What is the purpose of the jacket on a wall pasteurizer?

The jacket on a wall pasteurizer serves the essential function of holding the transfer medium for heating and cooling. This design is crucial because it enables the pasteurizer to effectively regulate the temperature of the product being treated. The jacket is typically filled with a fluid—often water or steam—that circulates around the product-containing vessel. This circulation facilitates the uniform heating or cooling of the product, ensuring that pasteurization occurs efficiently and effectively.

Maintaining the correct temperature is vital for achieving desired microbial reductions while preserving the quality of the food being pasteurized. This function of the jacket is integral to the operation of wall pasteurizers, as it directly impacts the effectiveness and safety of the pasteurization process.
