Top 5 Considerations When Upgrading From Metal Detection To X-Ray Inspection

By Erik Brainard, Anritsu Infivis

Surprise objects in food — and the disgust, anger, and fear they create — can evolve into viral news faster than you can say “recall!” If the foreign object happens to be broken glass, a hypodermic needle, bone, or stone, the item could have been caught during processing by an X-ray detection system.

The good news is food processors are increasingly upgrading from metal detection to X-ray systems to strengthen their foreign object detection programs. Metal detectors, historically the most common detection method, can only uncover metals. X-ray detection works by revealing differences in density. Therefore, X-rays can find a broad array of inorganic objects, including metal, quite effectively.
