| Abstract: | The chocolate processing industry offers a constantly growing variety of products. With a limited number of production lines in combination with complex components (e.g. shell-and-tube heat exchangers), product change is a critical step to ensure consumer safety and product quality. Product changes are achieved by displacing the product with a follow-up product. Within the scope of this work, the development of a test rig for the replication of industrial flushing processes is presented. The complexity of heat exchangers is reduced to a simplified double-pipe heat exchanger. A standardized methodology for operating and evaluating the experimental tests is presented. In combination with a short review of similar published investigations, this work contributes to the expansion of the experimental database on flushing processes. Parameter studies on the influence of the process temperature and order of flushing fluids are used to validate a numerical simulation model of the process. [ABSTRACT FROM AUTHOR] |
