SYNOPSIS
Thermal drying operations are found in almost all industrial sectors and are known to consume 10-25% of the national industrial energy in the
developed world. With emerging economies rapidly industrializing various economic sectors, the energy consumed for thermal drying and the
resulting adverse environmental impact of the greenhouse gas emissions will inevitably rise with time. The most effective solution to this growing
problem is to develop and utilize highly energy-efficient drying technologies that will reduce net energy consumption and mitigate the
environmental impact. Over the last three decades much progress has been made in this area. This talk will present an overview of the causes for
inefficiency in industrial drying and provide a summary of numerous new attempts to enhance the performance of drying technologies in diverse
industries. In particular, advantages of heat pump-assisted drying, superheated steam drying, pulse combustion and pulse combustion-assisted
drying, utilization of waste heat and renewable energy for drying etc will be discussed along with selected case studies. In addition, the efficiencies
of dryer systems can also be improved by multi staging, combining different types of dryer and by intermittent and multi-mode heat inputs for
batch dryers. With over 400 types of dryers used to dry some 50,000 materials at various production scales, it is necessary to examine the problem
at the fundamental level of dehydration.
