Kinematical principles of cylindrical triors used for classification

The aim of this study is to increase value and efficiency of agricultural product, which is already harvested but not cleared and classified, by processing. Thus, seed classification is to separate seeds of a plant from seeds of other plants and foreign material; classifying obtained seeds to determine the most usable ones.Triors are cylindrical devices that are used for separating foreign materials that are not eliminated by sieving and classifying the crop according to their length.In current study, with practical tests theoretical approach was tried to be examined in addition to the kinematical working principles of triors. As a consequence of the study practical determinations were made using obtained parameters.Key words: Sieves, Cylindrical Triors, Kinematical Analysis
