Magnetic Appeal for Bakery Applications

Magnattack Global has developed a unique Spherical Magnet system designed for installation in pneumatic transfer lines and commercial bakery flour intakes to reduce risk of metal contamination in the final product.

Metal fragment problems are very common to flour milling due to the high impact machinery used. The 10-12,000 gauss Spherical Magnet System provides large bakery operations with greater assurance that metal fragments prior to processing are removed from their incoming flour and ingredients to reduce the risk of metal contamination on the final product. As its name suggests, the system comprises a high-intensity Spherical Magnet which has been designed for minimal impact on blower and rotary valve amp readings.

"Although flour mills and ingredient suppliers usually have their own magnet systems in place to remove metal from flour, adequate metal extraction can be limited at bulk out loading points due to high tonnage rates and outputs",says Magnattack General Manager Kevin Baker.

The use of this system in their intakes gives commercial bakeries the confidence and assurance of proven metal fragment control on their incoming flour prior to further processing.

"Flour mills can only do so much, but because lower volumes of flour are being blown into a bakery storage silo, bakeries are in an excellent position to provide the last line of defense against metal fragments before they enter the factory."


Although the system is not new and has been in use already in some bakeries for over a decade, it is not yet widely in use in the bakery industry, Baker says, which means many are missing out on an opportunity to offer a cleaner, safer product and further reduce metal contamination risks.The system has also been extensively inspected by the Centre of Bulk Solids at the UOW, a renowned bulk solids consultation centre, with results showing little to nil impact on bulk density.

The magnet is an extremely aerodynamic design which, unlike bar magnets and bullet magnets in blowlines, does not allow the product to impinge and impact on an obstruction in the flow of product - meaning the likelihood of bulk density breakdown and particle breakage is significantly reduced and potentially removed.

"This is one of very few magnets that really work in pneumatic transfers and they have been proven over many years. The first small spherical magnet we made for a QLD bakery is working just as well as it did when we installed it 18 years ago."

The Spherical Magnet design also carries International HACCP Endorsement and conforms to International Magnet Standard 0909MAGSEP 1-2010.

The 12,000 gauss Spherical Magnet has also proven itself in use for other pneumatic conveyed dry product processes, such as dairy powders, ingredients, dry mixes and much more. USDA accepted models are now available.

Like all Magnattack equipment, the Spherical Magnet has been designed, researched, developed and manufactured in Australia without use of inferior imported or non-compliant magnetic elements or components.
