The invention discloses a tobacco leaf moisture content prediction model construction method based on a microwave penetration method, which comprises the following steps: measuring a plurality of tobacco samples with different moisture contents through a microwave moisture meter, and according to the trend change of a microwave voltage value and absolute ethyl alcohol with different volumes on a measurement result and a reference moisture content obtained by a drying method, obtaining a tobacco moisture content prediction model through a fitting mode. The microwave transmission method is only used for detecting the moisture content of a detected object and is irrelevant to the color and the shape of the detected object, and the detected object is immersed in absolute ethyl alcohol, so that the problem of measurement errors caused by the moisture in the air and the state of a sample is avoided, and the moisture content can be indirectly measured by combining the prediction model with the microwave transmission method. Therefore, the measurement efficiency, convenience and accuracy can be remarkably improved. On the basis of the method, the moisture content of the tobacco can be rapidly measured in a non-contact and more convenient mode, and the method has positive significance and important application value for the cigarette production process.
Description
technical field [0001] The invention relates to the technical field of tobacco index detection, in particular to a method for constructing a prediction model of moisture content of tobacco leaves based on a microwave penetration method. Background technique [0002] In the production process of the cigarette industry, the moisture content of tobacco is an extremely important indicator, which has a profound impact on the taste and final quality of finished cigarettes. Therefore, in the production process, the moisture content of tobacco at each process node is measured Detection is very necessary. In the actual production process, cigarette manufacturers usually measure the moisture content of tobacco according to the national standard "2 hours at 100°C drying method" (that is, drying in an oven at a temperature of 100°C for 2 hours) and infrared moisture meters. [0003] The national standard "2-hour 100°C drying method" mainly uses an oven to dry tobacco samples, and then ...
