ABSTRACT:
A tomato sorter is described for removing culls, e.g. green tomatoes from the good, red tomatoes. An image of each tomato passing the station is formed on a light diffusing plate. Diffused light from the plate is divided into first and second light beams from which all but the red and the green light components, respectively, are removed with filters. The remaining light is sensed by separate photo-multipliers, the output of which is used to form red and green light intensity signals. When the differential between the red and green signals exceeds a predetermined value, a reject signal is generated which actuates a mechanism for removing the affected tomato from the tomato flow.
