Heat Transfer In Food Processing

Heat Transfer is important in food processing. This edited book presents a review of ongoing activities in a broad perspective.

This long awaited second edition of a popular textbook has a simple and direct approach to the diversity and complexity of food processing. It explains the principles of operations and illustrates them by individual processes. The new edition has been enlarged to include sections on freezing, drying, psychrometry, and a completely new section on mechanical refrigeration. All the units have been converted to SI measure. Each chapter contains unworked examples to help the student gain a grasp of the subject, and although primarily intended for the student food technologist or process engineer, this book will also be useful to technical workers in the food industry

Computational methods have risen as a powerful technique for exploring the system phenomena and solving real-life problems. Currently, there are two principle computational approaches for system analysis: continuous and discrete. In the continuous approach, the governing equations can be obtained by applying the fundamental laws, such as conservation of mass, momentum, and energy over an infinitesimal control volume. On the other hand, the discrete approach concentrates on mimicking the molecular movement within the system. Both approaches have pros and cons, and continuous development and improvement in the existing computational methods are ongoing. Advanced Computational Techniques for Heat and Mass Transfer in Food Processing provides, in a single source, information on the use of methods based on numerical and computational analysis as applied in food science and technology. It explores the use of various numerical/computational techniques for the simulation of fluid flow and heat and mass transfer within food products. Key Features: Explores various numerical techniques used for modeling and validation Describes the knowhow of numerical and computational techniques for food process operations Covers a detailed numerical or computational approach of the principles of heat and mass transfer in the food processing operation Discusses the detailed computational simulation procedure of the food operation Recent years have witnessed a rapid development in the field of computational techniques owing to its abundant benefit to the food processing industry. The relevance of advanced computational methods has helped in understanding the fundamental physics of thermal and hydrodynamic behavior that can provide benefits to the food processing industry in numerous applications. As a single information source for those interested in the use of methods based on numerical and computational analysis as applied in food science and technology, this book will ably serve any food academician or researcher in learning the advanced numerical techniques exploring fluid flow, crystallization, and other food processing operations.

This comprehensive book is a valuable and readable reference text and source for anyone who wishes to learn about food cooling applications and methods of analysis of the heat transfer during these applications.

This new edition discusses the physical and engineering aspects of the thermal processing of packaged foods and examines the methods which have been used to establish the time and temperature of processes suitable to achieve adequate sterilization or pasteurization of the packaged food. The third edition is totally renewed and updated, including new concepts and areas that are relevant for thermal food processing: This edition is formed by 22 chapters—arranged in five parts—that maintain great parts of the first and second editions The First part includes five chapters analyzing different topics associated to heat transfer mechanism during canning process, kinetic of microbial death, sterilization criteria and safety aspect of thermal processing. The second part, entitled Thermal Food Process Evaluation Techniques, includes six chapters and discusses the main process evaluation techniques. The third part includes six chapters treating subjects related with pressure in containers, simultaneous sterilization and thermal food processing equipment. The fourth part includes four chapters including computational fluid dynamics and multi-objective optimization. The fifth part, entitled Innovative Thermal Food Processing, includes a chapter focused on two innovative processes used for food sterilization such high pressure with thermal sterilization and ohmic heating. Thermal Processing of Pa ckaged Foods, Third Edition is intended for a broad audience, from undergraduate to post graduate students, scientists, engineers and professionals working for the food industry.

In food processing, thermal operations are the most common and conventional methods for obtaining and treating different products. This book covers basics and advances in thermal processing of food.

Food Processing: Advances in Thermal Technologies is aimed at graduate students and professionals in food engineering, food technology, and biological systems engineering

Specifically developed for food engineers, this is an in-depth reference book that focuses on transport phenomena in food preservation. First it reviews the fundamental concepts regarding momentum, heat, and mass transfer. Then the book examines specific applications of these concepts into a variety of traditional and novel processes and products.

Thermal technologies have long been at the heart of food processing. The application of heat is both an important method of preserving foods and a means of developing texture, flavour and colour. An essential issue for food manufacturers is the effective application of thermal technologies to achieve these objectives without damaging other desirable sensory and nutritional qualities in a food product. Edited by a leading authority in the field, and with a distinguished international team of contributors, Thermal technologies in food processing addresses this major issue. Part one of the collection begins with reviews of conventional retort and continuous heat technologies. Part two then looks at the key issues of effective measurement and control in ensuring that a thermal process is effective whilst minimising any undesirable changes in a food. There are chapters on temperature and pressure measurement, validation of heat processes, modelling and simulation of thermal processes, and the measurement and control of changes in a food during thermal processing. The final part of the book looks at emerging thermal technologies which becoming more widely used in the food industry. There are chapters on radio frequency heating, microwave processing, infrared heating, instant and high-heat infusion, and ohmic heating A final chapter considers how thermal processing may be combined with high pressure processing in producing safe, minimally-processed food products. Thermal technologies in food processing provides food manufacturers and researchers with an authoritative review of thermal processing and food quality.
