[0002] Arginine is a high-tech product, which is widely used in medicine, food, agriculture and other industries. It has the characteristics of high technical content, wide application range, and good use effect. At present, the preparation process of arginine in China is complicated, and the waste rate of raw materials is high. The yield is low, and there is an urgent need for an arginine preparation process with simple process and high raw material utilization rate to enhance its market competitiveness, reduce the import of similar foreign products, and meet market demand

Embodiment approach
[0012] The preparation method is specifically as follows: the hair that meets the requirements is rinsed, filtered, and dried to remove impurities and ash, and the raw materials that meet the requirements are obtained, and the raw materials and hydrochloric acid are mixed in a ratio of 1:2.5 and placed in a hydrolysis kettle at a ratio of 1%. Add a hydrolysis aid, keep the temperature at 60-70°C, and keep it warm for 2.5 hours to make the raw material react with hydrochloric acid completely, filter the hydrolyzed mixed solution with suction, put the filtrate into the filtrate tank, and further filter the remaining billet by 1:2 Mix it with hydrochloric acid, add a hydrolysis aid at a ratio of 1%, keep the temperature at 70-80°C, keep warm for 2 hours, filter the mixture with suction, pour the filtrate into the filtrate tank, and then pass it into hydrochloric acid at a ratio of 1:0.8. Add a hydrolysis aid in a proportion of 1%, keep the temperature at 70-80°C, keep it warm for ...

The invention relates to a method for preparing arginine, which is mainly used for preparing the arginine. The preparation method mainly comprises that: a hydrolysis assistant is added, and hair is hydrolyzed by a multi-step hydrolysis method to improve the hydrolysis yield of the arginine; after the hydrolysis of the arginine, multi-step refinement and neutralization method is avoided and a one-step refinement, neutralization and decolorization method is applied to purify the arginine product quickly and accurately; after the extraction of the arginine product, a 80 DEG C multi-pass drying process is avoided, and a 180 DEG C one-step continuous feeding and discharging process is adopted to dry the product so as to save energy and improve production efficiency; and the dried product is detected, packaged and put in storage. The preparation method has the advantages of advanced processes, simple and convenient operation, and high service efficiency of raw materials; and the prepared arginine has the advantages of high purity, good service performance, and capacity of being widely used in the industries such as medicament, food, farm chemical and the like.
