Embodiment 1

[0029] Fermentation tests on B3F (Bijie, Guizhou) and C3L (Xingyi, Guizhou) tobacco leaves:

[0030] 1) Gradually increase the temperature of the cigarette package to 50°C. During the temperature increase process, the ambient humidity is 55%, and the duration of the entire temperature increase process is 5 days;

[0031] 2) Keep the cigarette package at 50°C and 55% ambient humidity for 6 days;

[0032] 3) Gradually lower the temperature of the cigarette pack to 30-33°C, and the duration of the entire cooling process is 4.5 days.

[0033] After combining the fermentation results of the two tobacco leaves, the specific evaluation results are shown in Table 1.

Embodiment 2

[0035] Fermentation tests on B3F (Bijie, Guizhou) and C3L (Xingyi, Guizhou) tobacco leaves:

[0036] 1) Gradually increase the temperature of the cigarette package to 50°C. During the temperature increase process, the ambient humidity is 65%, and the duration of the entire temperature increase process is 4 days;

[0037] 2) Keep the cigarette package at 50°C and 65% ambient humidity for 5 days;

[0038] 3) Gradually lower the temperature of the cigarette pack to 30-33°C, and the duration of the entire cooling process is 4.5 days.

[0039] After combining the fermentation results of the two tobacco leaves, the specific evaluation results are shown in Table 1.

Embodiment 3

[0041] Fermentation tests on B3F (Bijie, Guizhou) and C3L (Xingyi, Guizhou) tobacco leaves:

[0042] 1) Gradually increase the temperature of the cigarette package to 45°C. During the temperature increase process, the ambient humidity is 60%, and the duration of the entire temperature increase process is 5 days;

[0043] 2) Gradually lower the temperature of the cigarette package to 30-33°C, and the duration of the entire cooling process is 7 days.

[0044] After combining the fermentation results of the two tobacco leaves, the specific evaluation results are shown in Table 1.

Abstract

The invention relates to the field of tobacco processing, in particular to a flue-cured tobacco fermentation process. The process includes the steps of 1, intensifying, namely heating a tobacco bale gradually to 47-49 DEG C for 5-5.5 days, and controlling the ambient humidity to be 61-63% during heating; 2, mellowing, namely, cooling the tobacco bale gradually to 30-33 DEG C for 7.5-8 days, and supplying moisture moderately during cooling. The tobacco produced by the process has uniform color, significantly enhanced oily moistness, obvious fragrance, significantly reduced stimulus, comfortable taste and clear aftertaste. Compared with the traditional process, the flue-cured tobacco fermentation process has the advantages that energy consumption is decreased by 20-30% and economic benefit is significant.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a flue-cured tobacco leaf fermentation process. Background technique [0002] Tobacco leaf fermentation is a primary processing method for the cigarette industry to improve product quality, and it is also an extremely important link in cigarette processing. Tobacco leaves that have not been fermented have a variety of quality defects in varying degrees, such as green miscellaneous and irritating, monotonous aroma, and insufficient aroma, so they cannot be directly used to produce cigarettes. In the cigarette production process, a good fermentation process can greatly improve the quality of tobacco leaves and improve the quality of cigarettes. [0003] Tobacco leaf fermentation is mainly divided into two types: natural fermentation and artificial fermentation. Natural fermentation is to ferment the modulated tobacco leaves with the help of natural climate changes. This ferment...
