梗丝形态对细支卷烟加工及综合质量的影响

Effects of stem morphology on processing and comprehensive quality of slim cigarettes

为研究不同形态梗丝与叶丝的混合均匀程度,掌握不同形态梗丝对细支卷烟综合质量的影响,对比研究了丝状梗丝和片状梗丝与叶丝在加工过程中的混合均匀性,以及2种梗丝对细支卷烟物理、烟气、有害成分释放、感官、燃烧等方面及质量稳定性的影响。结果表明:与片状梗丝相比,丝状梗丝在混丝、卷制工序与叶丝的混合均匀度高,稳定性好。与掺配片状梗丝的细支卷烟相比,掺配丝状梗丝的细支卷烟物理质量稳定性好,但单支重量、吸阻稍大,可能与丝状梗丝结构偏小,长丝率低有关;掺配丝状梗丝的细支卷烟烟气指标更稳定,卷烟危害指数较低,感官质量稍好,抽吸口数和烟气烟碱较高;掺配丝状梗丝的细支卷烟具有更好的燃烧稳定性,且卷烟抽吸过程中的燃烧温度低于掺配片状梗丝细支卷烟18℃左右。

In order to study the blending effect of different stem morphology with leaf silk and understand the influence of different stem morphology on the comprehensive quality of slim cigarette,the mixing uniformity of filamentary and flake stems with leaf silk in processing were compared.Moreover,the influence of two kinds of stems on the quality stability of cigarette physical,smoke,sensory and combustion were investigated.The results showed that,compared with the flake stem,filamentary stem blending with leaf silk had higher mixing uniformity and good stability in the process of mixed silk and rolling.The physical quality of slim cigarettes blended with filamentary stem was better,but the single weight and the resistance were bigger.This may be related to the filamentary structure and filament ratio.The smoke index of the slim cigarettes blended with filamentary stem had better stability and the cigarette damage index was lower.The sensory quality was slightly better,and the number of the suction port and the smoke nicotine were higher.The slim cigarette blending with filamentary stem had better combustion stability and could reduce the combustion temperature 18 ℃ during slim cigarette aspiration.
