Description

[Detailed explanation of the invention] Among various rice polishing machines, this invention mainly relates to a circulation type rice polishing machine.The purpose of this invention is to remove the types of impurities such as rice husks and rice bran during husking and milling from brown rice. A new circulation-type rice milling machine with excellent functions that can switch the suction passage in two ways to adjust the suction power depending on the situation, quickly sort out and remove these impurities, and perform milling work quickly and accurately. The objective is to provide this at a low cost with a simple structure.

Conventionally, when milling brown rice or paddy using a circulating rice mill, there is not much of a problem when it comes to brown rice.
When the rice grains are pounded, if the impurities mixed in the rice grains, such as lint and stems, are larger than the mesh of the rice bran removal net, they will not be removed from the rice bran removal net during milling, and the rice grains will become completely polished. However, it often remains during rice milling,
The result is that the polished rice is taken out in a very poor state. In addition, when attempting to completely remove these impurities from the rice bran removal net, there was a problem in that the rice milling process took too long and a large amount of broken rice was produced, significantly reducing the efficiency of the rice milling process. .

The present invention was devised to solve the above-mentioned problems, and its structure and operation will be explained in detail below with reference to the drawings of the embodiment. grain roll 4,
The structure of the main operating parts of the rice milling machine, such as the bran removal net 5, the milling chamber 6, the resistor 7, the input pulley 8, the suction fan 9, and the suction duct 10, is basically the same as that of the conventional circulating rice mill. When the grains stored inside are brown rice, the brown rice is fed into the grain feeding chamber 3 from the grain drop port 2a at the bottom of the hopper 2, and the brown rice is fed by the grain feeding roll 4 provided penetrating the chamber. The rice bran produced during milling is polished by the pressure of the resistor 7 while being pushed to the front milling chamber 6, and then returned to the inside of the hopper 2, which gradually improves the polishing degree. 9, the rice is discharged through the bran removal net 5 to the cyclone 11 outside the machine.

In the above-mentioned circulation type rice milling machine, the present invention provides a path leading from the grain dropping port 2a of the hopper 2 to the grain feeding chamber 3.
R ₁ is provided with an appropriate number (two in the figure) of grain sink plates 12a, 1 that are inclined diagonally downward from above.
2b, and this part is formed into the rice husk sorting section _P1 , and a suction bran remover is connected from the passage R1 of the chaff sorting section _P1 and the grain feeding room ₃ to the suction fan 9 via the suction duct 10. A suction pipe 13 bypassing the grain feeding chamber 3 is connected to the passage R ₂ of the section P ₂ , and a passage R ₃ of the chaff suction section P ₃ is provided in this section _.
The meeting part 1 between the passage R ₂ of P3 and the passage R ₃ of the paddy suction part P ₃
The present invention is characterized by the provision of a damper 15 that selectively opens and closes passages R ₂ and R ₃ at or before passages R 2 and R 3 .

In addition, in the drawing, the meeting area 1 of passage R ₂ and passage R ₃ is
Although an embodiment in which a damper 15 is provided only in the rice husk suction portion P ₃ is shown, the damper 15 may include a separate damper (not shown) in addition to the meeting portion 14, for example, in the suction port 13a of the rice husk suction portion P3. Yes, and if there are paths R ₂ and R ₃ before the meeting section 14, the paths R ₂ and
One damper may be installed in each R ₃ .

Since _the circulating rice milling machine according to the present invention has the above structure, when milling brown rice, there _are
Switch the damper 15 provided in the meeting part 14 from the horizontal position to the vertical position, open the passage R ₂ of the suction bran removing part P ₂ and close the passage R ₃ of the rice husk suction part P ₃ , as described above. Rice can be milled using the same route as conventional rice milling machines. However, like when paddy was being plucked,
If the grain contains foreign matter such as lint, ramus, and rice husk that cannot pass through the mesh of the rice bran removing net 5, the damper 15 is reversely switched from the vertical position to the horizontal position, and the passage of the suction rice bran removing part _P2 is Close R ₂ and passage of rice husk suction part P ₃
If R ₃ is opened and the machine is driven, the grains are supplied from the grain drop opening 2a of the hopper 2 to the grain feeding chamber 3 via the passage R ₁ of the chaff sorting section P ₁ in the case of this embodiment.
First, it falls onto the upper sink plate 12a, flows diagonally downward along the upper sink plate 12a, and then
After falling onto the lower sink plate 12b and further flowing down along the lower sink plate 12b, it is supplied to the lower grain feeding chamber 3, but at that time, the falling layer of grains flows through the upper and lower sink plates 12a, While flowing down the grain 12b, it is diffused and gradually becomes thinner and more uniformly distributed, making it easier for the wind to pass through the flowing layer of the grain and flowing into the inlet 13a on the opposite side, and the grain is Contaminants such as millet and rice husks mixed in the rice husks are sorted and separated by the force of this wind, and are sucked into the passage R ₃ of the rice grain suction part P ₃ from the suction port 13a, and then from the lower suction fan 9 to the outside of the machine. Since the rice is discharged into the cyclone 11, it is possible to reliably remove impurities larger than the mesh of the rice bran net, which could not be removed by conventional rice milling machines, from the grains. Then, the damper 15 is switched to the original bran removal position and the brown rice is polished.

Here, a large amount of bran accumulated in the passage R ₂ of the suction bran removing part P ₂ from the chaff chamber 3 through the bran removing net 5 during hulling is removed by switching the damper 15 from the horizontal state to the vertical state. If this operation is carried out, since the passage R ₂ has a funnel shape through which the bran can easily flow, the bran is quickly discharged from the machine through the suction fan 9 without clogging the inside of the passage R ₂ .

In the above case, the switching operation of the damper was explained as fully open and fully closed, but in reality, the opening and closing angle of the damper is changed depending on the size and mixing ratio of foreign substances, the progress of rice milling work, etc. It is desirable to perform rice milling work efficiently under the best conditions while continuously adjusting the rice husk and rice bran.

As described above, if the present invention is applied to a circulation type rice milling machine, the conventional problems mentioned at the beginning can be successfully solved, and the types of contaminants such as rice husks and rice bran can be removed during husking and milling from brown rice. This is a new circulating rice mill that has excellent usage functions that allow you to adjust the suction power by switching the suction passage in two ways depending on the situation, quickly sort out and remove these impurities, and perform rice milling work quickly and accurately. The machine can be provided at low cost due to its simple structure.
