Abstract

The rheological properties of apple concentrate were studied over the range 4-70°C, solid concentration 71 wt% of apple concentrate, and shear rate 9.3-74.4 s-1. Shear rate - shear stress data indicate that apple juice concentrate (71%) behaves as pseudoplastic fluid at (4, 10°C) while the concentrate exhibited Newtonian fluid at temperatures studied (30-70°C). The effect of rheological properties of apple juice concentrate on mixing parameters was investigated. An impeller mixer was connected with ammeter in order to predict the power of the mixer at different impeller to column diameter (D/T). The relation between power number, blend number, pumping number and Reynolds number were calculated at different D/T ratio.
