The moisture is one of active ingredients in the cigarette smoke and can be adjusted through manual control, and the inherent sensory quality of the cigarette is directly influenced by the moisture. Research has shown that the moisture in the cut tobacco can be effectively adjusted by controlling the process conditions. However, the generation mechanism and adjustment measures of the flue gas moisture are not deeply researched, which may be related to more influence factors of the flue gas moisture measurement. In view of the importance of moisture, in recent years, the accuracy requirement for moisture testing in cigarette smoke is becoming more and more strict. Meanwhile, the calculation of the tar level of the cigarettes relates to the moisture content in the total particulate matter, and the accurate numerical value of the tar amount in the total particulate matter can be obtained only after the moisture content and the nicotine content in the total particulate matter are accurately measured.
The heating cigarette is a novel tobacco product which heats a core substrate (below 300 ℃ or even lower) by utilizing a special heat source and only heats the core substrate without burning. The physical and chemical properties of the tobacco material (core base material) used by the heating cigarette are obviously different from those of tobacco leaves and traditional reconstituted tobacco leaves, particularly, the alcohol smoke agent with a high proportion is used, and the smoke agent has high hygroscopicity, so that the moisture content in the mainstream smoke of the heating cigarette is obviously higher than that of the traditional cigarette. When the cigarette which is not heated and burnt is smoked, condensate is found on the front cover and the rear cover of the catcher, and the traditional main stream smoke particle phase matter catching and extracting treatment mode is not suitable for catching and extracting treatment of smoke with high moisture content such as heated cigarette, thereby influencing the measurement result.
