摘要
目的 优化金银花浸膏的真空带式干燥工艺.方法 将单因素试验和响应面试验法结合,确定考察金银花浸膏的相对密度、第 2 段加热温度、履带速率和布料速度 4 个影响因素,以金银花干浸膏的水分和绿原酸转移率的综合评分作为考察指标,对金银花浸膏的真空带式干燥工艺参数进行优化.结果 最优化工艺参数为第2 段加热温度为 90℃、浸膏相对密度为 1.27、履带速率 110 mm/min,布料速度为 1.6 L/h.结论 所得工艺耗时短、效率高,工艺稳定,可操作性强,为金银花工业化生产提供了参考.
Abstract
Objective To optimize of vacuum belt drying process for Lonicerae Japonicae Flos extract.Methods Single factor test combined with response surface tests were used.Four influencing factors as relative density of extract,two-stage heating temperature,track speed,and distribution speed were confirmed,and the comprehensive score of moisture content and chlorogenic acid transfer rate was used as the evaluation index to optimize of vacuum belt drying process.Results The optimized process parameters were as following:the two-stage heating temperature was 90℃,the relative extract density was 1.27,the track speed was 110 mm/min,and the distribution speed was 1.6 L/h.Conclusion The obtained process has short time consumption,high efficiency,stable process,and strong operability,providing a reference for the industrial production of Lonicerae Japonicae Flos.
