Abstract:
Calcium carbonate is one of the most important minerals with multiple applications in very diverse food, pharmaceutical, chemical, plastic, paper and est. that generated by press, mangle, deposition and classification. In the simulation process mentioned in this article, a mathematical model provided to obtain dryer yield information. According to different methods of preparation and purification of this material, Spray Dryers are at the end of process as dry goods market or required properties. For this reason, first Kinetic of the material drying obtained through the experiment and the momentum equations of suspended particles in air, particle path differential equations in three dimensions, Reynolds number, heat and mass transfer coefficients and then calculate the mass and energy balance for presenting a mathematical model has combined, for discover accuracy of model, the results compared with practical experiments. A concurrent Spray dryer used in laboratory and a computer programming language (MATLAB) presented for compare the results of its execution with experimental results that show the accuracy of offered software.
