摘要
为解决传统"三段式"加香滚筒香料吸收率低等问题,采用数值仿真模拟技术,利用EDEM软件对加香滚筒内烟丝颗粒运动轨迹进行模拟,分别考察了导料板数量、混合段导料板高度和阻流段导料板轴向角度3个特征参数对滚筒内烟丝颗粒数量及停留时间的影响,并优化了烟丝抛撒路径;基于优化结果设计了"五段式"加香滚筒,并采用超声提取-气相色谱质谱联用法对引入的目标致香化合物薄荷醇和香茅醇进行定量分析。结果表明:(1)"五段式"滚筒与"三段式"滚筒相比,薄荷醇吸收率增幅22.56%,香茅醇吸收率增幅76.67%;改进前后各致香化合物的变异系数均在工艺质量要求的15%以内;(2)感官评价结果显示烟支嗅香浓郁,香气量充足,符合产品设计要求。该技术可为提升加香均匀性和香料吸收率提供支持。
In order to promote the flavor absorptivity of tobacco in traditional“three-section”flavoring cylinder, the movement trajectory of tobacco particles in the cylinder was numerically simulated with EDEM software. The effects of three characteristic parameters, the number of paddles, the height of paddles in mixing section and the axial angle of paddles in spoiler section, on the amount and residence time of tobacco particles in the cylinder were investigated. The projecting route of tobacco particles was optimized, and a “five-section” flavoring cylinder was designed based on the results of optimization. The introduced target aroma compounds, menthol and citronellol, were quantitatively analyzed by ultrasonic extraction-gas chromatography-mass spectroscopy(UE-GC/MS). The results showed that:1) Compared with the traditional“three-section”cylinder, the menthol and citronellol absorptivities of tobacco in“five-section”cylinder increased by 22.65% and 76.67% respectively. The coefficient of variation of the two aroma compounds before and after the improvement was lower than 15% that required by process quality. 2)The sensory evaluation indicated that tested cigarettes featured rich olfactory aroma and adequate aroma quantity and met their design requirements. This technology provides a support for promoting flavoring uniformity and flavor absorptivity.
