Abstract: Objective To optimize the vacuum belt drying process for Lonicerae Japonicae Flos extract using orthogonal test. Methods The contents of chlorogenic acid and extract yield were taken as indexes, as well as heating plate temperature, track speed, and feeding speed as factors, the best belt drying process of Lonicerae Japonicae Flos extract was optimized using L9(34) orthogonal test. Results The optimal vacuum belt drying process conditions were as follows: heating plate temperature of 60 ℃, track speed of 175 mm/min, and feeding speed of 18 L/h. Conclusion The chlorogenic acid content is high and the yield is stable, which is suitable for mass production of Lonicerae Japonicae Flos extract using vacuum belt drying process.
