What Are The Metal Detector Test Standards?

Metal detection systems test pieces are a crucial part of any food industry production line.  These small pieces can help to ensure that your metal detection system is functioning properly and your products are reaching customers safely.  The specific type of piece you use will depend on a number of factors including the kind of detector system you have and the size and makeup of your product.

There are three basic types of detector system: gravity fed, conveyer fed and pipeline.  Each one has its own specific method of operation and, consequently, requires its own unique approach to testing.  In general, testing involves sending test pieces of ferrous, non-ferrous and stainless steel composition through the production line to ensure that the detector responds properly and automatically rejects potential contaminants.

Conveyer fed systems move packaged products through the detector by means of a conveyor belt.  Because these systems can handle products already in their final packaging, they can be more easily tested using sample packs.  Metal detection systems test pieces in these instances can be shaped as cards, rods or sticks and can be incorporated comfortably within the test sample.

Gravity fed systems use a series of pipes and chutes stacked vertically, enabling the natural flow of gravity to move the product.  These systems are used most commonly for dry, free flowing products such as grains, flours, cereals, rice, nuts, sugar and plastic pellets as well as vertical packaging of liquids, pastes and slurries.  For these systems, smaller test pieces can be incorporated directly within the product stream provided they are able to pass smoothly through the detector aperture.

In pipeline systems, a section of non-metallic pipe is used to pass liquid, slurry or paste products through the detector.  These systems are used for sauces, dairy products, juices, sausage and other meat products. In this case, the metal detection systems test pieces used would have to be quite small in order fit through the piping or slim test pipes can be used between the pipe and the detector head itself.

Whichever type of detector you use, having strict testing procedures in place is extremely important.  Tests should be conducted at regular intervals, usually hourly but at the very least at shift changes and between different products.  The more often your detectors are tested, the more easily you can identify and correct problems and avoid potential contamination.
