Abstract: The invention comprises a bean cleaning apparatus comprising a plurality of pairs of elongated inclined rotating parallel rods. One of the rods in each pair has a spiral groove along its length and the other rod has a smooth cylindrical outer surface. The rods in each pair are mounted to a frame with a space between the rods in each pair narrower than a small bean and with the one rod in its rotation spiralling doward so as to auger the beans downward along the rods. The rods in their rotation in each pair rotating toward one another to move the beans toward the rods and with the engagement of the rods with the beans acting as a abresion to the outer surface of the beans to clean the beans of foreign matter as it moves along with the space allowing small particles of foreign matter to pass between the rods.
