Embodiment 1

[0037] A method for curing tobacco leaves of flue-cured tobacco variety Yueyan 98. Yueyan 98 is obtained by planting purple soil for Yueyan 98, 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.

[0038] Yellowing period:

[0039] (1) Fire temperature control: raise the temperature in the barn to 32.5°C at a rate of 1°C / 3h, control the wet bulb temperature to 32.5°C, and stabilize the temperature for 2h; the motor frequency changes to 30Hz, and the speed is 500r / min.

[0040] (2) Initial stage of yellowing: Raise the temperature in the barn to 35.0°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.

[0041] (3) Middle stage of yellowing: Raise the temperature in the barn to 36.5°C at a rate of 0.1°C / h, control the wet bulb temperature to 36.1°C, ...

Embodiment 2

[0052] A method for roasting tobacco leaves of a variety of flue-cured tobacco, Yueyan 98. Yueyan 98 is Yueyan 98 planted in purple soil, and the age of the lower tobacco leaves of the said Yueyan 98 is 55 days. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0053] Yellowing period:

[0054] (1) Fire temperature control: Raise the temperature in the barn to 32.7°C at a rate of 1°C / 3h, control the wet bulb temperature to 32.7°C, and stabilize the temperature for 2h; the motor frequency changes to 32Hz, and the speed is 480r / min.

[0055] (2) Initial stage of yellowing: Raise the temperature in the barn to 35.2°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.

[0056] (3) Middle stage of yellowing: Raise the temperature in the barn to 36.7°C at a rate of 0.1°C / h, control the wet bulb te...

Embodiment 3

[0067] A method for roasting tobacco leaves of flue-cured tobacco variety Yueyan 98. Yueyan 98 is Yueyan 98 planted in purple soil, and the age of the upper tobacco leaf of Yueyan 98 is 115 days during baking. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0068] Yellowing period:

[0069] (1) Fire temperature control: Raise the temperature in the barn to 32.3°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.

[0070] (2) Initial stage of yellowing: Raise the temperature in the barn to 34.8°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.

[0071] (3) Middle stage of yellowing: Raise the temperature in the barn to 36.3°C at a rate of 0.1°C / h, control the wet ...

Abstract

The invention belongs to the technical field of tobacco processing, and particularly relates to a flue-curing method for flue-cured tobacco Guangdong 98 tobacco leaves. The method comprises the stepsthat purple soil is planted to obtain lower tobacco leaves, middle tobacco leaves and upper tobacco leaves of Guangdong 98 to be flue-cured in different curing barns separately, the temperature is increased slowly in the tobacco leaf yellowing period inside the curing barns, frequency conversion control is performed on a circulating fan adopted in different flue-curing stages of the yellowing period, the fixation period and the stem-drying period, and the whole flue-curing stage is divided into ten small stages; meanwhile, the temperature is increased at low speed in the yellowing period, andthe temperature of the yellowing period is controlled to be 38.5 DEG C or below; the high and medium temperature yellowing steady temperature period is prolonged by 12 h, and the fixation middle and later period steady temperature period is prolonged by 12 h; finally, the Guangdong 98 obtained after flue-curing is superior in appearance and quality, chemical components inside the tobacco leaves can be coordinated, the tobacco leaf sensory evaluation quality is improved, and 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 98. Background technique [0002] The new variety Yueyan 98 was obtained by crossing Coker206 as the female parent and K326 as the male parent to obtain F1, which was obtained through selfing, pedigree selection, backcross aggregation, and pedigree selection again. This variety grows neatly in the field, has strong growth potential, good plant type, wide adaptability, and stable genetic traits; it has good maturity, loose leaf structure, moderate leaf thickness, and rich oil content; the internal chemical components of the tobacco leaves are coordinated, and the aroma is good. Good amount of aroma. [0003] The quality and style characteristics of tobacco leaves are gradually formed during the growth and development of tobacco leaves. It is reflected through the modulation technology...
