The connecting rotating body n is fitted to the vertical rotating shaft 4, but the height of the vertical rotating shaft 4 is stopped at the point where the connecting rotating body n is fitted, and the inside of the connecting rotating body B is ground. It extends high inside the whitening chamber 2 to form an inner cylinder n, and the grinding roll bush is fitted onto the outer circumference of the inner cylinder n.

Inner cylinder n of the part between the connecting rotary body B and the grinding roll

The annular projection 31 is fixed to the upper end of the cone-shaped cylinder δ, and the bran removal net is attached to the upper end of the annular projection 31. Join the bottom edges of.

The grinding roll is attached between a part of the support plate protruding from the inner cylinder n and a lower support plate, and is made to be replaceable as it wears out.

The grinding roll 9 rotates at the same number of rotations as the vertical grain stirring roll 3 when the receiving boar fixed to the lower end of the vertical rotating shaft 4 is rotated by the original pulley r connected to the motor. As the grinding roll 3 is larger than the vertical grain stirring roll 3, it rotates much faster. The diameter of the grinding roll is large in order to increase the circumferential speed, so the communication chamber η
is required.

Diffusion R38 for the purpose of diffusing grain in all directions is radially attached to the upper surface of the upper support plate.

A boss device is attached to the center of the horizontal rod 3, and the lower end of a vertically movable pipe cutter is fixed to the boss device.

A collar 41, which is only free to rotate, is attached via a bearing C to the first upper end of the vertically movable pipe. A flange C that pairs with the flange 41 is provided below the flange 41 via a bearing. The collar C is fitted onto the outer periphery of the vertically movable pipe chestnut.

A supply hopper 57 is provided at the upper part of the grinding type whitening chamber 2, and a feed roller ferrule is provided at the lower end of the supply hopper 57, and the feed hopper 57 is opened at the upper part of the upper support plate.

8 is an outer case, 60 is a suction chamber, 61 is a suction vibrator, 6
2 is a discharge gutter.

In addition, a sample extraction hole is installed in the cone-shaped tube. 8
4 is a switching valve, and δ is a take-out gutter. When the switching valve is rotated to the temporary line state, the grains that have been initially milled in the grinding type whitening chamber z can be taken out to the takeout gutter 5, so that the milling status in the grinding type whitening chamber 2 can be known at any time. Then, from the sample, energize the rA node motor 47 to move the collar up and down, adjust the neutral force of the hene 45, and adjust the resistance of the second resistance control valve (9) to 1m! Have sex.

(effect) Next, I will explain the effect.

The supply hopper 57 is filled with brown rice as a raw material.

The adjusting motor 47 is energized to rotate the rotary shaft block, move the collar 43 up and down, and move the collar 41 downward via the spring 45. The knee resistance adjustment valve blade is moved up and down to close the gap between the second resistance adjustment valve I and the annular protrusion 31, and disconnect the grinding type whitening chamber 2 and the communication chamber η.

In addition, the adjustment motor 5 is energized to rotate the rotating contour of the tsuba 5.
1 is moved up and down to move the collar 49 up and down via a spring clasp, and the first resistor rAWJ fixed to the lower end of the vertically movable lever is
The valve 15 is moved down one moment to close the gap between the first resistance control valve 15 and the annular projection 10, thereby closing the friction type whitening chamber 1.

Next, when the motor I is energized, the original pulley r and the receiving boolean rotate with vertical rotation M4, and the vertical grain stirring roll 3, the downward feeding grain feeding spiral 7, the connecting rotary body n, and the grinding roll rotate together. Start. Therefore, when a motor (not shown) attached to the feed roller blade is rotated, brown rice is gradually fed to the upper surface of the grinding roll due to the rotation of the feed roller blade. Since a diffusion layer 1E38 is provided on the surface of the grinding roll 9, it is diffused in all directions and supplied into the grinding type whitening chamber 2 between the grinding roll 5 and the rice bran removal screen.

In the grinding-type whitening chamber 2, a grinding roll 9 rotates (7), and since the diameter of this grinding roll is large, it rotates at a high circumferential speed and performs grinding.However, as mentioned above, the grinding-type whitening chamber 2 Since it is closed, it does not fall immediately, and the appropriate amount of i- is stored and initially refined.Subsequently, when the feeding roller 8 rotates and supplies the subsequent brown rice into the grinding type whitening chamber 2, the second resistor , rA node joint structure [descends against the spring arrangement of the double spring 45, and the second resistor 1f!Ij valve (9) and the annular protrusion 31
The gap is opened and the material is allowed to flow down little by little into the communication chamber η, and from then on, the material that has been metabolically supplied and subjected to initial grinding flows down into the communication chamber η.

There is a communication rotary body n in the communication chamber η, and a downward feeding spiral 24 is formed on the outer peripheral surface of the communication rotary body B, so that the initially milled brown rice is sent in the direction F within the communication chamber η. It flows into the intermediate grain feeding chamber 6.

The grains that have flowed into the intermediate grain feeding chamber 6 are transferred to the downward feeding shell feeding spiral 7.
The grains are sent downward and supplied into the friction-type milling chamber 1, but since the discharge port 9 at the bottom of the friction-type milling chamber 1 is similarly closed, the grains are gradually stored and passed through the vertical milling stirring rolls under strong pressure. Friction is applied by the protrusions 5 of 3.

As a result, the first resistance adjusting valve 15 is finally lowered against the spring force of the spring clasp and is taken out from the take-out port, since it is further supplied from above by the rotation of the downward-feeding shell spiral 7.

In the above-mentioned rice polishing process, if the rice polishing chamber is an independent structure consisting only of a friction type whitening chamber or only a grinding type whitening chamber, a regulating resistance valve is installed in each discharge section, so that the degree of rice polishing can be adjusted freely. However, in the case of the present invention where the grinding type whitening chamber 2 and the friction type whitening chamber 1 are in communication, there is no resistance control valve at the outlet of the grinding type whitening chamber 2. Since it was not provided, it was not possible to adjust the rice polishing ratio in the grinding type whitening room 2.

17, the present invention includes a second resistance WR1i valve (9) and an annular protrusion 31 in the discharge part of the grinding type whitening chamber 2, and a first resistance control valve 15 and an annular bottom plate 10 in the discharge part of the friction type whitening chamber 1. In addition, a sample take-out head is formed in the three communication chambers η, and a switching valve is provided in the sample take-out head. Therefore, the adjustment motor 47 is driven while checking the initial grinding accuracy in the grinding type whitening chamber 2 at the sample take-out head. and adjust.
