基于短支卷烟物理质量稳定的烟丝尺寸优化设计

Optimization of the cut tobacco size based on physical quality stabilizing of short cigarettes

利用相关性分析和回归分析法研究烟丝尺寸分布与短支卷烟主要物理指标的相关关系,分析影响短支卷烟物理质量及其稳定性的具体烟丝尺寸分布.结果表明:①对短支卷烟物理质量及其稳定性产生主要影响的烟丝尺寸分布为 X1 (>7.00mm )、 X3 ( 3.35~5.00mm )、X5 ( 1.00~2.50mm )、 X6 (<1.00mm );②其中 X1 层烟丝与卷烟重量标偏呈线性正相关, X5 层烟丝与吸阻、硬度及其标偏呈线性负相关, X3 层、 X6 层烟丝与端部落丝量和含末率分别呈线性负相关和正相关.在短支卷烟实际生产中,可以针对波动较大的物理指标,通过适当增加短丝和中长烟丝的比例,减少超长烟丝和碎丝比例,达到提升短支卷烟物理质量及其稳定性的目的.

Correlation analysis and regression analysis were used to study the correlation between cut tobacco size and main physical indexes of short cigarettes, and analyzed the specific tobacco sizes that affect the physical quality and stability of short cigarettes. Results:① the sizes of cut tobacco which had a main influence on physical quality and stability of short cigarettes were layers X1 (>7.00 mm), X3 (3.35~5.00 mm), X5 (1.00~ 2.50 mm ), and X6 (<1.00 mm);② layer X1 was linearly positively correlated with the standard deviation of weight, layer X5 was linearly negatively correlated with the draw resistance, hardness and their standard deviation, there was a respectively linear negative correlation and linear positive correlation between the layer X3 and the layer X6 with the end of the amount of silk and the end of containing rate. In actual production, the physical quality of the short cigarettes and its stability could be improved by increasing the short and medium-long cut tobacco, decreasing the long and ultra-short cut tobacco according to the physical indexes with large fluctuations.
