Description

Technical Field

[0001] This utility model relates to the field of rice milling machine technology, and in particular to a rice milling machine for retaining germ rice. Background Technology

[0002] With the development of rice milling technology, rice processing has gradually shifted from simply pursuing hulling efficiency to considering nutrient retention. Specialized rice milling technologies for different qualities of rice have emerged, among which germ-retaining rice has gained attention due to its ability to effectively retain different nutrients and meet the taste preferences of different consumers. In traditional technology, ordinary rice milling machines typically use a grinding structure to process brown rice. The rotating friction of a sand roller grinds the bran layer of the brown rice, completing the process of removing the bran and husk, thus obtaining germ-retaining rice. However, in actual operation, current rice milling machines either have excessive grinding force, directly damaging the rice germ during bran removal, resulting in a very low germ retention rate and significant nutrient loss, or insufficient grinding, leaving excessive bran residue on the outer layer of the brown rice, affecting the taste and appearance quality of the rice. This presents a technical problem of poor germ-retaining rice milling results. Utility Model Content

[0003] Therefore, it is necessary to provide a rice milling machine for rice with retained germ to address the technical problem of poor rice milling effect.

Each rice guiding space is distributed around the rotating shaft. The second sand roller is positioned between the discharge port and the flow guiding component. The driving component drives the rotating shaft to rotate, so that each decimeter space passes through the feed port sequentially in the direction of rotation of the rotating shaft.

[0005] In one embodiment, the diversion assembly includes a diversion fixing frame and diversion components. The diversion fixing frame is connected to the rotating shaft. There are multiple diversion components, each of which is connected to the diversion fixing frame.

[0011] In one embodiment, the guiding spaces of adjacent guiding components are staggered.

[0012] In one embodiment, the rice milling chamber includes a barrel, a first grinding ring, and a second grinding ring. The barrel is rotatably connected to the rotating shaft.

The rice can be evenly fed into the first milling roller through the separation of each decimeter space. The rice guided by the flow guiding component is separated and evenly fed into the second milling roller through the rice guiding space. This process divides the brown rice into multiple streams for milling, optimizes the flow path of the brown rice in the milling chamber, avoids germ damage caused by excessive local pressure, and effectively preserves the various nutrients of the germ-retained rice. This satisfies the different taste requirements of people with germ-retained rice and improves the milling effect of germ-retained rice. Attached Figure Description

[0030] like Figure 1 As shown, it is the germ-retaining rice milling machine 100 of this utility model, used for removing the husk from brown rice.

[0031] like Figures 1 to 3As shown, the rice milling machine 100 with retained germ rice includes: a frame 10 and a rice milling drive mechanism 20. The frame 10 includes a rice inlet hopper 11, a rice milling chamber 12, and a rice outlet hopper 13 connected sequentially from top to bottom. The rice milling chamber 12 has an inlet 121 and an outlet 122. The inlet 121 communicates with the rice inlet hopper 11, and the outlet 122 communicates with the rice outlet hopper 13. The rice milling drive mechanism 20 includes a rotating shaft 21, a flow-diverting assembly 22, a first sand roller 23, a flow-guiding assembly 24, a second sand roller 25, and a drive assembly 26. The rotating shaft 21 is rotatably mounted inside the rice milling chamber 12. The flow-diverting assembly 22, the first sand roller 23, the flow-guiding assembly 24, and the second sand roller 25 are connected in series. All sand rollers 25 are mounted on the rotating shaft 21. A flow-dividing assembly 22 is positioned between the inlet 121 and the first sand roller 23, dividing the space between the outer wall of the rotating shaft 21 and the inner wall of the rice milling chamber 12 into multiple decimeter spaces 27. These decimeter spaces 27 are distributed around the rotating shaft 21. A flow-guiding assembly 24 is positioned between the first sand roller 23 and the second sand roller 25, dividing the space between the outer wall of the rotating shaft 21 and the inner wall of the rice milling chamber 12 into multiple rice-guiding spaces 28. These rice-guiding spaces 28 are distributed around the rotating shaft 21. The second sand roller 25 is positioned between the outlet 122 and the flow-guiding assembly 24. A driving assembly 26 drives the rotating shaft 21 to rotate, thereby dividing the space between the first sand roller 23 and the second sand roller 25 into multiple rice-guiding spaces 28. Spaces 27, rotating around shaft 21, pass sequentially through inlet 121. Shaft 21 is rotatably mounted inside milling chamber 12. A flow-dividing component 22 is positioned between inlet 121 and the first sand roller 23, dividing the space between the outer wall of shaft 21 and the inner wall of milling chamber 12 into multiple decimeter spaces 27. A flow-guiding component 24 is positioned between the first sand roller 23 and the second sand roller 25, dividing the space between the outer wall of shaft 21 and the inner wall of milling chamber 12 into multiple rice-guiding spaces 28. A driving component 26 drives shaft 21 to rotate, ensuring that each decimeter space 27 passes sequentially through inlet 121 around shaft 21. Brown rice entering the milling chamber 12 through the feed inlet 121 is evenly fed into the first milling roller 23 for milling under the separation of each milling space 27. The rice is then evenly fed into the second milling roller 25 after being processed by the first milling roller 23 through the rice guiding space 28 formed by the flow guiding component 24. This process divides the brown rice into multiple streams for milling, optimizes the flow path of the brown rice in the milling chamber 12, avoids germ damage caused by excessive local pressure, effectively preserves the various nutrients of the germ-retained rice, meets the taste requirements of different people for germ-retained rice, and achieves the purpose of improving the milling effect of germ-retained rice.

[0032] The following text, combined with Figures 1 to 4 Further explanation is provided regarding the aforementioned germ-retaining rice milling machine 100.

[0033] To improve the ease of use of the splitter component 22 and reduce its operating costs, such as Figures 2 to 3As shown, the diversion assembly 22 includes a diversion fixing frame 221 and diversion components 222. The diversion fixing frame 221 is connected to the rotating shaft 21. There are multiple diversion components 222, each of which is connected to the diversion fixing frame 221. Adjacent diversion components 222 form a rice milling space 27 with the outer wall of the rotating shaft 21 and the inner wall of the rice milling chamber 12. The connection between the diversion components 222 and the fixing frame facilitates the disassembly and assembly of the diversion assembly 22, as well as the replacement and maintenance of the diversion components 222, thereby improving the ease of use of the diversion assembly 22 and reducing the operating cost of the diversion assembly 22.

[0034] To improve the installation accuracy and operational stability of the diverter 222, such as Figure 3 As shown, the diverter 222 includes a first fixing plate 223 and a diverter plate 224. The first fixing plate 223 is connected to the diverter fixing frame 221. The diverter fixing frame 221 is provided with a first mounting groove 225 for mounting the first fixing plate 223. The diverter plate 224 is connected to the first fixing plate 223. By using the first mounting groove 225 to connect with the first fixing plate 223 of the diverter 222, the diverter 222 can improve the installation accuracy and operational stability during use through the cooperation of the first fixing plate 223 and the first mounting groove 225, thereby achieving the purpose of improving the installation accuracy and operational stability of the diverter 222.

[0035] To reduce the damage rate of germ during processing, such as Figure 3 As shown, the flow guiding component 24 includes a flow guiding fixing frame 241 and a flow guiding component 242 connected to the flow guiding fixing frame 241. The flow guiding fixing frame 241 is connected to the rotating shaft 21. There are multiple flow guiding components 242, and each flow guiding component 242 is staggered with each flow diverting component 222. Through the staggered flow guiding component 24 and flow diverting component 22, the flow path of brown rice in the rice milling chamber 12 is optimized, the disordered movement of brown rice is avoided, and the purpose of reducing the damage rate of germ during processing is achieved.

[0036] To improve the installation accuracy and operational stability of the flow guide 242, such as Figures 3 to 4 As shown, the flow guide 242 includes a second fixing plate 243 and a flow guide plate 244. The second fixing plate 243 is connected to the flow guide fixing frame 241. The flow guide fixing frame 241 is provided with a second mounting groove 245 for mounting the second fixing plate 243. The flow guide plate 244 is connected to the second fixing plate 243. Similar to the flow divider 222, the cooperation between the second mounting groove 245 and the second fixing plate 243 of the flow guide 242 helps to improve the installation accuracy and operational stability of the flow guide 242, thereby achieving the purpose of improving the installation accuracy and operational stability of the flow guide 242.

[0037] To improve the milling precision and quality of rice during continuous processing, such as Figure 4As shown, the guide plate 244 includes a connecting part 246 and a scraping part 247. The connecting part 246 is connected to the second fixed plate 243. The scraping part 247 extends between the first sand roller 23 and the second sand roller 25 and the inner wall of the rice milling chamber 12. By extending the scraping part 247 between the first sand roller 23 and the second sand roller 25 and the inner wall of the rice milling chamber 12, not only can the flow of brown rice be guided by the scraping part 247, but the residual bran powder on the surface of the first sand roller 23 and the second sand roller 25 can also be cleaned in time, thereby improving the rice milling precision and rice milling quality in the continuous processing process.

[0038] In this embodiment, the first abrasive roller 23 is configured as a coarse abrasive roller with an abrasive particle size range of 60 to 80 mesh to suit the removal of the outer coarse bran. The second abrasive roller 25 is configured as a fine abrasive roller with an abrasive particle size range of 220 to 400 mesh to suit the fine removal of residual bran. The first abrasive roller 23 can be an 80-mesh diamond abrasive roller of Norton model GP205, which uses alumina abrasive and is suitable for the initial removal of the outer coarse bran of rice; or a 60-mesh abrasive roller of Hanko model JA113, which has paper-based alumina abrasive particles and can effectively remove the outer coarse bran. The second abrasive roller 25 can be a 400-mesh abrasive roller of Sunrise or a 220-mesh abrasive roller of Hanko model JA113.

[0039] To improve the quality of milled rice with retained germ, such as Figure 3 As shown, there are multiple second sand rollers 25, which are spaced apart. There are multiple flow guiding components 24, which are alternately arranged with each second sand roller 25. The rice guiding spaces 28 of adjacent flow guiding components 24 are staggered. By using the alternating arrangement of multiple second sand rollers 25 and flow guiding components 24, the number of rice milling stages for brown rice is increased, further improving the fine processing capability of brown rice and achieving the purpose of improving the rice milling quality of germ-retained rice.

[0040] like Figure 2 As shown, the rice milling chamber 12 includes a barrel body 123, a first grinding ring 124 and a second grinding ring 125. The barrel body 123 is rotatably connected to the rotating shaft 21. The first grinding ring 124 and the second grinding ring 125 are both installed inside the barrel body 123. The position of the first grinding ring 124 corresponds to the position of the first grinding roller 23, and the position of the second grinding ring 125 corresponds to the position of the second grinding roller 25.

[0041] To improve the ease of operation of rice milling machines, such as Figure 2As shown, the rice hopper 13 includes a body 131 and a baffle 132. The body 131 is provided with a rice discharge channel 133 and a chute 134. The rice discharge channel 133 is connected to the discharge port 122, and the chute 134 is connected to the rice discharge channel 133. The baffle 132 is slidably disposed in the chute 134 to block or open the rice discharge channel 133. The design of the baffle 132 of the rice hopper 13 can conveniently control the rice discharge speed and the amount of rice discharged, avoiding blockage and overflow during the rice discharge process, thereby improving the ease of operation of the rice milling machine.

[0042] When using the germ-retaining rice milling machine 100 provided in this application: brown rice is poured into the rice inlet hopper 11, and the brown rice enters the decimeter space 27 formed by the diversion component 22 through the feed inlet 121. The drive component 26 is started, driving the rotating shaft 21 to rotate, so that each decimeter space 27 passes through the feed inlet 121 in turn around the rotation direction of the rotating shaft 21, and the brown rice is evenly conveyed to the first grinding roller 23. The brown rice is coarsely ground by the first grinding roller 23 to remove the outer coarse bran. Under the guidance of the diversion component 24, the coarsely ground brown rice enters the rice guiding space 28 and is conveyed to the second grinding roller 25 to finely grind the brown rice to remove the residual fine bran. The processed germ-retaining rice enters the rice outlet hopper 13 through the discharge outlet 122. As needed, the opening or blocking of the rice outlet channel 133 is controlled by the sliding baffle 132 to complete the processing of germ-retaining rice.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
