At Anuga Foodtec in Cologne (Hall 5.1/K/0.39), the Dutch Company Goudsmit Magnetic Systems has presented the All-Metal-Catcher –a combination of a magnet with a metal detector in a single system. This system makes it possible to remove both ferrous and non-ferrous particles from flows of materials in the foodstuffs industry. This system removes ferrous particles from 25 microns and non-ferrous particles from 0.6mm from powered (bulk) goods like for example coffee, cocoa, tea, powdered milk or sugar. The magnet has a strong magnetic force of 12,000 Gauss and checks raw materials for iron upon the commencement of production, or the end product just before it leaves the production hall. Thanks to its low overall height, it is possible to incorporate the magnet in an existing production process. This magnetic pre-sorting means that considerably less product is lost than with detection alone. 70% of metal pollution is often caused by iron and can be removed by magnets. The metal detector fitted after the magnet ejects other metals without a great deal of loss of product. The detectors are not susceptible to external influences (such as: moving metal parts, vibration, frequency controls, etc., and are self-monitoring.
