Agricultural entrepreneurship has been boosted by land concentration, organization of farms, and the establishment of new small centers for admission, processing, and storage. At the same time former large organizations failed, which diverted the process of handling agricultural products. The trend of small dry kilns and storage facilities from 1 to 5 t/h is growing. New customers, who do not have proper knowledge and criteria when choosing proper equipment, are usually offered dry kilns of foreign production. Trade representatives who sell dry kilns also lack the necessary specialist knowledge as it is the case with their customers. The research project considered STABIL 3000 dry kilns produced by “Seting“, Delnice and used for seed drying. The dry-kilns used natural gas and fuel oil. We determined incombustible carbohydrons as well as the presence of harmful substances belonging to polycyclic aromatic carbohydrons (PAHs) on the seeds after the drying process. For this purpose we used a device known as employed the EPA 550.1 and EPA 625 method.
