The purpose of this article is to determine the relevance of the research topic and the importance of increasing the yield of sunflower for Ukraine. To develop a technique for studying the effect of sunflower seed moisture on the separation quality of a pneumogravitational separator developed in previous studies. The method is given, it allows to determine the rational speed of air flow inside the aspiration channel of the developed separator. The results of the study are presented, which showed that the developed pneumogravitational separator is capable of distributing sunflower seeds with a moisture content of up to 15%. The results showed that there is no significant improvement in seed separation. Use of the developed separator as an additional drying of sunflower seeds is impossible.
