Surface Modification of Spray-Dried Powders By Surface-Active Proteins. Internal wall deposits in spray dryers lead to product degradation and pose fire hazards. This situation has limited the manufacturing of high value bio-food powders by the Australian bio-food and dairy industry, which exports 13% of the milk powder in the world.

Internal wall deposits in spray dryers lead to product degradation and pose fire hazards. This situation has limited the manufacturing of high value bio-food powders by the Australian bio-food and dairy industry, which exports 13% of the milk powder in the world. The specific economic benefits to Australia from this project arise from innovative surface modification of powder particles by proteins, development of scientific instruments and predictive tools based on Computational Fluid Dynamics (CFD). These outcomes will lead to production of free flowing powders from bio-food materials.Read moreRead less
Towards New Functionality in Dairy Ingredients. The Australian dairy industry plays a significant part in the nation’s economy, with almost $3 billion in export revenue in 2016-2017.

Powdered dairy products extend shelf life and ease of transport, with >20% annual growth in premium products, such as milk protein concentrates and infant formula powders. This project aims to support the development of value-added dairy powders by investigating the impact of a novel high pressure processing technology in enhancing the properties of dairy powders and/or introducing new functionality. Successful outcomes will help expand the offering of high value dairy ingredients and thus increase the global competitiveness of Australian dairy manufacturing.Read moreRead less
Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description ....Soft solids rheology and filled elastomeric networks.

Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description of filled soft viscoelastic solids, which include compressibility and yielding - two important new features.Read moreRead less
Novel coding and decoding in suspension arrays for accelerated biomolecular discovery and personalised medicine. This project will establish an advanced multiplexing technique to rapidly analyse complex biological mixtures, such as cell lysates, food samples or body fluids. It will enable the analysis of not tens, but thousands or more distinctive molecular targets in a single test. This will build the foundations for future generation bioassays, paving the way to emerging personalised medicine. ....Novel coding and decoding in suspension arrays for accelerated biomolecular discovery and personalised medicine.

It will enable the analysis of not tens, but thousands or more distinctive molecular targets in a single test. This will build the foundations for future generation bioassays, paving the way to emerging personalised medicine. This will lead to new personal diagnostics tools for rapid genotype profiling, to better tailor therapy to the individual patient's specific characteristics. As well as the potential to improve health outcomes, the project will generate significant intellectual property and the opportunity for development of new diagnostic instrumentation in Australia.Read moreRead less
Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this info ....Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this information to predict their growth behaviour. Special attention will be given to the effects of strain-rate and particle morphology in granulation mechanics. Improvements in granulation technology will be of great benefit to food, pharmaceutical, agricultural, explosives and mining industries and opens the way to 'designer granulation' for special purposes.Read moreRead less

Dynamic input adjustment to improve the stability of transient swirling flows in spray dryers. This project will use leading-edge numerical techniques to advance the science of flow stabilisation using dynamic flow modulation techniques. Improved sustainable processing will be enabled using this flow modulation in spray dryers to reduce processing problems due to the depositon of particles on dryer walls.
Mullins-type effects in soft filled viscoelastic solids. Bread dough is made in vast quantities daily, and improvements in processing,especially sheet rolling,are needed,and to enable this we propose to create a novel mathematical description of the material. Also, wheat breeding cycles can be drastically shortened by using knowledge of dough rheology, since baking quality is closely linked to rheology. The mathematical framework can then be applied to other filled viscoelastic systems, and work ....Mullins-type effects in soft filled viscoelastic solids.

Also, wheat breeding cycles can be drastically shortened by using knowledge of dough rheology, since baking quality is closely linked to rheology. The mathematical framework can then be applied to other filled viscoelastic systems, and work on liquid crystals may be used to develop artificial muscle material, once their rheological description and behaviour are known.Read moreRead less
Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled.

A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project will use state-of-the-art experimental and computational techniques to gain a fundamental understanding of this phenomenon and will develop a validated wall deposition model to predict when and to what extent this process occurs, to give higher throughputs and/or more efficient systems.Read moreRead less
