Description

Technical Field

[0001] The utility model belongs to the technical field of rice milling machines, and in particular relates to a multi-extrusion and light-milling rice milling machine with germ-retaining function. Background Art

[0002] Rice milling is one of the main processes in rice processing. After the rice husk is removed by a rice husker, the rice becomes brown rice. The brown rice has a certain surface smoothness of the rice grains, but the germ, commonly known as rice brain or rice sprout, is still wrapped in a rice bran layer. The germ is rich in nutrients such as fat, protein, starch, vitamins and minerals, and is the essence of rice. Therefore, it is necessary to retain the germ of the brown rice. The processing flow is to add the brown rice to a rice mill, and then process the brown rice to remove the rice bran layer of the brown rice and retain the germ of the brown rice. In order to separate the germ rice and the rice bran, an air flow will be blown to the germ rice and the rice bran. The germ rice will continue to fall due to gravity, while the rice bran will be blown away by the air flow for separation. Although the existing device can separate the germ rice and the rice bran, it has certain defects. For example, in the announcement number "CN 217120350 U" discloses a multi-squeeze and light-milling germ-retaining rice milling machine. After producing germ rice, the device starts the bellows to allow broken rice and rice bran produced during rice milling to enter the bellows through the filter screen, thereby collecting the broken rice and rice bran. Although the device can collect the broken rice and rice bran, since the path length of the wind-selected broken rice and rice bran of the device is short, some of the broken rice and rice bran have not been blown away by the air flow and will be discharged from the same discharge port with some whole rice, which will waste time in the later stage of re-sorting, increase the processing steps, and reduce the processing efficiency.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 6 As shown, the utility model provides the following technical solutions:

[0028] A multi-extrusion light-milling embryo-retaining rice milling machine comprises a rice milling part and a material guide part for conveying brown rice along a preset path, wherein the rice milling part comprises a first grinding belt wheel 18 and a second grinding belt wheel 26 rotating along a horizontal axis, a milling channel for milling brown rice is formed between the first grinding belt wheel 18 and the second grinding belt wheel 26, a material discharge end of the material guide part is connected to the milling channel, and the material discharge end of the material guide part is located above the milling channel;

[0029] A blowing member and an exhaust member, a guide channel is formed between the blowing member and the exhaust member, and the guide channel is located below the first grinding belt wheel 18 and the second grinding belt wheel 26;

[0030] The guide plate 25 is arranged on the guide channel, and the guide plate 25 is inclined downward from the side close to the blowing part to the side of the exhaust part, and a through-type installation groove 23 is opened on the guide plate 25, and a gauze 24 is installed inside the installation groove 23. There is a gap between the bottom of the guide plate 25 and the exhaust part for the germ rice to pass through.

[0031] Through the above technical solution, when personnel need to process brown rice to produce germ rice, the brown rice is added to the material guide member. After the brown rice is added to the material guide member, the brown rice is guided by the material guide member to be transported between the first grinding belt wheel 18 and the second grinding belt wheel 26. When the brown rice is between the first grinding belt wheel 18 and the second grinding belt wheel 26, the first grinding belt wheel 18 and the second grinding belt wheel 26 rotate, and then the first grinding belt wheel 18 and the second grinding belt wheel 26 mill the brown rice, and then remove the rice bran of the brown rice to form germ rice. When the germ rice and the rice bran layer fall down, the germ rice and the rice bran layer are received by the guide plate 25. The rice bran is cooperated with the gauze 24 on the mounting groove 23 to prevent the rice bran and the germ rice from passing through the mounting groove 23. The blowing piece works to guide the gas flow, so that the gas is blown toward the exhaust piece, and then the gas flows between the blowing piece and the exhaust piece. When the gas blows toward the rice bran and the germ rice, due to the inclined setting of the guide plate 25, the rice bran and the germ rice move toward the side of the exhaust piece. When the germ rice and the rice bran fall from the guide plate 25, the germ rice falls due to gravity, and the rice bran moves toward the exhaust piece under the action of the airflow until it is discharged through the exhaust piece, thereby completing the separation of the rice bran and the germ rice.

[0032] Specifically, in one embodiment, regarding the material guide member:

[0033] like Figure 1-Figure 6 As shown, the material guiding member comprises a material guiding cover 2 , two material guiding plates 5 are symmetrically mounted inside the material guiding cover 2 , and a material guiding channel 17 is formed between the two material guiding plates 5 .

[0034] In this embodiment, when brown rice needs to be added, the brown rice is added to the material guide cover 2. After the brown rice is added to the material guide cover 2, the brown rice is guided by the two material guide plates 5, and then the brown rice is transported between the first grinding belt wheel 18 and the second grinding belt wheel 26, and the brown rice can be processed by the first grinding belt wheel 18 and the second grinding belt wheel 26.

[0035] In addition, in the present utility model, regarding the above-mentioned rice milling part:

[0036] like Figure 1-Figure 6 As shown, the rice milling component also includes a bottom shell 1, which is fixedly connected to the bottom of the material guide cover 2, and the bottom of the bottom shell 1 forms a rice outlet 16 for discharging germ rice, the first grinding belt wheel 18 and the second grinding belt wheel 26 are both rotatably connected to the inside of the bottom shell 1, and the first grinding belt wheel 18 and the second grinding belt wheel 26 are partially located inside the material guide cover 2.

[0037] In this embodiment, after the brown rice is added into the guide cover 2, the brown rice is guided by the two guide plates 5, and then the brown rice is transported between the first grinding belt wheel 18 and the second grinding belt wheel 26, and the brown rice is processed by the first grinding belt wheel 18 and the second grinding belt wheel 26. After the brown rice is milled into germ rice, it falls into the bottom shell 1, and the germ rice is received by the bottom shell 1, so that the germ rice falls onto the guide plate 25, and the germ rice and rice bran are received by the guide plate 25, and the gauze 24 on the mounting groove 23 cooperates to prevent the rice bran and the germ rice from passing through. The installation groove 23 works through the blowing member to guide the gas flow, so that the gas is blown toward the exhaust member, and then the gas flows between the blowing member and the exhaust member. When the gas is blown toward the rice bran and the germ rice, since the guide plate 25 is inclined, the rice bran and the germ rice move toward the exhaust member. When the germ rice and the rice bran fall from the guide plate 25, the germ rice falls due to gravity, and the rice bran moves toward the exhaust member under the action of the airflow until it is discharged through the exhaust member, and the brown rice is discharged through the rice outlet hole 16, thereby completing the separation of the rice bran and the germ rice.

[0038] And, regarding how the first grinding belt wheel 18 and the second grinding belt wheel 26 rotate, as shown in FIG. Figure 1-Figure 5 As shown, the bottom shell 1 is fixedly connected with the first motor 8 and the second motor 10 , and the output ends of the first motor 8 and the second motor 10 are connected with the first grinding belt wheel 18 and the second grinding belt wheel 26 respectively.

[0040] In order to improve the rice milling efficiency, the rotation speeds of the first grinding belt wheel 18 and the second grinding belt wheel 26 are different, and the rotation speed of the first grinding belt wheel 18 is greater than or less than the rotation speed of the second grinding belt wheel 26 .

[0041] And, in the utility model, in order to facilitate the discharge of rice bran, as Figure 1-Figure 6 As shown, a side plate 4 is fixedly connected to one side of the material guide cover 2, and a first air inlet cavity 3 is formed on the side of the side plate 4 facing away from the material guide cover 2. A plurality of exhaust pipes 6 are horizontally fixedly connected to the other side, and the air outlet ends of the exhaust pipes 6 extend to the interior of the material guide cover 2. A first air inlet fan 7 is installed inside the first air inlet cavity 3.

[0042] In this embodiment, when the device processes brown rice to produce rice bran, in order to prevent the rice bran from overflowing from above the material guide hood 2, the first air intake fan 7 on the side panel 4 is operated to guide the gas to flow into the first air intake chamber 3, and the gas is guided by the side panel 4 to be transported to the inside of the material guide hood 2 through the exhaust pipe 6, thereby forming a shield for the gas to prevent the rice bran from leaking from above the material guide hood 2.

[0043] In addition, in the present invention, regarding the above-mentioned exhaust member:

[0044] like Figure 1-Figure 6 As shown, the exhaust component includes a discharge pipe 9, a through discharge hole 20 is opened on one side of the bottom shell 1 close to the discharge pipe 9, the discharge pipe 9 is fixed on the bottom shell 1, and the discharge pipe 9 is connected to the discharge hole 20, and a baffle 21 is fixedly connected to the inside of the discharge hole 20.

[0045] In this embodiment, when the rice bran and the germ rice slide from the guide plate 25, the blowing member works to guide the air flow to blow toward the rice bran and the germ rice, so that the rice bran is discharged through the discharge hole 20, and the rice bran is guided through the discharge pipe 9 and finally discharged through the discharge hole 20.

[0046] In order to improve the efficiency of rice bran discharge, Figure 6 As shown, a third motor 19 is fixedly connected inside the bottom shell 1 , a scraper 22 is connected to the output end of the third motor 19 , and the third motor 19 is located above the baffle 21 .

[0047] In this embodiment, when the rice bran is discharged through the baffle 21, the scraper 22 is driven to rotate by the third motor 19, so that the scraper 22 continuously scrapes the baffle 21, so that the rice bran can be continuously discharged through the baffle 21, thereby improving the rice bran discharge efficiency.

[0048] In addition, in the present invention, regarding the above-mentioned blowing member:

[0049] like Figure 1-Figure 6As shown, the blowing member includes an air guide pipe 14, a second air inlet cavity 11 is opened on the side of the bottom shell 1 facing the air guide pipe 14, the air guide pipe 14 is fixedly connected to the bottom shell 1, and the air guide pipe 14 is communicated with the second air inlet cavity 11, an air guide cavity 13 is opened inside the air guide pipe 14, and a second air intake fan 15 is installed inside the air guide cavity 13.

[0050] In this embodiment, when rice bran and germ rice fall downward, the second air intake fan 15 operates to guide the external air into the air guide cavity 13 on the air guide pipe 14, and the air is guided into the bottom shell 1 through the second air intake cavity 11, and then the air is blown toward the rice bran and germ rice, thereby separating the rice bran and germ rice.

[0051] When the air guide cavity 13 absorbs gas, in order to prevent dust from being sucked into the device, Figure 1-Figure 2 As shown, a filter screen 12 is installed inside the air guide cavity 13 , and the filter screen 12 is located on the air intake side of the second air intake fan 15 .

[0052] In this embodiment, when the second air intake fan 15 is working and the gas is guided into the air duct 14 by the second air intake fan 15, the gas is filtered by the filter screen 12 to remove dust in the gas.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
