Goudsmit Magnetics introduces a new generation of magnetic separators that are used to remove metal particles (>30 µm) from foodstuffs like coffee, cocoa, malt, rice, sugar, and flour, but also from other powder and bulk materials.

The Easy Clean flow drawer magnet features user-friendly cleaning, improved flow, and the high Gauss values of the bars. In contrast to previous designs in which such magnets were fitted with two layers of thin (Ø25 mm) bars, the new design contains a single row of Ø50-mm-thick bars. New measurement techniques, including simulations of magnetic fields and tests in the company's test center, have shown that this results in a higher separation yield. This is because the thicker bars remain in contact with the magnetic particles longer. An additional benefit is the reduced height of the magnet as a whole, which means it requires less installation height. A single row of bars results in improved product flow, which is particularly beneficial when it comes to poorly flowing powders.

Cleaning
The pneumatic magnetic bars simplify the cleaning process. The bars are slid out along a guide and, once outside the housing, the magnets are exposed by blowing them out of the bars. A plate then retains the captured metal particles, after which they fall into a collection tray.

With its enormous magnetic holding power of 12,000 Gauss at the rods, the Easy Clean flow magnet is also suited for the separation of small stainless steel particles. The tests and measurements mentioned above also showed that magnetic holding power alone is not enough to separate stainless steel particles. It is also of critical importance that these particles come into contact with the bars as they flow past. To accomplish this, the company can fit deflectors in the magnet, providing good control over the direction of product flows containing weak magnetic (stainless steel) particles. This ensures that the product always contacts the bars.
