Background

Biography:

Tony Howes graduated from UQ in 1983 with a degree in chemical engineering, and after 6 months working on a novel fluid bed retort system for oil shale went to Cambridge, UK, where he worked with Malcolm Mackley as his first PhD student on what is now the “Oscillating Baffled Reactor”. His dissertation was awarded the 1988 Danckwerts-Maxwell prize for best thesis in that year. A postdoctoral year at Brown University working on patterns in fluid data sets was followed by 3 ½ years in ICI’s Corporate Colloid Science Group, where he worked on theory and application of a novel atomiser.

Since 1993 Tony has been at The University of Queensland teaching, supervising and doing research. His work (largely in collaboration with Bhesh Bhandari in Food Science) on sticky droplet spray drying has been extensively published and cited – at present Bhandari and Howes papers are in the top-10 most cited in Drying Technology, Journal of Food Engineering and International Journal of Food Properties.

Tony has also worked on a variety of other particle problems, including solid state fermentation, regimes in rotating drums and prilling. Following work on sticky mud particles he was heavily involved in local water quality issues, and sat on the Scientific Expert Panel of the Healthy Waterways Partnership in South East Queensland.

At UQ he co-ordinated an innovative programme where students are placed in industry for a research project, and actively reflect on their learning and interact with UQ staff while in industry. In 2008 he was nominated for a University Teaching Excellence Award for his efforts on this programme.

Research:

My research focus is on spray drying, especially of sticky or potentially sticky foods. With key collaborators (Prof. Bhesh Bhandari, UQ, A.Prof Benu Adhikari University of Ballarat) we have developed rules and understanding of the role of sugars, proteins and other additives on the drying of sugar rich foods, including fruit juices, honey and milk products.

My general interests are in the modelling and physical aspects of these systems.

Teaching and Learning:

Teaching: Engineering Thermodynamics (1st year)

Education Research: The role of Work Integrated Learning in the BE and ME programmes.

Projects:

  1. Spray drying at elevated temperatures
  2. API crystallisation modelling
  3. Role of proteins and additives in food spray drying
  4. Morphology development in spray drying

Available projects

  • A simple model for coastalwaterway management

    This research project is part of a larger Coastal Co-operative Research Centre project on the interface between modelling, monitoring and management in coastal waterways. Monitoring is essential for determining the water quality and ecosystem health of waterways. However, the are significant constraints on the design and operation of these programs due to cost and resource limitations. Furthermore, there are minimum requirements on the amount of data that is necessary to provide statistical confidence. This research project will aim to overcome some of these limitations by investigating the use of simple models for the design and interpretation of water quality monitoring data.

    Funds are available to top-up an APA or other scholarship by up to $5000 p.a. Importantly, the successful student will have an operating budget of up to $5000 p.a. and similar support for professional development, (to June 2006). The project involves close collaboration with the Queensland Environmental Protection Agency as well as a range of other stakeholders.

    Students will need an honours degree in a suitable field (Science, Engineering) and an interest in modelling and water quality issues.

  • Design of a PID controller for a drying rig

    We presently have apparatus which blows hot, dry air over a single droplet, and we obtain the drying kinetics of the drying through computer measurements of the droplet temperature and weight.

    We have a project which looks at improving the control of the in-coming air stream temperature and humidity, which at present is manually set by the user and monitored. In particular, we would like to look at using the data acquisition card and software in the computer to control the heating and humid air flow rates in order to perform this control.

    The project would suit a student interested in control or data acquisition.
