The cleaning processing represents an important link of the process of capitalization of vegetal-origin products and, at the same time, an essential operation of the cereal seed conditioning chain. Taking into account all considerations, the experts' attention has been drawn by the study of phenomena which influence the process of separating impurities, aiming at a maximum reduction of impurities. The paper presents experimental researches of qualitative indexes of impurities separation out of cereal seed mass for equipment using combined principles of separation (according to specific mass and aerodynamic properties of seeds). The experimental equipment used for the experimental research was composed of a gravity separator and an aspiration installation with a fan. Also, the influence on the separation quality index of the following operating parameters is determined: material flow rate of the shaking separator, air flow of the aspiration installation, work surface tilting, work surface oscillation amplitude. The results obtained during the experimental researches reveal that the working process of the gravity separator is efficient and it achieves high cleaning of wheat for milling. Source
