What action should be taken with a separator on the pasteurized side during diverted flow?

When a separator is on the pasteurized side during a diverted flow, it is crucial to valve it out of the system. This action is important because a separator on the pasteurized side can pose a risk of contamination to any pasteurized product if the flow is diverted. By valving it out, the separation process can continue without compromising the integrity of the pasteurized milk or dairy products. It ensures that only safe, pasteurized products are delivered to the consumer, adhering to safety regulations and maintaining product quality.

Keeping the separator in operation or merely monitoring it does not address the immediate risk of potential contamination, while regular cleaning is necessary for overall maintenance but does not mitigate the issues caused by a diverted flow. Therefore, valving out the separator is the necessary precaution that protects both the product and the consumer during such situations.
