摘 要:通过神经网络多层感知与逐步回归分析,研究细支卷烟烟丝尺寸分布与物理指标的相关性,确定影响细支卷烟物理指标及其稳定性的烟丝尺寸分布。结果表明:(1)对细支烟物理指标影响较大的烟丝尺寸主要分布在8~3.35mm和1~2.5mm;(2)≥3.35mm尺寸烟丝对吸阻产生极显著正相关影响(P<0.01),对总通风和总通风标偏产生显著负相关影响(P<0.05),2.5~1mm尺寸烟丝对硬度产生极显著负相关影响(P<0.01)。(3)细支烟在实际生产过程中,降低超长丝(>8mm)比例,增加8~3.35mm烟丝尺寸比例,可以很好地平衡各项物理指标,提高物理质量的稳定性。

Abstract: The correlation between cut tobacco size distribution and physical indexes was studied by neural network multi-layer perceptual analysis and stepwise regression analysis, and the cut tobacco size distribution influencing the physical indexes and stability of the fine cigarette was determined. The results show that: (1)the cut tobacco size which has great influence on the physical indexes of fine cigarettes mainly distributes in the range of 8mm-3.35mm and 1mm-2.5mm; (2)The results showed that the size of cut tobacco≥3.35mm had a significant positive correlation effect on the suction resistance (P<0.01), a significant negative correlation effect on the total ventilation and the total ventilation deviation (P<0.05), and a significant negative correlation effect on the hardness of 2.5mm-1 mm cut tobacco (P<0.01). (3)It is concluded that in the actual production process of fine cigarette, reducing the proportion of filament (>8mm) and increasing the size proportion of 8-3.35mm cut tobacco can well balance various physical indicators and improve the stability of physical quality.

細支烟作为中式卷烟新品类,在国内获得了较快的发展,与常规卷烟相比,细支烟烟支细长、横截面小,卷烟单支重量减小,烟支吸阻变大,抽吸气流速度变大,导致细支烟的各项质量指标均发生了变化[1-3]。针对随之出现的烟支重量波动及吸阻稳定性差等情况,对细支烟烟丝的均匀性和卷烟质量的稳定性提出了更高的要求。目前,有关细支卷烟烟丝结构对物理指标影响的研究仍较少,通过参考常规卷烟及短支烟相关研究对细支卷烟物理质量及其稳定的提升具有参考价值。李善莲等[4]通过分析烟丝结构与卷烟端部落丝量的相关关系,在试验范围内得出影响卷烟端部落丝量相关性的烟丝结构分布。邵宁等[5]研究了不同档次卷烟烟丝结构分布对物理质量的影响,针对不同档次卷烟提出了烟丝结构优化措施。楚晗等[6]研究了基于短支卷烟物理质量稳定的烟丝尺寸优化,得出了对短支烟物理质量及其稳定性产生主要影响的烟丝尺寸分布及其相关性。……
