The viscosity of the cream and the requirement for hygienic process equipment, however, meant that relatively simple flash evaporation technology had been used as the standard technology. Trials with the SCC showed that not only could the SCC handle the increased viscosity of the cream but that the steam usage to remove the volatile compounds was reduced by 80% compared to the flash evaporation process. Moreover the ability to clean in place (CIP) effectively in an environment where hygienic operation is critical was demonstrated. SCC plants in the dairy industry were also required to be remotely operated and integrated into the rest of the process.
