Embodiment 1

[0017] Choose a solvent. The characteristics of the selected solvent are: ①dissolvable film material; ②does not dissolve the coated product; ③low boiling point, easily volatile when heated; ④does not chemically react with the coated product and film material.

[0018] The solvent can be selected from absolute ethanol, 95% ethanol, acetone or ethyl acetate. This embodiment uses acetone.

[0019] Choose membrane material. The characteristics of the selected membrane material are: ① soluble in the selected solvent; ② poor water solubility, no water absorption, no deliquescence; ③ no chemical reaction with the coated product; ④ good film-forming properties; ⑤ non-toxic, harmless.

[0020] The film material can be selected from ethyl cellulose, hydroxypropyl methyl cellulose, polyvinyl butyral or sodium carboxymethyl cellulose; hydroxypropyl methyl cellulose is used in this embodiment.

Abstract

The coated film-coated betaine or its salt and the coating process belong to the post-treatment process of chemical product betaine or its salt and betaine or its salt. It is coating betaine or betaine salt to form coating or coating betaine or its salt. The film forming process is: 1), weigh betaine or its salt and pour it into the film laminating machine, and control the temperature of the material at 40°C-70°C; 2), turn on the air compressor, control the pressure, and use a high-pressure spray gun to spray the Spray the film-forming agent on the surface of betaine or its salt crystals, control the temperature of the material and continue to heat and dry it, stop it for 30 minutes, discharge, sieve, and pack; the film-forming agent is made of a non-toxic film material dissolved in a solvent Uniform film solution with a concentration of 1%-10%; the weight gain of the product after coating is controlled at 0.5-5% according to the different requirements of different products. Suitable for betaine or its salt coating or coating.

Description

[0001] Field [0002] The invention relates to a chemical product betaine or its salt and a post-treatment process for betaine or its salt. Background technique [0003] Betaine belongs to quaternary ammonium substances, which can promote animal growth, maintain fat metabolism and normal liver function. Its existence forms include betaine anhydrous, betaine monohydrate, betaine hydrochloride, betaine phosphate, etc., and are mainly used in pharmaceuticals, food additives, feed additives, cosmetics and other industries. [0004] The betaine production method includes various chemical synthesis methods and extraction methods from natural products using glycine, choline and monochloroacetic acid as raw materials. At present, the betaine and its salts produced in my country and abroad are all uncoated products, which have some defects and deficiencies to varying degrees. Absorbs moisture from the air and dissolves. Betaine hydrochloride is very acidic, and its 25% aqueous soluti...
