| Abstract: | Wheat kernel drying are analysed by applying a model based on traditional diffusion equaion. The model considers diffusion of moisture through vapour and liquid phases. Two dimensional finite element method is presented in wheat drying. The drying model accurately predicted wheat drying. |
