Gearboxes for food industry
Designed and certified according to EHEDG (European Hygienic Engineering & Design Group) rules to ensure optimal material resistance and cleanability, hygienic design gearboxes from Treotham meet the most stringent requirements of the food and pharmaceutical packaging industries.
With their coaxial, dynamic planetary gearheads available in several different performance classes, the gearboxes provide robustness, resistance and cleanability.
The gearbox housing is free of edges and gaps that could provide a breeding ground for bacteria or microorganisms or act as dirt traps.
Just like its adapter plate, the gearbox housing is manufactured from stainless steel 1.4404 / AISI 316L – a low carbon steel that is approved by the US FDA (United States Food & Drug Administration) for food contact that offers high resistance to cleaning and washdown fluids such as disinfectants containing hypochlorite or chlorinated alkaline foam cleaners.
All stainless steel surfaces of the gearboxes are electro-polished with a roughness of either 0.8 μm Ra, as stipulated for food processing applications or 0.4 μm Ra, which is the accepted standard for the pharmaceutical industry.
This surface treatment minimises the risk of product residue and adhesion.
