Abstract
A shrimp processing system conveys raw peeled shrimps to an imaging chamber in which shrimp bits and shrimps with residual shell are detected and diverted from the stream of acceptable shrimps allowed to pass on to downstream processing. An ultraviolet (UV) light source in the imaging chamber is constantly on. A visual inspection system takes images of the passing stream of shrimp when a white-light source is turned on to illuminate an exposure region to detect bits, clumps of shrimps, and acceptable individual shrimps. The visual inspection system takes images of the passing stream when the white-light source is turned off and the exposure region is subjected only to ultraviolet radiation. The visual inspection system detects shrimps with residual shell in the UV images. Shrimp bits and shrimps with residual shell are diverted from the stream of shrimps by air jet nozzles to corresponding reject destinations.
