Description

Technical Field

[0001] This utility model relates to the technical field of rice washing devices, and in particular to a rice washing device for processing rice crusts. Background Technology

[0002] The processing of rice crust is a complex process with many important steps, each of which has a crucial impact on the quality and taste of the rice crust.

[0003] Rice washing: Wash the rice to ensure that the washing is even and thorough.

[0004] Rice cooking: After washing, the rice needs to be cooked to ensure it is fully cooked.

[0005] Tableting: Cooked rice needs to be pressed into thin sheets, which is usually done by a tablet press.

[0006] Seasoning: Seasoning is a key step in giving the rice crust a rich flavor.

[0007] Drying or frying: Drying or frying can give rice crusts a crispy texture.

[0008] Packaging and storage: Packaging not only protects the rice crust from external contamination and compression, but also has a significant impact on its shelf life and sales.

[0009] In the rice crust processing industry, rice is the main raw material, and its cleaning process is crucial. Traditional rice washing methods are mostly manual, which is not only labor-intensive and inefficient, but also makes it difficult to ensure uniform and thorough washing, easily leaving impurities that affect the final quality of the rice crust. Some simple mechanical washing devices are used, but their simple structural design and limited stirring function cannot fully and thoroughly stir and turn the rice, resulting in insufficient washing of rice near the container walls and bottom. Utility Model Content

[0010] Technical problems to be solved

[0011] To address the shortcomings of existing technologies, this utility model provides a rice washing device for rice crust processing, solving the crucial problem of rice washing being the primary raw material in the rice crust processing industry. Traditional rice washing methods are mostly manual, which is not only labor-intensive and inefficient, but also makes it difficult to ensure uniform and thorough washing, easily leaving impurities and affecting the final quality of the rice crust. Some simple mechanical washing devices have a limited structural design and limited stirring function, failing to fully and thoroughly stir and agitate the rice, resulting in insufficient washing of rice near the container walls and bottom.

[0012] Technical solution

[0013] To achieve the above objectives, this utility model provides the following technical solution:

[0014] A rice washing device for processing rice crust includes a washing tank, a stirring mechanism for stirring and washing rice inside the washing tank, a filtering mechanism at the side of the washing tank, a lid on the washing tank, a servo motor fixedly installed on the lid, a lifting platform at the bottom of the inner wall of the washing tank, two pull rods fixedly installed on the lifting platform, a stirring mechanism including a rotating shaft, a fixing ring fixedly installed at the lower end of the rotating shaft, four stirring rods fixedly installed on the fixing ring, a fixing block fixedly installed through the circumferential surface of the rotating shaft, and two flipping plates for turning and washing rice on the fixing block.

[0015] Preferably, the servo motor is fixedly connected to the rotating shaft via an output shaft, and the filtration mechanism includes a connecting water pipe, which is U-shaped, with its upper and lower ends respectively connected to the upper and lower ends of the cleaning tank.

[0016] Preferably, the lower end of the cleaning tank is provided with a filter box, the filter box is provided with activated carbon adsorbent, the filter box is provided with a cover plate, the side end of the filter box is provided with a filter screen, the filter screen is fixedly installed on the connecting water pipe, and the upper end of the connecting water pipe is provided with a water pump.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this new invention, a stirring mechanism (including a rotating shaft, a fixed ring, a stirring rod, a fixed block, and a flipping plate) is set up, and a servo motor drives the rotating shaft to drive the stirring rod and the flipping plate to work together. The stirring rod stirs the rice near the wall of the washing bucket, and the flipping plate turns over the rice at different levels, so that the rice is fully rolled and evenly washed in the water, effectively removing impurities, improving the cleanliness of the rice, providing high-quality raw materials for rice crust processing, and thus improving the taste and quality of the rice crust.

[0019] In this new invention, the cleaning water is recycled through a filtration mechanism (including connecting water pipes, a filter box, activated carbon adsorbent, a cover plate, a filter screen, and a water pump). The water pump draws the cleaning water from the cleaning tank, and through the U-shaped connecting water pipe, large particles of impurities are first intercepted by the filter screen, and then further purified by the activated carbon adsorbent in the filter box. The purified water flows back to the cleaning tank. This process not only saves a lot of water resources, but also reduces wastewater treatment costs and lowers the overall cost of rice crust production, which is in line with the concept of environmentally friendly production.

[0026] This application provides a rice washing device for rice crust processing, effectively solving the crucial problem of rice washing in the rice crust processing industry, where rice is the main raw material. Traditional rice washing methods are mostly manual, which is not only labor-intensive and inefficient, but also makes it difficult to ensure uniform and thorough washing, easily leaving impurities and affecting the final quality of the rice crust. Some simple mechanical washing devices have a simple structural design and limited stirring function, failing to fully and thoroughly stir and turn the rice, resulting in insufficient washing of rice near the container walls and bottom.

[0027] Example

[0028] like Figures 1-4 As shown, the technical solution in this application aims to effectively address the crucial role of rice washing in the rice crust processing industry, where rice is the primary raw material. Traditional rice washing methods are mostly manual, which is not only labor-intensive and inefficient but also fails to ensure uniform and thorough washing, easily leaving impurities and affecting the final quality of the rice crust. Some simple mechanical washing devices have limited structural design and stirring capabilities, failing to fully and adequately stir and agitate the rice, resulting in insufficient washing of rice near the container walls and bottom. The overall approach is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a rice washing device for rice crust processing, including a washing tank 21, which serves as the main container for washing rice, providing a relatively enclosed and suitable space for washing. The washing tank 21 is equipped with a stirring mechanism for stirring and washing the rice. This stirring mechanism allows the rice to fully tumble and rub in the water, effectively removing impurities and dust from the surface of the rice, improving the cleanliness of the rice, and providing high-quality raw materials for subsequent rice crust processing. A filter mechanism is provided on the side of the washing tank 21, which can filter the wastewater generated during the rice washing process. Purification effectively intercepts and removes impurities and dirt from the water, enabling the recycling of water resources. This saves water resources and reduces production costs. The washing tank 21 is equipped with a lid 22, which acts as a seal to prevent water from splashing out when stirring rice. It also reduces the entry of external dust and other impurities into the washing tank 21, ensuring a relatively clean washing environment. A servo motor 18 is fixedly installed on the lid 22. The servo motor 18 has precise speed control and stable power output, providing continuous, stable, and adjustable power to the stirring mechanism to ensure the consistency and reliability of the stirring effect.

[0030] The bottom of the inner wall of the washing tank 21 is equipped with a lifting platform 11. Two pull rods 12 are fixedly installed on the lifting platform 11. After washing, the lifting platform 11 can lift the washed rice to a suitable height by pulling the pull rods 12, making it convenient for operators to take out the rice, reducing labor intensity and improving the convenience of operation. The stirring mechanism includes a rotating shaft 17. A fixing ring 13 is fixedly installed at the lower end of the rotating shaft 17. Four stirring rods 14 are fixedly installed on the fixing ring 13. When the servo motor 18 drives the rotating shaft 17 to rotate, the stirring rods 14 rotate accordingly, which can fully stir the rice near the wall of the washing tank 21, avoid the rice from accumulating near the tank wall and not being washed thoroughly, and make the rice fully contact the water, thus improving the washing efficiency.

[0031] A fixing block 15 is fixedly installed through the circumference of the rotating shaft 17. The fixing block 15 is equipped with two flipping plates 16 for washing rice. During the rotation, the flipping plates 16 can flip the rice in different layers of the washing tank 21, making the rice more evenly distributed in the water, further enhancing the washing effect of the rice and ensuring that every grain of rice is thoroughly washed. The filtration mechanism includes a connecting water pipe 26. The connecting water pipe 26 is U-shaped. This design allows the water flow to form a certain buffer and backflow in the pipe, which helps impurities to settle and separate better under the action of gravity and water flow. The upper and lower ends of the connecting water pipe 26 are respectively connected to the upper and lower ends of the inside of the washing tank 21 to form a circulating water flow channel, which facilitates the recycling of washing water.

[0032] A filter box 23 is located at the lower end of the washing tank 21. The filter box 23 contains activated carbon adsorbent 25, which has a strong adsorption capacity and can effectively adsorb minute impurities, odors, and pigments in the water, further purifying the water quality, improving the cleanliness of the circulating water, and ensuring the washing quality of the rice. A cover plate 27 is provided on the filter box 23, facilitating the regular replacement and cleaning of the activated carbon adsorbent 25 inside the filter box 23, ensuring that the filtration effect of the filter box 23 remains at a good level. A filter screen 24 is located on the side of the filter box 23. The filter screen 24 is fixedly installed on the connecting water pipe 26. Its pore size is designed to be smaller than the grain size of rice, which can effectively prevent rice from entering the connecting water pipe 26, while allowing water containing impurities to pass through smoothly, ensuring the normal operation of the filtration process. A water pump 28 is provided at the upper end of the connecting water pipe 26. The water pump 28 provides power for the circulation of water, so that the water in the washing tank 21 can continuously pass through the filtration mechanism for purification, and then return to the washing tank 21 to continue to participate in the washing, forming a highly efficient circulating washing system, which greatly improves the washing efficiency and quality of rice.

[0033] Working principle:

[0034] Rice washing stage: When washing rice using this equipment, first remove the lid 22 along with the servo motor 18 and stirring mechanism mounted on it from the washing tank 21. Pour the rice to be washed into the washing tank 21 and add an appropriate amount of washing water. Then, close the lid 22 and start the servo motor 18. At this time, the output shaft of the servo motor 18 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the fixed ring 13 and the four stirring rods 14 fixed on the fixed ring 13 to rotate synchronously. The stirring rods 14 can stir the rice near the wall of the washing tank 21. Stirring allows the rice to come into full contact with and rub against the water, initially removing surface impurities. At the same time, as the rotating shaft 17 rotates, the two flipping plates 16 fixed on the fixing block 15 on the circumferential surface of the rotating shaft 17 also begin to rotate. Because the flipping plates 16 have a specific curvature, during their rotation, they will turn the rice in different layers of the washing tank 21 up and down. This turning action makes the rice more evenly distributed in the water, avoiding the situation where some rice is not cleaned sufficiently, effectively improving the rice cleaning efficiency, and ensuring that every grain of rice is thoroughly cleaned.

[0035] Impurity Filtration and Circulating Cleaning Stage: During the rice washing process, impurities and white powder from the rice are generated. At this time, the water pump 28 is activated, generating suction to draw the cleaning water from the cleaning tank 21. When the water flows through the connecting water pipe 26, it passes through the filter screen 24 fixedly installed on the connecting water pipe 26. The pore size of the filter screen 24 is designed to be smaller than the particle size of the rice, which can effectively block the rice and prevent it from being drawn away, while allowing some fine impurities and white powder from the rice to pass through the filter screen 24 and enter the connecting water pipe 26. Subsequently, this water containing impurities flows into the filter box 23 at the bottom of the cleaning tank 21. The activated carbon adsorbent 25 filled in the filter box 23 plays a role in adsorbing and filtering the impurities and white powder in the water, further purifying the water quality. After purification, the water returns to the cleaning tank 21 under the action of the water pump 28 to continue to participate in the washing of rice, forming a circulating cleaning process and continuously improving the cleaning effect.

[0036] Rice Removal Stage: After the rice is washed, first remove the lid 22 and stirring mechanism from the washing tank 21. Then, pull up the two levers 12 fixedly installed on the lifting platform 11. The levers 12 drive the lifting platform 11 to move upward, so that the washed rice at the top of the lifting platform 11 rises to a position that is easy to remove, making it convenient for the operator to remove the washed rice from the washing tank 21, thus completing the entire rice washing process.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
