Abstract
A sorting machine has a member a part of which has a translucent viewing area. Material to be sorted is passed adjacent to but spaced from a surface on the translucent viewing area. Light passing through the translucent viewing area is viewed and in dependence on such viewing, an ejector separates. desired and undesired material. A film of washing liquid is directed over the surface of the translucent viewing area, the film then passing to a liquid removal zone which is located on another surface of the member. The liquid removal zone is disposed in a position in which the ejector does not cause the material to be wetted by the liquid.
