Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a rotary sorting tube that has a large number of pot holes on its inner circumferential surface and rotates around a horizontal axis, and is used to sort mixed rice such as paddy and brown rice. The present invention relates to a grain sorting device.

[Prior art]

After wind-selecting the scraped rice from the husking section, it is fried while being sorted by a vertical grain sorting device, and the sized brown rice and unhulled rice are fed from above to a rotating sorting cylinder, where they are sorted and milled. JP-A-59-76551 discloses a conventional device for taking out the material from below.

[Problem that the invention seeks to solve]

In this conventional device, the 1/22 cup of paddy/brown rice after the small rice is taken out by the vertical grain sorting device is fed directly to the rotary sorting cylinder, so the small paddy rice is sorted. The mixed brown rice and grain-sized brown rice were mixed with unhulled rice and fed to the sorting cylinder once. As a result, there was a drawback that small amounts of unhulled rice were mixed into the brown rice.

Therefore, this invention separates small grains and large grains into small grains and large grains using a vertical grain sorting device, and separately supplies the classified small grains and large grains to a rotating sorting tube with a small pot hole and a rotating sorting tube with a large pot hole. This aims to improve the sorting accuracy and eliminate the drawbacks of conventional devices.

[Means to solve the problem]

The technical means of this invention for solving the above-mentioned technical problems are as follows: 1. This rice hulling machine is equipped with a rice sorting path 4 for wind-selecting grained rice, and a plurality of rotary sorting cylinders 11a and 11b, each of which has a large number of pot holes on its inner circumferential surface and rotates around a horizontal axis. A vertical grain sorting device 21 is provided which can sort the mixed rice into small grains and large grains while vertically frying the mixed rice after wind selection in the sliding rice wind sorting path 4. The small grains sorted by the vertical grain sorting device 21 are fed to one rotating sorting tube 11a which has a small pot hole, and the large grains sorted by the vertical grain sorting device 21 are fed to the other rotary sorting tube 11a which has a large pot hole. The structure of the rice hulling sorting device is characterized in that the sorting tube 11b is supplied.

[Function and effect of the invention]

The scraped rice scraped off in the shedding section 1 is wind sorted in the scraped rice wind sorting path 4 to remove the chaff, and then fried while being sorted by grain shape in the vertical grain sorting device 21 to form small grains. Sorted into large and large grains,
The small grains sorted by the vertical grain sorting device 21 are supplied to one rotary sorting tube 11a, which has a small pot hole, and is also fed to the vertical sorting tube 41'! By supplying the large grains sorted by the grain sorting device 21 to the other rotary sorting tube 11b, which has a large pot hole, large grains and small grains are sorted in separate rotary sorting tubes, and small It is possible to prevent 45 unhulled rice from becoming brown rice and to improve the accuracy of 1 sorting.
