Why must both valves of the flow diversion device pulse independently during CIP?

The requirement for both valves of the flow diversion device to pulse independently during Clean-in-Place (CIP) is fundamental for ensuring that the cleaning solutions reach all areas of the system, including the leak detectors and flow diversion lines. When valves operate independently, it allows for a thorough cleaning process, ensuring that every part of the system is adequately exposed to cleaning agents. This independent pulsing helps to avoid any stagnant areas where residual product could remain, which could otherwise lead to contamination or inadequate cleaning.

Maintaining effective cleaning practices is crucial in pasteurization processes where food safety and product quality are paramount. Implementing this procedure ensures that all components, including those that might not be directly involved in the product flow path, receive the necessary cleaning attention to minimize the risk of contamination post-cleaning.

While even heating and maintaining system pressure are important in other aspects of pasteurization operations, they are not directly related to the purpose of the flow diversion device during CIP. Similarly, reducing backflow is a consideration in system design but does not specifically address the necessity for independent pulsing during cleaning processes.
