片烟成丝模式对烟丝结构与卷制质量的影响

为优化片烟成丝工艺,提升卷烟产品物理质量稳定性,对比了传统切丝与定长切丝不同片烟成丝模式对烟丝结构、产品卷制质量及原料消耗的影响。结果表明:①与传统切丝方式相比,采用40 mm定长切丝方式,烟丝结构中>3.35 mm长丝比例降低,3.35 mm以下各区间烟丝比例增加,长丝与中短丝比例均匀性得到改善;②定长切丝方式显著提升了卷烟物理质量稳定性,单支质量超标缺陷率由5.2%降低至2.2%,单支质量标准偏差降低12%以上,烟支吸阻、硬度标准偏差也有所降低;③与传统切丝方式相比,定长切丝方式下单箱耗丝量较低,而单箱耗叶量有所增加。

Effects of Cutting Mode on Cut Tobacco Structure and Cigarette Manufacturing Quality

For optimizing strips cutting and improving the consistence of physical quality of cigarette,the results of traditional cutting and fixed-length cutting were investigated in terms of cut tobacco structure,cigarette’s manufacturing quality and tobacco consumption.The results showed that: comparing with traditional cutting,1) 40 mm fixed-length cutting decreased the proportion of long strands(> 3.35 mm in length) and increased the proportion of cut tobacco < 3.35 mm in length,and the proportion between long strands and middle-short strands was improved;2) fixed-length cutting significantly increased the stability of physical quality of cigarette,the rate of cigarette not up to the standard weight decreased from 5.2% to 2.2%,the standard deviation of individual cigarette weight reduced by more than 12%,and the standard deviations of draw resistance and hardness of cigarette also reduced to a certain degree;3) the cut tobacco consumption per 50000 cigarettes decreased,but the strips consumption per 50000 cigarettes increased.
