摘要

PURPOSE:To securely detect the initial rotting of the peel of the tangerine by irradiating the tangerine with ultraviolet wavelength light and causing light emission at a rotting part. CONSTITUTION:The machine frame 12 of the detecting device 10 is fixed on the floor surface of a conveyance line and when tangerines 16 are thrown in form a feed slot 14 provided to the right surface of the machine frame 12 continuously, the tangerines 16 are conveyed axially while twisted and spun by a couple of rolls 18 and 20. Then the moving tangerines 16 are irradiated with the ultraviolet wavelength light of a high-voltage mercury vapor lamp 32 from above and a vidicon 34 mounting a filter 36 photographs the tangerines 16 continuously and inputs its video signal to a video processor 38. Here, if a tangerine rots in the initial stage, oil cells characteristic to the tangerine are broken in the peel and united with the peel layer to form jelly structure, wherein various coloring components from the oil cells are dispersed. Then those coloring components absorb the ultraviolet light and emit visible light and the processor 38 processes the video signal into a binary signal to detect and measure the light emission area from the initial rotting part.
