Metal detection systems are designed to identify foreign ferrous, non-ferrous and stainless-steel contaminants in food products and reject those products before harming consumers. These systems are sometimes challenged by what is known as “product effect,” which is produced by certain product properties (e.g., high salt, moisture or iron content and temperature variation) that can produce signals causing the metal detector to falsely reject uncontaminated products.
A new technology dramatically reduces product effect and minimizes false rejects, thus reducing the risk that clean product will be rejected and wasted, and preventing contaminated products from reaching the market.
