In order to investigate the static pressure loss of the maize deep-bed drying related to the ratio of air flux to grain mass, the experiments based on the theory of thermal engineering and deep-bed drying were engaged in. These experiments conducted on the ventilation test stand indicate the relationship between static pressure loss, depth of the bed, ventilative dimensions and the ratio of air flux to grain mass. The investigation results that during the drying, the static pressure loss increases related to the increased ratio of air flux to grain mass with the constant bed depth. The good linear relationship between the static pressure loss and ventilative dimensions was indicated. With the control of the constant ventilative dimensions, the static pressure loss increases related to the decreased ratio of air flux to grain mass and it will dramatically increased when the ratio of air flux to grain mass is small enough. To reduce the static pressure loss, enlarging the ventilative dimensions, reducing the thickness of the drying layer and reducing the speed of the wind will be the proper methods.
