Description

Cigarette preparation method for maintaining stable moisture content of cut tobacco or thin slices

Technical Field

The invention belongs to the technical field of cigarette production and processing, and particularly relates to a cigarette preparation method for maintaining the moisture content of tobacco shreds or thin slices to be stable.

Background

At present, in the conventional cigarettes and the heating cigarettes at home and abroad, in order to keep the moisture content of the tobacco stable, the moisture absorption or excessive drying needs to be paid special attention in the transportation, sale and carrying processes. After the cigarette packet is assembled, disassembled and sealed, the cigarette packet is easy to absorb moisture in air with high humidity and lose water in a dry environment, so that the moisture content of the cut tobacco or the thin slices is changed greatly, and the extreme condition that the cut tobacco (traditional cigarette) or the thin slices (heated cigarette) are excessively dried or are wet or even mildewed occurs, so that the smoke is dry or the temperature is high, the smoking taste is uneven, and the mouth feel is poor during smoking.

Although the moisture-proof packaging paper can keep the moisture content of cigarettes stable to a certain degree, the consumption of single-packet cigarettes has a certain time scale due to the characteristic that cigarettes suck one by one after the cigarettes are assembled, disassembled and sealed, so that the moisture-proof and water loss prevention packaging paper has strong necessity for the moisture-proof and water loss prevention of the single-packet cigarettes.
