ABSTRACT:
An automated color sorter for fruit and the like produces signals in the red and green spectrum from light reflected by each piece of produce passing an inspection station and operates upon these signals to generate color level signals employed to physically direct individual items according to predetermined color grades thereof. Computer operation upon the color level signals allows variation of sort levels or points and continuous inventorying of produce in predetermined grades.
