Influence and application research of ambient temperature and humidity in primary processing on tobacco moisture content between key processes

为揭示环境温湿度对制丝过程加工质量的影响规律,系统开展了制丝环境温湿度对关键工序间烟草含水率的影响及应用研究。结果表明,制丝室内环境温度明显高于室外环境温度,且两者具有较强的正相关性;越靠近室外,室内环境温湿度对室外环境温湿度影响越明显。在该制丝车间条件下,制丝环境湿度对松散回潮与加料工序间烟草含水率具有较强的负相关性,相关系数为-0.705 3;制丝环境温度对加料与叶丝干燥工序间烟草含水率具有较强的正相关性,相关系数为0.831 4;制丝环境温湿度对叶丝干燥与叶丝冷却工序间烟草含水率的影响基本可以忽略。基于制丝环境温湿度变化因素对制丝工艺技术标准进行合理优化设计,能有效提升制丝过程加工质量的稳定性,将对提升卷烟加工质量及产品质量稳定性具有重要的现实意义。

In order to reveal the influence of ambient temperature and humidity on the processing quality,the influence and application of ambient temperature and humidity in primary processing on tobacco moisture content between key processes were systematically studied.The results showed that the indoor ambient temperature of primary processing was significantly higher than the outdoor ambient temperature,and there was a strong positive correlation between them;the closer to the outside,the outdoor ambient temperature and humidity were more affected by the indoor ambient temperature and humidity.Under the conditions of the primary processing,the ambient humidity had a strong negative correlation with the tobacco moisture content between loosening and conditioning process and tobacco casing process,and the correlation coefficient was-0.7053;the ambient temperature had a strong positive correlation with the tobacco moisture content between tobacco casing process and drying process of cut tobacco,and the correlation coefficient was 0.8314;the influence of ambient temperature and humidity on the tobacco moisture content between drying process and cooling process of cut tobacco could be ignored.Based on the variation factors of ambient temperature and humidity of the primary processing,the reasonable optimization design of the technical standard of the primary processing could effectively improve the stability of processing quality,which would have important practical significance in improving the stability of cigarette processing quality and product quality.
