The shaft was fitted with a rice bran fan for discharging. By attaching the rice bran fan to the machine in this way, a large installation area is not required, and the operation of the rice bran fan is simplified and inexpensive.

Further, the fan shaft is extended to both sides of the blast fan, one side of which is provided with an elongating shaft portion and the other side of which is supplied with bran-removing wind into the milling chamber. When the bran removal fan is mounted on each shaft, the bran removal fan is located on the opposite side of the bran removal fan, and the entire configuration of the machine is compacted.

Is formed, and the scraps are guided to the suction sorting air path (8) by the drifting plates (9) and (9), and the dust sucked by the draft fan (2) is discharged by the dust discharge tube (10). Emitted outside the machine.

[0007] Further, (C) is a horizontal rice blast friction type rice mill for polishing brown rice containing a small amount of rice hulls from which rice husks have been removed by the air selection operation in the air selection unit (B). Roll (1
1) is surrounded by a bran-removing screen (12) to form a grain-milling room (3), and a grain-feeding room (13) is connected to the supply of the grain-milling room (3) so that brown rice can be removed. A white rice discharge gutter (14) is provided in the feed and discharge channel, and the outer periphery of the bran removing screen (12) is a funnel-shaped draining chamber (15) at the bottom.
In the grain-feeding room (13), the rice selected in the wind-selecting section (B) by the brown rice funnel (16) is received by the brown rice funnel (16).
3). (17) indicates a shutter of the brown rice funnel (16).

[0008] The components thus constructed are integrally formed by disposing a crushing part (A) above the wind selection part (B) and a rice milling part (C) below the wind selection part (B). This constitutes a rice milling machine, and the rice milling machine is mounted on the frame base (18).

The fan shaft (1) on which the blast fan (2) is axially extended is extended on both sides, and one side of the fan shaft (1a) is formed on the extension shaft portion (1a) of the rice mill (C) to produce crushed grains. From the bran removal screen (12) constituting the chamber (3), the bran removal chamber (1)
5) An axial flow bran exhaust fan (4) for discharging the bran leaking into the wind by the wind is attached to the shaft, and the bran is removed from the brazing chamber (3) to the extension shaft (1b) of the other side. A crossflow type bran removing fan (5) for supplying wind is mounted on the shaft.

The bottom of the bran discharge chamber (15) is viewed through a bran discharge pipe (19).
The end of the fan is connected to the suction port (21a) of the fan case (21) of the rice bran fan (4) by a connecting pipe (20), and the discharge of the fan case (21) is transferred to the dust pipe (22). ) Is connected to the cyclone (23), and the bran removing fan (5) connects the blown air into the milling roll (11) and from the milling roll (11) to the milling room (3). ) Is blown out as a bran breeze.

(M) is a drive motor for transmitting rotational power in a predetermined direction to each part at a predetermined speed via a wrapped drive belt (24), and is driven by rotation of a fan shaft (1). The blast fan (2), the drainage fan (4) and the bran removal fan (5) rotate together, and blow off the suction sorting wind into the suction sorting air passage (8) to make the inside of the milling roll (11). And the bran discharge pipe (1) from the bran discharge chamber (15).
The bran falling into 9) is sucked and sent to the cyclone (23).

The bran discharge pipe (19) has a wind control plate (27) which is movable up and down with a shaft (26) as a fulcrum. )
