Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to rice bran removal equipment for processing and producing selenium-enriched rice. Background Art

[0002] After the rice is hulled, the surface layer of the brown rice is ground into bran powder during the milling process. The residual bran powder will make the rice look gray and sticky to the touch, become turbid during cooking, and easily oxidize and become rancid, affecting the flavor and shelf life.

[0003] However, during the polishing process of the rice, the bran powder is mixed with the rice and cannot be quickly distinguished and collected.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figures 1-14 as well as Figure 17-Figure 19 , a rice bran powder removing equipment for processing and producing selenium-rich rice, including a frame 1, an intermediate layer 2 and a top plate 3 are welded on the frame 1, a feed port 4 is threadedly installed on the top plate 3, a pretreatment chamber 5 is welded at the bottom of the feed port 4, the frame 1 is located at the bottom of the pretreatment chamber 5 and a guide block 32 is welded, the guide block 32 is tilted, an inclined plate 6 and a collecting box 11 are welded on the frame 1, the bottom of the inclined plate 6 extends to the interior of the collecting box 11, the frame 1 is located on one side of the inclined plate 6 and a control box 9 is threadedly installed, a plurality of second drive motors are arranged in the control box 9, the output shaft of the second drive motor extends to the interior of the inclined plate 6 and a movable roller 8 is installed through a coupling, circular grooves 18 are evenly opened on the inclined plate 6, a plurality of circular grooves 18 are provided, and a first opening 19 is evenly opened in the circular groove 18 of the inclined plate 6 below the movable roller 8, and a separation component is provided on the intermediate layer 2.

[0042] The feed port 4 receives the rice to be processed, and the guide block 32 guides the pre-processed rice to the inclined plate 6. The inclined plate 6 is the core processing area. The rice flows on its surface. The circular grooves 18 opened in strips on the surface of the inclined plate 6 are used to plan the path of the rice, making it easy for the rice to enter the circular grooves 18 and slide. The movable roller 8 is driven by the second drive motor in the control box 9 and rotates above the inclined plate 6 to squeeze the rice, so that the bran powder is separated from the rice.

[0043] Furthermore, a first drive motor 7 is threadedly mounted on one side of the inclined plate 6 above the movable roller 8 , and an output shaft of the first drive motor 7 extends to the interior of the inclined plate 6 and is mounted with a rotating baffle 20 through a coupling, the bottom of the rotating baffle 20 is in contact with the surface of the inclined plate 6 .

[0044] A spray device is provided inside the pretreatment chamber 5 , which sprays water mist evenly on the surface of the rice grains. The spray device is composed of a water pump and a micron fan-shaped nozzle, and the nozzle is extended into the interior of the pretreatment chamber 5 .

[0045] The spray device adopts existing technology and is a conventional technical means, which will not be elaborated in detail here. The purpose of the spray device is to slightly moisten the bran powder layer on the surface of the rice grains. The moist bran powder will become more sticky and more likely to gather into clumps or adhere to the surface of the rice grains under the friction of the subsequent active roller 8, rather than flying in the form of dust.

[0046] The guide block 32 is arranged corresponding to the inclined plate 6. The middle part of the guide block 32 is threadedly mounted with a first guide plate 33. The bottom of the first guide plate 33 is evenly provided with through grooves 34. The aperture of the through grooves 34 is adapted to the rice.

[0047] The inclined design of the guide block 32 uses gravity to make the rice flow toward the inclined plate 6. The first guide plate 33 is installed in the middle of the guide block 32 by means of threads. The evenly distributed through grooves 34 at its bottom play a key role in diversion and uniform distribution. When the rice flows through the through grooves 34, it is dispersed into multiple streams and falls on the inclined plate 6 in a more uniform single layer or thin layer. At the same time, the first guide plate 33 can be replaced according to the rice aperture, thereby adjusting the aperture. The circular groove 18 on the inclined plate 6 also divides the rice into several streams, which facilitates the operation of the movable roller 8.

[0048] The surface of the movable roller 8 is provided with spiral ribs, which come into contact with the rice through the spiral ribs, thereby scraping off the bran powder and debris on the surface of the rice and polishing the surface of the rice.

[0049] The separation component includes a first fan 16 threadedly mounted on the middle layer 2, and an air outlet 24 is provided on the first fan 16, and the air outlet 24 is arranged toward the first opening 19. A second air inlet pipe 25 is installed on the rear side of the first fan 16, and a movable box 17 is also provided on the middle layer 2. Several recessed portions are provided on the top of the movable box 17, and a first electric telescopic machine 21 is provided in each recessed portion. A puncture needle 22 is provided at the end of the first electric telescopic machine 21, and a first air inlet pipe 23 is provided on one side of the movable box 17. The first air inlet pipe 23 is connected to the first fan 16 pipeline, and an air hole is provided in the middle of the puncture needle 22, which is connected to the first air inlet pipe 23 pipeline.

[0050] Furthermore, the movable box 17 is disposed at the bottom of the inclined plate 6 , and the puncture needle 22 is disposed corresponding to the first opening 19 , and the puncture needle 22 extends through the first opening 19 to be disposed above the inclined plate 6 .

[0051] When the rice slides to the first opening 19 opened on the inclined plate 6, the first fan 16 starts to work, and the wind is discharged through the first fan 16. The wind comes into contact with the rice and the bran powder through the first opening 19. The light bran powder will be blown up by the strong airflow, and the rice will be less affected by the airflow due to its own weight. Even if it is blown by the airflow, the rice will rise much lower than the bran powder, and the rice will eventually fall back onto the inclined plate 6 and continue to move downward.

[0052] The collecting box 11 is integrally formed with a discharge port 12 , a partition 13 is welded in the middle of the discharge port 12 , a first connecting plate 14 and a second connecting plate 15 are welded on the partition 13 , and a drying assembly is provided inside the collecting box 11 .

[0053] The first connecting plate 14 and the second connecting plate 15 extend to above the inclined plate 6, and the horizontal projection lengths of the first connecting plate 14 and the second connecting plate 15 are greater than the horizontal projection length of the curved plate 10. When the bran powder on the curved plate 10 falls vertically, it accumulates on the first connecting plate 14 and the second connecting plate 15, thereby preventing the bran powder from falling into the inclined plate 6.

[0054] Furthermore, the first connecting plate 14 is tilted toward one side of the inclined plate 6, and the end of the first connecting plate 14 away from the partition 13 is in contact with the inclined plate 6. The first connecting plate 14 and the second connecting plate 15 are integrally formed, and the bottom of the second connecting plate 15 is welded and fixed to the inclined plate 6.

[0055] The airflow generated by the first fan 16 passes upward through the gap and acts on the surface of the inclined plate 6. This upward airflow helps to lift the light bran powder on the inclined plate 6 and blow it toward the curved plate 10 installed on the side of the equipment.

[0056] The discharge port 12 is arranged at the bottom of the collecting box 11, and the discharge port 12 is arranged corresponding to the bottom of the inclined plate 6. The partition 13 divides the discharge port 12 into a first discharge port 121 and a second discharge port 122. The first discharge port 121 is a rice collection port, and the second discharge port 122 is a bran powder collection port.

[0057] Furthermore, the interior of the collecting box 11 is hollow, and a fourth drive motor is arranged on the side of the collecting box 11 close to the first discharge port 121. The output end of the fourth drive motor is equipped with a third rotating rod 41 through a coupling, and a second guide plate 42 is welded on the third rotating rod 41. A fixed plate 44 is welded to the interior of the collecting box 11, and the fixed plate 44 divides the interior of the collecting box 11 into two layers. A second fan 43 is threadedly installed at the bottom end of the collecting box 11, and the air outlet of the second fan 43 is vertically upward. A third guide plate 45 is welded to the top of the collecting box 11, and the third guide plate 45 is arranged above the air outlet of the second fan 43.

[0058] In particular, a third guide plate 45 is also provided at one end of the fixed plate 44 close to the second fan 43. The third guide plate 45 is arranged in an arc shape to facilitate receiving the rice blown by the second fan 43, so that the rice moves to the fixed plate 44. A third fan is installed on the top of the fixed plate 44. The third fan is inclined toward one side of the first discharge port 121. The third fan blows the rice on the surface of the fixed plate 44 back to the inside of the first discharge port 121.

[0059] Furthermore, a first filter plate 46 is provided on the surface of the second fan 43, and the first filter plate 46 is used to prevent rice from entering the fan, thereby ensuring the normal operation of the fan. A heating plate 47 is provided at the bottom of the collection box 11, and the second fan 43 is a hot air blower.

[0060] The surfaces on both sides of the second guide plate 42 are smooth, and rubber anti-slip pads are provided at the ends of the second guide plate 42 . The movable range of the second guide plate 42 is between the fixed plate 44 and the partition plate 13 .

[0061] The fixed plate 44 divides the box into two layers, upper and lower. When the second guide plate 42 collides with the partition 13, the rice enters the bottom of the collecting box 11 through the second guide plate 42, and then the second guide plate 42 switches to collide with the fixed plate 44. After being heated by the heating plate 47 at the bottom of the collecting box 11, it moves to the top of the second fan 43. The second fan 43 blows the rice to the top of the fixed plate 44, and the third fan arranged on the inner side of the top of the collecting box 11 blows the rice toward the first discharge port 121, so that the dried rice is collected.

[0062] The frame 1 is located above the collecting box 11 and is further welded with an arc-shaped plate 10 , on which a scraping assembly is provided.

[0063] The curved plate 10 is mainly used to collect and process the bran powder blown off the surface of the inclined plate 6 by the airflow of the first fan 16. A wet collection plate is attached to the curved plate 10 to adhere to the bran powder. The scraping assembly is responsible for regularly or continuously removing the bran powder accumulated on the inner surface of the curved plate 10.

[0064] A first cavity 36 is provided in the hollow interior of the curved plate 10, and arc-shaped grooves 26 are symmetrically provided on both sides of the curved plate 10. A slider 27 is slidingly provided inside the arc-shaped groove 26, and the slider 27 extends to the interior of the first cavity 36. A limiting groove 37 is provided on the inner side of the top of the first cavity 36, and a protrusion is provided on the top of the slider 27. The protrusion extends into the limiting groove 37. The limiting groove 37 is arranged in an arc shape. The part of the slider 27 extending into the curved plate 10 is threadedly mounted with a third drive motor 38, and a rack 40 is provided on the inner side of the bottom of the curved plate 10. A driving gear 39 is sleeved on the output shaft of the third drive motor 38, and the driving gear 39 is engaged with the rack 40.

[0065] When the third driving motor 38 rotates, the driving gear 39 rolls along the rack 40, thereby driving the entire slider 27 to move along the track of the arc groove 26, and further driving the scraping assembly to move.

[0066] The scraping assembly includes a second rotating rod 35 installed at the bottom of the slider 27 through a coupling. The bottom of the second rotating rod 35 is sleeved with a vertical plate 28. A first rotating rod 29 is hinged between the two vertical plates 28. A rotating sleeve 30 is sleeved on the upper part of the first rotating rod 29. A scraper 31 is welded on the rotating sleeve 30, and the scraper 31 is in contact with the lower surface of the curved plate 10.

[0067] The blade edge of the scraper 31 always contacts the lower surface of the arc plate 10. When the slider 27 is driven to move along the arc groove 26, the scraper 31 slides on the inner surface of the arc plate 10 and uses the contact force to scrape off the bran powder attached thereto.

[0068] Working principle:

[0069] Rice enters the pretreatment chamber 5 through the feed port 4. An internal spray device sprays micron-sized water mist at a rate of 0.2% of the rice flow rate, lightly moistening the surface of the rice grains. The moistened rice then falls through the inclined guide block 32 and is dispersed into multiple streams through the through grooves 34 of the first guide plate 33 threaded at its bottom, which are evenly spread onto the surface of the inclined plate 6. The circular grooves 18 on the inclined plate 6 further guide the rice into a single layer of flow.

[0070] The first drive motor 7 drives the rotating baffle 20 to adjust its opening, thereby controlling the flow of rice on the inclined plate 6. The rotating baffle 20 deflects, thereby driving a through hole formed between the rotating baffle 20 and the inclined plate 6. The rice moves through the through hole to the bottom of the rotating baffle 20. When a certain amount of rice enters under the rotating baffle 20, the rotating baffle 20 is rotated to continue to prevent the rice from falling. The second drive motor in the control box 9 drives the movable roller 8 to rotate. The movable roller 8 continuously rubs against the rice grains on the inclined plate 6 to remove bran powder and polish the surface.

[0071] When the rice flows to the first opening 19 of the inclined plate 6, the first fan 16 on the middle layer 2 blows air upward through the air outlet 24, and the light bran powder is blown up. When the first opening 19 is blocked, the first electric telescopic motor 21 on the top of the movable box 17 pushes the puncture needle 22 through the first opening 19 and pierces the rice pile. The air holes in the needle release air to break up the agglomerated bran powder and rice, and the raised bran powder is blown onto the curved plate 10 welded to the frame 1;

[0072] The debranched rice falls into the collecting box 11, and the fourth drive motor drives the third rotating rod 41 to drive the second guide plate 42 to switch positions, guiding the rice to the bottom heating plate 47 for drying. After the drying is completed, the position of the second guide plate 42 is switched so that the second guide plate 42 contacts the fixed plate 44, and the rice is blown into the first discharge port 121 by the force of the second fan 43 and the third fan.

[0073] The third drive motor 38 drives the driving gear 39 to roll along the rack 40, driving the slider 27 to slide in the arc groove 26. The second rotating rod 35 at the bottom of the slider 27 links the vertical plate 28 and the first rotating rod 29, so that the scraper 31 on the rotating sleeve 30 scrapes off the bran powder attached to the inner wall of the arc plate 10. The scraped bran powder is discharged separately through the second discharge port 122, and there is no cross contamination with the polished rice throughout the process.

[0074] In this embodiment, the air volume discharged by the first fan 16 toward the first opening 19 is adjustable. If the air volume is too small, the bran powder is not blown onto the curved plate 10, the first connecting plate 14, and the second connecting plate 15, or falls onto the inclined plate 6 after being blown up or collides with the lower surface of the second connecting plate 15, the second guide plate 42 is adjusted so that the second guide plate 42 moves to the side that contacts the fixed plate 44, so as to prevent rice with incomplete separation of bran powder from entering the drying component and directly discharge it for collection and manual sorting.

[0075] If the air volume is moderate, the bran powder is separated from the rice, the rice moves downward normally, the bran powder is blown up, and a small part that is not stuck to the curved plate 10 falls onto the first connecting plate 14 and the second connecting plate 15. The first connecting plate 14 and the second connecting plate 15 are inclined, and also drive the bran powder into the second discharge port 122. The device operates normally, and the air volume is slightly increased at this time.

[0076] If the air volume is too large, the rice and bran powder will be blown onto the curved plate 10 and stick to it. The amount of rice collected in the collecting box 11 will have a large error from the preset amount, and the processing operation will be stopped and the staff will intervene for maintenance.

[0077] If the first opening 19 is blocked by wet bran powder and rice, the situation at the first opening 19 is continuously captured by an external camera. If the rice is obviously accumulated, the movable box 17 and the first electric telescopic machine 21 intervene. The first electric telescopic machine 21 drives the puncture needle 22 to extend into the first opening 19, and lifts up the part blocking the first opening 19. At the same time, air is supplied by the first fan, and the strong airflow blows the blockage completely to the curved plate 10 to stick to it, so as to avoid affecting the normal drying and conveying operations of other rice.

[0078] Furthermore, the water spraying amount of the spray device is set to A, the speed of the second drive motor in the control box 9 is set to V, that is, the speed of the movable roller 8 is V, and a first camera is provided on the outside to perform real-time detection on the inclined plate 6.

[0079] When A is less than 0.15% of the rice flow rate, the first camera detects that when the movable roller 8 on the inclined plate 6 is being polished, the bran powder layer is not completely wetted, the viscosity is not activated, the movable roller 8 is in greater contact with the rice, and when the rice rubs against the movable roller 8, the bran powder flies. At the same time, the first fan 16 blows air to the first opening 19. When the polished bran powder and rice pass through the first opening 19, a large amount of dust is generated when the first fan 16 blows the bran powder and rice. The staff adjusts the water flow rate of the spray device.

[0080] When 0.15%≤A≤0.25%, the rice is normally moist, and no obvious dust is raised when it is polished by the movable roller 8. At the same time, when it passes through the first opening 19, the first fan 16 blows the rice and bran powder, and the rice moves downward normally. The bran powder clumps and is easily blown away by the airflow;

[0081] When A>0.25% of the rice flow rate, the rice is over-moistened. When it is polished by the movable roller 8, the first camera detects that the rice passing through the movable roller 8 is broken. At the same time, when the rice and bran powder pass through the first opening 19, the first fan 16 supplies air normally, but the bran powder blown upward is significantly reduced, and the first opening 19 is blocked. At this time, the first opening 19 is punctured and unblocked by the puncture needle 22 on the movable box 17, and the water output of the spray device is adjusted at this time.

[0082] At the same time, the rotation rate of the active roller 8 affects the polishing effect. When A=0.2%, the rotation rate is analyzed:

[0083] When V is less than 250 rpm, the contact speed between the movable roller 8 and the rice is low, the polishing effect is poor, and the weight of the polished rice after processing is much greater than the theoretical weight of polished rice. The polished rice after processing is placed back at the feed port 4 for reprocessing;

[0084] When 250≤V≤350rpm, the weight of the polished rice processed is consistent with the theoretical polished rice weight range. At the same time, the polished rice after adding is manually inspected and it is found that the polished rice is generally polished and complete, and the rice grains are not greatly damaged, the surface is smooth, and the rice is less broken, then the movable roller 8 is controlled to work normally;

[0085] When V>350rpm, the first camera detects that the movable roller 8 drives the rice to bounce, and the rice grains bounce out of the circular groove 18, which proves that the impact kinetic energy of the movable roller 8 is large, the rice grains collide violently with the inclined plate 6, and there is an abnormal sound. After the polished rice is processed, manual inspection finds that there are many broken rice. At this time, the movable roller 8 and the second drive motor are repaired.

[0086] Furthermore, when analyzing the blockage of the first opening 19, A and V are comprehensively considered. When A>0.25% and V>350rpm, the excessive humidity causes the rice to become damp, and the high-speed impact causes the rice grains to break, increasing the possibility of them sticking together, causing the first opening 19 to become blocked, requiring repeated intervention with the puncture needle 22.

[0087] When the first camera detects dust, the rice is relatively dry and the bran powder is not completely agglomerated. When the movable roller 8 contacts the rice at a relatively high rotation speed, it takes the rice away from the circular groove 18, that is, A < 0.15%, V > 350 rpm, causing the rice to be lifted up and then fall onto the inclined plate 6 and pile up in disorder. At this time, when the rice passes through the first opening 19, the blowing effect of the second fan 16 is poor, and the rice not in the circular groove 18 cannot be blown. As a result, part of the bran powder in the rice is not blown onto the curved plate 10 by the second fan 16. This part of the bran powder and the rice enter the collecting box 11 through the first discharge port 121 at the same time, resulting in a high bran content in the processed rice.

[0088] When the first camera detects that the bottom of the movable roller 8 of the inclined plate 6 is blocked, the amount of rice falling downward is abnormally small. At this time, A and V are synchronously analyzed. The rice is too damp and the rotation speed of the movable roller 8 is low, that is, A>0.25%, V<250rpm, causing the rice to accumulate in the circular groove 18 at the bottom of the movable roller 8. The movable roller 8 crushes the accumulated rice agglomerates, resulting in an increase in the broken rice rate and a deterioration in the bran removal effect. As a result, the rice entering the first discharge port 121 does not meet the normal processing standards and becomes inferior rice.

[0089] When the rice entering the first discharge port 121 is weighed, if the weight of the rice is greater than the preset polished rice weight, it is determined that the rice entering the first discharge port 121 has too high a bran content. At the same time, the first camera does not detect obvious dust. At this time, the moisture level of the rice is analyzed and it is found that A is less than 0.15%. At this time, the movable roller 8 also rotates at a slow speed. The speed is adjusted and the water spraying amount is increased to improve the rice processing accuracy.

[0090] Example 2

[0091] In the above embodiment, in order to further ensure that the bran powder does not fall back onto the inclined plate 6 and to prevent the scraped wet bran powder from falling onto the inclined plate 6 or onto the ground, Figure 15-16 On the basis of the first embodiment, it is proposed to weld and install a second filter plate 48 on the front side of the curved plate 10. The second filter plate 48 is installed vertically, and the top of the second filter plate 48 is screwed to the frame 1 for easy disassembly and reinstallation. A second opening 49 is opened on the second filter plate 48. The second opening 49 has the same aperture as the first opening 19, but the density of the second opening 49 is much greater than the density of the first opening 19, so that when the first fan 16 blows the rice with a strong wind force, the bran powder moves through the second opening 49 to the side of the second filter plate 48 close to the curved plate 10, further ensuring the separation of bran powder and rice.

[0092] Furthermore, if the wind force of the first fan 16 is too large or there is too much bran powder, the second opening 49 on the second filter plate 48 is blocked. The second electric telescopic machine 52 is threadedly installed on the frame 1, and the output end of the second electric telescopic machine 52 is arranged toward the middle of the second filter plate 48, and a connecting rod is provided on the output end. The upper and lower ends of the connecting rod are welded with a connecting frame 51, and the connecting frame 51 is arranged in an L shape. The ends of the two connecting frames 51 are installed with a brush roller 50 through a coupling. The brush roller 50 conflicts with the surface of the second filter plate 48 close to the inclined plate 6 side. The second electric telescopic machine 52 drives the brush roller 50 to brush the bran powder or rice in the second opening 49 on the second filter plate 48 and brush it onto the first connecting plate 14 and the second connecting plate 15. The bran powder is collected by the external induced draft fan to avoid accumulation on the first connecting plate 14 and the second connecting plate 15.

[0093] In particular, at this time, the scraper 31 on the rotating sleeve 30 on the curved plate 10 can be removed and replaced with an inclined fourth guide plate 53. The fourth guide plate 53 is inclined toward one side of the curved plate 10, which further facilitates the bran powder to fall onto the first connecting plate 14 and the second connecting plate 15, thereby facilitating the collection of the bran powder.
