Detection device and detection method for quality of white kidney beans

The invention discloses a detection device and a detection method for the quality of white kidney beans. According to the detection method, the qualified white kidney beans are divided into m white kidney bean samples with the same mass; a sensor array is used for detecting each sample in sequence to obtain m signal to noise ratio peak values; a computer is used for calculating an average value of the signal to noise ratio peak values and defining the average value of the signal to noise ratio peak values into a threshold value Thr; a white kidney bean sample W to be detected is detected to obtain a signal to noise ratio peak value sigma of the white kidney bean sample W; a non-linear self-calibration dynamic cataloging model is used for calculating a dynamic cataloging parameter delta of the white kidney bean sample W; the computer is used for judging whether the white kidney beans is qualified or not. The detection device and the detection method disclosed by the invention have the characteristics of accura
