[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The following is combined with Figure 1 This invention describes a sterile bacterial strain processing production line.

[0029] Understandably, referring to Figure 1 This utility model provides a sterile inoculum processing production line, including a mixing tank 100, a sterilizer 200, an inoculum addition system, and a first fermentation tank 410. The mixing tank 100 is used to contain base material, and the sterilizer 200 is used to sterilize the base material. The sterilizer 200 has a first inlet and a first outlet, and the first inlet is connected to the conveying end of the mixing tank 100. The inoculum addition system includes an inoculum addition tank 310 and an inoculum filter 320 disposed in the inoculum addition tank 310. The inoculum filter 320 is used to contain inoculum and is connected to the interior of the inoculum addition tank 310. The inoculum addition tank 310 has a second inlet and a second outlet, and the second inlet is connected to the first outlet. The inlet end of the first fermentation tank 410 is connected to the second outlet.

[0030] It should be noted that, in this embodiment of the invention, the freeze-dried bacteria are placed in the container of the filter in granular form, and the yogurt base carries the bacteria away after passing through the filter.

[0031] The aseptic culture processing production line provided by this utility model includes a culture addition system. The culture is located in the culture filter 320. The base material for making yogurt is fed into the culture addition tank 310 from the ingredient tank 100. When the base material passes through the culture filter 320, the culture is carried away. At the same time, the culture filter 320 helps to dissolve all the culture in the base material, making the culture more uniform in the yogurt base material. Furthermore, by observing the stability of the texture, acidity, viscosity, pH value, etc. of the yogurt after fermentation in the first fermentation tank 410, a foundation is provided for the production of high-quality yogurt, which is beneficial to improving yogurt quality, fermentation stability and extending shelf life.

[0032] It should be noted that in this embodiment of the present invention, the sterilizer 200 performs high-temperature sterilization on the base material, and the temperature range is usually between 63 and 95°C. The specific temperature depends on the required sterilization degree and the final use of the product.

[0033] Reference Figure 1 In this embodiment of the present invention, a first pressure monitor 810 and a first temperature controller 910 are also provided on the output route of the first discharge port of the sterilizer 200. That is, the base material is input into the sterilizer 200 from the mixing tank 100, and after passing the pressure detection of 2 to 3 bar and the temperature of 40 to 45°C, it is output to the inoculum addition tank 310 of the inoculum addition system.

[0034] It is understood that in this embodiment of the present invention, the bottom of the inoculum addition tank 310 is a conical structure, and a second discharge port is provided at the bottom of the conical structure.

[0035] The aforementioned conical structure helps push the yogurt base material inside the tank towards the second outlet. Due to the converging nature of the cone, the yogurt base material can flow out more smoothly, reducing residue at the bottom of the tank. The bottom of the tank is also easier to clean because water can flow along the conical surface to the bottom, reducing blind spots during cleaning and ensuring hygiene and safety in the production process. In addition, the conical structure helps the inoculum and base material to mix thoroughly, improving fermentation efficiency.

[0036] It should be noted that, in this embodiment of the invention, the volume of the inoculum addition tank 310 is 5 to 10 liters, and the inoculum filter 320 is a cylindrical filter screen. This can be understood as the cavity enclosed by the filter screen being the receiving part, and the filtering area of ​​the filter screen having filter holes with a diameter of 0.5 to 1.0 mm. This means that when the substrate enters the filter screen through the filter holes, it carries away the inoculum, and simultaneously, due to the effect of the filter holes, the granular inoculum disperses and dissolves into the substrate. Of course, in other embodiments, the filtering part of the inoculum filter 320 can also be configured as a strip-shaped filter hole.

[0037] Understandably, referring to Figure 1 In this embodiment of the invention, the microbial inoculation system further includes a microbial jacketed discharge pipe 330, through which the feed end and the discharge port of the first fermentation tank 410 are connected.

[0038] Specifically, the microbial culture jacketed discharge pipe 330 has a jacketed water inlet, a jacketed discharge outlet, and a jacketed water outlet. The bottom of the microbial culture addition tank 310 is also provided with a drain outlet, which is connected to the jacketed water inlet. The jacketed discharge outlet is connected to the first fermentation tank 410, and the jacketed water outlet is connected to the jacketed water outlet pipe to discharge the liquid inside the microbial culture jacketed discharge pipe 330. Of course, in some other embodiments, the microbial culture jacketed discharge pipe 330 may only have one inlet and one outlet, with the inlet used for the introduction of substrate or liquid, and the outlet used for the discharge of substrate or liquid; this is not limited here.

[0039] Understandably, referring to Figure 1In this embodiment of the invention, the aseptic inoculum treatment production line further includes a cooling water module 500, which has a cooling water outlet connected to the inoculum addition tank 310.

[0040] With the above settings, cooling water enters the inoculum addition tank 310 from the cooling water outlet of the cooling water module 500, flushing and discharging the inoculum addition tank 310. This not only allows the inoculum to dissolve quickly into the substrate, but also increases the flow rate of the substrate, achieving rapid discharge.

[0041] Understandably, referring to Figure 1 In this embodiment of the invention, the aseptic inoculum treatment production line further includes a high-temperature hot water module 600, which has a hot water outlet connected to the inoculum addition tank 310.

[0042] With the above setup, high-temperature hot water from the hot water outlet of the high-temperature hot water module 600 sterilizes and disinfects the bacterial inoculation tank 310.

[0043] It should be noted that in this embodiment of the invention, the high-temperature hot water module 600 is a hot water heater, and the cooling water module 500 is a water-cooled cooler; the specific type is not limited here. It is understood that the inoculum addition tank 310 is provided with a liquid inlet and a delivery pipe connecting to the liquid inlet. Both the cooling water outlet and the hot water outlet are connected to the delivery pipe. This arrangement reduces the complexity of the piping layout and saves space. Of course, in other embodiments, the inoculum addition tank 310 may also be provided with multiple liquid inlets, each corresponding to a cooling water outlet and a hot water outlet; this is not limited here.

[0044] It should also be noted that, referring to Figure 1 In this embodiment of the invention, a second pressure monitor 820 and a second temperature controller 920 are installed on the infusion tube. Specifically, when cooling water is input, the pressure is monitored to be 1 to 1.5 bar and the temperature is controlled to be 20 to 25°C. The cooling water is then delivered to the inoculum addition tank 310 and discharged through the inoculum jacket discharge pipe 330 to complete water flushing and discharge. When hot water is input, the pressure is monitored to be 2 to 2.5 bar and the temperature is controlled to be 90 to 125°C. The hot water is then delivered to the inoculum addition tank 310 and discharged through the inoculum jacket discharge pipe 330, thereby completing the sterilization and disinfection of the inoculum addition tank 310 and filters of the inoculum addition system.

[0045] Understandably, referring to Figure 1 In this embodiment of the invention, the microbial culture addition system further includes a spray cleaning structure 340, which is disposed on the microbial culture addition tank 310 and is used to spray and clean the inside of the microbial culture addition tank 310.

[0046] The cleaning solution is delivered to the spray cleaning structure 340 through the cleaning pipe. The spray cleaning structure 340 thoroughly cleans the inoculum addition tank 310 and other components of the inoculum addition system, such as the filter. The cleaning effect is significant, improving cleaning efficiency and quality, and also helps to maintain the hygiene and safety of the production environment.

[0047] Specifically, in this embodiment of the utility model, the spray cleaning structure 340 is a spray ball, which can be fixed or rotating, and is not limited here.

[0048] It should be noted that, referring to Figure 1 In this embodiment of the utility model, a third pressure monitor 830 and a third temperature controller 930 are provided on the cleaning pipe. The cleaning liquid is allowed to enter the spray ball through a pressure of 1 to 1.5 bar and a temperature of 70 to 80°C to thoroughly clean the inoculum addition tank 310. Finally, the liquid is discharged through the inoculum jacket discharge pipe 330.

[0049] Understandably, referring to Figure 1 In this embodiment of the invention, the aseptic strain processing production line further includes a first feed valve 710 for introducing and controlling the conveying of base material. The input end of the first feed valve 710 is connected to the first discharge port, and the output end of the first feed valve 710 is connected to the second feed port.

[0050] With the above configuration, the first feed valve 710 introduces the substrate into the inoculum addition tank 310 through the second feed port, where it mixes with the inoculum. By controlling the first feed valve 710, the substrate can enter the inoculum addition tank 310 at an appropriate flow rate and volume, which helps to ensure uniform mixing between the substrate and the inoculum. This is crucial for the subsequent bio-fermentation process, as uniform mixing provides a good growth environment and ensures even distribution of the inoculum.

[0051] It should be noted that the operation of the first feed valve 710 can be automatic or manual, depending on the specific process flow, control system and operation requirements.

[0052] Understandably, referring to Figure 1 In this embodiment of the invention, the aseptic strain processing production line further includes a second feed valve 720 for introducing and controlling the delivery of aseptic air, and the output end of the second feed valve 720 is connected to the strain addition tank 310.

[0053] With the above setup, sterile air is introduced into the inoculum addition tank 310 through the second inlet valve 720. Its main function is to cool and drain the tank. This can be understood as follows: after the inoculum addition tank 310 undergoes thorough sterilization by the high-temperature hot water module 600, the internal temperature is high and the internal pressure has increased. Therefore, introducing sterile air helps to reduce the pressure inside the tank, thus facilitating the drainage of accumulated water. This operation not only ensures cooling of the tank environment but also helps maintain pressure balance, creating suitable conditions for subsequent operations.

[0054] It should be noted that the second feed valve 720 can be operated automatically or manually, depending on the specific process flow, control system and operational requirements.

[0055] Understandably, referring to Figure 1 In this embodiment of the invention, the sterile inoculum treatment production line further includes a third feed valve 730 for introducing and controlling the delivery of sterile water, and the output end of the third feed valve 730 is connected to the inoculum addition tank 310.

[0056] With the above structure, the inoculum addition tank 310 is further cooled by sterile water. The injection of sterile water can quickly absorb the heat inside the tank, reduce the temperature inside the tank, and improve the cooling efficiency.

[0057] It should be noted that the third feed valve 730 can be operated automatically or manually, depending on the specific process flow, control system, and operational requirements. It should also be noted that the first, second, and third feed valves mentioned above can be regulating valves, ball valves, etc.

[0058] It is understood that in this embodiment of the invention, the culture jacket outlet pipe 330 is not only used for discharging the culture, but also for receiving the cleaning solution, the cooling water output from the cooling water module 500, and the sterile water injected through the third inlet valve 730. This facilitates cleaning and cooling, ensuring a stable output of yogurt base mixed with the culture and providing suitable temperature conditions. It should be noted that in this embodiment, the jacket outlet pipe is equipped with a fourth pressure monitor 840 and a fourth temperature controller 940 to improve the reliability and safety of water delivery.

[0059] It should be noted that, referring to Figure 1 In this embodiment of the invention, the aseptic strain processing production line further includes a second fermenter 420, the feed end of which is connected to the first discharge port.

[0060] With the above arrangement, after the discharge operation of the inoculum jacket discharge pipe 330 is completed, the inoculum addition tank 310 undergoes thorough cleaning, sterilization, and cooling. During this process, the inoculum addition system suspends feeding and inoculum input. To make full use of this downtime and improve production efficiency, the base material in the ingredient tank 100 is smoothly transferred to the second fermentation tank 420 after strict pressure testing and precise temperature control. This process design not only ensures the continuous operation of the production line but also allows for flexible switching to adapt to the production of different batches of dairy products to meet diverse needs, thereby optimizing the allocation and use of production resources.

[0061] Specifically, refer to Figure 1 In this embodiment of the invention, the aseptic strain processing production line further includes a discharge switching valve 740, which is provided with a first material inlet, a second material inlet, and a material outlet. The discharge switching valve 740 has a first working state and a second working state.

[0062] In the first working state, the first feeding inlet is connected to the second discharge outlet through the inoculum jacket discharge pipe 330, and the feeding outlet is connected to the feeding end of the first fermentation tank 410; in the second working state, the second feeding inlet is connected to the first discharge outlet, and the feeding outlet is connected to the feeding end of the second fermentation tank 420.

[0063] With the above arrangement, the first feeding inlet is connected to the second discharge outlet, so that the substrate mixed with microorganisms can flow from the microorganism addition tank 310 through the microorganism jacket discharge pipe 330 and the discharge conversion valve 740 to the feeding outlet. The feeding outlet is connected to the feeding end of the first fermentation tank 410, so that the substrate mixed with microorganisms can be directly transported to the first fermentation tank 410 for fermentation.

[0064] The second material inlet is connected to the first material outlet, allowing the base material to directly enter the discharge switching valve 740, while the material outlet is connected to the feed end of the second fermentation tank 420, so that the base material can be transported to the second fermentation tank 420 for fermentation.

[0065] The discharge switching valve 740 can easily switch the material flow direction according to production needs, improving the operational flexibility and adaptability of the production line. By switching the discharge switching valve 740, materials can be quickly transported to different fermentation tanks, reducing downtime, improving production efficiency, and enabling more efficient use of resources to process multiple batches or different types of dairy products simultaneously.

[0066] It should be noted that, in this embodiment, the above-mentioned discharge switching valve 740 is a two-position three-way valve; in addition, the output path of the discharge switching valve 740 is equipped with a fifth pressure monitor 850 and a fifth temperature controller 950, and the base material is transported to the corresponding fermentation tank after strict pressure detection and precise temperature control.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
