Public Funding for Tetra Pak Processing UK Limited

The heat exchangers used in raw milk pasteurisation suffer from progressive fouling and must be cleaned regularly. Cleaning is the main cause of non-productive energy consumption in a dairy, and the water and chemicals used in cleaning must be handled as effluent. This project aims to increase the time between cleans without affecting the microbiology or taste of the milk by developing a full understanding of the factors which affect deposit formation and balancing these against novel ways to remove or reduce the deposit. Through advanced mathematical modelling, new holistic strategies will be developed and subsequently tested on pilot and full-scale milk pasteurisation plants. A reduction in energy, water and chemical usage will follow from a successful project outcome.
