Abstract
Simulation technique was used to determine the drying charaden'stic of roughrice in a horizontal-semi cylindrical plenum (drying-bed). The mathematical model simulation used in study was a set of partial d&rential equation. In order to ve*
the validity of the simulation technique, the experimental tests were tun to provide data to he compared with the simulation results. The experimentation was conducted using rough-rice samples at two levels of drying temperatures, 50% and
45%. The results indicate that the mathematical model predicts the charactetkiics of the actual rough-rice dtying very closely that the differences are staWicaUy no significant, although there are little bit (=95%) differem between the simulatitm
technique and the test run results. These are true not only for the drying air temperature data but also for the moisture content data as well.
