Description

Technical Field

[0001] The utility model relates to a bran separation device and belongs to the field of grain processing equipment. Background Art

[0002] There is a layer of husk on the surface of grains. In the process of processing grains into rice, the husk must be peeled off first. The peeled husk forms bran, and then the rice (grain) and bran need to be separated, which is usually called bran separation.

[0003] like Figure 1 The traditional processing process shown in the figure requires the rice husker to grind the rice husks first to separate the rice husks from the surface of the rice husks. The rice husks enter the wind separator from the rice husker through the air lock, and the rice husks are discharged from the lower grain outlet and the rice husks are discharged from the air suction tube to separate the rice husks from the rice husks. However, the existing wind separator only has one wind screening process, and the separated rice husks will contain grains. On average, one ton of rice husks contains five kilograms of grains, resulting in food waste. If the rice husks are screened again, the cost is too high and the screening efficiency is low.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only embodiments of a part of the present invention, rather than all of the embodiments.

[0025] The utility model discloses a rice bran separation device. Figure 1 , Figure 2 As shown, including:

[0026] The separation mechanism 1 is provided with a centrifugal channel 11, and a feed inlet 12 and a bran outlet 13 are provided at both ends of the centrifugal channel 11 respectively. The centrifugal channel 11 is also provided with an air inlet 14 between the feed inlet 12 and the bran outlet 13; and at least one air supply inlet 15 is also provided between the air inlet 14 and the bran outlet 13.

[0027] Among them, the centrifugal channel 11 is a bent channel structure. The air inlet 14 also serves as a grain discharge port. After the grain and bran mixture enters from the feed port 12, it can move to the vicinity of the air inlet 14 under the action of gravity, and the wind at the air inlet 14 will screen the grain and bran mixture by wind; due to the characteristics of heavy weight and difficulty in blowing up, most of the grains will fall out from the air inlet 14 to achieve grain discharge; and the bran and a small amount of grain will change direction along the centrifugal channel 11 under the action of wind and move to the bran outlet 13. During the movement, the wind from the air supply port 15 performs secondary wind screening on the bran and a small amount of grain, so that the bran and a small amount of grain are separated, and the bran outlet 13 is located above the bran after the secondary wind screening, and the bran can be sent out from the bran outlet 13, while a small amount of grain can be retained in the centrifugal channel 11.

[0028] Under the action of wind, the embodiment of the utility model utilizes the centrifugal channel 11 to achieve the first separation of rice bran. At the same time, by setting an air supply port 15 between the feed port 12 and the bran outlet 13, the wind from the air supply port 15 is used to perform the second separation of rice bran, thereby improving the rice bran separation effect.

[0029] Optional, such as Figure 2 As shown, the centrifugal channel 11 is U-shaped, the air inlet 14 is located at the bottom of the U-shape, and the feed inlet 12 and bran outlet 13 are both located at the top of the U-shape.

[0030] Among them, Figure 2 As shown, the centrifugal channel 11 is U-shaped, with the top of the U-shaped facing upward and the bottom of the U-shaped facing downward. After the grain and bran mixture enters from the feed port 12, it can move to the vicinity of the air inlet 14 at the bottom of the U-shaped under the action of gravity. The wind at the air inlet 14 will screen the grain and bran mixture by wind. Since the grain is heavy and not easy to be blown up, most of it will fall out from the air inlet 14 to achieve grain discharge. The bran and a small amount of grain will change direction along the centrifugal channel 11 under the action of wind and move to the bran outlet 13. During the movement, the wind from the air supply port 15 performs secondary wind screening on the bran and a small amount of grain, so that the bran and a small amount of grain are separated. The bran outlet 13 is located above the bran after the secondary wind screening. The bran can be sent out from the bran outlet 13, while a small amount of grain can be retained in the U-shaped structure of the centrifugal channel 11 and move to the air inlet 14 under the action of gravity.

[0031] Optional, such as Figure 2 , 3As shown, the air supply port 15 is located at the outer side of the U-shaped structure of the centrifugal channel 11.

[0032] Among them, Figure 3 As shown, the air inlet 14 and the bran outlet 13 are combined with the U-shaped structure of the centrifugal channel 11 to form a curved air duct. The bran and a small amount of grains will move along the air duct under the action of wind, but the bran and a small amount of grains themselves have a certain inertia and will not move completely along the air duct. At this time, the bran and a small amount of grains are screened by secondary wind through the air supply port 15 located on the outer side of the U-shaped structure. Due to the characteristics of large area and light weight, the bran will be blown inward by the wind at the air supply port 15, while the grain itself has a large weight and a small amount of displacement, so that the bran and a small amount of grains are separated under the action of the secondary wind screen.

[0033] Optionally, the separation mechanism 1 is further provided with an air regulating plate 16 between the air supply port 15 and the air inlet 14. The air regulating plate 16 is rotatably arranged in the centrifugal channel 11. When the air regulating plate 16 is adjusted, the area of ​​the air inlet 14 is expanded or reduced. The structure and adjustment method of the air regulating plate 16 are prior arts. However, the air regulating plate 16 in this scheme adjusts the wind force of the air supply port 15 while realizing the wind force adjustment of the air inlet 14.

[0034] The air regulating plate 16 is further provided with a control handle 161 on the outside of the separation mechanism 1 , and the user can adjust the angle of the air regulating plate 16 through the control handle 161 , and use the air regulating plate 16 to adjust the wind force of the air supply port 15 and the air inlet 14 .

[0035] The embodiment of the utility model can adjust the wind force of the air supply port 15 and the air inlet 14 according to actual needs by setting the air regulating plate 16, so as to adapt to different grains and expand the usability of the chaff separation device.

[0036] Optionally, the separation mechanism 1 further includes a grain storage box 17 , which is located between the air supply port 15 and the bran outlet 13 , and is disposed on one side of the centrifugal channel 11 , and is communicated with the centrifugal channel 11 .

[0037] Among them, in the embodiment of the utility model, the grain storage box 17 and the centrifugal channel 11 are an integrated structure, and those skilled in the art can also set the grain storage box 17 and the centrifugal channel 11 as a detachable structure according to actual needs. The grain storage box 17 is located outside the U-shaped structure of the centrifugal channel 11, so that the grain can enter the grain storage box 17 after being centrifugally thrown out, and the bran flows out through the bran outlet 13 above.

[0038] The grain storage box 17 of the embodiment of the utility model can also be provided with a vertical partition structure, and the bran outlet 13 is located on the other side of the partition structure, and the partition structure is used to separate the bran and the grains.

[0039] Optionally, the bran separation device further comprises:

[0040] The suction cylinder 2 is connected to the bran outlet 13.

[0041] Among them, the suction tube 2 can be connected to structures such as a fan. The suction tube 2 draws out the air in the separation mechanism 1 to reduce the internal air pressure of the separation mechanism 1. Under the action of air pressure, external air enters the separation mechanism 1 from the air supply port 15 and the air inlet 14 to form wind for wind screening.

[0042] Particularly, the grain storage box 17 further includes a box body and a cover body 171. The box body is provided with a cleaning port, the cover body 171 is arranged at the cleaning port, and the cover body 171 is movably connected to the box body.

[0043] Among them, Figure 1 As shown, the cleaning port is arranged on the top of the box body. Those skilled in the art can also arrange the cleaning port on the side or other positions according to actual needs.

[0044] Rice oil bran is the outermost oil film after the rice is husked. Since the oil bran is viscous and easy to stick, the traditional rice bran separation equipment needs to be equipped with a rotary screen when used to separate rice and oil bran, but it is very easy to get clogged, and normal production cannot be achieved, and the efficiency is extremely low. The embodiment of the utility model is suitable for separating rice and oil film. By setting the box body and the cover body 171, it is convenient for the staff to clean the oil bran grains attached to the grain storage box 17. It only needs to be cleaned regularly during use, which greatly improves the separation of rice and oil bran.

[0045] Particularly, the cover 171 is hinged to the box body and / or the cover 171 is detachably connected to the box body.

[0046] Among them, the cover 171 and the box body can adopt a hinged structure to form an opening and closing effect of the grain storage box 17 by folding the cover 171. The cover 171 and the box body can also directly adopt a detachable structure to achieve a detachable connection between the cover 171 and the box body.

[0047] Optionally, the bran separation device further comprises:

[0048] The rice husker 3 has a bottom which is connected to a feed inlet 12 .

[0049] Among them, the rice husker 3 grinds the grains to separate the grains from the bran.

[0050] Optionally, the bran separation device further comprises:

[0051] The air shutoff device 4, the bottom of the rice husker 3 is connected with the feed port 12 through the air shutoff device 4.

[0052] Among them, the air shutoff device 4 is specifically a rotary feeder, which can send the grains and bran separated in the rice husker 3 into the separation mechanism 1 in batches for separation.

[0053] The utility model is suitable for separating rice bran and rice hair, etc. due to the arrangement of the air inlet, and has a wide application range; the arrangement of the grain storage box improves the separation efficiency; broken rice, residual rice and rice germs in the rice bran can be completely separated, and compared with the prior art that an average of five kilograms of grains are contained in one ton of rice bran, the utility model greatly saves food, and the separation effect is much higher than that of the prior art.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the specification of this application, the technicians can still modify or replace the specific implementation mode of the utility model with equivalents, but these modifications or changes do not deviate from the scope of protection of the pending claims of the utility model application.
