This book provides a standardized analytical method for drying a single fine particle (disk). It is, however, expected that by the use of these results, process design and operation procedures for industrial dryers such as fluidized beds which deal with particle assembly, convective types for bulk materials and so on could be developed in industry as well as in academic research. The author recommends the present book to not only engineers and researchers who are engaged in drying processes but also those with a wide variety of backgrounds in industry as well as college students in engineering.
