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: harvest the flue-cured tobacco leaves with white ribs, pale yellow leaves, and most of the hairs falling off;

[0029] B. Furnace loading: the tobacco leaves collected in step A are loaded into the curing barn with a density of 42kg / m 3 , Fill the tobacco to more than 95% of the volume of the barn

[0030] C. Yellowing: Including the initial stage of yellowing and the late stage of yellowing. The initial stage of yellowing is to increase the dry bulb temperature from 29°C to 34°C, and adjust the wet bulb temperature from 26°C to 33°C. Stabilize the dry and wet bulb temperatures, bake for 47h, and the bottom tobacco leaves will turn yellow by 1 / 3; then into the late stage of yellowing, increase the dry bulb temperature to 40°C at a heating rate of 1℃ / 2h, and adjust the wet bulb temperature to 35℃, stable dry and wet bulb temperature, baking for 23h, the tobacco leaves will turn yellow completely;

[0031] D. Color fixation: including the initial stage of fixatio...

Embodiment 2

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

[0035] B. Furnace loading: the tobacco leaves collected in step A are loaded into the curing barn with a density of 45kg / m 3 , Fill the tobacco to more than 95% of the volume of the curing barn;

[0036] C. Yellowing: including the initial stage of yellowing and the late stage of yellowing. The initial stage of yellowing is to increase the dry bulb temperature from 29°C to 36°C and adjust the wet bulb temperature from 27°C to 35°C at a heating rate of 1°C / 1h. Stabilize the dry and wet bulb temperature, bake for 49h, the bottom tobacco leaves will turn yellow by 1 / 3; then enter the late stage of yellowing, increase the dry bulb temperature to 42°C, and adjust the wet bulb temperature to 36℃, stable dry and wet bulb temperature, baking for 25h, the tobacco leaves will turn yellow completely;

[0037] D. Color fixation: including the ini...

Embodiment 3

[0040] A. Harvesting: harvest the flue-cured tobacco leaves with white ribs, pale yellow leaves, and most of the hairs falling off;

[0041] B. Furnace loading: load the tobacco leaves collected in step A into the curing barn, with a density of 43.5kg / m 3 , Fill the tobacco to more than 95% of the volume of the curing barn;

[0042] C. Yellowing: including the initial stage of yellowing and the late stage of yellowing. The initial stage of yellowing is to increase the dry bulb temperature from 29°C to 35°C and adjust the wet bulb temperature from 26°C to 34°C at a heating rate of 1°C / 1.5h. , Stabilize the dry and wet bulb temperature, bake for 48h, and the bottom tobacco leaves will turn yellow by 1 / 3; then enter the late stage of yellowing, increase the dry bulb temperature to 41℃, the wet bulb temperature at a heating rate of 1℃ / 1.5h Adjust to 35℃, stabilize the dry and wet bulb temperature, bake for 24h, and the tobacco leaves will turn yellow completely;

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 roasting, and specifically relates to a roasting 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 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 promoted and planted throughout the province. It was the largest variety in Yunnan and even the country in the 1990s. 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 a very ideal main ingredient tobacco. The main problems of K326 baking include: the lower leaves are easy to wither. The main reasons include climatic drought leading to large differences in leaf maturity, stiff tissues, slow yellowing during yellowing, and un...
