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. The proposed project wi ....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. 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
Production of Concentrated Fresh Milk Products. This project focuses on developing production processes for concentrated fresh milk ingredients for the international market. Ultrafiltration of whole milk solutions will be extended to maximise the product protein concentration. Electrodialysis and nanofiltration will be tailored to separate salts from lactose and produce 'designer' products with minimum wastage and energy consumption. Production of lactitol from dairy lactose, a potential new man ....Production of Concentrated Fresh Milk Products. This project focuses on developing production processes for concentrated fresh milk ingredients for the international market. Ultrafiltration of whole milk solutions will be extended to maximise the product protein concentration. Electrodialysis and nanofiltration will be tailored to separate salts from lactose and produce 'designer' products with minimum wastage and energy consumption. Production of lactitol from dairy lactose, a potential new manufacturing operation for Australia, will be assessed. This project will result in diversion of quality ingredients from commodity markets to products with significant added value. The Korumburra region will benefit financially and socially from expansion in the local dairy industry.

Optimising Removal of Proteinaceous Foulants from Membranes. Removal of proteinacous foulants from membrane systems imposes both significant economic costs in terms of chemical usage as well as significant environmental costs in terms of water usage and production of effluents from the cleaning and rinsing waters. The outcome of this project should allow us to develop methods for the prediction and optimisation of membrane cleaning performance of relevance to major Australian industries includin ....Optimising Removal of Proteinaceous Foulants from Membranes. Removal of proteinacous foulants from membrane systems imposes both significant economic costs in terms of chemical usage as well as significant environmental costs in terms of water usage and production of effluents from the cleaning and rinsing waters. The outcome of this project should allow us to develop methods for the prediction and optimisation of membrane cleaning performance of relevance to major Australian industries including the dairy, food processing and water and waste water treatment industries.Read moreRead less
Improving Powder Properties by Using Spray Dryers to Process Amorphous Components of Solids into Crystalline Materials. Australia has a large food and dairy processing industry, capturing 13% of the world dairy export market, worth US$460 million annually. This proposal will build on Australia's strengths in dairy and food industries, particularly milk powder products. This project will enhance our competitive advantage in the production of dried foodstuffs by streamlining their production and ....Improving Powder Properties by Using Spray Dryers to Process Amorphous Components of Solids into Crystalline Materials.
