Description

[Detailed description of the invention] The present invention relates to a bran removal device for a grain milling machine.

Conventionally, in a mortar-type circulation grain milling machine with a vertical shaft milling trochanter, especially in a mortar-type friction-type circulation grain miller, rice grains flow down from the center of the mortar and rise around the periphery using a circulation circuit. As a general rule, the grain is milled by the frictional force generated when the rice is dispersed around the mill.
When a milling chamber is formed between the mill and the porous wall provided at the bottom of the mortar, the grain density within the milling chamber is extremely high.
The suction force generated by using the electric motor installed in the grain milling machine to rotate the blower wheel has the disadvantage that the bran removal and polishing action is incomplete and beautiful polished rice without adhering bran powder cannot be obtained.

In view of the above-mentioned points, the present invention interposes a wall plate between a rice bran box and an upper lid, and fixes the rice bran in a removable manner, and mounts an electric motor on the upper surface of the upper lid. A rotary impeller is mounted on the main shaft of the electric motor protruding inside the lid body to form a ventilation chamber, and a ventilation hole equipped with a bran removal filter is provided in the field wall plate to remove waste from the grain milling machine. By providing a suction pipe that absorbs bran air into the rice bran box in a continuous manner on the surrounding wall of the rice bran box or the upper wall lid, the bran removal suction force in the rice milling machine's rice bran removing chamber is greatly increased, and the rice milling room is improved. A high-performance bran removal device that produces beautiful polished rice with a simple structure that completes the bran removal polishing action, separates the bran powder from the bran-containing air generated by the polishing action, and discharges purified air. We aim to develop and provide this service.

The present invention will be explained with reference to embodiment figures. A porous wall 2 for removing bran is provided at the bottom of the mortar-shaped container 1, and a vertical shaft 3 is rotatably erected in the center of the porous wall 2.
A milling trochanter 4 is mounted on the vertical shaft 3, and a bran removal chamber 6 is formed by mounting a blade wheel 5 which also serves as a bran scraper below the shaft 3, and a transport trochanter is mounted above the milling trochanter 4. 7 is attached to the shaft, and the gap between the bottom of the milling trochanter 4 and the porous wall portion 2 for removing bran is integrally formed as a milling chamber 8. 10 is a rice discharge port provided on the lower side of the container 1; 11 is an exhaust port of the bran removal chamber 6; 12 is a rotation mechanism for the vertical shaft 3; is an electric motor that rotates the rotation mechanism 12.

Next, in the rice bran removing device of the present invention, a rice bran box 14 and an upper lid 15 are interposed with a wall plate 16 and are integrally fixed in a detachable manner, and an electric motor 17 is mounted on the upper surface of the lid 15.
At the same time, a rotary impeller 19 was mounted on a motor main shaft 18 protruding inside the lid 15 to form an exhaust chamber 20, and a bran removal filter 21 was mounted on the field wall plate 16. A vent portion 22 is provided, and an intake pipe 23A for absorbing the bran-containing air from the grain milling machine A into the bran box 14 is provided in communication with the peripheral wall 24A of the bran box 14, and 25 is the vent portion. 22 is a porous wall plate fitted, 26 is a locking fitting for attaching and detaching the lid 15 to and from the rice bran box 14, and 27 is an exhaust port of the exhaust chamber 20. Therefore, the rice grains placed in the mortar-shaped container 1 are sent by the transport trochanter 7 to the lower milling trochanter 4, where they are milled while being stirred in the milling chamber 8 and distributed around the circumference. At the same time, it flows upstream along the inner circumferential wall of the container 1 and descends from the center by the transport trochanter 7 to be pumped. This cyclic milling process is repeated several times to mill the rice to a predetermined degree of polishing, and the milled rice is taken out from the rice discharge port 10 at the bottom of the container 1. The rice bran powder generated by this whitening action is removed by a rotary wheel 5 provided in the rice bran removal chamber 6 which also serves as a bran scraper, and a rotating blade provided in the exhaust chamber 20 of the rice bran removal device B connected to the rice bran removal chamber 6. Due to the combined suction force with the impeller 19, the bran-containing air is sucked into the bran removal chamber 6 through the bran removal porous wall part 2, and this bran-containing air is passed through the intake pipe 23.
It is absorbed into the rice bran box 14 through A. Therefore, the bran removal effect of the rice grains in the polishing chamber 8 is doubled, and the abrasive action of the rice grains is promoted to produce beautiful polished rice without adhering bran powder. In addition, the bran-containing air collected in the bran box 14 separates the bran powder by the bran removal filter 21 and accumulates at the bottom of the bran box 14, and the purified air is transferred to the filter 21 and the vent section 22.
The air is then discharged to the outside of the machine via the rotary impeller 19 in the exhaust chamber 20. Moreover, the rice bran removal device B is detachably fixed integrally with the rice bran box 14 and the upper lid 15 with a wall plate 16 interposed therebetween, so that the rice bran powder inside the rice bran box 14 can be taken out. is simple, and each machine part 14, 1
5 and 16 can be easily and easily disassembled and cleaned, and a highly efficient bran removal action can be ensured at all times.

Claim 2 (see Figure 2)
The intake pipe 23B provided in the upper lid 15 is removably protruded into the rice bran box 14 through the insertion hole 28 provided in the field wall plate 16.
With the rice bran box 14 connected to the grain mill, the rice bran box 14 can be removed and the rice bran inside can be easily discharged.

Claim 3 provides that the intake pipe 2
The suction ports 29 of the suction pipes 23A and 23B are removably connected to the exhaust port 11 provided on the wall of the bran removing chamber 6 of the grain milling machine, so that the suction ports 29 of the suction pipes 23A and 23B
By pulling out 9, the grain milling machine A and the bran removing device B can be easily separated, and transportation, disassembly, assembly, etc. can be carried out easily.

Claim 4 provides that the lid body 15
Since the power terminal 30 of the electric motor 17 provided in the grain milling machine is removably connected to the power plug 31 provided in the grain milling machine, electrical connection of the bran removing device B is easy.
It can also be connected to a single power supply. In addition, as shown in FIG. 4, the power supply terminal 30 of the electric motor 17 and the intake pipes 23A, 23B are integrally formed, and the exhaust port 29 provided on the wall side of the rice bran removal chamber 6 of the grain milling machine and the power supply terminal 30 are integrally formed. By inserting it into the plug 31 at the same time, it is possible to simplify the connection and disconnection of the bran removal device B to the grain milling machine A, and to perform the bran removal action immediately. The bran box 14 may also be used with a bran powder outlet provided on its peripheral wall.

As described above, the bran removal device of the grain milling machine of the present invention can greatly increase the bran removal suction force in the bran removal chamber of the grain milling machine to complete the bran removal and polishing action in the milling chamber, and can also improve the polishing action. In addition to separating the bran powder from the bran-containing wind generated, the system also discharges purified air to improve the working environment.
Furthermore, the structure of the device is simple, and it is easy to assemble, disassemble, and clean, thereby improving the efficiency of removing bran and reliably producing beautiful polished rice without adhering bran.
