In order to validate the model of reference, a corn drying experimental study was conducted, and numerical simulation was carried out under the same environmental condition. The experiment and simulation results indicated that the pore network model could explain the drying process of corn material well. There was a significant difference between the temperature of corn and of pore air, hence it was unreasonable to confuse the two kinds of temperature. The pore coordination number had a great effect on the drying process. The greater the pore coordination number was, the faster the material was dried. When the pore coordination number was small, a wet cluster phenomenon appeared in the drying bin.
