Embodiment 1

[0016] (1) Yellowing stage: The technical essentials are to speed up the yellowing speed and reduce the consumption of contained substances. The heating rate is 1°C / hour, the dry bulb temperature is 37-38°C, and the difference between dryness and humidity is 2-3°C. The bottom shed tobacco leaves are required to be soft and basically turn yellow. After reaching the target, the temperature is raised at a rate of 1°C / 3 hours, and the dry bulb temperature reaches 42°C. The main veins of the bottom shed tobacco leaves are required to be soft, the tips of the leaves are curled, and the top shed tobacco leaves are basically all yellow.

[0017] (2) Color fixing stage: The technical essentials are dehumidification in advance and enhanced dehumidification. Raise the dry bulb temperature to 48-50℃ at a speed of 1℃ / 2-3 hours, the veins of the tobacco leaves in the bottom shed will turn yellow, and more than half of the leaves will be dry. If this goal is not reached, the curing time sho...

Abstract

The invention discloses a method for preparing flue-cured tobacco leaves with high water content, which includes (1) yellowing stage: the technical essentials are to accelerate the yellowing speed and reduce the consumption of contained substances. (2) Color fixing stage: The technical essentials are dehumidification in advance and enhanced dehumidification. (3) Dry gluten stage: the technical essentials are to control the dry bulb and limit the wet bulb. The method can reduce the risk of roasting dregs of flue-cured tobacco leaves with higher water content, improve the quality of tobacco leaves of this type, improve the grade quality after modulation, and increase the income of tobacco farmers.

Description

technical field [0001] The invention relates to a method for preparing flue-cured tobacco leaves with high water content. Background technique [0002] For example, the rainfall in the maturity stage of flue-cured tobacco is relatively large, and it is generally easy to produce tobacco leaves with high water content; long-term rainy and lack of light and the tobacco leaves in the second shed generally have high water content, and it is easy to produce tobacco leaves with high water content. However, if there is a lot of floating water on the surface of the tobacco leaf, its internal water content has not changed greatly, and it does not belong to the tobacco leaf with high water content. The flue-cured tobacco leaves with higher moisture content generally show that the internal dry matter is not sufficient enough, and they are easy to be roasted during curing, resulting in low or no use value of the cured tobacco leaves, which affects the comprehensive income of tobacco farm...
