Special X-ray Technology Safeguards Fish Bone Detection
Consumers all over the world demand high quality fish without fishbones disturbing the eating experience. With specialised X-ray image technology from the Danish company InnospeXion, bones can automatically be detected at fish factories and thus ensure high quality fish, meeting the consumer demands.
Fish factories around the world face various challenges, notably concerning hygiene, robustness, cleaning and detection performance of bones. Customer complaints regarding unexpected bones in fish products and unmet food safety & quality standards are the most common causes for big recalls and returned shipments. This ultimately results in a massive food waste. This was exactly the challenge a Polish fish factory processing frozen fish blocks, frozen fillets, specials cuts, and breaded and deluxe puff pastry fish products faced. The Danish company InnospeXion is working hard together with food producers to implement quality control systems early in the production process, so that such wastes can be reduced and avoided as much as possible.
Unique x-ray technology
With novel technology from InnospeXion, the fish producer in Poland can now ensure high quality filets without bones thanks to a unique X-ray image technology. The InnospeXion fish bone detection system is based on the newest and most effective X-ray technology which automatically detects bones in trimmed fillets (Cod, Haddock, Red fish, etc.), pin bones in e.g. salmon and small bones in bits and pieces used for fish blocks. When a bone is detected, a signal is sent from a computer control system to a reject arrangement and bones can be transferred to a monitor in front of an operator who may withdraw the bone at the specified location.
The InnospeXion technology enables detection of fish bones down to 0.1 mm at up to 300 frames per second
Meeting demands of the quality-conscious customers
A study conducted in Norway documented the size of bones that the consumer is likely to detect upon eating a fish product. The study showed that generally, bones of a thickness lower than 0.3 mm are not likely to be detected by the consumer. The InnospeXion technology enables detection of fish bones down to 0.1 mm at up to 300 frames per second and operates 24/7.
Fully automatic system
At the fish processing factory in Poland, InnospeXion’s X-ray technology has provided a significant improvement, compared to traditional human inspection. They have achieved an automatic, robust, reliable and hygienically designed system that can safeguard bone free fish products, hence enabling a higher price per kilo and a highly reduced risk of having a shipment returned due to a too high bone content and thus preventing food loss. The novel technology therefore has a very short time of the return on investment.
