The knowledge of the physical properties of agricultural products play a relevant role in the study of industrial harvesting and postharvest processes, aiming at better equipment sizing and storage conditions. Thus, the present work aims to evaluate the effects of drying and different cultivars on the physical properties of split bean beans. Four treatments were evaluated, in which samples of fresh grain produced in the state of Paraíba and Pernambuco were submitted to the drying process for 30 h at 45 ° C and 62% relative humidity. The treatments were evaluated for the parameters water content, water activity, individual grain mass, actual and apparent specific mass, dynamic angle of repose and grain dimensions (a, b, c). porosity and grain volume. It was observed that the drying process influences the physical properties of the material, providing an increase of apparent and actual specific masses. The values of water activity, individual mass, volume, porosity, dynamic resting angle and mutually perpendicular grain dimensions decreased after the reduction of water content. The sphericity was differently influenced between treatments due to uneven shrinkage in the characteristic dimensions during the drying process.
