雪茄型卷烟风送及卷制过程对梗丝比例的影响

Effects of pneumatic tobacco feeding and cigarette making on cut stem proportion in cigar type cigarette production

为了解雪茄型卷烟气力配丝(即风送)及卷制前后烟丝构成的变化情况,以某牌号雪茄型卷烟烟丝为对象研究了风送和卷制过程对烟丝中梗丝比例的影响。结果表明:①风送后的该牌号雪茄型卷烟烟丝中梗丝比例较风送前平均提高1.4百分点,平均变化率为7.4%;卷制后的梗丝比例较卷制前总体呈现升高的趋势,平均变化率为2.05%;经风送和卷制后的烟丝中梗丝比例的平均变化率为9.60%,以风送过程的影响作用为主。②各取样点梗丝比例的方差差异不显著,风送与卷制过程只影响梗丝比例的高低,不影响其波动性。③不同机台间风送后(卷制前)和卷制后的梗丝比例差异程度均不同,卷制前的梗丝比例差异会在卷烟中表现出来,且采用相同机型卷接机组有利于降低不同机台间的差异性。

In order to investigate the variations of cut tobacco composition affected by pneumatic tobacco feeding and cigarette making of cigar type cigarette production, the effects of pneumatic tobacco feeding and cigarette making process on the proportion of cut stem in cut tobacco of a cigar type cigarette brand were studied. The results showed that: 1) The proportion of cut stem in cut tobacco increased by 1.4 percentage points after pneumatic feeding, and the average variation rate was 7.4%. The proportion of cut stem raised generally after cigarette making with the average variation rate of 2.05%. The average variation rate of cut stem proportion was 9.60% after pneumatic feeding and cigarette making, mainly contributed by the former. 2) No significant difference in the variance of cut stem proportion was found between different sampling points, therefore pneumatic feeding and cigarette making process affected the proportion of cut stem, not its fluctuation. 3) The degree of difference in cut stem proportion after pneumatic feeding and cigarette making differed between cigarette makers, particularly between the cigarette makers of different types. The difference of cut stem proportion before cigarette making would be reflected by the finished cigarettes.
