PROBLEM TO BE SOLVED: To improve a hulling rate in an impeller type hulling device.SOLUTION: A hulling device comprises: a hull feed section 7 which discharges hulls introduced from an exterior to a radial direction outer side; and an impeller section 6 which is provided along an outer periphery of the full feed section 7, and is so rotated as to guide the hulls discharged from the hull feed section 7 to a radial direction outer side. The impeller section 6 comprises plural vane bodies 14 which are radially extended to a radial direction outer side, and plural inner hulling parts 21 which are located at a radial direction outer side position of each of the plural vane bodies 14, receive the hulls and perform hulling by collision with the hulls. Further, the device comprises an outer hulling part 9 which is so provided as to surround an outer periphery of the impeller section 6, receives the hulls thrown by the impeller section 6 and performs hulling by collision with the hulls.SELECTED DRAWING: Figure 8 |
