摘　　要：目的:采用L9(34)正交试验法优化黄芩提取物的带式干燥工艺。方法:以黄芩苷含量和提取物收率为评价指标,选择加热温度、履带转速、进料流量为考察因素,筛选黄芩提取物的最佳带式干燥工艺。结果:最佳干燥工艺为:加热温度为115℃,进料流量为20L/h,履带转速为160mm/min。结论:带式干燥法干燥黄芩提取物可最大限度地保留黄芩苷成分,收率稳定,适用于大规模工业化生产。Objective： To use L9 （34 ）orthogonal experiment method to optimize scutellaria extract band drying process. Methods： According to the content of baicalin and extract yield as investigation index, selection of heating temperature, track speed, feed flow rate as factors, determine the best belt drying process of scutellaria extract. Results： the best drying process conditions are ： heating plate temperature 115℃, feeding flow rate is 20L/h, track speed is 160mm/min. Conclusion：the method of baicalin contene is high, stable yield, and is suitable for large scale production.
