[0041] (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.

[0042] (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, and stabil...

Embodiment 2

[0053] A method for curing tobacco leaves of a flue-cured tobacco variety H892. H892 is obtained by planting in sandy soil, and the age of the lower tobacco leaves of the H892 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 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.

[0056] (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.

[0057] (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 tempe...

Embodiment 3

[0068] A method for curing tobacco leaves of flue-cured tobacco variety H892. H892 is obtained by planting in sandy soil. The age of the upper tobacco leaves of H892 is 115 days 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 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.

[0072] (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 tempe...

Abstract

The invention belongs to the technical field of tobacco processing, and particularly relates to a baking method of flue-cured tobacco variety H892 tobacco leaves. The method comprises the following steps: separately baking lower tobacco leaves, middle tobacco leaves and upper tobacco leaves of the flue-cured tobacco variety H892 planted in sandy soil in different baking rooms, slowly increasing the temperature in the baking room in the yellowing period of the tobacco leaves, controlling and regulating a circulating fan used at different baking periods such as a yellowing period, a color fixing period and a stem drying period in a variable frequency manner, wherein the whole baking period is divided into ten phases; slowly increasing the temperature in the yellowing period, and controlling the temperature in the yellowing period at 39.2 DEG C or lower; prolonging the high-medium-temperature yellowing period by 12 hours at a constant temperature, and prolonging the color-fixing medium-later period by 12 hours at the constant temperature. Not only can the finally baked H892 be good in appearance quality, but also chemical components in the tobacco leaves can be coordinated, the impression and smoking quality of the tobacco leaves can be improved, and the economic benefit can be 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 H892. Background technique [0002] H892 is a hybrid flue-cured tobacco variety with relatively short plants but high aroma characteristics. [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. The fundamental purpose of tobacco leaf curing is to reveal and maximize the quality potential of tobacco leaves formed and accumulated in the agronomic process. . [0004] Intensive curing barn is a new type of flue-cured tobacco curing equipment widely used in tobacco leaf producing areas in recent years, and it is a major technical reform in the tobacco leaf curing process. The intensive curing barn not only has brighter and more uniform color of the tobacco leave...
