FIELD: technology for post-gathering seed treatment by fractionation.
SUBSTANCE: claimed method includes two steps. In the first step corn boodle is separated to obtain waste, feedstuff and seed fractions. In the second one fractions are treated to obtain desired seed conditions. Before the second step corn boodle is classified on the base of laboratory seed fertility. On the base of obtained results optimal parameters for pneumatic and inertia fractionation as well as for shaker fractionation are determined In the second step pneumatic and inertia fractionation is carried out to isolate remaining part of biologically defective corn. Then shaker fractionation is carried out to isolate fraction with the first grade of laboratory seed fertility from residual corn boodle.
EFFECT: simplified treatment technology; increased yield of the first grade seeds.
