Metallic inclusions are the number one contaminant in food products, causing product quality and consumer safety issues. Phil Brown, sales director, Fortress Technology, looks at the technologies behind effective metal detection, explains the three key frequency options and why it is essential to select the correct frequency for your food application Many factors will determine the theoretical sensitivity of a metal detector used in the food industry. Among them the aperture size (the smaller the aperture, the smaller the piece of metal that can be detected), the type of metal, product effect, and the type and orientation of the contaminant as it passes through the detector. Environmental conditions, such as airborne electrical interference, vibration and temperature fluctuation may also affect performance.
