The design and installation of CIP systems in large food processing plants requires specialized experience in pipe flow, sanitation, processing operations, and process control.
The CIP system involves the following sequential operations: 1) Pre-rinsing with cold (soft) water; 2) alkali wash (supplemented with sodium hypochlorite); 3) intermediate water rinse; 4) acid rinse; 5) final water rinse; and 6) rinse with sanitizing solution (sodium hypochlorite) or flushing with hot (90 °C) water.
