Outline
To optimize the spray drying process parameters of Yixintai compound concentrate.
The G1-entropy weight method was used to calculate the comprehensive score of the contents of astragaloside IV, salvianolic acid B and hydroxysafflor yellow A and the extraction rate, and the comprehensive score was used as the evaluation index. The effects of dextrin dosage, relative density of liquid medicine, peristaltic speed, air inlet temperature and air volume flow on spray drying process were investigated by single factor experiment. The spray drying parameters of Yixintai compound concentrate were optimized by Box-Behnken response surface design and BP neural network.
The optimum parameters of spray drying technology were as follows: relative density of liquid medicine 1.12, dextrin ratio 20%, air inlet temperature 150 degrees, air flow 35 m3·h-1 and peristaltic pump speed 15 r·min-1.
The optimized spray drying process of Yixintai compound concentrate is stable and feasible.
