[0038] Yellowing period:

[0039] (1) Fire temperature control: raise the temperature in the barn to 35.0°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 36.1°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 37.6°C at a rate of 0.1°C / h, control the wet bulb temperature to 36.1°C,...

Embodiment 2

[0052] A method for curing tobacco leaves of flue-cured tobacco variety K326. K326 is obtained by planting purple soil, and the age of the lower tobacco leaves of K326 is 55 days during curing. 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 35.2°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 36.2°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) In the middle stage of yellowing: raise the temperature in the barn to 37.7°C at a rate of 0.1°C / h, control the wet bulb temperature t...

Embodiment 3

[0067] A method for curing tobacco leaves of flue-cured tobacco variety K326. K326 is obtained by planting purple soil, and the age of the upper tobacco leaves of K326 is 115 days 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 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.

[0070] (2) Initial stage of yellowing: Raise the temperature in the barn to 35.8°C at a rate of 0.1°C / h, control the wet bulb temperature to 35.3°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) In the middle stage of yellowing: raise the temperature in the barn to 37.3°C at a rate of 0.1°C / h, control the wet bulb tem...

Abstract

The invention belongs to the technical field of tobacco processing, and particularly relates to a curing method for the flue-cured tobacco variety K326. The curing method includes respectively curing tobacco leaves of the lower portion, the middle portion and the upper portion of the tobacco plant K326 planted in purple soil in different curing barns, slowly rising temperature of the insides of the curing barns at the tobacco leaf yellowing age, carrying out variable-frequency regulation and control of circulating fans used at different curing stages including the yellowing stage, the leaf drying stage and the stem drying stage and particularly dividing the whole curing stage into ten stages; cooling slowly at the yellowing stage with the temperature controlled below 39 DEG C; preserving heat at medium and high temperature for 12 hours and preserving heat at the middle and later periods of the leaf drying stage for 12 hours so as to obtain the flue-cured tobacco variety K326. The flue-cured tobacco variety K326 has high appearance quality, internal chemical components of the tobacco leaves are coordinated, sensory smoking quality of the tobacco leaves is improved, and accordingly economic benefit is 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 flue-cured tobacco variety K326. Background technique [0002] K326 was bred by the Northup King Seed Company of the United States by crossing McNair225 (McNair30×NC95). It was introduced from the United States to Yunnan Province in 1985, and was approved by the Yunnan Provincial Crop Variety Approval Committee as a popular variety in 1988. From 1986 to 1988, he participated in the national regional test of improved varieties of flue-cured tobacco. In 1989, the National Tobacco Variety Approval Committee approved it as a nationally popularized improved variety. K326 is cylindrical or tower-shaped, with a plant height of 110-130cm, a pitch of 4-4.89cm, a stem circumference of 7-8.90cm, a number of 24-26 leaves, and 18-22 leaves can be harvested. The loin leaf is oblong in shape, green in color, with acuminate tip, wavy ...
