摘　　要：为解决生产过程中在线红外水分仪检测探头蒙尘及结露现象,使用固定范围内的清洁压空不间断地对其进行吹扫清洁,可有效提高在线红外水分仪对不同水分下烟丝检测的准确性和稳定性,利于物料水分的在线检测与控制。运用单因素多水平试验的方法,选择卷烟制丝生产线上3种不同物料状态和水分的样品,比较清洁压空使用量对其各自在线红外水分仪检测结果影响程度,进一步确定出对提高水分仪检测准确性最适宜的清洁压空使用量。通过对梯度测试结果进行比较分析,得出适宜的清洁压空使用量为0.033~0.066 MPa。In order to solve the phenomenon of dust and condensation on the detection probe of the online infrared moisture meter in the production process,the cleaning pressure within a fixed range was used in the production pro⁃cess to continuously purge and clean it,which could effectively improve the on-line infrared moisture meter to cut to⁃bacco under different moisture levels.The accuracy and stability of the detection were conducive to the online detec⁃tion and control of material moisture.In this paper,using the method of single factor and multi-level test,three kinds of samples with different material states and moisture content in the cigarette making production line were selected to compare the influence of the usage of clean air on the detection results of their respective on-line infrared moisture meter,and further determine the most appropriate usage of clean air for improving the detection accuracy of moisture meter.Comparing and analyzing the results of the gradient test,it was concluded that the appropriate amount of clean air pressure was 0.033~0.066 MPa.
