Abstract

The invention discloses a device and a method for detecting water content of fresh tobacco leaves. The device comprises a detection box, a first electrode plate, a second electrode plate, a frequency measuring device and a computer, wherein the detection box is internally provided with an SAW (Surface Acoustic Wave) harmonic vibration detector and a stabilized voltage supply; the stabilized voltage supply is electrically connected with a power supply end of the SAW harmonic vibration detector; two detection ends of the SAW harmonic vibration detector are electrically connected with the first electrode plate and the second electrode plate respectively; the output end of the SAW harmonic vibration detector is electrically connected with the input end of the frequency measuring device; the output end of the frequency measuring device is electrically connected with the computer. With the method, the fresh tobacco leaves to be detected are detected through the SAW harmonic vibration detector, a characteristic value M is obtained after nonlinear stochastic resonance processing of frequency of output signal of the SAW harmonic vibration detector, and the characteristic value is substituted into a forecast formula of proportion of the water content to calculate and obtain the water content of the fresh tobacco leaves. According to the device and the method, the water content of the fresh tobacco leaves can be quickly and accurately detected in a lossless manner.

Description

technical field [0001] The invention relates to the technical field of water content detection, in particular to a fresh tobacco leaf water content detection device and method. Background technique [0002] In the study of flue-cured tobacco technology, the moisture content of fresh tobacco leaves is closely related to the curing properties of flue-cured tobacco, and the moisture content of fresh tobacco leaves is directly related to the optimization of the curing mode and the important basis for the rationalization of the curing process. The dry matter content of fresh tobacco leaves with high water content is low, and the decomposition and transformation of dry matter, yellowing and browning are all faster. Tobacco leaves with less water content have higher dry matter content and longer yellowing and browning time, which is also an important factor related to the quality of cigarette products. [0003] The standard method of moisture content measurement is the drying meth...
