Description

Technical Field

[0001] This utility model relates to the field of soybean protein isolate processing technology, and in particular to a powder mixing device for soybean protein isolate processing. Background Technology

[0002] Soy protein isolate is a high-purity protein product extracted from soybeans. It is obtained after removing the fat and most of the carbohydrates from soybeans. Its protein content is usually higher than 90% and it contains almost no fat. Due to its excellent nutritional value and functional properties, it is widely used in the food industry, including as an emulsifier, thickener, and stabilizer. It can also be used to produce vegetarian products and meat substitutes.

[0003] In the processing of soy protein isolate, the performance of the mixing equipment is crucial to ensure that it is fully mixed with other ingredients in order to prepare high-quality food or nutritional supplements. Traditional mixing devices usually only have one mixing shaft, which can only provide force in one direction and often cannot effectively achieve uniform mixing of powders, thus affecting the quality of the final product.

[0004] Therefore, there is an urgent need to provide a powder mixing device for processing soybean protein isolate with a multi-axis stirring structure. Utility Model Content

[0005] To overcome the shortcomings of traditional mixing devices that typically only have one mixing shaft and can only provide force in one direction, thus failing to effectively achieve uniform mixing of powders and affecting the quality of the final product, this utility model provides a powder mixing device for processing soybean protein isolate with a multi-shaft mixing structure.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a powder mixing device for processing soybean protein isolate, comprising a support base, a mixing hopper mounted on the support base, a cover plate on the top of the mixing hopper, multiple positioning seats fixedly connected to the upper part of the support base, and a discharge plate rotatably mounted on adjacent front and rear positioning seats. Torsion springs are fitted at both ends of the discharge plate, and pins are provided on the discharge plate to fix its position. The device also includes a dual-head motor mounted at the front end of the mixing hopper to provide a power source. The center position of the mixing hopper rotates... A connecting rod is movably installed, one end of which is connected to the output shaft of a dual-head motor. A first mixing rack is provided on the connecting rod, and a first bevel gear is provided at the end of the first mixing rack away from the dual-head motor. A second mixing rack is rotatably installed at the center of the mixing barrel. The connecting rod rotates through the middle of the second mixing rack. A second bevel gear is installed at the end of the mixing barrel near the first bevel gear, and the second bevel gear meshes with the first bevel gear. A third bevel gear is provided at the end of the second mixing rack near the second bevel gear, and the third bevel gear meshes with the second bevel gear.

[0007] Optionally, it also includes a vibration mechanism, which includes an annular connecting frame. The annular connecting frame is mounted on the output shaft at the front end of the dual-head motor. Multiple inclined blocks are fixedly connected to the inner arc surface of the annular connecting frame. Positioning frames are fixedly connected to both sides of the support base. A striking plate is slidably mounted on the positioning frame. A contact plate that contacts and cooperates with the inclined blocks is fixedly connected to the striking plate. A first elastic element is connected between the striking plate and the positioning frame.

[0008] Optionally, it also includes an auxiliary cleaning mechanism, which includes a guide frame that slides through the inside of the mixing tank. One end of the guide frame is provided with an annular connecting plate, and a scraper is provided on the annular connecting plate. A second elastic element connects the guide frame and the mixing tank.

[0009] Optionally, it also includes a protective shell, wherein the mixing barrel is provided with a protective shell at one end near the first bevel gear, and the first bevel gear, the second bevel gear and the third bevel gear are located inside the protective shell.

[0010] Optionally, it also includes a protective sleeve, with protective sleeves fitted at both ends of the ejector plate, and a torsion spring located inside the protective sleeve.

[0011] Optionally, it also includes a material collection frame, which is provided on the support base below the mixing tank.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The device is equipped with a dual-shaft stirring mechanism and adopts a dual-shaft counter-rotation design. During the mixing process, the material is not only pushed by the axial direction, but also subjected to radial and tangential shear forces, which enhances the mutual mixing between the materials. This allows the materials to reach a uniform distribution state in a shorter time, thereby significantly improving the uniformity and efficiency of mixing.

[0013] 2. This device is equipped with a vibration mechanism. The mixing drum is periodically tapped by a tapping plate, which helps to shake off the material adhering to the drum wall, reducing uneven mixing or material waste caused by material adhesion, and also helps to improve material utilization.

[0014] 3. This device is equipped with an auxiliary cleaning mechanism. Through the design of the guide frame and scraper, the inner wall of the mixing tank can be easily cleaned. This not only ensures the hygiene of the equipment, but also simplifies the maintenance work and further improves the efficiency and reliability of the equipment. Attached Figure Description

[0023] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0024] Example 1: Please refer to Figure 1 , Figure 2 Forehead Figure 4A powder mixing device for processing soy protein isolate includes a support base 1, on which a mixing tank 2 is mounted for loading soy protein isolate powder and other ingredients to be mixed. A cover plate 8 is mounted on the top of the mixing tank 2. Four symmetrically arranged positioning seats 9 are fixedly connected to the upper part of the support base 1. A discharge plate 10 is rotatably mounted on adjacent front and rear positioning seats 9. Torsion springs 11 are fitted at both ends of the discharge plate 10. Initially, the torsion springs 11 are compressed. Pins 12 are provided on the discharge plate 10 to fix its position and ensure proper mixing during the process. The material discharge plate 10 will not open due to material pressure. Protective sleeves 24 are fitted at both ends of the discharge plate 10, and a torsion spring 11 is located inside the protective sleeve 24. The main function of the protective sleeve 24 is to protect the torsion spring 11 from external environmental influences, preventing dust, moisture, and other impurities from entering the spring and causing corrosion or failure. A collection frame 25 is provided on the support base 1 below the mixing tank 2. The collection frame 25 is used to collect the material discharged from the mixing tank 2 during unloading, ensuring that the material is collected centrally and does not scatter, facilitating subsequent processing or packaging. It also includes a dual-shaft stirring mechanism. On the mixing hopper 2, the dual-head motor 3 is installed at the front end of the mixing hopper 2 to provide a power source. A connecting rod 4 is rotatably installed at the center of the mixing hopper 2. One end of the connecting rod 4 is connected to the output shaft of the dual-head motor 3. A first mixing frame 5 is provided on the connecting rod 4, which is directly driven by the dual-head motor 3 to rotate in the forward direction. A first bevel gear 6 is provided at the end of the first mixing frame 5 away from the dual-head motor 3 for power transmission. A second mixing frame 7 is rotatably installed at the center of the mixing hopper 2. The connecting rod 4 rotatably passes through the middle of the second mixing frame 7. A first bevel gear 6 is installed at the end of the mixing hopper 2 near the first bevel gear 6. Two bevel gears 601 mesh with the first bevel gear 6. A third bevel gear 602 is provided at one end of the second mixing rack 7 near the second bevel gear 601. The third bevel gear 602 meshes with the second bevel gear 601 and is used to drive the second mixing rack 7 to rotate in the opposite direction. A protective shell 23 is provided at one end of the mixing barrel 2 near the first bevel gear 6. The first bevel gear 6, the second bevel gear 601, and the third bevel gear 602 are located inside the protective shell 23, which can prevent external impurities from entering the bevel gear set and avoid contamination or damage to the bevel gears, thereby ensuring the normal operation of the transmission system.

[0025] First, open the cover plate 8 and add the soy protein isolate powder and other required ingredients into the mixing tank 2. Then, close and secure the cover plate 8 again. After starting the dual-head motor 3, the output shaft at one end of the motor drives the first mixing rack 5 to rotate in the forward direction. The meshing transmission between the first bevel gear 6 and the second bevel gear 601 causes the second bevel gear 601 to drive the third bevel gear 602, which in turn causes the second mixing rack 7 to rotate in the reverse direction. Since the two mixing shafts rotate in opposite directions, the material will be subjected to multiple mixing actions in the axial, radial and tangential directions during the mixing process, thereby ensuring that the material can be mixed more evenly in the tank. After the mixing is completed, remove the pin 12 and use the torsion spring 11 on the unloading plate 10 to automatically flip and discharge the material, completing the unloading process.

[0026] Example 2: Based on Example 1, please refer to... Figure 5 It also includes a vibration mechanism, which includes an annular connecting frame 13. The annular connecting frame 13 is mounted on the output shaft at the front end of the dual-head motor 3. Four inclined blocks 14 are fixedly connected to the inner arc surface of the annular connecting frame 13. Positioning frames 15 are fixedly connected to both the left and right sides of the support base 1. A striking plate 17 is slidably mounted on the positioning frame 15. A contact plate 16 that contacts and cooperates with the inclined blocks 14 is fixedly connected to the striking plate 17. A first elastic element 18 is connected between the striking plate 17 and the positioning frame 15, and the first elastic element 18 is sleeved on the striking plate 17 to provide the elastic force required for the striking plate 17 to reset.

[0027] During the powder mixing process, the output shaft at the other end of the dual-head motor 3 drives the annular connecting frame 13 to rotate. As the annular connecting frame 13 continues to rotate, the inclined block 14 fixed on it contacts the contact plate 16 on the patting plate 17 in sequence. When the inclined surface of the inclined block 14 presses against the contact plate 16, the patting plate 17 moves horizontally inward, and the first elastic element 18 is compressed accordingly. The movement of the patting plate 17 will produce a patting effect on the outer wall of the mixing barrel 2, thereby causing the mixing barrel 2 to vibrate. When the annular connecting frame 13 continues to rotate, after the inclined block 14 and the contact plate 16 are separated, the pressing force acting on the contact plate 16 disappears. At this time, under the restoring elastic force of the first elastic element 18, the patting plate 17 quickly resets. This process is repeated. The patting plate 17 moves continuously and pats the outer wall of the mixing barrel 2, so that the mixing barrel 2 produces a continuous vibration effect, which helps to shake off the powder adhering to the barrel wall, thereby avoiding the agglomeration phenomenon formed by the powder due to adhesion during the mixing process and ensuring the uniformity of material mixing.

[0028] Please see Figure 6 and Figure 7It also includes an auxiliary cleaning mechanism, which includes a guide frame 19 that slides through the inside of the mixing tank 2. One end of the guide frame 19 is provided with an annular connecting plate 20, and a scraper 21 is provided on the annular connecting plate 20. The scraper 21 can slide along the tank wall to remove residual material. A second elastic element 22 is connected between the guide frame 19 and the mixing tank 2, and the second elastic element 22 is sleeved on the guide frame 19. The second elastic element 22 provides the scraper 21 with the restoring force required when sliding along the tank wall.

[0029] When it is necessary to clean the inner wall of the mixing tank 2, the operator can pull the guide frame 19 outward, so that the scraper 21 fixed on the annular connecting plate 20 moves along the tank wall of the mixing tank 2 to perform the cleaning operation. During the process of pulling the guide frame 19, the second elastic element 22 will be compressed and store a certain amount of elastic potential energy. When the guide frame 19 is released, the second elastic element 22 releases its stored energy, so that the guide frame 19 and the scraper 21 on it quickly return to the initial position, easily achieving the cleaning of the inner wall of the mixing tank 2.

[0030] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
