滤棒对卷烟贮存期间含水率的影响

The effects of filter rod on cigarette moisture content during storage period

通过对两个牌号烟丝、6个不同品种滤棒进行含水率数据和样品质量变化数据的测试,分析滤棒对卷烟含水率的影响.结果表明:滤棒吸湿能力和初始含水率会影响其与烟丝含水率间的平衡关系,进而影响卷烟贮存期间含水率的变化.如果滤棒初始含水率远低于平衡含水率,则表现为吸湿,引起卷烟成品含水率下降;反之则表现为解湿,引起卷烟成品含水率上升.三元空腔纳米颗粒双沟槽复合滤棒和活性碳生物滤棒具有较强的吸湿能力,在卷烟贮存期间会从烟丝中吸收水分,从而导致卷烟含水率显著降低,下降幅度分别为0.234%和0.643%.

According to the data of testing moisture content,as well as the processing data of sample quality change of two types of shredded tobacco’s and six different varieties of filter rods’,the effects of cigarette shredded tobacco moisture content by filter rod were analyzed.It turned out that the moisture absorption and initial moisture content of filter rods could affect the equilibrium relationship between the filter rod and shred-ded tobacco moisture content and further changes in moisture content during storage period.If the initial mois-ture content of filter rods was lower than the equilibrium moisture content,it showed the performance of mois-ture absorption and the moisture content of finished cigarette dropped;Conversely,it showed the performance of moisture desorption,and the moisture content of finished cigarette rose.The activated carbon-biological filter rod and ternary double-grooved cavity nanoparticles composite filter rods had strong moisture absorption,it would absorb moisture from the shredded tobacco,resulting in significant reduction in the moisture content of cigarette,a decrease respectively 0.234% and 0.634%.
