PCM-based Heat Exchanger for Pasteurization Process

The growing demand for energy-efficient and thermally stable pasteurization systems has intensified research into advanced heat exchanger technologies. PCM-Based Heat Exchanger for Pasteurization Process presents a systematic investigation into the integration of phase change materials (PCMs) within concentric double-tube heat exchangers to enhance thermal performance, energy utilization, and process reliability in food pasteurization applications. The book addresses the critical challenge of maintaining uniform temperature profiles during pasteurization while reducing energy consumption and operational fluctuations.

Beginning with the thermodynamic foundations of heat transfer and latent heat storage, the work develops a comprehensive framework for incorporating PCMs into conventional heat exchanger architectures. Detailed attention is given to the selection and characterization of suitable PCM materials, encapsulation strategies, and compatibility with food-processing environments. The study further examines active, passive, and compound heat transfer enhancement techniques, including the use of novel tube inserts and nanofluid-assisted flow augmentation, to improve heat transfer coefficients and thermal response.

Experimental analyses and performance evaluations demonstrate that PCM integration significantly improves thermal buffering, reduces peak energy demand, and enhances temperature uniformity during the pasteurization cycle. The book also discusses design optimization, material stability, and practical implementation considerations relevant to industrial-scale deployment. By combining theoretical modeling with applied engineering insights, this work provides a valuable reference for researchers, food process engineers, and thermal system designers seeking sustainable and high-efficiency pasteurization solutions.

Overall, the volume contributes to the advancement of smart thermal management in food processing by establishing PCM-enhanced heat exchangers as a promising pathway toward energy-efficient, reliable, and scalable pasteurization technologies.
