  According to the brown rice supply method and apparatus of the present invention, brown rice is stored in a mobile, relatively small-capacity brown rice container, and the brown rice stored by transporting the brown rice container is directly transferred from the brown rice container to the milled rice area. I tried to supply. For this reason, the required site area for installing a large brown rice storage tank becomes unnecessary, and construction costs can be reduced. In addition, the brown rice container itself is transported instead of the brown rice conveyor, which makes it easy to manage the amount of transportation, and enables the supply of brown rice with a high degree of flexibility for small-sized rice milling needs. Can be easily accommodated.

  FIG. 1 is a schematic view showing an embodiment of a brown rice supply method and apparatus in a rice milling plant according to the present invention. In FIG. 1, brown rice 12 carried by a forklift from a brown rice warehouse (not shown) is put into a receiving hopper 10. The brown rice 12 is conveyed upward by the vertical conveyor 14, and first, the magnetized material 18 such as iron pieces in the brown rice is removed by the magnet separator 16. Subsequently, the fine impurities 22 in the brown rice are removed from the brown rice 12 by a sieving machine 20 commonly called Wanshi. Further, the brown rice 12 is removed by the stone remover 24 to remove the stones 26 in the brown rice. A movable brown rice container 30 stands by on the cradle 28 below the stone remover 24, and the brown rice 12 from which foreign substances have been removed by the various pretreatments described above is filled into the brown rice container 30. That is, the receiving hopper 10, the vertical conveyor 14, the magnet separator 16, the sieving machine 20, and the stone removing machine 24 constitute a brown rice filling area 80 of the brown rice 12 into the brown rice container 30 that also serves as a pretreatment of the brown rice.

  FIG. 2 is a cross-sectional view of the brown rice container 30. The container portion that receives the brown rice 12 has a hopper shape, and includes a cylindrical body portion 32 and a funnel portion 34 below it. A discharge port 38 having an open / close valve 36 is provided at the lower end of the funnel portion 34. Four support legs 40 are attached to the container portion, so that the brown rice container 30 can stand on its own. A cross beam 42 is stretched between the support legs 40. The capacity of the brown rice container 30 is a capacity capable of storing 1,000 kg of brown rice. Brown rice is usually received in a 500 kg cloth flexible container or 30 kg paper bag. Therefore, the brown rice container 30 can store brown rice for two bags for a cloth flexible container and 33 bags for a 30 kg paper bag.

  The brown rice container 30 filled with the brown rice is delivered to the stacker crane 44. At this time, the cross beam 42 is used to receive the load of the brown rice container 30. The stacker crane 44 loaded with the brown rice container 30 moves to the container storage rack 46. The container storage rack 46 has a large number of container lockers 48 for individually storing the brown rice containers 30.
