Magnetic Filters: What They Must Meet from a HACCP and Hygiene Perspective
In the food and pharmaceutical industries, it is not enough for a magnetic filter to simply work. It must meet strict requirements for hygiene, materials and documentation — otherwise a protective element becomes a source of risk.
Why standard industrial filters are insufficient
Standard magnetic filters are designed for performance, not for hygienic environments. They have threads, gaps and dead zones. In food or pharmaceutical production this is unacceptable.
What a hygienic magnetic filter must meet
Material in contact with the medium — stainless steel resistant to corrosion, cleaning agents and sterilisation. No parts made of carbon steel, zinc or plastic that could contaminate the product.
Hygienic design without dead zones — internal surfaces must be smooth, without sharp corners or hard-to-reach areas. A properly designed filter allows complete draining and cleaning without dismantling the entire system.
Resistance to CIP/SIP processes — filters in food and pharmaceutical lines undergo regular chemical or thermal sterilisation in place. The filter must withstand these cycles without degradation of the magnets or seals.
Documentable capture for HACCP — the HACCP system requires demonstrable control of critical points. The magnetic filter must allow recording of capture — the quantity, cleaning frequency and filter condition — to pass an audit.
