Description

Heating and humidifying device for tobacco leaves Technical Field The utility model relates to the technical field of tobacco leaf heating and humidifying, in particular to a heating and humidifying device for tobacco leaves. Background The period from the raw tobacco warehouse entry to the finished product warehouse exit is longer. In the process, the temporarily stored tobacco leaves are seriously scattered before and after sorting, so that the tobacco leaf breakage rate is high in the sorting and leaf spreading processes, and in order to reduce the breakage rate of the tobacco leaves and improve the leaf yield of finished tobacco leaves, the tobacco leaves need to be heated and humidified before sorting or threshing and redrying. The temperature difference between the tobacco leaf and the hot air is the potential difference of sensible heat transfer, and the difference between the partial pressure of water mist in the hot air and the partial pressure of water vapor on the surface of the tobacco leaf is the potential difference of water mist transfer from the flue gas to the solution. In the process of absorbing moisture of tobacco leaves, on one hand, water vapor in the water mist transfers mass to the tobacco leaves, on the other hand, sensible heat in hot air transfers heat to the tobacco leaves, and the temperature of the tobacco leaves is increased to change the partial pressure of the water vapor on the surface of the tobacco leaves so as to influence the speed of absorbing the water mist, so that the effects of the heat transfer potential difference and the mass transfer potential difference of the tobacco leaves on the water mist absorbing process on the heat and mass transfer process are mutually influenced and coupled together.
