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.

The second part comprises of 14 chapters presenting comprehensive yetconcise coverage of different novel drying techniques such as vacuum drying, refractance window dehydration technique, super critical drying, TES assisted solar drying etc. This volume 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 modeling the drying process are also discussed.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 peer reviewedchapter will benefit the readers. Chapter are written in a very easily 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 in detail to assist researchers and scientists for clear understanding of different types of drying techniques.

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 chapterss; the first is dedicated to fundamental principles and basic terminology of drying followed by chapters 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 chapters cover a comprehensive review of the latest developments in different drying technologies and locating the trends in future research and development. These chapters 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.
