Description

Technical Field

[0001] This utility model relates to an aseptic tank structure for a continuous bag filling machine. Background Technology

[0002] Aseptic bag packaging technology is widely used in the packaging of liquid foods. It utilizes aseptic bags made from a high-tech new packaging material based on polyethylene granules, typically with capacities of 5L, 10L, and 20L. These aseptic bags are available in individual bags and continuous bags. Individual bags are suitable for manual filling machines, requiring manual assistance to align the bag opening with the filling nozzle for each bag. Continuous bags refer to a certain number of aseptic bags manufactured with point-seam breaks, which are then separated after filling. In the domestic market, manual filling of individual bags is the primary method.

[0003] Because the filling machine fills materials intermittently, while the front-end sterilizer supplies materials continuously, when the filling machine stops, there is no sterile tank for intermediate buffering, and the material needs to return to the beginning for secondary sterilization, resulting in material waste. Furthermore, as an aseptic filling machine, it needs to perform CIP (clean-in-place) and SIP (sterilization-in-place), but the sterile chamber is small and the piping connection is complicated, resulting in dense piping, reduced operating and maintenance space, and safety hazards due to high-temperature piping.

[0004] Therefore, an aseptic tank structure for a continuous bag filling machine is proposed to address the above issues. Utility Model Content

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-9 An aseptic tank structure for a continuous bag filling machine includes a piping unit 1 and an aseptic tank unit 2. The piping unit 1 includes a steam piping assembly 101, a cooling water piping assembly 102, a compressed air piping assembly 103, and a frame 104. The steam piping assembly 101, cooling water piping assembly 102, and compressed air piping assembly 103 are all mounted on the frame 104. One end of the steam piping assembly 101 is connected to a steam source, and the other end is connected to the aseptic tank unit 2. One end of the cooling water piping assembly 102 is connected to a cooling water source, and the other end is connected to the aseptic tank unit 2. One end of the compressed air piping assembly 103 is connected to a compressed air source, and the other end is connected to the aseptic tank unit 2. The steam piping assembly 101, cooling water piping assembly 102, and compressed air piping assembly 103 are respectively connected to the frame 104 via multiple pipe supports.

[0038] Specifically, piping unit 1 and aseptic tank unit 2 are two relatively independent units that are interconnected to achieve the interaction of water, gas, and steam to accomplish the required functions. Steam piping assembly 101, cooling water piping assembly 102, and compressed air piping assembly 103 are three independent pipelines, each of which is fixed to frame 104 by a pipe bracket.

[0039] Please see Figure 1 , 3 The steam piping assembly 101 includes a steam inlet 1011, multiple pressure gauges 1012, a steam pressure reducing valve 1013, a switching valve group 1014, a steam trap 1015, a CIP inlet 1016, and a steam / CIP interface 1017. One end of the steam inlet 1011 is connected to a steam source, and the other end is connected to a pressure gauge 1012. The other end of the pressure gauge 1012 is connected to the steam pressure reducing valve 1013. The other end of the steam pressure reducing valve 1013 is connected to two pressure gauges 1012. The other end of the pressure gauge 1012 is connected to the switching valve group 1014. The switching valve group 1014 is connected to the steam trap 1015, the CIP inlet 1016, and the steam / CIP interface 1017, respectively. The steam / CIP interface 1017 is connected to the aseptic tank unit 2.

[0040] Specifically, external steam enters through steam inlet 1011. The steam pressure is reduced by steam pressure reducing valve 1013, and the effectiveness of steam pressure reducing valve 1013 is monitored by comparing the pressure gauges 1012 before and after it. Simultaneously, shut-off and filtering components are installed before and after steam pressure reducing valve 1013. The treated steam is switched via switching valve assembly 1014 and enters aseptic tank unit 2 through steam / CIP inlet 1017. Condensate in the pipeline is discharged through steam trap 1015 to reduce secondary steam loss. External CIP cleaning fluid enters the filling machine through CIP inlet 1016. After switching via the aseptic valve in switching valve assembly 1014, the CIP cleaning fluid also enters aseptic tank unit 2 through steam / CIP inlet 1017.

[0041] Specifically, the steam pipeline assembly 101 integrates functions such as shut-off, pressure reduction, and filtration. The pressure gauges 1012 installed before and after the steam pressure reducing valve 1013 ensure that the steam pressure entering the sterile tank is maintained within a suitable range.

[0042] Specifically, the external CIP cleaning fluid is connected to the switching valve assembly 1014. By switching the sterile valve, the steam entering the sterile tank can be switched to CIP cleaning fluid. Entering from the spray ball at the top of the sterile tank, CIP cleaning of the sterile tank and the entire production pipeline can be completed. The switching valve assembly 1014 is connected to an external steam trap to discharge condensate and reduce the loss of secondary steam.

[0043] Please see Figure 1 , 4 The cooling water piping assembly 102 includes a cooling water inlet 1021, an inlet butterfly valve 1022, an outlet butterfly valve 1023, and a cooling water outlet 1024. The upper end of the cooling water inlet 1021 is connected to the sterile tank unit 2, and the lower end is connected to the inlet butterfly valve 1022. The inlet butterfly valve 1022 is connected to the cooling water source and the outlet butterfly valve 1023 respectively. The other end of the outlet butterfly valve 1023 is connected to the cooling water outlet 1024.

[0044] Specifically, external cooling water is supplied through the cooling water inlet 1021. When the aseptic tank 201 requires cooling after SIP (Self-Installation Processing), the inlet butterfly valve 1022 opens and the outlet butterfly valve 1023 closes, allowing cooling water to enter the jacket of the aseptic tank 201 through the lower cooling water inlet 2016 to cool the tank. Overflow cooling water is discharged through the upper cooling water inlet 2017. After the aseptic tank 201 has finished cooling, the inlet butterfly valve 1022 closes and the outlet butterfly valve 1023 opens, allowing excess cooling water in the jacket of the aseptic tank 201 to flow out through the lower cooling water inlet 2016 and be discharged through the cooling water outlet 1024.

[0045] Specifically, external cooling water is connected to the cooling water piping assembly 102, entering the outer jacket from the bottom interface of the aseptic tank 201 and flowing out from the top interface, completing the circulation. Its main function is to rapidly cool the aseptic tank after SIP (Self-Installation Processing), shortening production time. After cooling is complete, excess cooling water is discharged from the bottom interface.

[0046] Specifically, the entry and exit of cooling water are accurately controlled by the interaction of opening and closing of two pneumatic butterfly valves (inlet butterfly valve 1022 and outlet butterfly valve 1023).

[0047] Please see Figure 1 , 5 The compressed air pipeline assembly 103 includes a compressed air inlet 1031, an air filter assembly 1032, an air pressure reducing valve 1033, a safety valve 1034, and a sterile air inlet 1035. One end of the compressed air inlet 1031 is connected to a compressed air source, and the other end is connected to the air filter assembly 1032. The other end of the air filter assembly 1032 is connected to the air pressure reducing valve 1033. The other end of the air pressure reducing valve 1033 is connected to the safety valve 1034. The other end of the safety valve 1034 is connected to the sterile air inlet 1035. The sterile air inlet 1035 is connected to the sterile tank unit 2.

[0048] Specifically, external compressed air is supplied through compressed air inlet 1031, and the supply is controlled by a manual ball valve. After being processed by air filter assembly 1032, the compressed air becomes sterile air suitable for material contact. The pressure inside the sterile tank is then regulated by air pressure reducing valve 1033, which includes a built-in pointer pressure gauge. The processed compressed air is then supplied to sterile tank unit 2 through sterile air inlet 1035. A safety valve 1034 is installed in the pipeline. During SIP and production processes, if the pressure inside sterile tank 201 exceeds its design pressure resistance, steam and sterile air will flow in reverse through sterile air inlet 1035 and release pressure through safety valve 1034 to protect sterile tank 201.

[0049] Specifically, external compressed air is connected to the compressed air pipeline assembly 103, and after filtration and pressure regulation, it is directly introduced into the aseptic tank 201 to come into contact with the material. During the filling process, filling can be carried out by pressurizing the air, reducing the filling time per bag and increasing production speed. The reduction in filling time per bag is more significant in the production of large-capacity bags.

[0050] Specifically, the external connecting pipe is equipped with a safety valve 1034 to ensure that the pressure inside the aseptic tank can be released in time when it is too high, thus protecting the aseptic tank.

[0051] Please see Figure 1 , 6 7, 8, The aseptic tank unit 2 includes an aseptic tank 201 and an aseptic valve assembly 202. The aseptic tank 201 is provided with an aseptic air inlet 2011 at its upper end, which is connected to an aseptic air interface 1035. The aseptic tank 201 is provided with a cooling water submersible interface 2016 at its lower end, which is connected to a cooling water inlet interface 1021. The aseptic tank 201 is provided with a cooling water upper interface 2017 at the upper end of its side wall. The aseptic tank 201 is provided with a manhole 2013 and a first material inlet 2014 at its upper end. The manhole 2013 is provided with a first steam / CIP inlet 2012. The aseptic valve assembly 202 is connected to the first steam / CIP inlet 2012 and the first material inlet 2014 respectively. The aseptic tank 201 is provided with a first material outlet 2018 at its lower end.

[0052] Please see Figure 9 The second steam / CIP inlet 2021 on the aseptic valve assembly 202 is connected to the steam / CIP interface 1017; the aseptic valve assembly 202 is connected to the first steam / CIP inlet 2012 and the first material inlet 2014 respectively; the aseptic valve assembly 202 is also provided with a second material inlet 2022 and a second material outlet 2023.

[0053] Specifically, the outer wall of the aseptic tank 201 is equipped with an installation bracket 2015.

[0054] Specifically, the installation of the aseptic tank 201 and the aseptic valve assembly 202 involves both direct welding through pipes and chuck connections, primarily for the maintenance of the aseptic tank 201. Treated sterile air is directly introduced into the aseptic tank 201 through the sterile air inlet 2011. The first steam / CIP inlet 2012 is installed on the cover of the manhole 2013, with a spray ball installed inside the cover for better cleaning and sterilization. The material inlet 2014 is the welded interface for the aseptic valve assembly 202. According to the installation requirements of the aseptic tank 201, a bracket 2015 needs to be welded to the outside. Material transport in the aseptic tank 201 is achieved through the material outlet 2018 connected to the rear end.

[0055] Specifically, the second material inlet 2022 connects to the material coming from the sterilizer, and the second material outlet 2023 connects to the material returning to the sterilizer. The liquid level of the material in the sterile tank is controlled by the aseptic valve assembly 202.

[0056] The aseptic tank structure of this continuous bag filling machine temporarily stores production materials. The aseptic tank is connected to the filling nozzle, with a controllable diaphragm valve and flow meter installed in the connecting pipe for precise control. The aseptic tank has high and low level monitoring to monitor the material level and allow for timely replenishment to meet the filling requirements of aseptic bags of different capacities. Piping unit 1 and aseptic tank unit 2 are relatively independent, connected by aseptic piping, resulting in a compact and simple structure. This design improves the production speed of the continuous bag filling machine while making its operation more stable. External interfaces are completely centralized in the auxiliary unit and located away from the operating side, enhancing safety.
