[0016] Optionally, an anti-shock component for buffering the liquid is detachably installed in the filter cartridge, and the anti-shock component is located directly above the filter screen.

[0017] By adopting the above technical solution, the liquid is poured onto the anti-impact component, and the anti-impact component plays a buffering role on the liquid, thereby reducing the possibility of the liquid destroying the diatomaceous earth coating of part of the filter screen.

[0022] In a second aspect, the present application provides a filtration method for beer filtration, which adopts the following technical solution:

[0023] A filtration method for beer filtration, comprising the steps of: preparing a pre-coating liquid; pouring a predetermined amount of diatomaceous earth into a predetermined amount of water, and stirring the mixture evenly;

[0024] Step 2: Pressurized pre-coating: Pour the pre-coating liquid into the filter cartridge, close the top cover, pressurize to a predetermined value through the air pipe joint, collect the discharge port of the collection hopper with a predetermined container, and after collecting all the filtered liquid, pour the filtered pre-coating liquid back into the filter cartridge;

[0027] Step 5: Sampling and testing; first collect a predetermined volume of wine using a measuring cup and pour it out, then use another measuring cup to collect a predetermined volume of wine to test the turbidity.

[0028] By adopting the above technical scheme, the present application first pours the diatomaceous earth pre-coating liquid into the filter cartridge, and then pressurizes it to a predetermined value through the air pipe joint, and uses the pressure to quickly form a relatively compact diatomaceous earth coating, which is more in line with the high-flow pre-coating step in actual production; then the discharge port of the collection bucket is collected with a predetermined container, and after all the filtrate is collected, the diatomaceous earth coating is attached to the side of the filter screen close to the filter cartridge, and the support member supports the filter screen, effectively reducing the falling of the diatomaceous earth coating of the filter screen, and then pours the fermentation liquid into the filter cartridge and pressurizes it, so that the diatomaceous earth coating of the filter screen effectively filters the fermentation liquid; finally, pour out the wine with a predetermined capacity in advance with a measuring cup to reduce the influence of the falling of the diatomaceous earth coating on the turbidity during the pressurized filtration process, and then use another measuring cup to collect the predetermined capacity of wine for turbidity detection.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-3 This application is described in further detail.

[0043] The present application embodiment discloses a small filtering device for beer filtering. Figure 1 , including a filter cartridge 1 and a collecting bucket 2.

[0044] refer to Figure 1 and Figure 2 In this embodiment, the filter cartridge 1 may be a hollow cylinder, and openings are provided at the top and the bottom of the filter cartridge 1 .

[0045] The collecting hopper 2 includes a connecting portion 23 and a guide portion 24; in this embodiment, the guide portion 24 may be a substantially conical or quasi-conical funnel, and a plurality of brackets 243 are provided along the circumference of the outer wall of the guide portion 24, and the brackets 243 are arranged in a triangular shape to facilitate placing the collecting hopper 2 at a predetermined position, and an adjusting member is provided at the discharge port of the guide portion 24 to adjust the liquid to flow out of the collecting hopper 2. In this embodiment, the adjusting member may be a hand valve 242, which is arranged at the discharge port of the guide portion 24, and then the flow rate and outflow of the liquid are controlled by adjusting the hand valve 242.

[0046] In this embodiment, the connection part 23 can be a hollow cylinder, and both ends of the connection part 23 are provided with openings adapted to the bottom of the filter cartridge 1, and the cross-sectional area of ​​the bottom of the connection part 23 is consistent with the cross-sectional area of ​​the feed port of the flow guide part 24, and the bottom of the connection part 23 is fixedly connected to one end of the flow guide part 24 where the feed port is provided. In order to facilitate the connection between the collection hopper 2 and the filter cartridge 1, a thread can be provided on the inner wall of the connection part 23, so that the connection part 23 is threadedly connected to the bottom of the filter cartridge 1.

[0047] refer to Figure 2 and Figure 3A filter assembly is provided in the collecting hopper 2 for filtering the liquid flowing through. The filter assembly includes a filter screen 21 and a support member; wherein the filter screen 21 has a diatomaceous earth coating, and the support member is detachably installed in the collecting hopper 2 for supporting the filter screen 21. When the liquid flows through the filter screen 21, the diatomaceous earth coating of the filter screen 21 may fall off under the action of gravity, and the support member can effectively reduce the falling of the diatomaceous earth coating.

[0048] refer to Figure 3 In this embodiment, the support member can be a support plate 22 with a through hole 221. A substantially annular bearing plate 241 is fixed along the circumferential direction on the inner wall of the flow guide 24 near the feed port. Of course, the bearing plate 241 can also be an arc-shaped plate symmetrically arranged along the circumferential direction of the inner wall of the flow guide 24. Accordingly, the shape of the bearing plate 241 can be adaptively designed according to the specifications of the actual installation space. The above is only an exemplary description and does not limit the shape of the bearing plate 241. Place the support plate 22 on the bearing plate 241, and then place the filter screen 21 on the bearing plate 241. When the liquid flows through the filter screen 21, the support plate 22 supports the diatomaceous earth coating of the filter screen 21, so that the filter screen 21 can effectively filter the liquid.

[0049] In addition, considering that during the process of threaded connection between the connection part 23 and the bottom of the filter cartridge 1, the bottom of the filter cartridge 1 will press against the filter screen 21, and excessive external force may damage the filter screen 21; and the inner wall of the connection part 23 is provided with threads, which makes it inconvenient to disassemble the support plate 22 and the filter screen 21; therefore, a roughly annular load block 231 is fixed to the inner wall of the connection part 23 near one end of the guide part 24. Of course, the load block 231 can also be an arc-shaped block symmetrically arranged along the inner wall of the guide part 24. Accordingly, the shape of the bearing plate 241 can be adaptively designed according to the specifications of the actual installation space. The above is only an exemplary description and does not limit the shape of the load block 231.

[0050] refer to Figure 2 and Figure 3 The bottom of the load block 231 is fixedly connected to the bearing plate 241, and the width of the load block 231 is smaller than the width of the bearing plate 241. In addition, the inner wall of the load block 231 is a concave arc surface that matches the side wall of the filter screen 21. When the support plate 22 and the filter screen 21 are installed, the bottom of the support plate 22 abuts against the bearing plate 241, and the side walls of the support plate 22 and the filter screen 21 abut against the load block 231 respectively. In this embodiment, the mesh surface at the top of the filter screen 21 is flush with the top plane of the load block 231, and the aperture of the support plate 22 is larger than the aperture of the filter screen 21. After the liquid flows through the filter screen 21 for filtration, the support plate 22 allows the filtered liquid to pass quickly, thereby improving the filtration efficiency of the liquid.

[0051] At the same time, the plane at the top of the filter screen 21 is perpendicular to the axis of the filter cartridge 1, so that the filter screen 21 can filter the liquid flowing through it; further, the connecting portion 23 is threadedly connected to the filter cartridge 1, and the bottom of the filter cartridge 1 will abut against the top of the load block 231 and the top of the filter screen 21, thereby protecting the filter screen 21 and facilitating the disassembly of the support plate 22 and the filter screen 21.

[0052] An anti-impact component is detachably installed in the filter cartridge 1, which is used to buffer the liquid. When the liquid is poured into the filter cartridge 1 and flows through the filter screen 21, the possibility of washing away the diatomaceous earth layer of the filter screen 21 under the action of gravity is effectively reduced. In this embodiment, the anti-impact component includes a roughly conical funnel 11. In order to facilitate the placement of the funnel 11 in the filter cartridge 1, a bearing component is provided in the filter cartridge 1 for bearing the funnel 11; the bearing component includes a bearing block 12, which is roughly in an arc shape or an arc-like shape. At least two bearing blocks 12 that protrude inwardly are symmetrically arranged along the circumferential direction on the inner wall of the filter cartridge 1 near the bottom. Of course, the bearing block 12 can also be an annular block arranged along the circumferential direction of the inner wall of the filter cartridge 1. Accordingly, the shape of the bearing block 12 can be adaptively designed according to the specifications of the actual installation space. The above is only an exemplary description and does not limit the shape of the bearing block 12.

[0053] refer to Figure 3 In this embodiment, two bearing blocks 12 can be provided, and the arc length of the bearing block 12 is set to be one-fourth of the circumference of the feed end of the funnel 11. The bottom of the bearing block 12 abuts against the top of the filter screen 21, which can reduce the possibility that the filter screen 21 is difficult to effectively filter the liquid due to shaking. The funnel 11 is placed upside down on the bearing block 12, and one end of the feed port of the funnel 11 abuts against the top of the filter screen 21. The funnel 11 is located just above the filter screen 21, and the liquid will flow along the outer wall of the funnel 11 to the filter screen 21. In order to facilitate the rapid passage of the liquid through the funnel 11, a plurality of guide holes 111 can be opened along the circumferential direction on the outer wall of the funnel 11 near the feed port, and the bearing block 12 also has a plurality of guide holes 111 along the arc length direction; the liquid is poured into the filter cartridge 1, and the liquid flows along the outer wall of the funnel 11 through the guide holes 111 to the filter screen 21, thereby achieving an effective buffering effect on the liquid.

[0054] refer to Figure 2 and Figure 3In order to speed up the efficiency of liquid passing through the filter screen 21, a top cover 3 may be provided on the top of the filter cartridge 1, and the top cover 3 is threadedly connected to the filter cartridge 1. A pressurizing component is provided on the top of the top cover 3 to speed up the liquid flowing through the filter screen 21 and the support plate 22. In this embodiment, the pressurizing component includes an air pipe joint 31 connected to a pressure regulating device, and the air pipe joint 31 is connected to the filter cartridge 1. In actual operation, after pouring liquid into the filter cartridge 1, the funnel 11 is taken out, and then the top cover 3 is closed, and then pressure filtration is performed through the air pipe joint 31, thereby achieving the effect of speeding up the filtration of liquid by the filter screen 21.

[0055] The implementation principle of a small filtering device for beer filtering in the embodiment of the present application is as follows: first, the support plate 22 is placed on the bearing plate 241, and the side wall of the support plate 22 abuts against the load block 231, and then the filter screen 21 is placed on the top of the support plate 22, and the side wall of the filter screen 21 abuts against the load block 231 at the same time, and the top plane of the filter screen 21 is flush with the top plane of the load block 231; further, the connecting portion 23 of the collecting bucket 2 is threadedly connected to the bottom of the filter cartridge 1, and the bottom of the filter cartridge 1 abuts against the load block 231 and the top of the filter screen 21, and the bearing block 12 abuts against the top of the filter screen 21 , effectively limiting the shaking of the filter screen 21; further, the funnel 11 is placed upside down in the filter cartridge 1, and the end of the funnel 11 close to the feed hopper abuts against the supporting block 12, and the liquid is further poured into the filter cartridge 1, and the liquid flows along the outer wall of the funnel 11 and further flows to the filter screen 21 through the guide hole 111, so that the funnel 11 plays a buffering role for the liquid; then, the funnel 11 is taken out, the top cover 3 is tightened, and then air pressure is introduced into the air pipe joint 31 through the pressure regulating device, and the liquid will accelerate through the filter screen 21 and the support plate 22; finally, the outflow and flow of the liquid are controlled by the hand valve 242, and then the liquid is tested.

[0056] The present application also discloses a filtration method for beer filtration, which can be implemented by the above-mentioned filtration device, comprising the following steps:

[0057] Step 1: Prepare the pre-coating liquid, calculate the pre-coating amount of diatomaceous earth per unit area according to the actual pre-coating formula, and add various types of diatomaceous earth according to the actual proportion. Pour a certain amount of diatomaceous earth into a predetermined amount of tap water and stir evenly; in this embodiment, the pre-coating amount of diatomaceous earth per unit area is selected as 50cm² pre-coating amount; the predetermined amount of tap water can be selected as 1L pre-coating amount.

[0058] Step 2: pre-coating under pressure, pour the pre-coating liquid into the filter cartridge 1, tighten the top cover 3, and only pre-coat under pressure according to the preset value. In this embodiment, according to the pre-coating amount of diatomaceous earth in the first step, the preset pressure value can be 4 bar; Figure 3 By utilizing a predetermined pressure value, the filter screen 21 can quickly form a relatively compact diatomaceous earth layer, which is more suitable for the high-flow pre-coating step in actual production.

[0059] refer to Figure 2 and Figure 3 , adjust the hand valve 242 and collect the filtrate with a measuring cup at the outlet of the collecting hopper 2. After collecting all the filtrate, put it into the funnel 11, and pour the filtered pre-coating liquid back into the filter cartridge 1. The filtrate will flow along the outer wall of the funnel 11 and through the guide port of the funnel 11 to the filter screen 21. The funnel 11 can effectively reduce the impact of the filtrate on the diatomaceous earth coating formed by the first filter screen 21. Theoretically, the filter screen 21 should be pre-coated at least twice, depending on the clarity of the actual filtrate; this step achieves the effect of making the diatomaceous earth coating uniform.

[0060] The third step is to prepare the fermentation liquid, calculate the amount of diatomaceous earth required for the predetermined amount of fermentation liquid according to the actual process addition amount and filtration flow rate, add a certain amount of diatomaceous earth to the fermentation liquid, and stir evenly; in this embodiment, 500 ml of fermentation liquid can be selected, and then the required amount of diatomaceous earth is calculated.

[0061] Step 4: Pressure filtration; reference Figure 2 , first put in the funnel 11, then slowly pour in the fermentation liquid within a predetermined time. The funnel 11 can effectively reduce the possibility of the fermentation liquid damaging the diatomaceous earth coating during the pouring process; then, after adding, gently take out the funnel 11, cover the top cover 3 and filter according to the predetermined value under pressure; wherein, the predetermined time ranges from 20 to 30 seconds, and the predetermined pressure ranges from 2 to 2.5 bar. In this embodiment, the predetermined time can be 25 seconds, and the predetermined pressure value is 2 bar for filtration. When pressurized, the fermentation liquid will quickly pass through the filter 21, thereby improving the operating efficiency.

[0062] Step 5: Sampling and testing; first collect a predetermined volume of wine with a measuring cup and pour it out, and then use another measuring cup to take the remaining predetermined volume of wine to test the turbidity; in this step, two measuring cups need to be prepared to effectively reduce the interference of the front and rear measuring cups; because the turbidity of the early wine will be affected by the pressure filtration in the previous fourth step, the wine with the predetermined volume of the early filtration should be discarded. In this embodiment, according to the above steps, 100 ml of the early wine can be discarded with a measuring cup; then use another measuring cup to take the remaining predetermined volume of wine, and 400 ml of wine can be selected for turbidity testing, thereby achieving the effect of improving the accuracy of wine turbidity detection.

[0063] 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.
