Embodiment 1

[0021] 1. Weigh raw materials:

[0022]

[0023] All the above-mentioned raw materials can be purchased in the raw material market.

[0024] Second, the operation process steps are as follows:

[0025] (1) Preparation of homogeneous mixed phase: Heat and melt stearic acid to 80.0°C, add ultra-finely pulverized fumaric acid and citric acid powder into the melted stearic acid liquid, mix evenly, and use an emulsifying homogenizer to mix again Forced mixing, so that the fumaric acid and citric acid are evenly distributed in the stearic acid liquid phase;

[0026] (2) Cold air spraying into granules: Spray the stearic acid liquid, fumaric acid, and citric acid dispersion phase mixture into the swirling fluidized bed granulator. Wind quickly cools the sprayed droplets to form granules, and the particles of fumaric acid and citric acid are tightly wrapped in stearic acid;

[0027] (3) Carrier adsorption: Spray lactic acid and phosphoric acid liquid into the silica carrier, mix...

Abstract

The invention discloses a particle type compound acidifier and its preparation method. The particle type compound acidifier comprises the following raw materials in percentage by weight: 5.0%-8.50% of fumaric acid, 5.0%-8.50% of citric acid, 12.0%-15.0% of lactic acid, 12.0%-15.0% of phosphoric acid, 20.0%-25.0% of silicon dioxide, and 34.0%-45.0% of stearic acid. The preparation method comprises the following steps: heating the stearic acid to melt, mixing and homogenizing the molten stearic acid, the fumaric acid and the citric acid, cold-blast spraying into particles; mixing and absorbing the lactic acid, the phosphoric acid and the silicon dioxide into particles; uniformly mixing the above particles, and packaging the particle mixture to obtain the products of compound acidifier. The compound acidifier has proper ratio of gastric soluble acids to enteric acids, obvious reduces the pH value in stomachs of piglets and the pH value in intestines of piglets, promotes the activation of pepsinogen, increases the utilization efficiency of proteins, promotes the growth of probiotics such as Lactobacillus, suppresses the growth of contaminating microorganisms, reduces the use of antibiotics, reduces the occurrence of diarrhea of piglets, and increases the survival rate of piglets.

Description

technical field [0001] The invention belongs to the technical field of feed additive processing, and relates to a granular composite acidifier and a preparation method thereof. Background technique [0002] Compound acidifiers are additive products added to premixes, concentrated feeds and complete compound feeds, generally containing inorganic acids, organic acids and carriers. At present, inorganic acids include phosphoric acid, and organic acids include lactic acid, citric acid, and fumaric acid. Acidifiers are used in feed to reduce the pH value in the stomach, promote the activation of pepsinogen, and promote the digestion and absorption of nutrients. . [0003] Due to most acidifiers currently on the market, the process mostly adopts two forms. One is to use silica as the adsorption carrier to absorb liquids such as lactic acid and phosphoric acid, and then add some solid monomer acid powder for mixing; the other is to use some acidification The liquid acid is absorb...
