Convenient and efficient bulk curing method for flue-cured tobacco

Abstract

The invention discloses a convenient and efficient bulk curing method for flue-cured tobacco, and belongs to a curing or preparation method for the flue-cured tobacco. The method comprises the steps of tobacco harvesting, rod tying or tobacco clamping, loading on a heatable brick bed, preparation for curing, yellowing, color fixing and killing-out of a conventional method. The method has the characteristics that tobacco is controlled to be fully yellowed in a high-temperature and high-humidity environment, and is bright in color; main moisture exhaust drying temperature is fixed to be 44 DEG C, and color is fixed under low humidity and high moisture exhaust rate. Compared with the conventional curing method, the method has the advantages that the cured tobacco is bright and shining in color; tobacco with green stems and ash is reduced or eliminated; the tobacco is high in flexibility and softness; tobacco with diseases and special tobacco can also be cured to be yellow and scented; the tobacco of more than two parts and different maturities in the same curing barn can be cured; the curing method is simple, high in operability and easy to master and accept by curing personnel; the curing time is shortened by 10 to 15 hours; the tobacco curing quality and benefits are improved.

Description

technical field [0001] The invention belongs to a method for curing or preparing flue-cured tobacco. Background technique [0002] Flue-cured tobacco is an important economic crop in my country, with an annual planting area of ​​more than 1 million hectares. "Baking" is an important part of flue-cured tobacco production. As the saying goes, "flue-cured tobacco is a treasure, but if it is not baked well, it is grass." The purpose of curing is to maximize the quality of tobacco leaves formed in the field, to meet the needs of cigarette industry enterprises for raw materials of tobacco leaves, and to maximize the production benefits of tobacco farmers. And baking is often the most difficult to grasp in the production of flue-cured tobacco, requiring high operating technology, and the most important production link. In the annual production of tobacco leaves, the loss due to improper curing accounts for more than 15%. The currently used "three-stage intensive curing process" ...

AI Technical Summary

Problems solved by technology

The currently used "three-stage intensive curing process" or "three-stage six-step intensive curing process" and many other curing methods (processes or technologies) are more complicated to operate, difficult for tobacco farmers to master, and cannot guarantee the maximum quality of tobacco leaves in the field. Quality, such as the poor color of the roasted tobacco leaves, slightly green smoke, a lot of gray smoke, some diseased leaves, and special tobacco leaves that cannot be roasted to a good effect, etc.; There are problems such as the main tendon bending after the tobacco leaves are dried, the leaves are not retracted, the leaves are hard, it is not easy to regain moisture, and the cigarette industry does not like it.
