Metal detectors are ubiquitous in food processing facilities. They are most commonly used at the end of the line and as the last line of defense to support food quality and safety before a packaged product is on its way to the consumer. The core technology has always had its limitations and compromises such as noise that can interfere with signals and product effect that can confuse a wet product with metal.
While metal detection technology has slowly evolved over the years, the challenges facing food processing have changed considerably. There are increasingly demands such as new regulations, retailer detection mandates and greater productivity demands. The stakes are higher too: the potential for a costly recall and collateral damage via social media.
