Tobacco leaf treatment method with advantage of prolonging mellowing period of laminae

Abstract

The invention provides a tobacco leaf treatment method with the advantage of prolonging the mellowing period of laminae. The tobacco leaf treatment method comprises the following steps: (1) conducting box-by-box treatment on laminae of which the mellowing quality reaches the standard, in a storehouse: opening smokeboxes, untying lining bags, inflating CO2 gas after vacuumizing, sealing the plastic lining bags after circulating the steps for two times to three times, finally repacking the smokeboxes, and sealing the upper openings and the lower openings of the smokeboxes; (2) transferring the sealed smokeboxes in a specific storage environment, controlling the temperature and the humidity, wherein the temperature is required to 10-20 degrees, and the humidity is required to 45%-55%, and requiring single-layer stacking when the smokeboxes are stored; and (3) unsealing the smokeboxes and the lining bags in 7-10 days before production of the batch of laminae, and gradually rising the environment temperature to 30-35 degrees in 1-2 days and increasing the humidity to 65%-70%. The tobacco leaf treatment method has the advantages that the cigarette formulating and using time of the laminae can be prolonged, the best laminae mellowing quality is ensured, the contradiction that mellowed mature laminae are urgently used is relieved, and the formulating efficiency and the using level are improved.

Description

technical field [0001] The invention relates to the technical field of storage and alcoholization of tobacco, in particular to a tobacco leaf treatment method for prolonging the aging period of laminar tobacco. Background technique [0002] Tobacco leaves are stored in the tobacco leaf warehouses of cigarette industry enterprises after a series of processing processes such as mature harvesting, baking modulation, threshing and redrying, packaging and storage. In order to remove the green miscellaneous taste of tobacco leaves and improve the quality of flavor and taste, the tobacco leaves must be mellowed as required. At present, it is mainly to use warehouse storage equipment to control environmental conditions such as temperature or humidity to carry out natural alcoholization, and the general time is 1-3 years. With the increase of aging time, the aging quality of tobacco leaves showed a trend of getting better first, reaching the peak, and then declining. The cigarette ...

AI Technical Summary

Problems solved by technology

[0003] Since 2012, the national tobacco leaf production has increased year by year, and the annual tobacco leaf purchase volume has been around 50 million tons. The rapid increase in tobacco leaf production has exceeded the growth rate of cigarette sales. Exceeding the needs of cigarette production, that is, the aging and mature tobacco leaves are too late to be put into production, and the best use period of tobacco leaf quality will be missed. This will not only lead to a decline in the quality of tobacco leaves, but also cause an increase in the metabolic consumption of tobacco leaves, which virtually increases Cigarette Production Cost

At present, there are many research results on how to accelerate the alcoholization of tobacco leaves, but there is no report on how to prolong the use period of alcoholized mature tobacco
