Description

Technical Field

[0001] The utility model belongs to the field of liquid filling, and specifically relates to a liquid aseptic filling pipeline and a filling machine. Background Art

[0002] Liquid filling occupies an important position in the production process. When the liquid is not enough to use large-scale mechanical filling equipment, people need to use small aseptic tank devices in a sterile environment for filling. Among them, microorganisms are the main source of pollution that affects its quality. The traditional filling chamber is a one-way loop, lacks a sewage channel, and has no separate sewage outlet. It is easy to contact with the external environment during the cleaning and emptying of the pipeline, making it difficult to achieve a sterile state, and it cannot meet the needs of continuous filling of different products. During the filling process, it is often necessary to continuously fill multiple products, and multiple cleaning and sterilization are required, which makes the sewage pressure of the traditional filling pipeline high, which is easy to cause pollution of the operating table. At the same time, it is easy to carry bacteria into the product through the liquid, which does not meet the national food testing standards. It will also shorten the storage period of the liquid and accelerate the deterioration of the liquid. Traditional filling pipelines usually use welding connections. Since the liquid contains solids such as particles, the roughness of the inner wall of the pipeline will affect the flow of the fluid, thereby generating flow resistance and reducing the corrosion resistance of stainless steel.

[0003] Therefore, it is urgent to develop a liquid aseptic filling pipeline and filling machine that is easy to use, can effectively clean and sterilize the filling pipeline, reduce the risk of bacterial infection of the product, and can meet the production of different filling liquids. Utility Model Content

[0004] In order to solve the above technical problems, improve the shortcomings of the existing filling device, and improve the liquid filling efficiency, the utility model is achieved through the following scheme:

[0005] In a first aspect, the utility model provides a liquid aseptic filling pipeline, characterized in that the liquid aseptic filling pipeline comprises a main pipeline, an auxiliary pipeline, a feed pipeline, a three-way ball valve, a return pipeline, a three-way valve and a pipeline connector;

[0006] The feed end of the three-way ball valve is connected to the feed pipeline, and the two discharge ends of the three-way ball valve are connected to the feed ends of the main pipeline and the auxiliary pipeline respectively through pipeline connectors;

[0007] The discharge end of the three-way valve is connected to the feed end of the return pipeline, and a back pressure valve is provided at the discharge end of the return pipeline; the two feed ends of the three-way valve are respectively connected to the discharge ends of the main pipeline and the auxiliary pipeline through pipeline connectors;

[0008] A filling head is arranged on the main pipeline, and a straight ball valve is arranged on the main pipeline between the filling head and the return pipeline; a straight ball valve is also arranged on the auxiliary pipeline.

[0009] Furthermore, the feed pipeline is connected to a three-way ball valve, which can not only change the flow direction between pipelines, but also maintain good sealing to prevent liquid leakage.

[0010] Preferably, the three-way ball valve can be a T-type three-way ball valve, which can flexibly realize the functions of flow distribution, flow direction switching, and fluid mixing, and is easy to install and operate.

[0011] Furthermore, a back pressure valve is provided at the end of the return pipeline to pressurize the sterilizing water in the pipeline so that the water can reach the sterilization temperature (>120°C).

[0012] Furthermore, the straight-through ball valve can effectively maintain the pressure balance in the pipeline and keep a good sealing effect. When the quick-release chuck is removed, it can ensure that the liquid in the pipeline does not drip onto the operating table, so as to avoid contamination of the operating table.

[0013] Furthermore, the auxiliary pipeline is the main sewage pipeline, and can also control the liquid reflux when abnormal filling occurs.

[0014] Furthermore, the main pipeline includes a transverse pipe connecting pipeline, a longitudinal pipe connecting pipeline and an elbow connector.

[0015] Furthermore, the auxiliary pipeline includes a transverse pipe connecting pipeline, a longitudinal pipe connecting pipeline and an elbow connector.

[0016] Furthermore, a five-way ferrule joint is also provided on the main pipeline.

[0017] Furthermore, the five-way ferrule connector is connected to a thermometer, a flow meter and an online solids detector.

[0018] The thermometer can be used to monitor the temperature of the liquid flowing through the pipeline in real time during the filling process to ensure that it remains within the predetermined temperature range to avoid the impact of temperature fluctuations on the effectiveness or physical state of the active substances in the liquid product. At the same time, it can accurately detect the temperature of the sterilizing water to ensure that the entire cleaning and sterilization system and filling pipeline equipment can meet the sterilization temperature to ensure the sterilization effect.

[0019] The flow meter can accurately measure the volume or mass flow of the fluid flowing through the pipeline during the filling process, so as to accurately calculate the product sterilization time and the filling volume.

[0020] The solid online detector can effectively prevent the liquid from being accidentally diluted. It can accurately measure the liquid concentration during the water topping process at the front end of sterilization filling and the water topping process at the end of sterilization filling, ensuring the accurate concentration of the filled product while also reducing product waste.

[0021] Furthermore, the pipe connector includes a straight pipe joint body, a ferrule and a nut.

[0022] Preferably, the design of a ferrule, a straight pipe joint body and a nut is adopted, which not only has a simple structure, no dead angles, and is easy to disassemble and assemble, but also avoids damage to the threads and the inner wall of the pipe by welding, and reduces the corrosion resistance of stainless steel.

[0023] Furthermore, the ferrule is located on the three-way ball valve, straight-through ball valve, back pressure valve and three-way valve; a connecting groove matching with the ferrule is provided on the straight pipe joint body, the nut is sleeved on the ferrule, and the outer wall of the connecting groove is provided with a thread corresponding to the nut.

[0024] Preferably, the ferrule, the straight pipe joint body and the nut are connected by mechanical bite, which is convenient to operate and effectively prevents external microorganisms and other contaminants from entering the pipeline, thereby achieving a stable and reliable sealing effect.

[0025] The connection method of the straight pipe connector body, ferrule and nut is used in combination with aseptic connection technology to prevent microbial intrusion and cross contamination, ensuring that no microbial contamination is introduced during the connection process and that the fastening effect in the pipeline is not affected by flow resistance.

[0026] Furthermore, a gasket is provided between the ferrule and the bottom of the connecting groove.

[0027] Preferably, the gasket can increase the contact area to prevent the ferrule from directly pressing the inner wall of the pipe, causing damage or abrasion to the pipe.

[0028] At the same time, it can achieve a better sealing effect.

[0029] Furthermore, the elbow connector includes an elbow joint body, a ferrule and a nut; the ferrule is located on the horizontal pipe connecting pipeline and the longitudinal pipe connecting pipeline, the elbow joint body is provided with a connecting groove matching with the ferrule, the nut is sleeved on the ferrule, and the outer wall of the connecting groove is provided with a thread corresponding to the nut.

[0030] The nut is used for fastening the connection between the three-way ball valve, straight-through ball valve, back-pressure valve and three-way valve to the horizontal pipe connection pipeline and the vertical pipe connection pipeline. The diameter of the nut is larger than the fracture diameter of the three-way ball valve, straight-through ball valve, back-pressure valve and three-way valve.

[0031] Furthermore, the filling head is also provided with a quick-release chuck, which is detachably connected to the filling head.

[0032] The quick-release chuck is located below the filling head and is connected by a quick locking mechanism. The size of the quick-release chuck matches the diameter of the main pipeline and the filling head. It can achieve quick connection and disconnection during the filling process to meet filling needs, and can frequently clean, disinfect or replace related accessories.

[0033] Furthermore, the main pipeline, auxiliary pipeline, feed pipeline, three-way ball valve, filling head, return pipeline, straight-through ball valve, back pressure valve, three-way valve, pipeline connector and five-way ferrule joint are made of 316L stainless steel.

[0034] 316L stainless steel has a smooth surface and is easy to clean and disinfect. It also has good corrosion resistance and can effectively resist the erosion of acids, alkalis, salts and other corrosive substances.

[0035] Furthermore, the liquid aseptic filling pipeline is designed as a return-shaped or fan-shaped structure.

[0036] Preferably, a vertical pipeline can be used instead of a horizontal pipeline. By changing the structural layout of the filling pipeline, the floor space of the pipeline can be reduced, thereby improving space utilization.

[0037] In a second aspect, the utility model provides a liquid aseptic filling machine, which also includes a filling host, a cleaning and sterilization system, and an operating table.

[0038] The cleaning and sterilization system, the filling host and the liquid aseptic filling pipeline are connected in sequence, and the return pipeline of the liquid aseptic filling pipeline is connected to the return port of the cleaning and sterilization system; the liquid aseptic filling pipeline is arranged in the operating table.

[0039] Furthermore, the operating table is a sterile sealed operating table; the feed pipeline and the return pipeline pass through the side wall of the operating table in parallel.

[0040] The feed and discharge pipelines are separated and arranged in parallel, which can effectively avoid the problem of material backflow or cross contamination, making the entire liquid aseptic filling pipeline layout more compact and orderly.

[0041] Furthermore, the liquid aseptic filling pipeline is arranged on the operating table through a support frame.

[0042] The utility model provides a liquid aseptic filling machine, which includes a liquid aseptic filling pipeline, a filling host, a cleaning and sterilization system, and an operating table. The main pipeline and the auxiliary pipeline are designed in parallel, and a special structure pipeline connector is used between the pipeline and the control valve. It not only meets the requirements of liquid filling and cleaning and sterilization, but also effectively maintains a closed environment during the filling process, ensures consistency between filling batches, reduces the risk of external contamination, and avoids the occurrence of cross infection.

[0044] 1. The liquid aseptic filling pipeline of the liquid aseptic filling machine of the utility model is respectively provided with a main pipeline and an auxiliary pipeline. The two pipelines are designed in parallel, which not only meets the requirements of liquid filling, cleaning and sterilization, but also can meet the needs of continuous filling of different products; at the same time, it can effectively avoid contact contamination between the pipeline and the outside world, and can also prevent cross contamination of filling different products, thereby ensuring the consistency between filling batches and avoiding contamination of products and operating tables.

[0062] The auxiliary pipeline is connected in parallel with the main pipeline, the feed pipeline 1 is connected to the feed end of the three-way ball valve 2, the discharge end of the three-way ball valve 2 is connected to the cross-pipe connecting pipe 11 through a pipeline connector, the cross-pipe connecting pipeline 11 is connected to one end of the elbow connector 13, the other end of the elbow connector 13 is connected to the longitudinal pipe connecting pipeline 12, the longitudinal pipe connecting pipeline 12 is connected to one end of the elbow connector 13, the other end of the elbow connector 13 is connected to the cross-pipe connecting pipeline 11, a straight-through ball valve B7 is provided on the cross-pipe connecting pipeline 11, the straight-through ball valve B7 is connected to the feed end of the three-way valve 8 through the cross-pipe connecting pipeline 11, the discharge end of the three-way valve 8 is connected to the return pipeline 9, and a back pressure valve 10 is provided on the return pipeline.

[0063] 1) Cleaning process (such as Figure 3 (shown)

[0064] Start-up cleaning: Cleaning is for the entire pipeline. First, flush the pipeline with pure water until it is clean, and then carry out CIP process cleaning, which is a five-step cleaning method of water, alkali, water, acid, and water.

[0065] After cleaning: the cleaning agent (acid and alkali) is recovered through the return pipeline, and the sterilizer and aseptic filling machine are gradually turned off. After the last pure water cleaning, it is not emptied. (At this time, the liquid aseptic filling pipeline is in a fully connected state)

[0066] 2) Pipeline sterilization process (such as Figure 3 (shown)

[0067] Start sterilization: Before sterilizing and filling the product, all pipelines of the UHT sterilizer and liquid aseptic filling pipeline must be sterilized first. During the sterilization process, the pure water is heated by the UHT sterilizer and pressurized through the back pressure valve at the end of the return pipeline to raise the water temperature in the entire pipeline to 120°C and maintain it for 20 minutes to achieve the sterilization purpose.

[0068] 3) Filling process (such as Figure 4 (shown)

[0069] Filling start: Before starting filling, adjust the three-way ball valve 2 to a state where only the auxiliary pipeline is connected, adjust the straight ball valve A6 on the main pipeline to a closed state, and then remove the quick-release chuck 5 connected to the filling head 4. The UHT sterilizer is fed through the feed pipeline, and the sterilizing water in all pipelines is discharged through the return pipeline. After a period of time, adjust the straight ball valve B7 to a closed state, and adjust the three-way ball valve 2 to a state where only the discharge end of the main pipeline is connected, and prepare for filling.

[0070] Filling pipeline: The liquid product flows through the feed pipeline 1 through the feed end of the three-way ball valve 2, flows out from the opening direction of the three-way ball valve according to the connection direction of the three-way ball valve 2, along the horizontal connection line 11, the five-way ferrule joint 3, the horizontal pipe connection pipeline 11, the elbow connector 13, and the longitudinal connection pipeline 12, and reaches the filling head 4. Confirm that the quick-release chuck 5 is in the disconnected state and the straight-through ball valve A6 is in the closed state. (The thermometer 14, flowmeter 15 and solid online detector 16 are installed on the five-way ferrule joint).

[0071] Liquid pre-flow: Since there may be water left in the sterilization process in the main pipeline, in order to prevent the quality of the filled product, the concentration of the liquid is detected when the liquid product passes through the solid online detector 16. When the liquid concentration is lower than the standard value, the liquid in the pipeline is pre-flowed and collected through the filling head. When the liquid concentration reaches the standard value, open the straight ball valve B7, switch the three-way ball valve to connect only to the auxiliary pipeline, place the filling container under the filling head, switch the three-way ball valve to connect only to the main pipeline again, close the straight ball valve B7, and start filling.

[0072] Filling control: During the filling process, the liquid flow rate is observed through the flow meter 15. When the liquid flow rate is abnormal, the filling speed is adjusted by changing the sterilizer material pump frequency.

[0073] End of filling: After filling is completed, adjust the three-way ball valve 2 to the direction connected only to the auxiliary pipeline, the straight-through ball valve B7 is in the open state, connect the quick-release chuck, adjust the three-way ball valve to the three-way open state, open the straight-through ball valve A6, and prepare for the next cleaning operation.
