烘丝机设备参数与叶丝质量关系研究—以红河卷烟厂某牌号叶丝为例

The Study on the Relationship between the Cut Tobacco Drier Equipment Parameters and the Tobacco Leaf Silk Quality—Based on the Data of a Brand Leaf Silk in Honghe Cigarette Factory

烘丝机设备参数直接影响着烘后叶丝物理指标、卷烟后序加工质量及卷烟内在品质。本文采用回归设计试验,系统探讨了红河某牌号烟丝生丝含水率、工艺流量、HT蒸湿压力、烘丝机筒壁温度、热风温度、排潮风门开度6个设备参数与烘后叶丝的含水率、填充值、整丝率、碎丝率、化学成分等质量特性的关系,建立了烘丝机设备参数与烘后叶丝含水率、填充值、叶丝绿原酸和糖碱比的统计模型。结果表明:为保障烘后叶丝含水率均匀一致,应重点关注生丝含水率的波动;为提高叶丝填充值,可适当降低生丝含水率,同时增加HT蒸汽压力和筒壁温度。

Cut tobacco drier equipment parameters directly affect the leaf silk physical indicators, the quality of cigarette after drying processing and cigarette inner quality. Using regression design experiment, this paper systematically discusses the relationship of the tobacco moisture content, process flow, steam pressure of HT, the temperature of hot-air and cylinder wall, the opening of the exhausted valve among the tobacco moisture contents, filling power, the proportion of long strands, the proportion of small strands, and chemical component. Statistical model of cut tobacco drier equipment parameters and silk moisture content after drying, filling power, leaf silk chlorogenic acid, and ratios of total sugar to betaine is established. Results show that in order to ensure silk moisture content after drying uniformity, we should focus on the fluctuation of raw silk moisture content;in order to improve the leaf silk filling power, we should reduce the moisture content of raw silk appropriately and increase the steam pressure of HT and the temperature of cylinder wall at the same time.
