is applied to feed additives, and can increase the nutrient value of feeds.

Description

technical field [0001] The invention relates to a composition containing potassium butyrate, in particular related to the ratio of the composition, the preparation method of the composition and the application of the composition in animal feed additives. Background technique [0002] Butyric acid and its derivatives such as sodium butyrate and glyceryl butyrate are allowed to be added to feed to improve animal performance, mainly to provide rapid energy for animal intestinal epithelial cells. [0003] Potassium ions are the most important cations in intracellular fluid, which can regulate tissue osmotic pressure and acid-base balance, and are an important factor in maintaining the water capacity of cells and tissues. The dietary electrolytes that affect acid-base balance in animals are the monovalent potassium (K), sodium (Na) and chloride (Cl) ions. Dietary electrolyte balance (DEB) refers to the value calculated by the K+Na-Cl equation of the milliequivalents of these thr...

Problems solved by technology

However, potassium butyrate is very easy to absorb moisture or agglomerate. Even if the freshly produced potassium butyrate powder is stored in an airtight and moisture-proof storage condition with a moisture content of less than 1%, it will gradually agglomerate by itself within a few hours. group, which is not conducive to storage and use, greatly hindering the production and application of potassium butyrate
