烟用材料对手工包装卷烟含水率的影响研究

Research on the Influence of Tobacco Materials on the Moisture Content of Hand-packaged Cigarette

为考查烟用材料对手工包装卷烟含水率的影响规律,建立了烟包各组分含水率与相对湿度关系模型,分析了烟用材料对成品烟丝含水率的理论影响,并利用小盒进行了实际验证。结果表明,①不同组分的水分散失速率有一定差异,达到平衡的时间由快到慢依次为滤棒>卷烟纸>接装纸>小盒>烟丝;②各组分的平衡含水率存在牌号间差异,其中牌号A、B、C烟丝在相对湿度60%条件下的平衡含水率分别为11.84%,12.08%,12.12%,在各牌号烟丝及材料含水率标准设计时,应重点考虑其与相对湿度的匹配性;③相对湿度波动对平衡含水率的影响存在组分间差异,其中相对湿度由45%升高至75%时,牌号A的烟丝、小盒、滤棒、卷烟纸、接装纸的含水率分别对应变化10.00%,2.19%,1.76%,2.50%,2.00%,在卷烟生产时,应强化各生产区域尤其是贮丝、风送、卷包过程的环境湿度稳定性保障;④烟用材料在烟包内的质量占比越大,对成品烟丝含水率的影响越大,其中手工包装卷烟小盒含水率每波动1.00%,牌号A、B、C的成品烟丝含水率对应变化高达1.09%,1.53%,1.66%,由于手工包装卷烟小盒重量占比远高于常规卷烟,在包装生产前,应加强小盒含水率的匹配性与稳定性保障,以提高包装后成品烟丝含水率的稳定性。

In order to research the influence of tobacco materials on moisture content of Hand-packaged cigarette,the relationship model between moisture content of different components and relative humidity was established,and the theoretical effect of tobacco materials on moisture content of cut tobacco was analyzed,and the actual effect was verified by cigarette box.The results showed that:①The water loss rate of different components were different,the order from fast to slow was filter rod>cigarette paper>tipping paper>cigarette box>cut tobacco.②The moisture content of different components were different among brands.The moisture content of brand A,B and C cut tobacco under relative humidity of 60%were 11.84%,12.08%and 12.12%.In the process design,the moisture standards of cut tobacco and materials should be formulated on the basis of the influence law of relative humidity.③The effect of relative humidity fluctuation on the moisture content were different among the components.When the relative humidity increased from 45%to 75%,the moisture contents of cut tobacco,cigarettes box,filter rod,cigarette paper and tipping paper of brand A changed by 10.00%,2.19%,1.76%,2.50%and 2.00%.In the production of cigarettes,the stability of environmental humidity in every production area should be strengthened especially in the process of storage,air delivery and package.④the impact of on the moisture content of the finished cut tobacco increased with the weight proportion of tobacco materials.The moisture content of the cigarette box of the Hand-packaged cigarette fluctuates by 1.00%,and the moisture content of the finished cut tobacco of brands A,B and C changes as high as 1.09%,1.53%and 1.66%.Since the weight proportion of the Hand-packaged cigarette box was much higher than that of the conventional cigarette,the matching and stability guarantee of the moisture content of the cigarette box should be strengthened before packaging production to improve the stability of the moisture content of the finished cut tobacco after packaging.
