Moisture-regain technology for improving loose tobacco baking quality

Abstract

The invention belongs to the field of tobacco processing, and particularly relates to a moisture-regain technology for improving the loose tobacco baking quality. By means of the moisture-regain technology, the visual width of stored tobacco is remarkably reduced, the tobacco is well stored and can be stored for a long time, the storage time can meet the requirements of industrial manufacturers, and the tobacco quality also is improved. The moisture-regain technology comprises the following steps of (1) conducting tobacco loading, wherein collected fresh tobacco leaves are placed in a curing barn in a classified mode, and tobacco leaves are loaded to a kang according to the standard of loose tobacco curing; (2) conducting sealing, wherein after each layer of tobacco leaves are placed on the kang, the tobacco leaves and the periphery of the curing barn are completely sealed; (3) conducting curing, wherein curing lasts for 110-130 hours, then colors of the tobacco leaves are fixed, curing is finished, and after stems of the tobacco leaves are dried and cured, a fan is kept normally operating; (4) conducting moisture regain, wherein fuel continues to be added to keep the temperature in the curing barn ranging from 66-68 DEG C, the curing barn is closed, and water is supplied to fan blades to form humid and hot air so that moisture regain can be conducted on the cured tobacco leaves; (5) conducting kang discharging, wherein the moisture-regained tobacco leaves are discharged from the kang; (6) after the tobacco leaves are stacked for 6-8 days, deactivation of enzymes and impurity removing are conducted, the tobacco leaves are classified primarily, and then the tobacco leaves are baled after being naturally folded again.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a moisture regaining process for improving the quality of cured tobacco leaves of loose tobacco. Background technique [0002] Loose leaf curing is a new technology currently popularized by the tobacco industry. It is characterized by reducing labor intensity, reducing the procedure of tying rods and lowering tobacco, increasing the weight of tobacco leaves, increasing the output value of tobacco leaves, and increasing the amount of tobacco in the curing room by 30-50% compared with conventional methods. Accelerating the progress of harvesting and reducing the cost of curing per unit of tobacco leaves is a better way for tobacco farmers to save labor and reduce costs, improve quality and increase, and is a new practical technology that has been promoted nationwide in recent years. [0003] The current methods for curing loose tobacco include: (1) collecting: collect ...

AI Technical Summary

Problems solved by technology

[0004] There are problems in loose leaf baking: the amount of tobacco is large, the leaves are dense, and they are pressed against each other. During the process of color fixing and tendon drying, the tobacco leaves cannot shrink freely. The weight of the tobacco leaves increases after roasting, but because of the large surface area, the leaves appear thinner and the inner quality is poor; slow water absorption on both sides of the leaf veins tends to cause stiff and smooth tobacco leaves, and the tobacco leaves have a tight structure, which is not liked by the factory; the tobacco leaves do not shrink. All kinds of variegated colors and plaques are completely exposed, it is difficult to match the acquisition standard

[0005] At the same time, after loose roasting, the tobacco leaves near the wall, the heating room, the doorway, and the leaf stalks in the middle of the curing room protrude from the air distribution plate, and the tobacco leaves that are improperly filled with tobacco during curing will cause the leaf veins to bend and affect the appearance of the tobacco leaves. The quality also affects the income of tobacco farmers; when the loose-cured tobacco leaves are roasted, the tip of the leaf faces upward, and the tip of the tobacco leaves curls after drying, and the apparent length of the tobacco leaves becomes shorter

The visual effect is poor; the structure of loose-leaf cured tobacco leaves is tight, and the tobacco leaves are not bad for storage after the traditional method regains moisture. The availability of tobacco leaves is low, and industrial enterprises have great opinions, which seriously affects the promotion of loose-leaf curing
