Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of stirring tanks, in particular, to a stirring device for dairy product processing. BACKGROUND

[0002] In the process of dairy product processing, a stirring device is used to stir the dairy product evenly or to stir the dairy product and the required additives evenly. For example, in the process of stirring milk, the stirring device brings air into the milk. With the continuous stirring, the air is continuously sheared and dispersed into small bubbles and evenly distributed in the milk. At the same time, the milk is stirred violently, 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 action. The fat and protein in the milk can reduce the surface tension of the liquid. During stirring, these components will adsorb and arrange on the gas-liquid interface to form a protective film, which hinders the coalescence and rupture of the bubbles, so that the bubbles can exist stably and accumulate to form a large number of bubbles. The proteins in the milk, such as casein and whey protein, have certain foaming properties. Under the mechanical action of stirring, the protein molecules denature and stretch, and their hydrophobic groups are exposed to the air to form bubbles, while the hydrophilic groups remain in the water, making the bubbles stable and not easy to break, resulting in an increase in the number of bubbles. The bubbles will carry floating dregs, which need to be removed in time.

[0003] In the prior art, most stirring devices are provided with a scraper that rotates with the stirring rod at the upper position of the stirring rod, which is used to remove the floating dregs when there are too many floating dregs. However, these substances will fall into the milk again, affecting the final quality of the milk. SUMMARY

DETAILED DESCRIPTION

[0038] The application will be further described below in conjunction with the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not to be used as limitations.

[0039] For the purpose of clarity, only the parts of the apparatus that are pertinent to the application are shown in the drawings, and they do not represent the actual structure of the product. In addition, for the purpose of simplicity and easy understanding, in some of the drawings, only one of the parts having the same structure or function is shown schematically, or only one of them is labeled. In this document, "one" means not only "only one", but also "more than one", and "several" includes "two" and "more than two".

[0040] In this document, it should be noted that unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0041] In the application, unless otherwise explicitly specified and limited, "on" or "under" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "on" of the first feature to the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. "Under", "below" and "under" of the first feature to the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is less than that of the second feature.

[0042] In the description of the embodiments, the terms "up", "down", "left", "right", and other orientation or position relationships are based on the orientation or position relationships shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the application.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0044] As Figures 1-8As shown in the figure, it shows a stirring device for dairy product processing of the present application, first of all, it should be pointed out that the stirring device is only suitable for stirring the liquid dairy product with low viscosity, and is not suitable for stirring the liquid dairy product with high viscosity. The tank body 1 in the device is a cylindrical container, the tank body 1 has a cover plate at the top, the cover plate can be opened to add materials into the tank body 1, the bottom of the tank body 1 is a sharp cone, and a discharge pipe is arranged at the bottom of the tank body 1 for discharging the stirred dairy product.

[0045] A stirring rod 2 is vertically arranged in the tank body 1 along the axial direction, the stirring rod 2 can be driven to rotate by the driving motor at the top, the stirring rod 2 adopts the existing rod body structure commonly used for liquid, and the stirring blade can also adopt the existing common paddle structure. The structure and shape of the stirring rod 2 and the stirring blade will not be described in detail here.

[0046] Specifically, a track seat 3 is fixedly installed on the inner wall of the tank body 1 along the axial direction, the track is used to provide a moving space for the up-and-down movement of the collection box 4, and the track seat 3 is in a long strip shape. It can be understood that, because the collection box 4 is located above the liquid surface, the track seat 3 is also located above the liquid surface, so that the interception rate of the track seat 3 on the floating scum and dregs can be reduced.

[0047] The collection box 4 is a long strip-shaped rectangular box body, one end of the collection box 4 is provided with a sliding block, the sliding block can be embedded into the groove of the track seat 3 to realize the sliding along the axial direction of the tank body 1. The collection box 4 is placed on the liquid surface of the dairy product, and when the liquid surface is static, the collection box 4 is parallel to the liquid surface. If the stirring rod 2 stirs in one direction, the scraping block 5 is installed on the liquid-facing surface of the collection box 4. Specifically, the scraping block 5 is made of light and corrosion-resistant material, and is installed on one side of the collection box 4 through a hinge shaft, has a certain buoyancy, can freely swing with the height of the liquid surface, and is always close to the liquid surface. However, it is found in actual use that, since the scraping block 5 is directly located on the liquid-facing surface, part of the scraping block 5 is difficult to be always located on the liquid surface under the scouring of the liquid. However, since the scraping block 5 is abutted with the collection box 4 on the bottom surface, only the tip of the scraping block 5 is located below the liquid surface, and most of the scraping block 5 is located above the liquid surface, so the collection of the floating scum and dregs is not affected.

[0048] The negative pressure adsorber 601 in the negative pressure adsorption accessory 6 is installed outside the side wall of the tank body 1, is connected with the negative pressure main pipe 602 in the tank body 1 through a pipeline, one end of the hose 603 is connected with the negative pressure main pipe 602, and the other end is suspended above the collection box 4.

[0049] For example, as shown in the figure, Figure 2As shown, during operation, the stirring rod 2 is activated to stir the liquid dairy product in the tank 1, generating a large amount of bubbles and froth. The scraper block 5, floating on the liquid surface, swings with the fluctuations of the liquid level, scraping the froth from the liquid surface and pushing it into the collection box 4. When froth accumulates in the collection box 4, the negative pressure absorber 601 draws the froth from the collection box 4 through the hose 603 and discharges it from the tank 1.

[0050] Compared with the existing technology, this solution can effectively collect the floating foam on the liquid surface through the slidable collection box 4 and the swingable scraper block 5, preventing the floating foam from falling into the dairy product again and affecting the quality; the setting of the negative pressure adsorption member 6 can promptly absorb the floating foam in the collection box 4, ensuring the collection effect and improving the processing quality of the dairy product.

[0051] In some examples, a brush roller 7 is rotatably disposed in the collection box 4 via a bearing, and the axial direction of the brush roller 7 is parallel to the length direction of the collection box 4. A plurality of bristle strips 701 are provided on the surface of the brush roller 7. These bristle strips 701 are closely arranged on the outside of the brush roller 7 in a spiral path, and the bristles are made of soft material.

[0052] For example, Figure 3 and Figure 4 As shown, after scraping block 5 scrapes the scum into collection box 4, the scum contacts bristle strips 701 on brush roller 7. Brush strips 701, with their absorbent properties, adhere the scum to the surface of brush roller 7. As brush roller 7 slowly rotates, the scum is continuously transported to a suitable location within collection box 4, facilitating subsequent negative pressure adsorption. The arrangement of brush roller 7 and bristle strips 701 further adsorbs and organizes scum within collection box 4, preventing uneven accumulation of scum within the collection box 4, improving the efficiency and effectiveness of negative pressure adsorption, and reducing scum residue.

[0053] In some examples, the negative pressure absorber 601 is a commonly used industrial vacuum pump, fixedly mounted on the side wall of the tank 1. The negative pressure manifold 602 is a rigid pipe running along the inner wall of the tank 1 and connected to the negative pressure absorber 601 via a flange. The hose 603 is a flexible rubber tube, one end of which is connected to the negative pressure manifold 602 and the other end is fixed to the movable cover 8 and positioned directly above the brush roller 7. The dirt collection box 604 is mounted on the outer wall of the tank 1 and connected to the negative pressure absorber 601 via a pipe, used to store adsorbed scum.

[0054] For example, Figure 3 As shown, the negative pressure absorber 601 is activated, and under the action of negative pressure, the hose 603 generates suction. Scum adhering to the brush roller 7 is sucked in by the suction of the hose 603, passes through the negative pressure main pipe 602, and ultimately enters the collection box 604 for storage, thus completely removing the scum. It should be noted that scum on the scraper block 5 is also affected by the negative pressure absorber 601 and quickly enters the collection box 4.

[0055] Through the coordinated work of the negative pressure adsorber 601, the negative pressure main pipe 602, the hose 603 and the dirt collecting 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 degree of automation and cleanliness of dairy processing.

[0056] In some examples, a slot 902 is defined at the top of the collection box 4 to fit with the movable cover 8, and the movable cover 8 can slide within the slot 902. The end of the hose 603 located above the brush roller 7 is fixedly mounted on the movable cover 8, and the sliding of the movable cover 8 can drive the hose 603 to reciprocate along the axial direction of the brush roller 7.

[0057] For example, Figure 4 and Figure 5 As shown, when absorbing scum from the brush roller 7, the movable cover plate 8, under the action of an external force, such as the electric push rod 17 or the sleeve 91 mentioned later, performs reciprocating linear motion along the axial direction of the brush roller 7, thereby driving the hose 603 to move back and forth above the brush roller 7, so that the hose 603 can adhere to various parts of the brush roller 7 to ensure that the scum is completely removed. The movable cover plate 8 drives the hose 603 to move back and forth, expanding the suction range of the hose 603, improving the comprehensiveness of the suction of scum on the brush roller 7, avoiding suction blind spots, and further improving the scum removal effect.

[0058] In some examples, the sleeve 91 is hollow cylindrical and is mounted on the stirring rod 2, and there is a clearance fit between the two, allowing relative sliding. Several floats 901 are circumferentially installed on the bottom of the sleeve 91. The floats 901 are hollow in structure, and the density of the floats 901 is low, which can support the sleeve 91 to float on the liquid surface. The support rod 92 is fixedly mounted on the tank body 1, directly above the collection box 4, and a slide groove 902 is provided in the length direction of the support rod 92. One end of the connecting rod 93 is hinged in the slide groove 902 through a hinge shaft and can slide in the slide groove 902. The other end is hinged to the sleeve 91, and one end of the movable cover plate 8 is hinged to the middle part of the connecting rod 93.

[0059] For example, Figure 6 As shown, as the liquid level changes during stirring, float 901 drives sleeve 91 up and down along stirring rod 2. As sleeve 91 moves, the hinged structure of connecting rod 93 drives movable cover 8 along collection box 4, thereby achieving automatic movement of movable cover 8 and hose 603, enabling them to adapt to the adsorption of brush roller 7 at different liquid levels. The pull-out assembly 9 utilizes the changes in liquid level to drive the movement of movable cover 8, eliminating the need for an additional power device. Its structure is simple and energy-efficient, and it automatically adapts to changes in liquid level, ensuring effective adsorption of brush roller 7 by hose 603, thereby improving the practicality and reliability of the device.

[0060] In some examples, the movable cover plate 8 is fixedly installed with a rack 10 along the length direction, the first bevel gear 12 is rotatably arranged on the collecting box 4 through a bearing, the back side of the first bevel gear 12 is fixedly installed with a gear 11, the gear 11 is engaged with the rack 10. The end surface of the brush roller 7 is fixedly installed with a second bevel gear 13, the second bevel gear 13 is engaged with the first bevel gear 12.

[0061] For example, as shown in Figure 7 When the movable cover plate 8 moves along the collecting box 4 under the driving of the pulling assembly 9, the rack 10 moves with it, the rack 10 is engaged with the gear 11, and the gear 11 is driven to rotate. The gear 11 drives the first bevel gear 12 to rotate, and the first bevel gear 12 drives the brush roller 7 to rotate through the engagement with the second bevel gear 13, so as to realize the automatic rotation of the brush roller 7 and facilitate the collection and arrangement of the scum. Through the transmission structure of the rack 10, the gear 11, the first bevel gear 12 and the second bevel gear 13, the linear motion of the movable cover plate 8 is converted into the rotary motion of the brush roller 7, without the need to separately arrange a power source for driving the brush roller 7 to rotate, which simplifies the structure of the device and realizes the linkage between the components, thereby improving the working efficiency of the device.

[0062] In some examples, the top surface of the scraping block 5 is a smooth inclined surface inclined to the direction of the collecting box 4, the inclination angle of the inclined surface is 30°, and the inclined surface is polished to be smooth. The scraping block 5 is connected with an extension 14 on one side inside the collecting box 4, the extension 14 is in the form of a thin plate and is used to prevent the scum from leaking out from the joint between the scraping block 5 and the collecting box 4.

[0063] For example, as shown in Figure 4 and Figure 6 When the scraping block 5 swings to scrape the scum, the scum on the liquid surface is pushed into the collecting box 4 along the smooth inclined surface of the scraping block 5, and due to the guiding effect of the inclined surface, the scum can smoothly enter the collecting box 4, reducing the residue. The extension 14 plays a shielding role to prevent the scum from overflowing from the gap. The smooth inclined surface of the scraping block 5 is conducive to the scraping and pushing of the scum, improving the scraping efficiency; and the arrangement of the extension 14 ensures the sealing of the collecting box 4, avoiding the leakage of the scum and ensuring the scum collection effect.

[0064] In some examples, the side of the collecting box 4 away from the scraping block 5 is provided with a plurality of through grooves 401, which are used to drain the dairy liquid in the scum.

[0065] For example, as shown in Figure 4 When the scum is scraped into the collecting box 4, the dairy liquid containing oil therein flows back to the dairy in the tank 1 under the action of gravity through the through grooves 401, and the scum remains in the collecting box 4, realizing the preliminary separation of the scum and the liquid. The arrangement of the through grooves 401 can effectively separate the dairy liquid in the scum, reduce the waste of the liquid, improve the utilization rate of the dairy, and at the same time, reduce the workload and cost of subsequent processing of the scum.

[0066] 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 structure with 6 protrusions 16 arranged at circumferential intervals on its edge. Adjacent protrusions 16 are arranged in opposite directions. The protrusions 16 are triangular plates and are welded vertically to the stirring disc 15.

[0067] For example, Figure 2 As shown, when the stirring rod 2 drives the stirring disc 15 to rotate, the protrusions 16 rotate accordingly. Because adjacent protrusions 16 rotate in opposite directions, the dairy product is subjected to stirring forces in different directions during rotation, thereby achieving a more effective stirring effect. The structural design of the stirring disc 15 and protrusions 16 can enhance the stirring effect, ensure more uniform stirring of the dairy product, and improve the processing quality of the dairy product. At the same time, the stirring forces in different directions help reduce the generation of bubbles and reduce the amount of froth.

[0068] In some examples, an electric push rod 17 is provided on the support rod 92 , and the movable end of the electric push rod 17 is hinged to the end of the connecting rod 93 located in the slide groove 902 . The electric push rod 17 is used to push one end of the connecting rod 93 to move along the slide groove 902 .

[0069] For example, Figure 3 and Figure 6 As shown, when the position of the movable cover 8 and the hose 603 needs to be adjusted to better adsorb the brush roller 7 or to be used under special working conditions, the electric push rod 17 is started, and the movable end of the electric push rod 17 is extended and retracted, pushing one end of the connecting rod 93 to move along the slide 902, and then driving the movable cover 8 to move through the connecting rod 93 to achieve precise position adjustment. The setting of the electric push rod 17 provides an additional power adjustment method for the movement of the movable cover 8 and the hose 603, which can accurately control their position according to actual working requirements, enhance the flexibility and adaptability of the device, and can meet the dairy processing needs under different working conditions.
