The invention concerns a method and a device for detecting irregularities in a product, in which at least one light band ( ) is directed towards this product ( ), which moves in a particular direction through a detection zone, so that said light band ( ) is scattered and/or reflected by said product, and the scattered light is detected by at least one detector ( ) in order to detect irregularities in the product and the light stream scattered by a part of the product and captured by said detector ( ) is adjusted so that it is independent of the position of said part in said detection zone.

Method and apparatus for detecting irregularities in a product

The invention concerns a sorting apparatus for granular products (,), such as peas, nuts, raisins, and suchlike, with a detection system (,), a removal system (,) and a transport device (,), where the latter has a sloping distribution surface (,&prime;) over which said products (,) are moved, whereby said surface (,&prime;) is convex over at least a certain distance in the direction of travel (,) of said products (,), such that said surface (,&prime;) has a curvature in the direction of fall of said products (,) equal to or slightly less than that of the path (,) which the products would follow at said surface (,&prime;) in free fall, independent of said surface (,&prime;).
