    Abstract: A modular star system for grading, cleaning, and transporting produce includes opposing, first and second hub modules with opposing, tapered surfaces, and plural finger modules separated by the first and second hub modules. Each finger module has finger members that are color-coded and the finger module and first and second hub modules are disposed on a rotatable shaft. Outer surfaces of either of the finger or hub modules are color-coded, and are substantially perpendicular to the long axis of the shaft. There is also a method of using the modular star system for grading, cleaning, and transporting produce.
