Technical Field

[0001] This utility model relates to the field of cross-flow filtration technology, specifically a beer filtration device that applies cross-flow filtration technology. Background Technology

[0002] Cross-flow filtration has been widely used in beer and beverage production as well as liquid food. After fermentation, beer contains a large amount of yeast, fermentation byproducts and other impurities. In order to ensure the stability of beer and improve its shelf life, beer needs to be filtered to separate yeast and other impurities from the beer. Cross-flow filtration has gradually become the mainstream of modern equipment, replacing diatomaceous earth filtration and cardboard filtration.

[0003] A search revealed a hop churn device using cross-flow filtration disclosed in Chinese utility model patent CN202321694126.4. This device offers flexibility in operation through cross-flow filtration, allowing for both intermittent and continuous operation, significantly improving production efficiency. However, it can only filter beer through a single filter membrane, leaving residues smaller than the membrane pore size, resulting in poor filtration. Therefore, a beer filtration device using cross-flow filtration technology is proposed to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a beer filtration device that utilizes cross-flow filtration technology. This device offers advantages such as higher filtration efficiency and better filtration effect, solving the problem that during use, beer can only be filtered through a single filter membrane, resulting in residues smaller than the pore size of the filter membrane remaining in the beer and thus leading to poor filtration performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a beer filtration device using cross-flow filtration technology, comprising a base, a raw liquid tank fixedly installed on the top of the base, a storage tank fixedly installed on the top of the base, and a filtration mechanism provided on the top of the base;

[0006] The filtration mechanism includes a first filter tank, which is mounted on the top of the base. A second filter tank is mounted on the right side of the first filter tank.

A return pipe is connected to the top of the raw liquid tank, and a first diverter pipe and a second diverter pipe are connected to the bottom of the return pipe. A first filter membrane assembly is installed on the inner wall of the first filter tank, and a second filter membrane assembly is installed on the inner wall of the second filter tank.

[0007] Furthermore, a display window is fixedly installed on the front side of the raw liquid tank, and a slag discharge pipe is connected to the bottom of the raw liquid tank.

[0008] Furthermore, the side of the first water inlet pipe away from the original liquid tank is connected to the bottom of the first filter tank, and the side of the second water inlet pipe away from the first filter tank is connected to the bottom of the second filter tank.

[0010] Furthermore, a scale is provided on the front side of the storage tank, an injection pipe is connected to the left side of the raw liquid tank, and a discharge pipe is connected to the right side of the storage tank.

[0011] Furthermore, both the first and second filter membrane groups are ceramic filter membranes. The first filter membrane group includes a porous support layer, a transition layer, and a separation layer. The pore size of the first filter membrane group is 0.2 μm, and the pore size of the second filter membrane group is smaller than that of the first filter membrane group.

[0012] Furthermore, a flow meter is connected to the top of the return pipe, and one-way solenoid valves are connected to the outside of the first inlet pipe, the second inlet pipe, the return pipe, the first branch pipe, and the second branch pipe.

[0021] Please see Figure 1-3 A beer filtration device using cross-flow filtration technology in this embodiment includes a base 1, a raw liquid tank 2 fixedly installed on the top of the base 1, a storage tank 3 fixedly installed on the top of the base 1, and a filtration mechanism 4 provided on the top of the base 1.

[0022] The filtration mechanism 4 includes a first filter tank 401, which is mounted on the top of the base 1. A second filter tank 402 is mounted on the right side of the first filter tank 401. A first water inlet pipe 403 is connected to the bottom of the raw liquid tank 2. A second water inlet pipe 404 is connected to the right side of the first filter tank 401. A return pipe 405 is connected to the top of the raw liquid tank 2. A first diverter pipe 406 is connected to the bottom of the return pipe 405. A second diverter pipe 407 is connected to the bottom of the return pipe 405. A first filter membrane assembly 408 is installed on the inner wall of the first filter tank 401. A second filter membrane assembly 409 is installed on the inner wall of the second filter tank 402.

[0023] exist Figure 1 and Figure 2 In the middle, a display window is fixedly installed on the front side of the raw liquid tank 2, and a slag discharge pipe 5 is connected to the bottom of the raw liquid tank 2.

[0024] Specifically, after multiple filtrations, a large amount of residue is stored in the original liquid tank 2. At this time, the one-way solenoid valve is activated, and the lees are discharged through the lees discharge pipe 5.

[0025] exist Figure 1 and Figure 2 In the first water inlet pipe 403, the side away from the original liquid tank 2 is connected to the bottom of the first filter tank 401, and the side away from the first filter tank 401 is connected to the bottom of the second filter tank 402.

[0026] Specifically, by setting the first filter tank 401 and the second filter tank 402 to limit the first filter membrane group 408 and the second filter membrane group 409, the one-way solenoid valve on the first water inlet pipe 403 is activated. At this time, the beer enters the first filter tank 401 through the first water inlet pipe 403, and the first filter membrane group 403 can then perform coarse filtration of the beer through the porous support layer, transition layer and separation layer.

[0027] exist Figure 1 and Figure 3 In the middle, the side of the return pipe 405 away from the original liquid tank 2 is connected to the top of the second filter tank 402 through the second diversion pipe 407.

[0028] Specifically, the residue after double filtration is poured back to the original liquid tank 2 through the return pipe 405, which facilitates multiple filtration cycles and ensures better filtration results.

[0029] exist Figure 2 and Figure 3 In the middle, a scale is set on the front side of the storage tank 3, an injection pipe is connected to the left side of the raw liquid tank 2, and a discharge pipe is connected to the right side of the storage tank 3.

[0030] exist Figure 2 and Figure 3 In this process, both the first filter membrane group 408 and the second filter membrane group 409 are ceramic filter membranes. The first filter membrane group 408 includes a porous support layer, a transition layer and a separation layer. The pore size of the first filter membrane group 408 is 0.2 μm, and the pore size of the second filter membrane group 409 is smaller than that of the first filter membrane group 408.

[0031] Specifically, filtration is performed through a first filter membrane group 408 and a second filter membrane group 409 with different pore sizes, thereby ensuring better filtration effect.

[0032] exist Figure 2 and Figure 3 In the middle, a flow meter 6 is connected to the top of the return pipe 405. One-way solenoid valves are connected to the outside of the first inlet pipe 403, the second inlet pipe 404, the return pipe 405, the first branch pipe 406, and the second branch pipe 407. A conduit 7 is connected to the right side of the second filter tank 402, and the right side of the conduit 7 is connected to the storage tank 3.

[0033] During implementation, the following steps are performed: First, fill the original liquid tank 2 through the injection pipe. When beer filtration is required, the controller first drives the booster pump outside the first inlet pipe 403 to start. At this time, the beer enters the first filter tank 401 through the first inlet pipe 403. The first filter membrane assembly 403 then performs coarse filtration of the beer through the porous support layer, transition layer, and separation layer. At this time, some of the fermented beer flows over the upper end of the first filter membrane assembly 408 due to flow shear force. The solenoid valve is activated, and the beer enters the return pipe 405 through the first diversion pipe 406 and returns to the original liquid tank 2 through the return pipe 405. The remaining beer enters the second filter tank 402 through the second inlet pipe 404. At this time, some of the fermented beer flows over the upper end of the second filter membrane assembly 409 due to flow shear force and returns to the original liquid tank 2 through the return pipe 405. The remaining beer after secondary filtration enters the storage tank 3 through the conduit 7, thus completing the filtration process.

[0034] In summary, by setting up the first filter tank 401 and the second filter tank 402 to limit the movement of the first filter membrane group 408 and the second filter membrane group 409, the one-way solenoid valve on the first water inlet pipe 403 is activated. At this time, the beer enters the first filter tank 401 through the first water inlet pipe 403. The first filter membrane group 403 can then perform coarse filtration of the beer through the porous support layer, transition layer, and separation layer. At this time, some of the fermented beer liquid flows over the upper end of the first filter membrane group 408 due to the flow shear force, and the solenoid valve is activated. The liquid enters the return pipe 405 through the first branch pipe 406 and returns to the original liquid tank 2 through the return pipe 405. By setting the second filter membrane group 409, part of the liquid that has been filtered by the first filter membrane group 408 is introduced into the second filter membrane group 409 through the second water inlet pipe 403. At this time, part of the fermented beer liquid flows through the upper end of the second filter membrane group 409 under the action of flow shear force and returns to the original liquid tank 2 through the return pipe 405. The remaining liquid that has been filtered twice enters the storage tank 3 through the conduit 7, thus completing the filtration.
