Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to a rice processing and cleaning device. Background Technology
[0002] Rice is one of the world's most important food crops, widely grown in many countries around the world, especially in Asia. As a staple food, rice directly affects the livelihoods and health of billions of people globally. In modern agricultural production, the quality requirements for rice are becoming increasingly stringent, and consumers have increasingly strict demands regarding the taste, nutritional components, and hygiene and safety of rice. Therefore, how to improve rice processing efficiency, ensure its quality, and reduce potential pollution during processing has become a crucial issue that the rice processing industry urgently needs to address.
[0003] In traditional rice production, rice undergoes multiple processes, including hulling, milling, washing, threshing, and refining. Each process significantly impacts the quality of the rice, especially the washing process. Washing is an indispensable step in rice processing; its main purpose is to remove dust, impurities, pesticide residues, and other contaminants that may affect the quality of the rice, thus ensuring its hygiene, safety, and taste before it leaves the factory.
[0004] However, traditional rice washing processes have some drawbacks, mainly in the following aspects:
[0005] Inadequate cleaning results: Traditional cleaning methods typically rely on manual labor or simple mechanical equipment, which are inefficient at removing impurities and dust from the surface of rice. In particular, rice is easily affected by water quality, temperature, and time during the cleaning process, leading to incomplete cleaning and potentially leaving impurities on the surface of the rice grains, affecting its taste and safety.
[0006] Water waste is severe: The rice washing process typically requires a large amount of water, especially when the washing facilities are poorly designed or the water circulation system is inadequate, leading to significant water waste. This not only increases production costs but also places a burden on the environment.
[0007] The treatment of pollutants is difficult: Wastewater generated during rice washing may contain pesticide residues, microorganisms, and other pollutants. If this wastewater is discharged into the environment without effective treatment, it will pollute water resources and affect the ecological environment.
[0008] Low processing efficiency: Traditional washing equipment is usually quite simple and cannot complete the rice washing process efficiently and at low cost. During busy seasons, production lines often cannot meet the needs of large-scale production, resulting in low rice processing efficiency and difficulty in increasing production capacity.
[0009] To address these issues, in recent years, with continuous technological advancements, an increasing number of new cleaning equipment and technologies have been introduced into the rice processing industry. These new devices not only improve the efficiency of rice washing but also address issues such as water resource utilization and pollutant treatment, providing rice processing enterprises with a more sustainable production method.
[0010] Currently, some rice washing equipment both domestically and internationally has undergone technological innovation. Many advanced rice washing machines employ new cleaning technologies such as high-pressure water jets, airflow rinsing, and ultrasonic waves, which can more efficiently and thoroughly remove impurities and contaminants from the surface of rice. In addition, some machines also use intelligent control systems that can automatically adjust the washing time, water volume, and other cleaning parameters according to the different types of rice, impurity content, and washing requirements, greatly improving processing efficiency and automation.
[0011] For example, some rice washing machines employ multi-stage filtration and sorting technology. Through step-by-step washing and sieving, they can effectively remove most impurities from the surface of the rice, while using airflow or vibration to remove dust and fine impurities adhering to the rice grains. This washing method not only improves the washing effect but also significantly reduces water consumption, saving resources.
[0012] In addition, some rice washing equipment uses intelligent water recycling systems, which recycle and reuse the water used in the washing process after simple treatment, thus avoiding water waste. This design not only meets modern energy-saving and environmental protection requirements but also reduces production costs in the rice washing process.
[0013] However, despite the existence of some advanced rice washing equipment, existing technology still has certain limitations. In particular, in current rice processing and washing devices, washed rice typically needs to pass through a filter to separate residual impurities. However, these filters are often not designed for easy disassembly, making cleaning them very difficult or impossible. This not only increases maintenance difficulty but may also affect the normal operation and lifespan of the washing device. Furthermore, there is usually no specific cleaning step before washing the rice to remove the bran and light impurities from the rice surface. Simply rinsing with water may not completely remove all impurities, especially fine particles adhering to the rice surface. This means that these impurities may not be effectively removed during subsequent washing processes, affecting the final cleanliness and quality of the rice. Summary of the Invention

For example, the filter chamber is securely fixed to the chassis through locking components and plug-in design, while also allowing for easy disassembly and cleaning, increasing the maintainability and ease of use of the device.
[0029] Segmented processing and efficient coordination: The cleaning tank and the washing tank are connected by a connecting pipe. The transfer of cleaned rice is completed automatically, ensuring seamless connection between each stage and improving the overall working efficiency of the system.
[0030] The proposed solution, through meticulous design, achieves multiple functions including cleaning, filtration, and dust extraction, making rice processing more efficient, cleaner, and automated. This avoids manual cleaning and environmental pollution, and improves the production efficiency and product quality of rice processing plants.
[0031] This utility model has the following beneficial effects:
[0032] Rice processing and cleaning is a crucial step in rice production, directly impacting the final rice's quality and market competitiveness. Traditional rice cleaning methods rely heavily on manual labor or inefficient machinery, resulting in low efficiency and inconsistent cleaning effectiveness. The solution presented in this application significantly improves cleaning efficiency through a multi-stage cleaning, filtration, and dust extraction system. First, by employing a multi-stage cleaning process, the agitator within the cleaning tank, driven by a primary motor, efficiently stirs and cleans the rice, removing surface impurities such as dust and bran. This multi-stage cleaning design ensures more thorough processing of the rice, thereby enhancing its cleanliness and quality. Compared to traditional single-stage cleaning methods, this multi-stage cleaning more comprehensively removes surface contaminants from the rice, ensuring it meets higher hygiene standards.
[0033] Improving the quality and purity of rice is crucial, as rice quality is paramount for consumers, especially impurities such as stones and dirt, which directly impact food safety. The device described in this application utilizes a sophisticated multi-stage filtration system to ensure thorough removal of impurities from the rice. The filter chamber securely fastens the chassis to the filter screen using a locking assembly, effectively preventing larger impurities (such as stones and sand) from entering the rice product. Simultaneously, the device's dust collection system draws finer impurities like rice bran and dust into a collection box through a guide pipe, preventing them from re-entering the washed rice. Waste such as rice bran is collected and processed, further enhancing the purity of the rice.
[0034] Optimizing automated operations and reducing human intervention: Traditional rice washing processes often require significant manual labor, such as observation, handling, and cleaning impurities. This manual intervention not only increases labor intensity but can also lead to inconsistent washing results due to human error. This design, through an automated workflow, greatly reduces manual intervention and improves production efficiency. The washing and filtration system can automatically complete the entire washing, filtration, and vacuuming process according to set parameters. Workers only need to perform minimal operations, such as adjusting settings and monitoring equipment operation, thereby reducing labor costs and lowering the probability of human error. This automated design not only improves work efficiency but also enhances the controllability and stability of the production process.
[0035] To reduce labor costs and improve production efficiency, more and more industries are seeking automated production equipment to lower labor costs as labor costs rise. This rice washing device is designed to meet this need perfectly. The automated system can replace a significant amount of manual labor, saving on labor costs; by reducing human intervention, companies can reduce the cost pressure caused by manual operation, while also improving the operating efficiency of the production line. Because the washing process is automated, the efficient operation of the equipment ensures the speed and quality of rice washing, significantly improving the overall production efficiency of the production line. The equipment can work 24 hours a day without interruption, greatly increasing the output and profit margins of rice processing plants.
[0036] Optimizing the working environment and reducing air pollution is crucial. During rice washing, waste such as rice bran and dust generates significant air pollution. Without an effective dust collection system, these pollutants permeate the workshop, degrading air quality and impacting worker health. The dust collection system in this application effectively solves this problem. The device's second motor drives a cleaning brush, drawing rice bran and dust into a collection box through a suction pipe, thus preventing dust from spreading through the air. This closed-loop collection system effectively collects and treats rice bran and dust, reducing air pollution in the workshop and optimizing the working environment. This not only improves the hygiene of the production environment but also reduces occupational diseases caused by dust inhalation, protecting worker health.
[0037] To reduce resource waste and improve material utilization, traditional rice washing processes often involve a certain degree of resource waste, such as wasted washing water and improper handling of byproducts like rice bran. This design effectively avoids this waste by centrally collecting and processing waste such as rice bran and dust. First, after being sucked into the collection bin, the rice bran and dust can be centrally disposed of, preventing them from being discarded arbitrarily and wasting recyclable resources. Furthermore, with this centralized processing method, byproducts like rice bran can be further processed and utilized, such as in animal feed production, thereby improving resource utilization.
[0038] Improving the maintainability and lifespan of equipment is crucial for ensuring its long-term stable operation. Traditional rice washing equipment often presents inconveniences during cleaning and maintenance, making it prone to malfunctions and damage. The solution proposed in this application optimizes the equipment's structure, making it easier to maintain and clean. The filter chamber, through its locking components and plug-in design, allows for convenient disassembly and cleaning. Workers can quickly replace or clean the filter screen without cumbersome operations, reducing equipment maintenance time and costs. Simultaneously, the equipment design also considers reliability during long-term operation, reducing the failure rate and extending the equipment's lifespan.
[0039] Driving technological upgrades in the industry, the traditional rice processing industry is facing pressure to transform and upgrade as intelligent manufacturing and automation technologies continue to develop. The rice washing device design proposed in this application adopts advanced automation and environmental protection technologies, providing a model for technological upgrading in the industry. By introducing such technologies, the entire rice processing industry can be improved in terms of equipment intelligence, washing efficiency, and environmental protection.
[0040] The rice processing and washing device design proposed in this application demonstrates significant benefits in improving production efficiency, ensuring rice quality, optimizing the working environment, reducing labor costs, and minimizing resource waste. It not only enhances the automation and efficiency of rice processing but also lowers production costs and improves market competitiveness for enterprises. The considerations for environmental protection and worker health also reflect the forward-thinking nature and social responsibility of this design. Attached Figure Description

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0049] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a rice processing and cleaning device, comprising a base 1, a cleaning tank 2 fixedly connected to the inner wall of the base 1, a water valve 12 fixedly connected to the bottom end of the cleaning tank 2, a base plate 13 fixedly connected to the bottom end of the water valve 12, a filter chamber 14 clamped at the bottom end of the base plate 13, a locking assembly provided on the inner wall of the filter chamber 14, the filter chamber 14 fixing the base plate 13 relative to the filter plate 13 by the locking assembly, the locking assembly including a lower pressure plate 16 slidably connected to the front and rear sides of the inner wall of the filter chamber 14, a compression spring 23 fixedly connected to the bottom end of the lower pressure plate 16, a placement block fixedly connected to the inner wall of the compression spring 23, and an insert 20 fixedly connected to the top end of the lower pressure plate 16, the insert 20 being used for... The bottom of the chassis 13 is inserted into the bottom of the chassis 13. The bottom of the chassis 13 is fixedly connected to the locking piece 18. The inner wall of the locking piece 18 is provided with a slot 21. The size of the slot 21 is adapted to the plug-in 20. The top of the inner wall of the filter chamber 14 is fixedly connected to the locking ring 19. The locking piece 18 is used to lock into the locking ring 19. The filter chamber 14 is provided with a first filter screen. The filter screen is used to block stones or sand. The top of the washing tank 2 is fixedly connected to the first motor 4. The drive end of the first motor 4 passes through the washing tank 2 and is fixedly connected to the agitator 15. The agitator 15 is used to wash rice. The right side of the top of the washing tank 2 is fixedly connected to the first feed port 17. The outer wall of the first feed port 17 is threadedly connected to the cap 3.
[0050] Specifically, the operator opens the cover 3 on the first feed inlet 17 and adds an appropriate amount of clean water into the washing tank 2 through the first feed inlet 17. At this time, the first motor 4 is started, causing the first motor 4 to drive the agitator 15 to rotate, thoroughly washing the rice. The agitator 15 is scientifically designed; its blade angle and rotation speed are carefully calculated to fully agitate the rice, ensuring thorough contact between the rice and water, thereby effectively washing away any stones or grit on the rice. After washing is complete, the operator turns off the first motor 4 and removes the container. After aligning the container with the bottom of the filter chamber 14, open the water valve 12 to allow rice and clean water to flow out from the first filter screen in the filter chamber 14. The first filter screen can effectively block impurities such as stones or sand. After use, press down on the pressure plate 16 to compress the pressure spring 23, causing the pressure plate 16 to pull the insert 20 downwards, so that the insert 20 leaves the slot 21. Then, rotate the filter chamber 14 to disengage the locking ring 19 on the filter chamber 14 from the locking piece 18. Then, the first filter screen in the filter chamber 14 can be cleaned or replaced.
[0051] Reference Figure 1 and Figure 5 A support frame 9 is fixedly connected to the top of the base 1. A cleaning tank 10 is fixedly connected to the inner wall of the support frame 9. A second feed inlet is provided at the top of the cleaning tank 10 for feeding rice. A second motor 11 is fixedly connected to the left end of the cleaning tank 10. The drive end of the second motor 11 passes through the cleaning tank 10 and is fixedly connected to a cleaning brush 22. A guide tube 7 is located at the right end of the cleaning brush 22. A collection box 5 is fixedly connected to the bottom end of the guide tube 7. The bottom end of the collection box 5 is fixedly connected to the washing tank 2. At the top, a blower 6 is fixedly connected to the top of the collection box 5. A second filter screen is provided at the bottom of the blower 6 to prevent dust or rice bran from entering the blower 6. A collection box is provided at the front of the collection box 5. A guide pipe 7 is used to suck the dust and rice bran in the cleaning tank 10 into the collection box 5. A connecting pipe 8 is fixedly connected to the left end of the washing tank 2. The top end of the connecting pipe 8 is fixedly connected to the bottom end of the cleaning tank 10. The connecting pipe 8 is used to pass the cleaned rice in the cleaning tank 10 into the washing tank 2.
[0052] Specifically, rice is fed into the cleaning tank 10 through the second inlet. The operator must ensure that the second inlet is fully open so that the rice flows smoothly into the cleaning tank 10. Then, the second motor 11 is started, which drives the cleaning brush 22 to rotate through its drive end, performing a preliminary cleaning of the rice. The bristles of the cleaning brush 22 are soft and dense, effectively sweeping off the dust and rice bran on the surface of the rice, ensuring that most of the surface impurities have been removed before the rice enters the washing stage. At the same time, the exhaust fan 6 is started, which sucks the dust and rice bran in the cleaning tank 10 into the collection box 5 through the guide pipe 7. The guide pipe 7 ensures that the dust and rice bran can enter the collection box 5 smoothly without overflowing. Then, the second filter screen effectively blocks dust or rice bran from entering the exhaust fan 6, preventing the exhaust fan 6 from being damaged by the accumulation of impurities and extending the service life of the equipment. After cleaning is completed, the rice falls into the washing tank 2 through the connecting pipe 8, ensuring that the rice can be transferred smoothly.
[0053] Working principle: Rice is fed into the cleaning tank 10 through the second feed inlet. Then, the second motor 11 is started, which drives the cleaning brush 22 to perform preliminary cleaning of the rice, sweeping off the dust and rice bran on the surface of the rice. At the same time, the exhaust fan 6 starts working, sucking the dust and rice bran in the cleaning tank 10 into the collection box 5 through the guide pipe 7. After being filtered by the second filter screen, dust or rice bran is prevented from entering the exhaust fan 6. After cleaning is completed, the rice falls into the washing tank 2 through the connecting pipe 8.
[0054] Next, open the cover 3 on the first feed inlet 17 and add an appropriate amount of water into the washing tank 2 through the first feed inlet 17. Then, start the first motor 4, which drives the agitator 15 to wash the rice. During the washing process, the rotation of the agitator 15 can fully agitate the rice, ensuring that the rice and water are in full contact. After washing, turn off the first motor 4 and open the water valve 12 to allow the rice and clean water to flow out from the first filter screen in the filter chamber 14. After use, press down on the lower pressure plate 16 to compress the spring 23, causing the lower pressure plate 16 to pull the insert 20 downwards, disengaging the insert 20 from the slot 21. Then, rotate the filter chamber 14 to disengage the retaining ring 19 from the retainer 18, and then clean the stones or sand and other impurities on the first filter screen in the filter chamber 14.
[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
