正交试验法优选黄连浸膏的喷雾干燥工艺

Optimization of Spray Drying Process of Coptidis Rhizoma Extract by Orthogonal Test

摘要:

目的: 优选黄连浸膏的喷雾干燥工艺。 方法: 采用L₉(3⁴)正交设计法,以喷干粉出粉量、小檗碱含量和含水量为指标,考察进风口温度、出风口温度、浸膏比重对黄连浸膏喷雾干燥工艺的影响。 结果: 优选的喷雾干燥工艺为进风口温度180℃,出风口温度80℃,浸膏比重1.15。 结论: 该优选工艺合理、稳定,可为黄连的工业化生产提供实验依据。

Abstract:

Objective:To investigate spray drying process of Coptidis Rhizoma extract. Method: With the amount of spray dry powder,the content of berberine and moisture content as indexes,effect of air inlet temperature,outlet temperature and extract specific gravity on spray drying process of Coptidis Rhizoma extract was investigated by orthogonal test. Result: Optimal spray drying process was:air inlet temperature 180℃,outlet temperature 80℃ and extract specific gravity of 1.15. Conclusion: This optimized process was rational and stable,it could provide experimental basis for industrial production of Coptidis Rhizoma.
