A sorter ejects defective products from a stream of product delivered to a sorting zone. A camera (6) has a line of sight (5) to the sorting zone and provides an image of the stream at the safety zone. A blast bar (3) generates one or more air jets directed at the safety zone. A processor (9) processes the image to detect defective products and causes the blast bar to eject defective products from the safety zone. The zone of impingement of the air jet(s) on the stream is downstream of the line of sight and the blast bar is upstream of the line of sight. |
