Embodiment 1

[0024] Weigh 15g SiO 2 , 5g Al 2 o 3 (SiO 2 with Al 2 o 3 It is a powder sample, the particle size is 10um, 15um respectively) to 100g mass fraction of 20wt% Ca(OH) 2 The solution was stirred at room temperature for 10 min, then the mixed solution was added into a hydrothermal reaction kettle, and reacted at 200° C. for 15 h. The samples were washed to remove impurities and then vacuum-dried to obtain humidity-regulating materials. Fill the humidity-regulating material into the non-woven fabric after being saturated with water and put it in the center of the box when the cigarettes are packed. The quality of the humidity regulator is 3% of the mass of the cigarettes. Sampling was carried out every 6 months, and the moisture content and 5-hydroxymethylfurfural content of the tobacco were analyzed by multi-point sampling method.

Embodiment 2

[0026] Weigh 10g SiO 2 , 10g Al 2 o 3 (SiO 2 with Al 2 o 3 It is a powder sample, the particle size is 10um, 15um respectively) to 100g mass fraction of 20wt% Ca(OH) 2 The solution was stirred at room temperature for 10 min, then the mixed solution was added into a hydrothermal reaction kettle, and reacted at 200° C. for 15 h. The samples were washed to remove impurities and then vacuum-dried to obtain humidity-regulating materials. Fill the humidity regulating material into the non-woven fabric after being saturated with water and put it in the center of the box when the cigarettes are packed. The quality of the humidity regulator is 3% of the weight of the cigarettes. Sampling was carried out every 6 months, and the moisture content and 5-hydroxymethylfurfural content of the tobacco were analyzed by multi-point sampling method.

Embodiment 3

[0028] Weigh 5g SiO 2 , 7g Al 2 o 3 (SiO 2 with Al 2 o 3 It is a powder sample, the particle size is 10um, 15um respectively) to 100g mass fraction of 20wt% Ca(OH) 2 The solution was stirred at room temperature for 10 min, then the mixed solution was added into a hydrothermal reaction kettle, and reacted at 200° C. for 15 h. The samples were washed to remove impurities and then vacuum-dried to obtain humidity-regulating materials. Fill the humidity-regulating material into the non-woven fabric after being saturated with water and put it in the center of the box when the cigarettes are packed. The quality of the humidity regulator is 3% of the mass of the cigarettes. Sampling was carried out every 6 months, and the moisture content and 5-hydroxymethylfurfural content of the tobacco were analyzed by multi-point sampling method.

Abstract

The invention relates to a method for adjusting the moisture content of boxed lamina, which comprises the following steps of: putting a humidity regulator into a box when the lamina is boxed, and adjusting the alcoholization progress of the lamina by adjusting the moisture content of the lamina, so that the moisture content in the lamina alcoholization process can be effectively adjusted and controlled, the lamina alcoholization progress is balanced, the alcoholization period is shortened, the subsequent processing performance is improved and crushing consumption is reduced. The method is low in cost, easy and convenient to operate, easy to implement and suitable for natural alcoholization storage of the tobacco lamina in areas with low external environment air moisture content.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf maintenance, and in particular relates to a method for adjusting the moisture content of box-packed sheet tobacco. Background technique [0002] During the natural aging process of tobacco leaves, the moisture content has an important influence on the aging progress of tobacco leaves. Studies have shown that the most favorable mellowing moisture content for flue-cured tobacco flakes is 13-14%. Based on anti-mildew requirements, the moisture content of the tobacco after threshing and re-baking is set at 11-13%, and the box is covered with a plastic film bag. In the north where the annual average humidity is low, this package can prevent the entry of external moisture. But it cannot prevent the loss of internal moisture. During the natural aging process, the hydrophilic colloidal substances in the tobacco leaves are decomposed, and the water bound by the colloidal substances is released, whic...
