摘要
以烟草样本中糖碱比与钾含量的乘积作为特性值,基于卷烟制丝过程样本特性值正态分布检验和烟草混合均匀度计算,通过控制图、过程能力指数及烟草混合能力分析,探究各工序烟草质量稳定性及其变化规律。结果表明:松散回潮工序烟草混合均匀度67.04%,变异系数达到32.96%,其混合均匀性较差;预混对烟草混合均匀性的提升贡献最大,一级加料预混后方差降低指数17.59,烟草混合均匀度达到94.30%;松散回潮和一级加料预混工序中烟草物料加工质量稳定性欠佳,后续4个工序烟草物料混合均匀度>95%,过程能力指数C_(P)值均接近2.0,加工质量稳定性较优。根据该结果可在卷烟制丝过程采用增加烟块切刀次数、增加预混柜等方式改善物料的混合均匀性和质量稳定性。
The product of sugar-base ratio and potassium content in tobacco samples was used as the property value,and the normal distribution test of sample property value in cigarette making process and the calculation of tobacco mixing uniformity were conducted.Through the analysis of control chart,process capability index and tobacco mixing ability,the quality stability and variation law of tobacco in each process were explored.The results showed that the mixing uniformity of tobacco in loose moisture regain process was 67.04%,the coefficient of variation was 32.96%,and the mixing uniformity was poor.Premixing contributed the most to the improvement of tobacco mixing uniformity,with the variance reduction index of 17.59 after first-order feeding premixing,and the tobacco mixing uniformity reached 94.30%.The processing quality stability of tobacco materials in loose moisture regain and primary feeding premixing process was poor.The mixing uniformity of tobacco materials in the subsequent four processes was more than 95%,and the process capability index C_(P)value was close to 2.0.The processing quality stability was better.According to the results,the mixing uniformity and quality stability of the material could be improved by increasing the number of cigarette cutters and increasing the premixed cabinet in the cigarette making process.
