Description

[Detailed description of the invention] The present invention relates to an improvement of a bran removing 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 milling is carried out by the frictional force generated when the mill is dispersed around the mill.
When a milling chamber is formed between the grain mill and the porous wall provided at the bottom of the mortar, the grain density in the milling chamber is extremely high, and an electric motor installed in the grain milling machine is used to rotate the wind exhaust impeller. With a moderate suction force, the bran removal polishing effect is incomplete and there is a drawback that beautiful polished rice without adhering bran powder cannot be obtained.

In view of the above points, the present invention provides a vertical shaft equipped with a transport trochanter equipped with a milling trochanter in the center of a porous wall plate for bran removal provided at the bottom of a mortar-shaped container. It rotates by connecting to a rotation mechanism installed on the base, and
In the grain milling machine in which a bran removing chamber is formed in the lower part of the porous wall body, the upper part is used as an exhaust chamber, the lower part is used as a bran collecting chamber, and a bran removing filter is mounted on the boundary wall of the rice milling machine. At the same time, a rotary impeller connected to an electric motor is mounted inside the base to form a ventilation chamber, and the ventilation passage of the bran removal chamber is connected to the ventilation opening of the bran collection chamber provided in the container. At the same time, by connecting the air supply path of the ventilation chamber to the exhaust port of the exhaust chamber provided in the container, the bran removal polishing action in the bran removal chamber of the rice miller is completed by strong suction force. In addition, the bran-containing air generated by the whitening action is introduced into a separate container for removing bran to separate the bran powder, and the purified air that is discharged cools down the heat generated by the drive unit in the base.
Therefore, we have developed and provided a high-performance bran removal device that has a simple structure, performs high-efficiency bran removal, makes the bran removal process simple and convenient, and can consistently mill beautiful, high-quality polished rice. That is.

The present invention will be explained with reference to embodiment figures. A porous wall plate 2 for removing bran is provided at the bottom of the mortar-shaped container 1, and a transport trochanter 5 equipped with a milling trochanter 4 is mounted on a vertical shaft 3 erected in the center of the porous wall plate 2. In addition, the vertical shaft 3
is connected to a rotation mechanism 7 provided on a base 6 for rotation, and a bran scraping impeller 8 is mounted on the lower part of the perforated wall body 2 of the vertical shaft 3 to form a bran removal chamber 9. form,
This is a circulating grain milling machine A in which the milling chamber 10 is integrally formed between the bottom of the milling trochanter 4 and the porous wall body 2 for removing bran, and 11 is the outer periphery of the porous wall body 2. 12 is a rice ejecting gutter provided on the fixed outer cylinder; 13 is a rice ejecting valve that opens and closes the rice ejecting port provided on the bottom of the porous wall panel 2; 14 is a bearing that supports the vertical shaft 3; Department.

Next, the bran removing device of the present invention is provided with a bran removing container 18 having an upper part as an exhaust chamber 15 and a lower part as a bran collecting chamber 16 and a bran removing filter 17 mounted on the boundary wall thereof. , a rotary impeller 20 connected to an electric motor 19 is mounted inside the base 6 to form an exhaust chamber 2.
1, and connects the air exhaust passage 22 of the bran removal chamber 9 to the air supply port 23 of the bran collecting chamber 16 provided in the bran removal container 18, and connects the air supply passage 24 of the ventilation chamber 21 to the Connected to the exhaust port 25 of the exhaust chamber 15 provided in the rice bran removal container 18, 26 is an opening/closing fitting for opening and closing the rice bran removal container 18, 27 is the ventilation port of the ventilation chamber 21, and 28 is the lid of the mortar-shaped container 1. Since the above-mentioned structure is adopted, the rice grains put into the mortar-shaped container 1 are transferred to the lower milling trochanter 4 by the transport trochanter 5.
It is fed into the milling chamber 10, milled while being stirred, and distributed around the circumference, and flows upstream along the inner peripheral wall of the container 1 and descends from the center by the transport trochanter 5, where it is milled. be done.

The milled rice that has been milled to a predetermined degree of polishing by going through this circulation milling process several times is taken out of the machine from the rice discharge gutter 12 at the bottom of the container 1.

The bran powder generated by this whitening action is transferred to the bran scraping impeller 8 provided in the bran removal chamber 9 and the exhaust chamber 1 of the base 6.
Due to the combined suction force with the rotary impeller 20 provided at 5, the bran-containing wind is strongly absorbed into the bran removal chamber 9 through the holes in the porous wall panel 2 for bran removal, and this bran-containing wind is also discharged. Road 22
The bran powder flows into the bran collecting chamber 16 of the bran removal container 18 through the bran removing filter 17, and the separated bran powder is accumulated at the bottom of the bran collecting chamber 16, and the purified air is The purified air flows into the exhaust chamber 15 and is passed through the air supply path 24 to the exhaust chamber 21 in the base 6.
and flows out from the exhaust port 27, and the electric motor 1
The heat generated by the drive parts 9 and the like will be cooled and discharged to the outside of the machine.

Claim 2 provides that the exhaust passage 2
2 and the air supply path 24 so that the bran removal container 18 can be detached from the machine body, the bran removal container 18 can be easily removed from the machine body and the bran inside the bran collection chamber can be removed. Powder can be easily discharged.

In this way, the rice bran removing device for a grain milling machine of the present invention is provided with a separate container for removing rice bran, the upper part of which serves as an exhaust chamber, the lower part of which serves as a rice bran collection chamber, and a rice bran removing filter is mounted on the boundary wall thereof. Since a rotary impeller connected to an electric motor is installed inside the base to form an air exhaust chamber, the air exhaust drive part of the rice bran removal container is formed inside the base to simplify the device structure. At the same time, it is possible to cool the heat generated by the air exhaust drive unit using the rotary impeller, and the weight of the rice bran removal container has been reduced, making it easier to transport and take out the rice bran powder.
The air exhaust passage of the bran removal chamber is connected to the air supply port of the bran collection chamber provided in the bran removal container, and the air supply path of the ventilation chamber is connected to the exhaust port of the exhaust chamber provided in the bran removal container. Since the scraping impeller and the rotary impeller are connected to the scraping impeller and the rotary impeller, a strong and highly efficient bran removal action is performed, which eliminates the bran removal effect performed only by the exhaust impeller mounted on the vertical shaft of the conventional device. Compared to the above, the bran removal force is doubled to completely remove the bran adhering to the rice grains, and the polishing and polishing action is activated to ensure high-quality polished rice with a glossy grain surface.
