[Industrial applications]
TECHNICAL FIELD The present invention relates to a rice milling rice mill that integrally includes a rice removal unit, a stone removal unit, and a rice milling unit that are integrally connected to a rice removal unit that includes a removal unit and a wind selection unit. .
[0002]
[Prior art]
In the conventional rice milling apparatus, the air removal sorter, the rice selection section, the stone removal section, and the milling section are juxtaposed and combined in a plane to obtain white rice from the rice. Therefore, the installation area is large, so that it is not suitable for work in a small work place, and it is also inconvenient to transport when moving in the work place. In addition, of the grains supplied from the destoning section to the milling section, surplus grains exceeding the processing capacity of the milling section are returned to the preceding process from the overflow trough through a separate means. As a result, the structure is complicated and the weight is increased, which makes transportation more inconvenient.
[0003]
[Problems to be solved by the invention]
As described above, the conventional rice milling apparatus has the drawbacks described in the preceding section, and therefore, in the present invention, the rice selection section and the stone removal section which are connected to the air removal machine are used. And the rice milling section are arranged three-dimensionally to make the whole device compact and small in installation area, making it easy to handle, and to remove excess grains supplied from the stone removal section to the rice milling section. -It is created for the purpose of directly reducing the weight from the bar flow gutter to the horizontal grain collection gutter of the wind selection unit, eliminating a separate reduction means, and simplifying the configuration and reducing the weight.
[0004]
[Means for Solving the Problems]
In order to provide an apparatus capable of achieving the above-mentioned object, the present invention provides a device in which a wind separator is mounted on a wind separator and a wind separator is provided on the rear side of the dryer. The rice selection unit that sorts the waste, the stone removal unit that removes contaminating foreign matter, and the rice milling unit that grinds the material from which foreign matter has been removed are three-dimensionally arranged and connected to form a single unit. A discharge channel of an overflow gutter for reducing a surplus of grains supplied from a blanking unit to a rice milling unit is connected to a horizontal grain collection gutter of the wind selection unit. It is.
[0005]
[Action]
Therefore, the paddy put into the paddy funnel in the paddy section of the paddy wind separator is drained, and the scraps are filtered in the lower wind separator to remove rice husks and pity, and remove brown rice and brown rice. Foreign matter mixed with immature rice is extracted by the rice selection part and the stone removal part where the mixed rice of paddy is three-dimensionally arranged and connected continuously on the rear side of this air removal machine. Then, the extracted grains are milled by the milling unit to form white rice.
[0006]
As a result, the mixed rice of unpolished rice and paddy, which has been air-extracted by the air extraction machine, is arranged in a three-dimensional arrangement on the rear side of the air extraction machine. The unpolished rice and foreign matter are removed by the milling unit and the milling unit, and the crushed rice is milled.The whole body is elongated in the front-rear direction, but the entire equipment is compact, the installation area is small, and work in a narrow workplace Suitable for transportation and convenient for transportation. In addition, the surplus of grains supplied from the destoning section to the rice milling section is returned from the overflow trough to the horizontal grain collecting trough of the wind selection section, which eliminates the need for a separate return means, thereby simplifying the configuration. And reduce the weight.
