Intensive curing barn precise curing process for flue-cured tobacco

Abstract

The invention discloses an intensive curing barn precise curing process for flue-cured tobacco. The process mainly comprises three curing stages, namely a yellowing stage, a color fixing stage and a stem drying stage, wherein three key temperature and humidity points are controlled in the yellowing stage; four key temperature and humidity points are controlled in the color fixing stage; one key temperature and humidity point is controlled in the stem drying stage; a flue-cured tobacco temperature and humidity automatic control system is adopted in an entire curing process; and a temperature sensor and a humidity sensor are arranged on the top layer of a down-draft intensive curing barn or the bottom layer of an up-draft bulk curing barn. Through the process, error and loss of manual operation brought by operation by experience are reduced, curing quality of tobacco leaves is improved, curing cost is reduced, and high operability is guaranteed. As proved, badly cured tobacco such as green and miscellaneous tobacco and the like is obviously reduced, proportion of orange tobacco and first-class tobacco is increased, the cured tobacco has a loose structure and increased oil content, and appearance quality inside and outside the tobacco leaves and availability are obviously improved.

Description

Technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a precise baking process in a dense barn with tobacco in a hanging rod mode or a cigarette clip mode. Background technique [0002] In the production of flue-cured tobacco, curing is the last important link that determines the yield and quality of tobacco leaf, and it is also the weakest link in China’s tobacco leaf production, which directly affects the sustainable development of tobacco leaf in my country. The roasting quality of tobacco leaves is mainly restricted by the quality of fresh tobacco leaves, roasting equipment and roasting technology. In recent years, with the development of three-stage production and the popularization and application of intensive baking equipment, the quality of fresh tobacco leaves and baking equipment in Datian have been significantly improved. In the baking process, the three-stage baking process is still used, bu...
