Convective and radiant drying of a polymer aqueous solution

Abstract

The aim of this work is to minimize the drying time of a polymer aqueous solution placed into a Petri dish while respecting strict constraints. Several experiments performed in a laboratory setup have shown the interest of a drying combining convective and infrared radiation as long as irradiation is correctly controlled. In this way, a one dimensional liquid diffusion model taking into account the product shrinkage was developed. Model predictions are in good adequacy to mass and temperature experimental data.
