Liquimag rare earth magnets simplify metal removal

29 August 2012


S+S Group says the latest version of its Liquimag from S+S Inspection uses an array of rare earth neodymium magnets to attract and hold the smallest magnetic particles in liquid and paste food applications, including some stainless steel grades.

The company, which supplies metal detection and colour sorting equipment using the latest technology, says the new Liquimag produces a very high magnetic flux density of 13,700 gauss.

The use of such powerful and permanent magnets “eliminates the need for any form of power supply”, the company says, allowing the Liquimag to be installed in the most convenient and effective position on a pipeline.

The units are certified for ATEX Zone 0 operation, while the solid stainless steel construction is fully compliant with all IFS, HACCP and BRC requirements.

“The simplest method of removing metal that can be magnetised is to use an array of strong permanent magnets,” S+S Inspection says.

“However, as most food processing equipment is made of stainless steel, which is only slightly magnetic, an extremely strong magnetic field is needed to remove all metallic contamination.”

Maintenance for Liquimag is limited to periodic removal of the collected contaminants from the magnetic rods – a task made quick and simple by the company’s Easy Clean design.

As the neodymium rod magnets are contained in stainless steel tubes on which contaminants are collected, when cleaning is needed the complete magnet assembly is simply removed from the body of the unit and the magnets withdrawn, allowing all the collected contamination to be easily removed.
