The moisture content in tobacco during processing not only directly affects the physical characteristics of the tobacco, such as elasticity, toughness, filling property, combustibility and the like, but also directly affects the appearance and the internal quality of the tobacco, such as color, aroma, taste and the like, and also affects the biochemical changes in the tobacco, such as the activities of various enzymes, the decomposition and the transformation of substances contained in the tobacco and the like. Therefore, in each link of cigarette production, the moisture content of tobacco must be strictly detected and controlled to ensure the processing quality of the tobacco.
The water content of the sample is detected by various common detection methods, such as an oven method, a Karl Fischer titration method, a gas chromatography method, an infrared method, a microwave method and the like. The Karl Fischer titration method is taken as a classical moisture quantitative method, can accurately determine the real moisture content of a sample, but has low efficiency of batch detection of a large amount of daily detection samples of cigarette industry enterprises; the gas chromatography is suitable for measuring the moisture content of batch samples (such as smoke moisture measurement), but the detection time, particularly the pretreatment time is long; the two methods of Karl Fischer titration and gas chromatography have high requirements on operators, instruments and equipment and detection reagents, and the detection cost is high.

The oven method has been widely adopted by the tobacco industry due to its simple operation and practicality. However, the tobacco moisture is measured by using the oven and needs to be dried for 2 hours at the temperature of 100 +/-2 ℃, the detection time is long, the efficiency is low, the quality of the sample before and after drying needs to be manually detected, the workload is large, and the detection result is greatly influenced by human factors.
