What does the term "regeneration" refer to in pasteurization?

The term "regeneration" in the context of pasteurization refers specifically to the process of utilizing the heat from the outgoing pasteurized product to preheat the incoming product before it undergoes pasteurization. This method is crucial because it increases energy efficiency in the pasteurization process. By reclaiming heat from the already heated liquid, it minimizes the energy required to raise the temperature of the incoming product, contributing to more efficient operation and less energy consumption.

This method not only helps in saving energy but also supports maintaining the temperature required for effective pasteurization, thus ensuring the product is sufficiently treated to eliminate harmful microorganisms without compromising its quality.
