Abstract

The prospects of milk protein concentration with membrane methods are reviewed. Advantages of ultrafiltration at protein separation in comparison with standard processes are designated. A membrane apparatus with a removing of the diffusion layer is proposed. The influence of design and operation parameters on the efficiency of ultrafiltrational concentration of skimmed milk is studied. A regression analysis of the design and operation parameters influence on the concentration of solids in removed diffusion layer has been carried out. The rational values of design and operation parameters providing the efficiency of membrane concentration process of skimmed milk in the ultrafiltration apparatus with a removing of the diffusion layer have been defined.

Keywords

Membrane apparatus, diffusion layer, concentration, milk protein, design parameters, regime parameters, regression analysis
