Magnet filters weak magnetic particles from foodstuffs

Magnet filters weak magnetic particles from foodstuffsGoudsmit Magnetic Systems BV will introduce a new type of magnet at the Solids 2013 Fair in Rotterdam. This semi-automatic clean-flow magnet is composed of magnetic bars, and it filters weak magnetism and very small metal particles (from 30 mHu) from – among other things – foodstuffs.

Particles smaller than 1mm are not detected by a metal detector and continue to be present in the product. The system reaches a maximum magnetic value of 11,500 gauss, while the minimum value is never below 700 gauss – meaning that stainless steel 316 particles can also be removed. The magnet can be used in free fall pipes in various industries and needs a low built-in height of 150mm.

Following the development of this system, Goudsmit, together with its clients, has developed a standard test for measuring the efficiency of the magnets in products contaminated with metal. This makes it possible to compare the various magnet solutions and make the appropriate selection.

The self-cleaning clean-flow magnet is composed of two powerful Neoflux magnetic bars, mounted one above the other. This means that the product always comes into contact with the magnet. The magnetic bars are composed of Neoflux (Neodymium-Ferro-Boron) magnets, which enables a magnetic value of 11,500 gauss to be reached.

After the production process is switched off, the cleansing cycle can be started.

During the cleansing process, the magnetic bars are manually removed from the product flow and then cleaned pneumatically, whilst the iron particles are released and disappear into the waste channel. After cleansing, the magnetic cores are put back into place and production can be resumed.

– Goudsmit Magnetic Systems BV will be located at Stand A1017 at the Solids 2013 Fair in Rotterdam
