[0027] Generally, the pre-treatment pipeline is directly connected with the filling machine, the raw material in the pre-treatment pipeline enters the filling machine and is filled into the package or container, and then the package or container is packaged to form a product. However, if one of the pre-treatment pipeline or the filling machine is contaminated during production, the production needs to be stopped, and the pre-treatment pipeline and the filling machine need to be sterilized and cleaned together, which makes the production efficiency low.

[0028] The embodiments of the present application provide a filling system. The filling system comprises a filling device, a feeding pipeline and a valve assembly. The valve assembly comprises a first isolation valve and a second isolation valve arranged between the filling device and the feeding pipeline. The first isolation valve comprises a first valve cavity, and the second isolation valve comprises a second valve cavity. The first isolation valve is connected with the filling device and the second isolation valve respectively, and the second isolation valve is connected with the feeding pipeline and the first isolation valve respectively. The first isolation valve and the second isolation valve are arranged as follows: when the first isolation valve and the second isolation valve are both in an open position, the feeding pipeline and the filling device form a passage, so that the raw material in the feeding pipeline enters the filling device through the second valve cavity and the first valve cavity; when the second isolation valve is in a closed position, the feeding pipeline and the filling device are isolated, and the raw material cannot enter the filling device.

[0029] In the filling system provided by the embodiments of the present application, the communication or disconnection of the filling device and the feeding pipeline can be realized by arranging the valve assembly. Moreover, by arranging the first isolation valve with the first valve cavity and the second isolation valve with the second valve cavity, the connection of the filling device, the pre-treatment device and the pipeline can be more flexible, which not only facilitates the connection or isolation between the devices, but also facilitates the sterilization of the filling device and the pipeline, the further isolation of the pre-treatment device and the like, thereby ensuring the production efficiency of the system.

[0030] The filling system provided by the embodiment of the present application will be described in detail below with reference to the drawings.

[0031] The embodiment of the present application provides a filling system. Figure 1 A schematic diagram of the filling system provided by the embodiment of the present application is shown in the figure. Figure 1 As shown in the figure, the filling system comprises a filling device 100, a feed pipe 200 and a valve assembly. The valve assembly comprises a first isolation valve V01 and a second isolation valve V02 arranged between the filling device 100 and the feed pipe 200. The first isolation valve V01 comprises a first valve cavity V011, and the second isolation valve V02 comprises a second valve cavity V021. The first isolation valve V01 is connected to the filling device 100 and the second isolation valve V02 respectively, and the second isolation valve V02 is connected to the feed pipe 200 and the first isolation valve V01 respectively.

[0032] As shown in the figure, Figure 1 The first isolation valve V01 and the second isolation valve V02 are arranged as follows: when the first isolation valve V01 and the second isolation valve V02 are both in the open position, the feed pipe 200 and the filling device 100 form a passage, so that the raw materials in the feed pipe 200 enter the filling device 100 through the second valve cavity V021 and the first valve cavity V011; when the second isolation valve V02 is in the closed position, the feed pipe 200 and the filling device 100 are isolated, and the raw materials cannot enter the filling device 100.

[0033] As shown in the figure, Figure 1As shown in the filling system provided by the embodiment of the present application, the valve assembly is arranged between the filling device 100 and the feed pipeline 200, and the valve assembly is arranged to realize the communication or disconnection between the filling device 100 and the feed pipeline 200. For example, the feed pipeline 200 can be connected with the pre-treatment device 001, and thus the valve assembly is arranged to realize the communication or disconnection between the filling device 100 and the pre-treatment device 001. For example, the pre-treatment device 001 is used to provide raw materials. For example, the raw materials can be milk, beverages and the like. For example, when the raw materials need to be filled, the two isolation valves of the valve assembly are arranged in the open position, and the feed pipeline 200 and the filling device 100 form a passage. For example, when the filling device 100 is in a bacteria-carrying state, in order to avoid the pre-treatment device 001 being contaminated, the second isolation valve V02 is arranged in the closed position, so that the filling device 100 and the feed pipeline 200 are isolated, at this time, the bacteria-carrying device can be sterilized, and the non-bacteria-carrying device can be connected with other devices for continuous production, so that the influence on production can be minimized. For example, when one of the filling device 100 or the pre-treatment device 001 needs to be overhauled, the second isolation valve V02 can also be arranged in the closed position to isolate the filling device 100 and the feed pipeline 200, at this time, the overhaul of one will not affect the other, so that the influence on production can be minimized.

[0034] As Figure 1 shown, the valve assembly of the filling system provided by the embodiment of the present application comprises a first isolation valve V01 and a second isolation valve V02, the first isolation valve V01 comprises a first valve cavity V011, and the second isolation valve V02 comprises a second valve cavity V021. For example, when the filling device 100 is bacteria-carrying, the second isolation valve V02 is arranged in the closed position to isolate the feed pipeline 200 and the filling device 100, so as to facilitate independent cleaning or sterilization of the filling device 100. Further, by arranging the first isolation valve V01 in the open position or the closed position, on the one hand, the filling device 100, the first valve cavity V011 and the second valve cavity V021 can be sterilized through the pipeline, and on the other hand, steam barrier can be introduced into the pipeline and the second valve cavity V021 to isolate the pre-treatment device 001, so as to avoid the pre-treatment device 001 being contaminated. Therefore, by arranging the first isolation valve V01 with the first valve cavity V011 and the second isolation valve V02 with the second valve cavity V021, the connection of the filling device 100, the pre-treatment device 001 and the pipeline can be more flexible, not only facilitating the connection or isolation between the devices, but also facilitating the sterilization of the filling device 100 and the pipeline and the further isolation of the pre-treatment device 001, so as to ensure the production efficiency of the system.

[0035] In some examples, as Figure 1As shown, the filling system further comprises a first delivery line 310 connected with the first isolating valve V01 to form a passage for the first delivery line 310 through the first valve cavity V011 to the filling device 100. Thus, the filling device 100 can be cleaned and sterilized by the medium in the first delivery line 310. For example, the first isolating valve V01 and the second isolating valve V02 can be configured such that when the first isolating valve V01 and the second isolating valve V02 are both in the closed position, the medium in the first delivery line 310 enters the filling device 100 through the first valve cavity V011. For example, the medium in the first delivery line 310 can be cleaning medium for cleaning or sterilizing medium for sterilization. For example, the medium can be condensed water, steam, alkaline water or acid water, etc., which will not be repeated here.

[0036] In some examples, as shown in FIG. 1, Figure 1 As shown, the filling system further comprises a first delivery line 310 connected with the first isolating valve V01 to form a passage for the first delivery line 310 through the first valve cavity V011 to the filling device 100. Thus, the filling device 100 can be cleaned and sterilized by the medium in the first delivery line 310. For example, the first isolating valve V01 and the second isolating valve V02 can be configured such that when the first isolating valve V01 and the second isolating valve V02 are both in the closed position, the medium in the first delivery line 310 enters the filling device 100 through the first valve cavity V011. For example, the medium in the first delivery line 310 can be cleaning medium for cleaning or sterilizing medium for sterilization. For example, the medium can be condensed water, steam, alkaline water or acid water, etc., which will not be repeated here.

[0037] In some examples, as shown in FIG. 1, Figure 1 As shown, the filling system further comprises a first delivery line 310 connected with the first isolating valve V01 to form a passage for the first delivery line 310 through the first valve cavity V011 to the filling device 100. Thus, the filling device 100 can be cleaned and sterilized by the medium in the first delivery line 310. For example, the first isolating valve V01 and the second isolating valve V02 can be configured such that when the first isolating valve V01 and the second isolating valve V02 are both in the closed position, the medium in the first delivery line 310 enters the filling device 100 through the first valve cavity V011. For example, the medium in the first delivery line 310 can be cleaning medium for cleaning or sterilizing medium for sterilization. For example, the medium can be condensed water, steam, alkaline water or acid water, etc., which will not be repeated here.

[0038] In some examples, as shown in FIG. 1, Figure 1As shown, the valve assembly also includes a first switching valve V03 and a second switching valve V04. The first switching valve V03 is located at the end of the second delivery line 320 near the second isolation valve V02 to control the connection or disconnection between the second delivery line 320 and the second valve chamber V021. The second switching valve V04 is located at the end of the first discharge line 410 near the second isolation valve V02 to control the connection or disconnection between the first discharge line 410 and the second isolation valve V02. The arrangement of the first switching valve V03 and the second switching valve V04 allows for flexible connection or disconnection of the second isolation valve V02 with each line, accommodating a wider range of needs.

[0039] In some examples, such as Figure 1 As shown, the filling system also includes a second discharge pipe 420. The second discharge pipe 420 is connected to the second delivery pipe 320, and the connection point P01 between the second discharge pipe 420 and the second delivery pipe 320 is located on the side of the first switching valve V03 away from the second isolation valve V02. For example, the first switching valve V03 includes a first side and a second side in the delivery path direction of the second delivery pipe 320, the second isolation valve V02 is connected to the first switching valve V03 on the first side, and the second discharge pipe 420 is connected to the second delivery pipe 320 on the second side of the first switching valve V03.

[0040] In some examples, such as Figure 1 As shown, the valve assembly can be configured such that when both the first isolation valve V01 and the second isolation valve V02 are in the open position, and both the first switching valve V03 and the second switching valve V04 are in the closed position, the medium in the second delivery pipeline 320 is isolated at the first switching valve V03 and enters the second discharge pipeline 420. For example, the medium in the second delivery pipeline 320 can be steam, thereby forming a steam barrier on the second side of the first switching valve V03. In this example, when the first isolation valve V01 and the second isolation valve V02 are in the open position, the raw material in the feed pipeline 200 enters the filling equipment 100 through the first valve chamber V011 and the second valve chamber V021. This steam barrier can further isolate the filling raw material from the outside world and simultaneously sterilize it, based on the first switching valve V03, preventing the filling raw material from being contaminated by the outside world.

[0041] For example, the temperature of the steam in this invention can be greater than or equal to 100 degrees Celsius. For example, the temperature of the steam can be greater than or equal to 110 degrees Celsius. For example, the temperature of the steam can be greater than or equal to 120 degrees Celsius. This invention does not limit the steam temperature; the steam temperature can be set according to the bacterial load. For example, if one piece of equipment is bacterially contaminated, the steam temperature can be increased to better achieve the isolation and sterilization effects. For example, if neither piece of equipment on either side of the steam barrier is bacterially contaminated, the steam temperature can be appropriately decreased.

[0042] In some examples, such as Figure 1 As shown, the valve assembly can be configured such that when both the first isolation valve V01 and the second isolation valve V02 are in the closed position, and the first switching valve V03 is in the open position and the second switching valve V04 is in the closed position, the medium in the second delivery pipeline 320 is isolated at the second switching valve V04 after passing through the first switching valve V03 and the second valve chamber V021 (i.e., it flows back to the first switching valve V03 after being blocked by the second switching valve V04) and enters the second discharge pipeline 420. For example, the medium in the second delivery pipeline 320 can be steam, thereby forming a steam barrier in the second delivery pipeline 320 and the second valve chamber V021 of the second isolation valve V02. This steam barrier, with the first isolation valve V01 and the second isolation valve V02 in the closed position, further isolates the feed pipeline 200 from the filling equipment 100 and simultaneously sterilizes it, preventing cross-contamination between the pretreatment equipment 001 and the filling equipment 100. Thus, the uncontaminated equipment can continue operating, while the contaminated equipment can be sterilized without affecting each other, improving work efficiency. For example, when the pretreatment equipment 001 is contaminated, the steam barrier can isolate it and simultaneously sterilize it to protect the filling equipment 100. Similarly, when the filling equipment 100 is contaminated, the steam barrier can isolate it and simultaneously sterilize it to protect the pretreatment equipment 001.

[0043] In some examples, such as Figure 1As shown, the valve assembly further includes a first discharge valve V05 disposed on the second discharge line 420, the first discharge valve V05 is configured to maintain the medium isolated by the first switching valve V03 or the second switching valve V04 and in the second delivery line 320 or the second valve cavity V021 when the first discharge valve V05 is in a closed position. When the first discharge valve V05 is in an open position, the medium isolated by the first switching valve V03 or the second switching valve V04 and in the second discharge line 420 passes through the first discharge valve V05 and is discharged. For example, the medium in the second delivery line 320 or the second valve cavity V021 is steam, as described above, the steam in the second delivery line 320 or the second valve cavity V021 forms a steam barrier to further isolate and sterilize. The configuration of the first discharge valve V05 can ensure that the steam barrier is at a high temperature, thereby maintaining the isolation and sterilization effects. For example, when the temperature of the steam in the second delivery line 320 is lower than a set temperature, the first discharge valve V05 can be in an open position, so that the condensed water formed by the cooling of the steam in the second delivery line 320 can flow and be discharged through the second discharge line 420, and new high-temperature steam can flow into the second delivery line 320. When the temperature of the steam in the second delivery line 320 reaches or exceeds the set temperature, the first discharge valve V05 can be in a closed position. For example, the set temperature can be 120 degrees. For example, when the time of the first discharge valve V05 in the closed position exceeds a set time, the first discharge valve V05 can be in an open position, and after a certain period of time, the first discharge valve V05 can be in a closed position. For example, the set time can be 1 hour. It should be noted that when the first discharge valve V05 is in the closed position and the open position, steam is always present in the second delivery line 320 to form a steam barrier.

[0044] In some examples, as Figure 1 As shown, the filling system further includes a first sensor S01 disposed on the second delivery line 320 for measuring the temperature of the medium in the second delivery line 320. Thus, the opening and closing of the first discharge valve V05 can be controlled to better enable the steam barrier to isolate and sterilize.

[0045] Next, different working processes of the filling system shown in Figure 1 As shown, the filling system further includes a first sensor S01 disposed on the second delivery line 320 for measuring the temperature of the medium in the second delivery line 320. Thus, the opening and closing of the first discharge valve V05 can be controlled to better enable the steam barrier to isolate and sterilize.

[0046] Figure 2 For Figure 1 As shown, the filling system further includes a first sensor S01 disposed on the second delivery line 320 for measuring the temperature of the medium in the second delivery line 320. Thus, the opening and closing of the first discharge valve V05 can be controlled to better enable the steam barrier to isolate and sterilize. Figure 1 and Figure 2As shown, when both the first isolation valve V01 and the second isolation valve V02 are in the closed position, the feed pipeline 200 and the filling equipment 100 are isolated, and the filling system is not performing a filling operation. At this time, both the first switching valve V03 and the second switching valve V04 can be in the open position. The second conveying pipeline 320 forms a passage with the first discharge pipeline 410 through the second valve chamber V021. The medium in the second conveying pipeline 320 is discharged through the first switching valve V03, the second valve chamber V021, the second switching valve V04, and the first discharge pipeline 410. (See [reference]) Figure 2 The path R01 in the diagram. For example, the medium in the second delivery line 320 can be condensate for pre-flushing the valves, valve chambers, and pipelines along the path. It should be noted that, for clearer display of each line, Figure 2 The labels for valves, equipment, and pipelines are omitted; please refer to [link / reference needed]. Figure 1 The workflow diagrams below are similar and will not be repeated here.

[0047] For example, such as Figure 1 and Figure 2 As shown, when both the first isolation valve V01 and the second isolation valve V02 are in the closed position, the first delivery pipeline 310 forms a passage with the filling equipment 100 through the first valve chamber V011. The medium in the first delivery pipeline 310 is discharged through the first valve chamber V011 and the filling equipment 100. (See Figure 100) Figure 2 The path R02 in the first delivery pipeline 310 can be alkaline water, acidic water, or steam. For example, the filling equipment 100 can be cleaned first by using alkaline water or acidic water in the first delivery pipeline 310. Then, the filling equipment 100 can be sterilized by using steam in the first delivery pipeline 310.

[0048] For example, such as Figure 1 and Figure 2 As shown, when the filling equipment 100 is contaminated with bacteria, the first isolation valve V01 and the second isolation valve V02 are both set to the closed position to isolate the feed pipe 200 and the filling equipment 100 from each other. At this time, the first switching valve V03 and the second switching valve V04 can both be in the open position, and the medium in the second conveying pipe 320 can be steam. The steam forms a steam barrier in the second conveying pipe 320, the second valve chamber V021, and the first discharge pipe 410. (See [reference]). Figure 2 In the circuit R01, with the first isolation valve V01 and the second isolation valve V02 in the closed position, it can further serve as an isolation and sterilization mechanism, preventing contamination of the other sterile equipment by a contaminated device and avoiding disruption to continued production. For example, if one device is contaminated, the other can be connected to other equipment to continue production.

[0049] Figure 3 forFigure 1 The diagram shows another workflow of the filling system. (See diagram for example.) Figure 1 and Figure 3 As shown, when the second isolation valve V02 is in the closed position, the feed line 200 and the filling equipment 100 are isolated, and the filling system is not performing a filling operation. For example, the first isolation valve V01 can be in the open position, and the first delivery line 310 forms a passage with the first valve chamber V011, the second valve chamber V021, and the first discharge line 410. The medium in the first delivery line 310 is discharged through the first valve chamber V011, the second valve chamber V021, and the first discharge line 410. See [reference needed]. Figure 3 The path R03 in the process. For example, the first valve chamber V011, the second valve chamber V021, and the first discharge pipe 410 can be cleaned first by alkaline water or acidic water in the first delivery pipe 310. Then, the first valve chamber V011, the second valve chamber V021, and the first discharge pipe 410 can be sterilized by steam in the first delivery pipe 310.

[0050] Figure 4 for Figure 1 The diagram shows another workflow of the filling system. (See diagram for example.) Figure 1 and Figure 4 As shown, both the first isolation valve V01 and the second isolation valve V02 are in the open position, forming a passage between the feed pipeline 200 and the filling equipment 100. (See Figure 100) Figure 4 In path R04, the system performs the filling operation. For example, both the first switching valve V03 and the second switching valve V04 are in the closed position, and the vapor medium in the second delivery pipeline 320 is isolated at the first switching valve V03 and enters the second discharge pipeline 420, see [link to documentation]. Figure 4 The path R05 in the second delivery pipeline 320 forms a steam barrier on the second side of the first switching valve V03. Thus, based on the first switching valve V03, the steam barrier can further isolate the filling material from the outside world and simultaneously sterilize it, preventing the filling material from being contaminated by the outside world.

[0051] Figure 5 for Figure 1 The diagram shows another workflow of the filling system. (See diagram for example.) Figure 1 and Figure 5 As shown, when the filling equipment 100 is in standby or stopped, both the first isolation valve V01 and the second isolation valve V02 are set to the closed position, isolating the feed line 200 and the filling equipment 100. For example, the first switching valve V03 is in the open position, and the second switching valve V04 is in the closed position. The steam medium in the second conveying line 320 is isolated at the second switching valve V04 after passing through the first switching valve V03 and the second valve chamber V021, and then enters the second discharge line 420. See [reference needed]. Figure 5The steam in the second conveying pipeline 320 can form a steam barrier in the second conveying pipeline 320 and the second valve cavity V021 of the second isolation valve V02, and on the basis of the first isolation valve V01 and the second isolation valve V02, the pre-treatment equipment 001 and the filling equipment 100 are further isolated and sterilized. For example, when the filling equipment 100 is in standby, for example, when the filling equipment 100 is in standby for maintenance, under the protection of the isolation of the second isolation valve and the steam barrier, the pre-treatment equipment 001 can be connected with other equipment to continue production, see Figure 5 The path R07 in the second conveying pipeline 320 ensures production efficiency.

[0052] In some examples, as shown in Figure 1 The first discharge pipeline 410 can include a first discharge branch 411 and a second discharge branch 412. For example, the first discharge branch 411 is used for discharging steam, and the second discharge branch 412 is used for discharging alkali water or acid water. Thus, different media can be discharged through different branches to avoid cross contamination.

[0053] In some examples, as shown in Figure 1 The first conveying pipeline 310 can include a first conveying branch 311 and a second conveying branch 312. For example, the first conveying branch 311 is used for conveying steam, and the second conveying branch 312 is used for discharging alkali water or acid water. Thus, different media can be conveyed through different branches to avoid cross contamination.

[0054] In some examples, as shown in Figure 1 The first conveying branch 311 and the second conveying pipeline 320 can share a steam source.

[0055] Figure 6 Another schematic diagram of a filling system is provided for the embodiments of the utility model. As shown in Figure 6 The filling system further includes a third conveying pipeline 330. The third conveying pipeline 330 is connected with the first discharge pipeline 410, and the connection position P02 of the third conveying pipeline 330 and the first discharge pipeline 410 is located on the side of the second switch valve V04 away from the second isolation valve V02. For example, the second switch valve V04 includes a first side and a second side in the conveying path direction of the first discharge pipeline 410, the second isolation valve V02 is connected with the first switch valve V04 on the first side of the second switch valve V04, and the third conveying pipeline 330 is connected with the first discharge pipeline 410 on the second side of the second switch valve V04.

[0056] As shown in Figure 6As shown, the valve assembly is configured such that when both the first isolation valve V01 and the second isolation valve V02 are in the open position, and both the first switching valve V03 and the second switching valve V04 are in the closed position, the medium in the third delivery pipeline 330 is isolated at the second switching valve V04 and enters the first discharge pipeline 410.

[0057] For example, the medium in the third conveying pipeline 330 can be steam, thereby forming a steam barrier on the second side of the second switching valve V04. In this example, when the first isolation valve V01 and the second isolation valve V02 are in the open position, the raw material in the feed pipeline 200 enters the filling equipment 100 through the first valve chamber V011 and the second valve chamber V021. This steam barrier can further isolate the filling raw material from the outside environment and simultaneously sterilize it, based on the second switching valve V04, preventing the filling raw material from being contaminated by the outside environment.

[0058] In some examples, such as Figure 6 As shown, the valve assembly also includes a second discharge valve V06 disposed on the first discharge pipe 410. The second discharge valve V06 is configured such that: when the second discharge valve V06 is in the closed position, the medium isolated by the second switching valve V04 and entering the first discharge pipe 410 is maintained within the first discharge pipe 410; when the second discharge valve V06 is in the open position, the medium isolated by the second switching valve V04 and entering the first discharge pipe 410 is discharged through the second discharge valve V06. The second discharge valve V06 ensures that the steam barrier is at a high temperature, thereby maintaining the isolation and sterilization functions. For example, when the temperature of the steam in the first discharge pipe 410 is lower than the set temperature, the second discharge valve V06 can be opened, allowing condensate formed by steam cooling in the first discharge pipe 410 to flow and be discharged through the first discharge pipe 410, allowing new high-temperature steam to flow into the first discharge pipe 410; when the temperature of the steam in the first discharge pipe 410 reaches or exceeds the set temperature, the second discharge valve V06 can be closed. For example, the set temperature could be 120 degrees Celsius. For example, if the second discharge valve V06 remains closed for longer than a set time, it can be opened and then closed again after a certain period. For example, this set time could be 1 hour. It should be noted that when the second discharge valve V06 is in both the closed and open positions, steam remains within the first discharge pipe 410 to form a steam barrier.

[0059] In some examples, such as Figure 6As shown, the filling system also includes a second sensor S02, which is installed on the first discharge pipe 410 to measure the temperature of the medium inside the first discharge pipe 410. This allows for control of the opening and closing of the first discharge valve V05, better enabling the steam barrier to perform its isolation and sterilization functions.

[0060] In some examples, such as Figure 6 As shown, when the first discharge pipeline 410 includes a first discharge branch 411 and a second discharge branch 412, the second discharge valve V06 can be located on the first discharge branch 411 or at the beginning of the first discharge branch 411. For example, a third discharge valve V07 is provided on the second discharge branch 412, and the third discharge valve V07 can enable the set medium to be discharged through the second discharge branch 412.

[0061] Figure 7 for Figure 6 The diagram shows a workflow illustration of a filling system. Figure 6 and Figure 7 As shown, both the first isolation valve V01 and the second isolation valve V02 are in the open position, forming a passage between the feed pipeline 200 and the filling equipment 100, allowing the system to perform filling operations. To clearly show the other paths, Figure 7 The path between the feed pipe 200 and the filling equipment 100 is not shown; please refer to [reference needed]. Figure 4 The path R04 in the text.

[0062] For example, such as Figure 6 and Figure 7 As shown, both the first switching valve V03 and the second switching valve V04 are in the closed position, and the steam medium in the second delivery pipeline 320 is isolated at the first switching valve V03 and enters the second discharge pipeline 420. (See Figure 420) Figure 7 The path R05 in the second delivery pipeline 320 forms a steam barrier on the second side of the first switching valve V03. This steam barrier, based on the first switching valve V03, further isolates the filling material from the outside environment and simultaneously sterilizes it, preventing contamination of the filling material. Furthermore, the steam medium in the third delivery pipeline 330 is isolated at the second switching valve V04 and enters the first discharge pipeline 410. See [reference needed]. Figure 7 The path R08 in the second delivery pipeline 320 forms a steam barrier on the second side of the second switching valve V04. Thus, based on the second switching valve V04, the steam barrier can further isolate the filling material from the outside world and simultaneously sterilize it, preventing the filling material from being contaminated by the outside world.
