Abstract
A sorting apparatus for sorting material into desired and undesired pieces or portions includes a moving reflective surface such as a rotating cylindrical drum which is interposed between an illuminated background and a viewing system so that the background is indirectly viewed via the reflective surface. Any liquid or other debris from the product spills onto the reflective surface, rather than the background and is then moved away to be cleaned off. Thus, the viewed optical characteristics of the background remain constant and periodic cleaning of the background is not required.
