分组加工对配方模块主流烟气及感官质量的影响

Effects of Group Processing on Mainstream Smoke and Sensory Quality of Cigarette

[目的]系统地研究干燥模式对卷烟各模块的主流烟气及感官质量的影响。[方法]以干燥模式为着手点,设计试验,从燃烧速率、主流烟气和感官质量3个方面分析研究了干燥模式对卷烟质量的影响。[结果]试验表明,干燥模式对燃烧速率影响显著,进气流干燥的烟丝燃烧速率较薄板干燥的烟丝快,在同是薄板烘丝的条件下,KLD顺流>KLD2Z逆流>KLD逆流。干燥模式对卷烟主流烟气影响显著,对总粒相物、焦油、烟碱的影响:KLD顺流>KLD2Z逆流>KLD逆流>CTD;对CO的影响:KLD顺流>CTD>KLD2Z逆流>KLD逆流。A组感官质量排序:CTD>KLD顺流>KLD逆流>KLD2Z逆流;B组和C组感官质量排序:KLD2Z逆流>KLD顺流>KLD逆流>CTD。[结论]研究可为卷烟生产选择适宜的工艺路径,进而提高工艺对卷烟产品的贡献率提供参考依据。

[Objective] To study effects of drying model on mainstream smoke and sensory quality of each module of flue-cured tobacco.[Method] Starting from drying mode,the effects on flue-cured tobacco werc studied from aspects of combustibility,mainstream smoke and sensory quality.[Result] It shows that：drying model makes an important effect on combustibility,mainstream smoke and sensory quality.For combustibility,tobacco drying by CTD is faster than drying by KLD,under the situation of drying by KLD,the order is：KLD-forward ＞ KLD2Z-backward ＞ KLD-backward.For TPM,NFDPM,nicotine：KLD-forward ＞ KLD2Z-backward ＞ KLD backward ＞ CTD ; CO：KLD-forward ＞ CTD ＞KLD2Z-backward ＞ KLD-backward.For sensory quality,the order of A is CTD ＞ KLD-forward ＞ KLD-backward ＞ KLD2Z-backward; the order of B and C is KLD2Z-backward ＞ KLD-forward ＞ KLD-backward ＞ CTD.[Conclusion] The study selects an appropriate pathway for flue-cured tobacco production,which will provide reference basis for improving technique contribution rate to flue-cured tobacco products.
