Method of cleaning sugar beet seeds from wild radish on electromagnetic seed cleaning machines by moistening the source material

Abstract

The paper considers the issues related to the influence of moisture of the source material on the quality of cleaning sugar beet seeds from wild radish depending on the supply of magnetic powder in the electromagnetic seed cleaning machine. The technological scheme of operation of the electromagnetic seed cleaning machine is resulted, the results of experiments on purification of sugar beet seeds from wild radish depending are given:

1) from the degree of humidification of the source material with mixing with magnetic powder by hand when applying the magnetic powder 6%;

2) from the supply of magnetic powder moistened by 2% of the source material with mixing with magnetic powder by hand.

The results of experiments show that when moistening the source material by 2% the requirements of the state standard for sugar beet seeds met the yields (II + III) when applying magnetic powder 6% with the position of the receiver valves on sections 2,5 and 5 with sugar beet seed yield 82, 6 - 91.2%; when applying magnetic powder 9% with the position of the dampers of the receiver on the divisions of 2,5; 5 and 7.5 with sugar beet seed yield 82.0 - 98%; when the supply of magnetic powder 12% with the position of the valves of the receiver on sections 2.5 and 5 with the yield of sugar beet seeds 93,6 – 95,5%.

Moisturizing the source material can reduce the content of wild radish in one kilogram of sugar beet to 13 - 32 pcs. with the yield of sugar beet seeds in yields (II + III) 82.6 - 91.2%.
