摘要：
Adsorption drying curves were measured with a low-temperature adsorption drying apparatus and drying kinetics of lavender was investigated. Effects of adsorption drying conditions on the contents of total flavonoid, luteolin and apigenin in dried lavender were studied. The preferred drying conditions were optimized by orthogonal experimental design. The results show that adsorption drying rates of lavender increase rapidly by reducing relative humidity and improving drying temperature/space velocity of drying medium. Relative humidity is a key factor to total flavonoid contents, while drying temperature is a sensitive factor to luteolin contents. The suitable drying process conditions are: drying temperature of 30℃, average relative humidity of 16% and space velocity of 905 h-1. The content of total flavonoids under the optimized conditions is 2.673% and the contents of luteolin and apigenin are 0.976% and 0.0245% in dried lavender, respectively. Midilli-Kucuk mathematical model can well fit the adsorption drying curves. The dynamic equation for lavender adsorption drying process is: WR=0.9834exp(-5.484×10-4×t1.46)-6.2934t. © 2017, Editorial Board of “Journal of Chemical Engineering of Chinese Universities”.
