为合理控制烟丝中梗签粒度及其含量,减少烟支刺破概率,通过大量收集刺破不同圆周烟支的梗签,分析刺破烟支梗签粒度分布规律。结果表明:(1)卷制过程中较大尺寸梗签基本能被卷烟机剔除;(2)宽度小于0.7 mm或长度小于1.0 mm的细梗签和梗粒造成烟支刺破的概率较小;(3)常规烟、中支烟、细支烟刺破烟支梗签的宽度主要集中在1.0 mm～3.0 mm之间,占80%以上,平均宽度分别为2.12 mm、1.74 mm和1.69 mm,约为对应烟丝宽度的2倍;长度分别主要集中在6 mm～9 mm、4 mm～7 mm和3 mm～6 mm范围内,占70%以上,平均长度为分别为7.39 mm、5.89 mm和5.12 mm,与对应烟支直径基本相当;(4)为减少刺破概率,叶中含梗应重点控制直径1.0 mm以上含梗比例,提高切丝宽度的均匀性,常规、中支、细支卷烟应分别重点控制长度>6 mm、>4 mm、>3 mm的梗签。
Abstract：In order to reasonably control the particle size and content of stalks in shredded tobacco and reduce the probability of puncturing a cigarette,a large number of cigarette-puncturing slivers in cigarette with different circumferences were collected to analyze the particle size distribution of cigarette-puncturing slivers.The results show that:(1) Large-sized stalks can basically be removed by the cigarette machine during the rolling process;(2) Thin stalks and stalk particles with a width less than 0.7 mm or a length less than 1.0 mm have a lower probability of puncturing a cigarette (3) The width of the cigarette-puncturing slivers of conventional cigarettes,medium cigarettes and thin cigarettes is mainly concentrated between 1.0 mm and 3 mm,accounting for more than 80%,and the average widths are 2.12 mm,1.74 mm and 1.69 mm,respectively,which are approximately 2 times the width of the corresponding tobacco shred;(4) The length of the cigarette-puncturing slivers of conventional cigarettes,medium cigarettes and thin cigarettes is mainly concentrated in the range of 6 mm～9 mm,4 mm～7 mm,and 3 mm～6 mm,accounting for more than 70%,and the average length is 7.39 mm,5.89 mm and 5.12 mm,respectively,which are basically equal to the diameter of corresponding cigarette;(5) In order to reduce the probability of shredded tobacco puncturing,the proportion of stalks with a diameter of 1.0mm or more contained in leaves should be controlled,and the uniformity of tobacco shred tobacco width should be improved.Stalk with lengths of >6 mm,> 4 mm,>3 mm should be mainly controlled for regular,medium,and thin cigarettes,respectively.
