The seed purity air blowr is a specialized instrument developed using microelectronic control technology based on the aerodynamic
behavior (floating speed) of material particles in the airflow, specifically for seed purity testing. The bottom fan will transport the wind through the mesh to the vertical air selection pipeline, separating impurities and light, flattened seeds from pure seeds. This way, the sample will be divided into two parts: the impurity (collected in the impurity cup) and the pure seed (collected in the sample cup).
