Moisture diffusivities of sunflower seed components

A diffusion‐based drying model has been used to separately model the thin‐layer drying of sunflower kernel and whole seed. the diffusivity of kernel was determined by means of the analytical solution of Fick's second law. the drying of whole seed was simulated by means of the numerical solution...
