Thin layer drying of canola pods variety (serw-10) was investigated. In conducting the thin layer experiments, the air velocity was held constant at 2.5 m/sec, six different levels of air temperature ranging from 45 to 70 ^oC, and four different levels of air relative humidity ranging from 30 to 60% were used. The obtained results were fitted with six different examined mathematical drying models. The results showed that the Two terms drying model succeeded in describing thin layer drying curve of canola pods. A multiple regression analysis was also used to describe the interaction effect of the drying air temperature and relative humidity on the constants and coefficients of this model.
