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. [ABSTRACT FROM AUTHOR] |
