DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a rice bran removing apparatus for an automatic rice mill according to the present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 is a diagram for explaining a mounting relationship between a rice bran removing apparatus for an automatic rice milling machine according to a first embodiment of the present invention and an automatic rice milling machine, and FIG. 3 is a side view showing a state in which the apparatus is attached to an automatic rice milling machine, FIG. 3 is an exploded perspective view showing a wrinkle removal apparatus for an automatic rice milling machine according to Embodiment 1 of the present invention, and FIG. FIG. 5 is a bottom plan view showing a rice bran removing apparatus for an automatic rice milling machine, and FIG. 5 is an enlarged view of a main part showing the rice bran removing apparatus for an automatic rice milling machine of Example 1 according to the present invention.

  As shown in FIGS. 1 to 3, the rice bran removing apparatus 10 for an automatic rice milling machine 10 according to the first embodiment attaches an outer cylinder 13 to a rice milling outlet 12 of the automatic rice milling machine 11, and an inner cylinder 14 is installed in the outer cylinder 13. And a plurality of slits (openings) 18 through which the rice 16 cannot pass and only the powdered ridges 17 can pass are provided on the peripheral wall 15 (see FIG. 3) of the inner cylinder 14. A plurality of protrusions 19 are provided on the inner periphery 15a of the peripheral wall 15 of the inner cylinder 14 positioned between the slits 18 (see FIG. 5).

  Furthermore, the rice bran removing device 10 for an automatic rice milling machine is provided with an injection nozzle 21 constituting the air injection means 20 at the upstream upper edge 13a of the outer cylinder 13, and the air is injected from the injection nozzle 21 into the inner cylinder 14. Thus, by causing the rice 16 in the inner cylinder 14 to collide with the plurality of protrusions 19 with the injected air, the ridges 17 covering the surface of the rice 16 can be removed (see FIG. 5), and the peripheral wall of the outer cylinder 13 The suction port 24 of the paddle suction means 23 is provided on the outer periphery 22 of the rice cake, and the suction port 24 is opened between the outer tube 13 and the inner tube 14, and the powdered paddle 17 removed from the surface of the rice 16 is slit. 18 is configured to be able to be sucked in the direction of the soot suction means via 18.

  The automatic rice mill 11 converts the brown rice into white rice, and the rice 16 that has been polished into white rice flows out from the rice removal outlet 12. However, the rice bran 17 cannot be satisfactorily removed from the surface of the rice 16 simply by polishing the brown rice with the automatic rice milling machine 11.

  Therefore, the automatic rice milling machine 12 is provided with the automatic rice milling machine 12 for removing rice bran removing apparatus 10, thereby injecting air into the inner cylinder 14 from the injection nozzle 21 constituting the air injection means 20. The rice 16 that has flowed into the inner cylinder 14 from the rice milling outlet 12 of the automatic rice mill 11 is made to collide with the protrusion.

Therefore, even if the rice bran 17 remains on the surface of the rice 16 that has flowed into the inner cylinder 14 from the rice milling outlet 12 of the automatic rice milling machine 11, the rice 16 is caused to collide with the protrusions 19, so that the rice bran 17 is removed from the surface of the rice 16.

As shown in FIGS. 3 to 4, the outer cylinder 13 is a hollow cylinder having a rectangular cross section, and is a member in which the upstream end edge 13 b is tapered. The outer cylinder 13 is attached to the milled rice outlet 12 in an inclined manner in a state where the upstream end edge 13b is in contact with the lower edge 12a of the milled rice outlet 12 of the automatic rice milling machine 11.
In this state, the rice milling outlet 12 of the automatic rice milling machine 11 faces the substantially center of the inner cylinder 14, and the rice 16 polished from the rice milling outlet 12 flows into the inner cylinder 14.

The inner cylinder 14 is a hollow cylinder having an octagonal cross section as shown in FIGS. When the inner cylinder 14 is formed, a plurality of slits 18 are formed on one flat plate, and a plurality of protrusions 19 are press-molded so as to protrude to the inner periphery 15a. It forms in a square hollow cylinder (refer FIG. 5).
Thus, when forming one flat plate into a hollow cylinder having an octagonal cross section, the first protrusion 31 is formed and the second protrusion 32 is formed at both ends of the single flat plate.

As shown in FIG. 3, the inner cylinder 14 has an upper end portion 14 a fixed to the outer cylinder 13 by an upper mounting plate 33, and a lower end portion 14 b fixed to the outer cylinder 13 by a lower mounting plate 34.
Openings 33 a and 34 a into which the inner cylinder 14 is fitted are formed in the upper and lower mounting plates 33 and 34. Therefore, when the inner cylinder 14 is attached to the outer cylinder 13, the upper and lower end portions 14a and 14b of the inner cylinder 14 are kept open.

The slit 18 shown in FIG. 5 has a slit width W so that the rice 16 does not pass through, and is inclined at an angle θ with respect to the axis 35 of the inner cylinder 14.
By inclining the slit 18 with respect to the axis 35 of the inner cylinder 14 in the air injection direction (arrow direction), the straw 17 removed from the surface of the rice 16 is efficiently passed and discharged.

  As described above, by efficiently discharging the ridges 17, it is possible to cause the rice 16 to collide with the projections 19 without leaving the ridges 17 around the projections 19 in the inner cylinder 14.

The protrusion 19 is formed in a triangular pyramid as shown in FIG. By forming the projection 19 into a triangular pyramid, the rice 16 is caused to collide with the corners of the triangular pyramid constituting the projection 19.
By colliding with the corners of the triangular pyramid, a relatively large force can be effectively applied to the surface of the rice 16.

A shielding plate 37 is attached to the lower attachment plate 34.
As shown in FIG. 4, the shielding plate 37 is a member that covers the upper 2/3 portion 39 of the opening of the lower end portion 14 b of the inner cylinder 14, leaving the lower 1/3 portion 38. A plurality of small holes 41 are formed in a portion facing the upper 2/3 portion 39 (see FIG. 3). The small hole 41 is sized so that the rice 16 does not pass therethrough.

  In this way, the lower 2/3 portion 38 of the opening of the lower end portion 14b of the inner cylinder 14 is left, and the upper 2/3 portion 39 is covered with the shielding plate 37, whereby the injection nozzle 21 (FIG. 1 to 3), when air is injected into the inner cylinder 14, the rice 16 is prevented from scattering and flowing out from the opening of the lower end portion 14 b of the inner cylinder 14.

Further, by forming the small holes 41 in the shielding plate 37, when the suction means 23 (see FIGS. 1 to 3) is operated, the outside air can be sucked into the inner cylinder 14 from the plurality of small holes 41. It becomes possible.
Thereby, as shown in FIG. 5, the ridge 17 can be efficiently sucked from the slit 18 as shown by the arrow.

The air injection means 20 in FIGS. 1 to 3 is provided with a pair of injection nozzles 21 facing the substantially center of the inner cylinder 14 on the inner side of the upstream upper edge 13 a of the outer cylinder 13. A supply pump 43 communicates with a compression pump (not shown).
According to the air injection means 20, by operating the compression pump, the air injected from the pair of injection nozzles 21 is coaxial with the inner cylinder 14 as shown in FIGS. Inject toward the center.

Here, the rice 16 polished by the rice milling machine 11 has a heat of, for example, room temperature plus approximately 15 ° C., but in order not to impair the taste of the rice 16, the rice 16 is not heated. It is preferable to do so.
Therefore, the air injection unit 20 is configured to inject cooled air from the injection nozzle 21. By injecting the cooled air from the injection nozzle 21, the heat can be removed from the rice 16 having heat.

As shown in FIG. 1 to FIG. 3, the scissor suction means 23 is provided with a suction port 24 on the lower surface of the outer periphery 22 of the peripheral wall of the outer cylinder 13, and this suction port 24 passes through a suction hose (not shown). It communicates with a suction pump (not shown).
According to the scissor suction means 23, by operating the suction pump, the scissors 17 in the inner cylinder 14 are sucked from the suction port 24 via the slit 18, as shown in FIG.
