A kind of baking method of flue-cured tobacco

Abstract

The invention discloses a flue-cured tobacco baking method, and belongs to the technical field of tobacco blending and making. According to tobacco baking properties of a flue-cured tobacco variety of Yun tobacco 105, the whole tobacco baking process is a three-stage seven-step tobacco baking process including treatments at early stage of yellowing, middle stage of yellowing, late stage of yellowing, early stage of color fixing, late stage of color fixing, early stage of stem drying and later stage of stem drying according to the temperature and humidity, and the quality of the baked tobacco is greatly improved; the baking process is high in operability and can obviously improve the tobacco quality of flue-cured tobacco, increase the ratio of first-class tobacco and decrease the smoke rate; after baking is conducted, the ratio of first-class tobacco and middle-grade tobacco in the tobacco is increased by 10.65% or above, the ratio of variegated tobacco is decreased by 1.67% or above, and the greenish ratio of the tobacco on the upper-middle part is decreased by 7% or above; the production value is increased by 11.75% or above, the baked tobacco is bright in color and luster and oily, chemical components tend to coordination, the sugar-nicotine ratio, nitrogen-nicotine ratio and total nicotine all meet the quality evaluation criteria of original tobacco chemical compositions, the style and characteristics of Yun tobacco 105 can be fully embodied, and the income of tobacco growers is increased.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco, in particular to a method for curing flue-cured tobacco. Background technique [0002] Curing is one of the important measures of tobacco leaf production. The fresh tobacco leaves harvested in the field must be roasted to reflect its excellent quality and high commodity value. The curing characteristics of tobacco leaves are restricted by many factors such as variety, soil and climate, among which the most important factor is the variety. Different flue-cured tobacco varieties have different curing characteristics. At present, the flue-cured tobacco curing process is generally a three-stage curing process, that is, the curing process is divided into three stages: yellowing, color fixing, and tendon drying. Temperature 36-38°C, yellowing complete temperature 40-42°C, wet bulb temperature 1-4°C lower than dry bulb temperature; color fixing stage: dry bulb temperature 54-55°C, wet bulb t...

AI Technical Summary

Problems solved by technology

At present, there is no specific report on the roasting process of Yunyan 105, but Yunyan 105 adopts the traditional three-stage roasting process, and the proportion of upper medium tobacco after roasting is only about 65.7%, and the proportion of middle and upper tobacco leaves is slightly green. High, more than 25.6%, and the proportion of variegated tobacco in the upper part of the tobacco leaf is large, reaching more than 5.36%, which cannot reflect the curing characteristics of Yunyan 105 flue-cured tobacco
