X-ray system detects tiny contaminants

An X-ray inspection system introduced into Europe this month, can detect foreign bodies in packed and unpacked fresh foods.

Ishida Europe said its advanced X-ray inspection system is already a proven top seller in Japan.The company has now launched the IX-GA range into Europe for the first time. Keeping contaminantsout of products is essential for food processors, as recalls can lead to huge costs and fines, alongwith loss of consumer trust in the brand.

X-ray dectection offers advancements over standard metal detectors as it is not only able to detect metal but also other foreign materials. In addition, it distinguishes between 'legitimate' metal, such as clips on the ends of sausages or aluminium tins, while still monitoring and identifying unwanted items.

The IX-GA range uses self learning algorithm technology to offer detection that is sensitiveenough to find impurities down to 0.3mm in size. It can also be used spot missing items or damaged products. In addition, the place of contamination can be accuratelypinpointed, Ishida stated.

The machine can handle top sealed and thermoformed trays and flexible bags as well as unpacked product. It features aWindows XP operating system. An auto-set function allows the X-ray output and sensitivity level to be automatically set up for each product.

The machine's conveyors and belts are manufactured to international standards. Ishida says it hasdesigned the machine with hygiene in mind. Tool-free access is available to all parts, allowing for fast cleaning.A stainless steel body and three sets of lead curtains provide protection for operators.

Other safety features include warning lamps when the machine is in operation and automatic stopping of the X-ray process if the inspection cover door is opened or if a product remains in the inspection area.

"Today with heightened awareness of food safety among consumers, manufacturers want maximum peace of mind, knowing that the products that leave their factories are totally safe,"stated Ishida Europe marketing director Paul Griffin.
