Experimental investigation of the acoustic-convective drying of unhusked Korean rice

Experiments on determination of the kinetic curves of drying of unhusked Korean rice have been conducted on two (small-and large-scale) acoustic-convective dryers of capillary-porous materials of the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences. Different regimes of drying were used. The characteristic time of drying to a prescribed final humidity has been determined; the absence of the influence of the scale factor on the kinetics of drying of rice has been shown. The coefficient of moisture conductivity of rice has been evaluated.
