A special HP impregnation of the fabric in the driving surface of the belts acts as insulation and further protects against bacterial infiltration.” Another innovative, patented technology from Intralox is the company’s ThermoDrive the first to combine the best features of modular plastic and traditional flat belts. easy cleaning ThermoDrive belts are homogeneous thermoplastic with 100 per cent closed surfaces, making them well suited for hygienic food-processing applications. At first glance, they may appear to be traditional flat belts. What makes them significantly better is the patented ThermoDrive positive drive system. Unlike traditional flat belts, these belts drive on sprockets like a modular plastic belt and are not under tension, enabling easy lifting for conveyor cleaning and solving nearly all traditional flat belt problems. Intralox offer ThermoDrive technology for dough handling, which boasts numerous benefits, including improving sanitation, extending belt life and decreasing maintenance. With a smooth, scraper-friendly, non-stick Knowing that hygiene is increasing in conveying surface and zero-tension, no-slip, importance, Chiorino launched a new belt that has sprocket-driven operation, patented ThermoDrive met and exceeded the rigorous criteria laid down by belting eliminates many of the operational issues European Food Directives. This includes only using associated with using flat belting in dough handling chemicals in the production of their conveyor belts applications. that are authorised to be in contact with foodstuffs, Cambridge’s Hayden, commenting on the and keeping the migration levels of these chemicals company’s Duraflex range, said they provide down to an absolute minimum. hygienic and sanitary applications. These polyurethane coated products embrace “These belts are the strongest available with the the HACCP concept, said Stephen Midwinter, sales widest unobstructed openings that allow for simple, manager, and they form basis for more development in-place cleaning.

He said the belts do not contain any biocide “Because these belts are designed for sanitation additives that could migrate from the surface and and a long service life, metal belts are a costcontaminate products being conveyed. effective solution in the baking industry. From “This is achieved through a production technique longevity to hygiene, metal belts can handle all food processing demands, from start to final product.” Sandvik states the thermal properties of a steel belt – whether solid or perforated – make it ideally suited to an application where temperatures can reach as high as 400C; excellent heat transfer and thermal conductivity ensure good baking performance and consistent product quality, while the belt itself remains stable. “Equally important is the ability to maintain the highest standards of hygiene and this is another area where steel belts score highly,” concludes Lundgren. n chiorino’s belts meet european safety standards. kaak’s plastic belts are widely used in the food industry. “Designed for hygiene and long service, metal belts are a costeffective solution.” 18 spring 2013 BISCUIT WORLD
