The target set out by SUEZ: increase the efficiency of Yeo Valley’s custard production line by providing an alternative solution to cleaning and product recovery.
Ice Pigging for the Food and Beverage industry can be adapted to give maximum benefits depending on the characteristics of the product in pipe.
Ice has a significantly more effective cleaning power compared to water flushing and has the ability to navigate bends, restrictions, valves and most obstructions that limit the use of solid pigs.
Ice Pigging is often considered a very effective pre-clean prior to a chemical CIP process. Ice Pigging can remove up to 99% of all product from a line, resulting in a major reduction in effluent, a fast and much more effective CIP and a much better chance of product recovery.
Compared to the usual flushing process used on production machinery, Ice Pigging was able to recover an additional 50 litres of product per run and produced less effluent for disposal.
SUEZ’s Ice Pigging machine also helped to reduce downtime due to shorter duration of cleaning process and reduced the use of CIP chemicals which further benefited the environment.
