Feed composite protection type acidulant and production method thereof

Abstract

The invention relates to a feed composite protection type acidulant which comprises 8-15wt% of phosphoric acid or pyrophosphoric acid, 10-20wt% of citric acid, 15-25wt% of fumaric acid, 8-15 wt% of malic acid and 30-60 wt% of stearic acid or monostearate or bistearate, wherein the phosphoric acid or pyrophosphoric acid is absorbed and uniformly mixed with the citric acid, the fumaric acid and themalic acid, and the stearic acid or the monostearate or the bistearate is used as a coating wrapped outside. The invention further provides a production method of the feed composite protection type acidulant. The use value and the use effect of the feed acidulant product are improved, and the production loss is reduced.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to the technical field of feed acidifiers, in particular to a feed compound protective acidifier and a production method thereof. Background technique [0002] At present, the raw material selection of feed acidifier is mainly: 1) main acid raw materials: phosphoric acid, lactic acid, fumaric acid, citric acid, benzoic acid, formic acid, propionic acid, butyric acid; 2) organic acid salts: calcium lactate, calcium formate; 3) Accessory materials: diatomaceous earth, white carbon black. At present, there are mainly the following two processing techniques and related formulas: [0003] 1. Adsorption mixed type [0004] Proportion 1 ( Inorganic type ): phosphoric acid 30-60% (weight), lactic acid (or formic acid, propionic acid) 5-10% (weight), diatomite (or white carbon black) 30-45% (weight); [0005] Proportion 2 ( organic model ): 20-40% (weight) of lactic acid, 15-25%...

AI Technical Summary

Problems solved by technology

It can be seen from the above that the equipment process is simple adsorption and mixing, and the active ingredients of the products produced cannot be effectively protected, and the following problems will occur during the use of the products:

[0010] 1) Low melting point, volatile active ingredients (such as: formic acid, propionic acid, etc.) are easily lost during processing, storage and use, and the stability of product quality cannot be effectively guaranteed;

[0011] 2) The unprotected active ingredient (acid) will react with other alkaline nutrients in the feed, thereby reducing the potency of nutrition in the feed, and the stability of the quality of the feed product cannot be effectively guaranteed;

[0012] 3) Some active ingredients (such as: phosphoric acid) are medium-strong acids with strong corrosiveness. Phosphoric acid without effective protection will damage the oral mucosa of animals and affect the palatability of feed to a certain extent, thereby affecting the feed intake of pigs;

[0013] 4) Acidifiers that have not been effectively treated will be released immediately after entering the animal body, thereby affecting the secretion of gastric acid and pepsin of the animal itself

[0019] The problems that the above-mentioned formula exists are: a) due to the impact of the process, the selection of raw materials is relatively single, and the total amount of H+ released by the formula itself has a small change with the pH; b) affected by the adsorption material, the total acid content in the formula The amount is low, and the added amount of the product is relatively high

[0022] a) Due to the characteristics of the raw material itself, the product will be pulverized during the process of adsorption and mixing, which not only affects the appearance of the product but also has a certain impact on the use effect of the product;

[0023] b) About 0.5-1% of the dust produced during the coating process can only be treated as waste because the instability of its quality will affect the use effect of the product, and the processing loss of the product is large (up to 1.2%);

[0024] c) The coating process will cause agglomeration due to changes in external temperature, humidity and peristaltic pump peristaltic speed, which will not only affect the appearance of the product but also affect the application effect of the product itself to a certain extent;

[0025] d) Because the active ingredients are all liquid, the content of the active ingredients will be affected by the adsorption value of the adsorption material, and the requirements for the adsorption material are relatively high, which brings certain difficulties to the realization of procurement;

[0026] e) The overall process cannot achieve continuous production, and the semi-finished products of adsorption and mixing need to go through an aging period of more than 8 hours;

[0027] f) The acidity of the semi-finished product after adsorption is high, and the dust generated during packaging has certain hidden dangers to the health of operators
