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: In Ziwu Town, Chuxiong City, the central tobacco leaves of KRK26 iron-poisoned flue-cured tobacco with white rib, slender and chlorotic leaves and most of the hairs falling off were harvested and woven as usual.

[0029] S200: Press 43.5kg / m of woven tobacco leaves 3 The density of the smoke should be filled to more than 95% of the volume of the air-flow descending intensive roasting room, and it should be roasted.

[0030] S300: Including the initial yellowing stage and the late yellowing stage. In the initial yellowing stage, the dry bulb temperature was increased from room temperature to 37 °C at a heating rate of 1 °C / h, and the wet bulb temperature was adjusted from room temperature to 36.5 °C to stabilize dry and wet bulbs. The tobacco leaves in the high temperature area were baked for 22 hours until 80% of the tobacco leaves in the high temperature area turned yellow; then in the late stage of yellowing, at a heating rate of 1°C / 3h, the dry bulb temperature...

Embodiment 2

[0034] S100: In Ziwu Town, Chuxiong City, the central tobacco leaves of KRK26 iron-poisoned flue-cured tobacco with white rib, slender and chlorotic leaves and most of the hairs falling off were harvested and woven as usual.

[0035] S200: Press 43.5kg / m of woven tobacco leaves 3 The density of the smoke should be filled to more than 95% of the volume of the air-flow descending intensive roasting room, and it should be roasted.

[0036]S300: Including the initial yellowing stage and the late yellowing stage. At the initial stage of yellowing, the dry bulb temperature was increased from room temperature to 38 °C at a heating rate of 1 °C / 1.5 h, and the wet bulb temperature was adjusted from room temperature to 37 °C to stabilize dry and wet conditions. The temperature of the bulb was baked for 23 hours until 80% of the tobacco leaves in the high temperature area turned yellow; then in the late stage of yellowing, the dry bulb temperature was raised to 42°C at a heating rate of ...

Embodiment 3

[0040] S100: In Ziwu Town, Chuxiong City, the central tobacco leaves of KRK26 iron-poisoned flue-cured tobacco with white rib, slender and chlorotic leaves and most of the hairs falling off were harvested and woven as usual.

[0041] S200: Press 43.5kg / m of woven tobacco leaves 3 The density of the smoke should be filled to more than 95% of the volume of the air-flow descending intensive roasting room, and it is to be roasted.

[0042] S300: including the initial yellowing stage and the late yellowing stage. In the initial yellowing stage, the dry bulb temperature is increased from room temperature to 38 °C at a heating rate of 1 °C / h, and the wet bulb temperature is adjusted from room temperature to 37 °C to stabilize dry and wet bulbs. The tobacco leaves in the high temperature area were baked for 24 hours until 80% of the tobacco leaves in the high temperature area turned yellow; then in the late stage of yellowing, at a heating rate of 1°C / 3h, the dry bulb temperature was ...

Abstract

The invention discloses a flue-cured tobacco curing method for effectively improving the quality of iron-poisoned tobacco leaves. Toasting 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 iron poisoning tobacco leaves, the present invention reduces or even eliminates the enzymatic browning reaction of tobacco leaves during the curing process by optimizing the combination of temperature, humidity and curing time in the curing process, so as to solve the problem of iron poisoning on flue-cured tobacco leaves causing ash to hang on the flue-cured tobacco leaves problems, thereby improving the proportion of high-quality tobacco, the average price, and the sensory evaluation and smoking quality of the cured tobacco leaves, and significantly reducing the losses of tobacco farmers. It has the characteristics of simple process, easy operation, and significant improvement effect.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing, and in particular relates to a curing method for flue-cured tobacco which is simple in process, easy to operate and has obvious effect and can effectively improve the quality of iron poisoned tobacco leaves. Background technique [0002] The unique geographical climate and good natural environment make Yunnan a holy land for high-quality tobacco production. Yunnan tobacco leaves have uniform color, long aroma and sweet taste, and have become the main raw material of cigarettes. With the gradual reduction of the tobacco planting area in the north, Yunnan has become a major tobacco-growing province, with more than 1 million tobacco growers, accounting for about 50% of the country's total tobacco production, which plays a pivotal role in Yunnan's social and economic development. [0003] However, it is difficult to obtain high-quality tobacco leaves for high-quality tobacco leaves obtained i...
