Abstract: In order to explore the law of broken cut tobacco during processing,different widths and lengths of cut tobacco were designed,and the structural changes of cut tobacco before and after the key processing links such as roller,fluidization and mechanical transportation were studied.The results showed that with the process of cut tobacco processing,all specifications of cut tobacco were broken continuously,the characteristic size of cut tobacco decreased,and the degree of breakage increased,mainly the mass fraction of cut tobacco with longer sizes of>7.10 mm and 4.50—7.10 mm decreased significantly,and the mass fraction of cut tobacco with<2.00 mm increased continuously.The difference of cut tobacco quality fraction of 3.35—4.50 mm was the largest among different treatments.The change rate of cut tobacco mass fraction in the process of drum processing was large,among which the process of drum drying was the largest,followed by the processes of vibration conveying,lifting conveying after drying and wind conveying,and the processes of wind cleaning and lifting before drying were smaller.After the whole processing,the characteristic size variation of 1.0 mm width cut tobacco,1.0 mm width apocoptic cut tobacco,0.8 mm width cut tobacco and 0.8 mm width apocoptic cut tobacco reached 1.86 mm,1.09 mm,1.65 mm and 1.08 mm,respectively,and the crushing degree reached 33.51%,26.35%,33.39% and 27.43%,respectively.The cut tobacco with larger feature size of>7.10 mm and 4.50—7.10 mm and narrower cut tobacco width is more likely to be broken during processing,so the quality change law of specific size of cut tobacco should be paid attention to according to the needs of processing,and the structure regulation and process optimization of tobacco should be carried out within the scope of raw material consumption.

摘要: 为探索烟丝在加工过程中的破碎规律,设计不同切丝宽度和尺寸的烟丝,研究滚筒、流态化、机械输送等关键加工环节前后烟丝的结构变化规律。结果表明,随着烟丝加工进行,各规格烟丝不断破碎,烟丝的特征尺寸降低,破碎度升高,主要表现在>7.10 mm和4.50~7.10 mm等尺寸较长的烟丝质量分数不断降低,<2.00 mm的烟丝质量分数不断升高,不同处理间3.35~4.50 mm的烟丝质量分数变化差异最大。滚筒加工过程中烟丝质量分数的变化率整体较大,其中滚筒干燥过程最大,其次是振动输送、干燥后的提升输送和风送过程,风选和干燥前的提升等过程较小。加工后1.0 mm宽度烟丝、1.0 mm宽度断丝的烟丝、0.8 mm 宽度烟丝和0.8 mm 宽度断丝的烟丝特征尺寸变幅分别达到1.86 mm、1.09 mm、1.65 mm 和1.08 mm,其破碎度分别达到33.51%、26.35%、33.39% 和27.43%。综上,>7.10 mm 和4.50~7.10 mm等特征尺寸较大及同一断丝或未断丝处理下宽度较窄的烟丝在加工过程中更易破碎,应根据加工的需求,关注特定尺寸的烟丝质量变化规律,在原料消耗允许的范围内,开展烟丝结构调控和工艺优化。
