Calculation of degree of coverage in fluidized bed coating

In this study, a new model for the fluidized bed coating process is presented. The model allows to predict the degree of coverage of solid particles. Analytical solutions of model equations for batch apparatus and for continuous apparatus operated in the steady-state mode were obtained. An algorithm for the numerical solution of model equations for multistage apparatus was developed. To identify the parameters of the developed mathematical model and to verify its adequacy, a physical experiment was conducted on a laboratory scale installation. A comparison of calculated and experimental data was performed. Good agreement is observed between the modeling and the measurements.
