Abstract

The invention discloses a fodder acidifying agent coated with fat. The fodder acidifying agent is prepared according to the following steps: firstly compressing such a solvent at gaseous state at normal temperature and under normal pressure as liquefied oil gas into liquid and storing in a storage tank; dissolving a coating material such as hydrogenated vegetable oil into the liquid solvent; uniformly mixing a solution containing the coating material with an acidifying agent particle material in a pressure container so that the surfaces of acidifying agent particles are uniformly coated with the coating material; stirring and decompressing to release the solvent, and finally collecting a coated acidifying agent. The fodder acidifying agent disclosed by the invention has the advantages that a fat-soluble coating of the fodder acidifying agent is prepared by use of a subcritical fluid coating technique and the process is simple; the weight percentage of the acidifying agent in the coated acidifying agent is as high as 80%, so the coating materials are greatly saved and the production cost is lowered.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed acidifier with a fat coating. Background technique [0002] In the feed industry, antibiotics are a commonly used drug, which can effectively prevent the infection of animal intestinal pathogens and promote the healthy growth of animals. However, the abuse of antibiotics has become an important hidden danger affecting food safety, so reducing or even replacing the use of antibiotics is of great significance for improving the quality of meat products and ensuring the health of consumers. Studies have shown that the pH value in the animal intestine is of great significance to inhibit pathogenic bacteria. Therefore, it has become a common method to use acidifiers in the feed industry to change the pH value in the animal intestine. Currently commonly used acidulants include citric acid, malic acid, lactic acid, calcium lactate, fumaric acid, potassium diformate, calcium formate, sodium but...
