Embodiment 1

[0033] A coated cysteamine hydrochloride, consisting of the following components by weight:

[0034] 35 parts of cysteamine hydrochloride, 13 parts of stearic acid, 12 parts of cellulose aqueous solution with a methylcellulose content of 5 wt%, 4.5 parts of citric acid, and 32 parts of white carbon black. The initial content of cysteamine hydrochloride was 51.7%.

[0035] Preparation:

[0036] The first step: Production preparation: 1. Dissolve 5 wt% of cellulose in warm water at 60-70°C 48 hours in advance, and stir frequently to fully dissolve it to form a cellulose aqueous solution; 2. Add stearic acid Heating and melting into a liquid state for use; 3. Breaking the massive cysteamine hydrochloride into moderately small pieces;

[0037] The second step: Grinding process: Weigh various raw materials according to the ratio in the formula, and add them to the colloid mill for grinding in the order of stearic acid - cellulose aqueous solution - cysteamine hydrochloride - citr...

Embodiment 2

[0041] A coated cysteamine hydrochloride, consisting of the following components by weight:

[0042] 29 parts of cysteamine hydrochloride, 17 parts of stearic acid, 14 parts of cellulose aqueous solution with a methylcellulose content of 5 wt%, 5.5 parts of citric acid, and 38 parts of white carbon black. The initial content of cysteamine hydrochloride was 28%.

[0043] The preparation method is the same as in Example 1.

Embodiment 3

[0045] A coated cysteamine hydrochloride, consisting of the following components by weight:

[0046] 32 parts of cysteamine hydrochloride, 15 parts of stearic acid, 13 parts of cellulose aqueous solution with a methylcellulose content of 5 wt%, 5 parts of citric acid, and 35 parts of white carbon black. The initial content of cysteamine hydrochloride was 32%.

[0047] The preparation method is the same as in Example 1.

Abstract

The invention relates to a coated cysteamine hydrochloride in the technical field of the coating of the cysteamine hydrochloride. The coated cysteamine hydrochloride comprises the following components in parts by weight: 29-35 parts of cysteamine hydrochloride, 13-17 parts of stearic acid, 12-14 parts of cellulose aqueous solution with methylcellulose content of 5 wt%, 4.5-5.5 parts of citric acid and 32-38 parts of white carbon black. The preparation method comprises the following steps of: weighing raw materials; adding the stearic acid, the cellulose aqueous solution, the cysteamine hydrochloride and the citric acid to a colloid mill in sequence to be ground into milk-white liquid; adding the liquid to the white carbon black in a stirring state so as to obtain white bulk granular powder; and screening the powder by using a screen of 0.3 mm. The coated cysteamine hydrochloride and the preparation method thereof, provided by the invention, have the advantages of simple process, cheapraw material, low production cost, high finished product rate and no generation of substances like waste gas, wastes and the like; therefore, no environment pollution is caused, the stability problemof the cysteamine hydrochloride is solved, and no great irritation can be caused to the stomach while the coated cysteamine hydrochloride is taken for a long time.

Description

Technical field [0001] The invention involves the technical field of cysteine hydrochloride, which specializes in a paddy campamine hydrochloric acid, and also involves the preparation method of this packet to be cysteine hydrochloride. Background technique [0002] Cygamine hydrochloride is an additive that is allowed to be used in livestock and poultry feed in documents issued by the Ministry of Agriculture (2006). [0003] Cygenromine, also known as β-cymbal acetic acid, is equivalent to the decarboxyle product of cysteine, is part of the coenzyme A molecule, and is a biological active substance in the animal. It has an important physiological role in the body.Source Add cosmoamine can exhaust the body growth of the body (SS) .sS was originally a 14 peptide (Brazeau, 1973) separated from the lamb mound brain.In the pancreatic and digestive tract. In addition to regulating the secretion of the growth hormone secretion of the pituitary gland, it also inhibits tissue endocrine a...
