为研究经过二次切丝工艺制备的近似烟丝形态的微波膨胀梗丝在烟丝中的掺配效果,掌握微波膨胀梗丝在产品中的应用特性,参照气流干燥梗丝工艺掺配流程,以微波膨胀梗丝的掺配样品为研究对象,采用3种均匀度测定方法(特征值与混合均匀度法、主流烟气移动极差法及烟支密度标准偏差法)对微波膨胀梗丝在烟支中的掺配均匀性进行了评价,并与气流干燥梗丝掺配样品进行了对比.结果表明:①通过滚筒掺配、往复式布料方式可有效保证微波膨胀梗丝在产品应用中掺配均匀性的要求,13%、23%、33%比例下实验样品的混合均匀度均高于96%;②同掺配比例下,两种梗丝掺配样品的烟支密度无显著差异,说明微波膨胀梗丝在烟丝中的掺配均匀性与气流干燥梗丝相当;③与气流干燥梗丝相比,微波膨胀梗丝掺配样品主流烟气中焦油、一氧化碳的波动均有降低趋势,烟碱波动与气流干燥梗丝相当,说明微波膨胀梗丝在烟丝中的混合均匀度比气流干燥梗丝更优.

In order to study the blending effect of microwave expanded cut stems (which were prepared by secondary cutting and similar to cut tobacco in shape) in cut tobacco and grasp their application characteristics in tobacco products, the blending uniformity in cigarette was comprehensively evaluated with three methods, characteristic value and blending uniformity method, mainstream cigarette smoke moving range method, cigarette density standard deviation method, by referring to the blending process of pneumatically dried cut stem. The blending uniformity of microwave expanded cut stem was compared with that of pneumatically dried cut stem. The results showed that: 1) Blending in cylinder and reciprocating spreading effectively promoted the blending uniformity of microwave expanded cut stems in cigarette, and the blending uniformity of experimental samples was all higher than 96% at the blending ratios of 13%, 23% and 33%. 2) At the same blending ratio, there was no significant density difference between cigarettes blended with microwave expanded cut stems or pneumatically dried cut stems, it indicated that the blending uniformity of microwave expanded cut stems in cigarette was comparable to that of pneumatically dried cut stems. 3) The fluctuation ranges of tar and CO deliveries in the mainstream smoke of cigarettes blended with microwave expanded cut stems were narrower than those with pneumatically dried cut stems, while their nicotine delivery fluctuation ranges were similar, it indicated that the blending uniformity of microwave expanded cut stems in cigarette was better than that of pneumatically dried cut stems.
