喷雾干燥条件对复方黄连干粉质量的影响

Effect of Spray Drying Conditions on Quality of Fufang Huanglian Powder

目的:通过实验优选出复方黄连干粉的最佳喷雾干燥制备条件。方法:以复方黄连干粉含水量及盐酸小檗碱损失率为指标,考察不同进风温度,喷速对复方黄连干粉质量的影响。结果:优选出最佳喷雾干燥条件,进风温度170～190℃,喷速3 500 mL.h-1。结论:采用上述喷雾干燥条件制备复方黄连干粉是可行的。

Objective：To optimize spray drying process of Fufang Huanglian powder.Method：By using water content and the loss rate of berberine as parameters,to investigate the effect of different inflow wind temperature and spraying velocity on quality of Fufang Huanglian powder.Result：The best spraying dry conditions were as follows：inflow wind temperature at 170-190 ℃ and spraying velocity at 3 500 mL·h-1.Conclusion：Prepared Fufang Huanglian powder is feasible by the optimum method.
