An important step is the parameter estimation analysis.The four unknown parameters to be estimated are the particle diameters for the three proteins and also constant b to quantify the Biot number. The parameter estimation analysis is performed based on the solution of a dynamic optimization problem where the objective is to minimize the deviation between experimental data and predicted values (see Appendix A). All the model equations are considered in this problem. During the solution procedure suitable lower and upper bounds are imposed to the parameters to be estimated. Experimental data are available in the form of dry deposit masses in each
