Boost OEE And Find Smaller Metal Contaminants

‘Product effect’ (a phenomenon where the type of product being inspected can itself hinder the inspection technology’s capability to identify a particular contaminant) has long been a problem for food manufacturers. In the case of metal detection, product effect can be caused by a number of factors such as high moisture or salt content, temperature variations, size and shape of the product, orientation through the detector and packaging material.

Natural products such as liquids, pastes and slurries often have a high degree of moisture content that can vary significantly from one product to another. Due to product effect, conventional metal detector technology struggles to cope with this variation, leading to either a risk of high false-reject rates (and decreased OEE) or an unacceptable reduction in online sensitivity.
