24.09.2018 Powdered gluten protected from metal contamination

Eclipse Magnetics, Sheffield, UK, has installed a bespoke double row magnet at the Corby, Northamptonshire plant of Roquette, a global leader in plant-based ingredients and a pioneer of new vegetal proteins. Currently operating in over 100 countries, the company has a turnover of around 3.3 billion euros and employs 8400 people worldwide. As a commodity ingredient, powdered gluten is often used as an additive in baking to add elasticity to flours that would otherwise be low in gluten, such as whole wheat flour or rye.

The magnet system incorporates magnetic bars, which are not only withdrawable, but also easy to clean. A catchment tray was also included to effectively contain any residual gluten which can be dislodged from the bars as they are withdrawn for cleaning. The unit has been installed at the end of the process, before the product is filled into tankers or flexible packaging, and the residual product captured by the magnets is collected in clearly marked bags and disposed of.

Ian Aunger at Roquette said: “The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean. Although the design of the magnet system was not easy because of the limited headroom and space, Eclipse Magnetics were willing and able to meet all of our design criteria.” Eclipse often supplies custom designed and engineered solutions to suit specific requirements, as is the case with Roquette’s application. All product contact parts are manufactured using food quality 316 grade stainless steel, are fully sealed, and supplied with test certificates.
