Center for hygienic design

The project Hygienic Design is a co-operation between the Technical University, research institutes and partners from the food processing and biochemical industry. Biofilm formation is a major concern in food processing industry. It is aimed to improve surface material hygienic lifetime by selecting surface materials in combination with cleaning chemicals and cleaning procedures. Department of Manufacturing Engineering and Management is involved in development of materials with low bioadhesion (resistance towards biofilm formation), designed on the basis of effect of surface structure, surface chemistry, and cleaning properties. The work also includes development of quantitative techniques for examination of bioadhesion as well as corrosion. Studies have been made of the effect of surface finish of stainless steel 316 on adhesion of bacteria in stagnant media and under flow as well as field tests.
