Influence of moisture content on aerodynamic properties of agricultural products in separation of impurities process

Knowing the particularities of the vegetable plants’ seeds is of particular practical importance, because on their basis the conditioning technologies are realized and the cultivation technologies are managed both in the field and in the protected spaces. Seed quality is a relative notion due to the fact that the seeds of some species may have different destinations: food or feed consumption, sowing or industrialization. The production and quality of any agricultural crop is determined both by the factors that act from the time of sowing to the harvesting, as well as by those that directly influence the seeds before sowing. Quality seeds are the basic block of the vegetable production system. Proper processing after seed harvesting is important to maximize the yield, longevity, vigour and overall quality. Based on these considerations, the theoretical and experimental information on the influence of some factors on the aerodynamic properties of vegetable seeds will be presented. In order to highlight these influences, experiments with various seeds will be carried out on a seed conditioning module for vegetable species-MCSL made at our institute. The quality of seed separation in this module depends on the uniformity degree of the field of air velocities in the working area, the stability of this field and its extent. The seed conditioning module for vegetable species is designed to improve the technologies for organic seed production in the case of vegetable, flower, industrial plant, cereal seeds; for solving practical problems regarding the production of seeds in vegetable crops.
