Technical Field
[0001] This utility model belongs to the field of rice grain soaking technology in rice noodle production, and specifically relates to a rice grain soaking device for rice noodle production. Background Technology
[0002] Rice noodles are a highly representative specialty snack in southern China. Made from rice, they are processed through soaking, steaming, and pressing to create strips or strands. They are soft, chewy, and elastic, not becoming mushy when boiled or easily breaking when stir-fried. Served with various toppings or broths, they are smooth, flavorful, and beloved by consumers. In rice noodle production, soaking the rice grains is one of the key steps affecting the quality of the finished product. Choosing the right rice variety is crucial; moderately sticky varieties, such as glutinous rice or some indica rice, are typically selected. These varieties contain appropriate amounts of amylose and amylopectin, which help improve the elasticity and texture of the rice noodles. The cleaned rice is placed in a container with enough water, and the soaking time depends on the type of rice and the ambient temperature, generally 6-12 hours, allowing the rice grains to fully absorb water and expand, facilitating subsequent grinding. Scientific soaking can improve the water absorption rate of rice grains, enhance processing performance, and ultimately affect the taste, elasticity, and transparency of rice noodles. It allows rice grains to absorb water to the optimal moisture content (usually 30%-35%), which facilitates subsequent grinding and shaping. It can also reduce the hardness of rice grains and reduce mechanical wear during grinding.
[0003] Currently, in the process of using existing rice grain soaking devices for rice noodle production, rice grains are usually poured directly into a mesh frame and then soaked in a soaking tank. However, during the soaking process, the water inside the traditional rice grain soaking device is often stagnant, and the water flow is poor. This may result in large differences in the degree of water absorption by different parts of the rice grains, causing some rice grains to be too soft (the outer layer absorbs more water) and some rice grains to be too hard (the inside does not absorb enough water), thereby reducing the soaking effect of the rice grains. Utility Model Content
[0004] The purpose of this utility model is to provide a rice grain soaking device for rice noodle production, aiming to solve the problem that in the existing rice grain soaking devices for rice noodle production, rice grains are usually poured directly into a mesh frame and then soaked in a soaking tank. However, during the soaking process, the water inside the traditional rice grain soaking device is often in a stagnant state, and the water has poor flow. Therefore, the degree of water absorption of different parts of the rice grain may vary greatly, resulting in some rice grains being too soft (the outer layer absorbs more water) and some rice grains being too hard (the inside does not absorb enough water), thus reducing the soaking effect of the rice grains.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice grain soaking device for rice noodle production, comprising a soaking tank, a soaking trough on the top of the soaking tank, three soaking frames on the inner side of the soaking trough, a base connected to the bottom of the soaking tank, and a drain pipe connected to one side of the soaking tank;
[0006] The bottom of the soaking tank is connected to a first connecting plate and a second connecting plate. Three first rotating rods pass through the bottom of the soaking tank. A stirring paddle is installed at one end of each of the three first rotating rods. A first conical tooth is connected to the end of each of the three first rotating rods away from the stirring paddle. A motor is installed on one side of the first connecting plate. The output end of the motor is connected to a second rotating rod with three second conical teeth.
[0007] As a preferred embodiment of the rice grain soaking device for rice noodle production according to this utility model, the device has three stirring paddles, and the three stirring paddles are distributed at equal intervals.
[0008] In a preferred embodiment of the rice grain soaking device for rice noodle production according to this utility model, the end of the second rotating rod away from the motor is connected to the second connecting plate through a bearing to form a rotating connection structure.
[0009] In a preferred embodiment of the rice grain soaking device for rice noodle production according to this utility model, the three second conical teeth respectively mesh with one first conical tooth.
[0010] As a preferred embodiment of the rice grain soaking device for rice noodle production according to this utility model, the top of the soaking tank is provided with six positioning slots, and the six positioning slots are arranged in pairs opposite each other.
[0011] As a preferred embodiment of the rice grain soaking device for rice noodle production according to this utility model, the outer walls of the three soaking frames are connected to a hanging frame, the hanging frame has an L-shaped cross-section, and a handle is installed on the top of the hanging frame.
[0012] As a preferred embodiment of the rice grain soaking device for rice noodle production according to this utility model, the end of the hanging frame away from the soaking frame is adapted to the size of the positioning groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The motor drives the second rotating rod to rotate, and then the meshing relationship between the three second bevel teeth and the first bevel teeth drives the three first rotating rods to rotate at the same time. At this time, the stirring paddles at one end of the three first rotating rods will stir the water in the soaking tank, thereby enhancing the fluidity of the water in the soaking tank and allowing the rice grains in different parts to be soaked more effectively.
[0015] By incorporating positioning slots, hanging racks, and handles, the soaking frames are positioned by inserting one end of the hanging rack into a positioning slot when placed in the soaking tank. This improves the stability of the soaking frames and allows for a certain distance between them, enabling better water flow. This prevents the water from forming "dead corners" between the frames due to insufficient spacing, which would hinder the full contact between rice grains and water in rice noodle production.

[0022] 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.
[0023] Please see Figures 1-4 The present invention provides the following technical solution: a rice grain soaking device for rice noodle production, including a soaking tank 1, a soaking tank 2 opened on the top of the soaking tank 1, three soaking frames 3 arranged on the inner side of the soaking tank 2, a base 4 connected to the bottom of the soaking tank 1, and a drain pipe 5 connected to one side of the soaking tank 1.
[0024] The bottom of the soaking tank 1 is connected to a first connecting plate 6 and a second connecting plate 7. Three first rotating rods 8 pass through the bottom of the soaking tank 1. A stirring paddle 9 is installed at one end of the three first rotating rods 8. A first conical tooth 10 is connected to the end of the three first rotating rods 8 away from the stirring paddle 9. A motor 11 is installed on one side of the first connecting plate 6. A second rotating rod 12 is connected to the output end of the motor 11. The second rotating rod 12 has three second conical teeth 13.
[0025] It should be noted that a ball valve is installed at one end of the drain pipe 5. The water in the soaking tank 2 can be discharged by opening and closing the ball valve. The first connecting plate 6 and the second connecting plate 7 are symmetrically distributed. The end of the drain pipe 5 can be connected to an external water storage container through a water pipe. The water used for soaking rice can be filtered and recycled after passing through the filtration device.
[0026] Preferably, there are three stirring paddles 9, and the three stirring paddles 9 are distributed at equal intervals. The end of the second rotating rod 12 away from the motor 11 is connected to the second connecting plate 7 through a bearing to form a rotating connection structure. The three second bevel teeth 13 are respectively engaged with one first bevel tooth 10.
[0027] In practical use, the motor 11 drives the second rotating rod 12 to rotate, and then the meshing relationship between the three second bevel teeth 13 and the first bevel teeth 10 is used to drive the three first rotating rods 8 to rotate at the same time. At this time, the stirring paddle 9 at one end of the three first rotating rods 8 will stir the water in the soaking tank 2, thereby enhancing the fluidity of the water in the soaking tank 2, so that the rice grains for rice flour production in different parts can be soaked more effectively.
[0028] It should be noted that the motor 11 is connected to an external power supply and control switch, and the speed of the motor 11 is controlled between 500-1000 r / min to ensure that the rice grains fully absorb water and maintain structural integrity.
[0029] Preferably, the top of the soaking tank 1 is provided with six positioning slots 14, and the two positioning slots 14 are opposite each other in pairs. The outer walls of the three soaking frames 3 are connected to the hangers 15. The hangers 15 have an L-shaped cross section and a handle 16 is installed on the top of the hangers 15. The end of the hangers 15 away from the soaking frames 3 is adapted to the size of the positioning slots 14.
[0030] In practical use, through the setting of positioning groove 14, hanging bracket 15 and handle 16, when the soaking frame 3 is placed in the soaking tank 2, the positioning function can be achieved by inserting one end of the hanging bracket 15 on the soaking frame 3 into a positioning groove 14, which improves the stability of the soaking frame 3 when it is placed, and can maintain a certain distance between each soaking frame 3, so that the water between the soaking frames 3 can flow better, thereby avoiding the situation where the water flow forms a "dead corner" between the frames due to the small distance between the soaking frames 3, which would hinder the full contact between the rice grains and water used for rice noodle production.
[0031] It should be noted that by pulling the soaking frame 3 upward by using the handle 16 on the top of the hanger 15, the insertion end of the hanger 15 can be pulled out from the positioning groove 14, thereby removing the soaking frame 3 from the soaking tank 2.
[0032] Working principle: First, water is added to the soaking tank 2 via a water pipe. Then, through the positioning slots 14, the hanging brackets 15, and the handles 16, when the soaking frames 3 are placed in the soaking tank 2, inserting one end of each hanging bracket 15 into a positioning slot 14 provides positioning, improving the stability of the soaking frames 3 and maintaining a certain distance between them. This allows for better water flow between the frames, preventing the formation of "dead corners" between the frames due to insufficient spacing, which would hinder the rice grains from fully absorbing water. In the case of partial contact, the rice grains required for rice noodle production are poured into a soaking frame 3, and the water level in the soaking tank 2 should be 5-8 cm higher than the surface of the rice grains. During the soaking process, the motor 11 drives the second rotating rod 12 to rotate, and then the meshing relationship between the three second conical teeth 13 and the first conical teeth 10 drives the three first rotating rods 8 to rotate. At this time, the stirring paddles 9 at one end of the three first rotating rods 8 will stir the water in the soaking tank 2, thereby enhancing the fluidity of the water in the soaking tank 2, so that the rice grains in different parts can be soaked more effectively.
[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
