Description

Technical Field

[0001] This application relates to the field of food processing technology, specifically to a mixing device for producing yogurt pudding. Background Technology

[0002] Yogurt pudding, a popular dairy dessert, holds a significant position in the market due to its delicate texture, rich nutrition, and diverse flavors. Its production process typically involves the precise mixing of various ingredients, such as yogurt, jam, gelatin, and sugar, to ensure a consistent texture and taste in the final product.

[0003] However, the mixing method of traditional agitators is relatively simple. In actual production, the mixing effect of raw materials is often affected by a variety of factors, especially the addition of high-viscosity materials. This makes it difficult for the shear force generated by the agitator to act evenly on the entire material system during the mixing process, resulting in stratification. At the same time, local high shear force areas are formed near the traditional agitator or in certain corners of the container, while the mixing force is insufficient in other areas, which easily leads to clumping and affects the taste and quality of the product. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a mixing device for producing yogurt pudding. This device features multi-stage mixing to break the stratification phenomenon in traditional unidirectional mixing modes, while significantly reducing the risk of aggregation in local high-shear areas, greatly improving mixing uniformity, and suppressing agglomeration. These advantages solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a mixing device for producing yogurt pudding, comprising a mixing tank, a drive motor fixedly embedded in the upper surface of the mixing tank, a shearing and mixing assembly disposed inside the mixing tank, the shearing and mixing assembly comprising a first rotating shaft rotatably connected to the inner side of the mixing tank, the output end of the drive motor fixedly connected to one end of the first rotating shaft, a first bevel gear fixedly connected to the other end of the first rotating shaft, two sets of four-bladed turbine propellers fixedly connected to the outer surface of the first rotating shaft, and a spiral mixing assembly disposed inside the mixing tank, the spiral mixing assembly comprising... A second rotating shaft has a second bevel gear fixedly connected to one end. Spiral blades are fixedly installed on the outer surface of the second rotating shaft. A protective box is provided inside the mixing tank. The inner walls of the first and second rotating shafts are rotatably connected to the inner wall of the protective box. A connecting shaft is rotatably connected to the inner wall of the protective box. A third bevel gear is fixedly connected to one end of the connecting shaft. The first and second bevel gears are meshed with the third bevel gear. Three support rods are fixedly connected to the side of the protective box, and the other ends of the support rods are fixedly connected to the inner side of the mixing tank.

[0006] Through the above scheme, the meshing transmission design of the first, second and third bevel gears enables the first and second rotating shafts to rotate synchronously in opposite directions. At this time, the drive motor drives the first rotating shaft to drive the four-bladed turbine to generate high-speed shear force to disperse high-viscosity materials, while the second rotating shaft rotates in the opposite direction to drive the spiral blades to generate spiral lift force, continuously lifting the material in the central area upward, breaking the stratification phenomenon in the traditional unidirectional stirring mode. At the same time, the convective shear effect generated by the reverse rotation causes the material to form a bidirectional vortex inside the mixing tank, which greatly reduces the risk of aggregation in local high-shear areas, significantly improves the mixing uniformity and inhibits the formation of agglomerates.

[0007] Furthermore, a sealing ring is fixedly connected to one side of the protective box, and a sealing cover is fixedly installed on the side of the protective box.

[0008] The above solution enhances the sealing performance of the protective box by combining a sealing ring and a sealing cover, preventing materials from seeping into the gaps of the transmission components, avoiding mechanical jamming or contamination problems caused by residue accumulation, while reducing maintenance frequency and improving the operational stability of the device.

[0009] Furthermore, a heating ring is fixedly installed on the outer side of the mixing tank, a controller is fixedly installed on the upper surface of the mixing tank, and a temperature sensor is fixedly installed on the inner side of the mixing tank. Both the heating ring and the temperature sensor are electrically connected to the controller.

[0010] The above-mentioned scheme, which sets up a temperature control system consisting of a heating ring, a controller, and a temperature sensor, achieves precise temperature control by adjusting the heating power of the heating ring in real time through the controller and combining the dynamic feedback of the material temperature from the temperature sensor. This avoids material denaturation or uneven coagulant reaction caused by temperature control lag in traditional devices, and ensures viscosity stability during the mixing process.

[0011] Furthermore, a feed pipe is fixedly installed on the upper surface of the mixing tank, a discharge pipe is fixedly installed at the lower end of the mixing tank, and a solenoid valve is fixedly installed on the outside of the discharge pipe.

[0012] The above solution uses a solenoid valve to control the discharge flow rate via electromagnetic control. Combined with the inclined structure of the discharge pipe, it avoids the accumulation and blockage of high-viscosity materials at the discharge port, thereby improving the efficiency of continuous production.

[0013] Furthermore, two first fixed seats are fixedly connected to the outer surface of the first rotating shaft, and four first connecting rods in a circumferential array are fixedly connected to the outside of each of the two first fixed seats. Four first scrapers in a circumferential array are provided on the outside of the first rotating shaft, and the outer surface of the first scrapers is fixedly connected to one end of the first connecting rod.

[0014] The above solution involves fixing the first scraper with a first fixed base and a first connecting rod, so that the first scraper moves closely against the inner wall of the mixing tank during rotation, ensuring that the first scraper stably scrapes off the material adhering to the inside of the mixing tank.

[0015] Furthermore, one side of the first scraper near the inner side of the mixing tank is curved, and another side of the first scraper is inclined.

[0016] Through the above scheme, the arc and slope design of the first scraper enhances the scraping effect on the residual material on the container wall. At the same time, the periodic disturbance breaks the material boundary layer, improving the mixing uniformity. Meanwhile, the slope structure further guides the material to flow towards the central area, strengthening the coverage of shearing and convection.

[0017] Furthermore, two second fixed seats are fixedly connected to the outer surface of the second rotating shaft, and four circumferentially arrayed second connecting rods are fixedly connected to the outer surface of each of the two second fixed seats. Four circumferentially arrayed stirring rods are provided on the outside of the second rotating shaft, and the two ends of the stirring rods are fixedly connected to the outer surface of the second connecting rods.

[0018] The above scheme, by setting a second fixed base and a second connecting rod to support the stirring rod and the second scraper, allows the stirring rod to form multi-directional turbulence during the spiral stirring process, thereby further improving the stirring performance.

[0019] Furthermore, the outer side of the second rotating shaft is provided with four circumferentially arrayed second scrapers, and the outer surface of the second scrapers is fixedly connected to one end of the second connecting rod. The side of the second scraper near the inner side of the mixing tank is set with an arc surface, and the other side of the second scraper is set with an inclined surface.

[0020] The above scheme, by setting the arc and slope design of the second scraper, can enhance the scraping effect on the residual material on the container wall, and at the same time, the material boundary layer is broken by periodic disturbance, thereby improving the mixing uniformity.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This mixing device for producing yogurt pudding uses a meshing transmission design of a first bevel gear, a second bevel gear, and a third bevel gear to enable the first and second rotating shafts to rotate synchronously in opposite directions. At this time, the drive motor drives the first rotating shaft to drive a four-bladed turbine to generate high-speed shear force to disperse high-viscosity materials. Meanwhile, the second rotating shaft rotates in the opposite direction to drive the spiral blades to generate spiral lift force, continuously lifting the material in the central area upward. This breaks the stratification phenomenon in the traditional unidirectional stirring mode. At the same time, the convective shear effect generated by the reverse rotation causes the material to form a bidirectional vortex inside the mixing tank, which greatly reduces the risk of aggregation in local high-shear areas, significantly improves the mixing uniformity, and inhibits the formation of agglomerates.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 3 and Figure 4The mixing device for producing yogurt pudding in this embodiment includes a mixing tank 1. A drive motor 2 is fixedly embedded on the upper surface of the mixing tank 1. A shearing and mixing assembly 3 is provided inside the mixing tank 1. The shearing and mixing assembly 3 includes a first rotating shaft 301 rotatably connected to the inner side of the mixing tank 1. The output end of the drive motor 2 is fixedly connected to one end of the first rotating shaft 301. A first bevel gear 303 is fixedly connected to the other end of the first rotating shaft 301. Two sets of four-bladed turbine propellers 302 are fixedly connected to the outer surface of the first rotating shaft 301. A spiral mixing assembly 4 is provided inside the mixing tank 1. The spiral mixing assembly 4 includes a second rotating shaft 401. A second bevel gear 402 is fixedly connected to one end of the second rotating shaft 401. Spiral blades 403 are fixedly installed on the outer surface of the second rotating shaft 401. A protective box 5 is provided inside the mixing tank 1. The inner walls of the first rotating shaft 301 and the inner walls of the second rotating shaft 401 are both rotatably connected to the protective box 5. The inner wall of the protective box 5 is rotatably connected to a connecting shaft 6. One end of the connecting shaft 6 is fixedly connected to a third bevel gear 7. The first bevel gear 303 and the second bevel gear 402 are both meshed with the third bevel gear 7. Through the meshing transmission design of the first bevel gear 303, the second bevel gear 402 and the third bevel gear 7, the first rotating shaft 301 and the second rotating shaft 401 achieve synchronous rotation in opposite directions. At this time, the drive motor 2 drives the first rotating shaft 301 to drive the four-bladed turbine propeller 302 to generate high-speed shear force to disperse high-viscosity materials. Meanwhile, the second rotating shaft 401 rotates in the opposite direction to drive the spiral blade 403 to form a spiral lift force, continuously lifting the material in the central area upward, breaking the stratification phenomenon in the traditional unidirectional stirring mode. At the same time, the convective shear effect generated by the reverse rotation causes the material to form a bidirectional vortex inside the mixing tank 1, which greatly reduces the risk of aggregation in local high-shear areas, significantly improves the mixing uniformity and inhibits the formation of agglomerates.

[0032] Please see Figure 1 , Figure 2 and Figure 5Three support rods 8 are fixedly connected to the side of the protective box 5, and the other end of the support rods 8 is fixedly connected to the inside of the mixing tank 1. A sealing ring 9 is fixedly connected to one side of the protective box 5, and a sealing cover plate 10 is fixedly installed on the side of the protective box 5. The combination design of the sealing ring 9 and the sealing cover plate 10 enhances the sealing performance of the protective box 5, prevents materials from seeping into the gaps of the transmission components, avoids mechanical jamming or contamination problems caused by the accumulation of residues, and reduces the maintenance frequency and improves the operational stability of the device. A heating ring 11 is fixedly installed on the outside of the mixing tank 1, a controller 12 is fixedly installed on the upper surface of the mixing tank 1, and a temperature sensor 13 is fixedly installed on the inside of the mixing tank 1. The heating ring 11 and the temperature sensor 13 are both electrically connected to the controller 12. The above-mentioned temperature control system, consisting of heating ring 11, controller 12, and temperature sensor 13, achieves precise temperature control by adjusting the heating power of heating ring 11 in real time through controller 12 and dynamically feeding back the material temperature from temperature sensor 13. This avoids material denaturation or uneven coagulant reaction caused by temperature control lag in traditional devices, ensuring viscosity stability during mixing. A feed pipe 14 is fixedly installed on the upper surface of mixing tank 1, and a discharge pipe 15 is fixedly installed at the lower end of mixing tank 1. A solenoid valve 16 is fixedly installed on the outside of discharge pipe 15. The discharge flow rate is adjusted by electromagnetic control through solenoid valve 16. Combined with the inclined structure of discharge pipe 15, this prevents high-viscosity materials from accumulating and clogging at the discharge port, improving continuous production efficiency.

[0033] Please see Figure 1 and Figure 3 Two first fixed seats 304 are fixedly connected to the outer surface of the first rotating shaft 301. Four first connecting rods 305 in a circular array are fixedly connected to the outside of each of the two first fixed seats 304. Four first scrapers 306 in a circular array are provided on the outside of the first rotating shaft 301, and the outer surface of the first scraper 306 is fixedly connected to one end of the first connecting rod 305. By setting the first fixed seats 304 to fix the first scrapers 306 through the first connecting rods 305, the first scrapers 306 move closely against the inner wall of the mixing tank 1 during rotation, ensuring that the first scrapers 306 stably scrape off the material adhering to the inside of the mixing tank 1. The side of the first scraper 306 near the inner side of the mixing tank 1 is set with an arc surface, and the other side of the first scraper 306 is set with an inclined surface. The above-mentioned arc surface and inclined surface design of the first scraper 306 enhances the scraping effect on the residual material on the container wall. At the same time, the periodic disturbance breaks the material boundary layer, improves the mixing uniformity, and the inclined surface structure further guides the material to flow towards the central area, strengthening the coverage of shearing and convection.

[0034] Please see Figure 1 and Figure 4Two second fixed seats 404 are fixedly connected to the outer surface of the second rotating shaft 401. Four circumferentially arrayed second connecting rods 405 are fixedly connected to the outer surface of each of the two second fixed seats 404. Four circumferentially arrayed stirring rods 406 are provided outside the second rotating shaft 401, with both ends of the stirring rods 406 fixedly connected to the outer surface of the second connecting rods 405. By setting the second fixed seats 404 and the second connecting rods 405 to support the stirring rods 406 and the second scraper 407, the stirring rods 406 form a multi-directional stirring pattern during the spiral stirring process. The second rotating shaft 401 is equipped with four circumferentially arrayed second scrapers 407 on its outer side, and the outer surface of the second scrapers 407 is fixedly connected to one end of the second connecting rod 405. The side of the second scraper 407 near the inner side of the mixing tank 1 is set with an arc surface, and the other side of the second scraper 407 is set with an inclined surface. By setting the arc surface and inclined surface design of the second scraper 407, the scraping effect on the residual material on the container wall can be enhanced. At the same time, the material boundary layer is broken by periodic disturbance, thereby improving the mixing uniformity.

[0035] In this embodiment, the mixing device for producing yogurt pudding uses a meshing transmission design of the first bevel gear 303, the second bevel gear 402, and the third bevel gear 7 to enable the first rotating shaft 301 and the second rotating shaft 401 to rotate synchronously in opposite directions. At this time, the drive motor 2 drives the first rotating shaft 301 to drive the four-bladed turbine propeller 302 to generate high-speed shear force to disperse high-viscosity materials. Meanwhile, the second rotating shaft 401 rotates in the opposite direction to drive the spiral blades 403 to generate spiral lift force, continuously lifting the material in the central area upward, breaking the stratification phenomenon in the traditional unidirectional stirring mode. At the same time, the convective shear effect generated by the reverse rotation causes the material to form a bidirectional vortex inside the mixing tank 1, which greatly reduces the risk of aggregation in local high-shear areas, significantly improves the mixing uniformity, and inhibits the formation of agglomerates.

[0036] The working principle of the above embodiment is as follows: When the drive motor 2 starts, it drives the first rotating shaft 301 to rotate around the axis. The first rotating shaft 301 drives the four-bladed turbine propeller 302 to rotate at high speed, forming a radial shear flow in the mixing tank 1 to crush and disperse the high-viscosity material. At the same time, through the meshing transmission of the first bevel gear 303 and the third bevel gear 7, the power is transmitted to the third bevel gear 7 and drives the second rotating shaft 401 to rotate in the opposite direction. The reverse rotation of the second rotating shaft 401 causes the spiral blade 403 to generate spiral lift, which conveys the material at the bottom upwards, forming an axial circulation. Then, the synergistic effect of the four-bladed turbine propeller 302 and the spiral blade 403 forces the material to rotate in the opposite direction. A bidirectional vortex is formed inside the mixing tank 1 to eliminate mixing dead zones. At this time, when the first scraper 306 rotates with the first rotating shaft 301, its arc surface closely adheres to the inner wall of the mixing tank 1 to scrape off residual materials, and the inclined surface disturbs the boundary layer to enhance fluidity. At the same time, the second scraper 407 moves in the opposite direction with the second rotating shaft 401, and its arc surface and inclined surface cooperate with the movement trajectory of the first scraper 306 to further break up the accumulation of materials at the bottom. Afterward, the heating ring 11 heats the materials through the command of the controller 12, and dynamically adjusts the heating power in combination with the real-time temperature feedback of the temperature sensor 13 to maintain a constant temperature environment. When the mixing is completed, the solenoid valve 16 controls the opening and closing of the discharge pipe 15 to discharge the materials.
