Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of stirring tanks, and in particular, to a stirring device for dairy product processing. Background Art

[0002] In the processing of dairy products, a stirring device is used to stir the dairy products evenly or to stir the dairy products and the materials to be added evenly. Take milk as an example. During the stirring process of milk, the stirring device will bring air into the milk. As the stirring continues, the air is continuously sheared and dispersed into small bubbles, which are evenly distributed in the milk. At the same time, the milk is violently turned, and the contact area with the air is greatly increased, so that more air can be dissolved in the milk and form bubbles under the subsequent stirring. The fat, protein and other components in the milk will reduce the surface tension of the liquid. During stirring, these components will be adsorbed and arranged on the air-liquid interface to form a protective film, which hinders the merging and rupture of bubbles, so that the bubbles can exist stably and accumulate to form a large number of bubbles. The proteins in milk, such as casein and whey protein, have certain foaming properties. Under the mechanical action of stirring, the protein molecules are denatured and stretched, and their hydrophobic groups are outward, contacting with the air and wrapping the air to form bubbles, while the hydrophilic groups remain in the water, making the bubbles have better stability and not easy to rupture, resulting in an increase in the number of bubbles. The bubbles will carry scum, which needs to be removed in time.

[0003] Currently, many dairy mixing equipment are equipped with special foam treatment mechanisms. Some equipment adopts a top scraper structure, through which the scraper rotates synchronously with the mixing shaft to scrape the foam on the liquid surface to the collection tank; some equipment is equipped with a negative pressure suction device, which uses airflow to suck the foam away from the mixing container. However, these existing technologies still have limitations. For example, when the scraper is stirring at high speed, it is difficult to completely remove the highly viscous foam, and the residual foam may be re-mixed into the milk; the negative pressure suction device has a low efficiency in capturing tiny bubbles, and it is easy to extract part of the liquid milk together, resulting in a waste of raw materials. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present invention provides a stirring device for dairy product processing, which solves the technical problem that most stirring equipment in the prior art is provided with a scraper which rotates with the stirring rod at the upper position of the stirring rod to scrape off foam and scum. When there is a lot of foam and scum, these substances will fall into the milk again and affect the final quality of the milk.

The support rod is located above the collection box, and a chute is opened along the length direction on the support rod; The connecting rod is hinged and slidably arranged in the chute at one end, and hinged to the sleeve at the other end. The middle part of the connecting rod is hinged to the end of the movable cover plate. The connecting rod can swing vertically downward under the drive of the sleeve to drive the movable cover plate to move along the collection box.

[0010] Optionally, a rack extending along the moving direction is arranged below the movable cover plate. A gear meshing with the rack is rotatably connected to the end of the collection box. A first bevel gear coaxially arranged is connected below the gear. A second bevel gear capable of meshing with the first bevel gear is arranged at the outer end of the brush roller.

Detailed implementation manners The following will further elaborate on the present invention in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

[0019] To simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, for components with the same structure or function, only one of them is schematically shown, or only one of them is labeled.

[0020] In this text, it should be noted that unless otherwise clearly specified and defined, the terms "install", "connect", and "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0023] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0024] Such as Figures 1 to 8As shown, it shows a stirring device for dairy product processing according to the present invention. First of all, it should be noted that this stirring device is only applicable to stirring dairy product liquids with low viscosity and is not applicable to stirring dairy product liquids with high milk consistency. The tank body 1 in this device is a cylindrical container. The top of the tank body 1 has a cover plate. By opening the cover plate, materials can be added into the tank body 1. The bottom of the tank body 1 is a sharp cone shape. A discharge pipe is also provided at the bottom of the tank body 1 for discharging the stirred dairy products.

[0025] A stirring rod 2 is vertically arranged along the axis inside the tank body 1. The stirring rod 2 can be driven to rotate by a driving motor at the top. The stirring rod 2 adopts an existing rod body structure commonly used for liquids, and the stirring blades can also adopt an existing common paddle blade structure. Regarding the structural shapes of the stirring rod 2 and the stirring blades, no more details will be elaborated here.

[0026] Specifically, a track seat 3 is fixedly installed along the axis on the inner wall of the tank body 1. The track provides a moving space for the up and down movement of the collection box 4. The track seat 3 is in a long strip shape. It can be understood that since the collection box 4 is located above the liquid level, the track seat 3 is also located above the liquid level, which can reduce the interception rate of the track seat 3 for foam and scum.

[0027] The collection box 4 is a rectangular box body in a long strip shape. One end of the collection box 4 is provided with a slider, which can be embedded into the groove of the track seat 3 to realize sliding along the axis of the tank body 1. The collection box 4 is placed on the dairy product liquid surface. When the liquid surface is stationary, the collection box 4 is parallel to the liquid surface. If the stirring rod 2 stirs in only one direction, the scraping block 5 is installed on the surface of the collection box 4 facing the liquid. Specifically, the scraping block 5 is made of a light material resistant to corrosion by dairy products. It is installed on one side of the collection box 4 through a hinge shaft, has a certain buoyancy, and can swing freely along with the height of the liquid surface, always closely adhering to the liquid surface. However, it is found in actual use that since the scraping block 5 is directly located on the liquid-facing side, under the scouring of the liquid, part of the scraping block 5 is difficult to always be on the liquid surface. However, due to the reason that the bottom surface of the scraping block 5 abuts against the collection box 4, only the tip of the scraping block 5 will be under the liquid surface, and most of the whole will still be on the liquid surface. Therefore, it does not affect the collection of foam and scum.

[0028] The negative pressure adsorber 601 in the negative pressure adsorbing component 6 is installed outside the side wall of the tank body 1 and is connected to the negative pressure main pipe 602 inside the tank body 1 through a pipeline. One end of the flexible hose 603 is connected to the negative pressure main pipe 602, and the other end is suspended above the collection box 4.

[0029] For example, as Figure 2As shown, during operation, the stirring rod 2 is activated to stir the liquid dairy product in the tank body 1, generating a large amount of bubbles and foam during the stirring process. The scraping block 5 floats on the liquid surface and swings as the liquid surface fluctuates. During the swinging process, the foam on the liquid surface is scraped and pushed into the collection box 4. When the collection box 4 accumulates foam, the negative pressure adsorber 601 sucks the foam in the collection box 4 through the hose 603 and discharges it from the tank body 1. Compared with the prior art, in this solution, through the slidable collection box 4 and the swingable scraping block 5, the foam on the liquid surface can be effectively collected, preventing the foam from falling back into the dairy product and affecting its quality; the setting of the negative pressure adsorption component 6 can timely suck away the foam in the collection box 4, ensuring the collection effect and improving the processing quality of the dairy product.

[0030] In some examples, a brush roller 7 is rotatably arranged in the collection box 4 through a bearing. The axial direction of the brush roller 7 is parallel to the length direction of the collection box 4. A plurality of groups of brush strips 701 are arranged on the surface of the brush roller 7. These brush strips 701 are closely arranged on the outside of the brush roller 7 in a spiral path, and the bristles are made of a soft material.

[0031] For example, as Figure 3 and Figure 4 shown, when the scraping block 5 scrapes the foam into the collection box 4, the foam will come into contact with the brush strips 701 on the brush roller 7. The brush strips 701 adhere to the foam on the surface of the brush roller 7 by virtue of their adsorptivity. As the brush roller 7 slowly rotates, the foam is continuously conveyed to a suitable position in the collection box 4, facilitating subsequent negative pressure adsorption. The setting of the brush roller 7 and the brush strips 701 can further adsorb and arrange the foam in the collection box 4, preventing the foam from accumulating unevenly in the collection box 4, improving the efficiency and effect of negative pressure adsorption, and reducing the residue of foam.

[0032] In some examples, the negative pressure adsorber 601 is a commonly used industrial vacuum adsorption pump, which is fixedly installed on the side wall of the tank body 1. The negative pressure main pipe 602 is a rigid pipe, which is arranged along the inner wall of the tank body 1 and is connected to the negative pressure adsorber 601 through a flange. The hose 603 is a flexible rubber pipe, one end of which is connected to the negative pressure main pipe 602, and the other end is fixed on the movable cover plate 8 and is located directly above the brush roller 7. The sewage collection box 604 is installed on the outer wall of the tank body 1 and is connected to the negative pressure adsorber 601 through a pipe for storing the adsorbed scum.

[0033] For example, as Figure 3 shown, when the negative pressure adsorber 601 is turned on, under the action of negative pressure, the hose 603 generates suction. The scum adhered to the brush roller 7 is sucked in under the suction of the hose 603, passes through the negative pressure main pipe 602, and finally enters the sewage collection box 604 for storage, realizing the complete removal of the scum. It should be noted that the scum on the scraping block 5 will also be affected by the negative pressure adsorber 601 and quickly enter the collection box 4.

[0034] Through the collaborative work of the negative pressure adsorber 601, the negative pressure main pipe 602, the hose 603, and the sewage collection box 604, the scum on the brush roller 7 can be efficiently adsorbed and stored, ensuring the cleanliness of the collection box 4 and the brush roller 7, and improving the automation level and cleanliness of dairy product processing.

[0035] In some examples, a chute 902 adapted to the movable cover plate 8 is opened at the top of the collection box 4, and the movable cover plate 8 can slide in the chute 902. The end of the hose 603 located above the brush roller 7 is fixedly installed on the movable cover plate 8, and the sliding of the movable cover plate 8 can drive the hose 603 to reciprocate axially along the brush roller 7.

[0036] For example, as Figure 4 and Figure 5 shown, when adsorbing the scum on the brush roller 7, under the action of external power, such as the action of the electric push rod 17 or the sleeve 91 mentioned later, the movable cover plate 8 makes a reciprocating linear motion along the axis of the brush roller 7, thereby driving the hose 603 to move back and forth above the brush roller 7, enabling the hose 603 to adhere to various parts of the brush roller 7, ensuring that the scum is completely removed. The movable cover plate 8 drives the hose 603 to reciprocate, expanding the adsorption range of the hose 603, improving the comprehensiveness of the adsorption of the scum on the brush roller 7, avoiding the appearance of adsorption dead angles, and further enhancing the scum removal effect.

[0037] In some examples, the sleeve 91 is a hollow cylindrical shape, sleeved on the stirring rod 2, and there is a clearance fit between the two, allowing relative sliding. A number of floating balls 901 are circumferentially installed at the bottom of the sleeve 91. The floating balls 901 adopt a hollow structure, and the density of the floating balls 901 is small, enabling the sleeve 91 to float on the liquid surface. The support rod 92 is fixedly installed on the tank body 1, directly above the collection box 4. A chute 902 is opened in the length direction of the support rod 92. One end of the connecting rod 93 is hinged in the chute 902 through a hinge shaft and can slide in the chute 902, and the other end is hinged on the sleeve 91. One end of the movable cover plate 8 is hinged to the middle of the connecting rod 93.

[0038] For example, as Figure 6 shown, with the change of the liquid level height during the stirring process, the floating balls 901 drive the sleeve 91 to move up and down along the stirring rod 2. When the sleeve 91 moves, through the hinge structure of the connecting rod 93, it drives the movable cover plate 8 to move along the collection box 4, thereby realizing the automatic movement of the movable cover plate 8 and the hose 603, enabling it to adapt to the adsorption work on the brush roller 7 at different liquid level heights. The pulling component 9 drives the movable cover plate 8 to move by using the change of the liquid level height, without the need for an additional power device, with a simple structure and energy saving, and can automatically adapt to the liquid level change, ensuring the effective adsorption of the hose 603 on the brush roller 7, and improving the practicability and reliability of the device.

[0039] In some examples, a rack 10 is fixedly installed along the length direction of the movable cover plate 8. A first bevel gear 1112 is rotatably arranged on the collection box 4 through a bearing. A gear 11 is fixedly installed on the back side of the first bevel gear 1112. The gear 11 meshes with the rack 10. A second bevel gear 1311 is fixedly installed on the end face of the brush roller 7. The second bevel gear 1311 meshes with the first bevel gear 1112.

[0040] For example, as Figure 7 shown, when the movable cover plate 8 moves along the collection box 4 driven by the pulling component 9, the rack 10 moves accordingly. The rack 10 meshes with the gear 11, pushing the gear 11 to rotate. The gear 11 drives the first bevel gear 1112 to rotate. The first bevel gear 1112 then drives the brush roller 7 to rotate through meshing with the second bevel gear 1311, realizing the automatic rotation of the brush roller 7, which is convenient for the collection and sorting of the foam. Through the transmission structure of the rack 10, the gear 11, the first bevel gear 1112 and the second bevel gear 1311, the linear motion of the movable cover plate 8 is converted into the rotational motion of the brush roller 7, eliminating the need to separately set a power source for driving the brush roller 7 to rotate, simplifying the device structure, and at the same time realizing the linkage between components, improving the working efficiency of the device.

[0041] In some examples, the top surface of the scraping block 5 is a smooth inclined surface that slopes towards the collection box 4. The inclination angle of this inclined surface is 30°, and it is polished to be smooth. An extension part 14 is connected to one side inside the collection box 4 of the scraping block 5. The extension part 14 is in the shape of a thin plate and is used to prevent the foam from leaking out from the connection between the scraping block 5 and the collection box 4.

[0042] For example, as Figure 4 and Figure 6 shown, when the scraping block 5 swings to scrape the foam, the foam on the liquid surface is pushed into the collection box 4 along the smooth inclined surface of the scraping block 5. Due to the guiding effect of the inclined surface, the foam can smoothly enter the collection box 4, reducing residue. The extension part 14 plays a role in blocking, preventing the foam from overflowing from the gap. The smooth inclined surface of the scraping block 5 is beneficial to the scraping and pushing of the foam, improving the scraping efficiency; the setting of the extension part 14 ensures the sealing of the collection box 4, avoiding the leakage of the foam and ensuring the foam collection effect.

[0043] In some examples, several through grooves 401 are provided on one side of the collection box 4 away from the scraping block 5. The through grooves 401 are used to discharge the dairy product liquid in the foam.

[0044] For example, as Figure 4As shown, when the foam is scraped into the collection box 4, the oil-containing dairy liquid therein flows back into the dairy product in the tank body 1 through the through groove 401 under the action of gravity, while the foam remains in the collection box 4, achieving the preliminary separation of the foam and the liquid. The setting of the through groove 401 can effectively separate the dairy liquid in the foam, reduce liquid waste, improve the utilization rate of dairy products, and at the same time reduce the workload and cost of subsequent foam treatment.

[0045] In some examples, a stirring disc 15 is fixedly installed at the bottom of the stirring rod 2. The stirring disc 15 is a circular plate-like structure, and 6 convex pieces 16 are circumferentially arranged at intervals at its edge. The arrangement directions of adjacent convex pieces 16 are opposite. The convex piece 16 is a triangular plate and is perpendicularly welded to the stirring disc 15.

[0046] For example, as Figure 2 shown, when the stirring rod 2 drives the stirring disc 15 to rotate, the convex pieces 16 rotate accordingly. Since the directions of adjacent convex pieces 16 are opposite, the dairy product can be subjected to stirring forces in different directions during the rotation process, thereby achieving a more sufficient stirring effect. The structural design of the stirring disc 15 and the convex pieces 16 can enhance the stirring effect, make the dairy product stirring more uniform, improve the processing quality of dairy products, and at the same time the stirring forces in different directions help to reduce the generation of bubbles and reduce the amount of foam generated.

[0047] In some examples, an electric push rod 17 is arranged on the support rod 92. The movable end of the electric push rod 17 is hinged to the end of the connecting rod 93 located in the sliding groove 902. The electric push rod 17 is used to push one end of the connecting rod 93 to move along the sliding groove 902.

[0048] For example, as Figure 3 and Figure 6 shown, when it is necessary to adjust the positions of the movable cover plate 8 and the hose 603 to better adsorb the brush roller 7 or use it under special working conditions, the electric push rod 17 is started. The movable end of the electric push rod 17 expands and contracts, pushing one end of the connecting rod 93 to move along the sliding groove 902, and then driving the movable cover plate 8 to move through the connecting rod 93, achieving precise position adjustment. The setting of the electric push rod 17 provides an additional power adjustment method for the movement of the movable cover plate 8 and the hose 603, can accurately control its position according to the actual working requirements, enhances the flexibility and adaptability of the device, and can meet the dairy product processing requirements under different working conditions.
