The aim of the research is the determination of rational technology of post-harvest treatment of seeds of sunflower. Existing technologies that are implemented in grain cleaning units and complexes for the preparation of seed material type GCM (Voronezhselmash), "Polyma" (Belarus) and others perform seed treatment by sequential processing on all cleaning machines. Return at any point not provided, it is necessary to conduct repeated handling throughout the chain of cars that leads to the reduction of seed yield, decreased performance and increased injury to seed. Research Institute of oil crops designed container technology in universal seed cleaning complex, eliminates these disadvantages and allows finishing the processing of seed material at the time of matching seeds with the requirements of GOST at any stage. In seed output pneumatic sorting machines MOS-9N, which is seed cleaning complex that contained diseased seeds that differ from healthy seeds by color and lowered their quality. To improve the quality of seed material was applied photoelectron separator F 5.1, followed by separation of sunflower seeds on the dimension fraction (Ø7-Ø8 mm, Ø8-Ø9мм). In the result of the research container technology with subsequent fractionation of sunflower seeds on the separator at the final stage of their processing improves the yield of highly certified seeds from 92.90 to 93.20 % compared 91,20 % (without fractionation) and reduce the content of their departure from 68,83 to 65,60 % compared 85,52 % (without fractionation) depending on size fraction
