The invention discloses a method for determining control parameters of an acid adding process during production of medicinal calcium chloride, belonging to a production process of medicinal calcium chloride. The invention particularly relates to determination of the technical control parameters of the acid adding process during production of medicinal calcium chloride. Through experimental study on process control points such as evaporation termination temperature, evaporation acid adding amount, drying temperature, drying time and the like, the optimal acid adding control parameters for medicinal calcium chloride production are determined. As production is carried out through the determined technological parameters, influences of corrosion and the like on a production device due to the fact that the acid adding amount is too large in the production process are avoided, influences on production efficiency and product quality due to improper control over indexes such as evaporation temperature and time are avo
