Background

The method for detecting the moisture in the tobacco leaves generally comprises a direct method and an indirect method, wherein the direct method generally adopts a constant-temperature drying method under normal pressure in the classification of the threshing and redrying tobacco leaves, and the principle of the method is that a sample is dried at the temperature of 100-plus 105 ℃ by utilizing the property that the moisture boils and evaporates at the temperature of 100 ℃, so that the moisture in the tobacco leaves is evaporated, more or less volatile substances in the tobacco leaves are evaporated, and a part of easily-pyrolyzed substances are lost, so that the detection result is higher. In order to avoid the error and reduce the loss of volatile substances, the tobacco industry specifies that 5-10g of tobacco leaves are sampled and dried in an oven at 100-105 ℃ for 2h to measure the moisture.

Therefore, in the tobacco leaf grading process, the moisture content is judged only by means of manual touch, grading personnel flow frequently, and the moisture judgment accuracy is very low, so that the tobacco leaves with large moisture content enter the qualified graded tobacco leaves, a large amount of rotten tobacco leaves are generated in the subsequent storage process, and the loss of the tobacco leaf value is caused.

Secondly, although the moisture of the tobacco leaves detected by an indirect measuring method of an infrared moisture meter can be monitored and judged in real time, the method cannot be applied to the tobacco leaf grading process due to the limitations of the field environment and the manual grading mode.
