Modeling of Seed Coating in a Spouted Bed

In this work, a model based on population balance equations applied to perfect mixture domains has been employed to represent the coating of soybeans with fertilizer in a conical–cylindrical spouted bed. The results of the present model provided explicit equations for the coating mean and variance. The coating mass distribution function was validated against experimental data. The effect of operational time on the distributions was analyzed, showing that the coating uniformity can be improved by increasing the operating time.
