搁板可加热，这样可使升华速度加快，减少干燥周期。
The baggage shelf may heat up, speeding up the sublimation and reducing the dry cycle.
物料的干燥周期一般只有10 - 300秒，在适合于热敏性物料。
The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials.
这样既缩短了干燥周期又提高了干燥质量，同时也提高了干燥窑的生产效率。
The test results showed that the comprehensive vapor drying technology would not only shorten drying time, but also improve drying quality, as well as increase efficiency of produce.
