PNEUMATIC-MECHANICAL DEVICE FOR GRAIN PEELING

摘要

FIELD: technological processes; agriculture; machine building.;SUBSTANCE: invention relates to the grain processing industry and can be used for peeling (fruit shells removal from the grain). Pneumatic and mechanical device contains feeding hopper with the loading branch pipe, fan with upper and lower blades, working chamber, made in the form of helical cylindrical spiral of rectangular cross-section, upper and lower mesh longitudinal partitions. Fan upper blades serve to feed the grain into the working chamber and are bent towards the fan rotation to give to the fed into the working chamber grain maximum acceleration. Lower fan blades create airflow to allow the grain and peeling products movement in the working chamber and are bent in the fan rotation reverse direction to create the uniform airflow.;EFFECT: pneumo-mechanical device is characterized by increased peeling efficiency.;1 cl, 3 dwg
