Abstract:
A hulling apparatus comprising:(A) a hulling section configured to receive, husk, and discharge paddy rice as milling-processed grains in a flow having a milling-processed grain discharge width; (B) a winnowing section disposed below the hulling section and configured to receive and winnow the milling-processed grains to select specific grains from the milling-processed grains, said winnowing section comprising a winnowing path having a winnowing width perpendicular to a winnowing direction, which width is wider than the milling-processed grain discharge width; and (C) a uniform disperser disposed between the hulling section and the winnowing section and comprising: (i) a uniform disperser trough for receiving the milling-processed grains from the hulling section and discharging the milling-processed grains uniformly to the winnowing section, said uniform disperser trough having a longitudinal axis parallel to the winnowing width and having a longitudinal length substantially the same as the winnowing width; and (ii) a uniform disperser screw axially rotatable within a lower interior of the uniform disperser trough to convey in the axial direction the milling-processed grains received from the hulling section while discharging the milling-processed grains from the uniform disperser trough to the winnowing section in a flow along the uniform disperser trough.
