At the Powtech in Nuremberg, you can visit Goudsmit where you can see an updated EHEDG magnet filter that has been specially developed for the food industry. The filter is composed of Neoflux® (Nd-Fe-B or rare-earth) magnets that provide for an efficient separation of minute iron particles from 5 ų , weak magnetic particles and even iron dust. It generates a magnetic field of a maximum of 10,700 Gauss (+/-5%) on the bars and removes the particles from liquid products and powdered products. The entire system is made of stainless steel 316, smoothly finished (Ra≤0.8ų), and complies with the HACCP/EHEDG norm; the highest standard in the field of food safety.
Recently, Goudsmit has become the first magnet supplier to be admitted to the European Hygienic Engineering & Design Group. The EHEDG is a consortium of installation suppliers, companies in the food industry, research laboratories and national public health bodies that aim at the highest standards of food safety. EHEDG sets standards for avoiding contamination or the growth of damaging micro-organisms, cleaning and decontamination capacity, and the use of materials and surface finish. It tests the product designs in the field of cleaning, sterilization and bacteriological impermeability. Only those firms that comply with the standards set are eligible for the EHEDG certificate.
The removal of the captured metal particles done in 3 ways: manually, whereby the operator can easily pull apart the magnetic bars covered by an extractor; manually + pneumatically, whereby the cleaning is done automatically and, according to the most recent method, pneumatically + CIP (Cleaning In Place), whereby in addition to cleaning also the rinsing of the magnetic bars is done automatically. The housing is constructed in such a way that after cleaning no products remain. The magnet filter can be used in tubes or piping in the food sector and serves to remove iron particles from products that are transported under pressure. Even the most minute iron particles can be filtered in this way from sticky products (chocolate, pastes, powders or fruit juice). Usually, these particles remain in the raw materials flow. The placement of a metal detector does not resolve the issue of iron because it cannot identify the smaller metal particles. The magnet filter is available in 7 standard dimensions ( Ø 50 - 200 mm) and has a flange connection according to DIN 11864.
