The textbook "Design, Development and Testing of Milk Pasteurization System" offers a comprehensive analysis of a newly developed pasteurization system for milk. It addresses the various testing conditions under which the system was evaluated, including raw milk temperatures and total milk solids. The authors document the specific test parameters, such as pasteurization temperature and process duration, as well as the methods for measuring the system's efficiency. By using a PLC system, important data such as temperature, pressure, and milk flow rates were recorded during operation. The statistical analysis of the results allows for the assessment of the efficiency and performance of the pasteurization process. This book is aimed at professionals and students in the field of food technology and engineering who are involved in the development and optimization of pasteurization processes.
