Objective:To investigate feasibility of vacuum belt drying technology on pilot-scale production of Shensong Yangxin capsules. Method:Under the same conditions of extraction and concentration
regarding yielf of powder
angle of repose
bulk density
percentage of moisture and contents of effective ingredients as indicators to investigate difference of vacuum belt drying process and spray drying technology for preparing Shensong Yangxin capsules. Result:In samples of vacuum belt drying and spray drying
yield of powder were 23.51%
22.35%
angle of repose were 30.3
32.3°
bulk density were 0.65
0.55 g·cm-3
total drying time were 4.47
7.20 h
percentage of moisture in 72 h were 20.7% and 28.6%
concentrations of paeoniflorin and berberine hydrochloride were 0.36% and 0.75%
respectively. Conclusion:Vacuum belt drying technology was highly feasible on pilot-scale production of Shensong Yangxin capsules with good quality products and high production efficiency.
