Embodiment 1

[0029] Prepare feed grade hydroxymethionine manganese chelate product A according to the following method:

[0030] (1) Dissolving the solid manganese sulfate monohydrate, removing the insolubles by means of pressure filtration to obtain manganese sulfate solution.

[0031] (2) Add sodium hydroxide solution to the manganese sulfate solution, collect the solid phase matter by pressure filtration after fully reacting, and then wash away the sodium sulfate contained in the solid phase matter, sodium hydroxide and other soluble substances by washing , using barium chloride to detect whether the sulfate radicals have been rinsed clean, to obtain water-washed slag.

[0032] (3) Transfer the water-washed slag into a reaction tank, and add clear water to homogenate. The manganese content of the extracted homogenate was 23.3% (mass percentage).

[0033] (4) By measuring the manganese content, the chelation reaction was carried out according to the molar ratio of manganese to hydroxym...

Embodiment 2

[0038] Prepare feed grade hydroxymethionine manganese chelate product B according to the following method:

[0039] (1) Dissolving solid manganese chloride tetrahydrate, removing insoluble matter by pressure filtration, to obtain manganese chloride solution.

[0040] (2) Add sodium hydroxide solution in the manganese chloride solution, collect the solid phase matter by press filtration after fully reacting, then wash the sodium chloride contained in the solid phase matter, soluble substances such as sodium hydroxide Rinse well to obtain washed residue.

[0041] (3) Transfer the water-washed slag into a reaction tank, and add clear water to homogenate. The manganese content of the extracted homogenate was 25.1% (mass percentage).

[0042] (4) By measuring the manganese content, the chelation reaction was carried out according to the molar ratio of manganese to hydroxymethionine of 1:2.1, the reaction temperature was 25°C, the reaction time was 20 minutes, the stirring speed w...

Abstract

The invention relates to a production method of a feed additive, and particularly discloses a preparation method of a feed-grade methionine hydroxy manganese chelate. The preparation method includes the steps that firstly, a metered sodium hydroxide reagent is added into an inorganic salt water solution of manganese, and a solid substance is obtained; secondly, the solid substance is washed to remove soluble components in the solid substance; thirdly, water is added into washing residues for homogenization; fourthly, 2-hydroxy-4-(methylthio)butyric acid is added for a chelation reaction, wherein the molar ratio of manganese in the homogenate to 2-hydroxy-4-(methylthio)butyric acid is smaller than or equal to 0.5; fifthly, the reaction product is subjected to aftertreatment to obtain the product. The method has the advantages that the methionine hydroxy manganese chelate product with higher purity can be prepared, and the product is more suitable for serving as a feed additive; the chelation reaction rate is high, the energy consumption is low, the chelation reaction can be conducted at a high rate at the normal temperature, and the production method is simple and easy to popularize in the industry.

Description

technical field [0001] The invention relates to the field of animal breeding, in particular to a preparation method of a feed additive. Background technique [0002] The main nutritional and physiological role of the trace element manganese is as an enzyme activator or component in the metabolism of carbohydrates, lipids, proteins and cholesterol. Manganese can participate in the transmission of central nervous media and the energy supply of central nervous cells, and it is an essential substance to maintain the normal metabolic function of the brain. If the animal is deficient in manganese, it can lead to decreased food intake, slowed growth, bone abnormalities, ataxia, and unresponsiveness and reproductive abnormalities. In addition, the synthesis of thyroid must be catalyzed by the enzyme that activates manganese. Manganese ions also have a lot to do with the color of the hair. If the hair is bright, it may contain enough manganese, and if the hair is dull, it may be de...
