Description

Technical Field

[0001] This utility model belongs to the field of beer production technology, specifically relating to a carbon dioxide addition system for the beer filtration and dilution process. Background Technology

[0002] Currently, the beer filtration and dilution process requires the online addition of CO2 to ensure that the CO2 content in the beer and finished product meets product standards. Controlling the online CO2 addition system during the dilution and filtration process is a crucial step in ensuring product quality. Typically, the CO2 aeration line is directly added to the beer CO2 mixer. This method makes it difficult to guarantee the stability of the CO2 addition process and mitigates the risk of microbial contamination of the pipeline. This method lacks control over the CO2 flow rate, and it's difficult to promptly replenish the CO2 if the initial addition is insufficient, thus compromising CO2 stability. Furthermore, existing equipment is often difficult to clean, easily leading to beer contamination of the CO2 pipeline and creating a potential risk of microbial contamination of the CO2 pipeline during the beer filtration and dilution process.

[0003] Therefore, a new technology is needed to address the problems of insufficient CO2 addition and easy CO2 pipeline pollution in existing technologies. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a carbon dioxide addition system for the beer filtration and dilution process, which ensures that the CO2 content of the beer meets the standard requirements and prevents the beer from entering the CO2 pipeline and causing pipeline contamination.

[0005] The present invention adopts the following technical solution:

[0006] A carbon dioxide addition system for beer filtration and dilution includes a mixer, a liquid supply line, a gas supply line, and a CIP cleaning line. The mixer has a mixing chamber for dissolving CO2 in the beer liquid. The beer liquid flows into the mixing chamber through the liquid supply line, and a first regulating valve is provided on the liquid supply line.

[0007] The mixer is equipped with a first inlet, a second inlet, and a liquid outlet communicating with the mixing chamber. The gas supply line is connected to the mixing chamber through the first inlet and the second inlet and is used to introduce CO2 into the mixing chamber. A second regulating valve is provided between the first inlet and the gas supply line, and a third regulating valve is provided between the second inlet and the gas supply line. The CIP cleaning line is connected to the gas supply line and is used to clean the gas supply line. Check valves are installed between the gas supply line and the first inlet and the second inlet.

[0008] When the second regulating valve is fully open, if the CO2 content in the wine in the mixing chamber is less than the preset content, the third regulating valve is opened; when both the second regulating valve and the third regulating valve are fully open, if the CO2 content in the wine in the mixing chamber is less than the preset content, the opening of the first regulating valve is reduced or closed.

[0009] As a further improvement to the technical solution of this utility model, the gas supply pipeline includes a gas supply channel and a first channel, a second channel, and an venting channel. One end of the gas supply channel is provided with an air inlet connected to the gas supply equipment, and the other end is connected to one end of the first channel, the second channel, and the venting channel, respectively. The other end of the venting channel is provided with an vent. The CIP cleaning pipeline is connected to the gas supply channel and the venting channel in sequence to form a cleaning flow path. The other end of the first channel is connected to the first inlet, and the second regulating valve is installed on the first channel. The other end of the second channel is connected to the second inlet, and the third regulating valve is installed on the second channel.

[0010] As a further improvement to the technical solution of this utility model, a check valve is also included, which is installed on the air supply channel at one end away from the air inlet.

[0011] As a further improvement to the technical solution of this utility model, a pipeline switch valve is also installed on the gas supply channel, and the connection node between the CIP cleaning pipeline and the gas supply channel is located between the check valve and the pipeline switch valve.

[0012] As a further improvement to the technical solution of this utility model, a CO2 flow meter is also installed on the gas supply channel, and the CO2 flow meter is located between the pipeline switch valve and the gas inlet.

[0013] As a further improvement to the technical solution of this utility model, an air venting valve is installed on the air venting channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This beer filtration and dilution process utilizes a carbon dioxide addition system that is easy to adjust. The liquid supply line is equipped with a first regulating valve to control the flow rate of the beer entering the mixing chamber. The gas supply line connects to the mixing chamber via a first inlet and a second inlet, respectively, to introduce CO2 into the mixing chamber. A second regulating valve regulates the CO2 flow rate at the first inlet, and a third regulating valve regulates the CO2 flow rate at the second inlet. A CIP (Clean-In-Place) system can clean the gas supply line. When the second regulating valve is fully open, if the CO2 content in the beer in the mixing chamber is less than a preset level, the third regulating valve is opened to add additional CO2. When both the second and third regulating valves are fully open, if the CO2 content in the beer in the mixing chamber is less than the preset level, the opening of the first regulating valve is reduced or closed to ensure that the beer's CO2 content meets the requirements.

[0016] This solution ensures that the CO2 content of the beer meets the standard requirements by controlling the first, second, and third regulating valves. By connecting a cleaning CIP pipeline and installing a check valve in the gas supply channel, the check valve prevents beer from entering the CO2 gas supply channel 31 and causing contamination. Furthermore, the gas supply channel 31 can be cleaned using CIP after production to ensure cleanliness and hygiene. Attached Figure Description

[0026] Reference Figure 1 A carbon dioxide addition system for beer filtration and dilution includes a mixer 1, a liquid supply line 2, a gas supply line 3, and a CIP cleaning line 4. The mixer 1 has a mixing chamber 15 for dissolving CO2 in the beer liquid. A beer outlet 14 allows the beer liquid after CO2 addition to flow out. The mixer 1 has a beer inlet 13 communicating with the mixing chamber 15, allowing the beer liquid to have CO2 added to pass through. The beer liquid to be CO2 added and the carbon dioxide are mixed in the mixing chamber 15, and the carbon dioxide dissolves in the beer liquid within the mixing chamber 15. The beer liquid to be CO2 added flows into the mixing chamber 15 through the liquid supply line 2. The liquid supply line 2 has a first regulating valve 21 for controlling the flow rate of the beer liquid entering the mixing chamber 15. The flow rate of the beer liquid entering the mixing chamber 15 can be adjusted by regulating the opening of the first regulating valve 21. The mixer 1 is equipped with a first inlet 11, a second inlet 12, and a liquor outlet 14, all connected to the mixing chamber 15. The gas supply line 3 connects to the mixing chamber 15 via the first inlet 11 and the second inlet 12, respectively, and is used to supply CO2 into the mixing chamber 15. A second regulating valve 321 is provided between the first inlet 11 and the gas supply line 3, and the second regulating valve 321 is used to control the CO2 flow rate at the first inlet 11. A third regulating valve 331 is provided between the second inlet 12 and the gas supply line 3, and the second regulating valve 321 is used to control the CO2 flow rate at the second inlet 12. The CIP cleaning line 4 connects to the gas supply line 3 and is used to clean the gas supply line 3. A check valve 312 is installed between the gas supply line 3 and the first inlet 11 and the second inlet 12. The check valve 312 prevents the liquor in the mixer 1 from being injected back into the gas supply line 31 during CO2 addition, thus preventing contamination of the gas supply line 31.

[0027] The opening of the second regulating valve 321 is adjusted according to the CO2 content. When the second regulating valve 321 is fully open, the CO2 flow rate entering the mixing chamber 15 through the second regulating valve 321 has reached its maximum. If the CO2 content in the liquid in the mixing chamber 15 is still less than the preset content, the third regulating valve 331 is opened to supplement CO2, allowing CO2 to enter the mixing chamber 15 through the third regulating valve 331, thereby supplementing the liquid in the mixing chamber 15 with CO2. When both the second regulating valve 321 and the third regulating valve 331 are fully open, the CO2 flow rate entering the mixing chamber 15 has reached its maximum. If the CO2 content in the liquid in the mixing chamber 15 is still less than the preset content, the opening of the first regulating valve 21 is adjusted to decrease or close, reducing or pausing the flow rate of the liquid entering the mixing chamber 15 to ensure that the CO2 content of the beer flowing out of the liquid outlet 14 meets the requirements. A CO2 flow meter 314 is installed on the gas supply line 3. During use, the amount of CO2 added can be controlled according to the CO2 flow data displayed by the flow meter 314 to ensure that CO2 is evenly dissolved in the beer and to avoid waste of CO2.

[0028] This solution accurately controls the online CO2 addition amount by real-time monitoring of the CO2 flow meter 314 installed on the pipeline. By controlling the second regulating valve 321, the third regulating valve 331, and the first regulating valve 21, the CO2 content of the beer can be ensured to meet standard requirements. By installing a check valve 312 on the gas supply channel 31, connecting a cleaning CIP pipeline to the gas supply channel 31, and adding an vent 342 to the vent channel 34, contamination from beer entering the CO2 gas supply channel 31 can be prevented. Furthermore, after beer production, the gas supply channel 31 is cleaned using CIP, and the cleaning solution flows out to the outside through the vent 342 of the vent channel 34, ensuring the gas supply channel 31 remains clean and hygienic.

[0029] Specifically, the gas supply pipeline 3 includes a gas supply channel 31, a first channel 32, a second channel 33, and an exhaust channel 34. The gas supply equipment is used to supply CO2 gas into the gas supply channel 31. One end of the gas supply channel 31 is provided with an air inlet 311 connected to the gas supply equipment, and the other end is connected to one end of the first channel 32, the second channel 33, and the exhaust channel 34, respectively. The other end of the exhaust channel 34 is provided with an exhaust port 342. When production ends, the gas supply channel 31 is connected to a CIP cleaning system to ensure that the gas supply channel 31 is clean and hygienic. The CIP cleaning pipeline 4 is sequentially connected to the air supply channel 31 and the venting channel 34 to form a cleaning flow path. The cleaning fluid in the CIP cleaning pipeline 4 can enter the air supply channel 31 to clean the air supply channel 31 and flow out from the venting port 342 of the venting channel 34. The other end of the first channel 32 is connected to the first inlet 11. The second regulating valve 321 is installed on the first channel 32 away from the first inlet 11. The other end of the second channel 33 is connected to the second inlet 12. The third regulating valve 331 is installed on the second channel 33 near the end of the air supply channel 31.

[0030] Specifically, the carbon dioxide addition system for the beer filtration and dilution process in this solution also includes a check valve 312, which is installed on the gas supply channel 31 at the end away from the air inlet 311. Beer cannot enter the gas supply channel 31 through the check valve 312, preventing the beer in the mixer 1 from flowing back into the gas supply channel 31 and contaminating it during CO2 addition.

[0031] Specifically, a pipeline switch valve 313 is also installed on the gas supply channel 31. The pipeline switch valve 313 is located near the air inlet 311. The connection node between the CIP cleaning pipeline 4 and the gas supply channel 31 is located between the check valve 312 and the pipeline switch valve 313. The CIP cleaning inlet on the gas supply channel 31 is located between the check valve 312 and the pipeline switch valve 313. During cleaning, the pipeline switch valve 313 can be closed to avoid contamination of the gas supply equipment and the air inlet 311.

[0032] Specifically, a CO2 flow meter 314 is also installed on the gas supply channel 31. The CO2 flow meter 314 is located between the pipeline switch valve 313 and the air inlet 311. The opening and closing of the pipeline switch valve 313 can be controlled according to the CO2 flow data displayed by the CO2 flow meter 314, thereby controlling the amount of CO2 added.

[0033] Specifically, an air vent valve 341 is installed on the air vent channel 34. The air vent valve 341 is installed on the air vent channel 34 near the air vent port 342. When performing CIP cleaning on the gas supply channel 31, the air vent valve 341 on the air vent channel 34 can be opened to allow the cleaning fluid to flow out from the air vent port 342, ensuring that the gas supply channel 31 is clean and hygienic.

[0034] Other aspects of the carbon dioxide addition system for the beer filtration and dilution process described in this utility model are found in the prior art and will not be repeated here.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
