Abstract

The hygienic state of process surfaces in food production plants crucially affects the quality of food products. Hygiene is important everywhere but fermentation processes where specific microorganisms are used to ferment nutritious raw materials into high quality foods requires special attention. The consequence of contamination of a fermentation can be fatal to the product quality and large batches might be discarded. Therefore hygienic requirements must be included in the design of the process as well as when performing the cleaning procedure. Fluid flow plays an important role in both production and cleaning. Specific hydrodynamic parameters have been proved to control cleaning in closed process systems. The work pertains extension of flow modelling to be applicable for improvement of the hygienic state of food process tanks. The present case study is limited to fermentation tanks for dairy and brewery applications.
