Mettler-Toledo Safeline Profile Advantage metal detector

Mettler-Toledo Safeline has launched the Profile Advantage metal detector which can reveal more metal contaminants than previous traditional systems when inspecting challenging applications such as wet, chilled or warm foods. As a result, it reduces the number of false rejects by up to 95%, allowing for cost savings in production environments including meat and poultry, dairy, bakery and ready meals.

Previously the ‘product effect’ (the electrical signal detected in some foods with a high moisture, salt content or packaged in metallised film) has reduced detection sensitivities significantly below the levels achieved with inspections of dry, non-conductive food products. Using a sophisticated inspection algorithm, the metal detector all but removes the product-effect phenomenon from the process. This results in up to 50% improvement in detection sensitivity levels irrespective of packaging material.

The detector uses multi-simultaneous frequency (MSF) technology. Unlike conventional metal detectors that simply capture and store the active product signal, the Profile Advantage modifies the signal during set-up so that the food product presents itself as if it were a dry product.

For manufacturers of products with stringent hygiene requirements, the detector has a robust, hygienic design. With a casing made from stainless steel, the system is capable of withstanding harsh washdown regimes, while curved edges and corners eliminate potential dirt traps, minimising the risk of biological contamination of the food. The metal detector is also available with optional bespoke conveyors, enabling manufacturers to customise the system to their particular production needs.
