Description

Technical Field

[0001] This invention belongs to the technical field of cooling equipment for yogurt production, and specifically relates to an energy-saving cooling device for high-protein yogurt production. Background Technology

[0002] Compared to regular yogurt, high-protein yogurt has a higher protein content and a thicker texture. In the continuous industrial production process, the temperature of the fermented yogurt material is relatively high, requiring rapid and uniform cooling to stabilize the yogurt quality, lock in nutrients, and avoid problems such as protein denaturation, decreased bacterial activity, and texture separation caused by high temperatures.

[0003] Currently, most existing yogurt production cooling devices employ a straight-tube, wrapped cooling structure. This limits the heat exchange area between the cooling medium and the yogurt material, resulting in poor cooling uniformity. Thick, high-protein yogurt tends to adhere and accumulate on the inner wall of the conveying pipe, causing localized insufficient cooling and material retention and spoilage. Furthermore, traditional cooling equipment suffers from significant pipe vibration and poor stability during operation, easily leading to equipment loosening and excessive noise. It also consumes a high amount of cooling energy, failing to meet the demands of continuous, energy-efficient, and high-quality production of high-protein yogurt. In addition, existing equipment lacks auxiliary disturbance structures, resulting in poor flowability of the yogurt material during transport, further reducing heat exchange efficiency and increasing production energy consumption and costs.

[0004] In view of the shortcomings of the existing technology, there is an urgent need to develop an energy-saving cooling device for the production of high-protein yogurt that is structurally reasonable, provides uniform cooling, is energy-efficient, operates stably, and can withstand disturbance of materials. Summary of the Invention

[0005] The purpose of this invention is to address the technical shortcomings of existing high-protein yogurt cooling equipment: thick, high-protein yogurt is prone to sudden viscosity increases, coagulation stagnation, and pipe blockage during cooling, resulting in poor material transport smoothness; limited heat exchange area and insufficient cooling uniformity lead to localized temperature differences and inconsistent product quality; the equipment suffers from high vibration damping, high energy consumption, and poor operational stability; water cooling, air cooling, and disturbance structures are prone to mutual interference, making it unsuitable for the continuous, low-energy, and high-quality industrial production requirements of high-protein yogurt. This invention provides an energy-saving cooling device for high-protein yogurt production, integrating a spiral guide propulsion structure, a fan-shaped hollow spiral vibration structure, a multi-group linked vibration disturbance structure, a full-area uniform temperature water-cooled insulation structure, and a composite vibration damping and stabilizing structure. This effectively solves problems such as viscous material stagnation and pipe blockage, uneven cooling, high energy consumption, and equipment vibration and abnormal noise during operation, significantly improving the uniformity of yogurt cooling and heat exchange efficiency, reducing production energy consumption, ensuring long-term stable operation of the equipment, and maintaining stable high-protein yogurt production quality.

[0006] To achieve the above objectives, this invention provides an energy-saving cooling device for high-protein yogurt production, comprising a conveying pipe, a cooling chamber, and a vibration chamber. The cooling chamber is sleeved and arranged at the outer end of the conveying pipe, serving as the core water-cooling structure to achieve all-around cooling of the yogurt material within the conveying pipe. The outer end of the conveying pipe has a circumferential array of spiral grooves, forming a spiral flow channel within the pipe to drive the viscous yogurt spirally forward, preventing material stagnation and congestion, while simultaneously increasing the heat exchange area of ​​the outer wall. The vibration chamber is spiral-shaped and located within the spiral grooves. The center of the vibration chamber is hollow; this hollow structure effectively reduces the chamber's weight and improves heat conduction and dissipation performance. Furthermore, the front and rear ends of the vibration chamber are respectively connected to an inlet pipe and an outlet pipe for airflow, providing the power basis for the internal vibration structure.

[0007] The cooling chamber is externally a cylindrical chamber, which is fixedly connected to the outer end face of the conveying pipe to form a sealed cooling space, effectively reducing heat loss. The interior of the cylindrical chamber houses cooling pipes, which serve as the core structure for water-cooled heat exchange, enabling low-temperature heat exchange. Fixing rings are arranged at the outer ends of the cooling pipes to position and lock them, preventing displacement or loosening. Support plates are located on both sides of the outer ends of the fixing rings, and shock absorbers are installed at the outer ends of the support plates. Through multi-stage support and shock absorption, equipment vibration is effectively offset, improving the overall operational stability of the equipment.

[0008] Furthermore, the outer end of the conveying pipe has a spiral groove that is angular, which provides good pressure resistance and excellent flow guidance. The lower part of the vibration chamber is consistent with the contour of the spiral groove, achieving precise fitting and assembly. The upper part of the vibration chamber is an arc end face, and the curvature of the outer end face of the vibration chamber is consistent with the curvature of the outer end face of the conveying pipe. The overall assembly fit is high and the structure is flat, which not only ensures efficient and uniform vibration transmission, but also ensures uniform heat exchange on the outer wall and eliminates assembly dead corners.

[0009] Furthermore, the front and rear ends of the conveying pipe are respectively equipped with an inlet pipe and an outlet pipe, which respectively realize the feeding and discharging of yogurt materials to ensure continuous production. The outer ends of the inlet pipe and the outlet pipe are respectively connected to a first flexible connecting pipe. The flexible connection structure can effectively buffer pipe vibration, adapt to slight deformation during equipment operation, and avoid the problems of loosening and abnormal noise caused by rigid connections. The outlet pipe is equipped with a flow sensor, which can monitor the material conveying flow rate in real time, allowing the staff to adjust the production parameters in real time and adapt to the continuous production rhythm of the production line.

[0010] Furthermore, the middle part of the shock absorber is a support frame 15, the inner end of which is fixedly connected to the outer end of the support plate to achieve overall rigid load-bearing and uniform and stable force distribution. A movable sleeve 16 is fitted to the outer side of the support frame 15. The movable sleeve 16 can be directly fixed, bolted, or welded to the equipment support frame 15, offering flexible assembly methods to adapt to different equipment installation conditions. Restricting bolts 17 are rotatably inserted through the upper and lower ends of the movable sleeve 16. These bolts 17 are rotatably engaged with the upper and lower ends of the support frame 15, and the array of restricting bolts 17 evenly passes through the upper and lower ends of the movable sleeve 16, achieving precise positioning and preventing structural displacement and detachment. Shock-absorbing springs 18 are arrayed between the upper and lower ends of the support frame 15 and the movable sleeve 16. These springs 18 are fitted outside the restricting bolts 17, and through the synchronous elastic deformation of multiple sets of springs 18, the vibration energy of the equipment operation is absorbed in multiple dimensions, achieving efficient vibration reduction and noise reduction, and ensuring the stability of equipment operation.

[0011] Furthermore, the cooling pipe 7 within the cooling chamber is a circular tube, and it is tightly coiled around the outer end face of the conveying pipe to maximize the heat exchange coverage area and improve heat exchange efficiency. Both ends of the cooling pipe 7 extend outside the cooling chamber, and a second connecting hose 19 is provided at both ends to facilitate the access and circulation of the cooling medium. Additionally, a cryogenic coolant circulation pump can be selectively connected externally via the second connecting hose 19 according to production needs. This cryogenic coolant circulation pump is an optional upgrade structure, and the basic cooling function of the equipment can be achieved without its participation.

[0012] Furthermore, a rubber ring 29 is provided between the fixing ring 8 and the conveying pipe, and the inner and outer rings of the rubber ring 29 are provided with through holes 30. The rubber ring 29 can fill the assembly gap between the fixing ring 8 and the conveying pipe, playing a role in anti-slip limiting and flexible buffering, reducing hard assembly wear; at the same time, the arrayed through holes 30 can effectively increase the overall damping performance of the rubber ring 29, further improve the shock absorption and covering effect of the equipment, optimize the buffering and shock absorption performance, and stabilize the structural assembly strength.

[0013] Furthermore, vibrating bodies 20 are arranged along the inner end face of the vibration chamber. The lower two sides of the vibrating bodies 20 are fixedly connected to the lower two end faces of the vibration chamber, ensuring a firm assembly, balanced force distribution, and stable vibration output. The vibrating bodies 20 contain a fan chamber 21 and a rotating chamber 22. A centrifugal fan wheel 23 rotates inside the fan chamber 21, and a flywheel 24 is coaxially fixed to the centrifugal fan wheel 23. The flywheel 24 is rotatably positioned inside the rotating chamber 22, enabling high-speed coaxial linkage operation. An air inlet 25 is located at the middle of the front end of the vibrating body 20, communicating with the front of the fan chamber 21 to receive the driving airflow. An air outlet 26 is located at the rear end of the vibrating body 20, communicating with the rear of the fan chamber 21 to discharge the heat-exchanged airflow, forming an independent airflow driving channel.

[0014] Furthermore, the air outlets 26 and air inlets 25 of adjacent vibrating bodies 20 are sealed together by a connecting hose 27, so that multiple sets of vibrating bodies 20 form a series-connected structure, and the airflow can flow step by step, so as to realize the synchronous linkage of multiple sets of vibrating bodies 20 and ensure the uniformity and continuity of vibration.

[0015] Furthermore, the front air inlet 25 of the vibrating body 20 located at the foremost end of the vibration chamber is sealed to the front air inlet pipe of the vibration chamber, and the rear air outlet 26 of the vibrating body 20 located at the rearmost end of the vibration chamber is sealed to the rear air outlet pipe of the vibration chamber. This allows for direct airflow, with the airflow circulating only within the internal channels of the vibrating body 20 and not intruding into the vibration chamber or cooling chamber. Each structure operates independently without interference. The air inlet pipe can optionally be connected to an external gas pressurization device. This gas pressurization device is an optional upgrade structure; the basic vibration and cooling functions of the equipment can be achieved without its involvement. When installed as an option, it can provide high-pressure driving airflow, further improving vibration efficiency and heat exchange effect.

[0016] Furthermore, an eccentric block 28 is fixedly provided on the outer end face of the flywheel 24. The eccentric block 28 rotates coaxially with the flywheel 24 and the centrifugal fan wheel 23 at high speed, generating a stable periodic centrifugal vibration force, which drives the vibrator 20 and the entire vibration chamber to form a uniform high-frequency micro-vibration, continuously disturbing the inner wall of the conveying pipe and the viscous yogurt material inside, effectively preventing the problem of high protein yogurt viscosity rising at low temperature, coagulation and accumulation, and pipe blockage.

[0017] Furthermore, the vibration chamber is a sealed hollow cavity, which can be selectively evacuated to form a vacuum cavity according to production conditions. This eliminates air damping within the cavity, significantly reduces vibration energy loss, improves vibration transmission efficiency, and results in significant energy savings and efficiency improvements. The interior of the cylindrical chamber, and the space between the cooling pipes and the inner wall of the chamber, is filled with high-density insulation material, which effectively isolates external heat intrusion, blocks cold leakage, stabilizes the low-temperature environment inside the cooling chamber, and reduces cooling energy consumption.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention employs a composite structure of spiral flow guide and spiral fan-shaped vibration cavity, perfectly suited to the high viscosity and easy coagulation characteristics of high-protein yogurt. The angular spiral grooves arranged in a circular array at the outer end of the conveying pipe guide the yogurt inside the pipe to form a continuous spiral propulsion flow, actively driving the uniform conveying of viscous materials, completely solving the problems of jamming, stagnation, and blockage in traditional straight pipe conveying, ensuring the continuity of material conveying; simultaneously, the spiral structure significantly expands the heat exchange area of ​​the outer wall, extends the heat exchange path, and improves basic heat exchange efficiency. The spiral fan-shaped hollow vibration cavity precisely fits the spiral grooves, ensuring strong assembly stability and uniform vibration transmission. Combined with high thermal conductivity materials, it can achieve indirect heat exchange to assist cooling, eliminating the defect of uneven local cooling.

[0019] 2. This invention employs a fully enclosed water-cooling + sealed insulation structure, resulting in uniform cooling and excellent energy efficiency. The coiled circular cooling pipes achieve 360° all-around cooling of the delivery pipes, ensuring comprehensive heat exchange without dead angles. Combined with the cylindrical sealed chamber and internal insulation material, it effectively locks in heat, preventing cold leakage and external heat interference, significantly reducing cooling energy consumption. The equipment can also be optionally equipped with a low-temperature coolant circulation pump, which can be flexibly upgraded according to production capacity and cooling precision requirements. After upgrading, it achieves closed-loop constant-temperature circulation of coolant, further improving temperature control accuracy and cooling efficiency, adapting to different production conditions.

[0020] 3. This invention employs a multi-set linked vibrating body + eccentric centrifugal vibration structure, resulting in excellent anti-coagulation and clogging effects. Multiple vibrating bodies are connected in series, driven by high-pressure airflow to rotate the centrifugal fan wheel and flywheel at high speed. This, combined with the eccentric block, generates stable high-frequency micro-vibrations. Utilizing the low-damping characteristics of the vacuum chamber, vibration loss is low and amplitude is uniform, continuously agitating viscous yogurt materials. This fundamentally prevents low-temperature coagulation and adhesion issues, continuously activating the material's flow state and enhancing heat exchange. Simultaneously, the airflow drive system, water cooling system, and vibrating chamber are completely independent, without interference, ensuring strong operational stability.

[0021] 4. This invention is equipped with a composite vibration damping, flexible buffer, and flow monitoring structure, ensuring stable equipment operation and a high degree of automation. The multi-stage composite vibration damping structure can absorb equipment vibration from all directions, resulting in excellent noise reduction and vibration damping effects. The rubber ring between the fixed ring and the conveying pipe, combined with a through-hole structure, can effectively improve damping, enhance the vibration damping coverage effect, significantly optimize the equipment's buffering and vibration damping performance, and improve the stability of the structural assembly. The soft connection structure at the inlet and outlet ends can buffer vibration and adapt to equipment deformation. The flow sensor at the outlet end can monitor the material flow in real time, enabling precise control of production parameters and adapting to continuous industrial production. The overall equipment structure is compact, highly reliable, and has a long service life. Attached Figure Description

[0025] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a welded connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances. Example 1: Combination Figures 1-5 , Figure 7This embodiment provides an energy-saving cooling device for high-protein yogurt production, including a conveying pipe 1, a cooling chamber 2, and a vibration chamber 3. The cooling chamber 2 is sleeved on the outer end of the conveying pipe 1, achieving all-round envelopment and cooling of the high-protein yogurt material inside the conveying pipe 1. The outer end of the conveying pipe 1 is provided with a circumferential array of spiral grooves 4. The spiral grooves 4 are angular grooves, which can not only significantly expand the heat exchange area of ​​the outer wall of the conveying pipe 1, but also form a stable spiral guiding channel inside the conveying pipe 1, guiding the viscous high-protein yogurt spiral to advance at a uniform speed, effectively improving the problems of jamming, stagnation, and accumulation in the conveying of viscous materials, and ensuring the continuity of material conveying.

[0026] The vibration chamber 3 is spiral-shaped and located inside the spiral groove 4. The middle part of the vibration chamber 3 is hollow, which reduces the weight of the equipment and improves the heat conduction and dissipation capacity of the chamber. The lower part of the vibration chamber 3 fits perfectly with the contour of the spiral groove 4, and the upper part of the vibration chamber 3 has a rounded end face. The curvature of the outer end face of the vibration chamber 3 is consistent with the curvature of the outer end face of the conveying pipe 1, achieving a seamless fit and uniform vibration transmission with no dead zones in heat exchange. The front and rear ends of the vibration chamber 3 are respectively connected to the air inlet pipe 5 and the air outlet pipe 6. The air inlet pipe 5 has a reserved assembly interface for the optional installation of a gas pressurization device. This structure is optional and can be used for the equipment's basic cooling and vibration functions without its participation.

[0027] A cylindrical chamber is fixedly installed on the outside of the cooling chamber 2. The cylindrical chamber is sealed and fixedly connected to the outer end face of the conveying pipe 1, forming a closed cooling space to reduce heat loss. A cooling pipe 7 is installed inside the cylindrical chamber. The cooling pipe 7 is a circular cross-section tube and is tightly coiled around the outer end face of the conveying pipe 1 to maximize the heat exchange coverage area and ensure cooling uniformity and efficiency. Both ends of the cooling pipe 7 extend outside the cooling chamber 2, and a second connecting hose 19 is connected to both ends of the cooling pipe 7. The second connecting hose 19 can be selectively connected to a cryogenic coolant circulation pump as an optional upgrade structure, which can be flexibly selected and installed according to production capacity and cooling precision requirements.

[0028] Multiple sets of fixing rings 8 are arranged at the outer end of the cooling pipe 7 to hold and position the cooling pipe 7, preventing displacement or loosening during long-term operation. A rubber ring 29 is provided between the fixing ring 8 and the conveying pipe 1, and the inner and outer rings of the rubber ring 29 are provided with through holes 30. The rubber ring 29 can fill the assembly gap, playing a role in anti-slip limiting, flexible buffering and shock absorption, and reducing hard assembly wear. The through holes 30 can effectively improve the damping effect of the rubber ring 29, enhance the overall shock absorption and covering performance, further optimize the equipment's buffering and noise reduction, vibration resistance, and ensure the stability of the structural assembly.

[0029] Support plates 9 are fixedly mounted on both sides of the outer end of the fixed ring 8. Shock absorbers 10 are mounted on the outer ends of the support plates 9, achieving stable load-bearing of the damping structure. A support frame 15 is located in the middle of the shock absorber 10. The inner end of the support frame 15 is fixedly connected to the outer end of the support plate 9, achieving rigid load-bearing. A movable sleeve 16 is mounted on the outer side of the support frame 15. The movable sleeve 16 can be directly fixed, bolted, or welded to the support frame 15, offering flexible assembly options to suit different equipment assembly requirements. Restricting bolts 17 are rotatably passed through the upper and lower ends of the movable sleeve 16. These restricting bolts 17 rotate and engage with the upper and lower ends of the support frame 15, respectively. The array of restricting bolts 17 evenly passes through the upper and lower end faces of the movable sleeve 16, achieving precise positioning and preventing structural displacement and detachment. The upper and lower ends of the support frame 15 and the movable sleeve 16 are respectively arranged with shock-absorbing springs 18. The shock-absorbing springs 18 are sleeved on the outside of the limiting bolts 17. Through the synchronous elastic deformation of multiple sets of shock-absorbing springs 18, the vibration energy generated by equipment operation and material conveying is absorbed in multiple dimensions, effectively reducing vibration and noise, and improving the stability of equipment operation.

[0030] The front and rear ends of the conveying pipe 1 are respectively equipped with an inlet pipe 11 and an outlet pipe 12. The outer ends of the inlet pipe 11 and the outlet pipe 12 are respectively connected to a first flexible connecting pipe 13. The flexible connecting structure can effectively buffer pipe vibration, isolate vibration transmission, and adapt to slight deformation during equipment operation, thereby improving the equipment assembly adaptability and stability. The outlet pipe 12 is connected to a flow sensor 14, which can monitor the flow rate of yogurt material in real time, allowing staff to adjust the conveying speed in real time according to production conditions and adapt to the continuous production line rhythm.

[0031] The working principle of this embodiment: High-protein yogurt is smoothly introduced into the conveying pipe 1 through the feed pipe 12 and the first flexible connecting pipe 14. Under the guiding action of the spiral groove 4, it forms a continuous spiral flow, autonomously propelling the conveyor and effectively preventing viscous material from stagnating and getting stuck. The cooling pipe 8 provides all-round water cooling to the conveying pipe 1 through a coiling and wrapping method. The cylindrical chamber, combined with the internal insulation structure, locks in heat and reduces cold loss, achieving energy-saving and uniform temperature cooling. During equipment operation, multiple sets of shock-absorbing springs 19 inside the shock absorber 11, along with the limiting structure, absorb equipment vibration from all directions, ensuring stable operation and no abnormal noise. The flow sensor 15 monitors the discharge flow rate in real time, ensuring continuous and stable production. The rubber ring 30 between the fixing ring 9 and the conveying pipe 1, along with the through hole 31 structure, can effectively improve damping, enhance the shock absorption and wrapping effect, flexibly buffer assembly stress, and significantly improve the overall vibration resistance and assembly stability of the equipment. The basic structure of the equipment can achieve the core functions of preventing viscous yogurt from clogging, achieving uniform temperature, and energy-saving cooling.

[0032] Example 2 Combination Figure 6Based on Example 1, this embodiment adds multiple sets of linked vibrating body disturbance structures to achieve mechanical vibration-assisted anti-condensation and airflow-assisted heat exchange efficiency, further improving cooling efficiency and material flowability. The remaining structures are completely consistent with Example 1, and will not be described again here.

[0033] In this embodiment, multiple sets of vibrating bodies 20 are uniformly arranged and fixed inside the vibration chamber 3 along the inner end face of the chamber. The lower two sides of the vibrating bodies 20 are fixedly connected to the lower two end faces of the vibration chamber 3, ensuring a firm assembly, balanced force, and stable output of vibration disturbance effect. Each set of vibrating bodies 20 is independently divided into a fan chamber 21 and a rotating chamber 22. A centrifugal fan wheel 23 is rotatably mounted inside the fan chamber 21. The centrifugal fan wheel 23 is coaxially fixedly connected to a flywheel 24. The flywheel 24 is rotatably mounted inside the rotating chamber 22, enabling high-speed coaxial linkage operation.

[0034] An air inlet 25 is provided at the middle of the front end of the vibrator 20, which is connected to the front of the fan cavity 21 for receiving the driving airflow. An air outlet 26 is provided at the rear end of the vibrator 20, which is connected to the rear of the fan cavity 21 for discharging the heat-exchanged airflow, forming an independent airflow channel for each set of vibrators 20. The air outlets 26 and air inlets 25 of two adjacent sets of vibrators 20 are sealed together by a connecting hose 27, so that multiple sets of vibrators 20 form a series-connected structure, and the airflow can be conducted step by step to realize the synchronous linkage of multiple sets of vibrators 20.

[0035] The front air inlet 25 of the vibrating body 20 located at the front end of the vibration chamber 3 is sealed to the air inlet pipe 5 at the front end of the vibration chamber 3, and the rear air outlet 26 of the vibrating body 20 located at the rear end of the vibration chamber 3 is sealed to the air outlet pipe 6 at the rear end of the vibration chamber 3. This allows airflow to be directly introduced into the interior of each series of vibrating bodies 20 through the air inlet pipe 5, and the airflow only flows within the pipes of the vibrating bodies 20, without intruding into the interior of the vibration chamber 3 or the cooling chamber 2. Each system operates independently and does not interfere with each other. With the optional gas pressurization device, high-pressure airflow can be output to drive the centrifugal fan wheel 23 to rotate at high speed, improving vibration efficiency and heat exchange effect.

[0036] An eccentric block 28 is fixedly mounted on the outer end face of the flywheel 24. The eccentric block 28 rotates coaxially with the flywheel 24 and the centrifugal fan wheel 23 at high speed, generating a stable periodic centrifugal vibration force, which drives the vibrator 20 and the overall spiral vibration chamber 3 to form uniform high-frequency micro-vibration. The continuous micro-vibration can continuously disturb the inner wall of the conveying pipe 1 and the viscous yogurt material inside, effectively breaking the problems of sudden increase in viscosity, coagulation stagnation, and pipe blockage caused by accumulation on the pipe wall during the low-temperature cooling process of high-protein yogurt. It continuously activates the fluidity of the material, greatly improves the heat exchange efficiency between the material and the pipe wall, and ensures uniform cooling.

[0037] The working principle of this embodiment is as follows: the equipment's basic cooling, vibration damping, and flow stabilization functions are consistent with those of Embodiment 1. Based on this, a gas pressurization device can be optionally installed according to production needs. High-pressure airflow is introduced into multiple sets of series-connected vibrating bodies 21 through the air inlet pipe 5, driving the centrifugal fan wheel 24 and flywheel 25 to rotate at high speed, which in turn drives the eccentric block 29 to rotate, generating high-frequency micro-vibrations. Utilizing the low-damping characteristics of the sealed, vacuum-capacitated vibration chamber 3, vibration transmission loss is low and amplitude is uniform, continuously disturbing the viscous yogurt to prevent coagulation and blockage. Simultaneously, the high-speed airflow helps to remove heat, further enhancing the heat exchange effect. The equipment can be optionally equipped with a low-temperature coolant circulation pump to achieve closed-loop constant-temperature circulation of the coolant, adapting to high-precision, high-capacity production conditions. This device achieves efficient, uniform, energy-saving, and stable cooling production of high-protein yogurt through the synergistic effects of water cooling for uniform temperature, mechanical vibration to prevent blockage, airflow-assisted heat exchange, vacuum drag reduction for increased efficiency, and flexible buffering for stable operation, adapting to the needs of continuous industrial operation.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
