Preparation method and preparation device of choline chloride powder

Abstract

The invention discloses a preparation method and a preparation device of choline chloride powder. The preparation method includes: obtaining choline chloride water of 50-80% in weight percentage of choline chloride; adding a spray auxiliary into the choline chloride water, and mixing and stirring well, wherein adding quantity of the spray auxiliary is 2-15% of weight of the choline chloride water; pumping the choline chloride water added with the spray auxiliary into spray drying equipment for spray drying; step 4, feeding choline chloride dried powder into a mixing tank, adding one of or a mixture of multiple of potassium ferrocyanide, sodium silicoaluminate, tricalcium phosphate, silica, microcrystalline cellulose and calcium stearate accounting for 3-30% of weight of the choline chloride dried powder, and stirring and mixing to obtain the choline chloride powder. The preparation device comprises an air feeding system, a liquid feeding system, a spray drying system, a mixing system, a tail gas treatment system and a pipeline. The preparation method and the preparation device have the advantages of quickness in drying and low energy consumption.

Description

technical field [0001] The invention relates to the field of food additives, in particular to a method and device for preparing choline chloride powder. Background technique [0002] Choline (scientific name 2-hydroxyethyl-trimethylcholine hydroxide), a kind of vitamin B. Choline can promote fat metabolism in the liver and kidney; choline is also the basis for the body to synthesize acetylcholine, thereby affecting the transmission of nerve signals. In addition, choline is also one of the methyl sources required for the synthesis of methionine in the body. Natural choline is contained in many foods, but its concentration is not enough to meet the needs of the modern feed industry for the rapid growth of animals, so synthetic choline should be added to the feed to meet its needs. Lack of choline can lead to fatty liver, slow growth and increased death in poultry and livestock. Choline chloride is the hydrochloride of choline. In general animal rations, it has been widely u...

AI Technical Summary

Problems solved by technology

However, the existence of small wrinkle openings or small channel holes on the carrier will consume a lot of energy and time for drying, and the production cycle will be longer

[0009] Second, the product shelf life is short

When the carrier is dried, there is still a small amount of water in the openings of small wrinkles or small pores and caves that have not been dried, and the powder may deteriorate during long-term storage, affecting product quality

In particular, the choline chloride powder using plant-based carriers will also produce moisture absorption and deterioration, which will affect product quality.
