Description

Technical Field

[0001] The invention relates to the technical field of rice processing equipment, in particular to a rice pretreatment device for rice processing. Background Art

[0002] Rice, a staple food for over half of the world's population, is a processed grain derived from the seeds of the grass family Oryza sativa. Its plump, white grains are rich in carbohydrates, protein, B vitamins, and minerals like potassium and magnesium, providing sustained energy. Rice comes in a wide variety, categorized by type: indica rice, japonica rice, and glutinous rice. Indica rice is long and slender, resulting in a fluffy, dry texture perfect for stir-frying; japonica rice is short and round, with a soft, sticky, and smooth texture, making it a preferred staple rice. Glutinous rice is extremely sticky and is often used in snacks like rice dumplings and rice cakes. Depending on the processing precision, there are brown rice varieties that retain the bran layer, rich in dietary fiber and suitable for those pursuing a healthier diet; and polished rice with the outer layer removed, resulting in a smoother texture and easier digestion.

[0003] In rice processing, soaking is a critical pretreatment step. This process not only effectively removes starch from the rice surface, improving the finished product's texture, but also accelerates rice softening through water penetration, significantly improving subsequent processing efficiency. However, existing soaking techniques have significant limitations. Traditional processes often employ a one-size-fits-all soaking method for different rice varieties, such as polished rice, brown rice, and glutinous rice, without tailoring treatment to each rice type. This crude approach is prone to two major problems: over-soaking leads to significant nutrient loss, particularly irreversible damage to water-soluble nutrients such as B vitamins and minerals; and insufficient soaking prevents the rice kernels from absorbing sufficient water, resulting in undercooked rice after processing, seriously affecting the quality and taste of the finished product. Therefore, those skilled in the art have proposed a rice pretreatment device for rice processing to address these technical issues. Summary of the Invention

[0014] Working principle: When processing rice into rice products, the agglomeration processing mechanism is started first, and the rice to be processed is coordinated with the conveying equipment and the feeding pipe on the processing box, so that the rice to be processed enters the primary screening plate in the processing box, and the rice falling on the primary screening plate is preliminarily screened for impurities and agglomerates through the sieve holes on the primary screening plate. After screening, the rice falls to the bottom through the sieve holes on the primary screening plate. At the same time, the driving motor on the processing box is started, and the rotating shaft of the driving motor drives the rotating seat in the processing box to rotate synchronously while rotating. The rotating seat drives the dispersion seat and the electrode patch thereon to rotate synchronously while rotating. The dispersing seat rotates in a step, and while rotating, it beats and separates the starch attached to the surface of the rice after the screening process of the primary screening plate, and also breaks up the lumps remaining in the rice again. The starch after beating and separation is then dispersed in the bottom space of the primary screening plate. After it comes into contact with the electrode patch on the dispersing seat, the electrode patch gives an electric charge to the starch floating in the space, so that the starch floating in the bottom space of the primary screening plate is affected by the attached electric charge to produce a clustering effect, and the volume and mass of the clustered starch increase, and then it falls synchronously with the falling of the rice, thereby completing the breaking up of lumps and starch dispersion before rice processing;Then the preliminary separation mechanism is started, and the rice processed by the agglomeration processing mechanism and the starch powder after the charged agglomeration fall onto the middle sieve plate. At this time, the strip vibrator at the bottom of the middle sieve plate is started. The strip vibrator generates vibration at the same time as it is started and synchronously transmits the vibration to the middle sieve plate, so that the rice falling on the middle sieve plate and the starch particles after agglomeration are re-screened out from the sieve holes thereon by vibration. At the same time, the vibration force generated by this screening is also used to separate the starch remaining on the rice surface again. After that, the rice after screening falls onto the strip vibrator and finally passes through the strip vibrator. The sieve holes on the surface of the shaped vibrator screen it again and then fall into the bottom of the strip vibrator for collection. At the same time, the air pump on the processing box is started. When the air pump is started, high-pressure gas is injected into the gas diversion box on the processing box through the connecting pipe. The high-pressure gas entering the gas diversion box is diverted through its internal flow channel, so that it forms a laminar state when discharged. The laminar high-pressure airflow discharged from the gas diversion box blows the rice and starch agglomerates formed after screening by the middle sieve plate, so that they hit the separation mesh plate on the surface of the separation box, which makes The starch agglomerates in the falling process pass through the mesh holes on the separation mesh plate and enter the separation chamber in the separation box for processing. On the other hand, the starch remaining on the surface of the rice can be separated again when it hits the separation mesh plate, so that the rice falls under the influence of gravity after separation, and the separated starch passes through the mesh holes on the separation mesh plate and enters the separation chamber in the separation box. Then, the dispersed starch and starch agglomerates entering the separation chamber are driven to move by the high-pressure gas and are gradually separated and processed by the collection bag on the mounting rack. Finally, the gas after multiple treatments is discharged into the The end of the separation chamber, and then the gas at the end of the separation chamber is discharged into the soaking wastewater in the separation cylinder through the exhaust pipe, so that the residual starch in the gas is adsorbed by the soaking wastewater in the separation cylinder, and then the gas after adsorption is discharged into the external environment through the one-way exhaust valve on the separation cylinder. At the same time, the staff can also pump the soaking water after soaking the rice through the liquid pump on the processing box, and then transport it through the cooperation of the connecting pipe, so as to transport it to the separation cylinder as a separation medium, and can also reduce the waste of water resources caused by the separation of residual starch in the gas, thereby completing the separation process of rice and starch on its surface;Then the adaptive soaking mechanism is started, and the rice processed by the preliminary separation mechanism falls to the bottom of the strip vibrator for collection, and then the suction pump on the processing box is started. When the suction pump is started, the rice that has undergone multiple processing at the bottom of the strip vibrator is sucked into the soaking water in the mounting seat with the help of the connecting pipe. When the rice is put into the soaking water on the mounting seat, the temperature sensor and liquid level sensor on the partition plate are used to collect the liquid level and temperature data information of the soaking water on the mounting seat in real time. At the same time, the rice soaked in the soaking water on the upper part of the mounting seat is monitored in real time through the separation chamber for the resistance data information of the soaking water. Due to the different types of rice and the degree of soaking, the monitored resistivity is also different. Then the conductivity transmitter on the processing box converts the original resistance signal collected by its separation chamber into a standard signal and transmits it to the PLC display controller on the processing box. After receiving the conductivity, temperature and liquid level data information transmitted by it, the PLC display controller uses a preset algorithm to calculate the conductivity value after temperature compensation, and compares it with the threshold set by the staff. The value comparison triggers a prompt light or sound effect, prompting the staff to discharge the fully soaked rice into the collection device by opening the lid for collection. At the same time, the soaking of the rice can also separate the residual starch on the rice surface from the soaking water, thereby completing the adaptive soaking treatment of different types of rice. At the same time, the cavitation separation mechanism is activated. While the adaptive soaking mechanism is soaking the rice on the mounting seat, the low-frequency driver at the bottom of the mounting seat is activated. The low-frequency driver simultaneously drives the concave drive seat on the mounting seat to rotate at a low frequency. The rotation of the mounting seat also drives the stirring seat on it to rotate, so that the soaked rice on the upper part of the mounting seat and the soaking water form a small vortex flow. At the same time, the ultrasonic generator on the concave drive seat is activated and generates ultrasonic waves. The vortex flow generated by the low-frequency rotation allows the rice grains to be evenly exposed to the ultrasonic waves. The ultrasonic waves generate cavitation bubbles in the water. When the bubbles burst, the microjets generated impact the surface of the rice grains, thereby stripping the residual starch on the rice grains, thereby completing the final stripping treatment of the starch attached to the rice surface.

[0015] The present invention provides a rice pretreatment device for rice processing. It has the following beneficial effects: 1. The present invention adds and sets an agglomeration processing mechanism. Before processing the rice, the mechanism can, on the one hand, non-damageably break up the agglomerates in the rice raw material by rotating and beating, thereby improving the uniformity of the subsequent rice during processing and the consistency of the subsequent rice products. On the other hand, the starch on the surface of the rice separated by beating can be charged, so that the starch separated from the rice surface produces a reunion effect, which is convenient for the subsequent separation of the starch on the rice surface and can also reduce the waste of water resources in the subsequent rice washing process, thereby improving the processing efficiency of the rice.

[0016] 2. The present invention adds and sets a preliminary separation mechanism. When processing rice, the mechanism can not only separate the starch on the surface of rice by vibration separation and high-speed airflow assistance, further peel off the stubbornly attached starch, and achieve efficient separation of starch on the rice surface, but also can collect and purify the treated rice in multiple ways through the cooperation of the collection bag and the soaking wastewater, and collect and purify the starch particles mixed in the gas. This double purification treatment method not only greatly reduces the amount of starch residue and makes the rice surface cleaner, but also can recycle the soaking wastewater, thereby having the advantages of both environmental protection and high efficiency.

[0017] 3. The present invention adds and sets an adaptive soaking mechanism. When processing rice, the mechanism monitors the temperature, conductivity, liquid level and other data information of the soaked rice in real time through dynamic determination of the conductivity threshold, thereby performing differentiated soaking treatments to different degrees according to different rice varieties. This treatment method can not only avoid the loss of nutrients caused by excessive soaking of rice, but also avoid the inability of rice grains to fully absorb water due to insufficient soaking of rice, as well as the phenomenon of undercooked products in subsequent processing, thereby ensuring the quality and taste of the finished rice products.

[0018] 4. The present invention adds and sets a cavitation treatment mechanism. When treating rice, the mechanism uses a treatment method that cooperates with ultrasound and low-frequency stirring to not only utilize the cavitation effect to achieve non-contact removal of residual starch on the surface of rice, but also causes less damage to rice grains than the traditional mechanical polishing removal method. In addition, this treatment method can also simultaneously remove tiny impurities such as pesticide residues or microorganisms remaining on the surface of rice, thereby achieving the dual functions of removing starch and cleaning the rice.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. 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.

[0022] Please see the attached Figure 1 -Attached Figure 3 , an embodiment of the present invention provides a rice pre-processing device for rice processing, comprising a processing box 1, which serves as a basic component of the entire device and is used to assemble and carry various processing mechanisms and their subordinate structural members; Please see the attached Figure 5 , an agglomeration processing mechanism, which is arranged in the upper middle part of one side of the interior of the processing box 1, is used to break up and disperse the agglomerates in the rice entering the interior thereof, and simultaneously process the starch attached to the surface of the rice; The agglomeration processing mechanism includes a feed pipe 2, which is fixedly connected to the upper middle part of one side of the processing box 1, and the interior of the feed pipe 2 is connected to the interior of the processing box 1. A primary screening plate 16 is fixedly connected to the upper middle part of one side of the interior of the processing box 1.

[0023] When the agglomeration processing mechanism is started, the rice to be processed is conveyed through the conveying equipment and the feed pipe 2 on the processing box 1, so that the rice to be processed enters the primary screening plate 16 in the processing box 1. The rice falling on the primary screening plate 16 is preliminarily screened for impurities and agglomerates through the sieve holes on the primary screening plate 16. After the screening process, the rice falls to the bottom through the sieve holes on the primary screening plate 16.

[0024] The agglomeration processing mechanism also includes a rotating seat 17, which is rotatably connected to the middle of one side inside the processing box 1. A plurality of dispersion seats 29 are arranged in a circular array near the edge inside the rotating seat 17. The middle of the dispersion seats 29 are all provided with electrode patches 32. A driving motor 11 is provided in the middle of the rear side of the processing box 1, and the output end of the driving motor 11 passes through the processing box 1 and is connected to the middle of the rotating seat 17.

[0025] At the same time, the drive motor 11 on the processing box 1 is started, and the rotating shaft of the drive motor 11 drives the rotating seat 17 in the processing box 1 to rotate synchronously while rotating. The rotating seat 17 drives the dispersion seat 29 and the electrode patch 32 thereon to rotate synchronously while rotating. The dispersion seat 29 beats and separates the starch attached to the surface of the rice after screening by the primary screening plate 16 while rotating.

[0026] At the same time, the remaining lumps in the rice are also broken up again, and then the starch after beating and separation is dispersed in the bottom space of the primary screening plate 16. After it comes into contact with the electrode patch 32 on the dispersion seat 29, the electrode patch 32 gives the starch floating in the space an electric charge, so that the starch floating in the bottom space of the primary screening plate 16 is affected by its attached charge to produce a clustering effect, and the volume and mass of the starch after clustering increase, and then it falls synchronously with the falling of the rice, thereby completing the breaking up of lumps and starch dispersion before rice processing.

[0027] Please see the attached Figure 4 and attached Figure 6 -Attached Figure 7 , a preliminary separation mechanism, which is arranged in the lower middle part of one side of the interior of the processing box 1, and is used to perform preliminary separation processing on the rice after being processed by the agglomeration processing mechanism and the starch attached to the surface thereof; The preliminary separation mechanism includes a middle sieve plate 18, which is provided at the middle and lower part of one side of the inner side of the processing box 1, and strip vibrators 19 are provided on both sides of the middle part of the bottom end of the middle sieve plate 18. A bottom sieve plate 20 is provided near the edge of the middle and lower part of the inner side of the processing box 1, an air pump 12 is provided at the middle and lower part of one side of the processing box 1, and a gas diversion box 10 is provided at the middle and lower part of one side of the front end of the processing box 1, and the interior of the gas diversion box 10 is connected with the interior of the processing box 1, and the exhaust port of the air pump 12 is connected with the interior of the gas diversion box 10 through a connecting pipe.

[0028] When the preliminary separation mechanism is started, the rice processed by the agglomeration processing mechanism and the starch powder after the charged agglomeration fall onto the middle sieve plate 18. At this time, the strip vibrator 19 at the bottom of the middle sieve plate 18 is started. The strip vibrator 19 generates vibration while starting and simultaneously transmits the vibration to the middle sieve plate 18, so that the rice falling on the middle sieve plate 18 and the starch particles after agglomeration are re-screened out from the sieve holes thereon by vibration. At the same time, the starch remaining on the surface of the rice is also separated again by the vibration force generated by this screening. After that, the rice after screening falls onto the strip vibrator 19, and finally falls to the bottom of the strip vibrator 19 for collection after being re-screened through the sieve holes on the surface of the strip vibrator 19.

[0029] The preliminary separation mechanism also includes a separation box 13. The separation box 13 is arranged in the lower middle part of one side of the rear end of the processing box 1, and the interior of the separation box 13 is connected to the interior of the processing box 1. A separation mesh plate 33 is arranged on the end of the separation box 13 close to the processing box 1. A separation cavity 36 is opened inside the separation box 13. A plurality of mounting racks 35 are equidistantly arranged inside the separation cavity 36, and a collection bag 34 is provided inside the mounting racks 35.

[0030] At the same time, the air pump 12 on the processing box 1 is started, and the air pump 12 injects high-pressure gas into the gas diversion box 10 on the processing box 1 through the connecting pipe. The high-pressure gas entering the gas diversion box 10 is diverted through its internal flow channel, so that it forms a laminar state when discharged. The laminar high-pressure airflow discharged from the gas diversion box 10 blows the rice after screening by the middle sieve plate 18 and the agglomerates formed after starch agglomeration, so that it hits the separation mesh plate 33 on the surface of the separation box 13.

[0031] On the one hand, the starch agglomerates in the falling process pass through the mesh holes on the separation mesh plate 33 and enter the separation chamber 36 in the separation box 13 for processing. On the other hand, the starch remaining on the surface of the rice can be separated again when it hits the separation mesh plate 33, so that after separation, the rice falls under the influence of gravity, and the separated starch passes through the mesh holes on the separation mesh plate 33 and enters the separation chamber 36 in the separation box 13.

[0032] The preliminary separation mechanism also includes a separation cylinder 6. A separation cylinder 6 is provided on one side of the rear end of the treatment box 1. Soaking wastewater 31 is injected into the interior of the separation cylinder 6. A one-way exhaust valve 30 is provided on the upper and middle part of one side of the separation cylinder 6. Two exhaust pipes 4 are equidistantly provided on the top of one end of the separation box 13 away from the treatment box 1, and the other end of the exhaust pipe 4 passes through the separation cylinder 6 and extends into the soaking wastewater 31. Sealing ring seats 15 are provided at the connection points at both ends of the exhaust pipe 4. The two exhaust pipes 4 are connected by a connecting seat 5. A liquid pump 14 is provided in the middle of the rear side of the treatment box 1. The liquid inlet of the liquid pump 14 is connected to the bottom of one side of the treatment box 1 through a connecting pipe, and the liquid outlet of the liquid pump 14 is connected to the upper and middle part of one side of the separation cylinder 6 through a connecting pipe.

[0033] Then, the dispersed starch and starch agglomerates entering the separation chamber 36 are driven to move by the high-pressure gas, and are gradually separated and processed by the collecting cloth bag 34 on the mounting frame 35. Finally, the gas after multiple treatments is discharged to the end of the separation chamber 36, and then the gas at the end of the separation chamber 36 is discharged into the soaking wastewater 31 in the separation cylinder 6 through the exhaust pipe 4, so that the residual starch in the gas is adsorbed by the soaking wastewater 31 in the separation cylinder 6, and then the gas after adsorption is discharged into the external environment through the one-way exhaust valve 30 on the separation cylinder 6.

[0034] At the same time, the staff can also pump the soaking water after soaking the rice through the liquid pump 14 on the processing box 1, and then transport it through the cooperation of the connecting pipe, so as to transport it into the separation cylinder 6 to serve as a separation medium. It can also reduce the waste of water resources caused by the separation of residual starch in the gas, thereby completing the separation process of rice and its surface starch.

[0035] Please see the attached Figure 3 , an adaptive soaking mechanism, which is arranged on the other side of the processing box 1, and is used to perform adaptive soaking treatment on the rice after being processed by the preliminary separation mechanism according to different types; The adaptive soaking mechanism includes a partition plate 21, a partition plate 21 is vertically arranged in the middle of the inner side of the processing box 1, a temperature sensor 27 is arranged in the middle and upper part of one side of the partition plate 21, and a liquid level sensor 28 is arranged in the middle and upper part of one side of the partition plate 21 near the edge, and a suction pump 9 is arranged in the middle and upper part of one side of the front end of the processing box 1. The feed port of the suction pump 9 is connected to the bottom side of the front end of the processing box 1 through a connecting pipe, and the discharge port of the suction pump 9 is connected to the middle and upper part of the other side of the front end of the processing box 1 through a connecting pipe.

[0036] When the adaptive soaking mechanism is started, the rice processed by the preliminary separation mechanism falls to the bottom of the strip vibrator 19 for collection, and then the suction pump 9 on the processing box 1 is started. When the suction pump 9 is started, the rice that has undergone multiple treatments at the bottom of the strip vibrator 19 is sucked into the soaking water in the mounting seat 24 with the assistance of the connecting pipe. When the rice is put into the soaking water on the mounting seat 24, the liquid level and temperature data information of the soaking water on the mounting seat 24 are collected in real time through the temperature sensor 27 and the liquid level sensor 28 on the partition plate 21.

[0037] The adaptive immersion mechanism also includes a four-ring electrode rod 26. There are multiple four-ring electrode rods 26 in a circular array on the top side of the inner wall of the processing box 1. An opening cover 3 is provided on the top side of the processing box 1. A conductivity transmitter 8 is provided on the middle and lower part of the side of the processing box 1 away from the feed pipe 2. A PLC display controller 7 is provided on the middle and upper part of the side of the processing box 1 away from the feed pipe 2.

[0038] At the same time, the rice soaked in the soaking water on the upper part of the mounting seat 24 is monitored in real time by the separation chamber 36 for the resistance data information in the soaking water. Due to the differences in rice varieties and soaking degrees, the resistivity monitored is also different. Then, the conductivity transmitter 8 on the processing box 1 converts the original resistance signal collected by its separation chamber 36 into a standard signal and transmits it to the PLC display controller 7 on the processing box 1. After receiving the conductivity, temperature and liquid level data information transmitted by it, the PLC display controller 7 uses a preset algorithm to calculate the conductivity value after temperature compensation, and compares it with the threshold value set by the staff to trigger a prompt light or sound effect, so that the staff will discharge the fully soaked rice into the collection device by opening the cover 3 for collection. At the same time, by soaking the rice, the starch remaining on the surface of the rice can be separated again in the soaking water, thereby completing the adaptive soaking treatment of different types of rice.

[0039] The degree of soaking of different rice varieties can be determined by their conductivity. The key lies in the correlation between the dissolution characteristics of substances during water absorption and the electrical signal. Due to the different cortical structures and composition of brown rice, polished rice, and glutinous rice, the amount of soluble substances such as minerals and amino acids dissolved during soaking varies. This results in a unique conductivity pattern in the soaking solution: brown rice, with its thick cortex and high mineral content, exhibits a rapid initial rise in conductivity and a high peak value; polished rice, which is primarily starch-based, has a more gradual rise in conductivity; and glutinous rice, with its high amylopectin content, has a smaller conductivity variation. When the rice grains near saturation, the dissolution of soluble substances essentially ceases, and the conductivity stabilizes, allowing a precise determination of the soaking endpoint.

[0040] This monitoring process requires the assistance of electrodes, combined with a pre-set conductivity threshold model in a rice variety database, to calibrate temperature effects in real time and dynamically adjust parameters. Compared to traditional timed soaking methods, this method avoids over- or under-soaking, precisely adapts to the characteristics of different rice varieties, and combines intelligence and versatility, providing a scientific and efficient solution for standardized pretreatment in rice processing.

[0041] Please see the attached Figure 8 , a cavitation separation mechanism is arranged on the other side of the processing box 1, and is used to perform final separation treatment on the rice in the process of being treated by the soaking mechanism and the starch on its surface.

[0042] The cavitation separation mechanism includes a mounting base 24, which is fixedly connected to the middle and lower part of one side of the interior of the processing box 1. The middle part of the top of the mounting base 24 is rotatably connected to the concave drive base 22. The top of the concave drive base 22 is provided with multiple stirring bases 37 in a circular array near the edge. An ultrasonic generator 25 is provided in the middle part of the top of the concave drive base 22, and a low-frequency driver 23 is provided in the middle part of the bottom end of the mounting base 24, and the output end of the low-frequency driver 23 is connected to the middle part of the concave drive base 22.

[0043] When the cavitation separation mechanism is started, while the adaptive soaking mechanism soaks the rice on the mounting seat 24, the low-frequency driver 23 at the bottom of the mounting seat 24 is started. When the low-frequency driver 23 is started, the concave driving seat 22 on the mounting seat 24 is driven to rotate at a low frequency. When the mounting seat 24 rotates, the stirring seat 37 thereon is also driven to rotate, so that the rice soaked on the upper part of the mounting seat 24 and the soaking water form a small vortex flow.

[0044] At the same time, the ultrasonic generator 25 on the concave driving seat 22 is started and generates ultrasonic waves. The vortex flow generated by the low-frequency rotation allows the rice grains to be evenly exposed to the ultrasonic waves. The ultrasonic waves generate cavitation bubbles in the water, and then the microjets generated when the bubbles burst impact the surface of the rice grains, thereby stripping the starch remaining on the surface of the rice grains, thereby completing the final stripping process of the starch attached to the rice surface.

[0045] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
