Simple update to IEM Members or those who are practicing Engineering in MALAYSIA...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.
