正交试验法优选延胡索浸膏的喷雾干燥工艺

摘要

目的 研究延胡索浸膏的喷雾干燥工艺.方法 采用L9(34)正交设计法,以喷雾粉出粉量、延胡索乙素含量和水分为检测指标,考察进风口温度、出风口温度、浸膏相对密度对延胡索浸膏喷雾干燥的影响,优化喷雾干燥技术.结果 优选喷雾干燥工艺为:进风口温度180℃,出风口温度80℃,浸膏相对密度1.15.结论 该工艺合理、可行,为工业化生产提供了试验性基础依据.%Objective To investigate the spraying dry process of Yanhusuo Extract. Methods The effects of inlet temperature, outlet temperature and relative density of the extract on the spraying dry process of Yanhusuo Extract were inspected by L9 (34) orthogonal experiment with the powder amount, tetrahydropalmatine content, and moisture content were taken as the indexes, based on this, the spraying dry technology was optimized. Results The optimum technology conditions were conformed for inlet temperature as 180℃, outlet temperature as 80℃ and specific gravity as 1.15. Conclusion This optimized spraying dry process is rational, feasible and provides experimental basic data for industrial production.
