ABSTRACT:
A device for detection and removal of foreign bodies from vegetables dispersed and transported on a conveyor belt consisting of a multichannel detection system based on reflection analysis of polarized infra-red light. The reflected light is amplified, filtered and applied to a delayed automatic gain control circuit (A.G.C.). The A.G.C. output is compared with a reference voltage window to control the ejection system.
