BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a structural schematic diagram of the aseptic carbonated beverage preparation device of the present invention. DETAILED DESCRIPTION

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

[0021] like Figure 1As shown, the aseptic carbonated beverage preparation device includes: a sugar water mixing device 1, an ultra-high temperature instantaneous sterilizer 2, and an aseptic storage tank 3. In order to ensure the cleanliness of the aseptic storage tank 3, the roughness of the inner wall of the aseptic storage tank 3 is Ra ≤ 0.4µm.

[0022] The sugar water mixing device 1 includes a syrup tank 11 and a degassing tank 12 capable of removing air from process water. The degassing tank output pipe 121 on the degassing tank 12 and the syrup tank output pipe 111 on the syrup tank 11 are both connected to the mixing pipeline 4.

[0023] The degassing tank output pipe 121 is equipped with a water delivery centrifugal pump 122, a water delivery flowmeter 123, and a water delivery check valve 124, arranged in the direction of water delivery. The water delivery check valve 124 effectively prevents liquid outside the degassing tank output pipe 121 from flowing into the degassing tank output pipe 121. The degassing tank 12 is equipped with a water inlet pipe 126 with a water inlet control valve 125. The degassing tank 12 is also equipped with a vacuum line 127, which is equipped with a vacuum pump 128 and a degassing tank pressure sensor 129. The vacuum line 127 is also equipped with a pressure regulating pipe 130, which is equipped with a pressure regulating manual ball valve 131.

[0024] RO water is replenished into the degassing tank 12 through the water inlet pipe 126. RO water is water filtered through a reverse osmosis membrane. A vacuum pump 128 evacuates the degassing tank 12, maintaining a negative pressure. This negative pressure removes air from the RO water. A degassing tank pressure sensor 129 monitors the pressure in the degassing tank 12 in real time, and the vacuum level can be adjusted using a pressure-regulating manual ball valve 131. The deaerated water in the degassing tank 12 is pumped out through the degassing tank output pipe 121 by the water delivery centrifugal pump 122. A water delivery flowmeter 123 monitors the water flow in real time.

[0025] Syrup delivery pipe 111 is provided with a syrup delivery pump 112, a syrup flowmeter 113, and a syrup ratio control valve 114, arranged in sequence along the syrup delivery direction. Syrup tank 11 is provided with a syrup inlet pipe 115, which is also equipped with a syrup inlet control valve 116. Syrup is replenished into syrup tank 11 through syrup inlet pipe 115.

[0026] The mixing line 4 is connected to the input of the ultra-high temperature instantaneous sterilizer 2, and the output of the ultra-high temperature instantaneous sterilizer 2 is connected to the sterile buffer tank 5. To ensure the cleanliness of the sterile buffer tank 5, the roughness of the inner wall of the sterile buffer tank 5 is Ra ≤ 0.4µm. The sterile buffer tank 5 is connected to a buffer output pipe 51 equipped with a first sterile centrifugal pump 511 and a liquid flow meter 512. The buffer output pipe 51 is connected to the material input of the first cooler 6. The material output of the first cooler 6 is equipped with a mixer 7, which is connected to a gas delivery pipe 8 for transporting carbon dioxide.

[0027] The output end of the mixer 7 is connected to a material delivery pipe 71, which is connected to the sterile storage tank 3. The material delivery pipe 71 is provided with a sterile liquid ratio regulating valve 711. The mixer 7 described in this embodiment adopts a Venturi mixer. The Venturi mixer is simple and practical, and has a good mixing effect.

[0028] A storage tank output pipe 31 is provided at the bottom of the sterile storage tank 3. A second sterile centrifugal pump 311 is installed on the storage tank output pipe 31. A storage tank drain valve 35 is installed on the storage tank output pipe 31 between the second sterile centrifugal pump 311 and the sterile storage tank 3. In this embodiment, the storage tank drain valve 35 is a T-type valve. Connected to the T-type valve are a shielded steam inlet pipe 36 with a pneumatic butterfly valve 361 and a condensate drain pipe 37. The condensate drain pipe 37 is equipped with a second temperature sensor 371 and a second steam trap 372. During the carbonated beverage preparation process, the storage tank drain valve 35 is closed, the pneumatic butterfly valve 361 is opened, and shielded steam is introduced into the shielded steam inlet pipe 36. This isolates and protects the valve seat seal of the T-type valve (storage tank drain valve 35), ensuring normal production even after the seal fails and preventing bacterial contamination of the carbonated beverage.

[0029] The gas delivery pipe 8 is sequentially equipped with a first delivery control valve, a gas delivery pressure reducing valve 82, a gas delivery check valve 83, a sterilizing filter, a second delivery control valve 85, a carbon dioxide flowmeter 86, a carbon dioxide aseptic ratio regulating valve 87, and a third delivery control valve 88, along the direction of carbon dioxide delivery. The first delivery control valve comprises a first delivery manual ball valve 811 and a first delivery angle seat valve 812, arranged in that order along the direction of carbon dioxide delivery. For ease of cleaning, both the second and third delivery control valves 85 and 88 are pneumatic diaphragm valves.

[0030] In this embodiment, the sterilizing filter includes a first sterilizing filter 841 and a second sterilizing filter 842 arranged in sequence along the direction of carbon dioxide gas transmission. The bottom of the first sterilizing filter 841 is connected to a first sterilizing filtration discharge valve 8411, and the bottom of the second sterilizing filter is connected to a second sterilizing filtration discharge valve 8421. The first sterilizing filtration discharge valve 8411 and the second sterilizing filtration discharge valve 8421 are both connected to a filtration sterilization discharge pipe 843, and a first temperature sensor 845 and a first steam trap 846 are provided on the filtration sterilization discharge pipe 843.

[0031] A backpressure line 32 is provided at the top of the sterile storage tank 3. This line is connected to the gas delivery pipe 8 between the carbon dioxide flowmeter 86 and the second delivery control valve 85. A backpressure control valve is also provided on this line. In this embodiment, the backpressure control valve includes a pneumatic backpressure diaphragm valve 321 and a manual backpressure diaphragm valve 322. A safety exhaust pipe 323 is provided on this line, which is equipped with a safety valve 3231. A backpressure exhaust pipe 324 is also connected to this line, which is equipped with a pneumatic backpressure diaphragm valve 3241. A storage tank pressure sensor 38 is also provided on the top of the sterile storage tank 3.

[0032] In this embodiment, a cleaning ball 33 with several spray holes is provided on the top of the sterile storage tank 3. The cleaning ball 33 is connected to the spray pipeline 34 outside the sterile storage tank 3. The spray pipeline 34 is connected to the material conveying pipe 71 between the mixer 7 and the material-liquid sterile proportion regulating valve 711. A spray pipeline pneumatic diaphragm valve 341 is provided on the spray pipeline 34 near the connection position with the material conveying pipe 71.

[0033] The first sterile centrifugal pump 511 and the second sterile centrifugal pump 311 are respectively provided with a sealed water inlet pipe and a sealed drain pipe. The sealed water inlet pipes are both connected to the sealed water delivery pipe 9, which is connected to the output end of the cooler 91. The input end of the cooler 91 is connected to the steam delivery pipe 10 for delivering clean steam. The condensed water of the clean steam is used as the sealing and lubricating water for the first sterile centrifugal pump 511 and the second sterile centrifugal pump 311, further effectively reducing the risk of bacteria invading the pipelines.

[0034] The specific process for preparing a carbonated beverage is as follows: Deaerated water is delivered to the mixing line 4 via the degassing tank output pipe 121. Syrup is delivered to the mixing line 4 via the syrup output pipe 111. A water flow meter 123 monitors the water flow in real time. The water-to-syrup ratio is pre-set in the PLC controller. The syrup ratio control valve 114 adjusts the syrup flow rate in real time based on the water flow rate monitored by the water flow meter 123, ensuring that the water-to-syrup ratio is always maintained within the pre-set ratio. The liquid in the mixing line 4 enters the ultra-high temperature instantaneous sterilizer 2 for sterilization. The sterilized liquid is then stored in the sterile storage tank 3. The sterilized liquid in the sterile storage tank 3 is pumped by the first sterile centrifugal pump 511 through the first cooler 6 to a temperature suitable for acidification before entering the mixer 7.

[0035] The carbon dioxide gas passes through the first delivery manual ball valve 811 and the first delivery gas angle seat valve 812 in sequence, and is reduced to an appropriate pressure through the gas delivery pressure reducing valve 82, and then enters the first sterilizing filter 841 and the second sterilizing filter 842 through the gas delivery one-way valve 83 for two-stage sterilization filtration.

[0036] After sterilization and filtration, a portion of the carbon dioxide enters the sterile storage tank 3 via the backpressure line 32, ensuring a certain pressure within the sterile storage tank 3 and preventing the escape of carbon dioxide from the liquid within the sterile storage tank 3. The storage tank pressure sensor 38 monitors the pressure within the sterile storage tank 3 in real time. If the pressure is insufficient, the backpressure pneumatic diaphragm valve 321 is opened, allowing carbon dioxide to continue entering the sterile storage tank 3 until the required pressure is reached. If the pressure exceeds the required value, the backpressure discharge pneumatic diaphragm valve 3241 is opened to vent the gas. If the pressure within the sterile storage tank 3 is too high, the safety valve 3231 opens to release the pressure.

[0037] The other part of the carbon dioxide after sterilization and filtration passes through the gas delivery pipe 8, and in turn passes through the carbon dioxide flowmeter 86, the carbon dioxide aseptic proportion regulating valve 87, and the third delivery control valve 88 into the mixer 7. After the carbon dioxide is mixed with the liquid in the mixer 7, it enters the sterile storage tank 3 from the output end of the mixer 7 through the material delivery pipe 71. The ratio of the liquid to the carbon dioxide is set in advance in the PLC controller. The carbon dioxide aseptic proportion regulating valve 87 adjusts the carbon dioxide flow rate in real time according to the liquid flow rate monitored by the liquid flowmeter 512, thereby ensuring that the ratio of the liquid to the carbon dioxide is always mixed according to the pre-set ratio. The liquid mixed with carbon dioxide in the sterile storage tank 3 is output to the outside through the storage tank output pipe 31 for filling under the action of the second sterile centrifugal pump 311.

[0038] In the aseptic carbonated beverage preparation device described above, the entire pipeline from the aseptic buffer tank 5 to the aseptic storage tank 3 is a sterile pipeline. The following describes the specific process of sterile pipeline cleaning liquid online cleaning (CIP) and steam online sterilization (SIP).

[0039] Sterile pipeline washing liquid online cleaning CIP: External washing liquid is introduced from the connection between the sterile buffer tank 5 and the buffer output pipe 51, and enters the sterile buffer tank 5 and the buffer delivery pipe 51 respectively. Usually, the sterile buffer tank 5 and the buffer output pipe 51 are connected through a cross anti-mixing valve, and the external washing liquid is introduced through the cross anti-mixing valve. The washing liquid sprays and cleans the sterile buffer tank 5, and then is discharged from the bottom discharge pipe of the sterile buffer tank 5. The washing liquid in the buffer delivery pipe 51 passes through the first sterile centrifugal pump 511, the material-liquid flowmeter 512, the first cooler 6, and the mixer 7 in sequence; the washing liquid is divided at the mixer 7 and enters the material delivery pipe 71 and the gas delivery pipe 8 respectively.

[0040] Second delivery control valve 85 on gas delivery pipe 8 is closed. The cleaning liquid in gas delivery pipe 8 enters backpressure line 32 via third delivery control valve 88, aseptic carbon dioxide ratio regulating valve 87, and carbon dioxide flowmeter 86. The cleaning liquid in backpressure line 32 then flows sequentially through backpressure pneumatic diaphragm valve 321 and manual backpressure diaphragm valve 322 into sterile storage tank 3. Backpressure exhaust pneumatic diaphragm valve 3241 is intermittently opened to clean backpressure exhaust pipe 324.

[0041] The pneumatic diaphragm valve 341 on the spray line 34 opens. A portion of the washing liquid in the material conveying pipe 71 is sprayed by the cleaning ball 33 through the spray line 34 into the sterile storage tank 3, thereby spray-cleaning the inner wall of the sterile storage tank 3. Another portion of the washing liquid in the material conveying pipe 71 enters the sterile storage tank 3 through the material-liquid sterile ratio regulating valve 711, thereby cleaning the entire material conveying pipe 71.

[0042] The cleaning liquid in the sterile storage tank 3 is pumped outward through the first storage tank output pipe 31 to the filling machine by the second sterile centrifugal pump 311 to clean the filling machine. The pneumatic butterfly valve 361 is closed, and the storage tank discharge valve 35 is intermittently opened, thereby washing the valve cavity of the storage tank discharge valve 35 with the cleaning liquid. The cleaning liquid is then discharged from the condensate drain pipe 37 through the second steam trap 372.

[0043] Sterile Pipeline Steam In-Place Sterilization (SIP): High-temperature steam is introduced from the connection between the sterile buffer tank 5 and the buffer output pipe 51, entering the sterile buffer tank 5 and the buffer delivery pipe 51, respectively. Steam condensate in the sterile buffer tank 5 is discharged from the bottom drain pipe of the sterile buffer tank 5. The steam in the buffer delivery pipe 51 flows through the first sterile centrifugal pump 511, the material-liquid flowmeter 512, and the first cooler 6, entering the mixer 7. At the mixer 7, the steam is divided and enters the material delivery pipe 71 and the gas delivery pipe 8, respectively.

[0044] The second delivery control valve 85 on the gas delivery pipe 8 is in the open state, and the steam in the gas delivery pipe 8 passes through the third delivery control valve 88, the carbon dioxide sterile proportion regulating valve 87, the carbon dioxide flowmeter 86, the second delivery control valve 85, the first sterilizing filter 841, the second sterilizing filter 842, the first sterilizing filter discharge valve 8411 and the second sterilizing filter discharge valve 8421 are opened, and the condensed water is discharged from the first steam trap 846.

[0045] The steam in the gas delivery pipe 8 will also enter the sterile storage tank 3 through the back pressure pneumatic diaphragm valve 321 and the back pressure manual diaphragm valve 322 on the back pressure pipeline 32 .

[0046] A portion of the steam in the material conveying pipe 71 enters the sterile storage tank 3 through the material-liquid sterile ratio regulating valve 711, and another portion of the steam enters the spray line 34. The spray line pneumatic diaphragm valve 341 on the spray line 34 is opened, and the steam is sprayed into the sterile storage tank 3 through the cleaning ball 33, thereby steam sterilizing the inner wall of the sterile storage tank 3.

[0047] The steam in the sterile storage tank 3 is pumped out of the storage tank output pipe 31 to the filling machine via the second sterile centrifugal pump 311, thereby steam sterilizing the filling machine. The pneumatic butterfly valve 361 is closed, and the storage tank drain valve 35 is opened, thereby sterilizing the valve cavity of the storage tank drain valve 35. Condensate is then discharged from the condensate drain pipe 37 via the second steam trap 372.

[0048] The steam sterilization timing starts when the first temperature sensor 845 and the second temperature sensor 371 detect that the temperature reaches a preset temperature.

[0049] The advantage of the present invention is that the structure of the aseptic carbonated beverage preparation apparatus ensures that all equipment and pipelines through which the material flows after exiting the ultra-high temperature instantaneous sterilizer 2 can undergo online cleaning (CIP) with detergent and online sterilization (SIP) with steam, thereby ensuring the sterility of the entire pipeline. During the beverage preparation process, it was found that sugar water could splash into the gas delivery pipe 8 that transports carbon dioxide gas, which could lead to bacterial growth. In the present invention, a second delivery control valve 85 and a third delivery control valve 88 are provided in the gas delivery pipe 8 connected to the mixer 7. Therefore, this section of the pipeline that transports carbon dioxide gas can also undergo effective online cleaning (CIP) and online steam sterilization (SIP), further ensuring the sterility of all pipelines.
