Abstract
A study was carried out to evaluate the effect of accelerated drying on seeds moisture content and stabilization the extracted oil using a conduction heating rotary dryer. the drying temperatures were set at approximately(85,95,105,115,125,135, and 145oc) and the drying times were set at (3,6,9,12,15, and18 min)  and the moisture contents of canola seeds was (21%-27%-31%). The results showed that all the drying processes on the falling rat period in which the rate of evaporation tends to fall as the moisture content decreases and the drying curve decays exponentially towards the equilibrium moisture content. Rapid moisture removal from seeds was obvious in all experiments particularity at higher heating surface temperature and longer exposure time .The result also showed that both the simple and the modified exponential equation models  were satisfactorily described the drying behavior of canola seeds and predicted the change in seeds moisture contents indicated by lower values of standard error of estimate (SE) and the higher coefficient of determination(R2).Meanwhile ,high temperature conduction heating the extracted canola oil was stabilized as reeducated from the lower values of free fatty acids of the samples stored under room temperature. In general, it can be said that ,the accelerated drying and heat stabilization of canola seeds using the conduction heating rotary dryer may be considered as an effective procedure for moisture ,and oil stabilization.
