AB MAURI protects soya milling process from metal contamination with nine magnetic separators from Eclipse Magnetics

As a global family of yeast and bakery ingredient companies, AB Mauri UK & Ireland is one of the largest producers and distributors in the world. The company must, therefore, ensure that the soya they process is free from any contamination that may be introduced into the process from the raw material, or during the milling process itself.

AB Mauri & Ireland has invested in nine Pneumag magnetic separators from Eclipse Magnetics to meet the latest food safety standards in its soya milling processes.

Fitted into pipelines that feed the soya beans into the process, the Pneumags provide protection against ferrous and para-magnetic contamination of dry powders and granulates, making them suitable for AB Mauri’s processing lines.

Contamination issues
AB Mauri& Ireland is vigilant regarding contamination issues, and therefore made a cautionary decision to replace the existing magnetic units in the milling system with upgraded units meeting the very latest food safety standards. A solution was required to protect the plant at the very beginning of the process, in addition to the replacement of nine magnets further down in the processing line to eliminate contamination.

Adrian Seeley, production supervisor at AB MauriUK & Ireland said: “Our pipelines are angled, so the units supplied by Eclipse provide the perfect solution to replace the existing magnets. Our operatives have commented on how much easier these new units are to clean and inspect each week”.

Uniform size
During milling, the soya beans are processed to a uniform particle size to produce flour. This is achieved by a sequence of breaking, grinding and separating operations. Nine Pneumag high intensity magnetic separators ensure that even the smallest ferrous contamination particles are extracted from pneumatically fed lines.

Each Pneumag unit contains a double row high intensity magnetic cartridge and is secured into its housing by quick release toggle clamps, which ensure even pressure is generated around the unique silicon-based metal-detectable seal.

The separators could be installed at any angle, from vertical to horizontal. A lockable tamper proof cover plate was also provided to ensure only authorised personnel have access to the unit.

Adrian continued: “We were delighted with the service provided by Eclipse Magnetics; from the initial site survey, right through to delivery.”
