基于干燥脱水量的叶丝滚筒干燥加工强度品质校正技术

Quality correction technique for drying intensity of cut tobacco strips based on dehydrating levels

  • 摘要: 为解决制丝干燥段生产过程中干燥脱水量受来料条件和车间环境温湿度等因素影响,导致同牌号在制品批间变化较大,加工强度可控性差的问题,采用均匀试验设计方法,针对干燥脱水量的不可接受区间,建立了干燥段加工工艺参数对香韵、舒适性、烟气特征影响的二次多项式逐步回归模型,并根据均匀设计试验结果,开发了“加工强度品质校正技术”,该技术可为脱水量偏离的批次提供适宜的参数匹配。将品质校正技术在中控MES系统中进行集成,研发了加工强度品质校正系统,该系统应用后香韵特征(加工强度)符合度较应用前提升12.8百分点,批间感官评价得分波动降低53.3%。

     

    Abstract: Fluctuation in moisture contents of dried cut strips of different batches are caused by uncontrollable factors such as ambient temperature and humidity, climate and production time. To control the processing intensity precisely, a designed experimental method was used to establish quadratic polynomial stepwise regression models to describe the drying section on leaf aroma note, comfortableness and tobacco smoke characteristics. The aim was to reduce the unacceptable intervals of drying dehydrating amount. On the basis of the experimental results, a "quality correction technique for processing intensity" was developed to provide appropriate parameters matching for the batches with deviated dehydration amount. This technique was integrated into a MES central control system to develop a quality correction system for processing intensity, the compliance rate of aroma note characteristics (processing intensity) increased by 12.8 percentage points and the sensory quality fluctuations between batches decreased by 53.3%.
