I worked on a cranberry farm one summer where they used a cranberry grader to sort remove the fruit from the vines and separate the good from the bad. It is basically a bunch of boards at a slight angle so that any damaged or very small cranberries would bounce out, away from the good cranberries. Next the fruit rolls down a large comb like board where it is sorted by size. It is generally sold at that point and Ocean Spray would sort it by color depending on the final product. It was amazing how well such a simple and easy to repair machine worked
