Magnetic filter meets the highest food safety standard
The EHEDG (European Hygienic Engineering and Design Group) magnetic filter recently introduced by Goudsmit Magnetics is specially designed for the food industry. The filter is constructed of Neodymium magnets that provide more effective separation of very small ferrous particles as small as 15µm, weakly magnetic particles and even iron dust from sticky substances such as tomatoes and fruit juices. This hygienic filter is suitable for CIP systems: the magnet can be magnetically operated, without the need to open the filter housing for cleaning. The magnet has a maximum flux density of 11,300 gauss at the bar and removes the specified particles from both liquid and powdered products. The entire system is made of grade 316 stainless steel, is smoothly finished (Ra≤0.4?m) and is EHEDG certified.
Cleaning of the magnet occurs automatically. When production is stopped the magnet can be 'blown' out of the product flow so the captured ferritic particles fall off the magnet. Cleaning can take place during the CIP process. A separate CIP cleaning cycle flushes both the captured metal particles as well as the rinse. This prevents the captured particles from entering the product again elsewhere in the process. After this extra cleaning the complete CIP process can take place. The housing is constructed so that no product remains behind after cleaning (see animation on YouTube). The magnetic filter is used in tubes and/or pipelines in the food industry, where it performs deferrization of products conveyed under pressure. This way even the smallest iron particles can be filtered out of sticky substances (chocolate, pastes, powders or fruit juices), while these particles are normally carried off again by the raw material flow. Installation of a metal detector does not solve the ferro problem, because it is not able to detect the smaller metal particles. The hygienic magnetic filter is available in five standard dimensions (Ø 50 - 125 mm).
Goudsmit is 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.
