Description

Technical Field

[0001] The present application relates to the technical field of beer production and processing equipment, and in particular to a ceramic membrane beer filtering equipment. Background Art

[0002] Beer filtration is an important part of improving beer quality. At present, the common beer filtration methods in China mainly include diatomaceous earth filtration and organic membrane (such as polyethersulfone) filtration. These two methods are widely used in practice and can effectively remove suspended matter and microorganisms to ensure the clarity and taste of beer. However, with the increasing demand of consumers for high-quality beer, traditional filtration methods have gradually shown some limitations, especially in terms of high efficiency, low energy consumption and environmental protection.

[0003] In order to overcome the above problems, in recent years, more and more beer manufacturers have begun to adopt ceramic membrane filtration technology to replace traditional filtration methods. Ceramic membranes have the characteristics of high temperature resistance, good chemical stability, and long service life, and can maintain stable filtration performance for a long time. Specifically, the commonly used ceramic membrane beer filtration system usually includes a front buffer tank, a filter ceramic module, a rear buffer tank and a corresponding piping system. In the actual operation process, the fermentation liquid is first sent to the front buffer tank, and then pumped into the filter ceramic module for filtration. The generated clear liquid is collected in the rear buffer tank, while the concentrated turbid liquid is retained in the filter ceramic module.

[0004] However, although ceramic membrane filtration technology performs well in many aspects, it still faces some challenges in practical applications. In particular, when filtering beer fermentation liquid, the accumulation of yeast and other solid particles in the filtering ceramic module will cause the filtration rate to decrease. At this time, the equipment needs to be shut down for cleaning, making it difficult to achieve continuous and efficient production. Therefore, how to effectively treat the concentrated turbid liquid in the filtering ceramic module and reduce the accumulation of yeast in the pipeline has become a technical problem that needs to be solved urgently in the current industry.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application can effectively solve the problem of large-scale accumulation of yeast in the filtration ceramic module during the beer filtration process, improve the filtration efficiency of beer, and can achieve continuous and efficient production, thereby improving production efficiency, and is more suitable for large-scale beer production processes. Specifically, when in use, the beer fermentation liquid processed by the factory is sent to the front buffer tank for storage through the fermentation liquid inlet pipe; thereafter, the fermentation liquid in the front buffer tank is sent to the clear liquid filtration ceramic module for filtration through the turbid wine supply pump and the fermentation liquid delivery pipe, and the filtered clear liquid is transported to the rear buffer tank through the clear liquid delivery pipe for collection; the concentrated liquid is retained in the clear liquid filtration ceramic module. When the concentration of the concentrated liquid in the clear liquid filtration ceramic module is higher than a certain value, resulting in a decrease in the beer filtration efficiency and a decrease in the beer output speed, the concentrated liquid outlet valve is opened, and the concentrated liquid in the clear liquid filtration ceramic module is discharged. The concentrated liquid is introduced into the turbid liquid filtration ceramic module through the concentrated liquid discharge pipe, and the concentrated liquid in the clear liquid filtration ceramic module is cleaned to ensure the filtration efficiency of the clear liquid filtration ceramic module on the beer fermentation liquid; and after the concentrated liquid entering the turbid liquid filtration ceramic module is filtered, the clear liquid flows back to the front buffer tank through the reflux pipe, and the yeast in the fermentation liquid is retained in the turbid liquid filtration ceramic module.

Specifically, the outer shell is divided into a liquid inlet area, a filtration area, and a liquid discharge area by a partition, and the ceramic membrane filter is tubular, and the two ends are connected to the liquid inlet area and the liquid discharge area respectively, which ensures the orderly flow of the liquid, reduces the risk of clogging of the ceramic membrane filter, and thus improves the filtration effect; this design not only extends the service life of the ceramic membrane filter, but also reduces the frequency of shutdown for cleaning, thereby reducing maintenance costs.

[0018] 3. The present application sets the liquid inlet area at the bottom of the shell and the liquid discharge area at the top of the shell, so that the liquid flows from bottom to top, ensuring the contact area with the ceramic membrane filter element, and further improving the filtration rate of the ceramic membrane filter element. Furthermore, by setting a first circulation pipeline on the clear liquid filtration ceramic module, the fermentation liquid can circulate between the shell of the clear liquid filtration ceramic module and the first circulation pipeline, thereby improving the fluidity of the fermentation liquid inside the clear liquid filtration ceramic module, and using the principle of cross-flow filtration to filter the beer fermentation liquid, effectively avoiding clogging on the surface of the ceramic membrane.

[0019] 4. The present application can effectively solve the problem of decreased filtration efficiency of the turbid liquid filtering ceramic module due to yeast accumulation during long-term use by setting a concentrated liquid buffer tank. Specifically, when the liquid outlet speed of the turbid liquid filtering ceramic module decreases, the yeast trapped in the turbid liquid filtering ceramic module, the concentrated liquid buffer tank, and the concentrated liquid discharge pipe is emptied through the drain port, and the CIP cleaning liquid is introduced into the concentrated liquid buffer tank through the CIP cleaning liquid inlet; then, the CIP cleaning liquid is passed through the shunt pipe and the concentrated liquid discharge pipe into the turbid liquid filtering ceramic module through the concentrated liquid supply pump to clean the yeast remaining in the turbid liquid filtering ceramic module, and the CIP cleaning liquid is returned to the concentrated liquid buffer tank through the guide pipe to achieve comprehensive cleaning of the residual yeast inside the turbid liquid filtering ceramic module, thereby restoring the filtration performance of the ceramic membrane. This design not only improves the automation level of the system and reduces the need for manual intervention, but also significantly improves the system's maintenance convenience and long-term operation stability.

[0023] The inventor of the present application has found that the existing ceramic filter module will cause the filtration rate to decrease during the filtration of beer fermentation liquid due to the accumulation of yeast and other solid particles. At this time, the equipment needs to be shut down for cleaning, which makes it difficult to achieve continuous and efficient production. To this end, the present application discloses a ceramic membrane beer filtration device, which mainly adopts the following scheme: The present application embodiment discloses a ceramic membrane beer filtration device.

[0025] Reference Figure 1 The rear buffer tank 2 is used to collect the filtered clear liquid. It can be made of stainless steel with good corrosion resistance and hygienic performance. The capacity can be adjusted according to the actual needs of the production line. The rear buffer tank 2 is connected with a clear liquid delivery pipe 21 and a clear liquid outlet pipe 22. The clear liquid delivery pipe 21 is connected with the clear liquid filtering ceramic module 3. The clear liquid delivery pipe 21 is equipped with a clear wine inlet valve 23 and a clear wine outlet valve 24. The clear wine outlet valve 24 is arranged on the side close to the clear liquid filtering ceramic module 3. The clear liquid outlet pipe 22 is equipped with a wine outlet valve 25.

[0026] Reference Figure 1 , 2The main components of the clear liquid filtration ceramic module 3 include a shell 100 and a ceramic membrane filter element 200. The shell 100 is provided with a liquid inlet area 101, a liquid discharge area 102 and a filtration area 103. The liquid inlet area 101 is arranged at the bottom position of the shell 100, and the liquid discharge area 102 is arranged at the top position of the shell 100. The liquid inlet area 101 and the filtration area 103, as well as the filtration area 103 and the liquid discharge area 102 are separated by a partition 104. The ceramic membrane filter element 200 is tubular and is provided with multiple ceramic membrane filters 200. The ceramic membrane filter element 200 is fixedly arranged in the filtration area 103, and the two ends of the ceramic membrane filter element 200 are respectively connected to the liquid inlet area 101 and the liquid discharge area 102, and the surface of the ceramic membrane filter element 200 is provided with filter holes. The fermentation liquid delivery pipe 12 is connected to the liquid inlet area 101 of the shell 100 of the clear liquid filtering ceramic module 3, the clear liquid delivery pipe 21 is connected to the filtering area 103 of the shell 100 of the clear liquid filtering ceramic module 3, and the connecting end of the clear liquid delivery pipe 21 and the shell 100 of the clear liquid filtering ceramic module 3 is close to the top of the shell 100.

[0027] Reference Figure 1 , 2 The structure of the turbid liquid filtering ceramic module 4 is the same as that of the clear liquid filtering ceramic module 3. The difference lies in the pore diameters of the ceramic membrane filter 200. Under normal circumstances, the pore diameters of the ceramic membrane filter 200 in the turbid liquid filtering ceramic module 4 are larger than those of the ceramic membrane filter 200 in the clear liquid filtering ceramic module 3.

[0028] Reference Figure 1 The discharge area 102 of the shell 100 of the clear liquid filtering ceramic module 3 is connected with a concentrated liquid discharge pipe 31, and the concentrated liquid discharge pipe 31 is connected with the liquid inlet area 101 of the shell 100 of the turbid liquid filtering ceramic module 4. The concentrated liquid discharge pipe 31 is provided with a concentrated liquid outlet valve 32, a concentrated liquid inlet valve 33 and a concentrated liquid supply pump 34. The concentrated liquid supply pump 34 is arranged between the concentrated liquid outlet valve 32 and the concentrated liquid inlet valve 33, and the concentrated liquid inlet valve 33 is arranged on the side of the concentrated liquid supply pump 34 close to the turbid liquid filtering ceramic module 4. When the concentrated liquid concentration in the clear liquid filtering ceramic module 3 reaches a certain value, the concentrated liquid outlet valve 32, the concentrated liquid inlet valve 33 and the concentrated liquid supply pump 34 are opened. At this time, part of the concentrated liquid in the clear liquid filtering ceramic module 3 enters the liquid inlet area 101 of the shell 100 of the turbid liquid filtering ceramic module 4 through the concentrated liquid discharge pipe 31.

[0029] Reference Figure 1The filtering area 103 of the shell 100 of the turbid liquid filtering ceramic module 4 is also connected with a reflux pipe 41, and the connecting end of the reflux pipe 41 and the shell 100 of the turbid liquid filtering ceramic module 4 is located near the top of the shell 100, the reflux pipe 41 is connected with the front buffer tank 1, and a reflux stop valve 42 is arranged on the reflux pipe 41; after the concentrated turbid liquid enters the shell 100 of the turbid liquid filtering ceramic module 4, the concentrated turbid liquid is filtered by the ceramic membrane filter element 200, and the filtered clear liquid is refluxed to the front buffer tank 1 through the reflux pipe 41, and the yeast in the fermentation liquid is trapped in the shell 100 of the turbid liquid filtering ceramic module 4.

[0030] Reference Figure 1 The concentrated liquid discharge pipe 31 is connected to the first circulation pipe 35, the other end of the first circulation pipe 35 is connected to the fermentation liquid delivery pipe 12, and the connecting end of the first circulation pipe 35 and the concentrated liquid discharge pipe 31 is located on the side of the concentrated liquid outlet valve 32 close to the clear liquid filtering ceramic module 3, and the connecting end of the first circulation pipe 35 and the fermentation liquid delivery pipe 12 is located on the side of the turbid wine supply pump 15 close to the clear liquid filtering ceramic module 3. A fermentation liquid circulation pump 36 is provided on the fermentation liquid delivery pipe 12 and on the side of the first circulation pipe 35 close to the clear liquid filtering ceramic module 3, so that the fermentation liquid can circulate between the shell 100 of the clear liquid filtering ceramic module 3 and the first circulation pipe 35, and the beer fermentation liquid is filtered by the principle of cross-flow filtration to improve the fluidity of the fermentation liquid in the clear liquid filtering ceramic module 3, and the beer fermentation liquid is filtered by the principle of cross-flow filtration to effectively avoid clogging on the surface of the ceramic membrane. Furthermore, by setting the liquid inlet area 101 at the bottom position of the shell 100 and the liquid discharge area 102 at the top position of the shell 100, the fermentation liquid is controlled by a circulation pump to flow from the bottom to the top in the shell 100 of the clear liquid filtration ceramic module 3, thereby ensuring the contact area with the ceramic membrane filter element 200, thereby further improving the filtration rate of the ceramic membrane filter element 200.

[0031] Specifically, the working principle of cross-flow filtration is to use a pump to push the fermentation liquid to flow parallel to the membrane surface of the ceramic membrane. The shear force generated when the fermentation liquid flows through the membrane surface removes the particles retained on the membrane surface, thereby keeping the pollution layer at a thin level to avoid clogging. In the cross-flow filtration process, the fermentation liquid to be treated flows through the surface of the ceramic membrane instead of directly penetrating the entire membrane. A part of the fermentation liquid is filtered and purified through the ceramic membrane to become a clear liquid; while the water that does not pass through the ceramic membrane is retained in the filtration ceramic module. This part of water is called concentrated turbid liquid.

[0032] Reference Figure 1The drainage area 102 of the shell 100 of the turbid liquid filtering ceramic module 4 is connected with a second circulation pipeline 43, and the other end of the second circulation pipeline 43 is connected with the concentrated liquid discharge pipeline 31. The connecting end of the second circulation pipeline 43 and the concentrated liquid discharge pipeline 31 is located between the concentrated liquid inlet valve 33 and the turbid liquid filtering ceramic module 4. A concentrated liquid circulation pump 44 is provided on the concentrated liquid discharge pipeline 31 and located on the side of the second circulation pipeline 43 close to the turbid liquid filtering ceramic module 4, so that the concentrated liquid circulates between the turbid liquid filtering ceramic module 4 and the second circulation pipeline 43, and the concentrated liquid is filtered by the principle of cross-flow filtration. The concentrated liquid circulation pump 44 controls the concentrated liquid to flow from the bottom to the top in the shell 100 of the turbid liquid filtering ceramic module 4, thereby increasing the contact area between the concentrated liquid and the ceramic membrane and improving the filtration efficiency of the concentrated liquid.

[0033] Reference Figure 1 The concentrated liquid discharge pipeline 31 is also connected to a shunt pipe 37, which is connected to the concentrated liquid buffer tank 5. The connecting end of the shunt pipe 37 and the concentrated liquid discharge pipeline 31 is located between the concentrated liquid outlet valve 32 and the concentrated liquid supply pump 34. A shut-off valve 38 is provided on the shunt pipe 37. When a large amount of concentrated liquid needs to be filtered, the shut-off valve 38 can be opened to allow the concentrated liquid to pass through the shunt pipe 37 and enter the concentrated liquid buffer tank 5 for temporary storage.

[0034] Reference Figure 1 A drain port 45 is also provided near the bottom of the shell 100 of the turbid liquid filtering ceramic module 4, and the drain port 45 is connected to the liquid inlet area 101 of the shell 100 of the turbid liquid filtering ceramic module 4. The concentrated liquid buffer tank 5 is provided with a CIP cleaning liquid inlet 51. The reflux pipe 41 is connected to a guide pipe 46, and the guide pipe 46 is connected to the concentrated liquid buffer tank 5. The connecting end of the guide pipe 46 and the reflux pipe 41 is located on the side of the reflux stop valve 42 close to the turbid liquid filtering ceramic module 4, and a return front slow valve 47 is provided on the guide pipe 46.

[0035] When too much yeast is trapped in the shell 100 of the turbid liquid filtering ceramic module 4, resulting in a decrease in the liquid discharge speed, the drain port 45 is opened to drain the yeast and all the concentrated liquid trapped in the turbid liquid filtering ceramic module 4, the concentrated liquid buffer tank 5, and the concentrated liquid discharge pipe 31. After that, the drain port 45 is closed, and the CIP cleaning liquid is introduced into the concentrated liquid buffer tank 5 through the CIP cleaning liquid inlet 51; then, the CIP cleaning liquid is passed through the shunt pipe 37 and the concentrated liquid discharge pipe 31 into the turbid liquid filtering ceramic module 4 through the concentrated liquid supply pump 34, and the yeast remaining in the turbid liquid filtering ceramic module 4 is cleaned. The CIP cleaning liquid then returns to the concentrated liquid buffer tank 5 through the guide pipe 46, and the residual yeast in the turbid liquid filtering ceramic module 4 is fully cleaned, thereby restoring the filtering performance of the ceramic membrane. This design not only improves the automation of the system and reduces the need for manual intervention, but also significantly improves the system's maintenance convenience and long-term operation stability.

[0036] Furthermore, in practical applications, any number of clear liquid filtering ceramic modules 3 and turbid liquid filtering ceramic modules 4 can be set and connected in parallel to the corresponding modules of the system. When multiple clear liquid filtering ceramic modules 3 and turbid liquid filtering ceramic modules 4 are used in parallel, each module is filtered or cleaned alternately in turn to achieve the purpose of continuous filtration.

[0037] The implementation principle of the ceramic membrane beer filtration device of the embodiment of the present application is as follows: when in use, the beer fermentation liquid processed by the factory is sent to the front buffer tank 1 for storage through the fermentation liquid inlet pipe 11; then, the fermentation liquid in the front buffer tank 1 is sent to the clear liquid filtration ceramic module 3 for filtration through the turbid wine supply pump 15 and the fermentation liquid delivery pipe 12, and the filtered clear liquid is delivered to the rear buffer tank 2 through the clear liquid delivery pipe 21 for collection; the concentrated turbid liquid is retained in the clear liquid filtration ceramic module 3, and when the concentration of the concentrated turbid liquid in the clear liquid filtration ceramic module 3 is higher than a certain concentration, the concentrated turbid liquid in the clear liquid filtration ceramic module 3 is filtered. When the value is low, resulting in a decrease in the filtration efficiency of beer and a decrease in the beer outlet speed, the concentrated liquid outlet valve 32 is opened, and the concentrated liquid in the clear liquid filtration ceramic module 3 is introduced into the turbid liquid filtration ceramic module 4 through the concentrated liquid discharge pipe 31, and the concentrated liquid in the clear liquid filtration ceramic module 3 is cleaned to ensure the filtration efficiency of the clear liquid filtration ceramic module 3 on the beer fermentation liquid; and after the concentrated liquid entering the turbid liquid filtration ceramic module 4 is filtered, the clear liquid flows back to the front buffer tank 1 through the reflux pipe 41, and the yeast in the fermentation liquid is retained in the turbid liquid filtration ceramic module 4.

[0038] When too much yeast is trapped in the shell 100 of the turbid liquid filtering ceramic module 4, resulting in a decrease in the liquid discharge speed, the drain port 45 is opened to drain the yeast and all the concentrated liquid trapped in the turbid liquid filtering ceramic module 4, the concentrated liquid buffer tank 5, and the concentrated liquid discharge pipe 31. After that, the drain port 45 is closed, and the CIP cleaning liquid is introduced into the concentrated liquid buffer tank 5 through the CIP cleaning liquid inlet 51; then, the CIP cleaning liquid is allowed to enter the turbid liquid filtering ceramic module 4 through the shunt pipe 37 and the concentrated liquid discharge pipe 31 through the concentrated liquid supply pump 34, and the yeast remaining in the turbid liquid filtering ceramic module 4 is cleaned. The CIP cleaning liquid then returns to the concentrated liquid buffer tank 5 via the guide pipe 46, thereby achieving a comprehensive cleaning of the residual yeast inside the turbid liquid filtering ceramic module 4, thereby restoring the filtering performance of the ceramic membrane. The present application can effectively solve the problem of large-scale accumulation of yeast in the filter ceramic module during the beer filtration process, improve the filtration efficiency of beer, and achieve continuous and efficient production, thereby improving production efficiency and being more suitable for large-scale beer production processes.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
