Description

Technical Field

[0001] This invention belongs to the field of beer processing and production technology, specifically relating to a connection structure and adjustment method between a beer membrane filtration system and a beer filling machine. Background Technology

[0002] Draft beer is beer that has not undergone pasteurization or ultra-high temperature sterilization, but has been sterilized using other physical methods to achieve a certain level of biological stability. Filtering beer using beer filter cartridges made with polyethersulfone microporous membranes with a pore size of 0.2μm is a common physical method in the production of draft beer. The equipment that installs the beer filter cartridges is called a beer membrane filtration system. Installed before the beer bottling machine, the beer passes through the membrane filtration system before entering the bottling machine's tanks, and then is filled into beer containers.

[0003] Normally, beer membrane filtration systems and bottling machines are designed, installed, commissioned, and put into use simultaneously. However, with the increasing demand for draft beer, some breweries are adding beer membrane filtration systems to their existing beer production lines to meet the requirements for producing draft beer. This results in a situation where the beer bottling machine and beer membrane filtration system are not installed synchronously. If the modification were to follow a synchronous installation plan, it would require purchasing many valves and making significant adjustments to the piping layout, leading to high costs and additional production costs.

[0027] S1. When filling pure draft beer: The sake in the sake tank is pumped by the sake pump assembly, the double seat valve is opened, and it enters the membrane filter primary filter and membrane filter final filter through the first pipeline and the second pipeline.

[0031] Preferably, in step S1, the second regulating valve is fully open, and the liquid level of the beer filling machine is controlled by the first regulating valve. When the liquid level of the beer filling machine is >200mm, the opening of the first regulating valve decreases, and when the liquid level of the beer filling machine is <200mm, the opening of the first regulating valve increases to maintain the liquid level of the beer filling machine at 200mm. The opening of the beer pump assembly is controlled by the first pressure transmitter.

[0032] In step S2, the first regulating valve is fully open, and the liquid level of the beer filling machine is controlled by the second regulating valve. When the liquid level of the beer filling machine is >200mm, the opening of the second regulating valve decreases, and when the liquid level of the beer filling machine is <200mm, the opening of the second regulating valve increases to maintain the liquid level of the beer filling machine at 200mm. The opening of the beer pump assembly is controlled by the second pressure transmitter. When the pressure of the second pressure transmitter is >3200mbar, the opening of the beer pump assembly decreases, and when the pressure of the second pressure transmitter is <3200mbar, the opening of the beer pump assembly increases to maintain the pressure of the second pressure transmitter at 3200mbar.

[0033] Preferably, in step S3, the liquid level of the beer filling machine is controlled by the second regulating valve.

[0044] Beer membrane filtration system and beer filling machine 25;

The pressure transmitter includes a first pressure transmitter 11 and a second pressure transmitter 12. The regulating valve includes a first regulating valve 13 and a second regulating valve 14. The wine pump assembly, the first pressure transmitter 11, the first regulating valve 13, the second pressure transmitter 12, and the second regulating valve 14 are arranged on the first pipeline 8 along the flow direction from the first inlet end 3 to the first outlet end 5.

[0051] The second pressure transmitter 12 is electrically connected to the beer pump assembly and the first pressure transmitter 11, respectively, and the first regulating valve 13 is electrically connected to the second regulating valve 14 and the beer filling machine 25, respectively.

[0052] Specifically, the first inlet end 3 is connected to the output port of the sake tank;

[0053] The second inlet 4 connects to the output port of the CIP cleaning system;

[0054] The first outlet 5 is connected to the input port of the CIP cleaning system.

[0055] Specifically, the wine pump assembly includes a wine delivery pump 15 and a wine pump frequency converter 16. The wine delivery pump 15 is connected to the first inlet end 3 and is electrically connected to the first pressure transmitter 11, the second pressure transmitter 12, and the wine pump frequency converter 16.

[0056] Specifically, the pneumatic valves are respectively designated as the first pneumatic valve 17, the second pneumatic valve 18, the third pneumatic valve 19, the fourth pneumatic valve 20, the fifth pneumatic valve 21, the sixth pneumatic valve 22, the seventh pneumatic valve 23 and the eighth pneumatic valve 24;

[0057] The first pneumatic valve 17, the second pneumatic valve 18, the third pneumatic valve 19, and the fourth pneumatic valve 20 are located in the first pipeline 8;

[0058] The fifth pneumatic valve 21, the sixth pneumatic valve 22, and the seventh pneumatic valve 23 are located in the second pipeline 9;

[0059] The eighth pneumatic valve 24 is located in the third pipeline 10.

[0060] Specifically, the second pneumatic valve 18 and the third pneumatic valve 19 are located between the first pneumatic valve 17 and the beer filling machine 25, the double-seat valve 6 is located between the first pneumatic valve 17 and the second pneumatic valve 18, and the fourth pneumatic valve 20 is located between the beer filling machine 25 and the first outlet end 5.

[0061] Specifically, the double-seat valve 6 is located between the fifth pneumatic valve 21 and the sixth pneumatic valve 22, and the membrane filter pre-filter 1 and the membrane filter final filter 2 are located between the sixth pneumatic valve 22 and the seventh pneumatic valve 23.

[0062] Specifically, the first regulating valve 13 and the second regulating valve 14 are of the same model, and Q-100 regulating valves can be selected. The pressure transmitter of the first regulating valve 13 is electrically connected to the first pressure transmitter 11, and the second regulating valve 14 is electrically connected to the second pressure transmitter 12.

[0063] This invention also includes an adjustment method for a beer membrane filtration system and a beer filling machine, applied to the connection structure of the aforementioned beer membrane filtration system and beer filling machine, comprising the following steps:

[0064] S1. When filling pure draft beer: The sake in the sake tank is pumped by the sake pump assembly, the double seat valve 6 is opened, and it enters the membrane filter primary filter 1 and membrane filter final filter 2 through the first pipeline 8 and the second pipeline 9. After the beer is filtered, it enters the beer filling machine 25 through the pneumatic valve and the regulating valve, and is filled in the beer filling machine 25.

[0065] S2. When filling pasteurized beer: the membrane filter primary filter 1 and the membrane filter final filter 2 are in an idle state, the beer filling machine 25 runs the production program: the double seat valve 6 is closed, and the beer in the beer tank is pumped by the beer pump assembly and directly enters the beer filling machine 25 for filling through the first pipeline 8.

[0066] S3. When the filling machine is in CIP cleaning mode: the membrane filter primary filter 1 and the membrane filter final filter 2 are in an idle state. The beer filling machine 25 runs the CIP cleaning program: the double seat valve 6 is opened, and the CIP cleaning fluid of the CIP cleaning system enters the beer filling machine 25 through the second pipeline 9 and the first pipeline 8, and then flows back to the CIP cleaning system through the first outlet end 5.

[0067] S4. When the membrane filtration system is in CIP cleaning state: the beer filling machine 25 is in an idle state, and the membrane primary filter 1 and the membrane final filter 2 are running the CIP cleaning program: the CIP cleaning solution enters the membrane primary filter 1 and the membrane final filter 2 through the second pipeline 9, and then flows back to the CIP cleaning system through the first outlet end 5.

[0068] Specifically, in step S1, the second regulating valve 14 is fully open, and the liquid level of the beer filling machine 25 is controlled by the first regulating valve 13. When the liquid level of the beer filling machine 25 is >200mm, the opening of the first regulating valve 13 decreases; when the liquid level of the beer filling machine 25 is <200mm, the opening of the first regulating valve 13 increases, maintaining the liquid level of the beer filling machine 25 at 200mm. The opening of the beer pump assembly is controlled by the first pressure transmitter 11. When the pressure of the first pressure transmitter 11 is >3500mbar, the opening of the beer pump assembly decreases; when the pressure of the first pressure transmitter 11 is <3500mbar, the opening of the beer pump assembly increases, maintaining the pressure of the first pressure transmitter 11 at 3500mbar.

[0069] In step S2, the first regulating valve 13 is fully open, and the liquid level of the beer filling machine 25 is controlled by the second regulating valve 14. When the liquid level of the beer filling machine 25 is >200mm, the opening of the second regulating valve 14 decreases, and when the liquid level of the beer filling machine 25 is <200mm, the opening of the second regulating valve 14 increases to maintain the liquid level of the beer filling machine 25 at 200mm. The opening of the beer pump assembly is controlled by the second pressure transmitter 12. When the pressure of the second pressure transmitter 12 is >3200mbar, the opening of the beer pump assembly decreases, and when the pressure of the second pressure transmitter 12 is <3200mbar, the opening of the beer pump assembly increases to maintain the pressure of the second pressure transmitter 12 at 3200mbar.

[0070] Specifically, in step S3, the liquid level of the beer filling machine 25 is controlled by the second regulating valve 14.

[0071] This technical solution achieves the following effects by optimizing equipment layout and modifying control programs:

[0072] (1) A first regulating valve 13 is added. During production, the second regulating valve 14 is fully open. The first regulating valve 13 controls the liquid level of the beer filling machine 25. The effects of instantaneous pressure fluctuations and pressure shocks can be controlled before the first regulating valve 13, effectively reducing damage to the beer filter element, extending the membrane filtration life, and reducing the risk of microorganisms penetrating the filter membrane.

[0073] (2) Only one regulating valve and one pressure transmitter are added, which requires minimal modification to the equipment and piping, does not require additional space, and has a low modification cost, estimated at 200,000 yuan. If the beer membrane filtration system and beer filling machine are designed and installed simultaneously, although the usage of other membrane filtration systems can be achieved, the modification requires the addition of several double-seat valves and related pipelines, and the equipment modification requires an investment of about 1 million yuan. In addition, the existing equipment layout needs to be significantly adjusted, the modification space requirement is large, and other nearby equipment such as conveyor belts need to be adjusted at the same time, making the modification difficult to implement.

[0074] (3) The control program of the beer filling machine 25 requires only minor modifications. Based on the production / cleaning status of the beer filling machine 25, the corresponding first regulating valve 13 and second regulating valve 14 can be controlled. Additionally, the control signal of the beer pump assembly only needs to be associated with the newly added pressure transmitter. The estimated investment is 50,000 yuan. If the equipment layout is modified according to the simultaneous design and installation of the beer membrane filtration system and the beer filling machine, and then the relevant control program is modified, there will be more modifications required, with an estimated investment of 300,000 yuan.

[0075] The control program for the aforementioned beer filling machine 25 is modified as follows:

[0076] (1) Modify the control program of the beer filling machine 25. Based on the operating status of the beer filling machine 25 and the beer membrane filtration system, determine whether the liquid level in the beer tank of the beer filling machine 25 is controlled by the first regulating valve 13 or the second regulating valve 14. When both the beer filling machine 25 and the beer membrane filtration system are in production, control the second regulating valve 14 to be fully open, and the liquid level in the beer tank of the beer filling machine 25 is adjusted by controlling the opening of the first regulating valve 13. When the beer filling machine 25 is in production and the beer membrane filtration system is idle (for producing non-pure draft beer, the beer membrane filtration system is not required), control the first regulating valve 13 to be fully open, and the liquid level in the beer tank of the beer filling machine 25 is adjusted by controlling the opening of the second regulating valve 14. When the beer filling machine 25 or the beer membrane filtration system is in cleaning state, control the first regulating valve 13 to be closed, and the liquid level in the beer tank of the beer filling machine 25 is adjusted by controlling the opening of the second regulating valve 14.

[0077] (2) Modify the control program of the beer pump assembly. The opening of the beer pump assembly is changed from being controlled by the second pressure transmitter 12 before the second regulating valve 14 to being controlled by the first pressure transmitter 11 before the first regulating valve 13. The pressure of the first pressure transmitter 11 is maintained at 3500 mbar. A pressure drop will occur after passing through the beer membrane filtration system, but the beer filling machine 25 can operate normally when the pressure of the second pressure transmitter 12 before the second regulating valve 14 reaches 3200 mbar.

[0078] In summary, after the implementation of this technical solution, the production line with the beer membrane filtration system and beer filling machine installed asynchronously can achieve the same operating level as the production line with synchronous installation. Moreover, the investment in this technical solution is estimated to be only 250,000 yuan, which saves 1,050,000 yuan compared to the investment in modifying the production line by designing and installing the beer membrane filtration system and beer filling machine synchronously.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
