preparation example Construction

[0024] The preparation method of zinc threonine for animal feed additive provided by the invention comprises the following steps:

[0025] 1) mixing threonine and zinc-containing materials evenly, then adding an aqueous solution of grinding aids, and performing wet ball milling to obtain slurry materials;

[0026] 2) dissolving the slurry material in water, filtering to obtain filtrate and precipitation;

[0027] 3) Add ethanol to the filtrate for recrystallization, filter, and flash dry to obtain zinc threonine.

[0028] Zinc-containing materials herein are limited to zinc sulfate or the group consisting of light zinc oxide and heavy zinc oxide, or zinc sulfate, light zinc oxide and heavy zinc oxide. Specifically, it includes three combinations: 1) threonine mixed with zinc sulfate; 2) threonine mixed with light zinc oxide and heavy zinc oxide; 3) threonine mixed with zinc sulfate, light zinc oxide and heavy Zinc oxide mix. Among them, zinc sulfate includes: zinc sulfate h...

Embodiment 1

[0048] With 680kg threonine, 30kg light zinc oxide, 87kg heavy zinc oxide, 702Kg zinc sulfate heptahydrate (threonine: light ZnO: the mol ratio of heavy ZnO and zinc sulfate heptahydrate is 1.4: 0.1: 0.3: 0.6) After mixing, add it to the silo of the wet continuous ball mill, so that the silo can be fed evenly and uninterruptedly. At the same time, add 988g of grinding aid into 2 cubic water tanks to make an aqueous solution, stir well with a mixer, and then measure The pump evenly pumps the aqueous solution of the grinding aid into the ball mill from the working water tank to keep the water content of the reaction material in the driving cylinder at about 2% to 20%. Dissolve the milled slurry in water and filter. After the filter is drained and mixed with other dry raw material powders, it is added to the silo of the wet continuous ball mill to continue the reaction. The filtrate is recrystallized by adding ethanol, filtered, and the filtrate is flash-dried and sieved to obta...

Embodiment 2

[0051] Mix 303kg of threonine, 52kg of light zinc oxide, and 22kg of heavy zinc oxide (the molar ratio of threonine: light ZnO: heavy ZnO is 2.5:0.7:0.3) and add it to the silo of the wet continuous ball mill In the process, feed the silo evenly and uninterruptedly. At the same time, add 1kg of grinding aid to 2 cubic water tanks to make an aqueous solution. After fully stirring with a mixer, use a metering pump to feed the aqueous solution of the grinding aid. The aqueous solution is taken from the working water tank. Evenly pour into the ball mill, and keep the water content of the reaction material in the driving cylinder at about 2% to 20%. Dissolve the milled slurry in water and filter. After the filter is drained and mixed with other dry raw material powders, it is added to the silo of the wet continuous ball mill to continue the reaction. The filtrate is recrystallized by adding ethanol, filtered, and the filtrate is flash-dried and sieved to obtain threonine zinc. Ga...

Abstract

The invention provides a threonine-zinc mixed material for an animal feed additive and its preparation method and use. The preparation method comprises the following steps of uniformly mixing threonine and zinc-containing materials to obtain a mixture, carrying wet ball milling of the mixture with addition of an auxiliary agent aqueous solution to obtain a threonine-zinc mixed pasty crude product, and carrying out purification of the threonine-zinc mixed pasty crude product to obtain the threonine-zinc mixed material. The preparation method provided by the invention improves reaction efficiency, has simple processes, can be carried out at a normal temperature and saves energy.

Description

technical field [0001] The invention relates to the field of feed addition, in particular to a preparation method of zinc threonine used as an animal feed additive. In addition, the present invention also relates to an application of zinc threonine prepared by the above-mentioned preparation method. Background technique [0002] As an amino acid for feed, threonine has been widely used in piglet feed, breeding pig feed, broiler chicken feed, prawn feed and eel feed. As an animal feed additive, threonine can adjust the balance of amino acids in the feed and promote animal growth; it can improve meat quality; it can improve the nutritional value of animal feed raw materials with low amino acid digestibility; it can be used to produce low-protein feed, which helps to save Protein resources; can reduce the cost of animal feed raw materials; can reduce the nitrogen content in livestock manure and urine, the concentration and release rate of ammonia in livestock and poultry house...
