Method for preparing arginine ketoglutaric acid by spraying method

Abstract

The invention relates to the field of arginine ketoglutaric acid preparation processes, in particular to a method for preparing arginine ketoglutaric acid by a spraying method. The method comprises the following steps: 1, starting up for inspection; 2, draining water from the system; 3, air supply testing; 4, adjusting the temperature; 5, adjusting the pressure; 6, spray testing; 7, high-pressurefeeding; 8, detecting the temperature; 9, dehumidifying and refluxing; and 10, centralized material collection. The beneficial effects are that: production is carried out by adding a set pressure spraying mode, the production process is optimized, byproducts are avoided, the production yield is high, production pollution is avoided, all the used raw materials are fermented and produced by themselves, the product yield is high, the product quality is good, and compared with a traditional water reaction recrystallization method, a one-time spraying method is adopted in the production process forproduction, the production process is less in pollution, the yield is higher, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to the field of preparation technology of arginine ketoglutarate, in particular to a method for preparing arginine ketoglutarate by spraying. Background technique [0002] AAKG is an amino acid salt health product that is increasingly sold in the international market. It is mainly used to improve human protein and enhance human physique. At this stage, its production is limited to several large foreign companies such as: Ajinomoto, ADM, Degussa, etc. There are not many manufacturers that can produce in our country. Because of the gap in types and product quality, the French Ruifalan Pharmaceutical Factory has spent more than ten years on the basis of experiments such as pharmacological analysis, toxicological identification, animal liver tissue regeneration, and animal in vivo detoxification. , conducted a series of clinical studies, proving that α-ketoglutaric acid double arginine has a significant curative effect on liver disea...

Problems solved by technology

[0006] The third is the crystallization method. After the solution is mixed, the solution is concentrated or an organic solvent is added to reduce the solubility of AAKG, and AAKG crystals are precipitated. After washing and drying, the AAKG product is obtained. The product prepared by this method has high purity and product quality. Guaranteed, but the process is complicated and the cost is high

[0007] In the first two methods, the preparation process cannot remove the impurities brought in by the raw materials, so higher requirements are placed on the quality control of the product
