Conclusions
Then, D diffusion coefficient is calculated for The results have been shown that the model and the analytical method provide an accurate means of calculating the moisture distribution, moisture diffusion coefficients, and their dependence on temperature for practical purposes. For a controlled drying of pumpkin seeds, a model is also essential for the moisture diffusion, besides the kinematics model. The theory prescribed with the model explained in this study has been validated with experimental results, which revealed two different expressions for drying of pumpkin seed for natural and forced-convection cases with solar energy heated air
