Description

Technical Field

[0001] This invention relates to the field of aseptic filling production equipment technology. Background Technology

[0002] The structure of traditional aseptic filling equipment mainly includes: an ultra-high temperature sterilizer (UHT), an aseptic tank, a filling machine, and a shielded steam pipeline system. The UHT sterilizer is equipped with a sterilizer output pipe and a sterilizer return pipe. The aseptic tank has a material pipe at the bottom. The filling machine has a filling machine inlet pipe. The sterilizer output pipe, sterilizer return pipe, aseptic tank material pipe, and filling machine inlet pipe are all connected to an aseptic anti-mixing valve assembly. The sterilizer output pipe can be connected to the sterilizer return pipe, the aseptic tank material pipe, and the filling machine inlet pipe simultaneously through the aseptic anti-mixing valve assembly. The aseptic tank material pipe can be connected to the filling machine inlet pipe through the aseptic anti-mixing valve assembly.

[0003] Companies typically use a single aseptic filling system to produce multiple products. When changing products, to prevent cross-contamination of flavors, the entire aseptic filling system needs to undergo in-situ pipeline cleaning (CIP cleaning). Once CIP cleaning is performed, the system's aseptic state is compromised, necessitating steam pipeline sterilization (SIP sterilization) to rebuild aseptic conditions. A single SIP sterilization process takes approximately two hours, causing production downtime and impacting efficiency. Summary of the Invention

[0008] Furthermore, in the aforementioned aseptic filling device capable of quick product replacement, a cleaning ball is provided inside the aseptic tank, and the aseptic tank cleaning input pipe is connected to the cleaning ball.

[0009] Furthermore, in the aforementioned aseptic filling device capable of quick product replacement, an in-situ cleaning control valve is also provided on the aseptic tank cleaning input pipe. The in-situ cleaning control valve is connected to the in-situ cleaning input pipe. A one-way valve and an in-situ cleaning input control valve are sequentially provided at the input end of the in-situ cleaning input pipe along the flow direction of the detergent liquid. A fifth shielded steam input pipe with a control valve is connected to the in-situ cleaning input pipe between the in-situ cleaning input control valve and the in-situ cleaning control valve.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, an aseptic filling device capable of quick product changeover includes: an ultra-high temperature sterilizer 1, an aseptic tank 2, a filling machine 3, and a shielded steam inlet pipe 4. The ultra-high temperature sterilizer 1 is equipped with a sterilizer output pipe 11 and a sterilizer return pipe 12. The aseptic tank 2 is connected to a sterile gas inlet pipe 24, and the bottom of the aseptic tank 2 is connected to a sterile tank material pipe 21. The filling machine 3 is equipped with a filling machine inlet pipe 31 and a filling machine output pipe 32.

[0022] In this embodiment, a first T-valve 121 is provided on the sterilizer return pipe 12, and a quick-change cleaning pipe 5 is connected to the first T-valve 121. The quick-change cleaning pipe 5 is connected to the aseptic tank quick-cleaning control valve 501. The aseptic tank quick-cleaning control valve 501 is provided on the aseptic tank cleaning input pipe 22 of the aseptic tank 2. In order to facilitate the cleaning of the aseptic tank 2, a cleaning ball 201 is provided inside the aseptic tank 2. The output end of the aseptic tank cleaning input pipe 22 is connected to the cleaning ball 201.

[0023] A first shielded steam line 6 is connected to one end of the quick-change cleaning line 5 near the sterile tank cleaning input line 22. The input end of the first shielded steam line 6 is equipped with a first shielded steam line input control valve 61, and the output end of the first shielded steam line 6 is equipped with a first shielded steam line output control valve 62. A first connecting pipe 51 is connected to one end of the quick-change cleaning line 5 near the first T-valve 121. A first connecting pipe control valve 511 and a first steam trap 512 are installed on the first connecting pipe 51. The first steam trap 512 is used to discharge condensate steam. A second shielded steam line 7 is connected to the first connecting pipe 51 between the first connecting pipe control valve 511 and the first steam trap 512. A second shielded steam line input control valve 71 is installed at the input end of the second shielded steam line 7, and the output end of the second shielded steam line 7 is equipped with a second shielded steam line output control valve 72.

[0024] The sterilizer output pipe 11, sterilizer return pipe 12, aseptic tank material pipe 21, and filling machine feed pipe 31 are all connected to the aseptic anti-mixing valve group 10. The aseptic anti-mixing valve group 10 includes: a first aseptic control valve 101 and a second aseptic control valve 102. A valve chamber 103 for connection or shielding is provided between the first aseptic control valve 101 and the second aseptic control valve 102. The sterilizer output pipe 11 is connected to the sterilizer return pipe 12 through the first aseptic control valve 101. The aseptic tank material pipe 21 and the filling machine feed pipe 31 are both connected to the second aseptic control valve 102. The two ends of the valve chamber 103 are respectively connected to a first steam shielding valve 104 and a second steam shielding valve 105. The first steam shielding valve 104 and the second steam shielding valve 105 are respectively connected to the third shielded steam pipeline 8. The third shielded steam pipeline 8 has an input control valve 801 at its input end, a switching control valve 802 on its output end between the first steam shielding valve 104 and the second steam shielding valve 105, and an output control valve 803. A third shielded steam condensate discharge pipe 81 with a second steam trap 811 is also provided at the output end of the third shielded steam pipeline 8. The second steam trap 811 is used to discharge condensate steam.

[0025] The input ends of the first shielded steam pipeline 6, the second shielded steam pipeline 7, and the third shielded steam pipeline 8 are all connected to the shielded steam inlet pipe 4.

[0026] In this embodiment, an in-situ cleaning control valve 23 is also provided on the aseptic tank cleaning input pipe 22. The in-situ cleaning control valve 23 is connected to the in-situ cleaning input pipe 24. A one-way valve 241 and an in-situ cleaning input control valve 242 are sequentially arranged at the input end of the in-situ cleaning input pipe 24 along the flow direction of the detergent liquid. A fifth shielded steam input pipe 25 with a control valve is connected to the in-situ cleaning input pipe 24 between the in-situ cleaning input control valve 242 and the in-situ cleaning control valve 23. The fifth shielded steam input pipe 25 is connected to the shielded steam inlet pipe 4. The in-situ cleaning input pipe 24 facilitates in-situ cleaning of the aseptic tank when necessary. When in-situ cleaning (CIP cleaning) is not performed, the shielded steam in the shielded steam inlet pipe 4 enters the in-situ cleaning input pipe 24 through the fifth shielded steam input pipe 25, filling the in-situ cleaning input pipe 24 between the in-situ cleaning input control valve 242 and the in-situ cleaning control valve 23 with shielded steam, ensuring that the in-situ cleaning input pipe 24 always remains sterile.

[0027] In this embodiment, a filling machine output control valve 321 is provided on the filling machine output pipe 32. The filling machine output control valve 321 is connected to the output end of the fourth shielded steam pipeline 9. The input end and output end of the fourth shielded steam pipeline 9 are respectively provided with a fourth shielded steam pipeline input control valve 901 and a fourth shielded steam pipeline output control valve 902. The input end of the fourth shielded steam pipeline 9 is connected to the shielded steam inlet pipe 4. A discharge pipe 33 with a third drain valve 331 and a fourth discharge control valve 332 is also connected to the filling machine output control valve 321.

[0028] The working principle is as follows. Figures 1 to 6 Arrows are used to indicate the direction of material or sterile water flow, and thick solid lines are used to indicate the introduction of shielding steam.

[0029] like Figure 1 As shown, the aseptic filling device produces the first product, and the material is being transported from the ultra-high temperature sterilizer 1 to the aseptic tank 2 and the filling machine 3. The specific process is as follows: Material is output from the sterilizer output pipe 11 of the ultra-high temperature sterilizer 1, and a portion of the material flows back into the ultra-high temperature sterilizer 1 via the sterilizer return pipe 12. Another portion of the material passes through the first aseptic control valve 101 and valve chamber 103 of the aseptic anti-mixing valve group 10 to the second aseptic control valve 102. A portion of the material output from the second aseptic control valve 102 enters the aseptic tank 2 via the aseptic tank material pipe 21, and another portion of the material output from the second aseptic control valve 102 enters the filling machine 3 via the filling machine feed pipe 31 for filling. Compressed aseptic gas is input into the aseptic tank 2 through the aseptic gas input pipe 26, thereby maintaining a positive pressure state inside the aseptic tank 2 at all times.

[0030] In this state, the first shielded steam pipeline input control valve 61, the first shielded steam pipeline output control valve 62, and the first connecting pipe control valve 511 on the first shielded steam pipeline 6 are all open. The shielded steam in the shielded steam inlet pipe 4 enters the quick-change cleaning pipeline 5 through the first shielded steam pipeline 6, and then enters the first connecting pipe 51 through the first connecting pipe control valve 511, ensuring that the quick-change cleaning pipeline 5 remains sterile. The second shielded steam pipeline input control valve 71 and the second shielded steam pipeline output control valve 72 on the second shielded steam pipeline 7 are closed. The third shielded steam pipeline input control valve 801 and the third shielded steam pipeline switching control valve 802 are in the open state, while the first steam shielding valve 104 and the second steam shielding valve 105 are in the closed state. Shielded steam enters the third shielded steam pipeline 8 and, via the third shielded steam pipeline switching control valve 802, enters the third shielded steam pipeline end control valve 803. The shielded steam shields the pipeline steam outside the first steam shielding valve 104 and the second steam shielding valve 105 at both ends of the valve chamber 103, ensuring that the valve chamber 103 is not contaminated during production. In addition, the fourth shielded steam pipeline input control valve 901 and the fourth shielded steam pipeline output control valve 902 are in the open state, while the filling machine output control valve 321 is closed. Shielded steam enters the fourth shielded steam pipeline 9 and, via the fourth shielded steam pipeline output control valve 902 and the filling machine output control valve 32, fills the discharge pipe 33 at the fourth discharge control valve 332, thereby ensuring that the filling machine 3 remains sterile.

[0031] like Figure 2 As shown, the aseptic filling device continues to produce the first product. When the first product is almost finished, the ultra-high temperature sterilizer 1 stops feeding material to the aseptic tank 2, and the material in the filling machine 3 is supplied by the aseptic tank 2. The specific process is as follows: The material is output from the sterilizer output pipe 11 of the ultra-high temperature sterilizer 1, and then flows back into the ultra-high temperature sterilizer 1 through the sterilizer return pipe 12. At this time, the ultra-high temperature sterilizer 1 is in a material self-circulation state. The material in the aseptic tank 2 passes through the aseptic tank material pipe 21, the second aseptic control valve 102, and then enters the filling machine 3 through the filling machine feed pipe 31 for filling.

[0032] In this state, the shielding steam in the shielding steam inlet pipe 4 still enters the quick-change cleaning pipe 5 and the first connecting pipe 51 via the first shielding steam pipe 6 to ensure that the quick-change cleaning pipe 5 remains sterile. The second shielding steam pipe input control valve 71 and the second shielding steam pipe output control valve 72 on the second shielding steam pipe 7 remain closed. The third shielding steam pipe switching control valve 802 is closed, and the first steam shielding valve 104 is open. The shielding steam enters the valve chamber 103 via the third shielding steam pipe 8, then through the first steam shielding valve 104, and enters the output end of the third shielding steam pipe 8 via the second steam shielding valve 105. The valve chamber 103 is filled with shielding steam, thereby ensuring that the valve chamber 103 remains sterile. In addition, the shielding steam still fills the discharge pipe 33 at the position of the fourth discharge control valve 332 via the fourth shielding steam pipe 9, the fourth shielding steam pipe output control valve 902, and the filling machine output control valve 321, thereby ensuring that the filling machine 3 continues to remain sterile.

[0033] like Figure 3 As shown, when the aseptic filling device needs to fill a second product, the ultra-high temperature sterilizer 1 first enters a sterile water circulation state. Specifically, sterile water is output from the sterilizer output pipe 11 of the ultra-high temperature sterilizer 1, flows back into the ultra-high temperature sterilizer 1 through the sterilizer return pipe 12, and the ultra-high temperature sterilizer 1 enters a water circulation state, thereby rinsing the interior of the ultra-high temperature sterilizer 1. The aseptic tank 2 and the filling machine 3 are in a stopped state.

[0034] In this state, the shielding steam in the shielding steam inlet pipe 4 still enters the quick-change cleaning pipe 5 and the first connecting pipe 51 via the first shielding steam pipe 6 to ensure that the quick-change cleaning pipe 5 remains sterile. The second shielding steam pipe input control valve 71 and the second shielding steam pipe output control valve 72 on the second shielding steam pipe 7 remain closed. The third shielding steam pipe input control valve 801 is open, the third shielding steam pipe switching control valve 802 remains closed, the first steam shielding valve 104 is open, and shielding steam enters the third shielding steam pipe 8 and then enters the valve chamber 103 through the first steam shielding valve 104, which remains full of shielding steam. The process of the second steam trap 811 discharging condensed steam is also the process of cleaning the valve chamber 103. In addition, shielding steam enters the fourth shielding steam pipe 9 and the discharge pipe 91 to continue to ensure that the filling machine 3 remains sterile.

[0035] like Figure 4As shown, after a period of time, the ultra-high temperature sterilizer 1 prepares sterile water and continues its self-circulation. The sterile tank 2, filling machine 3, and pipelines are prepared for cleaning. The specific process is as follows: Sterile water is output from the sterilizer output pipe 11 of the ultra-high temperature sterilizer 1, and then flows back into the ultra-high temperature sterilizer 1 through the sterilizer return pipe 12. The ultra-high temperature sterilizer 1 is in a sterile water self-circulation state. The sterile tank 2 and filling machine 3 are in a stopped state. At this time, the steam shielding state is... Figure 3 The same applies to the Chinese text, so I will not repeat it here.

[0036] like Figure 5 As shown, at this time, the first connecting pipe control valve 511 and the first shielded steam pipeline output control valve 62 are closed, while the aseptic tank quick cleaning control valve 501 is opened. This allows the sterile compressed gas inside the aseptic tank 2 to enter the quick switching cleaning pipeline 5, maintaining a positive pressure and continuing to ensure sterility within the pipeline. After a period of time, the first T-valve 121 opens, and part of the sterile water output from the sterilizer output pipe 11 of the ultra-high temperature sterilizer 1 flows back to the ultra-high temperature sterilizer 1 via the sterilizer return pipe 12. The other part enters the aseptic tank 2 via the quick switching cleaning pipeline 5, the aseptic tank quick cleaning control valve 501, and the cleaning ball 201, thereby cleaning the inside of the aseptic tank 2. The liquid generated during the internal cleaning of the aseptic tank 2 is discharged outwards via the aseptic tank material pipe 21, the second aseptic control valve 102, the filling machine inlet pipe 31, the filling machine 3, the filling machine outlet pipe 32, the discharge pipe 91, and the fourth discharge control valve 332, thereby achieving rapid cleaning of the aseptic tank 2, the filling machine 3, and related pipelines. During this process, the shielding steam is only used for shielding within the first shielding steam pipeline 6. The second shielding steam pipeline inlet control valve 71 and the second shielding steam pipeline outlet control valve 72 on the second shielding steam pipeline 7 are both open, allowing the shielding steam to enter the second shielding steam pipeline 7 and the first connecting pipe 51. The third shielded steam pipeline input control valve 801 remains open, the third shielded steam pipeline switching control valve 802 remains closed, the first steam shielding valve 104 is open, and shielded steam enters the valve chamber 103 through the third shielded steam pipeline 8, then through the first steam shielding valve 104, and finally through the second steam shielding valve 105 to the output end of the third shielded steam pipeline 8. The valve chamber 103 is filled with shielded steam, thus ensuring that the valve chamber 103 remains sterile. In addition, shielded steam enters the fourth shielded steam pipeline output control valve 902 through the fourth shielded steam pipeline 9, ensuring that the outside of the filling machine output control valve 321 remains sterile.

[0037] like Figure 6As shown, after a period of rapid cleaning, the aseptic tank 2, filling machine 3, and related pipelines are cleaned. At this time, the first T-valve 121 closes, and the sterile water output from the sterilizer output pipe 11 of the ultra-high temperature sterilizer 1 flows back into the ultra-high temperature sterilizer 1 through the sterilizer return pipe 12, and the ultra-high temperature sterilizer 1 continues its sterile water self-circulation state. The first shielded steam pipeline output control valve 62 opens, the first connecting pipe control valve 511 opens, and the aseptic tank rapid cleaning control valve 501 closes. The shielded steam re-enters the rapid switching cleaning pipeline 5 through the first shielded steam pipeline 6. The second shielded steam pipeline input control valve 71 and the second shielded steam pipeline output control valve 72 on the second shielded steam pipeline 7 are closed again. The aseptic filling device returns to the standby state for the production of the second product and is about to begin production of the second product.

[0038] The above process describes how to switch between two products through rapid cleaning. Sterile water prepared by an ultra-high temperature sterilizer is used to quickly switch the cleaning pipeline to flush the sterile tank and related pipelines. Throughout the rapid cleaning and switching process, the sterile tank 2 and related pipelines remain sterile. Therefore, there is no need to rebuild the sterile state after rapid cleaning, which can truly achieve rapid switching to the second product. This greatly saves on product filling production costs and improves production efficiency.
