打叶复烤成品片烟质量稳定性的色差法评价

Application of Chromatic Aberration Method in Quality Consistency Evaluation of Finished Strips After Threshing and Redrying

摘要: 为考察色差法评价打叶复烤成品片烟质量的稳定性,在叶片复烤机出口采集了云烟87 BBSF模块复烤片烟,利用色差仪测定样品的 L^*(明度值), a^*(红度值), b^*(黄度值),对数据结果进行正态性检验,构建均值-极差图,并计算过程能力指数(Cp)。结果表明:云烟87 BBSF模块复烤片烟 L^*, a^*, b^*值的过程能力指数均满足1.33≥ C_p>1.00,说明复烤成品片烟质量的稳定性较好。同时,云烟87BBSF模块复烤片烟的混合均匀度为85.72%,进一步验证了利用色差法评价打叶复烤成品片烟质量的稳定性是可行的。

Abstract: In order to evaluate the quality consistency of strips after threshing and redrying with chromatic aberration method, redried Yunyan 87 BBSF strips were sampled at the output end of redryer, and the L^*, a^*, b^* values of samples were determined by automatic colorimeter. The obtained data were analyzed with normality test, their Mean-Range charts were plotted, and the process capability index (Cp) was calculated. The results showed that L^*, a^*, b^* of redried Yunyan 87 BBSF strips were in the range of 1.33 ≥ C_p>1.00, which indicated that the redried strips featured good quality consistency. Meanwhile, the blending uniformity of Yunyan 87 BBSF reached 85.72%, which proved that it was feasible to evaluate the quality consistency of redried strips with chromatic aberration method.
