Embodiment 1
[0018] A method for roasting Honghua Dajinyuan variety tobacco leaves in a closed tobacco curing room, the method comprising the following steps: a yellowing period, a color-fixing period and a gluten-drying period;
[0019] Yellowing period: Place the leaves of the Honghua Dajinyuan variety in a closed flue-cured room, and use a dehumidification heat pump to bake them at a rate of 1.5°C / hour to a dry bulb temperature of 34°C and a wet bulb temperature of 32°C , kept for 22 hours, until the top tobacco leaves turned yellow by more than 40%, then raised the dry bulb temperature to 38°C and wet bulb temperature to 35°C at a heating rate of 1°C / hour, and kept for 25 hours; The heating rate is such that the dry bulb temperature reaches 43° C. and the wet bulb temperature reaches 34° C., and keeps for 18 hours until the tobacco leaves turn yellow.
[0020] Color fixation period: after the end of the yellowing period, raise the temperature of the dry bulb to 52℃ and the temperature ...
