Abstract

A size grader for pod vegetables includes a horizontally oriented rotatable drum which contains banks of fixed grading members and movable panels oriented over each bank. The banks and panels are wanted on the drum so as to be parallel to its longitudinal axis. The final grading members and the movable panels have grading vanes which are disposed circumferentially to the drum and transversely to its longitudinal axis. The apertures between the fixed grading vanes and the movable vanes defines grading surfaces. A control rod mounted to the drum longitudinally across each row of panels and operatively engaged with a rowring enables movable panel to move selectively with respect to its corresponding fixed panel as the drum rotates so that the movable panel moves toward the fixed panel in grading position when the panel is in a lower level in the drum and moves away from the fixed bank in a clearing position when the panel is located above the drum.
