In modeling of thermal processing of biological materials with rapid evaporation, it is critical to provide boundary conditions consistent with the phenomena happening at the surface to accurately predict spatial temperature and moisture content for quality and safety assurance. Boundary conditions in a mathematical model are as important as governing equations itself and describe how the heat and mass transfer takes place at the boundary. The developed model is solved in COMSOL Multiphysics 3.4 (Chemical Engineering Module)
