Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, specifically a cheese constant temperature fermentation equipment and process with aseptic sampling function. Background Technology

[0002] With the continuous upgrading of the dairy industry and the increasing demand from consumers for high-quality cheese, cheese fermentation processes and equipment are gradually evolving from traditional manual operations to fully automated, standardized, and clean processes. Modern fermentation equipment increasingly emphasizes mechanical innovation in key areas such as raw material pretreatment, process monitoring, aseptic operation, and efficient separation, driving technological iterations towards intelligent, refined, and food safety assurance. Currently, intelligent fermentation equipment integrating multi-stage filtration, precise temperature control, automatic stirring, and aseptic sampling has become an important direction for improving the quality and efficiency of cheese production lines and promoting large-scale development, playing a significant role in enhancing product quality consistency, hygiene and safety, and production efficiency.

[0003] Existing cheese fermentation equipment mostly uses a stirring motor to drive a single stirring shaft to achieve material mixing. In the sampling and separation stages, most equipment adopts manual sampling or a simple mechanical valve structure, and the separation methods are mainly gravity sedimentation, static filtration or conventional pressure filtration.

[0004] In existing technologies, firstly, raw material filtration and separation devices are mostly single-stage or static structures, making it difficult to achieve efficient and graded filtration of impurities of different particle sizes. This easily leads to filter clogging and impurity residue. Secondly, the stirring components are usually single rotating structures with limited stirring coverage. Dead corners exist within the fermentation tank, easily causing material stratification, local sedimentation, and uneven fermentation. Furthermore, the integration of the cooling and lubrication system with the power system is low, easily resulting in localized heating and high frictional losses. Finally, there is a lack of sampling and cleaning processes and a lack of dedicated aseptic mechanisms. The sampling process is prone to cross-contamination, and the separation process is inefficient with high solid-liquid residue. Therefore, those skilled in the art provide a cheese constant-temperature fermentation device and process with aseptic sampling capabilities to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a cheese constant temperature fermentation device and process with aseptic sampling function to solve the problems raised in the prior art.

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

[0007] The fermentation equipment includes a pretreatment unit, a fermentation unit, a sampling unit, a separation unit, and a temperature control unit. The pretreatment unit and the fermentation unit are connected, the sampling unit and the separation unit are tightly connected, the separation unit and the fermentation unit are connected, and the temperature control unit and the fermentation unit are tightly connected.

[0008] By adopting the above technical solution, the pretreatment unit first performs multi-stage processing on the raw materials, the fermentation unit carries out the entire fermentation process, the sampling unit performs aseptic sampling of the fermentation materials, the separation unit completes the solid-liquid separation of the fermentation products, and the temperature control unit provides dynamic temperature regulation for the entire fermentation process. In terms of workflow, the raw materials are initially purified by the various components of the pretreatment unit and then transported to the fermentation unit. During fermentation, the sampling unit periodically samples and analyzes the fermentation broth to ensure controllable fermentation conditions. After fermentation, the separation unit performs efficient solid-liquid separation of the fermentation products, and the temperature control unit precisely regulates the ambient temperature of the fermentation tank through heating and cooling components installed within the structure. All parts are connected by interconnected or fastened connections to ensure smooth fluid flow and stable operation of the mechanism. Through the collaboration of these multiple mechanisms and the efficient linkage of components, the entire process of cheese fermentation, from raw material pretreatment, fermentation control, process sampling to product separation, can be automated, ensuring controllable fermentation conditions, stable product quality, and a safe and hygienic production process, thereby improving the efficiency of cheese fermentation.

[0009] Furthermore, the pretreatment mechanism includes a filter assembly, a pasteurizer, and a plate heat exchanger. The filter assembly is connected to the pasteurizer, the pasteurizer is connected to the plate heat exchanger, and the plate heat exchanger is connected to the fermentation mechanism. The pasteurizer is used to kill harmful microorganisms in the raw milk, and the plate heat exchanger is used to cool the raw milk to a suitable fermentation temperature after pasteurization.

[0010] By adopting the above technical solution, raw milk first enters the filtration assembly, undergoing multi-stage filtration to effectively remove suspended impurities and large particles, improving the purity of subsequent sterilization and fermentation. The filtered raw milk then flows into a pasteurizer, where it is heated to a set temperature and maintained for a certain time to thoroughly kill harmful microorganisms, ensuring food safety. The sterilized, high-temperature milk then enters a plate heat exchanger, where its efficient heat exchange structure rapidly lowers the milk temperature to the suitable temperature required for fermentation, preventing damage to the activity of fermenting bacteria from high temperatures. The entire workflow is continuous and interconnected, enabling rapid and precise temperature control of the milk while ensuring thorough purification and efficient sterilization of the raw materials. This structure and process make the pretreatment process automatic, efficient, and hygienic, providing a clean, safe, and temperature-appropriate milk source for subsequent fermentation stages, thereby improving the quality and process stability of cheese products.

[0011] Furthermore, the filtration assembly includes a first filter screen, a second filter screen, a filter hole motor, and a hydrocyclone separator.

[0012] By adopting the above technical solution, raw milk first enters the separation chamber through the inlet of the hydrocyclone separator. Under the action of high-speed rotation, the raw milk achieves preliminary impurity sedimentation and liquid-solid separation, improving the efficiency of subsequent filtration. After the initial separation, the raw milk flows through the first and second filter screens. The first filter screen is responsible for intercepting large particles of impurities, while the second filter screen is driven by a filter hole motor to rotate. The rotation speed and filter hole alignment can be dynamically adjusted according to filtration needs, effectively preventing filter screen clogging and improving filtration accuracy. The two filter screens abut against each other to ensure a tight fit at the filtration interface, preventing impurities from leaking through. The filtered milk is discharged through the filtrate outlet. Impurities are intercepted and cleaned periodically, making the entire filtration process efficient and continuous. Using the above structure, multi-stage efficient filtration of impurities of different particle sizes in raw milk can be achieved, ensuring the purity of raw materials in subsequent sterilization and fermentation stages, and significantly improving the hygiene, safety, and quality consistency of cheese fermentation products.

The helical rod is located in the connecting pipe to enhance the cooling effect. Lubricating oil circulates through the pump chamber and gear chamber, achieving comprehensive lubrication and cooling of the transmission components, effectively preventing heat generation and wear caused by high-speed operation. This structure achieves efficient and reliable power transmission and multi-angle uniformity of stirring. Simultaneously, the cooling and lubrication assembly cools and lubricates key components throughout the entire process, extending equipment life, improving stirring and fermentation efficiency, and ensuring stable temperature and power during the fermentation process, creating favorable conditions for high-quality cheese fermentation.

[0016] By adopting the above technical solution, the stirring assembly includes a stirring frame, a telescopic stirring rod, a stretching block, a sliding column, a first electromagnetic block, a first magnetic block, a second electromagnetic block, a second magnetic block, a sliding rack, a first elastic element, a second elastic element, a third elastic element, a sleeved stirring rod, and an angle gear. The fermentation tank is shaped like a figure eight, and the stirring assembly is provided in two sets, with the two sets of stirring assemblies at a 90-degree angle. Specifically, the bevel gear set is driven by the stirring frame to achieve power input; the stirring frame is slidably connected to the stretching block, allowing the stretching block to slide along the stirring frame, thereby driving the telescopic stirring rod to extend and retract axially; the telescopic stirring rod is rotatably connected to the stretching block, enabling the stirring end to extend, retract, and rotate under drive.

The two sets of stirring components are arranged at 90 degrees to fully cover the entire space of the figure-eight fermentation tank, which greatly improves the uniformity of stirring and fermentation efficiency, effectively prevents material deposition or clumping, and ensures the continuity of the cheese fermentation process and product quality.

[0017] Furthermore, the sampling mechanism includes a micro-pump, a sampling needle, a rotating block, an eddy current motor, a UV disinfection lamp assembly, a disinfection inlet pipe, an outlet pipe, a control valve, and a transparent quartz tube. The micro-pump and the transparent quartz tube are connected, the transparent quartz tube and the sampling needle are connected, the disinfection inlet pipe and the transparent quartz tube are connected, the disinfection inlet pipe and the outlet pipe are both securely connected to the transparent quartz tube and the control valve, the rotating block and the transparent quartz tube are rotatably connected, the eddy current motor and the transparent quartz tube are securely connected, the eddy current motor and the rotating block are drive-connected, the UV disinfection lamp assembly and the transparent quartz tube are securely connected, the disinfection inlet pipe is used for the entry of disinfectant, and the outlet pipe is used for the discharge of sampled liquid.

[0018] By adopting the above technical solution, the disinfection inlet tube injects disinfectant into the translucent quartz tube through a control valve. Combined with the efficient irradiation of the UV disinfection lamp group, the sampling needle and sampling channel are sterilized comprehensively. During sampling, an eddy current motor drives a rotating block, causing the translucent quartz tube and sampling needle to rotate rapidly, improving disinfection coverage and uniform liquid distribution. Subsequently, a micro-suction pump is activated, drawing the fermentation broth sample into the translucent quartz tube through the sampling needle, ensuring accurate sampling and aseptic operation. After sampling, the sampling channel and sampling needle are emptied of residual liquid through the discharge tube to prevent cross-contamination, and the UV disinfection lamp group is activated again for secondary disinfection. This structure, through the organic combination of mechanical drive, physical ultraviolet sterilization, and chemical liquid disinfection, achieves efficient, automatic, and aseptic control of the entire sampling process. It not only ensures the purity of the sampled material but also significantly improves the hygiene and safety level of the equipment and the efficiency of automated operation.

[0019] Furthermore, the separation mechanism includes a separation box, a hydraulic cylinder, a vibrating pusher plate, a filter plate, and a pulverizer. The hydraulic cylinder is fastened to the separation box, and the hydraulic cylinder is driven to the vibrating pusher plate. The vibrating pusher plate is inclined. The separation box is connected to the fermentation tank. The micro-suction pump and the light-transmitting quartz tube are both fastened to the separation box. The vibrating pusher plate abuts against the filter plate. The filter plate is fastened to the separation box. The separation box is connected to the pulverizer.

[0020] By adopting the above technical solution, after fermentation, the material in the fermentation tank enters the separation box through a connecting pipe, which drives the hydraulic cylinder to start, causing the vibrating pusher to reciprocate towards the filter plate at a certain frequency and force. The vibrating pusher is inclined, forming a large contact area with the filter plate, effectively promoting the uniform distribution of material on the filter plate surface, while generating vibration force to improve separation efficiency. The filter plate has a porous structure and is firmly connected to the separation box, which can efficiently intercept solid cheese particles, allowing liquid whey to pass smoothly through the filter holes and be discharged. The push and vibration actions work together to prevent solids from clogging the filter holes, improving the continuity and stability of the separation process. The separated solid cheese is connected to a crusher at the bottom of the separation box, where the crusher crushes and homogenizes the cheese blocks, facilitating subsequent processing or packaging. The tight connection between the separation box and the micro-suction pump and the light-transmitting quartz tube facilitates sampling and online monitoring. With the above structure, the separation mechanism can achieve automated, efficient, and low-residue separation of cheese and whey, significantly improving the yield and hygiene safety level of the finished product, and providing strong support for the standardization and quality control of subsequent cheese products.

[0021] Furthermore, the temperature control mechanism includes a heating box, a circulating pump, and a circulating pipe. The heating box and the circulating pump are connected, the circulating pump and the circulating pipe are connected, the circulating pipe and the cooling box are connected, the circulating pipe surrounds the outside of the fermenter, and the circulating pump and the reflux pipe are connected.

[0022] By adopting the above technical solution, during the fermentation process, heating elements are installed in the heating chamber to heat the heat medium. A circulating pump continuously delivers the heated medium through a circulation pipe to a circulation loop covering the outside of the fermentation tank, achieving uniform heating of the entire fermentation tank or specific areas. When the fermentation tank temperature exceeds the set range, the control system can switch the circulation path, connecting the circulation pipe to the cooling chamber to introduce cooling medium, quickly removing excess heat from the tank and achieving efficient cooling. The return pipe is used to recover the cooling medium back to the cooling chamber, forming a closed-loop flow, improving system energy efficiency and preventing external contamination. Through this structure, the coordinated action of each component achieves real-time and precise temperature control of the fermentation tank, enabling both rapid heating and efficient cooling, ensuring the fermentation environment remains within the ideal temperature range set by the process, greatly improving fermentation efficiency and cheese quality stability, and effectively reducing energy consumption and the need for manual intervention.

[0023] The specific process is as follows:

[0024] A. The filtration components filter the raw milk sequentially to remove impurities and large particles; the filtered raw milk enters the pasteurizer, is heated to 65-75℃ and kept at a constant temperature for 15-30 minutes to kill harmful microorganisms; the pasteurized raw milk immediately enters the plate heat exchanger to cool down to 32-40℃, creating a suitable temperature environment for fermentation.

[0025] B. The cooled raw milk is transported to the fermentation tank, and fermentation bacteria are added according to the set ratio. The stirring components are started to achieve uniform mixing. During the fermentation process, the temperature control mechanism adjusts the temperature inside the fermentation tank in real time within the range of 32-40℃. The stirring components run periodically to prevent sedimentation and temperature stratification.

[0026] C. During the fermentation process, the sampling unit automatically extracts fermentation samples through the coordinated action of micro-pumps, sampling needles, and UV disinfection lamps, either periodically or according to testing needs. It also detects pH value, microbial indicators, and fermentation completion rate online or offline. The entire sampling process is sterile through UV disinfection and liquid cleaning. After each cycle of the process, the equipment automatically cleans and disinfects itself through the coordinated action of circulation pipes, disinfection inlet pipes, and outlet pipes, providing hygiene assurance for the next fermentation batch.

[0027] D. After fermentation is complete, the material is separated into solid and liquid components by the combined action of the hydraulic cylinder, vibrating pusher, and filter plate in the separation mechanism. The cheese is pre-treated and shaped by the crusher, and the whey and residue are discharged and collected through pipelines respectively.

[0028] E. Before feeding and adding bacteria to the fermenter, the heating box and circulation pump in the temperature control mechanism are started first. The heating medium is preheated to the set temperature (32-40℃) through the circulation pipe and circulates through the circulation pipe around the fermenter to make the temperature of the inner wall of the fermenter reach the target range, so that the temperature of the fermentation liquid can be quickly balanced with the temperature of the equipment wall after injection.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] By using a first and second filter screen in contact with each other and cooperating with the dynamic rotation of the filter hole motor, combined with the high-speed swirling sedimentation of the hydrocyclone separator, gradient and efficient separation of impurities of various particle sizes in the raw milk can be achieved. This ensures smooth fluid flow and efficient heat exchange during subsequent pasteurization and rapid cooling by the plate heat exchanger. The heating box, circulating pump, circulating pipe, cooling box, and reflux pipe are precisely arranged around the fermentation tank, allowing the heat and cooling media to act efficiently and evenly on all areas of the tank. This enables rapid temperature response and dynamic adjustment of zones, providing a constant, suitable, and highly uniform growth environment for the fermentation strains.

[0031] The transmission assembly employs a multi-stage power transmission structure including a stirring motor, worm gear, transmission gear, screw, bevel gear set, and pump gear set. Combined with a lubrication box, cooling box, and internally designed pump chamber, gear chamber, rolling chamber, bearings, and ball bearings, it ensures efficient and uniform stirring action and adjustable torque. Furthermore, the end-to-end lubrication and cooling effectively reduces operating friction and wear. Two sets of stirring components are arranged in a 90-degree staggered configuration. Through the linkage of telescopic stirring rods, tension blocks, sliding racks, and multiple sets of electromagnetic and magnetic blocks and elastic elements, the stirring head achieves multi-dimensional automatic extension and retraction, angle adjustment, and adaptive distribution, significantly improving stirring coverage and microenvironment consistency within the complex space of the figure-eight shaped tank.

[0032] The sampling mechanism combines components such as a micro-pump, rotating block, eddy current motor, UV disinfection lamp assembly, disinfection inlet pipe, outlet pipe, and transparent quartz tube to achieve mechanical rotation of the sampling channel and sampling needle, and simultaneous multi-stage physical and chemical disinfection. Each sampling is treated with both ultraviolet light and disinfectant to effectively prevent cross-contamination. The separation mechanism integrates a hydraulic cylinder, tilting vibrating pusher, filter plate, and crusher to ensure continuous solid-liquid separation of cheese, low residue, and uniform particle size in the finished product.

[0045] Please see Figure 1 - Figure 10 As shown, this invention provides a cheese constant-temperature fermentation device and process technology solution with aseptic sampling function:

[0046] The fermentation equipment includes a pretreatment unit 1, a fermentation unit 2, a sampling unit 3, a separation unit 4, and a temperature control unit 5. The pretreatment unit 1 and the fermentation unit 2 are connected, the sampling unit 3 and the separation unit 4 are tightly connected, the separation unit 4 and the fermentation unit 2 are connected, and the temperature control unit 5 is tightly connected to the fermentation unit 2.

[0047] By adopting the above technical solution, the pretreatment unit 1 first performs multi-stage treatment on the raw materials, the fermentation unit 2 carries out the entire fermentation process, the sampling unit 3 achieves aseptic sampling of the fermentation materials, the separation unit 4 completes the solid-liquid separation of the fermentation products, and the temperature control unit 5 provides dynamic temperature regulation for the entire fermentation process. In terms of workflow, the raw materials are initially purified by the various components of the pretreatment unit 1 and then transported to the fermentation unit 2. During fermentation, the sampling unit 3 periodically samples and analyzes the fermentation liquid to ensure controllable fermentation conditions. After fermentation, the separation unit 4 performs efficient solid-liquid separation of the fermentation products, and the temperature control unit 5 uses heating and cooling elements within its structure to precisely regulate the ambient temperature of the fermentation tank 24. All parts are connected by interconnection or fastening to ensure smooth fluid flow and stable operation of the mechanism. Through the collaboration of these multiple mechanisms and the efficient linkage of components, the entire process of cheese fermentation, from raw material pretreatment, fermentation control, process sampling to product separation, can be automated, ensuring controllable fermentation conditions, stable product quality, and a safe and hygienic production process, thereby improving the efficiency of cheese fermentation.

[0048] Furthermore, the pretreatment unit 1 includes a filter assembly 11, a pasteurizer 12, and a plate heat exchanger 13. The filter assembly 11 and the pasteurizer 12 are connected, the pasteurizer 12 and the plate heat exchanger 13 are connected, and the plate heat exchanger 13 is connected to the fermentation unit 2. The pasteurizer 12 is used to kill harmful microorganisms in the raw milk, and the plate heat exchanger 13 is used to cool the raw milk to a suitable fermentation temperature after sterilization.

[0049] By adopting the above technical solution, the raw milk first enters the filtration component 11, where it undergoes multi-stage filtration to effectively remove suspended impurities and large particles, improving the purity of subsequent sterilization and fermentation. The filtered raw milk then flows into the pasteurizer 12, where it is heated to a set temperature and maintained for a certain time to thoroughly kill harmful microorganisms, ensuring food safety. The sterilized, high-temperature milk then enters the plate heat exchanger 13, where a highly efficient heat exchange structure rapidly lowers the milk temperature to the suitable temperature required for fermentation, preventing damage to the activity of fermenting bacteria from high temperatures. The entire workflow is continuous, ensuring thorough purification and efficient sterilization of the raw materials while achieving rapid and precise temperature control of the milk. This structure and process make the pretreatment process automatic, efficient, and hygienic, providing a clean, safe, and temperature-appropriate milk source foundation for subsequent fermentation, thereby improving the quality and process stability of the cheese product.

[0050] Furthermore, the filter assembly 11 includes a first filter screen 111, a second filter screen 112, a filter hole motor 113, and a hydrocyclone separator 114.

[0051] By adopting the above technical solution, raw milk first enters the separation chamber through the inlet 1141 of the hydrocyclone separator 114. Under the action of high-speed rotation, the raw milk achieves preliminary impurity sedimentation and liquid-solid separation, improving the efficiency of subsequent filtration. After the initial separation, the raw milk flows through the first filter screen 111 and the second filter screen 112. The first filter screen 111 is responsible for intercepting large particles of impurities, while the second filter screen 112 is driven to rotate by the filter hole motor 113. The rotation speed and filter hole alignment can be dynamically adjusted according to filtration requirements, effectively preventing filter screen blockage and improving filtration accuracy.

[0058] Furthermore, the separation mechanism 4 includes a separation box 41, a hydraulic cylinder 42, a vibrating push plate 43, a filter plate 44, and a pulverizer 45.

[0059] By adopting the above technical solution, after fermentation, the material in the fermentation tank 24 enters the separation box 41 through the connecting pipe 225, which drives the hydraulic cylinder 42 to start, driving the vibrating pusher 43 to reciprocate towards the filter plate 44 at a certain frequency and force.

The filter plate 44 has a porous structure and is firmly connected to the separation box 41, which can efficiently intercept solid cheese particles and allow liquid whey to pass smoothly through the filter holes and be discharged. The push and vibration actions work together to prevent solids from clogging the filter holes and improve the continuity and stability of the separation process. The separated solid cheese is connected to the crusher 45 through the lower part of the separation box 41, where the crusher 45 crushes and homogenizes the cheese blocks, facilitating subsequent processing or packaging. The tight connection between the separation box 41 and the micro-suction pump 31 and the light-transmitting quartz tube 310 facilitates sampling and online monitoring.

[0061] By adopting the above technical solution, during the fermentation process, the heating chamber 51 is equipped with heating elements to heat the heat medium. The circulating pump 52 continuously transports the heated heat medium through the circulating pipe 53 to the circulation loop covering the outside of the fermentation tank 24, achieving uniform heating of the entire fermentation tank 24 or its sections. When the temperature of the fermentation tank 24 exceeds the set range, the control system can switch the circulation path, connecting the circulating pipe 53 to the cooling chamber 224, introducing cooling medium to quickly remove excess heat from the tank, achieving efficient cooling. The return pipe 223 is used to recover the cooling medium to the cooling chamber 224, forming a closed-loop flow, improving system energy efficiency and preventing external contamination. Through the above structure, the coordinated action of each component achieves real-time and precise temperature control of the fermentation tank 24, enabling both rapid heating and efficient cooling, ensuring that the fermentation environment is always within the ideal temperature range set by the process, greatly improving fermentation efficiency and cheese quality stability, and effectively reducing energy consumption and the need for manual intervention.

[0062] The specific process is as follows:

[0063] A. The filter assembly 11 filters the raw milk sequentially to remove impurities and large particles; the filtered raw milk enters the pasteurizer 12, is heated to 65-75℃ and kept at a constant temperature for 15-30 minutes to kill harmful microorganisms; the pasteurized raw milk immediately enters the plate heat exchanger 13 to cool down to 32-40℃ to create a suitable temperature environment for fermentation.

[0064] B. The cooled raw milk is transported to the fermentation tank 24, and fermentation bacteria are added according to the set ratio. The stirring component 23 is started to achieve uniform mixing. During the fermentation process, the temperature control mechanism 5 adjusts the temperature inside the fermentation tank 24 in real time within the range of 32-40℃. The stirring component 23 runs periodically to prevent sedimentation and temperature stratification.

[0065] C. During the fermentation process, the sampling unit 3 automatically extracts fermentation samples through the coordinated action of the micro-pump 31, sampling needle 32, and UV disinfection lamp group 36, either at regular intervals or according to testing requirements. It also detects pH value, microbial indicators, and fermentation completion rate online or offline. The entire sampling process is sterile by using UV disinfection and liquid cleaning. After each cycle of the process, the equipment automatically cleans and disinfects itself through the coordinated action of the circulation pipe 53, disinfection inlet pipe 37, and outlet pipe 38, providing hygiene assurance for the next fermentation batch.

[0066] D. After fermentation is complete, the material is separated into solid and liquid components by the combined action of the hydraulic cylinder, vibrating push plate 43 and filter plate 44 in the separation mechanism 4. The cheese is pre-treated and shaped by the crusher 45, and the whey and residue are discharged and collected through pipelines respectively.

[0067] E. Before feeding and adding bacteria to fermenter 24, the heating box 51 and circulation pump 52 in temperature control mechanism 5 are started first. The heating medium is preheated to the set temperature (32-40℃) through circulation pipe 53 and circulated through the circulation pipe 53 around fermenter 24 so that the temperature of the inner wall of fermenter 24 reaches the target range, ensuring that the temperature of the fermentation liquid can be quickly balanced with the temperature of the equipment wall after injection.

[0068] The working principle of this invention is as follows: by setting the first filter screen 111 and the second filter screen 112 in contact and cooperating with the dynamic rotation of the filter hole motor 113, combined with the high-speed swirling sedimentation of the hydrocyclone separator 114, it is possible to achieve gradient and efficient separation of impurities of various particle sizes in the raw milk, ensuring smooth fluid flow and heat exchange efficiency during the subsequent pasteurization process of the pasteurizer 12 and the rapid cooling process of the plate heat exchanger 13. The heating box 51, circulating pump 52, circulating pipe 53, cooling box 224, and return pipe 223 are precisely arranged around the fermentation tank 24, enabling the heat and cooling media to act efficiently and evenly on all areas of the tank, achieving rapid temperature response and dynamic adjustment of zones, and providing a constant, suitable, and highly uniform growth environment for the fermentation strains. The transmission component 21 adopts a multi-stage power transmission structure including a stirring motor 211, worm gear 213, transmission gear 214, screw 215, bevel gear set 216, and pump gear set 217. Combined with the lubrication box 221, cooling box 224, and the internally set pump chamber 2211, gear chamber 2212, rolling chamber 2213, bearing 219, and ball bearing 218, it not only ensures efficient and uniform stirring action and adjustable torque, but also effectively reduces operating friction and wear through full-process lubrication and cooling. Two sets of stirring components are arranged in a staggered 2390-degree configuration. Through the linkage of telescopic stirring rods 232, stretching blocks 233, sliding racks 239, and multiple sets of electromagnetic and magnetic blocks and elastic elements, the stirring heads achieve multi-dimensional automatic extension and retraction, angle adjustment, and adaptive distribution, significantly improving stirring coverage and microenvironment consistency within the complex space of the figure-eight shaped tank. The sampling mechanism 3 uses a combination of components such as a micro-pump 31, rotating block 33, eddy current motor 35, UV disinfection lamp group 36, disinfection inlet pipe 37, outlet pipe 38, and transparent quartz tube 310 to achieve mechanical rotation of the sampling channel and sampling needle 32, and simultaneous multi-stage physical and chemical disinfection. Each sampling can be treated with both ultraviolet light and disinfectant, effectively preventing cross-contamination. The separation mechanism 4, through the integration of a hydraulic cylinder 42, tilting vibrating pusher 43, filter plate 44, and crusher 45, ensures continuous solid-liquid separation of the cheese, low residue, and uniform particle size in the finished product.
