Description
Technical Field
The invention relates to a method for baking autumn tobaccos in a high-altitude tobacco area.
Background
In a high-altitude tobacco area (a tobacco area with an altitude of more than 1000 m), the temperature is reduced more quickly after autumn, the temperature is lower, on one hand, the influence on the maturity of tobacco leaves is larger, the tobacco leaves are matured more slowly, the maturity is lower, the flue-curing property of the tobacco leaves is poor, and the quality of fresh tobacco leaves is poor; on the other hand, the temperature is more quickly reduced and lower, so that the influence on the temperature in the curing barn is greater, and the temperature stabilization and temperature rise operation are more difficult.
The autumn tobacco is usually transplanted too late due to late harvest of previous crops and the like, so that the growth period is delayed and the autumn tobacco is generated. The average air temperature suddenly drops in the autumn, the air humidity is reduced, the temperature difference between day and night is relatively large, and the following characteristics are generated: the tobacco leaves are thick and solid, coarse in tissue, compact in structure, low in water content, full in inclusion and thickened in cuticle.
Disclosure of Invention
The invention aims to provide a method for baking autumn tobaccos in a high-altitude tobacco area, which aims to solve the quality problems of ash hanging, stiffness, thicker identity, compact structure, poor looseness and the like of baked tobacco leaves in the existing baking technology of the autumn tobaccos at high altitude, and the problems of low tobacco leaf grade, poor tobacco grower income and poor industrial availability. The technical effects that can be produced by the preferred technical scheme in the technical schemes provided by the invention are described in detail in the following.
In order to achieve the purpose, the invention provides the following technical scheme:
the invention provides a method for baking autumn tobaccos in a high-altitude tobacco area, which comprises the following steps:
(1) low temperature heating sweating
Igniting and heating, namely slowly raising the temperature of the baked tobacco leaves to 32-33 ℃ until the tips of the tobacco leaves begin to turn yellow;
(2) color change of temperature-stabilizing blade
Continuously raising the temperature of the baked tobacco leaves to 41-42 ℃ on the basis of the step (1) until the yellowing degree of the tobacco leaves reaches 90-95%;
(3) moderate temperature blade drying
Continuously raising the temperature of the baked tobacco leaves to 54-55 ℃ on the basis of the step (2) until the tobacco leaves are dried;
(4) high temperature pulse drying
Continuously raising the temperature of the baked tobacco leaves to 67-68 ℃ on the basis of the step (3) until the main veins of the tobacco leaves are dry;
(5) lower kang with cooling and moisture regaining functions
When the main vein of the tobacco leaves is dry, the fire is immediately stopped, and the tobacco leaves are put into the kang after being naturally dampened.
Further, the steps of rod weaving and cigarette filling are required before the step (1); the weaving rod is formed by weaving 110-120 tobacco leaves into a standard rod with the length of 1.5 m; the tobacco filling is that the tobacco leaves after being woven into rods are uniformly and uniformly filled into a curing barn, and the rod distance is controlled to be 18-22 cm.
Further, the low-temperature heating sweating in the step (1) is to heat the tobacco leaves by ignition after the tobacco leaves are filled, raise the temperature of the dry balls to 32-33 ℃ at a speed of 1-2 ℃ per hour and keep the temperature stable until the tips of the tobacco leaves begin to turn yellow, and then start to perform the step (2) of stabilizing the temperature and changing the color of the leaves.
Furthermore, in the low-temperature heating sweating in the step (1), the air inlet and the air outlet of the curing barn need to be tightly closed during ignition heating.
Further, the color change of the temperature-stabilizing blade in the step (2) comprises a first color change and a second color change;
the first color change is that after the leaf tips of the tobacco leaves begin to turn yellow, the dry bulb temperature is increased to 37-38 ℃ at the temperature rising speed of 0.2-0.8 ℃ per hour, the dry-wet difference is kept to be 2-3 ℃ after the leaf tips are stabilized, and the dry-wet bulb temperature is stabilized, so that the yellowing degree of the tobacco leaves reaches 35-45%;
and the second color change is that after the yellowing degree of the tobacco leaves reaches 35-45%, the dry bulb temperature is increased to 41-42 ℃ at the temperature rising speed of 0.5-1.5 ℃ per hour, the wet bulb temperature is kept at 36-38 ℃, and the temperature and the humidity are stabilized until the yellowing degree of the tobacco leaves reaches 90-95%.
Further, during the first color change, the color should be artificially moisturized when the difference between dry and wet is more than 3 ℃.
Further, the drying of the medium-temperature leaves in the step (4) comprises three stages of complete color change, tobacco stem color change and tobacco leaf drying;
the complete color change stage is that after the yellowing degree of the tobacco leaves reaches 90-95%, the dry bulb temperature is increased to 46-48 ℃ at the temperature rising speed of 0.2-0.8 ℃ per hour, and the wet bulb temperature is kept at 37-38 ℃ and kept stable until all the tobacco leaves are completely yellow;
in the tobacco rib color changing stage, after all tobacco leaves are observed to be totally yellow, the dry bulb temperature is increased to 49-51 ℃ at the temperature rising speed of 0.5-1.5 ℃ per hour, and the wet bulb temperature is kept at 39-41 ℃ and kept stable until the tobacco ribs are yellow and the tobacco leaves are semi-wound;
the tobacco leaf drying stage is that after the tobacco stem turns yellow and the tobacco leaf semi-winding drum is observed, the dry bulb temperature is raised to 54-55 ℃ at the temperature raising speed of 0.5-1.5 ℃ per hour and is kept stable, and the wet bulb temperature is kept at 40-41 ℃ until the leaves of the full kang are dried.
Further, the step (4) of drying the main vein at high temperature is that after the drying of the leaves of the full kang is observed, the dry bulb temperature is increased to 67-68 ℃ at the speed of 0.5-1.5 ℃ per hour and is kept stable, and the wet bulb temperature is kept at 41-42 ℃ until the main vein of the leaves of the full kang is completely dried.
Further, the temperature reduction and moisture regaining of the lower kang in the step (5) is to immediately stop fire after the main veins of the leaves of the whole kang are observed to be completely dried, so that the temperature of a dry bulb in a curing barn is naturally reduced to enable tobacco leaves to be naturally moisturized, and when the moisture content of the tobacco leaves reaches 14-16%, the tobacco leaves are put into the lower kang to prepare for primary division operation.
Further, the moisture content of the tobacco leaves is judged through a sense organ, and when the tobacco leaves are not broken when being held by hands and are not laid upright, the moisture content of the tobacco leaves can be judged to be 14-16%.
Based on the technical scheme, the embodiment of the invention can at least produce the following technical effects:
(1) the method for baking the tobacco leaves in the high-altitude tobacco area after autumn provided by the invention has scientific and reasonable temperature and humidity, and is particularly suitable for the tobacco leaves in the high-altitude tobacco area after autumn, so that the phenomena of ash hanging and stiffness of the baked tobacco leaves are not easy to occur.
(2) According to the method for baking the autumn tobaccos in the high-altitude tobacco area, the temperature is slowly increased during baking, so that the tobacco leaves are fully baked, the temperature is prevented from being suddenly increased and decreased, and the problems of thick identity, compact structure and poor looseness of the baked tobacco leaves are solved.
(3) The baking method of the autumn tobacco in the high-altitude tobacco zone provided by the invention is operated according to a five-period eight-step baking process by taking slow temperature rise, slow yellowing, moisture control and color stabilization as ideas, the grade of the baked tobacco is higher, the income of tobacco growers is improved, and the industrial availability is increased.
