Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a rice washing and drying device. Background Technology

[0002] Currently, rice is usually washed and spun dry before cooking. This is typically done by placing the rice in a rice washing basket, rinsing it, and then manually shaking the basket to dry it. However, due to the widespread use of smart technology and the need to wash and dry large quantities of rice in industrial production, existing rice washing and drying devices struggle to ensure sufficient contact between water and rice during washing, making it difficult to dry the rice quickly. Further improvements are needed.

[0003] Chinese patent document CN218797741U discloses a rice washing and drying device, which consists of a carrier and a washing tank fixedly installed on the upper end of the carrier.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-6 As shown, a rice washing and drying device includes a separation box 1, a washing component 4 is fixedly installed at the upper end of the separation box 1, a uniform drying component 3 is fixedly installed at the bottom right side of the separation box 1, and a separation component 2 is movably connected to the middle of the inner wall of the separation box 1.

[0029] The separation assembly 2 includes a screening filter plate 21. The left part of the screening filter plate 21 is rotatably connected to the left part of the inner wall of the separation box 1. A discharge chute 22 is provided at the bottom right side of the separation box 1. The screening filter plate 21 is inclined and its right part extends out of the separation box 1 from the discharge chute 22. A rotating shaft 23 is rotatably connected to the bottom front side of the separation box 1, penetrating the front of the separation box 1. A cam 24 is fixedly sleeved in the middle of the outer wall of the rotating shaft 23. The outer surface of the cam 24 abuts against the lower end of the screening filter plate 21. A motor 25 is fixedly installed at the bottom front side of the separation box 1. The output end of the motor 25 is fixedly connected to the front end of the rotating shaft 23. Guide seats 26 are fixedly installed at the left and right positions of the bottom inner wall of the separation box 1. Several water outlet pipes 27 arranged linearly and with valves installed inside are installed through the middle of the lower end of the separation box 1. Several water outlet pipes 27 are located between two guide seats 26.

[0030] The uniform drying component 3 includes a mounting frame 31 with open sides. The left side of the mounting frame 31 is fixedly installed at the bottom right side of the separation box 1. The mounting frame 31 is connected to the discharge chute 22. An electric conveyor belt 32 is movably connected to the bottom of the left and right sides of the inner wall of the mounting frame 31. The electric conveyor belt 32 is located below the screening filter plate 21. The outer circumference of the electric conveyor belt 32 has a porous structure. A rotating rod 33 is rotatably connected to the left side of the front of the mounting frame 31, penetrating the front of the mounting frame 31. Several dispersing rods 34 are fixedly installed on the rear of the outer wall of the rotating rod 33 in a linear arrangement. Several dispersing rods 34 are located above the electric conveyor belt 32. A linkage mechanism is movably connected to the front of the outer wall of the rotating shaft 23 and the rotating rod 33. A drying mechanism penetrating the top of the mounting frame 31 is fixedly connected to the middle of the upper end of the mounting frame 31.

[0031] After washing, the rice is separated from the wastewater by the separation component 2. The separated rice falls from the discharge chute 22 onto the electric conveyor belt 32 through the vibrating screening filter plate 21. This process not only effectively removes moisture from the surface of the rice but also prevents impurities in the wastewater from further contaminating the rice, making it highly practical. The uniform drying component 3 disperses and pushes the rice that has fallen onto the electric conveyor belt 32. The linkage mechanism transmits the rotational power of the motor 25 to the rotating rod 33, so that when the device vibrates and drains the rice, several dispersing rods 34 can also separate the accumulated rice grains, which helps to quickly dry the rice and improves the efficiency of the washing and drying process.

[0032] like Figure 4 and Figure 5 As shown, a fixing plate 28 is fixedly installed at the front and rear positions of the left side of the inner wall of the mounting frame 31. The upper end of the fixing plate 28 is flush with the bottom of the inner wall of the discharge trough 22. Several springs 29 arranged in a linear pattern are fixedly installed on the upper end of the fixing plate 28. The upper ends of the springs 29 are fixedly connected to the lower right side of the screening filter plate 21.

[0033] When the rotating shaft 23 drives the cam 24 to rotate, the cam 24 will continuously press the bottom of the screening filter plate 21. During this process, the spring 29 will extend and retract due to the force, and the screening filter plate 21 will vibrate up and down. This not only allows the rice to be separated from the sewage quickly, but also bounces off the water on the surface of the rice.

[0034] like Figure 6 As shown, the linkage mechanism includes two pulleys 35. The inner walls of the two pulleys 35 are fixedly connected to the front of the outer walls of the rotating shaft 23 and the rotating rod 33, respectively. The outer surfaces of the two pulleys 35 are connected to a belt 36 for transmission.

[0035] The belt 36 and two pulleys 35 can transmit the rotational power of the motor 25 to the rotating rod 33, so that when the screening filter plate 21 vibrates, the several dispersing rods 34 can also disperse the rice.

[0036] like Figure 3 and Figure 6 As shown, the drying mechanism includes a suction heating structure 37 and an air conveying pipe 38. The lower end of the suction heating structure 37 is fixedly connected to the middle of the upper end of the mounting frame 31. The left and right ends of the air conveying pipe 38 are fixedly connected to the left and right positions of the top of the inner wall of the mounting frame 31. The output end of the suction heating structure 37 is connected to the air conveying pipe 38. Several nozzles 39 arranged in a linear pattern are fixedly installed on the bottom of the outer wall of the air conveying pipe 38.

[0037] The suction heating structure 37 is existing technology. It mainly draws in outside air, filters it, heats it into hot air through its internal components, blows it into the air supply pipe 38, and finally acts on the surface of the rice by several nozzles 39.

[0038] like Figure 3 As shown, a through groove is provided at the bottom front side of the mounting frame 31, and a water receiving box 310 is slidably connected to the bottom inner wall of the mounting frame 31. The water receiving box 310 is located directly behind the through groove.

[0039] When rice falls onto the electric conveyor belt 32, the residual moisture on its surface will be transferred into the water collection box 310 by the electric conveyor belt 32. During subsequent cleaning, it can be slid forward from the channel and pulled out.

[0040] like Figure 3 and Figure 4 As shown, the cleaning assembly 4 includes a cleaning tank 41. Three mounting brackets arranged in a ring are fixedly installed on the outer wall of the cleaning tank 41. The lower ends of the three mounting brackets are fixedly installed at the upper edge of the separation box 1. A discharge pipe 42 penetrating the top of the separation box 1 is fixedly installed at the lower end of the cleaning tank 41. An electric valve 43 is fixedly installed at the top of the inner cavity of the discharge pipe 42. A feed hopper 44 is fixedly installed on the upper left side of the cleaning tank 41.

[0041] External pumps pump water into the washing tank 41 through the inlet pipe 45. An appropriate amount of rice is added to the washing tank through the feed hopper 44. The stirring structure 46 agitates the rice, ensuring it is evenly mixed with the water. After the rice is washed, the electric valve 43 is opened, discharging the wastewater and rice from the discharge pipe 42 into the separation box 1.

[0042] like Figure 4 As shown, a water inlet pipe 45 is fixedly installed on the upper right side of the cleaning tank 41, and a stirring structure 46 is movably connected to the middle of the inner cavity of the cleaning tank 41.

[0043] The stirring structure 46 is an existing structure, which includes a drive motor, a connecting rod and several stirring rods. The drive motor is fixedly installed in the middle of the upper end of the cleaning tank 41, and its output end is fixedly connected to the upper end of the connecting rod. The connecting rod passes through the top of the cleaning tank 41, and several stirring rods are distributed on the outer wall of the connecting rod.

[0044] The working principle of this utility model is as follows: When in use, external water is pumped into the cleaning tank 41 through the water inlet pipe 45 by the external pump body, and an appropriate amount of rice is added into the cleaning tank through the feed hopper 44. The stirring structure 46 can stir the rice so that the rice and water are mixed evenly. After the rice is washed, the electric valve 43 is opened to discharge the wastewater and rice from the discharge pipe 42 into the separation box 1. The motor 25, the electric conveyor belt 32, and the drying mechanism start simultaneously. The output end of the motor 25 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the cam 24 to rotate. The cam 24 will continuously press the bottom of the screening filter plate 21. During this process, the spring 29 will extend and retract due to the force. The screening filter plate 21 vibrates up and down, which not only separates the rice from the wastewater quickly, but also bounces off the water on the surface of the rice. The separated rice falls from the discharge chute 22 onto the electric conveyor belt 32 along the inclined screening filter plate 21. The electric conveyor belt 32 continuously conveys the rice on it to the right, while the water remaining on the rice falls from the porous surface of the electric conveyor belt 32 into the water collection box 310.

[0045] Meanwhile, the left pulley 35 drives the right pulley 35 to rotate via the belt 36, which transmits the rotational power of the motor 25 to the rotating rod 33. When the screening filter plate 21 vibrates, the several dispersing rods 34 can also disperse the rice on the surface of the electric conveyor belt 32, improving drying efficiency. The suction heating structure 37 is existing technology, which mainly draws in outside air, filters it, heats it into hot air through its internal components, blows it into the air supply pipe 38, and finally acts on the surface of the rice by several nozzles 39.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
