The invention discloses a method for curing tobacco leaves, and relates to the technical field of curing. The method comprises the steps that in the yellowing earlier stage, the temperature of a dry bulb rises to 31.5 DEG C to 32.5 DEGC at the speed of 0.8-1.2 DEG C / h, the temperature of a wet bulb is kept between 29.5 DEG C and 30.5 DEG C, the temperature of the wet bulb is stabilized for 13.5 hours to 14.5 hours, and the tips of the tobacco leaves are yellowed; in the yellowing later period, the temperature of the dry bulb rises to 38.5 DEG C to 39.5 DEG C at the speed of 1.8-2.2 DEG C / three hours, the temperature of the wet bulb is kept between 34.5 DEG C and 35.5 DEG C, the temperature of the wet bulb is stabilized for 19.5 hours to 20.5 hours, and the tobacco leaves are yellowed; in the color fixing earlier period, the temperature of the dry bulb rises to 45.5 DEG C to 46.5 DEG C at the speed of 0.8-1.2 DEG C / three hours, and the temperature of the wet bulb is kept between 36 DEG C and 37 DEG C and is stabilized for 19.5 hours to 20.5 hours; in the color fixing later period, the temperature of the dry bulb rises to 54.5 DEG C to 55.5 DEGC at the speed of 0.8-1.2 DEG C / two hours, the temperature of the wet bulb is kept between 37 DEG C and 38 DEG C, and stabilized for 11.5 hours to 12.5 hours, and the tobacco leaves are dried; in the killing-out period, the temperature of the dry bulb rises to 66.5 DEG C to 67.5 DEG C at the speed of 0.8-12 DEG C / h, and the temperature of the wet bulb is kept between 38.5 DEG C and 39.5 DEG C and is stabilized until the tobacco leaves in an overall furnace are baked dry. The curing quality of the tobacco leaves can be improved.
Description
technical field [0001] The invention relates to the technical field of roasting, in particular to a method for roasting tobacco leaves. Background technique [0002] At present, the popularized K326 tobacco leaf curing process is a three-stage curing process, including the following three stages: 1. The yellowing stage. After ignition, the temperature of the curing room is raised to 34-38°C at a rate of 1°C per hour. , keep the wet bulb temperature 1-2.5°C lower than the dry bulb temperature, until more than 80% of the tobacco leaves in the bottom shed turn 80% yellow; then, raise the temperature of the barn to 40-42°C at a rate of 1°C every 4 hours , keep the wet bulb temperature at 36-37°C to make the tobacco leaves turn yellow and soft. 2. In the color-fixing stage, raise the temperature in the oven to 54-55°C at an average rate of 1°C in 2-3 hours, and slowly increase the wet bulb temperature and keep it between 37-40°C for a long enough time. time, so that the back of...
