In the invention, the temperature of the automatic control equipment in the curing barn 3 is set to be 30 ℃, and the relative humidity is 80-85%. Bundling the tobacco leaves in sequence, and ensuring the tobacco leaves to be loose as much as possible during bundling so as to be beneficial to uniform moisture regain; when the tobacco bundles are placed, the tobacco bundles are placed in the curing barn with the leaf stalks downward and the leaf tips upward and upside down.
The operation flow of the tobacco leaf large-scale steam conditioning process is as follows: transporting tobacco leaves to a moisture regaining point → shaking and scattering → bundling snakeskin bags → loading kang → regaining moisture → classifying the lower kang. The specific operation is as follows:
1. transporting tobacco leaves to a moisture regain point
Tobacco growers transport the leaves to be separated to a moisture regain point according to the arrangement of moisture regain point personnel, and carry a small amount of snakeskin bags for bundling cigarettes.
2. Tobacco leaf shaking powder
And opening the tobacco bundle, shaking and scattering tobacco leaves, and then bundling according to the size of the snake skin bag. Care should be taken during this operation to loosen the tobacco leaves as much as possible, since the degree of loosening determines the uniformity and effectiveness of the tobacco leaf conditioning, the looser the better the effectiveness.
3. Heatable brick bed
And (3) flatly placing the tobacco clips in the curing barn, and inversely placing the scattered and bundled tobacco leaves into the curing barn (with the leaf stalks downward and the leaf tips upward). Generally, 2 layers of kang are arranged. When the brick bed is loaded, the bundle is tightly bound to prevent larger gaps from occurring, so that the tobacco leaf moisture regaining effect is effectively improved. After the kang is loaded, the door of the baking room is closed. One curing barn can hold about 3000 tobacco leaves.
4. Moisture regain
After the kang is loaded, firstly, the steam generator is started, and then, the automatic control equipment of the heating device in the heating chamber of the curing barn is started and ignition is carried out. The temperature of the self-control equipment of the curing barn is set to be 30 ℃, the relative humidity is 80-85%, when the steam generator starts to generate steam, the steam ball valve 4 is opened, the steam is conveyed to the heating chamber of the curing barn, then the circulating fan 6 of the curing barn is started (the circulating fan can only use small wind), the damp and hot air is conveyed into the heating chamber of the curing barn by utilizing the wind power of the circulating fan, and the dry air in the tobacco containing chamber after being absorbed by the tobacco leaves is conveyed into the heating chamber for humidifying again. The uniformity of the air humidity in the whole smoke containing chamber can be adjusted through forced wind power circulation of the circulating fan. In the moisture regaining process, steam is generated by a steam generator or a boiler to improve the humidity in the curing barn, the tobacco leaves are heated to 30 ℃ by the curing barn, so that the tobacco leaves are subjected to natural moisture absorption under the conditions of high temperature and high humidity (30 ℃ and relative humidity of 80% -85%), and the moisture content of the tobacco leaves is improved. The whole moisture regaining process of the upper tobacco leaves is about 6 to 8 hours (the middle tobacco leaves only need about 2 hours), and the moisture regaining process is finished when the base parts of the main veins of the tobacco leaves are not easy to break and the leaves are soft. At this time, the water content of the lower kang tobacco leaves exceeds the upper limit of the purchasing control of 18 percent.
5. Lower kang grading
And after the tobacco leaves are completely dampened, the tobacco leaves are put into a kang and are transported to a specialized tobacco dispersing and grading point for grading. The moisture content of the tobacco leaves after moisture regain is large, the moisture of the tobacco leaves is lost under the low-temperature drying grading condition, and if the moisture is about 17% of the purchased moisture, the operation of a humidifier is controlled in the grading process, only the effect of slightly increasing the air is needed, and the excessive moisture is not needed to be added, so that the moisture content of the tobacco leaves is too large.
In 2018 to 2019, in order to solve the problem of scale moisture regain of tobacco leaves, a study on a scale steam moisture regain test of the tobacco leaves is developed. The verification proves that the method has good operability and is widely applied to the southern Anhui tobacco district.
The process has the advantages that: the moisture regain effect is good, the moisture content of the tobacco leaves after moisture regain is uniform, the tobacco leaves absorb molecular water, and the tobacco leaves are not easy to mildew after being packaged into pieces; the moisture regain cost is low, and the moisture regain cost of each kilogram of tobacco leaves is only 9 minutes; the tobacco grower has obvious income increasing effect. The tobacco grower can increase the income per mu by about 130 yuan. The tobacco leaf income increase after moisture regaining is mainly shown in three aspects: firstly, the moisture content of the tobacco leaves is improved, and the moisture content of the tobacco leaves is improved by 2-3 percent after moisture regain; second, the tobacco leaf is reduced in size in the grading process, and the size is reduced by about 1 percent; and thirdly, the first-class smoke proportion is improved, and through measurement and calculation, the first-class smoke proportion of 3 percentage points can be improved by moisture regain, and meanwhile, the upper smoke proportion of 3 percentage points is reduced.
The tobacco leaf conditioning equipment and the conditioning process have the advantages of low cost, good conditioning effect, capability of improving the quality of tobacco leaves, stronger practicability and better application prospect.
