Embodiment 1

[0038]The invention discloses a method for curing tobacco leaves of flue-cured tobacco variety Zhongyan 100. Zhongyan 100 is obtained by planting sandy soil for Zhongyan 100, and the leaf age of the central tobacco is 104 days. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0039] Yellowing period:

[0040] (1) Fire temperature control: raise the temperature in the barn to 34.5°C at a rate of 1°C / 3h, control the wet bulb temperature to 34.5°C, and stabilize the temperature for 2h; the motor frequency changes to 30Hz, and the speed is 500r / min.

[0041] (2) Initial stage of yellowing: Raise the temperature in the barn to 35.1°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 motor frequency changes to 35Hz, and the speed is 720r / min.

[0042] (3) Middle stage of yellowing: Raise the temperature in the barn to 38.0°C at a rate of 0.1°C / h, control the we...

Embodiment 2

[0053] A method for curing tobacco leaves of flue-cured tobacco variety Zhongyan 100. Zhongyan 100 is planted in sandy soil, and the age of the lower tobacco leaves of Zhongyan 100 is 55 days during curing. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0054] Yellowing period:

[0055] (1) Fire temperature control: Raise the temperature in the barn to 34.2°C at a rate of 1°C / 3h, control the wet bulb temperature to 34.2°C, and stabilize the temperature for 2h; the frequency of the motor changes to 32Hz, and the speed is 480r / min.

[0056] (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 34.9°C, and stabilize the temperature for 34 hours; the frequency of the motor changes to 37Hz, and the speed is 700r / min.

[0057] (3) Middle stage of yellowing: Raise the temperature in the barn to 37.8°C at a rate of 0.1°C / h, control the wet bulb ...

Embodiment 3

[0068] A method for curing tobacco leaves of a variety of flue-cured tobacco, China Tobacco 100. China Tobacco 100 is planted in sandy soil, and the upper tobacco leaves of China Tobacco 100 are 115 days old during curing. The roasting process includes the yellowing period, the color fixing period and the gluten-drying period.

[0069] Yellowing period:

[0070] (1) Fire temperature control: Raise the temperature in the barn to 34.8°C at a rate of 1°C / 3h, control the wet bulb temperature to 30.2°C, and stabilize the temperature for 2h; the frequency of the motor changes to 28Hz, and the speed is 520r / min.

[0071] (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 35.2°C, and stabilize the temperature for 28 hours; the frequency of the motor changes to 33Hz, and the speed is 740r / min.

[0072] (3) In the middle stage of yellowing: raise the temperature in the barn to 37.8°C at a rate of 0.1°C / h...

Abstract

The invention belongs to the technical field of tobacco processing, and particularly relates to a flue-curing method for flue-cured tobacco China 100 tobacco leaves. The method comprises the steps that sand soil is planted to obtain lower tobacco leaves, middle tobacco leaves and upper tobacco leaves of China 100 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, thefixation 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, and the temperature of the yellowing period is controlled to be 39 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 China 100 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 the flue-cured tobacco variety Zhongyan 100. Background technique [0002] China Tobacco 100 is the China Tobacco Genetics and Breeding Research (Northern) Center, which focuses on high-quality disease resistance. The high-quality variety NC82 is used as the central parent to cross with the multi-resistant complementary parent 9201. After 5 generations of backcrossing with NC82, the pedigree method is used for orientation. The high-quality multi-resistance flue-cured tobacco new variety selected and bred was approved by the National Tobacco Variety Approval Committee in December 2002. China Tobacco 100 has a cylindrical plant with about 24 leaves, 20-22 leaves can be harvested, the leaf shape is oval, the leaf surface is slightly wrinkled, the leaf tip is acuminate, the leaf color is green, the waist leaf length is 65.6...
