Description

Technical Field

[0001] This utility model relates to the field of filter tank technology, specifically a structure for a craft beer mashing filter tank. Background Technology

[0002] Beer is brewed primarily from wheat malt and barley malt, with the addition of hops, through liquid gelatinization and saccharification, followed by liquid fermentation. The main brewing process involves mixing crushed malt and starchy adjuncts with warm water in a mashing vessel, adjusting the temperature. After filtering the wort through a filter tank, it is boiled in a boiling kettle, hops are added, and the wort concentration is adjusted to the appropriate level. The wort is then transferred to a vortex settling tank to separate the hot coagulated material. The clarified wort is then cooled to 5–8°C in a cooler. A common brewery filter tank is a cylindrical container with perforated sieves; rotating blades filter the wort.

[0003] For example, patent publication number CN211896875U discloses a filter tank, including a support device, a tank body mounted on the support device, the tank body including a cylindrical side wall and a top cover connected to the top of the side wall, a circular manhole on the top cover, a liquid inlet on the side wall, a cleaning device inside the tank body, the cleaning device including an upper washing pipe penetrating the top cover vertically, a coil connected to the bottom of the washing pipe, and several rotating washing balls evenly arranged at the bottom of the coil, a stirring device inside the tank body, and a filtering device at the bottom of the tank body, the filtering device including a filtering mechanism located below the stirring device, a liquid collecting bottom located below the filtering mechanism and protruding downward at the center, a slag discharge pipe located at the center of the bottom of the liquid collecting bottom, several leakage holes evenly distributed around the liquid collecting bottom, a leakage pipe located below the leakage holes, an annular pipe located at the bottom of the leakage pipe, and a liquid outlet on the annular pipe.

[0004] While the aforementioned device solves the problem of easy cleaning, it still has the following drawbacks: After filtration, the chaff is discharged through a side outlet on one side of the filter tank. However, the discharged chaff still carries a significant amount of wort. Since the chaff can be recycled as a byproduct, the accompanying wort increases the weight of subsequent collections, causing inconvenience for transportation and processing, and also resulting in material waste. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a craft beer mashing and filtration tank structure, so that the chaff can be filtered by pressure after being discharged from the lees outlet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a craft beer mashing and filtration tank structure, comprising a filter tank body, a slag discharge port connected to the outer wall of the filter tank body, and a guide plate connected to the bottom of the slag discharge port. A filter press is connected below the slag discharge port. A rotating shaft is rotatably connected inside the filter press. A rotary motor is fixedly installed on the outer wall of the filter press. The output end of the rotary motor is fixedly installed to one end of the rotating shaft. Four equidistant rotating plates are fixedly connected to the outer side of the rotating shaft. A permeation plate for liquid permeation is fixedly connected inside the filter press. An opening for liquid guidance is provided on the bottom surface of the filter press. A slag discharge port for slag guidance is provided at the outer end of the filter press. An extrusion component is provided inside the filter press.

[0007] Furthermore, the extrusion component includes a pressure plate, and a movable pressure plate is provided inside the filter press. The pressure plate is located on the top surface of the permeation plate and is slidably connected to it. A second electric push rod is fixedly installed on the inner wall of the filter press. The second electric push rod is fixedly connected to the pressure plate and is located on the side away from the rotating plate.

[0008] Furthermore, a liquid guiding hopper for guiding liquid is fixedly installed at the bottom opening of the filter press, and the liquid guiding hopper is connected to the storage device through an external pipe.

[0009] Furthermore, a baffle is slidably connected to the top surface of the filter press, and a first electric push rod is fixedly connected to the top surface of the filter press. The output end of the first electric push rod is fixedly installed with the baffle, and the first electric push rod is located at the end away from the baffle.

[0010] Furthermore, a filter screen is fixedly connected inside the filter press, and the filter screen is located between the permeation plate and the liquid guide hopper.

[0011] Furthermore, the bottom surface of the filter press box is fixedly connected with two sets of supports for support.

[0012] Furthermore, the bottom surface of the outlet at the outer end of the filter press is inclined.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes the synergistic action of a pressure plate, a permeation plate, and multiple rotating plates to allow wheat husks to fall from a guide plate into the area between the permeation plate and two rotating plates. Under the pressure of the pressure plate, the wheat husks are compressed into a cake shape, while the wort is discharged through the permeation plate and the bottom of the filter press, thus achieving wort recovery. The compressed wheat husk cake is smoothly rotated out by the rotation of the rotating plates, achieving continuous and automatic slag discharge. This structure not only effectively reduces wort residue in the wheat husk residue and lightens the subsequent collection weight, but also facilitates continuous operation of cake pressing and slag discharge. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a craft beer mashing and filtration tank structure includes a filter tank body 1, a slag discharge port 2 connected to the outer wall of the filter tank body 1, and a guide plate 3 connected to the bottom of the slag discharge port 2. A filter press box 4 is connected below the slag discharge port 2. A rotating shaft 15 is rotatably connected inside the filter press box 4. A rotary motor 6 is fixedly installed on the outer wall of the filter press box 4. The output end of the rotary motor 6 is fixedly installed at one end of the rotating shaft 15. Four equidistant rotating plates 5 are fixedly connected to the outer side of the rotating shaft 15. A permeation plate 12 for liquid permeation is fixedly connected inside the filter press box 4. An opening for liquid guidance is opened on the bottom surface of the filter press box 4. A slag discharge port for slag guidance is opened at the outer end of the filter press box 4. An extrusion component is provided inside the filter press box 4.

[0023] like Figure 1 As shown, the structure of the craft beer mashing filter tank in this utility model is similar to that of existing filter tanks, such as the filter tank disclosed in patent publication number CN211896875U. The main improvement of this utility model is that the chaff can be pressure filtered after being discharged from the lees outlet, such as... Figures 1 to 5As shown, in the craft beer saccharification and filtration tank structure of this utility model, when in use, the slag discharge port 2 is opened, allowing the chaff to move and slide down on the inclined guide plate 3, falling into the bottom filter press 4, and landing on the rotating plate 5 and the permeation plate 12. At this time, the extruder is activated to extrude the chaff in the right-angle area formed between the permeation plate 12 and the two rotating plates 5 on the filter press 4, forming a filter cake. After filtration to a certain extent (e.g., determined by time), the extruder retracts, the rotary motor 6 rotates, driving the rotating shaft 15 to rotate, driving the rotating plate 5 to rotate, causing the rotating plate 5 to rotate 90 degrees, turning out the area between the two rotating plates 5 without chaff, while the area carrying the chaff filter cake rotates outward to the discharge port at the outer end of the filter press 4 for discharge. In actual application, a mesh can also be set on the rotating plate 5 for liquid discharge during the extrusion process.

[0024] like Figure 2 and Figure 4 As shown, the extrusion component includes a pressure plate 10. The filter press 4 is equipped with a movable pressure plate 10. The pressure plate 10 is located on the top surface of the permeation plate 12 and is slidably connected to it. A second electric push rod 11 is fixedly installed on the inner wall of the filter press 4. The second electric push rod 11 is fixedly connected to the pressure plate 10 and is located on the side away from the rotating plate 5.

[0025] Specifically, when the wheat husks fall into the right-angled area formed between the permeation plate 12 and the two rotating plates 5, the second electric push rod 11 is activated, driving the pressure plate 10 to move. The pressure plate 10 squeezes the wheat husks until they are pressed against the rotating plates 5, making the wheat husks into a cake shape. Under the self-locking of the rotary motor 6, the rotating plates 5 can remain stable and will not rotate when the pressure plate 10 is pressing them.

[0026] The filter press 4, pressure plate 10, permeation plate 12, and multiple rotating plates 5 allow the wheat husks to fall from the guide plate 3 into the area between the permeation plate 12 and the two rotating plates 5. As the pressure plate 10 presses, the wheat husks are squeezed into a cake shape in the rotating plates 5, while the wort permeates and is discharged from the bottom of the filter press 4. This allows the wort in the wheat husk residue to be filtered out, making it convenient for the later collection of the wheat husk residue. The rotating plates 5 can smoothly discharge the wheat husk cake, facilitating continuous husk pressing.

[0027] like Figure 2 As shown, a liquid guide hopper 14 for guiding liquid is fixedly installed at the bottom opening of the filter press 4. The liquid guide hopper 14 is connected to a storage device through an external pipe. The liquid guide hopper 14 facilitates the collection of the filtered wort, while the external storage device can be used according to the actual application, such as a storage tank.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, a baffle 8 is slidably connected to the top surface of the filter press 4, and a first electric push rod 9 is fixedly connected to the top surface of the filter press 4. The output end of the first electric push rod 9 is fixedly installed with the baffle 8, and the first electric push rod 9 is located at the end away from the baffle 8.

[0029] Specifically, when the wheat husk residue is discharged, the first electric actuator 9 is activated, driving the baffle 8 to retract and move away from the guide plate 3. This ensures that the wheat husks on the guide plate 3 fall smoothly. In the retracted state, the baffle 8 is always positioned in front of the vertical rotating plate 5. This ensures that the falling wheat husks, guided by the baffle 8, do not fall directly onto the outside of the vertical rotating plate 5, causing the wheat husk residue to spill out. In other words, when the baffle 8 is in the retracted position, it can still ensure that the wheat husks fall into the right-angle area formed by the permeation plate 12 and the two rotating plates 5. Thus, the baffle 8 also has the function of guiding and restricting the falling area.

[0030] Then the first electric push rod 9 resets, causing the baffle 8 to move forward and block the guide plate 3, preventing the wheat husks from falling off the guide plate 3. This setting ensures that the wheat husks on the guide plate 3 will not fall off and affect the extrusion process during the extrusion process. Then the pressure plate 10 pushes to perform the extrusion work until the rotary motor 6 rotates and discharges the extruded wheat husks into a cake shape. After that, the baffle 8 retracts and opens again, and the extrusion work is repeated.

[0031] like Figure 2 As shown, a filter screen 13 is also fixedly connected inside the filter press 4, and the filter screen 13 is located between the permeation plate 12 and the liquid guide hopper 14. The filter screen 13 allows for further filtration of the wort.

[0032] like Figure 1 and Figure 2 As shown, two sets of supports 7 are fixedly connected to the bottom surface of the filter press 4 for support. The supports 7 facilitate the support of the filter press 4.

[0033] like Figure 1 and Figure 2 As shown, the bottom surface of the discharge port at the outer end of the filter press 4 is inclined. This design ensures that the filter cake is discharged smoothly.

[0034] In the above structure, the first electric actuator 9, the second electric actuator 11, and the rotary motor 6 are all existing technologies. The rotary motor 6 should have a self-locking function to ensure the stability of the pressure plate 10 when it is under pressure.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
