Professor Langrish is a world leader in drying technology, particularly spray drying and the drying of timber. His work, with Professor Fletcher, on transient flows in spray dryers, has uncovered new types of flow instabilities that are fundamental to improving practical outcomes in reducing the deposition of particles on spray dryer walls. This achievement is scientifically significant because it applies advanced computational modelling and physical understanding to the solution of important and common industrial process engineering problems.
His recent work to develop crystallization in drying has the potential to improve the use of resources by combining crystallization and drying, which traditionally are done separately, into one operation. The industrial significance and application of this work can be judged from the improvements in productivity and quality that have been achieved for local dairy and timber industries.
Professor Tim Langrish's research activities span a wide range of areas, but share a common goal of improving our quality of life. The means by which he is working to achieve this include reducing the recurrence of cancer, improving nutrition and lowering energy consumption in industry.
"I work in a range of areas including food process engineering, drying technology, energy and energy quality, solar kilns, timber drying and spray-drying technologies.
"One aspect of my research aims to assist in reducing cancer recurrence by improving the quality of foods, including adding extracts from citrus fruits to cereals. Our treatment of acute cancer issues is increasingly effective but cancer recurrence remains a significant concern, which this project is working to address.
"I am also working on new crystallisation and drying technologies that will enable us to create powdered fruit juices and milks with improved storage stability. This will allow these products to be made available in areas without access to refrigerated transport, improving the health of people in those areas, and is also a very important development in the Australian manufacturing industry.
"Other projects involve making salt that tastes saltier than normal salt, so that people can reduce their salt intake while retaining the same perception of saltiness; assisting Australian manufacturers of solar kilns to maintain their world lead in solar kiln design; and reducing energy use in industry, decreasing costs and enabling industries to maintain their competitive edge.
"The common objective of all of my work is to improve quality of life.
"I've been working in this field for the past 25 years. A strong and broadly based academic institution like the University of Sydney is essential to maintaining steady progress in this kind of work, whose complexity requires multidisciplinary and multi-faceted approaches to be taken. The University of Sydney is the best environment for providing this support."
