Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a circulating rice milling machine.

[0002]

[Prior art]

 The conventional circulation type rice milling machine is provided with an air selector between the drop port of the circulation tank and the whitening chamber, and the debris wire mesh of the whitening chamber is communicated with the rice bran chamber. The outlet of the selector is connected to a suction blower by a hose, and the blower is connected to a cyclone.

[0003]

[Problems to be solved by the device]

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

Therefore, the distance D 1 from the center of the milling chamber 101 to the outlet 103 of the wind-screening device 100 becomes long, so that the height of the rice polishing machine itself becomes high, and therefore the height of the inlet of the circulation tank becomes high. . However, since a heavy brown rice bag has to be lifted up to the top of the circulation tank when the brown rice is stuck, if the height of the inlet of the circulation tank is high, it is extremely difficult for the weak person to carry out the sticking work. Becomes Moreover, in the conventional example, the temperature of the grain rises when passing through the brewing room, so that the taste of the pearled rice deteriorates during milling.

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

[0006]

Means for Solving the Problems The present invention is to provide a wind-selecting device between a drop opening of a circulation tank and a whitening chamber so that the bran removal net of the whitening chamber can be communicated with the rice bran chamber. It is intended to achieve the above-mentioned object by connecting the outlet of the wind selecting device and the rice bran chamber through a communication passage that surrounds the.

[0007]

[Action]

 The brown rice falling from the drop port of the circulation tank toward the milling room is subjected to the wind selection by the selective wind on the way, and the chaff, rice bran, sawdust, etc. mixed in the brown rice are separated from the brown rice. . 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 selective wind and forcedly cooled. The rice bran that falls from the bran removal net in the polishing chamber is also collected in the rice bran chamber and sent to the cyclone.

[0008]

【Example】

 An embodiment of this 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 polishing 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 sorting device 5 includes a grain falling plate 6 and a swash plate 7 facing each other, a wind selection chamber 10 provided below the both plates 6 and 7, and the both plates described above via the wind selection chamber 10. It is composed of a partition plate 11 that is inclined in the direction opposite to 6 and 7, and an outlet 13 that is connected to the upper end of the communication passage 12.

The communication passage 12 is formed by a cylindrical body that surrounds the whitening chamber 3. The inner surface of the air separation device 5 is coated with fluororesin in whole or in part to prevent adhesion of bran or the like, but the air separation device 5 itself may be formed with fluororesin.

A bran collecting chamber 15 is provided below the bran removing net 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 to a cyclone (not shown) via an exhaust duct 18.

Next, the operation of this embodiment will be described. An operator (not shown) lifts the bag containing brown rice onto 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 falls from the falling port 2 toward the outlet of the polishing chamber 3, but is washed by the air B flowing through 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, these C are sucked into the communication passage 12 from the outlet 13 by riding on the air B, and are collected in the rice bran chamber 15 through the surrounding of the polishing chamber 3. 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 milling chamber 3 advances while being rotated by the milling roll 21, and the rice bran D generated in the milling chamber 3 falls from the bran removal mesh 5 into the bran collecting chamber 15. Down. Then, rice bran and the like C and D are pressure-fed to the cyclone through the suction duct 16, the suction blower 17, and the exhaust duct 18.

The brown rice A discharged from the whitening chamber 3 rises in the vertical circulation path 28 while reaching the circulation tank 1 while receiving the resistance of the resistance device 24. Thereafter, the brown rice A is repeatedly circulated in the same manner as described above, and when it reaches a predetermined whiteness, it is taken out of the machine through the discharge port 25. Since the inner surface of the wind separator 4 is coated with fluororesin, rice bran or the like will not adhere to the inner surface.

[0015]

[Effect of device]

 As described above, according to this 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 distance between the white-cleaning chamber and the outlet of the wind-screening device is considerably shorter than before. can do. 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, the polishing chamber 101 is separated from the outlet 103 of the wind selecting device 100 by the diameter of the polishing chamber 101, and the distance D from the center of the polishing chamber 101 to the outlet 103 is the distance. It is much larger than 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.

Further, the whitening 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 brewing room from rising, and unlike the conventional example, the flavor of the pearled rice does not deteriorate.
