Dairy pasteurization is a critical process in the milk production industry, involving the heating of milk to a specific temperature to eliminate pathogens and extend shelf life. This process is facilitated by heat exchangers that efficiently transfer heat to the milk without direct contact with the heating medium. Heat exchangers play a pivotal role in ensuring the pasteurization process is both energy-efficient and effective, maintaining the milk's nutritional value while securing food safety standards. Their application in dairy pasteurization underscores the necessity for reliable equipment in safeguarding public health.
