Most modern X-ray technology detects metal, glass, ceramic and stone themselves in aluminum packaging Balingen/Paris, September 30, 2010 – glass splinters in the carrot salad or metal particles in the strawberry yogurt: technical errors in the production process are often the trigger for a callback. Companies face in these cases not only with image damage, but in the case of personal injury with high claims. While much of this expensive and risky actions could be avoided by a better detection. On the SIAL 2010, international trade fair for food in Paris, presenting the system provider Bizerba from October 17-21 the new product-inspection system XRE with advanced X-ray technology (Salon IPA, Hall 7, stand F085) the principle of the system is simple: an X-ray tube with integrated high-voltage power supply is mounted under a conveyor belt. The rays take on the product and be absorbed by its individual components vary. Above the conveyor belt is a high resolution detection unit which converts the transmitted radiation into an electrical signal, which ultimately a digital X-ray image is created. This image is evaluated with the help of a product-specific visualization software.
The XRE can attain a throughput of up to 400 packages per minute. The XRE detected metal, glass, ceramic or stone – even in closed aluminium packaging so far it was hardly possible to detect metallic contaminants in cans or in closed aluminium packaging. With the Bizerba XRE product inspection system all foreign objects can be detected, which better or worse absorb the X-rays due to its density, chemical composition, or their mechanical dimensions than the surrounding product”, explains Dieter Conzelmann, Director industry solutions market at Bizerba. This applies equally to impurities from metal, glass, ceramic and stone. Some plastics”, says Conzelmann, PVC or rubber, as well as various product defects, such as The system can detect cracks and air pockets”.
