Abstract: Convective solar drying of okra was carried out for three different types of cuts. Using the variation of the reduced water content or the moisture content of okra as a function of time, we were able to determine the diffusion coefficient of okra. And the mass transfer coefficient. The diffusion coefficient of okra varies from 𝟔. 𝟏𝟔 × 𝟏𝟎−𝟏𝟎 to 𝟒𝟕. 𝟖 × 𝟏𝟎−𝟏𝟎 𝒎𝟐𝒔 −𝟏 depending on the shape of the cut. By applying the Arrhenius relation dependent on the temperature of the drying air, the energy of activation of the okra obtained varies from 20.497 to 39.864 kJ.mol-1.
