[0003] Currently, in the production process of jam, there is a system that uses aseptic docking to achieve online addition. However, the cross valve of this system uses steam sterilization at 105°C - 110°C. Since heat-sensitive materials will denature at high temperatures, it cannot be used for heat-sensitive materials.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this utility model. The terms used herein in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0061] Such as Figure 1 And Figure 2As shown in the figure, the present utility model provides a sterile material docking system, which includes: a cross valve unit, which includes a cross pipeline 20 and a first barrier valve 21, a second barrier valve 22, a third barrier valve 23, and a fourth barrier valve 24 respectively connected to the four ends of the cross pipeline 20. The cross pipeline 20 communicates with each barrier valve (i.e., the first barrier valve 21, the second barrier valve 22, the third barrier valve 23, and the fourth barrier valve 24); a sterile tank 10 for containing the material to be added, and the sterile tank 10 is connected to the first barrier valve 21; a feed pipeline 30, which is connected to the second barrier valve 22; a disinfection barrier pipeline 40 for introducing steam into the cross valve unit, and the disinfection barrier pipeline 40 is connected to the third barrier valve 23 and the fourth barrier valve 24; and a material incoming pipeline 50, which is connected to the feed pipeline 30.

[0062] For the sterile material docking system described in the present utility model, the material to be added is added into the pipeline through the sterile tank 10. The capacity of the sterile tank 10 is relatively large, and it can be added online for a long time without frequently replacing disposable consumables, reducing the production operation cost while reducing the risk of material contamination.

[0063] For the sterile material docking system described in the present utility model, while disinfecting and sterilizing the pipeline through the disinfection barrier pipeline 40 connected to the cross valve unit, it can also form a double protection of steam plus condensed water for the cross valve unit, resulting in small heat loss of the heat-sensitive material, preventing the heat-sensitive material from coking and blocking the sterile pipeline due to excessive barrier temperature, and also avoiding the risk of slightly coked material entering the product.

[0064] The following will detail the specific structures of each part of the sterile material docking system described in the present utility model, as well as the pipeline connection relationships between each part.

[0065] As Figure 1 and Figure 2 shown, the sterile material docking system described in the present utility model is provided with a cross valve unit, and the cross valve unit is a valve body pipeline structure for realizing the sterile docking between the sterile tank 10 and the sterile material pipeline.

[0066] The cross valve unit includes a cross pipeline 20 and four barrier valves. Among them, the cross pipeline 20 is two straight pipes that are perpendicular to each other and connected together. The two straight pipes communicate with each other, and a barrier valve is connected to the end of each of the two straight pipes. The four barrier valves are respectively the first barrier valve 21, the second barrier valve 22, the third barrier valve 23, and the fourth barrier valve 24. In the state where all four barrier valves are closed, a relatively closed cross chamber is formed in the two straight pipes.

[0067] Further, as Figure 1As shown, the first barrier valve 21 is connected to the sterile tank 10 through a pipeline. The sterile tank 10 contains the material to be added to the sterile material pipeline. This material to be added is usually a heat-sensitive material with high requirements for the external environment (temperature, cleanliness, etc.). Driven by air pressure, the material to be added in the sterile tank 10 can enter the cross valve unit through the pipeline. The second barrier valve 22 is connected to the incoming material pipeline 50 through the feed pipeline 30. The material to be added in the cross valve unit can flow into the feed pipeline 30 through the second barrier valve 22. The incoming material pipeline 50 is filled with sterile material; the material to be added in the feed pipeline 30 and the sterile material in the incoming material pipeline 50 can be mixed at the pipeline docking point, that is, the material to be added is added to the sterile material. The mixed sterile material continues to flow forward and then enters the downstream filling machine (not shown in the figure) for filling operations.

[0068] As Figure 1 and Figure 2 shown, in order to ensure that the feed pipeline 30 maintains a sterile environment during material transportation, the material sterile docking system of the present invention further includes a disinfection barrier pipeline 40. The disinfection barrier pipeline 40 is connected to the cross valve unit for sterilization and forming a condensate barrier.

[0069] The disinfection barrier pipeline 40 is respectively connected to the third barrier valve 23 and the fourth barrier valve 24. The inlet of the disinfection barrier pipeline 40 is provided with a parallel high-pressure steam branch pipe and a low-pressure steam branch pipe. The high-pressure steam branch pipe is connected to a high-pressure steam source and is provided with a tenth valve 010 thereon. The tenth valve 010 is used to control the conduction and cut-off of this branch pipe. The low-pressure steam branch pipe is connected to a low-pressure steam source and is provided with an eleventh valve 011 thereon. The eleventh valve 011 is used to control the conduction and cut-off of this branch pipe.

[0070] When it is necessary to perform sterilization treatment on the cross valve unit, open the tenth valve 010, introduce high-pressure steam (about 2.7 bar) into the disinfection barrier pipeline 40, and at the same time open the third barrier valve 23, the fourth barrier valve 24, and the second barrier valve 22 to perform high-temperature sterilization on the cross valve unit and the feed pipeline 30 through the steam.

[0071] When it is necessary to form a condensate barrier outside the cross valve unit, open the eleventh valve 011, introduce low-pressure steam (0.5 bar - 1 bar) into the disinfection barrier pipeline 40, and at the same time close the third barrier valve 23 and the fourth barrier valve 24. The low-pressure steam liquefies in the disinfection barrier pipeline 40 near the third barrier valve 23 and the fourth barrier valve 24, and then a section of condensate pipeline is formed outside the third barrier valve 23 and the fourth barrier valve 24 to form a condensate barrier for the cross valve unit and maintain the sterile environment inside the cross valve unit.

[0072] The structure and technical effects of the preferred embodiment of the material sterile docking system of the present invention will be further described in detail below.

[0073] According to an embodiment of the present utility model, as Figure 2 shown, the first barrier valve 21 and the second barrier valve 22 are oppositely arranged, and the third barrier valve 23 and the fourth barrier valve 24 are oppositely arranged.

[0074] Specifically, the first barrier valve 21 and the second barrier valve 22 are respectively connected to two ends of the same straight pipe, and the third barrier valve 23 and the fourth barrier valve 24 are respectively connected to two ends of another straight pipe; the position design of the above-mentioned barrier valves can improve the smoothness of the flow of the material to be added in the cross valve unit; a condensate protection is formed on both sides of the material to be added, and the aseptic barrier effect is better.

[0075] Preferably, a first temperature sensor 80 is provided on the cross pipeline 20 in the cross valve unit, and the first temperature sensor 80 can monitor the temperature in the cross pipeline 20.

[0076] According to an embodiment of the present utility model, as Figure 1 shown, a condenser is provided on the disinfection barrier pipeline 40, and the condenser is connected with a first cooling water pipeline 45. The condenser is used for cooling the low-pressure steam in the sterilization pipeline 60, so that the low-pressure steam condenses into condensate, thereby forming a condensate barrier for the cross valve unit; the cooling water flowing in the first cooling water pipeline 45 serves as a coolant for the condenser.

[0077] Specifically, as Figure 2 shown, the disinfection barrier pipeline 40 has a first branch pipe 41 connected to the third barrier valve 23 and a second branch pipe 42 connected to the fourth barrier valve 24. A first condenser 43 is provided on the first branch pipe 41, and the pipeline between the first condenser 43 and the third barrier valve 23 forms a first condensate barrier section 25; a fifth valve 005 and a second condenser 44 are provided on the second branch pipe 42. The fourth barrier valve 24 is connected with a first valve 001 through a pipeline. The second branch pipe 42 is connected with the pipeline between the fourth barrier valve 24 and the first valve 001. The pipeline between the second condenser 44, the fourth barrier valve 24 and the first valve 001 forms a second condensate barrier section 26. The first cooling water pipeline 45 has a main pipe and two branch pipes. A sixth valve 006 for controlling the on-off of the first cooling water pipeline 45 is provided on the main pipe, and the two branch pipes are respectively connected to the first condenser 43 and the second condenser 44 to provide cooling water for the two condensers respectively.

[0078] A first condensate barrier section 25 is formed on one side of the third barrier valve 23 through the first condenser 43, and a second condensate barrier section 26 is formed on one side of the fourth barrier valve 24 through the second condenser 44, ensuring a sterile environment at the cross valve unit and avoiding excessive barrier temperature at the cross valve unit. At the same time, low-pressure steam still flows in the pipeline on one side of the first condenser 43, and low-pressure steam also flows in the pipeline on one side of the second condenser 44, thereby forming a dual protection of steam and condensate for the third barrier valve 23 and the fourth barrier valve 24.

[0079] Further, as Figure 2 shown, the first valve 001 is connected to the second valve 002 through a pipeline, and the disinfection barrier pipeline 40 is also connected to the pipeline between the first valve 001 and the second valve 002; specifically, the second branch pipe 42 further branches out a branch pipe to connect to the pipeline between the first valve 001 and the second valve 002, for introducing low-pressure steam into the pipeline between the first valve 001 and the second valve 002, so that one side of the first valve 001 is condensate and the other side is steam, thereby forming a dual protection of steam and condensate. The second valve 002 is connected to the first discharge pipeline 46, and the twelfth valve 012 is provided on the first discharge pipeline 46, and the twelfth valve 012 controls the on and off of the first discharge pipeline 46; when sterilization treatment is carried out through the disinfection barrier pipeline 40, the first valve 001, the second valve 002 and the twelfth valve 012 are opened, and the high-pressure steam entering the cross valve unit can be discharged through the first discharge pipeline 46.

[0080] Preferably, as Figure 2 shown, a second temperature sensor 81 is provided on the pipeline between the fourth barrier valve 24 and the first valve 001, and the second temperature sensor 81 can monitor the temperature in the pipeline at this position; a third temperature sensor 82 is also provided on the first discharge pipeline 46, and the third temperature sensor 82 can monitor the temperature in the first discharge pipeline 46.

[0081] According to an embodiment of the present invention, as Figure 1 shown, the material aseptic docking system further includes: a cross valve sterilization unit, having a sterilization pipeline 60 communicated with the third barrier valve 23 and the fourth barrier valve 24, and a sterile water storage tank 61 and a peracetic acid storage tank 62 are provided on the sterilization pipeline 60.

[0082] The cross valve sterilization unit is used for re-disinfecting the cross valve unit after docking with the aseptic tank 10; a set of sterile water system is formed by the sterile water storage tank 61 and the sterilization pipeline 60, and the cavity in the cross valve unit is rinsed with sterile water through the sterile water; the peracetic acid storage tank 62 and the sterilization pipeline 60 form a set of peracetic acid disinfection system, and the cavity in the cross valve unit is sterilized and disinfected with peracetic acid, so as to realize the disinfection treatment after the aseptic tank 10 is docked with the cross valve unit.

[0083] It should be noted that the process of introducing high-pressure steam into the disinfection barrier pipeline 40 for sterilization treatment is usually before the first barrier valve 21 is connected to the sterile tank 10, that is, the cleaning and sterilization treatment is carried out before the aseptic docking; during the aseptic docking process, when the sterile tank 10 is connected to the first barrier valve 21, exposure points will be generated. Therefore, it is necessary to sterilize the cross-valve unit again after docking. The above cross-valve sterilization unit is a sterilization device for after aseptic docking.

[0084] Specifically, as Figure 1 shown, one end of the sterilization pipeline 60 is connected to the disinfection barrier pipeline 40, and through the disinfection barrier pipeline 40, the sterilization pipeline 60 is connected to the third barrier valve 23 and the fourth barrier valve 24 in the cross-valve unit. Connecting the sterilization pipeline 60 directly to the disinfection barrier pipeline 40 eliminates the need to separately connect the sterilization pipeline 60 to the third barrier valve 23 and the fourth barrier valve 24, simplifying the pipeline structure in the system. At the same time, the disinfection barrier pipeline 40 can also be sterilized through the sterilization pipeline 60.

[0085] Furthermore, a third valve 003 is provided at the end of the sterilization pipeline 60 connected to the disinfection barrier pipeline 40. The third valve 003 is used to control the on and off between the sterilization pipeline 60 and the disinfection barrier pipeline 40. The sterile water storage tank 61 is connected to the sterile water preparation device 65. The sterile water generated by the sterile water preparation device 65 can be stored in the sterile water storage tank 61 to supplement the consumption of sterile water in the sterile water storage tank 61. A seventh valve 007 is provided between the sterile water storage tank 61 and the sterilization pipeline 60. The seventh valve 007 can control the on and off between the sterile water storage tank 61 and the sterilization pipeline 60; a ninth valve 009 is provided between the peracetic acid storage tank 62 and the sterilization pipeline 60. The ninth valve 009 is used to control the on and off between the peracetic acid storage tank 62 and the sterilization pipeline 60.

[0086] Preferably, an eighth valve 008 is provided on the sterilization pipeline 60 between the seventh valve 007 and the ninth valve 009. The eighth valve 008 is used to control the on and off of the sterilization pipeline 60.

[0087] According to an embodiment of the present invention, as Figure 1 shown, a first drive pump 63 and a heater 64 are provided on the sterilization pipeline 60. The first drive pump 63 is used to drive the sterile water or peracetic acid in the sterilization pipeline 60 to flow towards the cross-valve unit, and the heater 64 is used to heat the sterile water or peracetic acid in the sterilization pipeline 60; among them, the heater 64 can heat the sterile water in the sterilization pipeline 60 to about 55 °C and then introduce it into the cross-valve unit for cleaning, and can also heat the peracetic acid in the sterilization pipeline 60 to about 55 °C and then introduce it into the cross-valve unit for disinfection and sterilization.

[0088] According to an embodiment of the present invention, asFigure 1 As shown, a peracetic acid reflux pipeline 51 is provided between the peracetic acid storage tank 62 and the cross valve unit. A circulating disinfection loop is formed between the cross valve unit and the peracetic acid storage tank 62 through the sterilization pipeline 60 and the peracetic acid reflux pipeline 51, which can save disinfectant and improve the sterilization effect on the cross valve unit.

[0089] Specifically, as Figure 1 shown, one end of the peracetic acid reflux pipeline 51 is connected to the second valve 002, and the other end is connected to the top of the peracetic acid storage tank 62; when disinfecting and sterilizing the cross valve unit with peracetic acid, the ninth valve 009, the third valve 003, the third barrier valve 23, the fourth barrier valve 24, the first valve 001 and the second valve 002 are all opened, and the peracetic acid in the peracetic acid storage tank 62 passes through the sterilization pipeline 60, the disinfection barrier pipeline 40, the cross valve unit, the first valve 001, the second valve 002 and the peracetic acid reflux pipeline 51 in sequence and then flows back into the peracetic acid storage tank 62.

[0090] According to an embodiment of the present invention, as Figure 1 shown, the material aseptic docking system further includes: a discharge pipeline 70, connected to the feed pipeline 30, along the flow direction of the material in the feed pipeline 30, the discharge pipeline 70 is arranged upstream of the feed pipeline 30, and the incoming material pipeline 50 is arranged downstream of the feed pipeline 30.

[0091] The discharge pipeline 70 is used for the separate discharge of the feed pipeline 30. When it is not necessary to mix the materials in the feed pipeline 30 and the incoming material pipeline 50, the connection between the feed pipeline 30 and the incoming material pipeline 50 can be shut off, so that the material to be added in the aseptic tank 10 can be discharged through the feed pipeline 30 and the discharge pipeline 70.

[0092] According to an embodiment of the present invention, as Figure 1 and Figure 3 shown, one end of the discharge pipeline 70 is connected with an end valve group unit, and the end valve group unit includes: a discharge valve 71, connected to the end of the discharge pipeline 70; a barrier pipeline 72, the discharge valve 71 is arranged on the barrier pipeline 72, and fifth barrier valves 73 and sixth barrier valves 74 are arranged at both ends of the barrier pipeline 72; a steam pipeline 75 for introducing steam into the barrier pipeline 72, and the steam pipeline 75 is connected to the fifth barrier valve 73 and the sixth barrier valve 74.

[0093] The end valve group unit can form a condensate barrier at the discharge valve 71, so that the discharge pipeline 70 is not polluted by the outside, and the aseptic environment during the discharge operation is guaranteed.

[0094] Specifically, as Figure 1 and Figure 3As shown, one end of the discharge pipeline 70 is connected to the feed pipeline 30, and the other end is connected with a discharge valve 71. The discharge valve 71 is used to control the on and off of the discharge pipeline 70. When discharging operation is required, the discharge valve 71 is opened, and the material in the discharge pipeline 70 can be discharged through the discharge valve 71. When normal material addition operation is carried out, the discharge valve 71 is in a closed state. A thirteenth valve 013 is provided on the steam pipeline 75, and the thirteenth valve 013 is used to control the on and off of the steam pipeline 75.

[0095] To ensure a sterile environment at the discharge valve 71, a barrier pipeline 72 for forming a condensate barrier passes through the discharge valve 71. The barrier pipeline 72 is a straight pipe, and both ends of the straight pipe are respectively connected with a fifth barrier valve 73 and a sixth barrier valve 74. The steam pipeline 75 is respectively connected with the fifth barrier valve 73 and the sixth barrier valve 74. When it is necessary to form a condensate barrier for the discharge valve 71, low-pressure steam is introduced into the steam pipeline 75, and the low-pressure steam liquefies in the barrier pipeline 72 between the fifth barrier valve 73 and the sixth barrier valve 74, and then a section of condensate pipeline is formed on the barrier pipeline 72 to form a condensate barrier for the discharge valve 71 and maintain a sterile environment in the end valve group unit.

[0096] According to an embodiment of the present invention, as Figure 3 shown, a third condenser 76 is provided on the pipeline between the discharge valve 71 and the fifth barrier valve 73. The third condenser 76 is connected with a second cooling water pipeline 77, and the pipeline between the third condenser 76 and the sixth barrier valve 74 forms a third condensate barrier section 78. A third condensate barrier section 78 is formed at the discharge valve 71 through the third condenser 76 to ensure a sterile environment at the end of the discharge pipeline 70. A fourteenth valve 014 is provided on the second cooling water pipeline 77, and the fourteenth valve 014 is used to control the on and off of the second cooling water pipeline 77.

[0097] Specifically, as Figure 3As shown, the steam pipeline 75 has a third branch pipe 751 connected to the fifth barrier valve 73 and a fourth branch pipe 752 connected to the sixth barrier valve 74. The sixth barrier valve 74 is connected to a second discharge pipeline 79, and the fourth branch pipe 752 is connected to the second discharge pipeline 79. Among them, when forming a condensate barrier, the fifth barrier valve 73 is opened, the sixth barrier valve 74 is closed, and at the same time, low-pressure steam is introduced into the steam pipeline 75. The steam entering the third branch pipe 751 enters the barrier pipeline 72 through the fifth barrier valve 73 and is liquefied into condensate under the action of the third condenser 76 on the barrier pipeline 72. Since the sixth barrier valve 74 is closed, a third condensate barrier section 78 filled with condensate is formed between the sixth barrier valve 74 and the third condenser 76, and the discharge valve 71 is located in the third condensate barrier section 78. One side of the third condenser 76 is condensate, and the other side is steam. One side of the sixth barrier valve 74 is condensate, and the other side is steam, thereby forming a double protection of steam and condensate for the discharge valve 71.

[0098] Further, as Figure 3 shown, a fifteenth valve 015 is provided on the second discharge pipeline 70, and the fifteenth valve 015 is used to control the conduction and cut-off of the second discharge pipeline 70; when sterilizing the cross valve unit and the corresponding pipelines through the disinfection barrier pipeline 40, the discharge valve 71, the sixth barrier valve 74, and the fifteenth valve 015 are opened, and high-pressure steam can enter the end valve group unit through the feed pipeline 30 and the discharge pipeline 70, thereby sterilizing the end valve group unit, and then discharging through the second discharge pipeline 79.

[0099] Preferably, as Figure 3 shown, a fourth temperature sensor 83 is provided on the barrier pipeline 72 between the fifth barrier valve 73 and the sixth barrier valve 74, and the fourth temperature sensor 83 is used to monitor the temperature in the barrier pipeline 72; a fifth temperature sensor 84 is provided on the second discharge pipeline 79, and the fifth temperature sensor 84 is used to monitor the temperature in the second discharge pipeline 79.

[0100] According to an embodiment of the present invention, as Figure 3 shown, a second driving pump 31 is provided on the feed pipeline 30, and a fourth valve 004 is provided on the feed pipeline 30 between the discharge pipeline 70 and the incoming material pipeline 50. The second driving pump 31 can drive the material in the feed pipeline 30 to be transported forward; the fourth valve 004 can control the conduction and cut-off between the feed pipeline 30 and the incoming material pipeline 50, thereby controlling the system to switch between the mixing operation and the discharging operation.
