What is the purpose of the vat pasteurizer leak protector outlet valve?

The purpose of the vat pasteurizer leak protector outlet valve is to prevent product from leaking around the valve core. This function is crucial in maintaining product integrity and ensuring food safety. When the valve is functioning correctly, it seals properly, preventing any undesired leakage of the pasteurized product. This is particularly important in the pasteurization process, where maintaining the right conditions is vital for ensuring that harmful pathogens are eliminated while preserving the quality of the product.

The other options do not align with the operational requirements of a leak protector outlet valve. Increasing the temperature of the liquid or keeping the valve open at all times would not support the primary goal of controlling product safety and quality. Allowing product to leak would compromise hygiene and safety standards, so that is also not an appropriate function of this valve.
