Description

Technical Field

[0001] This invention relates to the field of rice processing technology, specifically to a rice-brown separation and color sorting device and method. Background Technology

[0002] The rice processing steps include screening, destoning, magnetic separation, hulling, paddy rice separation, milling, color sorting, polishing, and packaging. Hulling refers to removing the husk from paddy rice to make brown rice. After hulling, about 20% of the paddy rice remains unhulled. The hulled material is first separated by air separation, and then the paddy rice and brown rice are separated by a paddy rice separation device. The unhulled brown rice is then sent back to the hulling machine for processing.

[0003] The physical properties of paddy rice and brown rice in a grain-brown mixture differ in terms of grain size, specific gravity, elasticity, coefficient of friction, and suspension velocity. Grain-brown rice separation equipment can be divided into three categories based on the main differences in these properties: those based on particle size, such as various brown rice sieves; those based on elasticity, such as buckyballs; and those based on specific gravity, such as gravity grain-brown rice separators. Due to the differences in particle size, specific gravity, elasticity, coefficient of friction, and suspension velocity between paddy rice and brown rice, an automatic grading phenomenon occurs in the grain-brown rice mixture during movement, causing the paddy rice layer to float on top of the brown rice layer. The above three types of grain-brown rice separation equipment all utilize the differences in one or more of these properties for separation.

[0004] During the hulling process, japonica rice has a thinner and looser husk than indica rice, and its outer fuzz is denser and longer. Therefore, japonica rice is easier to hull in a ridge-making machine. However, in actual operation, japonica rice is often mixed with indica rice, such as red rice. Red rice is a weedy rice belonging to the genus *Oryza* of the Poaceae family, which is similar to wild rice and grows alongside japonica rice. Consequently, during the hulling of japonica rice, the rotation speed of the rubber rollers inside the ridge-making machine... The method is adapted to japonica rice but not to indica rice, so some indica rice (i.e., red rice) often enters the rice-hulled rice separator without being completely hulled. The rice-hulled rice separator separates this unhulled indica rice and sends it back to the rice-hulling machine for processing. This causes some indica rice to be subjected to repeated hulling pressure, resulting in breakage and broken rice. To address this, we propose a rice-hulled rice separation color sorting device and method. Summary of the Invention

[0009] Preferably, the inner wall of the processing sleeve is provided with multiple slots, and the shape of the slots is similar to the appearance of red rice. The processing sleeve is provided with a discharge frame, and both the discharge frame and the inner wall of the processing sleeve are provided with filter holes.

[0010] Preferably, the circular disc frame is provided with an annular groove inside, and an annular rack is provided inside the annular groove. The end of the rubber roller is equipped with a fixing post, and the end of the fixing post is located inside the annular groove. A gear body for meshing with the annular rack is provided on the fixing post.

[0011] Preferably, the sorting unit includes a fixed tank located below the brown rice discharge bin, and the fixed tank is fixedly connected to the inner wall of the support body. Inside the fixed tank, there is a processing tank for rotatable connection with its inner wall. The inner wall of the processing tank is provided with an annular filter screen. The feed end of the fixed tank is in communication with the discharge end of the brown rice discharge bin. Inside the processing tank, there are multiple tray frames.

[0012] Preferably, the annular filter screen is made of stainless steel.

The tray frame has multiple filter holes and multiple function panels. One end of each function panel is connected to an annular filter, and the other end of each function panel is equipped with a magnetic end for sliding connection with the inner wall of the sealing sleeve. An electromagnet is installed inside the sealing sleeve, and when the electromagnet is energized, it generates a repulsive force on the magnetic end.

[0014] Preferably, the fixed tank is provided with an indica rice discharge port, the support body is provided with a receiving port, and the bottom of the processing tank is provided with a japonica rice discharge port, which is located above the receiving port.

[0015] Preferably, the power unit includes a motor body disposed inside the support body, wherein the output end of the motor body is provided with a bevel gear one, and a bevel gear two is disposed inside the support body, and a rotating shaft for rotatably connecting with the inner wall of the support body is installed at the bottom of the bevel gear two, a conveyor belt one is connected between the rotating shaft and the rice discharge pipe, and a conveyor belt two is connected between the output end of the motor body and the end of the drive column.

[0016] A method for using a grain sorting and color separation device includes the following steps:

[0017] S1. The material is poured into the separator. The processed brown rice enters the color sorter for color sorting. According to the color sorting results, the brown rice, unseparated rice husks and red rice are discharged into the brown rice discharge bin, rice husk discharge bin and red rice discharge bin respectively.

[0018] S2. Start the motor body, which drives the drive shaft and the rice discharge pipe to rotate through the second conveyor belt, the first bevel gear, the second bevel gear, the rotating shaft and the first conveyor belt;

[0019] S3. Red rice enters the processing sleeve. Some of the red rice falls into the slot and is confined there. The drive column drives the rubber roller to rotate through the ring connecting frame. The rubber roller acts on the red rice in the slot and on the inner wall of the processing sleeve to peel off the husk. The red rice and husk in the slot are separated by the rubber roller. The rubber roller acts on the red rice that has not entered the slot in a ring motion. When it moves from bottom to top and is close to the top, the husk at the top will fall off with the red rice under the action of gravity. The red rice is filtered by the filter holes, and the husk is discharged to the outside through the air intake.

[0020] S4. The japonica rice discharge pipe and the processing tank rotate. The indica rice enters the indica rice discharge pipe on the fixed tank through the annular filter screen, while the japonica rice falls into the japonica rice discharge pipe through multiple filter screen holes. During the sorting process, the electromagnet is energized at regular intervals, and the magnetic end causes the control panel to act on the annular filter screen. The sorting of japonica rice and indica rice is completed, and the red rice paddies are automatically hulled and separated.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention utilizes rubber rollers to separate the husks of red rice. The rollers are driven by a drive column to separate the red rice within the processing tank, eliminating the need to return the rice to the grain-setting machine for husk separation. Simultaneously, the air intake and filter holes separate the red rice from the husks, improving efficiency and reducing the broken rice rate. Furthermore, based on the different shapes of indica and japonica rice, the two types are separated through a fixed tank, processing tank, annular filter, tray frame, and filter holes, effectively improving the overall separation efficiency and quality.

[0023] 2. This invention utilizes the processing tank to make the brown rice falling on the tray body rotate synchronously with it, so that under the action of centrifugal force, the brown rice is thrown onto the surface of the annular filter screen. The indica rice passes through the annular filter screen and enters between the fixed tank and the processing tank, and falls out along the indica rice discharge pipe. Correspondingly, the japonica rice passes through the filter holes on multiple tray bodies in sequence and enters the japonica rice discharge pipe, and is discharged from the inside to the outside, so as to achieve the purpose of screening japonica rice and indica rice.

[0024] 3. This invention utilizes the timed energization of an electromagnet to apply force to the annular filter screen via its magnetic end, thereby preventing the filter screen from becoming clogged and improving its sorting efficiency. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-14This invention provides a technical solution: a rice-hulled rice separation and color sorting device and method. This invention addresses the problem in the prior art: in existing rice-hulled rice separation devices, some indica rice (i.e., red rice) often enters the rice-hulled rice separator without being completely hulled; the rice-hulled rice separator screens out this unhulled portion of indica rice and sends it back to the rice sorting machine for processing, causing some indica rice to be subjected to repeated hulling pressure and breakage, resulting in broken rice (i.e., broken rice). The device includes a machine body 1, which includes a support body 11 and a color sorting machine body 12 fixedly installed on the support body 11. A separator 13 is fixedly installed on the color sorting machine body 12. Further, the discharge end of the separator 13 and the inlet end of the color sorting machine body 12 are connected. In a connected state (the discharge end here refers to the brown rice discharge end of separator 13), when the hulled brown rice and rice husks enter separator 13 for separation, the brown rice enters the color sorter body 12 along the aforementioned discharge end. At this time, the brown rice may also contain unhulled red rice (i.e., unhulled indica rice; this invention mainly targets red rice, and the unhulled indica rice will be referred to as red rice below). Under the action of the color sorter body 12, the red rice, rice husks, and brown rice (the hulled indica rice and the hulled japonica rice) are separated according to the optical detection system, signal processing system, and separation execution system within it. The color sorter body 12 is equipped with red rice discharge bin 121, rice husk discharge bin 122, and brown rice discharge bin at equal intervals. 123, wherein the support body 11 is equipped with a barrel-shaped collection bin for collecting rice husks, and the barrel-shaped collection bin is located below the rice husk discharge bin 122. If the red rice is then returned to the hulling machine for hulling, since this step mainly targets japonica rice, the force exerted by the hulling machine on the red rice is relatively small, requiring multiple passes to complete the hulling. During these multiple hulling processes, the red rice is prone to breakage due to repeated force. Therefore, this invention provides an action unit 2 below the red rice discharge bin 121 for corresponding hulling processing of the red rice. This action unit 2 effectively performs the corresponding hulling work on the red rice, eliminating the need to return it to the hulling machine for further hulling, thus improving efficiency and avoiding... Multiple hulling processes result in broken rice in the red rice. Furthermore, the japonica rice may contain some hulled indica rice. To ensure that the separated rice is of the same type and avoids further processing, this invention includes a sorting unit 3 below the brown rice discharge bin 123 for separating the indica and japonica rice in the brown rice. Japonica rice is oval-shaped and relatively short and thick. While some brands offer long-grain japonica rice, it is still significantly shorter and thicker than indica rice. This sorting unit 3 can separate the japonica and indica rice accordingly. The support body 11 contains a power unit 4 for synchronously driving the action unit 2 and the sorting unit 3, ensuring that indica and japonica rice can be simultaneously sorted during the red rice processing.

[0042] For details, see attached. Figure 1-3 As shown: After being processed by the hulling machine, the rice husks and brown rice enter the separator 13 for separation. At this time, the rice husks and brown rice are separated. The brown rice may contain unhulled red rice, hulled japonica rice, and hulled indica rice. Then, it enters the color sorter 12 for color sorting. The three types of rice are sorted out by the optical detection system, signal processing system, and separation execution system. The red rice in the red rice discharge bin 121 will be hulled by the action unit 2. The hulled indica rice and japonica rice will be further refined by the sorting unit 3. The power unit 4 can effectively control the action unit 2 and the sorting unit 3 to work synchronously, so as to process the brown rice quickly and effectively.

[0043] As a further limitation of the present invention, the functional unit 2 includes a processing sleeve 21 fixedly installed on the inner wall of the support body 11. A square discharge bin 5 is installed on the support body 11, and the square discharge bin 5 is fixedly connected to the outer wall of the processing sleeve 21. The processing sleeve 21 is located below the red rice discharge bin 121, and the discharge end of the red rice discharge bin 121 penetrates through the inner wall of the processing sleeve 21 and extends into it. Circular disc frames 22 are fixedly installed at both ends of the processing sleeve 21, and multiple air intakes 23 are provided on the circular disc frames 22. Further, air intake pipes are also installed on these multiple air intakes 23, and these air intake pipes are connected to a fan. Since the fan and air intake pipes are existing technologies, the present invention does not describe them in detail. The suction power of the air duct can be controlled according to the program and the fan. The suction power should not be too high; it should be sufficient to pick up relatively light rice husks. A drive column 24 is provided at one end of the processing sleeve 21, and the end of the drive column 24 penetrates the inner wall of one circular disc frame 22 and extends into the interior of the other circular disc frame 22. The drive column 24 is rotatably connected to the inner walls of the two circular disc frames 22. Further, the outer end of the drive column 24 is rotatably connected to the inner wall of the support body 11, and the area near the end of the drive column 24 is connected to a component on the power unit 4, allowing the drive column 24 to rotate under the action of the power unit 4. An annular connection is fixedly installed on the area of ​​the drive column 24 inside the processing sleeve 21. A frame 25 is used, and a rubber roller 26 for processing red rice is installed on the annular connecting frame 25. The rubber roller 26 is rotatably connected to the annular connecting frame 25 so that the annular connecting frame 25 rotates synchronously with the rubber roller 26 as it rotates with the drive column 24. The inner wall of the processing sleeve 21 is provided with multiple slots 27. It should be noted that the size of the slots 27 is similar to the size of normal red rice (the size of the slots 27 is slightly larger than the red rice so that the red rice can enter the slots 27). The slots 27 are rounded and chamfered. When the red rice enters the slots 27, some of it will get stuck in the slots 27. Specifically, as the red rice enters the processing sleeve 21, some of the red rice falls to the bottom. Inside the slot 27, there is also a portion of the rice grains on the inner wall of the processing sleeve 21. As the rubber roller 26 rotates with the drive column 24 via the annular connecting frame 25, the rubber roller 26 acts on the red rice grains, separating them. At the same time, the rice husks on the outer surface of the red rice grains are subjected to force and leave the slot 27. The red rice grains on the inner wall of the processing sleeve 21 will perform synchronous circular motion (i.e., gradually move upward) under the action of the rubber roller 26. In the initial state, compared with the slot 27 at the lower position, the slot 27 at the higher position contains less red rice grains. As a result, this portion of red rice grains will enter the slot 27 at the higher position and be separated under the action of the rubber roller 26, falling from the higher position. Meanwhile, the air inlet 23 is ventilated to suck out the red rice husks.Under the influence of gravity, the separated red rice will be at the bottom of the processing sleeve 21. Therefore, the present invention has installed a discharge frame 28 (located in the lowest point area) on the processing sleeve 21, and filter holes 29 are provided on both the discharge frame 28 and the inner wall of the processing sleeve 21. The filter holes 29 are used to filter the red rice (the rice husks act as a barrier), so that the red rice can pass through the filter holes 29 into the discharge frame 28, and then through the filter holes 29 on the discharge frame 28 into the square discharge bin 5. The red rice can be screened a second time through the filter holes 29 in the discharge frame 28.

[0044] It should be noted that the spacing between the rubber rollers 26 on the annular connecting frame 25 is the size of normal red rice grains. Since the red rice grains will accumulate between the rubber rollers 26 during the falling process, in order to quickly peel the red rice grains located between them, the present invention has a fixing post 202 fixedly installed at the end of the rubber roller 26. The circular disc frame 22 has an annular groove 20 inside, and the end of the fixing post 202 is located within the annular groove 20. An annular rack 201 is installed inside the annular groove 20, and the fixing post 202... 2. A gear body 203 is fixedly installed on the fixed post 202 at the end of the rubber roller 26 for meshing with the ring rack 201, so that when the rubber roller 26 rotates synchronously with the drive column 24 through the ring connecting frame 25, the gear body 203 on the fixed post 202 at the end of the rubber roller 26 meshes with the ring rack 201 and rotates, so that the fixed post 202 drives the rubber roller 26 to rotate synchronously on the ring connecting frame 25, thereby utilizing the rotation between multiple rubber rollers 26 to make the red rice grains between them subject to force and perform the hulling work;

[0045] As a further limitation of the present invention, the sorting unit 3 includes a fixed tank 31 fixedly installed on the inner wall of the support body 11, wherein the fixed tank 31 is located below the brown rice discharge bin 123, and the discharge end of the brown rice discharge bin 123 penetrates through the inner wall of the fixed tank 31 and extends into its interior. A processing tank 32 for rotatable connection with its inner wall is provided inside the fixed tank 31, and the brown rice discharge bin 123 is located above the processing tank 32. An annular filter 33 is provided on the inner wall of the processing tank 32. The annular filter 33 is made of stainless steel wire and has a certain deformation capacity. Further, the size of the annular filter 33 is the normal size of indica rice. Because japonica rice is coarser, it cannot pass through the annular filter 33. An indica rice discharge port 30 is provided on the fixed tank 31, and multiple trays are fixedly installed inside the processing tank 32. The processing tank 32 has multiple tray frames 34 installed in parallel and equidistant positions inside the tank. Each tray frame 34 has multiple filter holes 36 with the same size as normal japonica rice. Sealing sleeves 35 are fixedly installed on the tray frames 34. Each tray frame 34 has multiple function panels 37, one end of which is connected to an annular filter 33. The other end of which is equipped with a magnetic end 38 for sliding connection with the inner wall of the sealing sleeve 35. An electromagnet 39 is installed inside the sealing sleeve 35. When the electromagnet 39 is energized, it generates a repulsive force on the magnetic end 38. A receiving pipe 301 is fixedly installed on the support body 11. A japonica rice discharge pipe 302 is installed at the bottom of the processing tank 32 and is located above the receiving pipe 301.

[0046] As a further limitation of the present invention, the power unit 4 includes a motor body 41 fixedly installed inside the bracket body 11, wherein a bevel gear 42 is installed at the output end of the motor body 41, and a bevel gear 43 is provided inside the bracket body 11. A rotating shaft 44 for rotatably connecting with the inner wall of the bracket body 11 is installed at the bottom of the bevel gear 43. A conveyor belt 45 is connected between the rotating shaft 44 and the rice discharge port 302, and a conveyor belt 46 is connected between the output end of the motor body 41 and the end of the drive column 24.

[0047] When the motor body 41 starts, its output end drives the first bevel gear 42 and the second conveyor belt 46 to rotate. During the rotation of the first bevel gear 42, it meshes with the second bevel gear 43 to rotate, which in turn drives the bottom shaft 44 and the first conveyor belt 45 to rotate. Since the ends of the second conveyor belt 46 and the first conveyor belt 45 are respectively connected to the drive column 24 and the rice discharge pipe 302, the drive column 24 and the rice discharge pipe 302 rotate synchronously. When the drive column 24 rotates, it drives the rubber roller 26 on it to rotate through the annular connecting frame 25. During the rotation, the fixing post 202 at the end of the rubber roller 26 performs a directional limiting action in the annular groove 20, and the gear body 2 on the fixing post 202... 03 will engage the ring rack 201 to rotate. When the red rice enters the processing sleeve 21, some of the red rice enters the slot 27 and is limited by it. During the rotation of the rubber roller 26, it acts on the red rice inside the slot 27 to separate the rice husk from the rice. At the same time, it also acts on the red rice on the inner wall of the processing sleeve 21 to make it move on the inner wall of the processing sleeve 21 until it moves to the slot 27 at the higher position and is separated by the force of the rubber roller 26. The separated red rice will pass through the filter hole 29 into the discharge frame 28 and fall into the square discharge bin 5 for collection. The rice husk will be sucked out by the air inlet 23, realizing the separation of red rice and rice husk.

[0048] During the rotation of the japonica rice discharge pipe 302, the processing tank 32 above it moves synchronously, causing the brown rice (a combination of japonica and indica rice) to move in a circular motion on the tray frame body 34. During the rotation, the indica rice enters between the fixed tank 31 and the processing tank 32 through the annular filter 33 and flows out from the indica rice discharge pipe 30. As the indica rice enters the tray frame body 34, it is generally not vertically downward due to gravity (it is slightly inclined), and is thus obstructed by the filter mesh 36. The japonica rice, on the other hand, falls through the filter mesh 36 to the next tray frame body 34, passing through the filters on multiple tray frame bodies 34. The rice is screened through holes 36, and finally flows from the rice discharge port 302 to the receiving port 301. When the processing tank 32 is rotating, the rice may clog the mesh of the annular filter 33. Therefore, the electromagnet 39 is periodically energized to generate a repulsive force on the magnetic end 38, so that the action panel 37 acts on the annular filter 33 to deform it, thereby ensuring that the mesh of the annular filter 33 is not clogged. Thus, the structural design of this invention can effectively separate unhulled red rice, hulled indica rice and japonica rice from brown rice, improving the separation quality while ensuring the separation efficiency.

[0049] A method for using a grain sorting and color separation device includes the following steps:

[0050] S1. The material is poured into the separator 13. The processed brown rice enters the color sorter body 12 for color sorting. According to the color sorting results, the brown rice, unseparated rice husks and red rice are discharged into the brown rice discharge bin 123, the rice husk discharge bin 122 and the red rice discharge bin 121 respectively.

[0051] S2. Start the motor body 41, which drives the drive shaft and the rice discharge pipe 302 to rotate through the second conveyor belt 46, the first bevel gear 42, the second bevel gear 43, the rotating shaft 44 and the first conveyor belt 45.

[0052] S3. Red rice enters the processing sleeve 21. Some of the red rice falls into the slot 27 and is confined there. The drive column 24 drives the rubber roller 26 to rotate through the annular connecting frame 25. That is, the rubber roller 26 acts on the red rice in the slot 27 and the inner wall of the processing sleeve 21 to peel it. The red rice and husk in the slot 27 are separated under the action of the rubber roller 26. The rubber roller 26 acts on the red rice that has not entered the slot 27 in a circular motion. When it moves from bottom to top and is close to the top, under the action of gravity, the husk at the top will be affected by the red rice and fall down with it. The red rice is filtered by the filter hole 29, and the husk is discharged to the outside through the air intake 23.

[0053] S4. The japonica rice discharge port 302 and the processing tank 32 rotate. The indica rice enters the indica rice discharge port 30 on the fixed tank 31 through the annular filter 33, while the japonica rice falls into the japonica rice discharge port 302 through multiple filter holes 36. During the sorting process, the electromagnet 39 is energized at regular intervals, and the action panel 37 is applied to the annular filter 33 through the magnetic end 38. The sorting of japonica rice and indica rice is completed, and the red rice is automatically hulled and separated.
