Problems solved by technology

The problems existing in K326 baking mainly include: the lower leaves are easy to turn green. The main reasons are that the climatic drought leads to large differences in leaf maturity, tissue stiffness, slow yellowing during the yellowing period, and uneven yellowing, resulting in green leaves after roasting. Dry smoke with yellow bands; blue and yellow smoke in the middle leaves, mainly due to insufficient maturity, insufficient yellowing and unsynchronized water loss; the upper leaves are variegated and ash, mainly due to the variety of the upper leaves. Long roasting time, stiff leaves, more ash and variegation

Embodiment 1

[0028] A. Harvesting: Harvesting the flue-cured tobacco leaves whose tendons turn white, the leaf surface is light yellow, and most of the down hairs fall off;

[0029] B. Furnace loading: put the tobacco leaves collected in step A into the barn, and the smoke density is 42kg / m 3 , fill the smoke to more than 95% of the volume of the barn;

[0030] C. Yellowing: including the early stage of yellowing and the late stage of yellowing. In the early stage of yellowing, the dry bulb temperature is raised from 29°C to 34°C, and the wet bulb temperature is adjusted from 26°C to 33°C at a heating rate of 1°C / 2h. Stabilize the dry and wet bulb temperatures, bake for 47 hours, until the bottom tobacco leaves turn yellow by 1 / 3; then enter the later stage of yellowing, raise the dry bulb temperature to 40°C at a heating rate of 1°C / 2h, and adjust the wet bulb temperature to 35°C, stable dry and wet bulb temperature, baked for 23 hours, until the bottom tobacco leaves are completely yell...

Embodiment 2

[0034] A. Harvesting: Harvesting the flue-cured tobacco leaves whose tendons turn white, the leaf surface is light yellow, and most of the down hairs fall off;

[0035] B. Furnace loading: put the tobacco leaves collected in step A into the barn, and the smoke density is 45kg / m 3 , fill the smoke to more than 95% of the volume of the barn;

[0036] C. Yellowing: including the early stage of yellowing and the late stage of yellowing. In the early stage of yellowing, the dry bulb temperature is raised from 29°C to 36°C, and the wet bulb temperature is adjusted from 27°C to 35°C at a heating rate of 1°C / 1h. Stabilize the dry and wet bulb temperatures, bake for 49 hours, until the bottom tobacco leaves turn yellow by 1 / 3; then enter the later stage of yellowing, raise the dry bulb temperature to 42°C at a heating rate of 1°C / 1h, and adjust the wet bulb temperature to 36°C, stable dry and wet bulb temperature, baked for 25 hours, until the bottom tobacco leaves are completely yell...

Embodiment 3

[0040] A. Harvesting: Harvesting the flue-cured tobacco leaves whose tendons turn white, the leaf surface is light yellow, and most of the down hairs fall off;

[0041] B. Furnace loading: put the tobacco leaves collected in step A into the barn, and the smoke density is 43.5kg / m 3 , fill the smoke to more than 95% of the volume of the barn;

[0042]C. Yellowing: including the early stage of yellowing and the late stage of yellowing. In the early stage of yellowing, the dry bulb temperature is raised from 29°C to 35°C, and the wet bulb temperature is adjusted from 26°C to 34°C at a heating rate of 1°C / 1.5h. , stabilize the dry and wet bulb temperatures, bake for 48 hours, and bake until the bottom tobacco leaves turn yellow by 1 / 3; then enter the later stage of yellowing, raise the dry bulb temperature to 41°C at a heating rate of 1°C / 1.5h, and the wet bulb temperature Adjust to 35°C, stabilize the dry and wet bulb temperatures, and bake for 24 hours until the tobacco leaves ...

Abstract

The invention discloses a baking method capable of improving the smoking quality of flue-cured tobaccos K326. The method specially comprises the following steps of harvesting, charging in stoves, yellowing, color fixation and killing-out. The problems of likely tobacco leaf yellowing, difficult color fixation, tobacco leaf stiffness after baking and insufficient aroma in the intensive baking process by controlling optimizing combinations of temperature, humidity and baking time, the first-class tobacco proportion, average price and the sensory smoking quality of baked tobaccos are effectively improved, and a technical support is provided for optimization of an adjustment and control technology adopted after intensive baking and yellowing.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco curing, and in particular relates to a curing method capable of improving the smoking quality of flue-cured tobacco K326. Background technique [0002] The K326 variety is an excellent flue-cured tobacco variety selected and bred in the United States. It has a history of more than 30 years and is still one of the excellent varieties. This variety was introduced to Yunnan in 1985 and has been popularized and planted throughout the province. In the 1990s, it became the largest variety in Yunnan and even in the whole country. The yield of K326 is medium to high, the color is orange, the color is full, the oil is rich, the smoke is strong, and the strength is strong. It is an ideal main tobacco leaf. The problems of K326 baking mainly include: the lower leaves are easy to turn green, the main reason is that the climate drought leads to large differences in leaf maturity, tissue stiffness, ...
