Kinetics of convective drying of the sugar beet pulp

Abstract

Different authors have investigated hot air drying of sugar beet pulp, but no data on drying kinetics can be found in the literature. The aim of this study was to find suitable model for drying kinetics of sugar beet pulp. Of all models applied to drying curves, the best results were obtained for logarithmic equation. Also it was found that pressing of sugar beet pulp reduces time needed for drying by 10%, without any change in drying kinetics or any significant influence on coefficient of rehydration ratio.
