Fluid flow in cleaning of closed processes

Issue 1 2006, Past issues  •  9 March 2006  •  Assistant Professor Bo Boye Busk Jensen and Associate Professor Alan Friis, Food Biotechnology and Engineering, BioCentrum-DTU

The efficiency of Cleaning-In-Place (CIP) procedures greatly depends on fluid flow (i.e. the motion of detergent and rinsing water). Thorough understanding of the physical action of fluid flow during cleaning allows for redesign of equipment and design of CIP procedures with respect to optimal cleaning characteristics. This article discusses the importance of fluid flow as an aspect of the cleaning processes. Computational Fluid Dynamics (CFD) is applied for prediction of areas inside closed process equipment, which are potentially difficult to clean. Finally, some commonly encountered questions on flow conditions during cleaning are discussed based on CFD results.

The basis for a common approach

Research continues in the area of hygienic engineering and design, particularly in innovative techniques using safe construction materials to develop functional as well as easily cleanable equipment for handling, processing and packing foodstuffs. This is the motivation behind the work of the European Hygienic Engineering & Design Group (EHEDG), which regularly publishes detailed guidelines and guidance on engineering aspects of food production.
