Spray Drying Research

Spray dryers are critical items of processing equipment for producing common consumer products such as milk powder, detergents and paints. Poor performance is costly and dangerous in terms of thermal damage, consequent product wastage, and fire and explosion hazards. A common feature of all the research projects is the simulation of flow patterns inside spray dryers using the Computational Fluid Dynamics package CFX11, together with flow visualisation and other experimental techniques. Important sponsors of this work include the Australian Research Council, the Dairy Research and Development Corporation, Bonlac Foods Ltd, the New Zealand Foundation for Research, Science and Technology, Vic Cherikoff Food Ingredients P/L and Lang Technologies P/L.
