Abstract

138,771. Macrory, F. S. N. April 22, 1919. Pneumatic separating.-In a milling-aspirator for separating the loose husks of oats and similar cereals from the grain or kernels, the husks and kernels are fed into the aspirator through a chamber B and are submitted to a current of air at D, whereby most of the husks and some of the lighter kernels are driven up a passage E, while the heavier kernels fall through a passage F at the bottom of which they are submitted to a further current of air drawn upwards through the conduit G to remove the remainder of the husks. Means are also provided for separating the lighter kernels from the husks and discharging them from the aspirator with the heavier kernels. Any kernels drawn up the passage E with the husks fall against a deflector board J and pass down the conduit G to join the main stream of kernels passing down the passage F, while the husks are drawn over the board J against a baffle M, whence they fall to the bottom of the aspirating-chamber and are conducted by a screw conveyer W to a discharge flap 5. The amount of air drawn through the aspirator is regulated by hinged flaps O, R, Z.
