What is the function of the flush delay on a dual stem flow diversion device?

The function of the flush delay on a dual stem flow diversion device is to manage the timing between valve movements during forward flow. This mechanism is crucial in ensuring that any contaminants or residues from the previous cycle are flushed out properly before the product continues through the system. By controlling the timing of valve movements, the flush delay helps to maintain product quality and safety, ensuring that only safe, properly pasteurized product is routed to the packaging process.

The flush delay is particularly important because it ensures that there is adequate time for the system to clear before switching flow directions or beginning a new batch. This prevents any potential cross-contamination and ensures compliance with safety standards governing pasteurization processes.
