Device and method for separating non-tobacco related materials from a mass flow of small parts and use of the device

A device for separating non-tobacco related materials from a mass flow of small parts, comprising:

• a feed device, arranged to guide a mass flow in a transport area, configured to convey the mass flow in a transport direction;
• a detection device configured to detect a non-tobacco related material in the mass flow and to generate and transmit a non-tobacco related material detection signal;
• a rejection device configured to receive the non-tobacco related material detection signal and to remove the non-tobacco related material from the mass flow by deflecting the non-tobacco related material in a rejection direction;
• a discharge device configured to receive the mass flow from which the non-tobacco related material has been removed;
• and
• a non-tobacco related material receiving device which is configured and arranged to receive the removed non-tobacco related material,
• the non-tobacco related material receiving device comprising a retaining device in a form of a chute with chute walls delimiting a retaining volume, and at least one deflecting member,
• wherein the at least one deflecting member is configured to be inclined by an angle lying in a rejection plane, in which the transport direction and the rejection direction lie, and to extend from a fastening position on one of the chute walls with a free end that extends into the retaining volume and is arranged downstream of the fastening position in the rejection direction.
