[Detailed description of the device]

[0001]

This invention relates to a circulating rice mill.

[0002]

2. Description of the Related Art A conventional circulation type rice milling machine is provided with an air-selecting device between a drop port of a circulation tank and a polishing chamber, and a debraking wire net of the polishing chamber is communicated with the collecting bran chamber. And the outlet of the wind selecting device are connected to the suction blower by hoses, and the blower is connected to the cyclone.

[0003]

In the conventional example, as shown in FIG. 5, since the wind selecting device 100 is located right above the polishing chamber 101, the outlet of the wind selecting device 100 is connected to the suction blower. In this case, an inclined duct 104 is provided at the outlet 103 of the wind selecting device 100, and a hose 105 communicating with the suction blower is fitted to the tip of the duct 104.

As a result, the distance D from the center of the milling chamber 101 to the outlet 103 of the wind selecting device 100 becomes long, and the height of the rice polishing machine itself becomes high, and therefore the height of the inlet of the circulation tank becomes high. . However, when the brown rice was stuck,
Since the heavy brown rice bag must be lifted above the circulation tank, such a high height of the inlet of the circulation tank makes it extremely difficult for a person with weak strength to carry out the sticking work. Further, in the conventional example, since the temperature of the grain rises when passing through the milling room, the taste of the milled rice is lost in the milled rice.

In view of the above circumstances, the present invention aims to reduce the height of the rice polishing machine and prevent the polished rice from losing its taste.

[0006]

According to the present invention, a wind-selecting device is provided between a drop opening of a circulation tank and a polishing chamber, and the bran removal net of the polishing chamber is communicated with the collecting bran chamber. The above-mentioned object is achieved by a circulation type rice milling machine characterized in that the outer periphery is surrounded by a communication passage through which air flows, and the outlet of the wind-screening device and the bran collecting chamber are connected via a communication passage that surrounds the milling chamber. Is what you are trying to do.

[0007]

[Function] Brown rice falling from the drop port of the circulation tank toward the milling room is subjected to selective wind selection in the middle of the process, and rice bran, rice bran, sawdust, etc. mixed in the brown rice are removed from the brown rice. To be separated. The separated rice husks and the like are collected together with the selected wind from the outlet of the wind separator through the communication passage into the rice bran chamber and sent to the cyclone. At this time, the whitening chamber is exposed to the selected wind and forcedly cooled. Further, the rice bran falling from the bran removal net of the polishing chamber is also collected in the bran collecting chamber and sent to the cyclone.

[0008]

Embodiments of the present invention will be described with reference to the accompanying drawings. A wind separator 4 is provided between the drop port 2 of the circulation tank 1 and the whitening chamber 3. The polishing chamber 3 has a cylindrical cross section, and the lower half thereof is formed by a bran-removing wire net 5. The wind separation device 5 includes a grain falling plate 6 and an inclined plate 7 facing each other, a wind selection chamber 10 provided below the both plates 6 and 7, and the both plates 6 through the wind selection chamber 10. The partition plate 11 is inclined in the direction opposite to 7, and the outlet 13 is connected to the upper end of the communication passage 12.

The communication passage 12 is formed by a cylindrical body surrounding the polishing chamber 3. The inner surface of the air separation device 5 is entirely or partially coated with a fluororesin to prevent adhesion of bran or the like, but the air separation device 5 itself may be formed of a fluororesin.

A bran collecting chamber 15 is provided below the bran removing mesh 5 in the polishing chamber 3. The upper end of the rice bran chamber 15 is connected to the outlet of the communication passage 12, and the lower end thereof is connected to a suction blower 17 via a suction duct 16.
The outlet of the suction blower 17 is connected via a discharge duct 18 to a cyclone (not shown).

Next, the operation of this embodiment will be described.
An operator (not shown) lifts the bag containing brown rice to above the circulation tank and puts the brown rice A into the circulation tank 1, and then starts the main motor 20. Then, when the shutter of the circulation tank 1 is opened, the brown rice A drops from the drop opening 2 toward the outlet of the whitening chamber 3, but is washed by the air B flowing in the wind selecting device 4 in the middle thereof.

Therefore, C such as rice bran, chaff, and sawdust mixed in the brown rice A is separated from the brown rice A. Then, those C ride on the air B, and exit from the outlet 13 to the communication passage 1
2 is sucked into the bran chamber 3 and passes through the whitening chamber 3
Collected in. At this time, the polishing chamber 3 is exposed to the air B and is forcibly cooled, so that the temperature rise of the polishing chamber 3 is prevented.

The brown rice A in the polishing chamber 3 is the polishing roll 2
While moving forward while being rotated by 1, the rice bran D generated in the whitening chamber 3 falls from the bran removal mesh 5 into the bran collecting chamber 15. And rice bran C and D are suction ducts 16,
It is pressure-fed to the cyclone through the suction blower 17 and the exhaust duct 18.

The brown rice A discharged from the milling chamber 3 rises in the vertical circulation path 28 while reaching the circulation tank 1 while receiving the resistance of the resistance device 24. After that, the brown rice A is repeatedly circulated in the same manner as described above, and when the predetermined whiteness is reached,
It is taken out of the machine through the discharge port 25. In addition, the wind separation device 4
Since the inner surface of the is coated with fluorine resin, rice bran, etc. will not adhere to the inner surface.

[0015]

As described above, according to the present invention, since the outlet of the wind-screening device and the rice bran chamber are connected to each other through the communication passage that surrounds the white-cleaning chamber, the space between the white-cleaning chamber and the outlet of the wind-screening device is Can be considerably shorter than before. That is, in the present invention, as shown in FIG. 4, the whitening chamber 3 and the outlet 13 of the wind selecting device 4 are directly connected, and the distance from the center of the whitening chamber 3 to the outlet 13 is d. In the conventional example shown in FIG. 5, from the whitening chamber 101 to the outlet 103 of the wind selecting device 100, the whitening chamber 1
The diameter D is 01, and the distance D from the center of the polishing chamber 101 to the outlet 103 is considerably larger than the distance d. Therefore, the height of the rice polishing machine of the present invention is considerably lower than that of the conventional example, so that the work of sticking brown rice becomes easy.

The polishing chamber is forcibly cooled by the air passing through the communication passage. Therefore, it is possible to prevent the temperature of the grains in the milling chamber from rising, so that unlike the conventional example, the flavor of milled rice does not deteriorate.
