Laboratory tests of pea seeds sorting in sloping air flow were performed in the laboratory of the Institute of Agricultural Engineering and Safety of Vytautas Magnus University. Research of pea seeds sorting in the air flow have been carried out with the aim of sowing the sorted pea seeds as catch crops. The main goal of the research was to determine the possibilities of pea seeds sorting in the air flow and to justify rational sorting parameters. Investigations of pea seeds sorting in sloping air flow were performed with a pneumatic seeds separator designed and manufactured in the laboratory. Pea seed moisture and aerodynamic properties were determined and the air flow velocity dispersion in the seed sorting chamber was measured. This dispersion depended on the position of the air flow guides as well as the air flow velocity. The pea seed feed was altered from 90 to 110 kg min-1 by changing the air flow velocity and the angle of the air flow position. It was found that pea seeds are evenly distributed in the sloping flow of the sorting chamber when the position angle of the air flow guides is 45˚. The sloping air stream could separate 80% of the larger pea seeds suitable for sowing.
