Advanced Drying Technologies For Foods

The goal of all drying research and development is to develop cost-effective innovative processes that yield high-quality dried products with less energy consumption and reduced environmental impact. With the literature on drying widely scattered, Advanced Drying Technologies for Foods compiles under one cover concise, authoritative, up-to-date assessments of modern drying technologies applied to foods. This book assembles a number of internationally recognized experts to provide critical reviews of advanced drying technologies, their merits and limitations, application areas and research opportunities for further development. Features: Provides critical reviews of advanced drying technologies Discusses the merits and limitations of a variety of food drying technologies Explains drying kinetics, energy consumption and quality of food products Reviews the principles and recent applications of superheated steam drying The first four chapters deal with recent developments in field-assisted drying technologies. These include drying techniques with the utilization of electromagnetic fields to deliver energy required for drying, for example, microwave drying, radio frequency drying, electrohydrodynamic drying, and infrared radiation drying. The remainder of this book covers a wide assortment of recently developed technologies, which include pulse drying, swell drying, impinging stream drying, and selected advances in spray drying. The final chapter includes some innovative technologies which are gaining ground and are covered in depth in a number of review articles and handbooks, and hence covered briefly in the interest completeness. This book is a valuable reference work for researchers in academia as well as industry and will encourage further research and development and innovations in food drying technologies.

Drying is an important unit operation used in the industry for processing and preservation of food products. Food industry always looks for cost effective and energy efficient drying techniques to commercially succeed in their ventures and to fulfill demand of high quality dried food products. Although a large volume of technical literature is available on drying of foods, it is still quite challenging for scientists and engineers to improve upon the existing drying systems and quality of the products. The book consists of 14 chapters detailing freeze drying, atmospheric freeze drying, swell drying, multi-flash drying, electro-hydrodynamic drying, pulse combustion drying, foam mat drying, ultrasound- assisted drying and fluidized bed drying. It also includes chapters which are commodity-specific such as mushroom drying, drying and roasting of cocoa and coffee beans. The degradation mechanism and kinetics of vitamin C degradation in fruits and vegetables, kinetics modeling of drying process for the recovery of bioactive compounds and energy calculation procedures for dryers is also covered which would be helpful to improve dryer operation and efficiency.

This book is an effort to present in a progressive and systematic form the basic knowledge required both for selection and technical design of appropriate drying systems. This book consists of 15 s; the first is dedicated to fundamental principles and basic terminology of drying followed by s offering a detailed description of different drying techniques and their applications. The challenge of developing advanced drying techniques for the food industry is followed in line with the demand for enhanced food quality and safety. Therefore, further s cover a comprehensive review of the latest developments in different drying technologies and locating the trends in future research and development. These s are written in a very easy to read and understandable language containing clear explanation of every concept and aspect of the same which can be used by undergraduate and graduate students as well as by faculty for teaching purposes. Recent literature is also compiled and discussed to assist researchers and scientists for clear understanding of the concepts in greater detail behind different types of drying techniques. The contributors in this book have worked extensively in respective areas of drying technology and their strong experience will greatly benefit the readers.

"Presents the most recent breakthroughs in thermal dehydration, drying, and dewatering. Emphasizes emerging equipment, innovative techniques, and cost-effective strategies for a variety of industrial and agricultural applications. Offers classification and selection criteria for new and advanced drying systems."

Drying is by far the most useful large scale operation method of keeping solid foods safe for long periods of time, and is of fundamental importance in most sectors of food processing. Drying operations need to be precisely controlled and optimized in order to produce a good quality product that has the highest level of nutrient retention and flavor whilst maintaining microbial safety. This volume provides an up to date account of all the major drying technologies employed in the food industry and their underlying scientific principles and effects. Various equipment designs are classified and described. The impact of drying on food properties is covered, and the micro-structural changes caused by the process are examined, highlighting their usefulness in process analysis and food design. Key methods for assessing food properties of dried products are described, and pre-concentration and drying control strategies are reviewed. Thermal hazards and fire/explosion detection and prevention for dryers are discussed in a dedicated chapter. Where appropriate, sample calculations are included for engineers and technologists to follow. The book is directed at food scientists and technologists in industry and research, food engineers and drying equipment manufacturers.

A guide to the major food drying techniques and equipment. It features technologies for meats, fruits, vegetables, and seafood. It covers microbial issues and safety. It includes designs for drying systems and manufacturing lines, and information on microbial safety, preservation, and packaging.

Although strides have been made to quantitatively explore micro-level structural changes during food processing using advanced technologies, there is currently no comprehensive book that details these developments. Therefore, the research community and related industries are not fully aware of the available techniques. Advanced Micro-Level Experimental Techniques for Food Drying and Processing Applications fills this gap. The book has been written based on the authors’ comprehensive knowledge and application of microimaging methods in the thermal processing of food. Features Describes the latest micro-level experimental methods primarily using microimaging techniques Presents detailed procedures of applying these techniques in food processing Highlights the current challenges of developing efficient and novel food processing systems Describes the fundamentals of water transport processes and associated morphological changes during thermal processing of food materials This book is written for researchers, chemical, food, and industrial engineers and advanced students seeking to solve problems of industrial food processing.

This book part 2 is one more effort to present in a progressive and systematic form the basic knowledge required both for selection and technical design of appropriate drying systems. This book consists of 14 chapters; which present comprehensive yet concise coverage of different novel drying techniques such as vacuum drying, refractance window dehydration technique, super critical drying, TES assisted solar drying etc. This book also covers recent technologies and trends in medicinal herb, fruit leather and protein drying as well as packaging of dehydrated foods. The mechanism of deliquescence and caking process involved in drying of foods, effect of drying on functional properties of foods have been added. Different control and safety systems required to improve dryer operation and efficiency and different approaches such as ANN and computer vision that can be used for modelling the drying process are also discussed. These chapters are prepared considering the convenience of understanding concepts and aspects of the topics especially by undergraduate and post graduate students as well as by faculty for teaching purposes. There are extensive references to earlier work as well as to recent publications to facilitate the researchers and scientists for their better understanding of the research area. Each of the invited contributors in this book has worked extensively in the respective area of drying technology and hence their strong experience in the form of chapter will benefit the readers.
