Embodiment 1

[0037] The invention discloses a method for curing tobacco leaves of the flue-cured tobacco variety Xiangyan No. 3. The Xiangyan No. 3 is planted in sandy soil, and the leaf age in the middle part is 75 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 36.0°C at a rate of 1°C / 3h, control the wet bulb temperature to 35.0°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 37.1°C at a rate of 0.1°C / h, control the wet bulb temperature to 35.3°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 38.2°C at a rate of 0.1°C / h, control the wet bulb tempera...

Embodiment 2

[0052] A method for roasting tobacco leaves of flue-cured tobacco variety Xiangyan No. 3. Xiangyan No. 3 is planted in sandy soil, and the age of the lower tobacco leaves of Xiangyan No. 3 is 65 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 36.2°C at a rate of 1°C / 3h, control the wet bulb temperature to 28.2°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 37.2°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.

[0056] (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 wet bulb temperature t...

Embodiment 3

[0067] A method for roasting tobacco leaves of a flue-cured tobacco variety, Xiangyan No. 3. Xiangyan No. 3 is planted in sandy soil, and the upper part of the tobacco leaf of Xiangyan No. 3 is 85 days old during curing. 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 35.8°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.

[0070] (2) Initial stage of yellowing: Raise the temperature in the barn to 36.9°C at a rate of 0.1°C / h, control the wet bulb temperature to 35.3°C, and stabilize the temperature 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 37.8°C at a rate of 0.1°C / h, control...

Abstract

The invention belongs to the technical field of tobacco processing and particularly relates to a method for baking flue-cured tobacco variety Xiangyan No. 3 tobacco. According to the method, lower tobacco, middle tobacco and upper tobacco of Xiangyan No. 3 obtained by planting in sandy soil are separated and baked in different baking chambers, the temperatures during the tobacco yellowing period in the baking chambers rise slowly, circulating fans used at different baking periods at a yellowing period, a color fixation period and a dry rib period are regulated in a frequency conversion mode, and the whole baking period is divided into ten small periods; the temperature rises at a low speed during the yellowing period, and the temperature at the yellowing period is controlled below 39 DEG C; the medium-high temperature yellowing constant temperature is prolonged by 12 hours, and the color fixation middle and later period constant temperature is prolonged by 12 hours; finally is not only the baked Xiangyan No. 3 superior in appearance and quality, but also internal chemical ingredients of the tobacco can be coordinated, the sensory evaluation quality of the tobacco 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 Xiangyan No. 3. Background technique [0002] Xiangyan No. 3 is resistant to black shank, moderately resistant to root-knot nematode incognita, moderately resistant to bacterial wilt, and moderately susceptible to common mosaic disease. The field growth period is about 122 days, the natural plant height is 138.6 cm, the topping plant height is 108.1 cm, the number of natural leaves is 24-28 pieces, the number of effective leaves is 19-20 pieces, the stem circumference is 9.0 cm, the pitch is 5.1 cm, and the waist leaves are elliptical Shape, 74.1 cm long, 29.4 cm wide, green leaf, red flower, wrinkled leaf surface, acuminate leaf tip, medium main vein, moderate leaf thickness, loose leaf tissue. [0003] The quality and style characteristics of tobacco leaves are gradually formed during t...
