influence of kernel fluidization on the drying and cultivation properties of canola seeds

several methods are used to decrease seed drying time and enhance the quality of dried seeds. influidization methods, good aeration occurs during the drying process. in this research, conditioned seedswith 20% d.b. moisture content were dried at 30°, 40°, 50° and 60°c using three bed conditions (fixed,minimum fluidized, fluidized). all experiments were done using a batch-type fluidized bed dryer and threereplications. temperature and bed changes in the dryer on canola seed drying kinetics were investigated.the cultivating properties of dried seeds, such as final germination percentage, emergence percentage,seedling leaf area index and seedling dry mass percentage were compared with naturally dried seeds as acontrol. experimental results showed that temperature and seed bed changes had significant influences onthe canola seed drying process. suitable aeration was observed during and after minimum fluidized beddrying, which may save energy during the drying process. the fluidized seed bed decreased drying timemore than 23% over the fixed bed. the fluidized resulted in about an 8% increase in drying time over thesemi-fluidized seed bed. when the use of high temperature is limited for drying, fluidization at moderatetemperatures can a suitable alternative for drying heat-sensitive materials. drying at 30° and 40°c usingsemi-fluidized beds is a good choice for drying canola seeds. it did not have harmful effects on the canolaseed cultivation properties and kept them within standard limits.
