And thus, the highest values of the separation effectiveness index
were obtained in the process of air separation of crushed mixtures
of Amulet yellow lupine. Its values were varied with relation
the moisture content of the samples, the degree of diminution,
and the air flow velocity in the separator duct. The highest value,
87.2%, was obtained for a grainy mixture of a moisture content of
1
= 10.1%, at a working slot width a
= 2.5 mm and air flow velocity

= 12.8 m s

. As the moisture content of the mixture increased,
the effectiveness of air separation of the seed cover
fraction deteriorated distinctly. At a moisture content W
= 15.7%
and a working slot width a
= 4.1 mm, the value was only 33.1%.
