Abstract
The present invention is related to an apparatus for sorting products, in particular granular products such as raisins, blueberries but also pellets e.g. plastic pellets. The sorting apparatus comprises a supply system, a detecting system, a selecting system and a chute. The chute comprises a first guiding element having an upwardly-curved surface for guiding the stream of product moving under influence of gravity towards the detecting system and the selecting system. Optionally the chute comprises a second guiding element having a surface which is downward-curved at least over a certain distance along the movement of the stream of products, such that products which are propelled by the first guiding element and received by the second guiding element are redirected in an essentially vertical downward direction. The detection system will inspect the products when moving in a substantially vertical direction.
