Drying Modeling and Simulation
A mathematical modeling of the thin-layer drying of jujubes in a convective dryer was established under controlled temperature and velocity conditions The data from the experimental drying of jujubes were used to fit ten different thin-layer models Then the drying rate constants and the coefficients of the models tested were determined via nonlinear regression analysis using a statistical

Scale
Mathematical modelling is a very powerful tool to support the scale-up of spray drying processes Process simulation has been used in chemical and oil industries since the early of 1960s and more recently pharmaceutical development scientists have also begun to make use of it during development scale-up and manufacturing (2) The use of process simulation should result in more robust
