Problems solved by technology

[0005] At present, the way to solve the low-pH flue-cured tobacco planting soil such as paddy soil is generally to use crop rotation, but it will lead to a decrease in the income of tobacco farmers; there are also soil improvers to improve the soil structure, so as to increase the pH of the soil and reduce the activity of Mn2+ ions, thereby reducing Tobacco absorption can prevent gray smoke caused by manganese poisoning in tobacco leaves, but there are also problems of uneven soil conditions, difficulty in controlling the dosage and high cost
Of course, there are also attempts to adjust the curing process to improve the quality of manganese-poisoned tobacco leaves after roasting. Quality, prevent or reduce hanging ash smoke, which also results in higher requirements for the experience of baking personnel, each person adopts their own methods, not only the operation is complicated, but also the improvement effect is unstable or limited

Embodiment 1

[0028] S100: The central tobacco leaves of KRK26 variety manganese-poisoned flue-cured tobacco were harvested in Ziwu Town, Chuxiong City, with copper-yellow leaves, gray-black spots around the veins, and most of the hairs fell off, and were braided according to conventional methods.

[0029] S200: Tobacco leaves that have been braided at 42kg / m 3 Fill the smoke density to more than 95% of the volume of the air-flow descending intensive curing barn, and wait for baking.

[0030] S300: Including the early stage of yellowing, the middle stage of yellowing, and the late stage of yellowing. In the early stage of yellowing, the temperature of the dry bulb is increased from room temperature to 34°C at a rate of 1°C / h, and the temperature of the wet bulb is adjusted from room temperature to 33°C. Bake at the temperature of dry and wet bulbs for 12 hours, and then increase the temperature of dry bulbs from room temperature to 37 °C at a rate of 1 °C / 2 h, and adjust the temperature of ...

Embodiment 2

[0034] S100: The central tobacco leaves of KRK26 variety manganese-poisoned flue-cured tobacco were harvested in Ziwu Town, Chuxiong City, with copper-yellow leaves, gray-black spots around the veins, and most of the hairs fell off, and were braided according to conventional methods.

[0035] S200: Tobacco leaves that have been braided at 42kg / m 3 Fill the smoke density to more than 95% of the volume of the air-flow descending intensive curing barn, and wait for baking.

[0036] S300: Including the early stage of yellowing, the middle stage of yellowing, and the late stage of yellowing. In the early stage of yellowing, the temperature of the dry bulb is increased from room temperature to 35°C at a rate of 1°C / h, and the temperature of the wet bulb is adjusted from room temperature to 33.5°C. Bake at the temperature of dry and wet bulbs for 18 hours, then increase the temperature of dry bulbs from room temperature to 37.5 °C at a rate of 1 °C / 2 h, and adjust the temperature of ...

Embodiment 3

[0040] S100: The central tobacco leaves of KRK26 variety manganese-poisoned flue-cured tobacco were harvested in Ziwu Town, Chuxiong City, with copper-yellow leaves, gray-black spots around the veins, and most of the hairs fell off, and were braided according to conventional methods.

[0041] S200: Tobacco leaves that have been braided at 42kg / m 3 Fill the smoke density to more than 95% of the volume of the air-flow descending intensive curing barn, and wait for baking.

[0042] S300: Including the early stage of yellowing, the middle stage of yellowing, and the late stage of yellowing. In the early stage of yellowing, the temperature of the dry bulb is raised from room temperature to 35°C at a rate of 1°C / h, and the temperature of the wet bulb is adjusted from room temperature to 34°C. Bake at the temperature of dry and wet bulbs for 24 hours, then increase the temperature of dry bulbs from room temperature to 38 °C at a rate of 1 °C / 2 h, and adjust the temperature of wet bul...

Abstract

The invention discloses a flue-cured tobacco curing method for effectively improving the quality of manganese-poisoned tobacco leaves. Baking is carried out, and after the yellowing period, color fixing period and gluten drying period, the roasted tobacco leaves can be obtained. Aiming at the characteristics of manganese poisoned tobacco leaves, the present invention reduces the limitations of existing curing methods on manganese poisoned tobacco leaves by optimizing the combination of temperature, humidity and curing time during the curing process, and solves the problem of manganese poisoning in tobacco leaves causing the flue-cured tobacco leaves to be brown. It can effectively improve the proportion of high-quality tobacco, the average price, and the sensory evaluation quality of tobacco leaves after roasting, thereby improving the quality of roasted tobacco leaves with manganese poisoning, and significantly reducing the loss of tobacco farmers. It has simple process, easy operation, and improved effect. Notable feature.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing, and in particular relates to a method for curing tobacco with simple process, easy operation and remarkable effect, which can effectively improve the quality of manganese-poisoned tobacco leaves. Background technique [0002] Tobacco farmers often say that "cured tobacco is a treasure out of the fire. If it is roasted well, it is a treasure, but if it is not roasted, it is like dung grass." It vividly illustrates the close relationship between roasting and tobacco leaf quality. Baking has four effects on fresh tobacco leaves, one is to form the appearance quality of tobacco leaves; the other is to form the chemical quality of tobacco leaves; the third is to form the physical quality of tobacco leaves; the fourth is to form the smoking quality of tobacco leaves. It can be seen that baking is a key link in forming the quality of tobacco leaves. [0003] However, during the planting and curi...
