The article presents the modernization of the design of the universal seed mordant PSS-20 by installing an axial fan and air ducts for closed air circulation in the processing chamber, which will ensure the full use of the mordant, work safety and increase the productivity of cultivated crops. The main advantage of this design is that the seeds in the same plane as the suspension flow is affected by the air flow, which improves the penetration into the layer. Air ducts make it possible to reuse the suspension that has not settled on the seeds. This is achieved due to the closed lid design. During operation, the fan creates excessive pressure inside the seed stream and rarefaction outside, and so small drops of solution that have penetrated the seed stream are sucked in by the fan and re-fed into the stream.
