This utility model proposes a dehumidification and
aroma preservation device for tobacco leaves, including a
drying device, a conveying device, and a dehumidification and
aroma preservation device. A
drying chamber is formed within the
drying device, and the conveying device is located within the drying chamber for conveying tobacco leaves. A first partition is provided within the drying chamber to divide it into a drying zone and a rehumidification zone. The dehumidification and
aroma preservation device includes a humid hot air
exhaust pipe, a hot
air recovery pipe, a
water vapor recovery pipe, and a
water vapor separation chamber. The air inlet of the humid hot air
exhaust pipe is connected to the drying zone. The recycling of hot air and
water vapor avoids the loss of both, and because the aroma of the tobacco leaves is lost to the exhaust hot air and water vapor during the
roasting process, the lost aroma is reabsorbed and returned to the tobacco leaves, thus preserving the aroma.
