Magnattack has developed a unique magnet system designed for installation in pneumatic transfer lines and commercial bakery flour intakes.
Metal fragment problems are very common to flour milling due to the high impact machinery used.
The 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 risk of metal contamination on final product.
As its name suggests, the system comprises a high intensity 12,000 gauss 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, according to Baker.
“Flour mills can only do so much, but because lower volumes of flour is being blown into a bakery storage silo, bakeries are in an excellent position to provide a last line of defence against metal fragments before they enter the factory.”
Although the system is not new, and has been in use already in some bakeries, it is not yet widely used 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 University of Wollongong, 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 in blowlines, doesn’t allow product to impinge and impact on an obstruction in the flow of product, meaning the likelihood of bulk density breakdown and particle breakage is potentially removed,” says Baker.
“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 Queensland bakery is working just as well as it did when we installed it 18 years ago. They’re very impressed.”
The spherical magnet design also carries an International HACCP Endorsement conforming to International Magnet Standard 0909MAGSEP 1-2010.
The 12,000 gauss Spherical system has also proven itself in use for other pneumatic conveyed dry product processes, such as dairy powders, (with a USDA accepted unit now available) ingredients, dry mixes and much more, Baker says.
Like all Magnattack equipment, the 12,000 gauss Spherical system has been designed, researched, developed and manufactured in Australia without use of imported or non-compliant magnetic elements or components.
