Production of food-grade calcium phosphate utilizing thermal phosphoric acid and lime

The importance of feed phosphates in animal husbandry and the state of their production are mentioned in the article. Dicalcium phosphate and tricalcium phosphate production processes in the recirculation mode and tricalcium phosphate in the non-recirculation mode were studied by the interaction of thermal phosphoric acid and lime. In this case, at a concentration of 50.58% of Н3РO4 in Р2O5, its optimal rate was obtained from stoichiometry for dicalcium phosphate as 95%, for tricalcium phosphate as 100%. It fully meets the standard requirements for the quality of two types of nutritional calcium phosphates, at the same time it allows to increase the actual mass of poultry and cattle, plays an important role in dramatically increasing the weight of black cattle, accelerating their digestion process, milk production, and increasing the volume of egg laying in poultry, and also treats diseases such as rickets, osteomalacia, anemia.
