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.
