Summary of the invention:

The objective of the invention is to overcome the deficiency that prior art can not be adjusted redrying piece cigarette moisture content according to the tobacco leaf position, and the situation that lacks the method for effective shortening nature digestion time at present, and provide a kind of by improving the method that redrying piece cigarette moisture content shortens the tobacco natural digestion time.

Of the present invention by improving the method that redrying piece cigarette moisture content shortens the tobacco natural digestion time, the improvement on existing method basis forms.The present invention shortens the tobacco natural digestion time by the suitable redrying piece cigarette water content that improves middle part cigarette and upper tobacco leaf under certain ageing environmental condition, be specially:

A. the natural environment temperature of ageing is lower than 20 ℃, and relative humidity is lower than 65%, and monthly relative humidity is no more than 75%; Or the environment temperature of Artificial Control ageing is lower than 20 ℃, and relative humidity is lower than 65%;

B. controlling tobacco redrying sheet middle part cigarette water content is 12.5-13.2%, and the storage natural alcoholization time is 18 months;

C. controlling tobacco redrying sheet upper smoke water content is 12.8-13.5%, and the storage natural alcoholization time is 21.

The same prior art of daily management of the method for control strip cigarette water content and natural ageing process among the present invention.

The present invention compared with prior art, having in the ageing process tobacco leaf does not have and goes mouldy, the quality of sheet cigarette changes obviously, sensory evaluating smoking's quality obviously improves, natural digestion time significantly shortens, and greatly reduces the advantage of tobacco leaf storage cost.

The specific embodiment:

The present invention implements in Yuxi Hongta Group.Specific as follows:

1, the setting of redrying piece cigarette moisture

1.1 the redrying piece cigarette moisture of middle part cigarette and upper smoke is set at 12.2-12.7%, 12.7%-13.2%, 13.2%-13.7%;
