Description

  The present invention relates to a huller using an impeller-type removal device.

  A rice milling machine is known which is configured by combining a detaching device in a form of friction detachment with a rubber roll, a brewed rice sorting device with a swinging sorter, a brown rice sorting device with a vertical rotating sorting cylinder, etc. (for example, patents) Reference 1).

JP-A-5-7843 (second page, FIG. 1).

  The present invention constitutes a small, simple and inexpensive rice huller. As in the above-mentioned patent document, the conventional hulling machine uses a multistage swing sorter, multistage gangue sorter, etc. as a roll form with a large unloading capacity, and has a large vibration, noise, and a large configuration. The installation location is likely to be limited.

The invention described in claim 1 includes an impeller-type deflation device (1) and a wind selection device (3) provided with a wind selection chamber (2) for wind-selecting the grains deflated by the detachment device (1). ), And a wind selection chamber (2) provided with a selection unit (8) that receives the grains flowing down the bottom cereal board (21) and selects the grain size while lifting the grain to extract the finished brown rice, 8) has a cereal helix (4) on the rotating outer peripheral surface and rotates around the vertical axis, and the cerealing cylinder (5) covers the outer periphery of the cerealing cylinder (5) and forms a number of sorting holes. net cylinder (6) and Bei example a Kazesenshitsu (2) and the junction of the sorting section (8), ventilating from the sorting section (8) to Kazesenshitsu (2) inlet (12) A hulling machine characterized by forming

  The grain deflated by the defluxing device is transferred to the wind selection chamber 2 and subjected to the selection wind to be wind-selected. Grains (mixed rice of straw and brown rice) that has been sucked and removed from the rice husks and dust in the wind sorting chamber 2 and received by the drifted cereal plate 21 flows into the bottom of the sorting unit 8 on the front side, and this sorting unit 8 By the rotation of the inside cereal cylinder 5, the grain is sorted by the sorting net cylinder 6 while being crushed by the crushed helix 4. Brown rice is selected after waste rice is selected during the graining process.

  Since the suction wind pressure in the wind selection chamber 2 works through the intake port 12 inside the sorting section 8, dust in the sorting section 8 is sucked into the wind sorting chamber 2 by this suction wind.

  According to the first aspect of the present invention, the finished brown rice can be taken out by the impeller-type detaching device 1, the wind sorting chamber 2, and the sorting unit 8 for sorting the particle size. It is possible to obtain a compact rice huller that can take out the finished brown rice with a small number of components without the need for a dynamic sorting device or a dedicated elevator for lifting the grain.

In addition, the air selection chamber 2 and the sorting unit 8 connected to the front side of the wind sorting chamber 2 are communicated with each other through the air inlet 12, and the inside of the sorting unit 8 is communicated with the wind sorting chamber 2. Since the suction air flows, the configuration can be simplified, and the suction dust action inside the selection unit 8 can be easily performed using the suction air pressure in the wind selection chamber 2.
