Alcoholization and mildew prevention method for tobacco leaves

Abstract

The invention discloses an alcoholization and mildew prevention method for tobacco leaves. The alcoholization and mildew prevention method for the tobacco leaves comprises the following steps: sealinga tobacco box / tobacco stack by films, introducing one or more gases of nitrogen, ozone or carbon dioxide, reducing the oxygen content in the tobacco box / tobacco stack to be below 2% , and carrying out treatment for 5 to 10 days; then opening the tobacco box / tobacco stack, putting into an anti-mildew curing agent, arranging temperature-humidity collecting equipment, and oxygen-content measuring equipment; monitoring the temperature and humidity and oxygen content of the tobacco box / tobacco stack, adjusting the use amount of the anti-mildew curing agent, and keeping the oxygen content at 6 to 12%, the humidity at 50 to 65%, the temperature at 20 to 28 DEG C for more than 40 days and the like. The technology of the invention can be better applied to mildewproof maintenance of the tobacco leaves in the alcoholification period, and the operation is good under the conditions that the oxygen content is 6 to 12%, the humidity is 50 to 65% and the temperature is 20 to 28 DEG C, and the oxygenand humidity reduction speeds are moderate, so that tobacco leaf products are good in grade, and meet requirements of various technical indexes, furthermore, the cost and use amount are lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco storage, in particular to an anti-mold method used in the aging stage of tobacco leaves. Background technique [0002] The original tobacco harvested in that year has defects of varying degrees in its internal quality, such as heavy green miscellaneous gas, strong irritation, rough smoke, and smoke aroma covered by miscellaneous gas, especially the low-grade tobacco leaves are bitter, spicy and astringent. Such tobacco leaves cannot be directly used to make cigarettes, and must be properly alcoholized. Through alcoholization, the color of tobacco leaves is more uniform and properly deepened, green miscellaneous gas and irritation are greatly reduced, aroma substances are increased, and the taste is mellow. Therefore, fermentation and alcoholization is an important link for the cigarette industry to further improve the quality of tobacco leaves. [0003] Natural aging is to stack the tobacco leav...

AI Technical Summary

Problems solved by technology

The natural aging effect is better, but there are also shortcomings. The main shortcomings are: first, because the tobacco leaves are rich in nutrients and in close contact with the external environment for a long time, the tobacco leaves are prone to insects; 1. The humidity changes greatly, and the tobacco leaves are prone to mildew; the third is that because the tobacco leaves are in contact with excessive air for a long time, the color of the tobacco leaves is easy to turn brown and darken, so the natural aging time should not be too long, generally not more than 3 years

Natural alcoholization causes serious losses to tobacco leaves due to the existence of insects, mildew, etc. On the one hand, it is known that the loss of tobacco leaves after alcoholization reaches 0.8%, and the direct economic loss caused by a medium-sized cigarette factory in one year can reach more than 20 million yuan

On the other hand, it also seriously affects the internal and external quality of tobacco leaves, and affects the quality of tobacco leaf deep-processing products.

[0004] At present, the application of the sealed ultra-low oxygen method mainly uses iron-based oxygen absorbers, but the cost of iron-based oxygen absorbers is high, the oxygen is reduced too quickly, and the humidity is reduced too slowly. The existing curing agents are generally lower than 2% in the post-alcoholization stage. Use under oxygen conditions
