Custom Sanitary Slurry Electromagnetic Separators for Palm Oil Refinery in Malaysia Solve Blackening Caused by Trace Iro

2026-07-21

a large palm oil refining group in Johor, Malaysia carried out renovation on wet refining procedures of palm oil. Tiny iron wear particles are mixed in the oil during palm fruit pressing and decolorization. Iron ions catalyze oil oxidation under high temperature, darkening finished palm oil and blocking export access to EU food markets. Simple magnetic bars used previously cannot reach sufficient iron removal precision, and manual cleaning easily causes secondary oil contamination.

Full production lines adopt food-grade 316L stainless steel high-gradient slurry electromagnetic separators, matched with front-end rotary permanent magnet grates for pre-removal of coarse iron. The equipment is equipped with built-in automatic CIP backwashing structure to clean magnetic cores without production shutdown. The stable magnetic field strength of 12000GS captures suspended iron particles as small as 0.5μm. The whole machine passes EU FSMA food contact certification, resists weak acid corrosion of palm oil, and adapts to high-temperature and high-humidity tropical workshop environments.

After technical transformation, iron content in finished oil drops below 8ppb, and oil oxidation stability rises by 65%, pushing EU export orders up 41% month-on-month. Automatic iron cleaning cuts manual labor hours by 80%. Three surrounding palm oil processing factories in Malaysia visited the site to inspect the same sanitary magnetic separation solution.
