Fortress tunes into dairy metal inspection frequencies
With metallic inclusions from wire cutters to mixing tools remaining the number one contaminant in dairy processing and packing plants, Toronto-based Fortress Technology, one of the largest global suppliers of industrial food metal detectors, evaluates the three key frequency options and how to select the correct one for your dairy application.
The most widely used type of metal detector in the food industry functions on the principle known as the “balanced coil.” With a general-purpose search head, these can detect ferrous and non-ferrous metals, as well as stainless steels in fresh and frozen dairy products, whether unwrapped, wrapped, or in metallized films. Yet, unlike metal detectors designed for specific applications, these general-purpose search heads are still unable to detect every particle of metal passing through them. For optimal performance and sensitivity, the search head should be sized appropriately to the product being inspected.
