Problems solved by technology

Due to long-term flooding, the viscosity of paddy soil increases, the sealing property increases, and the air permeability becomes poor. As a result, iron ions in the soil are in the state of ferrous ions, and a large amount enters the soil solution. Plants planted in this type of paddy soil absorb ferrous ions. Iron ions will cause excess ferrous ions and cause poisonous to plants
Tobacco under stress will produce brown to purple fragile tobacco leaves, seriously affecting the quality of tobacco leaves and causing huge losses to the income of tobacco farmers
[0005] At present, for the tobacco leaves that have absorbed ferrous ions in paddy soil and caused iron poisoning, due to the special internal causes, the curing process must be matched with the quality of the tobacco leaves, that is, it must be flexibly adjusted according to the specific curing characteristics of the tobacco leaves to ensure that the tobacco leaves are cured. Quality, prevent or reduce hanging ash smoke, thereby also cause higher experience requirement to the roasting personnel of iron poisoning tobacco leaf in the prior art, each person adopts the method of showing their own abilities according to actual subjective judgment, not only complicated operation, but also improved Unstable or limited effect
As a result, there is no mature targeted baking technology in the prior art, and the baking method of ordinary tobacco leaves cannot be applied to the baking of iron-poisoned tobacco leaves. Poisoned tobacco leaves lost due to improper curing

Embodiment 1

[0028] S100: The middle tobacco leaves of KRK26 variety iron poisoning flue-cured tobacco with white tendons, slender and chlorotic leaves and most of the down hairs were harvested in Ziwu Town, Chuxiong City, and stalks were braided as usual.

[0029] S200: Tobacco leaves that have been braided at 43.5kg / 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 and the late stage of yellowing. In the early stage of yellowing, the temperature of the dry bulb is raised from room temperature to 37°C, and the temperature of the wet bulb is adjusted from room temperature to 36.5°C at a heating rate of 1°C / h to stabilize the dry bulb and wet bulb. Baked at the temperature for 22 hours until 80% of the tobacco leaves in the high-temperature zone turn yellow; then enter the later stage of yellowing, raise the dry bulb temperature to 41°C at a heating rate of 1°...

Embodiment 2

[0034] S100: The middle tobacco leaves of KRK26 variety iron poisoning flue-cured tobacco with white tendons, slender and chlorotic leaves and most of the down hairs were harvested in Ziwu Town, Chuxiong City, and stalks were braided as usual.

[0035] S200: Tobacco leaves that have been braided at 43.5kg / 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 and the late stage of yellowing. In the early stage of yellowing, the temperature of the dry bulb is raised from room temperature to 38°C at a rate of 1°C / 1.5h, and the wet bulb temperature is adjusted from room temperature to 37°C to stabilize dry and wet. The temperature of the bulb is baked for 23 hours until 80% of the tobacco leaves in the high temperature zone turn yellow; then enter the later stage of yellowing, with a heating rate of 1°C / 3h, raise the temperature of the dry bulb to 42°C, a...

Embodiment 3

[0040] S100: The middle tobacco leaves of KRK26 variety iron poisoning flue-cured tobacco with white tendons, slender and chlorotic leaves and most of the down hairs were harvested in Ziwu Town, Chuxiong City, and stalks were braided as usual.

[0041] S200: Tobacco leaves that have been braided at 43.5kg / 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 and the late stage of yellowing. In the early stage of yellowing, the temperature of the dry bulb is raised from room temperature to 38°C, and the temperature of the wet bulb is adjusted from room temperature to 37°C at a heating rate of 1°C / h to stabilize the dry bulb and wet bulb. Baked at the temperature for 24 hours until 80% of the tobacco leaves in the high-temperature zone turn yellow; then enter the later stage of yellowing, with a heating rate of 1°C / 3h, raise the dry bulb temperature to...

Abstract

The invention discloses a flue-cured tobacco curing method for effectively improving the quality of iron-poisoned tobacco leaves. The flue-cured tobacco curing method comprises the steps of harvestingproper mature tobacco leaves with iron poisoning symptoms, and braiding the tobacco leaves into rods; loading the braided tobacco leaves into a curing barn; and curing the loaded tobacco leaves, andobtaining the cured tobacco leaves after a yellowing period, a color fixing period and a stem drying period. In allusion to the characteristics of iron-poisoned tobacco leaves, the temperature, the humidity and the curing time in the curing process are optimally combined, enzymatic browning reaction of the tobacco leaves in the curing process is reduced and even eliminated, so that the problem ofash hanging of flue-cured tobacco leaves caused by iron poisoning of the tobacco leaves is solved, the proportion and the average price of first-class tobacco and the sensory evaluation quality of thecured tobacco leaves are improved, losses of tobacco growers are remarkably reduced, and the method has the advantages of being simple in process, easy to operate and remarkable in improvement effect.

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 iron-poisoned tobacco leaves. Background technique [0002] The unique geographical climate and good natural environment make Yunnan a sacred place for high-quality tobacco production. Yunnan tobacco leaves are uniform in color, long in aroma and sweet in taste, and have become the main raw material of cigarettes. With the gradual reduction of tobacco planting area in the north, Yunnan has become a major tobacco planting province, with more than 1 million tobacco planters, accounting for about 50% of the country's total tobacco output, and playing a pivotal role in Yunnan's social and economic development. [0003] However, it is difficult to obtain high-quality tobacco leaves obtained in the field without a scientific tobacco lea...
