Abstract (en)
A grading machine for grading articles by size, eg fruit and vegetables such as apples, tomatoes and potatoes, comprising: a grading tray (1) provided with at least one elongate opening (3) which increases in width from one end to the other; resilient mountings (5) supporting the grading tray (1) in a manner which allows it to be oscillated; and one or more pneumatic pistons (6) arranged to oscillate the grading tray (1). The oscillation being such as to lift and move the grading tray (1) forward during each cycle, the angle of the forward movement with the horizontal and the amplitude and frequency of the oscillation being such as to cause articles on the grading tray (1) to move from the narrow end of the opening (3) towards the wide end until they reach a position where they are able to pass through the opening (3) whereupon they are directed by an off-take tray (9) into containers (10).
