Description

  The present invention relates to a coin milling machine that makes it possible to color-sort polished white rice.

  A technique (for example, refer to Patent Document 1) is known in which white rice polished by a rice milling apparatus is supplied to a color sorting apparatus and subjected to color sorting.

Japanese Patent Laying-Open No. 2005-211751 (first page, FIG. 1).

  In a coin rice mill, since the frequency of color selection is low, it is desirable to perform the rice milling process quickly and efficiently when only the rice milling action is performed without performing the color selection.

  The invention described in claim 1 includes a rice milling apparatus 2 for milling brown rice supplied from a supply hopper 1, a color sorting apparatus 3 for color-sorting white rice polished by the rice milling apparatus 2, and rice milling by the rice milling apparatus 2. A white rice tank 4 that receives the white rice that has been screened, or white rice that has been screened by the color sorter 3, and a white rice transport path 5 that switches the white rice that has been polished by the rice milling device 2 to the white rice tank 4 and the color sorter 3. The white rice transfer path 5 is provided with a switching valve 7 which can be switched by operating the selector switch 6, and by switching the switching valve 7, the polished white rice is directly taken out to the white rice tank 4 or the color sorting device 3 is installed. It is set as the structure of the coin rice mill characterized by switching so that it can take out to the white rice tank 4 via. When brown rice is supplied to the supply hopper 1 and the changeover switch 6 is operated to the milling position, the brown rice of the supply hopper 1 is conveyed and supplied to the rice milling apparatus 2 and is polished to a predetermined milling degree to the milled rice conveyance path 5. It is sent out and guided to the white rice tank 4 by the switching valve 7. When the changeover switch 6 is operated to the color selection position, the white rice sent from the rice milling device 2 to the white rice transfer path 5 is conveyed and guided to the color selection device 3 by the changeover valve 7, and this color selection device 3. The selected white rice subjected to the color selection is taken out to the white rice tank 4.

  According to the second aspect of the present invention, the supply hopper 1, the rice milling device 2, the color sorting device 3, and the white rice tank 4 are provided adjacent to an interior rice milling building 8 and a sorting building 9 is provided in the sorting building 9. A color sorting device 3 is provided, and a white rice supply and transfer device 10 is provided between the rice milling device 2 in the rice milling building 8 and the color sorting device 3 in the sorting building 9, and the white rice tank 4 and the color sorting device 3 It is characterized in that a white rice take-out conveying device 11 is provided between them. When only the rice milling operation is performed as described above, the white rice milled by the rice milling device 2 by operating the switching valve 7 is directly conveyed from the white rice conveyance path 5 to the white rice tank 4 in the rice milling building 8 and stored therein. When the white rice immediately after milling is subjected to color sorting processing, the switching valve 7 supplies the milled rice to the color sorting device 3 in the adjacent sorting building 9 through the white rice feeding and conveying device 10 of the white rice conveying path 5. Then, color selection processing is performed. The white rice subjected to color selection is conveyed and accommodated in the white rice tank 4 in the milled rice building 8 via the white rice extraction and conveyance device 11.

  The invention described in claim 3 is characterized in that the white rice tank 4 is provided near the inner side of the side wall 12 adjacent to the sorting building 9 in the milled rice building 8. As described above, the white rice taken out from the rice milling apparatus 2 in the rice milling building 8 is conveyed and accommodated in the white rice tank 4 in the rice milling building 8 by the switching of the switching valve 7 of the white rice conveying path 5 or is sorted. After passing through the color sorting device 3 in the building 9, it is conveyed and accommodated in the white rice tank 4 in the rice milling building 8. In transporting and storing the white rice in each of the white rice tanks 4, the white rice tank 4 is provided in the vicinity of the side wall 12 located on the adjacent side of the sorting building 9 in the rice polishing building 8. Alternatively, the distance between the color sorting device 3 and the like is shortened, and the transport distance of the white rice supply and transport device 10 and the white rice take-out and transport device 11 between these buildings 8 and 9 is shortened.

  According to the first aspect of the present invention, since the white rice taken out from the rice milling apparatus 2 is taken out directly into the white rice tank 4 by switching the switching valve 7 by the changeover switch 6, it is quick and highly efficient without damaging the white rice. In addition, when this white rice is selected, the white rice taken out from the rice milling apparatus 2 is passed through the white rice conveyance path 5 guided by the switching of the switching valve 7 to the color sorting apparatus 3. While being supplied and sorted, it can be taken out into the white rice tank 4 as finely selected white rice free from the mixing of different-colored white rice, can be sorted with high accuracy, and needs a polished rice and polished rice sorting process by a simple switching operation. It is possible to select according to the efficiency of the process.

  The invention according to claim 2 requires the color sorting device 3 because the sorting building 9 in which the color sorting device 3 is installed is configured in a separate building form from the rice milling device 8 in which the rice milling device 2 and the white rice tank 4 are arranged. If the color sorting device 3 is not required as an additional form that can be installed in accordance with the above, the simple, small, and inexpensive structure can be achieved as a simple rice milling building 8 structure that excludes the sorting building 9. Even when the sorting device 3 is installed, the sorting device 3 can be configured at low cost by simple additional and retrofitting processing of providing the white rice supply / conveyance device 10, the white rice extraction / conveyance device 11, and the like.

  The invention according to claim 3 makes the arrangement position between the rice milling device 2 and the white rice tank 4 in the rice milling building 8 and the color sorting device 3 in the sorting building 9 closer to the side wall 12 side of the rice milling building 8. In particular, the mutual spacing can be shortened to shorten the white rice supply / conveyance device 10, the white rice extraction / conveyance device 11, and the like that are configured between the polished rice building 8 and the sorting building 9, thereby reducing damage to the white rice. Therefore, the configuration can be made compact and inexpensive.
