| Abstract: | A dynamical mathematical model is developed to describe sublimation drying, which conjugates heat and mass transfer simultaneously. The model is employed to investigate mechanism of one side heating mode and hybrid heating mode during sublimation drying. The influences of product temperature, interface temperature and water vapour flux on the process are studied. |
