Description

Technical Field

[0001] This invention relates to the field of lily dairy processing technology, specifically a heat exchange cooling device and its application in lily dairy production. Background Technology

[0002] Dairy products are renowned for their high calcium content, high-quality protein, vitamins, and various bioactive peptides, serving as the nutritional cornerstone for supporting bone, muscle, and immune health throughout the entire life cycle. From the initial storage of raw milk and pasteurization to post-fermentation ripening, each step of the processing chain requires rapid cooling to lock in nutrients and inhibit the growth of unwanted bacteria.

[0003] However, in these processes, milk proteins, calcium salts, and polysaccharides are prone to flocculation due to changes in pH and temperature, forming visible flocculents. Although this is a normal process phenomenon and does not impair nutritional value, the flocculents adhere and deposit inside the cooler, causing the scaling rate to increase exponentially, the heat exchange efficiency to drop sharply, and energy consumption and cleaning frequency to rise accordingly.

[0004] The traditional solution is to add a mechanical filter with a fixed aperture at the front end of the cooler to trap flocculent matter. However, the flocculents are viscoelastic and can be squeezed and stretched into strips under pump pressure. They force their way through the screen holes and continue to enter the cooling channel, resulting in rapid scaling. In order to maintain production capacity, the factory can only shut down the machine frequently to disassemble and clean the filter, which not only interrupts continuous production but also increases the water, energy and labor costs of CIP (clean-in-line) cleaning. Summary of the Invention

[0005] The purpose of this invention is to provide a heat exchange cooling device and its application in the production of lily dairy products, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A heat exchange cooling device, connected to a plate heat exchanger body, includes:

[0008] A hysteresis tube is installed on the plate heat exchanger body;

[0009] A misalignment sealing assembly is disposed within the hysteresis tube, forming an annular chamber and a cylindrical chamber within the hysteresis tube. The misalignment sealing assembly has a first state and a second state that can be changed by traction. When the misalignment sealing assembly is in the second state, the annular chamber and the cylindrical chamber are in communication.

[0010] A driving element is disposed within the cylindrical cavity, and the driving element is capable of driving the lily milk product entering the cylindrical cavity to rotate;

[0011] The sealing plug is slidably disposed within the annular cavity;

[0012] A drive mechanism is provided, which connects the misaligned sealing assembly and the sealing plug. The drive mechanism is provided with an abutment plate, which cooperates with an abutment wheel provided on the misaligned sealing assembly. After driving the misaligned sealing assembly to switch from the second state to the first state, it can continue to drive the sealing plug to move along the annular cavity.

[0013] As a further aspect of the present invention: the misalignment sealing assembly includes an inner tube disposed inside and coaxial with the hysteresis tube, a sealing ring being slidably installed on the outer wall of the inner tube, and the sealing ring being connected to an elastic retaining structure disposed outside the hysteresis tube;

[0014] The inner walls of the built-in tube and the sealing ring are respectively provided with a first through hole and a second through hole, and the first through hole and the second through hole are compatible.

[0015] The built-in tube is also provided with an annular guide portion, which can guide the flocculent material into the first through hole.

[0016] As a further embodiment of the present invention: the elastic retaining structure includes a connecting rod that is fixedly connected to the sealing ring and passes through the hysteresis tube, a cylindrical spring is sleeved on the connecting rod, one end of the cylindrical spring is connected to the connecting rod, and the other end is connected to the hysteresis tube;

[0017] The elastic retaining structure also includes a sliding rod perpendicular to the connecting rod and slidably connected to one end of the connecting rod away from the sealing ring. One end of the sliding rod is rotatably connected to the abutment wheel, and the other end is connected to the hysteresis tube through a stop kit.

[0018] As a further embodiment of the present invention: the stop kit includes a guide plate disposed on the hysteresis tube, the guide plate being provided with a guide groove, and a convex shaft rotatably connected to the end of the sliding rod away from the abutment wheel being able to roll within the guide groove;

[0019] When the convex shaft is at the upper end of the guide groove, the first through hole coincides with the second through hole.

[0020] As a further embodiment of the present invention: the guide groove includes a vertical groove and an inclined groove disposed on the guide plate. When the drive mechanism is activated, it can drive the sliding rod to move and cause the convex shaft to move sequentially along the vertical groove and the inclined groove.

[0021] As a further embodiment of the present invention: the driving component includes a driving device fixedly mounted on the hysteresis tube and a rotating distributor rotatably mounted inside the hysteresis tube, wherein the output shaft of the driving device is connected to the rotating distributor;

[0022] The rotating distributor includes multiple groups of distributor plates arranged equidistantly around the circumference, the distributor plates being arranged along the radial direction of the hysteresis tube.

[0023] As a further embodiment of the present invention: the driving mechanism includes a linear drive module fixedly installed on the outer wall of the hysteresis tube, the linear drive module being connected to the sealing plug via a connecting arm, and the abutment plate being disposed on the connecting arm;

[0024] The sealing plug is provided with a flexible rubber component, and the height of one end of the flexible rubber component is lower than that of the other end.

[0026] When the convex shaft moves to the end of the inclined groove, the abutting wheel can roll on the vertical surface.

[0027] The application of the heat exchange cooling device described above in the production of lily dairy products.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] By incorporating a hysteresis tube, a staggered sealing assembly, and a driving component, the lily milk product can rotate as it enters the cylindrical chamber. This allows the flocculent material in the lily milk product to adhere to the inner wall of the built-in tube and, under the scouring, creep along the inner wall of the built-in tube, thus entering the annular chamber. This prevents the flocculent material from entering the cooling device, which would cause blockage or rapid scaling of the plate heat exchanger, and extends the service life of the cooling device.

[0030] By using a staggered sealing assembly, a sealing plug, and a driving mechanism, the annular chamber is first separated from the cylindrical chamber when the flocculent material in the annular chamber is squeezed. This prevents the flocculent material from returning to the cylindrical chamber during the squeezing process. Furthermore, the flexible rubber component allows for the directional squeezing of the flocculent material at the bottom of the annular chamber, thereby discharging more flocculent material, improving the removal rate, and reducing the risk of caking and bacterial growth.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0043] The present invention aims to provide a cooling device for processing lily dairy products, as detailed below:

[0044] Please see Figures 1-9 In this embodiment of the invention, a heat exchange cooling device is connected to a plate heat exchanger body. The plate heat exchanger body includes two sets of side plates 1 arranged symmetrically. The two sets of side plates 1 are connected by a connecting rod 3, and multiple sets of liquid cooling plates 2 are arranged between the two sets of side plates 1.

[0045] Includes: hysteresis tube 5, misalignment sealing assembly, drive component, sealing plug 19, and drive mechanism.

[0046] The hysteresis tube 5 is connected to the liquid cooling plate 2 via a connecting pipe 4, and the bottom of the hysteresis tube 5 is provided with a connecting pipe for connecting to an external collection device.

[0047] The misaligned sealing assembly is disposed within the hysteresis tube 5, forming an annular chamber 7 and a cylindrical chamber within the hysteresis tube 5. The misaligned sealing assembly has a first state and a second state that can be changed by traction. When the misaligned sealing assembly is in the second state, the annular chamber 7 is connected to the cylindrical chamber. When the misaligned sealing assembly is in the first state, the annular chamber 7 and the cylindrical chamber are isolated, so that the annular chamber 7 forms an independent cavity structure. This allows the flocculent material in the annular chamber 7 to be squeezed out when the sealing plug 19 moves, preventing the flocculent material from being compressed and returning to the cylindrical chamber during the squeezing process.

[0048] The misalignment sealing assembly includes an inner tube 6 disposed within and coaxial with the hysteresis tube 5. A sealing ring 8 is slidably mounted on the outer wall of the inner tube 6. The sealing ring 8 is connected to an elastic retaining structure disposed outside the hysteresis tube 5. The elastic retaining structure includes a connecting rod 11 fixedly connected to the sealing ring 8 and passing through the hysteresis tube 5. A cylindrical spring 16 is sleeved on the connecting rod 11. One end of the cylindrical spring 16 is connected to the connecting rod 11, and the other end is connected to the hysteresis tube 5.

[0049] The elastic retaining structure also includes a sliding rod 12 that is perpendicular to the connecting rod 11 and slidably connected to one end of the connecting rod 11 away from the sealing ring 8. One end of the sliding rod 12 is rotatably connected to the abutting wheel 13, and the other end is connected to the hysteresis tube 5 through a stop kit.

[0050] The inner walls of the built-in tube 6 and the sealing ring 8 are respectively provided with a first through hole 601 and a second through hole 801, and the first through hole 601 and the second through hole 801 are compatible.

[0051] The built-in tube 6 is also provided with an annular guide part 602, which can guide the flocculent material into the first through hole 601.

[0052] In this embodiment, initially, the cylindrical spring 16 is compressed. The force exerted by the cylindrical spring 16 on the connecting rod 11 causes the sealing ring 8 to move upwards. In conjunction with the stop assembly, the sealing ring 8 remains relatively stationary. In this state, the second through hole 801 on the sealing ring 8 completely overlaps with the first through hole 601 on the internal tube 6, i.e., the aforementioned second state. In this state, when the driving component actuates and rotates the lily milk product entering the cylindrical chamber, the lily milk product can follow suit with circular motion. Simultaneously, the flocculent material in the lily milk product, due to its mass... The larger quantity allows it to adhere to the inner wall of the built-in tube 6. At the same time, the lily milk is in a state of movement along the cylindrical cavity, which makes the lily milk have a certain flushing effect on the flocculent material attached to the built-in tube 6. At this time, the flocculent material will not only adhere to the inner wall of the built-in tube 6, but also can peristalse downward. When it peristalses to the position of the first through hole 601, the flocculent material can pass through the first through hole 601 and the second through hole 801 and enter the annular cavity 7, thereby removing the flocculent material and preventing it from entering the cooling device with the lily milk, causing the liquid cooling plate 2 to be blocked or causing the liquid cooling plate 2 to scale at a faster rate.

[0053] After the lily milk flows through the cylindrical chamber for a predetermined time, the drive mechanism can be activated and drive the sealing ring 8 to move downward. At this time, the second through hole 801 on the sealing ring 8 can be misaligned with the first through hole 601. When the two are completely misaligned, the annular chamber 7 and the cylindrical chamber are completely separated. At this time, the drive mechanism continues to drive the sealing plug 19 to move, which can squeeze the flocculent material in the annular chamber 7 and discharge the flocculent material from the bottom connecting pipe of the hysteresis tube 5. When the sealing plug 19 is reset, it can drive the sealing ring 8 to move in the opposite direction, thereby realizing the reconnection between the annular chamber 7 and the cylindrical chamber.

[0054] It should be noted that when the annular chamber 7 is completely separated from the cylindrical chamber, the flocculent material in the cylindrical chamber will still adhere to the inner wall of the built-in tube 6 and creep along the inner wall of the built-in tube 6. At this time, because the first through hole 601 is blocked, the flocculent material cannot enter the annular chamber 7. At this time, an annular guide part 602 is provided on the inner wall of the built-in tube 6. The annular guide part 602 can stop the creeping of the flocculent material when the first through hole 601 is blocked, preventing the flocculent material from creeping to the bottom of the built-in tube 6 and entering the cooling device. At the same time, when the first through hole 601 is reopened, the annular guide part 602 can also guide the flocculent material, so that the flocculent material accumulated on the annular guide part 602 can enter the annular chamber 7.

[0055] The above-mentioned design allows the lily milk to rotate when entering the cylindrical chamber, enabling the flocculent material in the lily milk to adhere to the inner wall of the built-in tube 6 and move along the inner wall of the built-in tube 6 under the flushing action, thereby entering the annular chamber 7. This avoids the flocculent material entering the cooling device and causing blockage or rapid scaling of the liquid cooling plate 2, thus extending the service life of the cooling device.

[0056] Please see Figures 2-3 , Figure 4 , Figure 6 The driving component is disposed in the cylindrical cavity, and the driving component can drive the lily milk product entering the cylindrical cavity to rotate. The driving component includes a driving device 9 fixedly installed on the hysteresis tube 5 and a rotating distributor 10 rotatably installed in the hysteresis tube 5. The output shaft of the driving device 9 is connected to the rotating distributor 10.

[0057] The rotating distributor 10 includes multiple distributor plates arranged equidistantly around the circumference, and the distributor plates are arranged along the radial direction of the hysteresis tube 5.

[0058] In use, after processing, the lily milk product is introduced into the cylindrical chamber of the stagnation tube 5. At this time, the drive device 9 drives the rotating distributor 10 to rotate at a predetermined speed, so that the lily milk product in the cylindrical chamber can make a circular motion under the drive of the distributor plate. At the same time, the lily milk product is introduced into the cooling device. The combination of the two causes the lily milk product to make a spiral motion. During this process, the flocculent material in the lily milk product can generate a greater centrifugal force due to its greater mass. Under the action of centrifugal force, the flocculent material can move towards the inner wall of the built-in tube 6 and thus adhere to the inner wall of the built-in tube 6. At the same time, the lily milk product has a downward movement, which causes the lily milk product to wash over the flocculent material, so that the flocculent material can produce a peristaltic effect on the inner wall of the built-in tube 6. When the flocculent material moves into the first through hole 601, it passes through the first through hole 601 and the second through hole 801 and enters the annular chamber 7, thereby realizing the removal of the flocculent material and preventing it from entering the cooling device with the lily milk product.

[0059] The stop assembly includes a guide plate 15 disposed on the hysteresis tube 5. The guide plate 15 is provided with a guide groove. A convex shaft 14 rotatably connected to one end of the sliding rod 12 away from the abutting wheel 13 can roll in the guide groove. The guide groove includes a vertical groove 1501 and an inclined groove 1502 disposed on the guide plate 15. When the drive mechanism is activated, it can drive the sliding rod 12 to move and cause the convex shaft 14 to move along the vertical groove 1501 and the inclined groove 1502 in sequence.

[0060] When the convex shaft 14 is at the upper end of the guide groove, the first through hole 601 coincides with the second through hole 801;

[0061] The sealing plug 19 is slidably disposed in the annular cavity 7, and a flexible rubber component 20 is provided on the sealing plug 19, with one end of the flexible rubber component 20 being lower than the other end.

[0062] In this embodiment, firstly:

[0063] When the drive mechanism is activated, it can drive the abutment wheel 13 to move through the abutment plate 17, which in turn causes the connecting rod 11 to move the sealing ring 8 downward, thereby misaligning the first through hole 601 with the second through hole 801. At this time, the annular chamber 7 and the cylindrical chamber are completely separated. Subsequently, the drive mechanism continues to drive the sealing plug 19 to move along the axial direction of the annular chamber 7, compressing the flocculent material (containing some lily milk) in the annular chamber 7. Under pressure, the flocculent material (containing some lily milk) is discharged outward through the connecting pipe. In the collection device, during this process, since the annular chamber 7 is in a closed state, the flocculent material will not return to the cylindrical chamber through the second through hole 801 and the first through hole 601 during the pressurization process. Furthermore, during the reverse movement of the sealing plug 19 to reset, the flocculent material will not enter the upper space of the sealing plug 19. This prevents the flocculent material from being squeezed and causing caking when the sealing plug 19 moves in the reverse direction, thus avoiding the flocculent material from being hidden in the upper space of the annular chamber 7 and breeding bacteria.

[0064] Secondly:

[0065] As the sealing plug 19 moves downward, it drives the flexible rubber component 20 connected to it to move downward. When it reaches the bottom wall of the annular chamber 7, because the height of one end of the flexible rubber component 20 is lower than that of the other end, the lower end of the flexible rubber component 20 can first abut against the bottom wall of the annular chamber 7. As the sealing plug 19 continues to move downward, the flexible rubber component 20 can be compressed, and at the same time, it can directionally squeeze the flocculent material in the annular chamber 7 along a predetermined trajectory. This allows more flocculent material in the annular chamber 7 to be discharged through the connecting tube, which to a certain extent also prevents the existence of dead corners where flocculent material can hide in the annular chamber 7, and further reduces the possibility of flocculent material remaining in the annular chamber 7 and causing bacteria to grow.

[0066] Please see Figure 2 , Figures 8-9 The drive mechanism connects the misaligned sealing assembly and the sealing plug 19. The drive mechanism is provided with an abutment plate 17, which cooperates with the abutment wheel 13 provided on the misaligned sealing assembly. After driving the misaligned sealing assembly to switch from the second state to the first state, it can continue to drive the sealing plug 19 to move along the annular chamber 7.

[0067] The drive mechanism includes a linear drive module 21 fixedly installed on the outer wall of the hysteresis tube 5. The linear drive module 21 is connected to the sealing plug 19 through a connecting arm 18, and the abutment plate 17 is disposed on the connecting arm 18.

[0068] The end of the abutting plate 17 facing the abutting wheel 13 is provided with a condensation groove 1703 and a vertical surface 1701, which are connected by an inclined surface 1702.

[0069] When the convex shaft 14 moves to the end of the inclined groove 1502, the abutting wheel 13 can roll on the vertical surface 1701. Furthermore, the vertical surface 1701 and the vertical groove 1501 are parallel, and the distance between them is less than the length of the sliding rod 12.

[0070] In this embodiment, when the linear drive module 21 operates, it can drive the connected arm 18 to move and cause the abutment plate 17 to move. In the initial state, the abutment wheel 13 is in the hysteresis groove 1703. Since the vertical surface 1701 and the vertical groove 1501 are parallel and the distance between them is less than the length of the sliding rod 12, when the abutment plate 17 moves downward, the sliding rod 12, the convex shaft 14, the connecting rod 11 and the sealing ring 8 can be driven to move downward through the cooperation of the abutment wheel 13 and the hysteresis groove 1703. This allows the first through hole 601 to gradually misalign with the second through hole 801. When completely misaligned, the cam shaft 14 moves to the end of the vertical groove 1501 and moves along the inclined groove 1502. At this time, the sliding rod 12 makes a lateral movement and causes the abutment wheel 13 to move along the inclined surface 1702. After the cam shaft 14 moves to the end of the inclined groove 1502, the abutment wheel 13 rolls with the vertical surface 1701, so that the height of the cam shaft 14, the connecting rod 11 and the sealing ring 8 is constant, and the annular chamber 7 and the cylindrical chamber are kept separated. After that, the linear drive module 21 continues to drive the connecting arm 18 to move downward, thereby driving the sealing plug 19 and the flexible rubber part 20 to squeeze the flocculent material, thereby discharging the flocculent material.

[0071] When the sealing plug 19 and the flexible rubber part 20 are reset, after the hysteresis groove 1703 moves to the same height as the abutment wheel 13, the restriction effect of the vertical surface 1701 on the abutment wheel 13 is released. After that, the cylindrical spring 16 releases elastic potential energy to drive the connecting rod 11 and the sealing ring 8 to move upward, and to make the convex shaft 14 move in the opposite direction along the inclined groove 1502. At the same time, the abutment wheel 13 can be embedded in the hysteresis groove 1703 until the height of the sealing plug 19 and the sealing ring 8 is reset.

[0072] With the above configuration, when the flocculent material in the annular chamber 7 is squeezed, the annular chamber 7 can be separated from the cylindrical chamber first, thereby preventing the flocculent material from returning to the cylindrical chamber during the squeezing process. Under the action of the flexible rubber component 20, the flocculent material at the bottom of the annular chamber 7 can be squeezed in a directional manner, thereby discharging more flocculent material, improving the removal rate of flocculent material, and reducing the risk of caking and bacterial growth.

[0073] As an embodiment of the present invention, the application of the heat exchange cooling device as described above in the production of lily dairy products is also proposed.
