Description

Technical Field

[0001] This utility model relates to the field of casein acidification technology, and more specifically, to a casein dual-paddle acidification device. Background Technology

[0002] Casein is a phosphorus- and calcium-bound protein with wide applications in food, pharmaceuticals, and chemicals. For example, in the food industry, it is often used as an emulsifier and thickener, playing a crucial role in improving product quality and stability. Acidification is a key step in the production and processing of casein. By adding specific acids to casein, its protein structure and properties can be altered to meet the requirements of subsequent applications, such as promoting precipitation and aggregation, thus facilitating subsequent separation and purification.

[0003] Various devices exist on the market for acidifying casein, most of which employ traditional stirring methods to mix the acid and casein. Common structures typically consist of a simple tank and a stirring paddle. The paddle is usually a single-shaft structure, mixing the materials in the tank only through simple rotation. However, due to the limited stirring method, good mixing is often only achieved in localized areas, leading to significant differences in the degree of mixing at different locations within the tank. For example, areas near the paddle are relatively well-mixed, while corners and bottoms away from the paddle are prone to uneven mixing of acid and casein. Therefore, we propose a dual-paddle acidification device for casein. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a casein dual-paddle acid addition device to solve the current technical problem that the degree of mixing of materials in different positions in the tank is often significantly different.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a casein dual-paddle acid addition device, including a mounting frame and a mixing tank fixedly installed inside it, a casein feed pipe and an acid addition pipe fixedly installed on the top of the mixing tank, a discharge pipe fixedly installed on the bottom of the mounting frame, a stirring mechanism and an auxiliary mechanism are provided inside the mixing tank;

[0006] The stirring mechanism includes a gear ring fixedly installed on the inner wall of the stirring tank, and a gear meshing with the gear ring for driving a stirring rod to revolve around the axis of the stirring tank and rotate on its own axis. The surface of the stirring rod is provided with a honeycomb-shaped array of through holes.

[0007] The auxiliary mechanism includes a fixed cylinder fixedly installed at the bottom of the mixing tank, and upper, middle and lower wave plates fixedly installed from top to bottom on the inner wall of the fixed cylinder. Each wave plate has a continuous peak and trough curved surface, and the inclination angle increases layer by layer.

[0008] Preferably, the stirring mechanism includes a motor, which is fixedly installed on the top of the stirring tank. A stirring rod two is fixedly installed at the output end of the motor. A spiral blade is fixedly installed at the bottom of the stirring rod two. A fixing frame is fixedly installed on the outside of the stirring rod two. The gear is rotatably installed inside the fixing frame through a bearing.

[0009] Preferably, the fixed cylinder is fixedly installed on the inner side of the bottom of the mounting frame and above the discharge pipe, and the bottom of the fixed cylinder has symmetrical inlet ports on both sides.

[0010] Preferably, one surface of the stirring rod is provided with a honeycomb-shaped through-hole array, the axis of the through-hole is perpendicular to the axis of the stirring rod, and the edge of the honeycomb-shaped through-hole forms a radial jet under the action of centrifugal force to inhibit material adhesion.

[0011] Preferably, the bottom corrugated plate is a small-angle guide plate for material diversion, convergence and smooth ascent, the middle corrugated plate is a medium-angle guide plate for enhancing the vertical velocity and horizontal turbulence of the material, and the top corrugated plate is a large-angle guide plate for material impact, deflection and acceleration during descent.

[0012] Preferably, the spiral blades are coaxially fixed with the stirring rod, lifting the material at the bottom of the tank to the top when the motor rotates forward, and guiding the material to the discharge pipe when it rotates in reverse.

[0013] Preferably, the inlet of the discharge pipe is located in the middle of the bottom of the mixing tank, and the inlet direction is directly opposite to the material pushing trajectory when the spiral blades reverse.

[0014] Preferably, the spiral blades are located inside the fixed cylinder, and an upward conveying channel is formed between the feed inlet at the bottom of the fixed cylinder and the spiral blades.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a stirring mechanism with spiral blades coaxially fixed to the stirring rod. The spiral blades effectively lift the material from the bottom of the tank to the top, ensuring that the material settled at the bottom can also fully participate in the mixing process, thus improving the utilization rate of materials and the overall mixing efficiency. During the stirring process, the honeycomb-shaped through-holes on the surface of the stirring rod form a radial jet under the action of centrifugal force. This jet breaks the conventional flow state of the material, effectively avoiding the problem of uneven local mixing in traditional equipment, ensuring that the material in the entire mixing tank can achieve a uniform mixing state, improving the quality stability of casein products, and solving the problem of large differences in the degree of mixing of materials in different positions in the tank.

[0017] 2. This utility model also incorporates an auxiliary mechanism in which the inner wall of the fixed cylinder is equipped with upper, middle, and lower corrugated plates with progressively increasing inclination angles. During the mixing stage, each layer of corrugated plates, based on its different inclination angles, guides and disturbs the material to varying degrees, causing the material to continuously divert, converge, and swirl as it rises, gradually enhancing the mixing effect and further improving the uniformity of the mixing between the acid and casein.

[0024] like Figures 1 to 5As shown, the present invention relates to a casein double-paddle acid addition device, which includes a mounting frame 1 and a mixing tank 4 fixedly installed inside it. A casein feed pipe 5 and an acid addition pipe 6 are fixedly installed on the top of the mixing tank 4, and a discharge pipe 7 is fixedly installed on the bottom of the mounting frame 1. A stirring mechanism 2 is provided inside the mixing tank 4, and an auxiliary mechanism 3 is provided inside the mixing tank 4.

[0025] The stirring mechanism 2 includes a toothed ring 27 fixedly installed on the inner wall of the stirring tank 4, and a gear 23 meshing with the toothed ring 27 for driving the stirring rod 24 to revolve around the axis of the stirring tank 4 and rotate on its own axis. The surface of the stirring rod 24 is provided with a honeycomb-shaped through hole array.

[0026] The auxiliary mechanism 3 includes a fixed cylinder 31 fixedly installed at the bottom of the mixing tank 4, and upper corrugated plates 32, middle corrugated plates 33 and bottom corrugated plates 34 fixedly installed from top to bottom on the inner wall of the fixed cylinder 31. Each corrugated plate has a continuous peak and trough curved surface, and the inclination angle increases layer by layer. In this invention, the spiral blades 26 in the mixing mechanism 2 are coaxially fixed with the stirring rod 25. The spiral blades 26 can effectively lift the material at the bottom of the tank to the top, ensuring that the material settled at the bottom can also fully participate in the mixing process, improving the utilization rate of materials and the overall mixing efficiency. During the mixing process, the honeycomb-shaped through holes on the surface of the stirring rod 24 form a radial jet under the action of centrifugal force. This jet can break the conventional flow state of materials, effectively avoiding the problem of uneven local mixing in traditional equipment, ensuring that the materials in the entire mixing tank 4 can achieve a uniform mixing state, improving the quality stability of casein products, and solving the problem of large differences in the degree of mixing of materials in different positions in the tank.

[0027] Furthermore, the stirring mechanism 2 includes a motor 21, which is fixedly installed on the top of the mixing tank 4. A stirring rod 25 is fixedly installed at the output end of the motor 21. A spiral blade 26 is fixedly installed at the bottom of the stirring rod 25. A fixed frame 22 is fixedly installed on the outside of the stirring rod 25. A gear 23 is rotatably installed inside the fixed frame 22 through a bearing. The motor 21 synchronously drives the central stirring rod 25 and the planetary stirring rod 24, simplifying the transmission structure. The spiral blade 26 realizes the dual functions of vertical material conveying and discharge guidance, solving the problem of material sedimentation at the bottom.

[0028] Furthermore, the fixed cylinder 31 is fixedly installed on the inner side of the bottom of the mounting frame 1 and above the discharge pipe 7. The fixed cylinder 31 has symmetrical feed ports on both sides of the bottom. The bidirectional feed port design improves the material capture efficiency at the bottom. Combined with the fixed cylinder 31, it guides the material to flow in a directional manner and avoids mixing dead zones.

[0029] Furthermore, the surface of the stirring rod 24 is provided with a honeycomb-shaped through-hole array, with the through-hole axis perpendicular to the axis of the stirring rod 24. The edge of the honeycomb-shaped through-hole forms a radial jet under the action of centrifugal force, which inhibits material adhesion. The jet effect automatically peels off the material adhering to the surface of the stirring rod, preventing agglomeration and ensuring continuous and efficient mixing.

[0030] Furthermore, the bottom wave plate 34 is a small-angle guide plate, used for material diversion, convergence, and gentle ascent; the middle wave plate 33 is a medium-angle guide plate, used to enhance the vertical velocity and horizontal turbulence of the material; and the top wave plate 32 is a large-angle guide plate, used for material impact, deflection, and acceleration during descent. During the mixing stage, each wave plate, according to its different angles, exerts different degrees of guidance and disturbance on the material, causing the material to continuously divert, converge, and swirl during its ascent, gradually enhancing the mixing effect.

[0031] Furthermore, the spiral blade 26 is coaxially fixed with the stirring rod 25. When the motor 21 rotates forward, it lifts the material at the bottom of the tank to the top, and when it rotates in reverse, it guides the material to the discharge pipe 7. The single-component bidirectional function design enables material circulation and enhanced mixing when rotating forward, and guides the material to the discharge pipe in reverse to avoid the risk of blockage.

[0032] Furthermore, the inlet of the discharge pipe 7 is located at the bottom center of the mixing tank 4, and the inlet direction is directly opposite to the material pushing trajectory when the spiral blade 26 reverses.

[0033] Furthermore, the spiral blade 26 is located inside the fixed cylinder 31, and an upward conveying channel is formed between the feed inlet at the bottom of the fixed cylinder 31 and the spiral blade 26. The fixed cylinder 31 constrains the material to flow directionally along the spiral blade 26, forming a forced circulation path and eliminating sedimentation at the bottom of the tank.

[0034] Working Principle: This embodiment provides a casein dual-paddle acid addition device. In use, casein and acid are added into the mixing tank 4 through the casein feed pipe 5 and the acid addition pipe 6, respectively. The motor 21 is started, and the output end of the motor 21 drives the second stirring rod 25 to rotate. At the same time, the second stirring rod 25 drives the fixed frame 22 to rotate, thereby causing the gear 23 to rotate inside the gear ring 27. The first stirring rod 24, which is fixedly installed at the bottom of the gear 23, rotates around the axis of the mixing tank 4. The surface of the first stirring rod 24 has honeycomb grooves. When the material comes into contact with the edge of the channel, the fluid in the channel flows out quickly due to centrifugal force, forming a "jet cleaning" effect, peeling off the material adhesion layer around the channel, and thus stirring the casein and acid inside the mixing tank 4. At the same time as the second stirring rod 25 rotates, the spiral blade 26 also rotates, conveying the mixture entering from the feed port at the bottom of the fixed cylinder 31 upwards, and bringing the mixture from the bottom into the top of the mixing tank 4.

[0035] The mixture passes sequentially through the bottom corrugated plate 34, the middle corrugated plate 33, and the top corrugated plate 32. First, it passes through the bottom corrugated plate 34, where the mixture, propelled by stirring, contacts the plate. Its small inclination angle causes the material to be gently dispersed and converged by the crests and troughs, initially dispersing the acid and achieving a smooth mixture. Simultaneously, this inclination angle guides the material slowly upwards, smoothly transitioning to the middle corrugated plate 33. The material flows from the bottom to the middle layer, where the medium inclination angle provides a stronger force, accelerating its vertical ascent and making horizontal dispersion and swirling more pronounced, further homogenizing the mixture with the acid. Then, this inclination angle pushes the material upwards to the top corrugated plate 32. Upon reaching the top corrugated plate 32, the large inclination angle causes the material to collide with the crests and fall rapidly, quickly changing its flow direction. This prevents material accumulation at the top and achieves fine mixing during the descent, ultimately resulting in a high-quality, homogeneous mixture.

[0036] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
