[0023] Example 1: For Yunyan 87 tobacco leaves from a certain producing area in Hubei Province, the tobacco leaf pre-withering roasting process in the dense curing barn is used for baking. The specific steps include:
[0024] (1) During the tobacco leaf roasting season, the collected fresh Yunyan 87 tobacco leaves are passed through braided rods or tobacco clips, and then pre-withered on a shaded tobacco rack, causing the lower tobacco leaves to lose 14.6% of water. The tobacco leaves are obviously soft; the middle tobacco leaves lose 12.1% of water and the tobacco leaves are soft; the upper tobacco leaves lose 10.8% of water, and the tobacco leaves are Microsoft;
[0025] (2) The Yunyan 87 tobacco leaves that meet the dehydration requirements after the pre-withering treatment in step 1 are moved into the intensive curing barn, and they will be ignited after they are installed. The temperature rise rate is increased from 1°C to 38°C per hour and then the temperature is stabilized. ...
Example Embodiment
[0029] Example 2 For the central tobacco leaves of Yunyan 87 from a certain place in Hubei Province, the following two baking processes are used: T1 is a three-stage baking (the existing conventional process), and T2 is baked by a pre-withering intensive baking process (this The process described in the invention), the energy consumption statistics of the curing, the economic properties, appearance quality, chemical composition, and sensory quality of the cured tobacco leaves are compared. The results are shown in Table 1-5.
