烟丝含水率对卷烟落锥及烟气成分的影响

目的]了解烟丝含水率对卷烟落锥及烟气成分的影响。方法]研究了部分贵烟牌号在不同平衡湿度条件下的卷烟落锥及烟气成分情况。结果]卷烟烟丝含水率随平衡湿度增加而逐渐增加,卷烟的总粒相物、烟气烟碱、焦油含量变化不明显,卷烟抽吸口数、一氧化碳量呈现出相同的增加趋势,当烟丝水分条件一定,各烟气成分间并无显著的关联性;卷烟含水率升高,卷烟落锥数量明显减少,不同含水率条件对卷烟落锥的影响要大于不同卷烟之间造成的影响,不同卷烟之间的落锥个数存在显著差异,卷烟在50%与60%水分条件下落锥个数无明显差异,其余含水率条件下卷烟的落锥个数存在显著差异。结论]不同烟丝含水率及烟丝结构对卷烟落锥量有明显影响。

Influence of Moisture Content in Cut Tobacco on Cigarette Fire-drop and Smoke Components

Objective] In order to find the disparity of cigarettes fire-drop conditions and smoke components with different moisture contents.Method] The changes of moisture content in cigarettes of guiyan brands of different relative humidity were studied.Result] As the circumstances relative humidity increased,the moisture content in cut tobacco increased,the total particulate matter,nicotine and tar contents in cigarette smoke were less obvious,while the numbers of smoke and the CO increased at the same time.in addition,no correlation was obvious between matters of smoke,as the moisture content in cut tobacco at a certain level.The cigarettes fire-drop numbers decreased slightly while the increase of moisture content in cut tobacco,which appears to influence moisture content more deeply than brands to brands.otherwise,there were significant difference in each brand from different moisture content in cut tobacco of the fire-drop numbers,except for the moisture content at 50% and 60% levels.Conclusion]Different moisture contents and structure of tobacco proportion had a significant effect on cigarette fire-drop numbers.
