Embodiment 1

[0036] A method for curing tobacco leaves of a flue-cured tobacco variety Yueyan 97. The Yueyan 97 is obtained by planting bovine liver soil, and the leaf age in the middle part is 104 days. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0037] Yellowing period:

[0038] (1) Fire temperature control: raise the temperature in the barn to 36.2°C at a rate of 1°C / 3h, control the wet bulb temperature to 32.5°C, and stabilize the temperature for 2h; the frequency of the motor changes to 30Hz, and the speed is 500r / min.

[0039] (2) Initial stage of yellowing: Raise the temperature in the barn to 37.2°C at a rate of 0.1°C / h, control the wet bulb temperature to 35.0°C, and stabilize the temperature for 30 hours; the frequency of the motor changes to 35Hz, and the speed is 720r / min.

[0040] (3) Middle stage of yellowing: Raise the temperature in the barn to 38.2°C at a rate of 0.1°C / h, control the wet bulb temperature to 3...

Embodiment 2

[0051] A method for roasting tobacco leaves of flue-cured tobacco variety Yueyan 97. Yueyan 97 is Yueyan 97 planted with bovine liver soil, and the age of the lower tobacco leaves of Yueyan 97 is 55 days during baking. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0052] Yellowing period:

[0053] (1) Fire temperature control: Raise the temperature in the barn to 36.4°C at a rate of 1°C / 3h, control the wet bulb temperature to 32.7°C, and stabilize the temperature for 2h; the frequency of the motor changes to 32Hz, and the speed is 480r / min.

[0054] (2) Initial stage of yellowing: Raise the temperature in the barn to 37.4°C at a rate of 0.1°C / h, control the wet bulb temperature to 34.8°C, and stabilize the temperature for 34 hours; the frequency of the motor changes to 37Hz, and the speed is 700r / min.

[0055] (3) In the middle stage of yellowing: raise the temperature in the barn to 38.4°C at a rate of 0.1°C / h, co...

Embodiment 3

[0066] A method for roasting tobacco leaves of flue-cured tobacco variety Yueyan 97. Yueyan 97 is Yueyan 97 planted with bovine liver soil, and the age of the upper tobacco leaves of Yueyan 97 is 115 days during baking. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0067] Yellowing period:

[0068] (1) Fire temperature control: Raise the temperature in the barn to 36.0°C at a rate of 1°C / 3h, control the wet bulb temperature to 32.3°C, and stabilize the temperature for 2h; the frequency of the motor changes to 28Hz, and the speed is 520r / min.

[0069] (2) Initial stage of yellowing: Raise the temperature in the barn to 37.0°C at a rate of 0.1°C / h, control the wet bulb temperature to 34.8°C, and keep the temperature stable for 28 hours; the frequency of the motor changes to 33Hz, and the speed is 740r / min.

[0070] (3) In the middle stage of yellowing: raise the temperature in the barn to 38.0°C at a rate of 0.1°C / h,...

Abstract

The invention belongs to the technical field of tobacco processing, and in particular relates to a method for curing Guangdong tobacco 97 leaves in flue-cured tobacco varieties. The method disclosed by the invention comprises the following steps: planting to obtain lower tobacco leaves, middle tobacco leaves and upper tobacco leaves of Guangdong tobacco 97 in bovine liver soil, separately curing in different curing barns, and slowly raising the temperature in the tobacco leaf yellowing period in the curing barns, wherein circulating fans used at different curing phases of the yellowing stage, leaf-drying stage and stem drying stage are subjected to frequency conversion control, and the whole curing phase is divided into ten sub-stages; raising the temperature at a low speed during the yellowing period, and controlling the temperature of the yellowing period to 38.5 DEG C or lower; stabilizing the temperature and prolonging the medium / high-temperature yellowing period by 12 hours, and stabilizing the temperature and prolonging the middle and later leaf-drying stage by 12 hours; and finally curing to obtain the Guangdong tobacco 97. The Guangdong tobacco 97 is superior in appearance quality, intrinsic chemical compositions of the tobacco leaves can be coordinated, the sensory evaluation quality of the tobacco leaves is improved, and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for curing tobacco leaves of a flue-cured tobacco variety Yueyan 97. Background technique [0002] Yueyan 97 (formerly MS96-7) is a new hybrid flue-cured tobacco variety of the first generation bred with the MS9207 line as the female parent and the flue-cured tobacco variety Yueyan 96 as the male parent. It was approved by the National Tobacco Variety Approval Committee in March 2009. The plant of this variety grows neatly, with strong growth potential, cylindrical plant shape, uniform leaf setting, reasonable population structure, stable genetic traits, uniform leaf thickness, good layered yellowing, easy to bake; black shank resistance, moderate resistance-anti-blue Blight, moderate sensitivity to CMV, TMV, red spot disease sensitivity, high sensitivity to PVY, and tolerance to fertilizer and water. It is suitable for planting in southern my cou...
