Problems solved by technology

However, there is no report on the use of hydrochloric acid in conjunction with commonly used organic acids. The main reason is that hydrochloric acid is highly volatile and corrosive, and it is difficult to handle in the production process.

Abstract

The invention provides a feed acidifying agent and a preparation method thereof. The feed acidifying agent comprises 1-10 wt% of hydrochloric acid, 20-80 wt% of an organic acid, 1-30 wt% of bentonite,5-30 wt% of a filler and 5-30 wt% of a coating material. The preparation method comprises the following steps: 1) adding the hydrochloric acid and bentonite into a mixer, and uniformly mixing the hydrochloric acid with bentonite; 2) adding the organic acid and the filler into the mixer, and uniformly mixing above materials to obtain a soft material; 3) placing the soft material prepared in step 2) in a swing machine, and swinging the soft material by a screen to prepare granules; 4) drying the granules obtained in step 3) in a boiling bed, and allowing the dried granules to go through a screen; and 5) processing the coating material to form a coating solution, placing the granules in a coating pan, coating the granules by using the coating solution, drying the coated granules after spraying of the coating solution is completed, and allowing the dried coated granules to go through the screen in order to obtain the feed acidifying agent. The hydrochloric acid and the organic acid are successfully cooperatively used to make the acidifying agent have a good pH value adjusting effect, and has a stronger inhibition effect on existing acidifying agents.

Description

technical field [0001] The invention belongs to the technical field of acid preparations, and in particular relates to a feed acidifier and a preparation method thereof. Background technique [0002] Feed acidifier is an important additive after antibiotics, alongside probiotics, enzyme preparations, and microecological preparations. It is an environmentally friendly additive with no residue, no drug resistance, and no toxic effects. Feed acidifier, as a new type of additive that can reduce the pH value of feed in the digestive tract and provide the most suitable digestive tract environment for animals, has been widely used at home and abroad. Acidifiers are widely used in the feed of poultry, piglets, beef cattle, dairy cows, sheep and other animals. [0003] Feed acidifiers are mostly used in combination with organic acids and inorganic acids, because the combined use of the two can achieve complementary synergistic effects and overcome the shortcomings and defects of a s...
