[0009]

According to the present invention, the first and second units 35 and 29
It is a multi-story rice mill, but the first 35 and the second 29
Since the inside of the case 1 has the same structure, when producing in a factory, a large number of units in which the grain feeding spiral 9 protrudes from the upper lid 10 of the case 1 are manufactured, and when the first unit 35 is used, the downward feed is performed. The periphery of the helix 9 is surrounded by a husking cylinder 13,
Is fixed to the upper surface of the upper lid 10 of the case 1 with screws 15, and a rotary cylinder 17 is mounted on the outer periphery of the grain feeding cylinder 13 via a bearing 16.
A grinding type milling roll 19 is fitted around the upper end of the rotary cylinder 17, and the outer circumference of the grinding type milling roll 19 is surrounded by a bran removing tube 20. Entrance 22
Forming a forced supply cylinder 23 outside the inflow port 22;
The bran removing cylinder 20 and the forced supply cylinder 23 are attached to an outer frame 26 provided on the outer periphery of the rotary cylinder 17, and the outer frame 26 is fixed to the upper lid 10 with screws 27 to become the first machine 35.

The second machine 29 is a second machine 29 when a hopper 28 is mounted around the downward feeding and feeding spiral 9 and is mounted with the screw 15.

[0013] When the combination as described above is arranged as shown in FIG. 3, the operation is as follows. When brown rice is supplied to the stuffing hopper 31, the stuffing elevator 30 rises and the supply tank 32
And gradually flows into the forced supply cylinder 23, is sent downward by the downward feed spiral blade 24, flows into the ascending grinding and milling chamber 21 through the inflow port 22, and flows through the ascending grinding and milling chamber 21. The rice is initially milled while rising, and is passed through the channel 25 to the grain transfer cylinder 1
3 and is sent downward by the downward feed-feeding spiral 9 and is subjected to middle-stage rice milling in the falling-type friction milling chamber 12. The middle-milled rice is discharged from the discharge gutter 34, flows through the inclined gutter 37, rises the elevator 36, flows through the inclined gutter 38, flows into the hopper 28, and is finished by the second machine 29. In addition,
Since the head brown rice is not sufficiently polished, the switching valve 42 is switched back to the original position, and after a certain time, the switching valve 42 is switched to take out the finished rice discharge gutter 44.

[0012]

According to the present invention, a flow-down type friction milling chamber 12 is provided inside.
And a case 1 in which a downward feeding and feeding spiral 9 is projected above the upper lid 10, and ascending grinding which is connected in series with the friction milling chamber 12 by screws 15 and 27 on the upper lid 10 of the case 1. A first machine 35 formed by attaching the milling chamber 21, a second machine 29 of only the friction milling chamber 12 formed by attaching a hopper 28 with the screw 15 on the upper lid 10 of the case 1, 1st machine 3
5. A lifting machine 30 for rolling brown rice into the grinding and milling chamber 21

In addition, since the grinding and milling chamber of the first machine 35 is the ascending grinding and milling chamber 21, the initial milling can be performed without unevenness because the grinding and milling chamber has resistance to the rise of the grain as compared with the case where the grinding and milling chamber is of the downflow type. Not only that, a grinding chamber having a small volume due to strong grinding action can be provided, and the entire apparatus can be downsized. Further, since the position of the inflow port 22 of the ascending grinding and milling chamber 21 of the first machine 35 is low, the height of the uplifting machine 30 can be reduced. In addition, since the second machine 29 is the falling-type friction rice milling room 12, the flow of the grains is good, so that a beautiful finish can be obtained. Also,
A switching valve 42 is provided at the upper end of the finishing machine 40 of the second machine 29, and a return gutter 43 for returning to the steeping machine 30 is provided.
