Optimization of design and operational parameters of a vertical airflow seed separator for oilseed crops

The aim of the study is to determine the optimal design and operational parameters of a vertical airflow seed separator for oilseed crops to improve separation efficiency, productivity, and energy efficiency. Numerical modeling of the separation process was performed in Simcenter Star-CCM+ using the CFD-DEM approach, which allowed the assessment of the motion of seed mixture particles, their interaction with the airflow and with each other, as well as the influence of the fractional composition on the process efficiency. Experimental verification was carried out on a vertical airflow seed separator equipped with a loading unit with a vibratory feeder, a pneumatic separation channel, an air distributor, a suction chamber, and a settling chamber. The optimal operating modes of the separator were determined, ensuring maximum sunflower kernel content in the collection zone, high productivity, and minimal energy consumption. The results of the study allow the formulation of analytical dependencies for optimizing the design and operational parameters of aerodynamic separators and can be used to improve the technological processes of preparing oilseed crops at industrial enterprises.
