对热风干燥和冷冻干燥处理香草兰样品的干燥效果进行比较，结果表明热风干燥的干燥速率随温度的增加而增加，冷冻干燥的干燥速率介于40和50℃热风干燥的速率之间。电子鼻分析结果表明，与40、50和60℃热风干燥相比，相同干燥时间条件下，冷冻干燥能更好的保留香草兰原有风味，同时冷冻干燥处理的香草兰样品具有更强的香气强度。

Desiccative effects of hot-air drying and vacuum freeze-drying for vanilla were compared in this research. The results showed that drying rate of hot-air drying increased with the increasing drying temperature, and the rate of vacuum freeze-drying is between the rates of hot-air drying at 40℃and 50℃. E-nose analysis revealed that, compared with hot-air drying at 40℃, 50℃and 60℃, the drying vanilla treated by vacuum freeze-drying at the same drying time can retain its original flavor and give higher odor intensity.
