Foreign body detection in food processing

Context

Quality control: search for inputs in a production of kibbles for animal feed, spread out in bulk on a conveyor belt and running continuously.

Targets

Detection of plastic debris of different sizes and colours.
To signal the intruders to the operators.

Solutions implemented

Development of a customised application and installation of a complete vision system with a hyperspectral camera.

Control points

Search, detection, localisation and reporting of any element with a spectral fingerprint different from that of the croquette.

Special points

Possible classification of different types of inputs. The control could be "duplicated" for metallic inputs for example.

Customer benefit

Increased production safety for a better satisfaction of the final consumer.
Optimisation of the production tool by reporting events that may indicate mechanical malfunctions upstream.
