Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a rice husk and bran collecting device in a rice mill, particularly in a circulating rice mill.

Conventional technology and its problems Conventionally, rice removing machines have been known that process everything from paddy to polished rice with one machine, and most of them are equipped with both removing equipment and rice milling equipment. It is known to supply paddy to a circulation-type rice mill for brown rice without installing a rice mill, and to mill the rice while circulating the rice inside the machine. The former has an independent structure in which the dehulling equipment and rice milling equipment are separated, making it relatively easy to separate and collect rice husks and bran, whereas the latter has the advantage of simplifying the structure, making it more compact, and making the machine cheaper. While there are advantages, when the rice is pounded and polished, it is difficult to separate and collect the rice husks and bran that are discharged and they mix together, resulting in disadvantages such as the inability to effectively use the bran as an additive for pickles at home, for example.

To deal with this drawback, when milling rice, the rice husk is first discharged and then the bran is discharged.
Once the rice husks have peeled off and become brown rice, the rice milling machine is temporarily stopped, the rice husk bag that collected the rice husks discharged from the start of operation to the pause is removed, another bag for rice bran is attached, and operation is resumed. Circulating rice mills are already known that have been devised so that they can restart and collect the rice bran that will be discharged afterward to separate and collect the rice husks and bran. This method had the disadvantage that it required the machine to be stopped, required manual labor, and could not consistently process the process from paddy to polished rice.

The present invention solves the above-mentioned problems and provides a rice husk/bran collection device for a circulating rice mill that can consistently perform the milling process from paddy to polished rice and separate and collect the rice husks and bran. The purpose is to

Means and Effects for Solving the Problems The present invention provides a circulating rice mill that performs rice polishing and hulling, and during rice milling, a container for collecting rice bran is removably installed in the rice bran removal chamber of the rice mill, and the rice grains are removed from the rice. When milling rice,
The container for collecting rice husks is arranged in the preceding stage of the container for collecting rice bran.

As a result, during the rice milling process, the rice husks are peeled off and the rice husks that are initially discharged are collected in a rice husk collection container, and the bran that is discharged after becoming brown rice is passed through the rice husk collection container and sent to the next stage. The rice husks and the rice bran are separated and collected in a rice bran collection container placed in the rice bran.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 and 2.

, and a vertical shaft 3 erected in the center of the perforated wall panel 2
A spiral rotor 5 equipped with a polished rotor 4 is mounted on the shaft, and the vertical shaft 3 is connected to a rotating device 7 provided on a base 6 for rotation. A circulating rice mill 11 in which a bran scraping impeller 8 is mounted on a shaft to form a bran removal chamber 9, and a milling chamber 10 is formed between the bottom of the polishing trochanter 4 and the bran removal porous wall plate 2. It is. 12 is a fixed outer cylinder provided on the outer periphery of the porous wall panel 2; 13 is a rice draining gutter provided on the fixed outer cylinder 12; 14
is a rice discharge valve that opens and closes a rice discharge port provided in the porous wall panel 2;
15 is a bearing portion that supports the vertical shaft 3.

Rice husk and bran collection device 16 of the circulating rice mill of the present invention
consists of a rice husk collection container 17 and a rice bran collection container 18, and the rice husk collection container 17 has a ventilation pipe 19 that removably connects the rice bran removal chamber 9 and the rice bran collection container 18, respectively. 20 is provided on the upper part, and a resistance plate 21 is suspended from the upper part of the inner wall of the container 17 so that its angle can be adjusted. Reference numeral 22 denotes a chaff removal section provided at the lower part of the container 17, and reference numeral 23 denotes a power supply line which is provided in the ventilation pipe and becomes energized when connected.

The rice bran collection container 18 is formed by attaching a lid 25 to the top of a rice bran removal box frame 24 so as to be able to open and close freely. A bran removing filter 27 is removably attached thereto, and the lower part of the filter 27 is used as a bran collecting chamber 28.
Further, an air exhaust fan 29 is provided at the inner bottom of the box frame 24, and a partition wall 30 is provided on the top of the exhaust fan 29 to isolate it from the bran collecting chamber 28 above, and an air supply port 31 is provided on the side wall of the bran collecting chamber 28. The bran-containing wind flowing in from the exhaust chamber 26 flows through the filter 27 to the exhaust chamber 26, and the wind from the exhaust chamber 26 passes through the flow path 32 to the exhaust fan 29.
Form to collect. 33 is the rice bran room 28
The air supply port 30 and the rice husk collection container 17 are indirectly connected to the
Alternatively, a ventilation pipe directly connects to the rice polishing machine's bran removal chamber 9; 34 is a power supply line that supplies power to the electric motor 35 of the exhaust fan 29 installed in the ventilation pipe; 36 is an exhaust pipe provided on the lower side of the box frame 24; It is the mouth.

Next, to describe the operation of the above embodiment, the paddy put into the rice grain tank 1 is sent to the lower milling trochanter 4 section by the spiral trochanter 5, and the paddy is pounded while being stirred in the milling chamber 10. The rice grains are swung out to the circumferential side and flow upstream along the inner circumferential wall of the rice grain tank 1, and then descend from the center of the upper layer of rice grains by the spiral rotor 5 and circulate. In the process of this cyclical movement, paddy pounding progresses,
The rice husks are pulverized, and then the sugar on the surface of the brown rice is removed and the rice is polished. Polished rice that has been polished to a predetermined level of polishing is taken out of the machine from a rice discharge gutter 13 located at the bottom of the tank.

First, the rice husks are peeled off and discharged, and the rice husks are pulverized and fall through the holes in the porous wall plate 2 for removing rice bran. The rice husks flow into the rice husk collection container 17 through the water. In the collection container 17, the cross-sectional area of the flow path is suddenly expanded compared to that of the ventilation pipe, so the flow velocity decreases, and the flow path is bent by the resistance plate 21, so there is no airflow in the airflow. The included rice husks are deposited on the bottom of the collection container 17.

When the rice husks are exfoliated to become brown rice, the rice husks reach the limit of the defined husk collection capacity and the cross-sectional area of the flow channel becomes smaller, increasing the flow rate in the container. Adjustment of the rice husk container to be collected in the rice husk collection container 17 is as follows:
This can be done by adjusting the angle of the resistance plate 21 provided on the upper part of the inner wall to accommodate the amount of paddy input.

Next, the bran discharged during the process of turning brown rice into polished rice and flowing into the bran collection container 18 is separated from air by the bran removal filter 27 and accumulated at the bottom of the bran collection chamber 28. The purified air flows into the exhaust chamber 26 and passes through the flow path 32 to the exhaust fan 29.
The air is discharged from the exhaust port 36 to the outside of the machine.

When it is not necessary to separate and collect rice husks and bran, or when only rice milling is performed, remove the rice husk collecting container 17 from the rice husk/bran collecting device 16 and insert the rice bran collecting container 18 directly into the rice milling machine. Of course, all you have to do is contact Nukamuro 9.

In addition to this embodiment, the exhaust fan 29 may be installed inside the bran removal chamber 9 or in any flow path between the bran removal chamber 9 and the collection container.

Effects of the invention As described above, the rice husk and bran collection device of the present invention has improved the ability to consistently separate and collect rice husks and bran in conventional circulation-type rice milling machines, which have had difficulty in consistently separating and collecting rice husks and bran during paddy milling. This machine can separate and collect the rice husks and bran in a conventional rice milling operation, making effective use of the rice bran, and has the functions of a circulating rice milling machine that has the advantages of a simple structure, small size, and low cost. It is something that improves.
