Introduction

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.

He was also awarded a master degree in economics in 1990 and a Doctor of Economics in economic history in 1994, both from the Osaka City University. He worked for Asahi Chemical Industry Co. (Asahi Kasei) for 36 years. He moved to academics as aprofessor of clothing and natural poduct chemistry at the Kumamoto University (1993 - 1999) and then a professor of clothing and natural product chenmistry at the Nara Sangyo University (1999 - 2004). He published about 450 academic papers and book chapters. Among his numerous awards he received the Society Prizes from the Society of Fiber Science and Technology, Japan and the Society Prizes from the JJapan, respectivery and he is the 1998 Carothers Medalist (awarded by the Textile Institute, UK). He is a Chartered Chemist (UK), a Chartered Scientist (UK), and a Chartered Textile Technologist (UK).
