[0028] Currently, "Zhen Guoli" products have pioneered the domestic market for room-temperature dairy beverages containing granules, and have even expanded into the yogurt category. However, due to the rapid development of emerging beverages, higher demands are being placed on the taste and form of traditional dairy products containing granules, requiring enrichment and improvement of the granule texture and variety in existing products. Specifically, in the production process of yogurt containing granules, aseptic processing of the jam is a crucial step in ensuring granule sterility and meeting product quality requirements. Therefore, how to improve production efficiency, ensure uniform mixing of yogurt containing granules, and maintain aseptic and controllable processing to improve the granule texture and increase production speed are problems that researchers in this field need to solve.

[0029] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figure 1 As shown, this embodiment provides a sterile jam and granule addition system, including a jam conveying device, a yogurt conveying device, a mixing device, a pressure device, a cleaning device, and a sterilization device. The jam conveying device is used to convey jam and granules, and the yogurt conveying device is used to convey yogurt. The jam, granules, and yogurt are mixed evenly at the mixing device and then conveyed to the filling machine 100. The pressure device is used to accelerate the discharge of the jam conveying device, the cleaning device is used to clean the discharge port of the jam conveying device, and the sterilization device is used to sterilize the discharge port of the jam conveying device.

[0031] Specifically, in this embodiment, jam and granules are conveyed via a jam conveying device, and yogurt is conveyed via a yogurt conveying device. The jam, granules, and yogurt are thoroughly mixed at the mixing device to ensure uniform mixing before being conveyed to the filling machine 100 for filling, thereby improving the texture of the product. Furthermore, the pressure device ensures rapid discharge from the jam conveying device, effectively improving production efficiency. The discharge port of the jam conveying device is cleaned and disinfected using cleaning and disinfection devices, achieving aseptic production and ensuring the sterility of the granules. Combined with the pressure device, the entire product is produced under aseptic conditions, meeting the corresponding quality requirements.

[0032] The specific structure of the aseptic jam and granule addition system in this embodiment is described below.

[0033] like Figure 1 As shown, the aseptic jam and granule addition system in this embodiment includes a jam conveying device, a yogurt conveying device, a mixing device, a pressure device, a cleaning device, and a sterilization device. Specifically, the jam conveying device is used to convey jam and granules, the yogurt conveying device is used to convey yogurt, and the mixing device is used to mix the jam, granules, and yogurt for delivery to the filling machine 100 for filling. Further, the pressure device is connected to the jam conveying device to accelerate the discharge of jam and granules, improving production efficiency. Correspondingly, both the cleaning device and the sterilization device are connected to the jam conveying device. The cleaning device cleans the discharge port of the jam conveying device, and the sterilization device sterilizes the discharge port of the jam conveying device. These two devices ensure the cleanliness and sterility of the discharge port of the jam conveying device, guaranteeing that production meets quality requirements.

[0034] Specifically, in this embodiment, the jam conveying device includes a sterile jam tank 11, a first discharge valve 12, a second discharge valve 13, and a first discharge pump 14. A sterile water inlet valve 111 is also provided on the top of the sterile jam tank 11. Specifically, the sterile jam tank 11 is used to store jam and granules, and the sterile water inlet valve 111 is used to convey sterile water, ensuring the stable storage of jam and granules within the sterile jam tank 11. Further, the first discharge valve 12 is connected to the outlet of the sterile jam tank 11, and is located between the sterile jam tank 11 and the second discharge valve 13. The second discharge valve 13 is located between the first discharge pump 14 and the first discharge valve 12. Thus, the jam and granules in the sterile jam tank 11 are sequentially conveyed to the first discharge pump 14 via the first discharge valve 12 and the second discharge valve 13, and then conveyed together with yogurt by the first discharge pump 14 to a mixing device for mixing, thereby realizing the conveying of jam and granules. For example, the aseptic jam jar 11 is also equipped with a temperature control element and a pressure monitoring element to monitor the internal temperature and pressure for easy adjustment.

[0035] Accordingly, the yogurt conveying device includes a sterile yogurt tank 15 and a second discharge pump 16. The sterile yogurt tank 15 is used to store yogurt, and the second discharge pump 16 can convey the yogurt to the mixing device, thereby realizing the conveying of yogurt. Further, the mixing device includes a static mixer 17, a dynamic mixing tank 18, and a feed pump 19. Optionally, the first discharge pump 14 of the jam conveying device and the second discharge pump 16 of the yogurt conveying device are both connected to the static mixer 17. The jam, granules, and yogurt are pre-mixed in the static mixer 17 first, and the mixed liquid is then conveyed to the dynamic mixing tank 18 for thorough mixing. Then, the feed pump 19 conveys the mixture to the filling machine 100 for filling. Thus, the jam, granules, and yogurt are thoroughly mixed through two mixing operations, ensuring that they are evenly mixed at the mixing device before being conveyed to the filling machine 100, thus ensuring production stability. For example, in this embodiment, the stirring speed of the dynamic mixing tank 18 is set to 10-20 rpm.

[0036] like Figure 1 As shown, in this embodiment, the pressure device includes a sterilization plate heat exchanger 21, a cooling plate heat exchanger 22, a first filter 23, and a sterile nitrogen inlet valve 24. Specifically, nitrogen is sterilized at the sterilization plate heat exchanger 21 and then cooled by the cooling plate heat exchanger 22. Further, the first filter 23 is located between the cooling plate heat exchanger 22 and the sterile nitrogen inlet valve 24 to filter the nitrogen. The filtered nitrogen then enters the aseptic jam tank 11 through the sterile nitrogen inlet valve 24 to increase the discharge speed of the aseptic jam tank 11 and ensure smooth production.

[0037] For example, a temperature control element and a pressure monitoring element are also provided between the first filter 23 and the sterile nitrogen inlet valve 24 to monitor the temperature and pressure of the nitrogen for easy adjustment. Optionally, in this embodiment, the nitrogen in the aseptic jam tank 11 is pressurized to 3-3.5 bar for conveying jam and granules. Accordingly, the temperature of the nitrogen is set to 135-138°C when it passes through the sterilization platen 21, and the temperature of the nitrogen is set to 20-30°C when it enters the cooling platen 22. The filter mesh size of the first filter 23 is less than 20 μm, and the pressure is less than or equal to 3.5 bar, thereby ensuring that the pressure generated by the nitrogen allows for smoother conveying of the jam and granules.

[0038] Optionally, in this embodiment, the cleaning device includes a main cleaning valve 31, a second filter 32, a first switching valve 33, a second switching valve 34, a cleaning reflux control valve 35, and a cleaning reflux pump 36, with the cleaning reflux pump 36 connected to the cleaning reflux outlet 361. Specifically, the second filter 32 is located between the main cleaning valve 31 and the first switching valve 33 to filter the cleaning liquid and prevent impurities in the cleaning liquid from flowing into the outlet of the aseptic jam jar 11. Optionally, the first switching valve 33 is located between the main cleaning valve 31 and the second discharge valve 13. Specifically, in this embodiment, the first switching valve 33 is located between the second filter 32 and the second discharge valve 13 and is used to transport the cleaning liquid. Further, the second switching valve 34 is located between the first discharge valve 12 and the cleaning reflux control valve 35, and the cleaning reflux pump 36 is used to discharge the cleaning liquid after cleaning, thereby enabling the cleaning device to clean the second discharge valve 13 and the first discharge valve 12.

[0039] Specifically, the cleaning fluid sequentially passes through the main cleaning valve 31, the second filter 32, the first switching valve 33, the second discharge valve 13, the first discharge valve 12, the second switching valve 34, and the cleaning return control valve 35, before being discharged by the cleaning return pump 36 to the cleaning return outlet 361, thus completing the cleaning pipeline. Exemplarily, a temperature control element and a pressure monitoring element are also provided between the second filter 32 and the first switching valve 33 to monitor the temperature and pressure of the cleaning fluid for easy adjustment. Exemplarily, the pore size of the filter screen of the second filter 32 is less than or equal to 2 mm.

[0040] Furthermore, in this embodiment, the disinfection device is provided with a sterile steam inlet 401 and a sterile steam outlet 402, and includes a third filter 41 and a sterile steam inlet valve 42. Optionally, in this embodiment, the sterile steam enters the sterile steam inlet valve 42 after being filtered by the third filter 41, thereby avoiding impurities in the sterile steam used for disinfection. Specifically, the sterile steam enters through the sterile steam inlet 401 and passes sequentially through the third filter 41, the steam inlet valve 42, the first switching valve 33, the second discharge valve 13, the first discharge valve 12, and the second switching valve 34, and is discharged at the sterile steam outlet 402, thereby disinfecting the second discharge valve 13 and the first discharge valve 12 to ensure that both meet the corresponding quality requirements in each production run.

[0041] For example, a temperature control element and a pressure monitoring element are also provided between the third filter 41 and the sterile steam inlet valve 42 to monitor the temperature and pressure of the sterile steam for easy adjustment. Optionally, the temperature of the sterile steam is set to 125-130°C, the pressure is less than or equal to 3.4 bar, and the pore size of the filter screen of the third filter 41 is less than 20 μm.

[0042] In summary, in this embodiment, the aseptic jam and granule addition system achieves rapid discharge through nitrogen pressure, and utilizes the static mixer 17 and dynamic mixing tank 18 to achieve uniform mixing of jam, granules, and yogurt. The first discharge valve 12 and the second discharge valve 13, the discharge port connection valve of the aseptic jam tank 11, and the main conveying pipeline are cleaned using a cleaning solution, and sterilization is achieved with the assistance of aseptic steam. Furthermore, the cleaning solution effectively filters impurities through the second filter 32, and the aseptic steam effectively filters impurities through the third filter 41, preventing impurities from entering.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model.
