| Summary, etc. | An acoustical sorting system was developed to detect hollow heart of potato tubers (Spunta variety). The system includes a microphone, digital signal processing hardware and material handling equipment. It was found that upon impact with a steel plate, potato tubers with no hollow heart emit sound with higher signal magnitudes than with hollow one. Linear discriminate analysis was used to classify potato tubers using three features extracted from the microphone signal. One of the discriminate features is the integrated absolute value of microphone output signal. The other two features are the number of data points in the digitized microphone signal after impact that have a slope and signal magnitude below preset threshold levels. The classification accuracy of this system is approximately 98%. The internal quality of potato tubers can be detected by acoustic impact method. The resonant frequency of potato tubers after dropping was found from acquired signal. The hollow heart existence of potato tubers can be evaluated by the resonant frequency of vibration signal of dropping tubers. This technology of acoustics to evaluate the hollow heart existence is more reliable and accurate especially for export. |
