The utility model discloses a heating and humidifying device for tobacco leaves, which comprises an air cabinet, a heating device and a humidifying device, wherein the air cabinet is provided with a
fresh air port and an air outlet; the wet film humidifier is arranged in the air cabinet; the first heating
assembly is arranged in the air cabinet; the second heating
assembly is arranged in the air cabinet, and the first heating
assembly and the second heating assembly are located on the two sides of the wet film humidifier; air passing through the
fresh air opening sequentially passes through the first heating assembly, the wet film humidifier and the second heating assembly and then is exhausted through the air outlet. According to the temperature and
humidity requirements of tobacco leaves, even if the heating
air temperature of the first heating assembly, the passing
humidity of the wet film humidifier and the heating
air temperature of the second heating assembly are adjusted, accurate control over the temperature and
humidity of hot air is achieved, and the heating and humidifying accuracy of the tobacco leaves is improved; by means of heating and humidifying hot wind energy generated by the
tobacco leaf heating and humidifying device, instant loss of chemical components in tobacco leaves is effectively avoided.
