Problems solved by technology

[0003] Some excellent varieties (such as k326) grow well in the field, but due to improper curing operations, the proportion of curing loss is relatively large; In the rainy season, the tobacco leaves are mostly rainwater tobacco, green tobacco, etc. This kind of tobacco adopts the existing three-stage curing method, which is very easy to cause serious ash, and the proportion of variegated smoke is large, which seriously affects the appearance quality and quality of the tobacco leaves. Tasting aroma affects the overall quality of tobacco leaf raw materials

example 1

[0016] Example 1: Curing test of K326 upper tobacco leaves

[0017] K326 is a characteristic flue-cured tobacco variety, and its upper tobacco leaves are easy to hang ash, which often affects the further promotion of this variety. Now through the comparative experiments of three loose leaf curing processes, the effectiveness of the present invention on the appearance quality of K326 upper tobacco leaves is verified. sex.

[0018] The baking process comparison settings are as follows:

[0019] Control group: Conventional three-stage tobacco leaf baking process, 38℃ / 36℃ for yellowing, 42 / 34℃ for 15 hours, 45℃ / 35 for 10 hours; 48~50℃ / 35~36℃ 10 hours; after baking at 52~54 / 35~36℃ for 20 hours, it enters the dry gluten period.

[0020] Embodiment method one of the present invention: Bake at 38°C / 36°C for 25 hours; at 40 / 35°C for 5 hours, then bake at 40 / 34°C for 15 hours; at 42 / 33°C for 20 hours; at 45 / 34°C Bake at low temperature for 15 hours; bake at 48 / 35°C for 8 hours; ...

[0023] Example 2: Baking test of greenish smoke

[0024] Using Yunyan 87 as the material, it was planted in Xingren County, Qianxinan Prefecture, Guizhou Province in 2015. The weather in the early stage of flue-cured tobacco field development was dry, and the growth and development of tobacco leaves were slow; but in the later stage of tobacco leaf growth and development, due to more rain, the tobacco leaves were mostly rainwater green leaves. It is difficult to complete the tobacco leaf curing effectively by normal curing process, and the comparative test of three (hanging rod) curing processes is now used to verify the effectiveness of the present invention on the curing quality of rainy green tobacco.

[0025] The baking process comparison settings are as follows:

[0026] Control group: Conventional three-stage tobacco leaf baking process, 38℃ / 36℃ for yellowing, 42 / 36℃ for 14 hours, 45℃ / 37 for 12 hours; 48~50℃ / 37~38℃ 10 hours; after 20 hours of baking at 52~54 / 38℃, it...

Abstract

The invention relates to a cured tobacco curing process capable of effectively reducing ash stuck on tobacco leaves. The process is divided into three specific stages, namely a yellowing stage, a color fixing stage and a vein drying stage, wherein the yellowing stage comprises the steps of raising the wet bulb temperature to 36-37 DEG C, stabilizing the temperature, and maintaining high humidity curing for 20-30 hours; after the tobacco leaves are yellowed by 60%-70%, starting humidity elimination in advance; the color fixing stage comprises the steps of adopting slow color fixing before the temperature is below 45-46 DEG C, conducting humidity elimination frequently, and promoting the tobacco leaves to sufficiently wither; after the later color fixing stage, prolonging the time of maintaining the temperature of 54 DEG C, and achieving the purposes of improving the quality and enhancing the fragrance; the vein drying stage comprises the steps of raising the temperature for conducting curing, and ensuring all the tobacco leaves and tobacco veins are dry. The advantages of the cured tobacco curing process can be simply concluded that the high temperature is maintained and the humidity is preserved so that the tobacco leaves can be yellowed; humidity elimination is conducted in advance so that the temperature can be stabilized; the humidity is maintained at the low level and the color is fixed so that the appearance can be maintained; the time of maintaining the temperature of 54 DEG C is prolonged, and the fragrance is enhanced.

Description

technical field [0001] The invention relates to a flue-cured tobacco curing process for effectively reducing ash on tobacco leaves, and belongs to the technical field of flue-cured tobacco. Background technique [0002] As we all know, tobacco leaf curing is one of the key links in the formation of tobacco leaf quality. Only through effective curing stage can the excellent quality of tobacco leaves formed in the field be fully revealed and highlighted, which is the most important stage in the field of flue-cured tobacco technology. It is also a technical bottleneck restricting the formation of good quality tobacco leaves. [0003] Some excellent varieties (such as k326) grow well in the field, but due to improper curing operations, the proportion of curing loss is relatively large; In the rainy season, the tobacco leaves are mostly rainwater tobacco, green tobacco, etc. This kind of tobacco adopts the existing three-stage curing method, which is very easy to cause serious a...
