Method for preparing arginine ketoglutaric acid by spraying method

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 productio
