Ensuring for production the necessary quantities of biological material of valuable varieties and hybrids to maintain their initial characteristics requires permanent application of measures to be carried out on a scientific basis, depending on the biological particularities of the variety or hybrid, in a predetermined system, called “production of seeds and propagating material”. Obtaining satisfactory results in the production of seed and planting material, organic certified, depends not only to a large extent on the functional quality of the equipment and the seed conditioning installations, but also on the quality of the personnel involved in the production process. Compared to other vegetable crops, vegetable seeds are produced in small quantities (except beans, peas, lentil, etc.) and their characteristics (length, width, thickness, etc.) are various. Therefore, the vegetable seed conditioning requires complex technologies and installations to ensure high quality sowing material. The paper presents some theoretical aspects regarding seed mixture conditioning, which led to the elaboration of an innovative technology for the production of organic seeds for the vegetable species and to a new type of seed conditioning module MCSL made at INMA Bucharest. The conditioning module, consisting mainly of an aerodynamic sorting machine, a sort evacuation system and a work platform, is intended for vegetable species and performs seed cleaning of light impurities by removing them in two fractions and sorting the product in three fractions. These operations can be performed by one or more passages of the useful fractions through the machine, depending on the pre-cleaning degree and the destination of the seeds. At the end of the paper the advantages of using this new type of vegetable seed conditioning module are presented.
