Description

Technical Field

[0001] The present invention relates to the technical field of material filtration and separation, specifically to a milk material anti-blocking filtration device and its application in the preparation of rose yogurt. Background Art

[0002] Rose yogurt has won the favor of the majority of consumers with its rich aroma, mellow, sweet and sour taste, smooth and delicate texture, and the advantages of being rich in probiotics. Its preparation process is relatively simple, and the main raw materials are yogurt and rose petals or rose extracts, among which the quality of yogurt directly determines the final quality of rose yogurt.

[0003] During the production process of yogurt, due to the influence of various factors such as whey protein concentration and fermentation temperature, aggregation phenomena may occur inside the yogurt, forming large particulate matter. When this yogurt with large particles is further processed into rose yogurt, it will significantly affect the mixing effect between raw materials and the taste experience of the product.

[0004] To address this problem, the currently common treatment method is to filter the yogurt before mixing the raw materials to remove the large particulate matter therein. Usually, a sieve mesh with a fixed mesh number is selected for filtration. However, during the filtration process, over time, the large particulate matter in the yogurt will gradually adhere to the sieve mesh, resulting in a decrease in filtration efficiency. At the same time, the pressure on the feed side will rise accordingly, which increases the risk of large particulate matter passing through the sieve mesh, and may eventually cause the mesh number of the sieve mesh to become larger, ultimately leading to damage to the sieve mesh. To avoid this situation, it is usually necessary to regularly remove the sieve mesh for cleaning, but this will undoubtedly cause the equipment to stop, thereby affecting the entire production process.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0029] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a milk material anti-blocking filtering device includes: a pipe housing 1, a switching structure, a pump pressure assembly, a transverse movement structure, and a support plate 27; There are two groups of the pipe housing 1, and a filter element is detachably installed in the pipe housing 1. Specifically, a spiral guiding piece 4 is provided in the pipe housing 1, and a convex ring 101 is provided at one end of the pipe housing 1, and the filter element can be inserted into the convex ring 101; The filter element includes a hollow middle pipe 7, through holes are provided on the circumferential side wall of the middle pipe 7, and a screen 8 is sleeved on the middle pipe 7.

[0030] During the operation of the milk material screening device, first, the screen 8 is sleeved on the middle pipe 7, and then one end of the middle pipe 7 is accurately aligned with the convex ring 101 and inserted, and the other end of the middle pipe 7 is hermetically connected to the pipe housing 1 by means of a flange. During this process, an annular cavity is formed between the middle pipe 7 and the screen 8. When the milk material flows into this annular cavity, it can pass through the screen 8 and the through holes and enter the inside of the middle pipe 7, thereby achieving the screening operation, effectively removing large particle substances in the milk material, and significantly improving the dense texture of the subsequent dairy products; at the same time, the ingenious setting of the convex ring 101 ensures good coaxiality between the middle pipe 7 and the pipe housing 1. In this way, after the milk material enters the annular cavity, it can uniformly pass through the screen 8 and the middle pipe 7 from all positions of the annular cavity, greatly improving the screening effect.

[0031] When the milk material enters the annular cavity, it has a tendency to move towards the convex ring 101 by itself. At this time, the spiral guide piece 4 plays a key role, prompting the milk material to generate a certain degree of spiral movement. Under the action of centrifugal force, the large-particle substances in the milk material adhere to the side wall of the pipe housing 1, thereby reducing to a certain extent the blockage problem of the large-particle substances in the milk material to the screen 8 and ensuring the smoothness of the screening process.

[0032] During the process of the milk material flowing through a certain group of pipe housings 1, the screen 8 will inevitably filter out large-particle substances, and these large-particle substances will adhere to the screen 8. At this time, the switching structure intervenes in time to guide the milk material to flow to another group of pipe housings 1. At the same time, with the cooperation of the pump pressure component, the large-particle substances adhering to the screen 8 are separated from the screen 8 and adhere to the inner wall of the pipe housing 1. After the switching structure moves in place, the external cleaning liquid pumping device will pump cleaning liquid into the pipe housing 1. Under the action of the spiral guide piece 4, the cleaning liquid forms a spiral movement in the pipe housing 1, strongly flushing the large-particle substances adhering to the inner wall of the pipe housing 1, reducing the content of large-particle substances in this group of pipe housings 1, thereby restoring the good filtering state of the screen 8 and ensuring the continuous and efficient operation of the entire screening device.

[0033] The optimized milk material screening device not only improves the efficiency and quality of milk material screening, reduces the blockage problem of the screen 8, and extends the service life of the screen 8, but also reduces the maintenance cost of the equipment through an effective cleaning mechanism, provides a more stable and higher-quality guarantee for dairy product production, and helps to improve the automation degree and production efficiency of the entire dairy product production process.

[0034] Please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 The switching structure is connected to the two groups of pipe housings 1, and the switching structure can enable the milk material to flow alternately in the two groups of pipe housings 1; The pipe housing 1 is also provided with a first feed inlet 2 and a second feed inlet 6. The switching structure includes multiple groups of valve body kits. The valve body kits are connected to the first feed inlet 2, the first discharge outlet 3, and the second feed inlet 6. Among them, the valve body kit connecting the first feed inlet 2 and the first discharge outlet 3 is connected by a connecting shaft 12, and the connecting shaft 12 is connected to another group of the valve body structure through a toothed belt 13. One end of the connecting shaft 12 is connected to a drive motor 9 provided on the valve body structure; The tube shell 1 is also provided with a second discharge port 5, the opening and closing of which is controlled by an electronic conduction valve, which can be turned on when compressed gas or cleaning liquid is filled into the tube shell 1. It should be noted that the second feed port 6 and the second discharge port 5 are respectively connected tangentially to the tube shell 1. When the external cleaning liquid is pumped into the tube shell 1, the liquid flow first enters along the tangential direction, forming a strong circular motion inside the tube shell 1, generating a centrifugal force field similar to a vortex. On this basis, the spiral guide plate 4 further optimizes the liquid flow trajectory, converts the simple circular motion into a spiral propulsion motion, and enables the cleaning liquid to efficiently rush to the second discharge port 5 along a spiral path. This composite flow pattern not only enhances the directional mobility of the liquid flow, but also peels off the large particles attached to the inner wall through centrifugal force and entrains them to the discharge port.

[0035] Specifically, the initial centrifugal force generated by the tangential feed port can directly throw the loose particles on the inner wall into the main body of the liquid flow, while the secondary guidance of the spiral blades forms a continuous tangential impact on the stubborn attachments, and the dynamic water pressure generated by the pump pressure can effectively remove the milk stains on the surface of the screen 8 and the tube wall; compared with the traditional straight-through cleaning design, this structure can improve the cleaning efficiency and reduce the residual particles.

[0036] This innovative design enables the device to have both self-cleaning function and long-term filtration performance. In the continuous production process, it can reduce non-production time and extend the replacement cycle of screen 8. The milk material treated by this system can reduce the standard deviation of particle size distribution, which effectively ensures the quality stability of dairy products and the reliability of equipment operation in subsequent homogenization and sterilization processes, especially in the production of high-density dairy products, showing significant process advantages.

[0037] The valve body kit includes an outer shell 10 and a switching member 11 which is sealingly rotatably installed in the outer shell 10 . A flow channel 1101 is provided in the switching member 11 , and the switching member 11 is coaxially and fixedly connected with the connecting shaft 12 .

[0038] It should also be noted that three groups of conduits are configured on the outer shell 10 of each valve body kit. For the valve body kit connected to the first feed port 2, two groups of conduits are respectively connected to the first feed ports 2 of the two tube shells 1, and the other group of conduits is connected to the discharge port of the external milk device. When the switching member 11 rotates, the direction in which the milk enters the tube shell 1 can be changed, and the milk flows to the corresponding tube shell 1 according to the guiding requirements. This design provides a time gap for removing large particles in the other group of tube shells 1, and ensures continuous transportation and filtration of the milk, reduces downtime caused by cleaning, and improves production efficiency.

[0039] In the valve body kit connected to the first discharge port 3, two groups of conduits are connected to the first discharge ports 3 of the two tube shells 1, and the other group of conduits is connected to an external device for receiving filtered milk. The valve body structure switching component 11 is directly connected to the feed port valve body kit switching component 11 via the connecting shaft 12. When the drive motor 9 is started, the two groups of valve body kits operate synchronously to change the flow path of the milk, so that the first feed port 2 and the first discharge port 3 of one group of tube shells 1 are connected, and the other group is blocked.

[0040] The valve body structure connected to the second feed port 6, two sets of conduits are connected to the second feed port 6, and the other set is connected to the external cleaning liquid pumping device, such as Figure 6 As shown, the switching member 11 of the valve body kit is connected to the connecting shaft 12 by a toothed belt 13. When the driving motor 9 is activated, the three groups of valve body kits are activated synchronously to block the first feed port 2 and the first discharge port 3 of one group of tube shells 1, and at the same time, the second feed port 6 of the tube shell 1 is opened to cut off the entry of milk material, and at the same time, the cleaning liquid enters the tube shell 1 in time to perform the cleaning operation, so as to avoid the coagulation of large particles in the tube shell 1 and the inability to be effectively rinsed.

[0041] This setting realizes synchronous control of the opening and closing of the first feed port 2, the first discharge port 3 and the second feed port 6, with theoretically zero delay and high action accuracy, ensuring the accurate flow direction of milk material and cleaning liquid, effectively shortening the production switching time, improving production efficiency and equipment utilization. At the same time, this design reduces the risk of leakage of milk material during the switching process and reduces material loss during the production process.

[0042] See also Figures 7 to 9 The pump pressure assembly is provided with two groups and is respectively connected to the first discharge ports 3 on the two groups of the tube housings 1. The pump pressure assembly is provided with a coaxial wheel set. In detail, the two groups of the tube housings 1 are connected by a connecting plate, and the two groups of the pump pressure assemblies are diagonally arranged on the connecting plate; The pumping assembly includes a pumping cylinder 16 fixedly mounted on the connecting plate, a sealing plug 18 is sealingly and slidably mounted in the pumping cylinder 16, the sealing plug 18 is connected to a connecting plate 19 slidably arranged through the pumping cylinder 16, the connecting plate 19 is slidably connected to the coaxial wheel set, and a first cylindrical spring 20 is sleeved on the connecting plate 19, one end of the first cylindrical spring 20 is connected to the sealing plug 18, and the other end is connected to the inner wall of the pumping cylinder 16; The pumping cylinder 16 is provided with two groups of one-way valves 17 with different conduction directions, and one group of the one-way valves 17 is connected to the first discharge port 3 .

[0043] When the drive motor 9 is started, the transverse movement structure acts accordingly, driving the connecting plate 19 to move, pushing the sealing plug 18 to slide within the pumping cylinder 16, creating a negative pressure environment inside the pumping cylinder 16. At this time, external air quickly rushes into the pumping cylinder 16 through a set of one-way valves 17. Meanwhile, the first cylindrical spring 20 is compressed and stores elastic potential energy.

[0044] After the transverse movement structure reaches the predetermined position, the connecting plate 19 is immediately released. The first cylindrical spring 20 instantly releases the accumulated elastic potential energy, strongly compressing the air inside the pumping cylinder 16. The compressed air, driven by the pressure, is conveyed through another set of one-way valves 17 into the first discharge port 3 whose end has been blocked, and flows along a path opposite to the movement direction of the milk material, advancing from the middle pipe 7 towards the annular cavity.

[0045] It is worth mentioning that the first cylindrical spring 20 has a very high stiffness. This enables it to quickly compress the compressed air into the middle pipe 7 when releasing the elastic potential energy. The instantly increased pressure gives the air a powerful impact force, causing it to spray towards the screen 8. The screen 8 expands outwards under the action of the air pressure. At the same time, the large-particle substances attached to it are pushed open by the airflow impact, detached from the surface of the screen 8, and attached to the inner wall of the pipe housing 1. This process efficiently completes the transfer of large-particle substances from the screen 8 to the inner wall of the pipe housing 1.

[0046] When the subsequent cleaning liquid flushing operation is carried out, these already transferred large-particle substances will be smoothly discharged from the pipe housing 1 through the second discharge port 5 along with the water flow. This not only greatly reduces the risk of blockage of the screen 8, extends the service life of the screen 8, but also ensures that the milk material can always obtain high-quality filtering effects during the subsequent filtering process, effectively improving the quality of dairy products.

[0047] This device innovatively utilizes the mutual conversion of mechanical energy and pneumatic energy to achieve the perfect combination of the self-cleaning function of the screen 8 and the efficient screening operation. By precisely controlling the coordinated actions of the drive motor 9 and the transverse movement structure, it not only improves the production efficiency of the milk material but also reduces the equipment maintenance cost and downtime.

[0048] Please refer to Figure 7 、 Figure 9 The transverse movement structure is connected to the switching member 11. An abutting member 25 adapted to the coaxial wheel set is provided on the transverse movement structure, and an inclined portion 2501 is formed on the abutting member 25; The transverse movement structure includes a connecting shaft 12 connecting two of the valve body kits and a transverse movement member 15 sleeved on the connecting shaft 12. The transverse movement member 15 is slidably connected to a guiding member 14 provided on the connecting plate; A convex shaft 1501 is provided on the inner wall of the transverse moving member 15, and the convex shaft 1501 is slidably connected to a spiral groove 1201 provided on the outer wall of the connecting shaft 12; The transverse moving structure further includes an elastic kit connecting the transverse moving member 15 and the abutting member 25. The elastic kit includes a guiding sleeve 24 fixedly installed on the transverse moving member 15. The guiding sleeve 24 is slidably connected to the abutting member 25, and the guiding sleeve 24 and the abutting member 25 are connected by a second cylindrical spring 26; It should be noted that when the switching member 11 switches the flow direction of the milk material, the rotation direction of the switching member 11 can be referred to Figure 6 and the rotation angle of the switching member 11 during rotation is 270°.

[0049] When the driving motor 9 drives the switching member 11 to rotate, the connected connecting shaft 12 will rotate. At this time, with the cooperation of the convex shaft 1501 and the spiral groove 1201, the transverse moving member 15 can move along the length direction of the connecting shaft 12. The driving motor 9 is a motor that can rotate bidirectionally, so that while it can drive the switching member 11 to rotate repeatedly, it can make the transverse moving member 15 reciprocate along the length direction of the connecting shaft 12. And under the action of the guiding member 14, it can prevent the transverse moving member 15 from rotating following the connecting shaft 12, so that it can move stably.

[0050] When the transverse moving member 15 moves along the length direction of the connecting shaft 12, the abutting member 25 can abut against the coaxial wheel set, and drive the connecting plate 19 to move, so that the first cylindrical spring 20 stores elastic potential energy. When the abutting member 25 moves to a predetermined position, the coaxial wheel set cooperates with the support plate 27, and can separate the coaxial wheel set from the abutting member 25. At this time, the first cylindrical spring 20 releases the elastic potential energy to transport high-pressure gas into the middle pipe 7, and finally realizes the reset of the coaxial wheel set and the connecting plate 19.

[0051] When the connecting shaft 12 rotates in the reverse direction and the transverse moving member 15 moves in the reverse direction, the abutting member 25 will also move in the reverse direction. When the abutting member 25 moves to the initial state, the inclined portion 2501 on the abutting member 25 can abut against the coaxial wheel set. At this time, since the coaxial wheel set is in a static state, under the cooperation of the inclined portion 2501 and the coaxial wheel set, the abutting member 25 can move upward relative to the guiding sleeve 24, stretching the second cylindrical spring 26. After the abutting member 25 moves to the other side of the coaxial wheel set, the second cylindrical spring 26 can release the elastic potential energy and make the abutting member 25 return to the initial state, so that the above process can be repeated during the next movement of the transverse moving member 15, and the above actions can be continuously performed.

[0052] It should be emphasized that the above-mentioned pump pressure assemblies are diagonally arranged on the connecting plate. It can be understood that the ends of the pumping cylinder block 16 with one-way valves 17 face different directions. When the two groups of pumping cylinder blocks 16 transport compressed gas, the moving directions of the sealing plugs 18 and the connecting plates 19 are also different. Moreover, two groups of abutting members 25 are provided on the transverse moving member 15, and the facing directions of the inclined portions 2501 on the two groups of abutting members 25 are opposite. The significance of this setting lies in: When the valve body kit switches the flow direction of the milk material and the transverse moving member 15 moves in a fixed direction, the abutting member 25 on one side thereof can cooperate with the coaxial wheel set, enabling one group of pumping cylinder blocks 16 to draw in air. And when the abutting member 25 on the other side reaches the end of the moving stroke, the inclined portion 2501 on the abutting member 25 can abut against another group of coaxial wheel sets, enabling this group of abutting members 25 to move to the other side of the coaxial wheel set. When the transverse moving member 15 moves in the reverse direction, it can drive another group of pumping cylinder blocks 16 to draw in air. That is, during the reciprocating movement of the transverse moving member 15, it can alternately drive the two groups of pump pressure assemblies to act, so as to alternately transport compressed gas towards the two groups of pipe housings 1, ensuring that when the first feed port 2 and the first discharge port 3 in one group of pipe housings 1 are blocked, compressed gas can be transported towards this group of pipe housings 1, thereby realizing the removal of large-particle substances on the screen 8 in this group of pipe housings 1.

[0053] Based on the above settings, when the valve body kit switches the moving direction of the milk material, the pump pressure assemblies arranged on both sides of the transverse moving member 15 can act alternately and transport compressed gas into the pipe housing 1 where the first feed port 2 and the first discharge port 3 are blocked, realizing the removal of large-particle substances on the corresponding screen 8, achieving the effect of sustainable and stable operation.

[0054] Please refer to Figures 8 to 9 , a chute 1901 is provided at one end of the connecting plate 19 away from the sealing plug 18. The coaxial wheel set includes a weight slider 21 slidably installed in the chute 1901. Coaxial first abutting shafts 22 and second abutting shafts 23 are respectively rotatably installed on both sides of the weight slider 21. The first abutting shaft 22 is adapted to the abutting member 25, and the second abutting shaft 23 is adapted to the support plate 27; The support plate 27 is in rolling cooperation with the second abutting shaft 23 and can be separated from the abutting member 25 after the abutting member 25 drives the coaxial wheel set to move to a predetermined position; A flat surface 2701 and an inclined surface 2702 are formed on the upper end surface of the support plate 27. When the coaxial wheel set moves along the inclined surface 2702, it can roll relative to the abutting member 25.

[0055] In the initial state, the second abutting shaft 23 is in a state of abutting against the flat surface 2701. At this time, the first abutting shaft 22 and the lower end of the abutting member 25 have an overlapping area on the vertical plane, so as to ensure that when the abutting member 25 acts on the first abutting shaft 22, the first abutting shaft 22 can be driven to move, or when the inclined portion 2501 acts on the first abutting shaft 22, the abutting member 25 can move upward, realizing the position switching between the abutting member 25 and the first abutting shaft 22.

[0056] When the transverse moving member 15 drives the abutting member 25 to move, the abutting member 25 can abut against the first abutting shaft 22. At this time, the second abutting shaft 23 can move along the flat surface 2701 to pull the connecting plate 19 and the sealing plug 18 to move. When the abutting member 25 moves to a predetermined position, the second abutting shaft 23 will move along the inclined surface 2702, and the first abutting shaft 22 will slide relative to the abutting member 25. As the abutting member 25 and the first abutting shaft 22 continue to move, the two will be misaligned. Subsequently, the abutting member 25 continues to move, while the first abutting shaft 22 and the second abutting shaft 23 will move in the reverse direction, so that the compressed gas is pumped into the corresponding pipe housing 1. When the abutting member 25 follows the transverse moving member 15 to reset, the inclined portion 2501 on the abutting member 25 will abut against the first abutting shaft 22 again, forcing the abutting member 25 to move upward and reset to the other side of the first abutting shaft 22.

[0057] Through the above settings, it is realized that the first abutting shaft 22 can be separated from the abutting member 25 after moving to a predetermined position, thereby realizing the pumping of compressed gas. And under the support of the support plate 27, it can be ensured that when the inclined portion 2501 abuts against the second abutting shaft 23, the height of the first abutting shaft 22 will not change, so that the abutting member 25 can reset to the other side of the first abutting shaft 22, so that when the abutting member 25 reciprocates, it can periodically drive the first abutting shaft 22 to move, ensuring the stability of compressed gas pumping.

[0058] Specifically, when the abutting member 25 is separated from the first abutting shaft 22, the switching structure does not complete the switching action, that is, before the flow direction of the milk material changes, the compressed gas can enter the corresponding pipe housing 1 prior to the cleaning liquid, so that the large particle substances attached to the screen 8 can be first pushed open to the inner wall of the pipe housing 1 by the compressed gas, and then the cleaning liquid flushes it, avoiding the insufficient cleaning caused by the simultaneous entry of the compressed gas and the cleaning liquid into the pipe housing 1.

[0059] When the compressed gas and the cleaning liquid enter the pipe housing 1 at the same time, the cleaning liquid will affect the flow rate of the compressed gas and cannot push open the large particle substances attached to the screen 8, which will reduce the cleaning effect to a certain extent.

[0060] As an embodiment of the present invention, an application of the milk material anti-blocking filtering device as described in the preparation of rose yogurt is also proposed.
