Beneficial effects: This utility model employs a weighing sensor and a discharge bin. During compound nutrient rice mixing, rice flour containing different nutrients can be placed into the ingredient mixing tank. A servo motor drives a shaft to rotate, which in turn drives an auger to add the rice flour into the mixing tank.

Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, to a multifunctional compound nutrient rice ingredient mixing device. Background Technology

[0002] Compound rice is an artificial rice made by grinding different types of rice containing various nutrients, mixing them together, and then re-extruding them into a new shape. It makes up for the problem of the single nutritional content of traditional rice, improves its nutritional value, and balances the different maturation times of different types of rice. It is more convenient to cook and eat and is widely used in self-heating rice.

[0003] A search revealed application CN202320037406.1, entitled "A Mixing Structure for Compound Nutritional Rice Flour Processing." This application proposes a mixing structure for compound nutritional rice flour. By incorporating a dust suppression mechanism, the mixing structure can handle the dust raised in the hopper, solving the problem of poor environmental performance of existing mixing devices and the potential impact of dust on worker health and the surrounding environment during mixing. However, the dust generated during rice flour mixing is still part of the raw material. Removing it using a suction device changes the total weight, and this portion of rice dust is not mixed in a timely manner, affecting the final product's proportions and causing waste due to the inability to recycle the rice dust promptly. Further improvements are needed. Additionally, the application uses a movable door for unloading, which makes it difficult to control the stability of the discharge and ensures consistent quantitative output, affecting the stability of subsequent packaging and processing. These aspects also require further improvement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (II) Technical Solution To achieve the advantages of good sealing, prevention of rice flour leakage, and improved production efficiency, the specific technical solution adopted by this utility model is as follows: A multifunctional compound nutrient rice ingredient mixing device includes a mixing tank and an ingredient mixing tank. A feeding pipe is slidably connected to the top surface of the mixing tank, and the top surface of the feeding pipe is connected to the ingredient mixing tank. A servo motor is fixedly installed on the top surface of the ingredient mixing tank. A shaft is installed at the output end of the servo motor, and an auger is welded to the bottom surface of the shaft. A discharge channel is connected to the bottom surface of the mixing tank, and a discharge bin is connected to the bottom surface of the discharge channel. A discharge shaft is rotatably connected to the central axis of the discharge bin. A discharge plate is welded to the surface of the discharge shaft, and a sealing strip is fixedly adhered to the edge of the discharge plate, slidingly abutting against the inner wall of the discharge bin. A drive motor is fixedly installed on the top surface of the mixing tank, and a stirring paddle is installed at the output end of the drive motor. A stepper motor is fixedly installed on the front surface of the discharge bin, and the output end of the stepper motor is fixedly connected to one end of the discharge shaft.

[0007] Furthermore, a vibration motor is fixedly installed on the surface of the mixing tank.

[0008] Furthermore, a slide gate valve is fixedly installed on the surface of the unloading channel.

[0009] Furthermore, a feed hopper is connected through the top surface of the mixing tank, and a top cover is hinged to the top opening of the feed hopper.

[0010] Furthermore, the bottom opening of the unloading hopper is connected to a discharge port.

[0011] Furthermore, a bracket is fixedly connected to the top surface of the mixing tank outside the ingredient tank, and a weighing sensor is fixedly installed on the top surface of the bracket. A side ring is fixedly connected to the outer wall of the ingredient tank, and the bottom surface of the side ring is fixedly connected to the detection end of the top surface of the weighing sensor.

[0012] Furthermore, the unloading plates are distributed in six groups at equal angles along the unloading axis.

[0013] Furthermore, the stepping angle of the stepper motor is matched with the included angle of the unloading plate.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a multifunctional compound nutrient rice ingredient mixing device, which has the following beneficial effects: (1) This utility model adopts a weighing sensor and a discharge bin. When mixing compound nutrient rice, rice flour containing different nutrients can be put into the mixing tank. The servo motor drives the shaft to rotate, which in turn drives the auger to rotate and put the rice flour into the mixing tank. The weighing sensor weighs the weight reduction of the mixing tank. When the set value is reached, the weighing sensor shuts off the servo motor through the cooperating controller, thus completing the quantitative feeding. During the feeding process, the drive motor starts synchronously and drives the stirring paddle to rotate and mix the various rice flours. After the mixing is completed, the slide valve opens and the stepper motor drives the discharge plate to rotate. The mixed rice flour that falls between the discharge plates is conveyed out of the discharge port by the continuously flipping discharge plate. The edge of the discharge plate is bonded with a sealing strip, which slides against the inner wall of the discharge bin to play a good sealing role, avoiding rice flour dust leakage during discharge and avoiding the problem of reduced total weight caused by rice flour dust leakage, thus improving the accuracy of the mixing. At the same time, the sealing is good throughout the mixing process, avoiding the problem of rice flour dust leakage and facilitating clean production.

[0015] (2) This utility model adopts a vibration motor and a stepper motor. The stepper motor drives the unloading plate to rotate at the same angle. At the same time, the vibration motor starts synchronously during unloading. By vibrating, the bridging effect of the powder is broken, so that it can smoothly enter between the unloading plates, thus facilitating equal unloading. The bottom of the discharge port can be directly connected to the feed port of the extrusion molding equipment of the compound nutrient rice. By unloading in equal quantities, the uneven extrusion caused by uneven entry of raw materials during extrusion is avoided, which improves the working efficiency and molding stability of nutrient rice to a certain extent.

Detailed Implementation

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a multifunctional compound nutrient rice ingredient mixing device is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to them. Figure 1 and Figure 2 A multifunctional compound nutrient rice ingredient mixing device according to an embodiment of the present invention includes a mixing tank 1 and ingredient mixing tanks 12. The mixing tank 1 is made of 304 stainless steel, with a diameter of 800mm, a height of 1200mm, a tank wall thickness of 3mm, and a mirror-polished surface with a roughness Ra≤0.8μm. Four groups of ingredient mixing tanks 12 are evenly distributed along the central axis of the mixing tank 1, each corresponding to a different type of rice flour with different nutritional components. The number of ingredient mixing tanks 12 equals the number of types of rice flour, satisfying the need for combining multiple nutrients. A feeding pipe 19 is slidably connected to the top surface of mixing tank 1. The feeding pipe 19 is made of 304 stainless steel with a diameter of 100mm and is slidably connected to the top surface of mixing tank 1 via a linear bearing. The sliding accuracy is ±0.1mm, ensuring smooth movement of the feeding pipe 19. A cloth sleeve can be fitted between the outer wall of the feeding pipe 19 and the top surface of the ingredient tank 12. The cloth sleeve is made of wear-resistant nylon canvas, and its two ends are sealed to the outer wall of the feeding pipe 19 and the top surface of the ingredient tank 12 respectively via stainless steel clamps. This further prevents rice flour dust leakage, improves sealing performance, and, due to the good deformation capacity of the cloth sleeve, does not affect the movement of the feeding pipe 19. This is a common dustproof structure and is not shown in the figure. The top surface of the feeding pipe 19 is connected to the ingredient tank 12, which is made of transparent acrylic material for easy observation of the remaining rice flour. The tank has a diameter of 300mm and a height of 500mm. A servo motor 13 is bolted to the top surface of the mixing tank 12. The servo motor 13 is model 110ST-M06030, with a rated power of 0.6kW and an adjustable speed of 0-3000r / min. A shaft 15 is mounted on the output end of the servo motor 13 via a coupling. The shaft 15 is made of 45# steel with a diameter of 20mm, and an auger 16 is welded to the bottom surface of the shaft 15. The auger 16 has a pitch of 50mm and extends into the feeding pipe 19. The blades of the auger 16 slide against the inner wall of the feeding pipe 19 with a gap of ≤0.5mm to prevent rice powder leakage when not rotating. The bottom surface of the mixing tank 1 is connected to a discharge channel 4, which is 200mm wide, and the bottom surface of the discharge channel 4 is also connected to a discharge bin 6. A discharge shaft 8 is rotatably connected through the central axis of the discharge bin 6. The discharge shaft 8 has a diameter of 30mm and a discharge plate 9 welded to its surface. The discharge plate 9 has a thickness of 5mm, and a sealing strip 10 is fixedly bonded to the edge of the discharge plate 9. The sealing strip 10 is made of food-grade silicone with a Shore hardness of 60A. The sealing strip 10 slides against the inner wall of the discharge bin 6 to form a seal and prevent the rice flour and gas from leaking out when not discharging. A drive motor 2, model Y132M-4, with a rated power of 7.5kW and a speed of 1440r / min, is bolted to the top surface of the mixing tank 1. A stirring paddle 3, with a double-layer blade structure and a diameter of 600mm, is mounted on the output end of the drive motor 2 via a reducer. This is a common mixing structure that ensures uniform mixing of the rice flour. A stepper motor 18, model 86BYG250, with a step angle of 1.8° and a positioning accuracy of ±0.05°, is bolted to the front surface of the unloading hopper 6. The output end of the stepper motor 18 is fixedly connected to one end of the unloading shaft 8 via a coupling. The unloading shaft 8 is rotatably connected to the unloading hopper 6 via a sealed bearing with an IP65 sealing rating to prevent dust from entering the bearing. When mixing compound nutrient rice, rice flour containing different nutrients can be placed into the mixing tank 12. The servo motor 13 drives the shaft 15 to rotate, which in turn drives the auger 16 to rotate and feed the rice flour into the mixing tank 1. The feeding speed can be adjusted by the speed of the servo motor 13, ranging from 10-50 kg / h. The weighing sensor 21 weighs the weight reduction of the mixing tank 12, with a weighing accuracy of ±1g. When the set value is reached, the weighing sensor 21 shuts off the servo motor 13 through the cooperating controller, thus completing the quantitative feeding.

[0022] During the feeding process, the drive motor 2 starts synchronously, driving the stirring paddle 3 to rotate at a speed of 300 r / min to mix various types of rice flour. After mixing, the slide valve 5 opens, and the stepper motor 18 drives the unloading plate 9 to rotate. The mixed rice flour falling between the unloading plates 9 is conveyed out of the discharge port 7 by the continuously rotating unloading plates 9. The edge of the unloading plate 9 is bonded with a sealing strip 10, which slides against the inner wall of the unloading bin 6, providing a good seal and preventing rice flour dust leakage during unloading. This avoids the problem of reduced total weight caused by rice flour dust leakage, improves the accuracy of the batching, and the batching error is ≤0.5%. At the same time, the good sealing performance throughout the batching process allows the dust concentration in the workshop to be controlled below 2mg / m³, preventing rice flour dust leakage and facilitating clean production. Please refer to Figure 1 and Figure 2 A vibration motor 11, model YZU-10-2, with a vibration force of 10kN and a speed of 2850r / min, is bolted to the surface of the mixing tank 1. A stepper motor 18 drives the discharge plate 9 to rotate at equal angles, 60° each time. Simultaneously, the vibration motor 11 starts during discharge, breaking the bridging effect of the powder through vibration, allowing it to smoothly enter between the discharge plates 9, thus facilitating equal-volume discharge with minimal error. The bottom of the discharge port 7 can be directly connected to the inlet of the extrusion molding equipment for compound nutritional rice. Equal-volume discharge avoids uneven extrusion caused by uneven raw material entry, improving work efficiency and the molding stability of the nutritional rice, significantly increasing the product qualification rate. Please refer to Figure 1 and Figure 2 The unloading channel 4 is fixedly installed with a slide gate valve 5 via a flange. The unloading channel 4 is closed during mixing and opened during unloading to facilitate the rice noodles entering the unloading hopper 6. When closed, it has good sealing performance and no leakage. Please refer to Figure 1 and Figure 2 The top surface of the mixing tank 12 is welded with a feed hopper 14. The feed hopper 14 has a conical structure with an upper diameter of 200mm and a height of 150mm. The top opening of the feed hopper 14 is hinged with a cover made of food-grade PP material, which facilitates sealing of the feed hopper 14 to prevent dust from entering and rice flour from getting damp. Please refer to Figure 1 and Figure 2 The bottom opening of the unloading hopper 6 is welded with a discharge port 7, which has a diameter of 150mm to facilitate material discharge. A conveying pipeline can be connected to the extrusion equipment below the discharge port 7. Please refer to Figure 3 and Figure 4 A bracket 17 is fixedly welded to the top surface of the mixing tank 1, located outside the ingredient tank 12. A weighing sensor 21 is bolted to the top surface of the bracket 17. The weighing sensor 21 is model YZC-133, with a range of 0-50kg and an accuracy of 0.1%. A side ring 20 is fixedly welded to the outer wall of the ingredient tank 12. The side ring 20 is made of 304 stainless steel, with a width of 50mm. The bottom surface of the side ring 20 is bolted to the detection end of the top surface of the weighing sensor 21. The output end of the weighing sensor 21 is electrically connected to the input end of the servo motor 13 through a matching controller. This is a common weighing control structure, which will not be described in detail here, ensuring the accuracy of quantitative dispensing. Please refer to Figure 1 and Figure 2 The unloading plates 9 are distributed in six groups at equal angles along the unloading shaft 8. The included angle between adjacent unloading plates 9 is 60°. The stepper motor 18 advances at an angle that matches the included angle of the unloading plates 9. Each step corresponds to a 60° rotation of the unloading plates 9, which facilitates the positioning and rotation of the unloading plates 9 and ensures uniform unloading. Working principle: When mixing the ingredients for compound nutrient rice, rice flour with different nutritional components is first added to the corresponding ingredient tanks 12 through the feed hopper 14, and the lids are closed to prevent dust contamination and moisture absorption of the rice flour. According to the formula requirements, the amount of each type of rice flour is set in the controller, the device is started, and the servo motor 13 starts according to the set program, driving the shaft 15 and the auger 16 to rotate, conveying the rice flour in the ingredient tank 12 to the mixing tank 1 through the feeding pipe 19. During the dispensing process, the weighing sensor 21 monitors the weight change of the ingredient tank 12 in real time. When the weight decrease reaches the set value, the controller sends a signal to shut down the corresponding servo motor 13, stopping the dispensing of that type of rice noodles. At the same time, the drive motor 2 drives the stirring paddle 3 to rotate, stirring and mixing the various rice noodles put into the mixing tank 1 to ensure that the various nutrients are evenly distributed. After mixing, the gate valve 5 is opened, and the mixed rice noodles enter the discharge hopper 6 through the discharge channel 4, falling between the discharge plates 9. The stepper motor 18 is started, driving the discharge shaft 8 and the discharge plates 9 to rotate intermittently at a set angle (60°). At the same time, the vibration motor 11 is started, and the vibration helps the rice noodles to smoothly enter between the discharge plates 9, avoiding bridging. As the discharge plates 9 rotate, they push the rice noodles to the discharge port 7, from which they are transported to the subsequent extrusion molding equipment. During the unloading process, the sealing strip 10 on the edge of the unloading plate 9 is in close contact with the inner wall of the unloading hopper 6 to prevent rice flour leakage and dust from flying. The entire batching process realizes automated quantitative feeding, mixing and unloading, reducing manual intervention, improving batching accuracy and work efficiency, while ensuring a clean production environment, making it suitable for large-scale production and processing of compound nutritional rice.
