两段式烘丝控制模式对中支卷烟烟丝理化特性及感官质量的影响

为研究两段式滚筒烘丝机不同控制模式对中支卷烟品质的影响,探索了筒壁温度前高后低、前低后高变温干燥和一段式恒温干燥对烟丝理化特性及产品感官质量的影响规律。结果表明:①滚筒变温干燥模式均能够提高叶丝长丝率、整丝率和填充性能,而恒温干燥模式则有利于提升叶丝结构的分布均匀性;②不同干燥模式对叶丝挥发性香味成分的形成与积累影响较小,采用125 ℃/145 ℃变温干燥和135 ℃一段式恒温干燥低强度处理模式更有利于提升叶丝化学成分的协调性和香味成分的积累量;③125 ℃/145 ℃变温和135 ℃一段式恒温干燥低强度处理模式均有利于彰显“清甜香”品类卷烟产品的感官质量,兼顾干燥叶丝的理化特性和卷烟感官质量,135 ℃一段式恒温干燥模式更适宜“云烟”品牌中支卷烟的加工生产。 

Two-section cylinder dryer's control mode on cut tobacco properties and sensory quality of demi-slim cigarettes

In order to investigate the effects of different control modes for two-section cylinder dryer and the resulted quality of demi-slim cigarettes, two varying temperature drying modes (a high-to-low and low-to-high cylinder wall temperature, in the direction of tobacco flowing) and a constant wall temperature mode were evaluated on the physicochemical properties of cut leaf strips and the sensory quality of the cigarettes. The results showed that: 1) The two varying temperature drying modes promoted longer strand proportion, integral strand proportion and the filling power of cut strips, and the constant temperature drying mode was beneficial to the uniformity of cut strip structure. 2) The generation and accumulation of volatile aroma components in the dried cut strips were influenced by the drying modes slightly. The dual-temperature drying mode at 125 ℃/145 ℃ and the constant temperature drying mode at 135 ℃ resulted in a lower processing intensity and more conducive to promote the chemical constituent harmony and the accumulation of aroma components in the finished cut strips. 3) Both the dual-temperature drying mode at 125 ℃/145 ℃ and the constant temperature drying mode at 135 ℃ with a lower processing intensity were helpful to demonstrate the fresh-sweetness scent sensory quality of the cigarettes, with improving physicochemical properties of dried cut strips and the overall sensory quality of the cigarettes. The constant temperature drying mode at 135 ℃ was more suitable for the processing and production of demi-slim cigarettes of Yunyan brand.
