Foreword to the First Edition
The Handbook of Industrial Drying fills an important need and is of immeasurable value in the field of drying. Academics, students, and industry people— from sales to research—can learn much from the combination of principles and practices used throughout. The presentation of principles does not overwhelm the coverage of equipment and systems. More appropriatetheories will develop as a result of the description of equipment and systems. For example, a description of dryers, particularly industrial dryers, is lacking in many research articles; this handbook provides such information. The authors have distilled much information from extensive literature to provide generic information as contrasted with details of a specific drying system of a particularmanufacturer. The users can extrapolate the use of drying systems, by design and management, to a variety of products. As a special feature, a complete listing of books written on the subject of drying is included. The authors, a blend of students, faculty, and those in industry, represent experience with different kinds of drying systems, different applications of principles, and different products. Thebook provides excellent coverage of the cross-disciplinary nature of drying by utilizing well-known authors from many countries of the world. Dr. Mujumdar and his associates have assembled an excellent up-to-date handbook. The common thread throughout the book is the movement of heat and moisture as well as the movement and handling of products. Also included are instrumentation, sensors, andcontrols that are important for quality control of products and efficiency of operation. The emphasis on the design of equipment to expedite these processes in an economical manner is appropriate and useful. The word handbook is sometimes used disparagingly to describe a reference for quick answers to limited questions or problems. In that sense this book is more than a handbook—the knowledge baseprovided permits the user to build different systems for products other than those covered. Carl W. Hall

Foreword to the Second Edition
The second edition of the Handbook of Industrial Drying continues the tradition of the editor and the publisher as international leaders in providing information in the field ofindustrial drying. The authors are knowledgeable of the subjects and have been chosen from among the world’s authorities in industry, academia, government, and consulting. Some 50 authors from 15 countries have written 43 chapters plus 3 appendices. There are 21 new chapters, plus 2 new appendices. All chapters have been updated or revised. There is over 60% new material, making this editionpractically a new volume. The mark of an outstanding handbook is that it provides current information on a subject—in this case multidisciplinary in nature—understandable to a broad audience. A balanced approach of covering principles and practices provides a sound basis for the presentations. Students, academics, consultants, and industry people can find information to meet their needs. Researchers,designers, manufacturers, and sales people can benefit from the book as they consider elements or components related to drying as well as the system itself. New material has been added to provide the latest information on minimizing environmental impacts, increasing energy efficiency, maintaining quality control, improving safety of operation, and improving the control of drying systems. New sectionsor chapters have been added to cover in detail microwave drying; infrared drying; impinging stream dryers; use of superheated steam and osmotic dehydration; and drying of biotechnological materials, tissue and towels, peat, coal, and fibrous materials. The information in this book can be categorized as product related, equipment related, and the relationship between the two—the system of drying....
