温湿度调控下贵州烟叶吸湿力学性能的多尺度耦合机制与分型加工
Multi-scale coupling mechanism and typed processing of moisture absorption and mechanical properties of Guizhou tobacco leaves under temperature and humidity control
摘要
Abstract
To address the issues of processing quality fluctuations and raw material loss caused by inconsistent moisture absorption behavior of tobacco leaves during the threshing and redrying process,this study systematically analyzed the moisture absorption characteristics and mechanical property changes of major tobacco varieties produced in Guizhou un-der the environment of 25 ℃ and 11％～75％relative humidity(RH).The results revealed that the moisture absorption process of tobacco leaves exhibits a three-stage characteristic,with penetration force showing an extremely significant positive correlation with moisture absorption rate.Additionally,a moisture absorption threshold phenomenon of adhesion force was identified at approximately 1.5 N.Based on the correlation mechanism between moisture absorption and me-chanical properties,tobacco leaves were classified into three processing attribute types through cluster analysis,and a Fisher discriminant model was established with a classification accuracy of 91.2％.Differential leaf conditioning and re-drying process parameters were proposed according to the classification results.Industrial verification indicated that this strategy can improve processing uniformity by 22.4％and reduce the breakage rate by 1.8％.The research findings pro-vide a theoretical basis for the parameter setting and intelligent control of tobacco processing equipment,and hold signifi-cant application value for achieving quality improvement and loss reduction in redrying production.关键词
