Abstract:
An industrial experiment was carried out to investigate the influence of inspection time and blemished fruit rate on inspection performance of orange fruit. Forecasting equations specified from an existing theory were developed. The equation parameters were estimated, based on 188 sorting tests, for two different classes of slight and serious fruit defects. It was found that the inspection time required for the 'slight defects' class was much greater than that for the 'serious defect' class. This result should be taken into consideration, especially when the ratio between the defect classes differs greatly from the usual, such as in forecasting human labor required to complete inspection performed by a harvesting crew or vision equipment. The findings indicate that the blemished fruit rate does not affect inspection performance.
