SYNOPSIS There are over 400 dryer types cited in the technical literature although only about 50 types are commonly found in practice. As such proper selection of dryer is an important topic to industrial drying. Dryer selection has long been practiced as an art rather than science depending more on prior experience and vendors’ recommendations. As drying technologies have evolved and become more diverse and complex, this has become an increasingly difficult and demanding task for the non-expert. Further, the task is exasperated by the need to meet stricter quality specifications, higher production rates, higher energy costs and stringent environmental regulations. This talk intends to give an introduction to industrial drying and briefly discuss the classification of industrial dryers. The key classification criteria for industrial dryers will be discussed as well as selection criteria. It is important for an engineer responsible for selection of a dryer or a drying system to be aware of what is available in the market, what the key criteria are in the selection process and thus arrive at alternative possibilities before going to vendors of such equipment for comparative quotes. It is time and effort well spent since the cost of incorrect selection can be very high. It was reported that over 80 percent of major chemical companies in Europe – each using over 1000 dryers in their production facilities – made errors in selecting dryers. What is optimal choice in one location at one point in time may be a wrong choice for another geographic location some years later. Prior use is a definite help but not the only criterion to be used in selecting drying systems. BIODATA OF SPEAKER Engr. Dr Law Chung Lim is an Associate Professor with the University of Nottingham, Malaysia Campus. He is also a chartered engineer and a chartered scientist. Engr Law has more than 11 years of experience in R&D work on industrial drying. He published more than 20 journal papers, 10 articles and presented more than 80 conference papers and majority of the papers are related to drying. In addition, he has contributed a chapter on “fluidized bed drying” in Handbook of Industrial Drying, an encyclopedia chapter “Drying” in the Encyclopedia of Industrial Biotechnology: Bioprocesses, Bioseparation, and Cell Technology and several book chapters in Guide to Industrial Drying. Dr. Law has experience in the design of baffled fluidised bed dryer and 2-stage cross flow fluidised bed dryer. He has recently designed and fabricated two variants of heat pump dryer, namely hybrid heat pump dryer and intermittent heat pump dryer. He has delivered keynote speeches on various aspects related to industrial drying, namely new developments and latest advancement in food drying and energy aspect in drying. Dr. Law’s current research focus is in the area of preservation of active ingredients such as antioxidants and vitamins in local fruits, agricultural products and herbal products. Engr. Dr. Ramlee Karim FIEM, PEng Chairman Chemical Engineering Technical Division, IEM
