Advances in Welding for Sanitary Designs

June 25, 2004 --The Annual Meeting of 3-A Sanitary Standards Inc. was held in Milwaulkee, Wisconsin, U.S.A., on May 17-21, 2004. The first day of this 3-day meeting, was entirely devoted to challenges in food equipment design and food sanitation. The program included six speakers from industry and concluded with a panel discussion on sanitary design and plant inspections.

The keynote speaker, Virginia Deibel, PhD, COE, Brain Wave Technologies, Inc. discussed biofilms in the food industry. Biofilms are of particular concern to the food processor because of the adverse affect on the finished product, e.g. decreased shelf life, bloated packages, off odors to name a few. The formation of biofilms is strongly influenced by the food equipment design and surface condition of the equipment. Biofilms form more readily where there are equipment scratches or rough surfaces and the need for care in fabricating stainless steel equipment or components of any other material is of primary importance.

The other presentations offered support on the importance of good sanitary design, construction and cleaning practices to remove biofilms. Richard E. Avery, consultant to the Nickel Institute, made a presentation on "Advances in Welding for Sanitary Designs" with emphasis on making quality welds that would be most resistant to the formation of biofilms.
