Description

Technical Field

[0001] This utility model relates to the field of flavonoid extraction technology, and in particular to a flavonoid extraction device. Background Technology

[0002] Flavonoids are a class of natural compounds widely found in plants. They belong to the polyphenol class and have a variety of biological activities, showing significant effects in anti-oxidation, anti-inflammation, anti-cancer, and cardiovascular protection.

[0003] Water extraction is a common method for extracting flavonoids. Specifically, the raw material is placed in water, heated, and stirred to allow the flavonoids to diffuse from the cells of the raw material into the water. After diffusion, the raw material needs to be filtered through a screen to separate the residue from the solution. In related technologies, the screen is located inside the extraction tank; however, when the screen becomes clogged, it is difficult to remove and clean. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a flavonoid extraction device with an easy-to-clean filter screen.

[0005] A flavonoid extraction device according to some embodiments of the present invention includes: an extraction tank with a discharge pipe; a filter assembly including an outer cavity, a filter screen, and a fastener; the outer cavity having an installation cavity with a disassembly port and an installation hole communicating with the installation cavity, the installation hole for the discharge pipe to pass through; the cavity wall of the installation cavity forming a support platform facing the disassembly port; the filter screen being detachably disposed in the installation cavity and disposed opposite to the discharge pipe; the fastener including a support portion extending into the installation cavity and a fastening portion connected to the support portion; the filter screen being pressed by the support portion and abutting against the support platform; and the fastening portion being detachably fastened to the outer cavity.

[0006] The flavonoid extraction device according to the embodiments of this utility model has at least the following beneficial effects:

[0007] In this flavonoid extraction device, the discharge pipe passes through the mounting hole of the outer cavity, allowing the internal flow channel of the discharge pipe to communicate with the mounting cavity of the outer cavity. Thus, during the discharge process, the residue in the extraction tank is blocked by a filter screen located within the mounting cavity, while the liquid is discharged through the filter screen. Furthermore, because the support portion of the fastener supports the filter screen away from the discharge pipe, the supporting force of the support portion on the filter screen can offset the impact force of the residue and liquid on the filter screen, reducing the risk of the filter screen falling off. Simultaneously, the filter screen is pressed against the support platform by the support portion, which can limit the position of the filter screen and improve its stability. When the filter needs to be cleaned, the fastener can be detached from the outer cavity, separating the entire fastener from the outer cavity. Then, the filter can be removed through the mounting port for cleaning. Afterward, the cleaned filter can be reinstalled into the mounting cavity through the mounting port, and then the fastener can be fastened back onto the outer cavity to support the filter. The entire filter replacement process is very convenient.

[0009] According to some embodiments of the present invention, the fastener further includes a positioning part connected to the support part, and the outer cavity has a positioning end face surrounding the mounting / dismounting port, wherein the positioning part is positioned and engaged with the positioning end face.

[0010] According to some embodiments of the present invention, the outer cavity has a fastening wall disposed opposite to the mounting / dismounting port, the fastening part is connected to the positioning part, and the fastening part is upside down on the fastening wall.

[0011] According to some embodiments of the present invention, the fastening part includes an elastic connecting part connected to the positioning part and an undercut part connected to the elastic connecting part. The elastic connecting part is located on the outside of the outer cavity, and the undercut part is undercut against the fastening wall. The elastic connecting part is configured to be able to be deflected away from the outer cavity under force so that the fastening part is disengaged from the fastening wall.

[0012] According to some embodiments of the present invention, the filter assembly further includes a material agitator, which is movably disposed within the mounting cavity and located on the side of the filter screen near the discharge pipe.

[0013] According to some embodiments of the present invention, the slag agitator is rotatably connected to the outer cavity; the filter assembly further includes a swing drive mechanism disposed in the mounting cavity and used to drive the slag agitator to swing.

[0014] According to some embodiments of the present invention, the swing drive mechanism includes the rotary drive component and a turntable driven and connected to the rotary drive component. The turntable is provided with drive rods that are parallel to and spaced apart from the rotation axis of the turntable. The slag agitator is provided with a guide groove extending along its axial direction, and the drive rods pass through the guide groove.

[0015] According to some embodiments of this utility model, the wall of the mounting hole is provided with an internal thread, and the outer wall of the discharge pipe is provided with an external thread, wherein the external thread is connected to the internal thread.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1 As shown in the figure, an embodiment of the present invention provides a flavonoid extraction device that can extract flavonoids from raw materials, such as corn silk, ginkgo leaves, and scutellaria baicalensis.

[0036] It should be noted that after flavonoids are extracted, they can be used as raw materials for some edible products. For example, flavonoids extracted from corn silk can be used as raw materials for coffee products.

[0037] The flavonoid extraction equipment includes an extraction tank 100 and a filter assembly 300.

[0038] The extraction tank 100 is a hollow tank-shaped structure used to load raw materials and water. It should be noted that the flavonoid extraction equipment also includes a stirring mechanism 200, which is used to stir the substances in the extraction tank 100, thereby improving the extraction efficiency of flavonoids.

[0039] Specifically, the stirring mechanism 200 includes a drive source 210 and a stirring element 220 that is driven and connected to the drive source 210. The stirring element 220 is disposed inside the extraction tank 100. The drive source 210 is used to drive the stirring element 220 to rotate, thereby stirring the material inside the extraction tank 100.

[0040] The driving source 210 can be an electric motor, and the stirring element 220 is connected to the drive shaft of the electric motor. The electric motor is located at the top of the extraction tank 100, and the stirring element 220 extends into the interior of the extraction tank 100.

[0041] Furthermore, the top of the extraction tank 100 is provided with a raw material inlet, through which raw materials can be poured into the extraction tank 100.

[0042] Furthermore, the extraction tank 100 is equipped with a discharge pipe 110, the internal flow channel of which is connected to the internal space of the extraction tank 100, and the filter assembly 300 is installed on the discharge pipe 110. After the flavonoids in the raw material have diffused into the water, the residue is blocked by the filter assembly 300, while the liquid containing flavonoids can be discharged through the discharge pipe 110 for collection.

[0043] It is understandable that a valve 120 is installed on the discharge pipe 110 to control the opening and closing of the discharge pipe 110. When the valve 120 is in the closed state, the discharge pipe 110 is blocked by the valve 120. When the valve 120 is in the open state, the liquid in the extraction tank 100 can be discharged through the discharge pipe 110.

[0044] In some embodiments, the discharge pipe 110 is located at the bottom of the extraction tank 100. When the valve 120 is opened, the liquid in the extraction tank 100 can be discharged directly under gravity. Of course, in other embodiments, the discharge pipe 110 can also be located at other parts of the extraction tank 100. For example, the discharge pipe 110 can be located on the side of the extraction tank 100, and the discharge pipe 110 is connected to a conduit located inside the extraction tank 100. The end of the conduit away from the discharge pipe 110 extends to the bottom of the extraction tank 100, and the liquid in the extraction tank 100 can be drawn out by means of a water pump.

[0045] like Figures 2 to 4 As shown, the filter assembly 300 includes an outer cavity 310, a filter screen 320, and a fastener 330. The outer cavity 310 is provided with a mounting cavity 311 having a mounting opening 313 and a mounting hole 312 communicating with the mounting cavity 311. The mounting hole 312 allows the discharge pipe 110 to pass through. The filter screen 320 is detachably disposed in the mounting cavity 311 and is disposed opposite to the discharge pipe 110. The fastener 330 includes a support portion 331 extending into the mounting cavity 311 and a fastening portion 333 connected to the support portion 331. The support portion 331 supports the side of the filter screen 320 away from the discharge pipe 110, and the fastening portion 333 is detachably fastened to the outer cavity 310.

[0046] Specifically, the outer cavity 310 includes a main body 310a and a sleeve 310b connected to the main body 310a. The sleeve 310b is provided with a mounting hole 312. The main body 310a is provided with a mounting cavity 311 communicating with the mounting hole 312. The discharge pipe 110 passes through the mounting hole 312 and is sleeved by the sleeve 310b.

[0047] Understandably, the discharge pipe 110 passes through the mounting hole 312 of the outer cavity 310, allowing the internal flow channel of the discharge pipe 110 to communicate with the mounting cavity 311 of the outer cavity 310. Thus, during the discharge process, the slag in the extraction tank 100 is blocked by the filter screen 320 located within the mounting cavity 311 after entering it, while the liquid is discharged through the filter screen 320. Furthermore, since the support portion 331 of the fastener 330 supports the side of the filter screen 320 away from the discharge pipe 110, the supporting force of the support portion 331 on the filter screen 320 can offset the impact force of the slag and liquid on the filter screen 320, reducing the risk of the filter screen 320 falling off. When the filter screen 320 needs to be cleaned, the fastening part 333 can be detached from the outer cavity 310, so that the entire fastening part 330 is separated from the outer cavity 310. Then, the filter screen 320 can be taken out through the installation and removal port 313 for cleaning. After that, the cleaned filter screen 320 can be reinstalled into the mounting cavity 311 through the installation and removal port 313. Then, the fastening part 330 is fastened on the outer cavity 310 so that the support part 331 supports the filter screen 320. The whole process of replacing the filter screen 320 is very convenient.

[0048] It should be noted that the mounting port 313 is positioned opposite to the mounting hole 312; in other words, the mounting port 313 is positioned opposite to the discharge pipe 110. After the fastener 330 is removed from the outer cavity 310, the filter screen 320 can be directly poured out from the mounting port 313, which is simple to operate.

[0049] like Figure 4 As shown, the cavity wall of the mounting cavity 311 is further formed with a support platform 316 facing the mounting / removal port 313, and the filter screen 320 is pressed by the support part 331 and abuts against the support platform 316. In this way, the filter screen 320 can be fixed by the combined clamping action of the support platform 316 and the support part 331.

[0050] In some embodiments, the fastener 330 further includes a positioning part 332 connected to the support part 331, and the outer cavity 310 has a positioning end face 315 disposed around the mounting and dismounting port 313, with the positioning part 332 and the positioning end face 315 being positioned and engaged.

[0051] Specifically, the socket portion 310b is disposed at one end of the main body portion 310a, the mounting and disassembly port 313 is formed at the end of the main body portion 310a away from the socket portion 310b, and the positioning end face 315 is also located at the end of the main body portion 310a away from the socket portion 310b and is disposed around the mounting and disassembly port 313. The support portion 331 extends into the mounting cavity 311 through the mounting and disassembly port 313, and the positioning portion 332 fits against the positioning end face 315. The positioning end face 315 can limit the positioning portion 332, thereby positioning the entire fastener 330.

[0052] Furthermore, the outer cavity 310 has a fastening wall 314 disposed opposite to the mounting / dismounting port 313; specifically, the fastening wall 314 is the wall surface of the main body 310a near the sleeve portion 310b. The fastening portion 333 is connected to the positioning portion 332, and the fastening portion 333 is snapped onto the fastening wall 314.

[0053] It is understandable that after the fastening part 333 is fastened to the fastening wall 314, the fastening part 330 is limited relative to the outer cavity 310 in the axial direction of the discharge pipe 110, so that the support part 331 maintains the state of supporting the filter screen 320.

[0054] Furthermore, the fastening part 333 includes an elastic connecting part 3331 connected to the positioning part 332 and a buckling part 3332 connected to the elastic connecting part 3331. The elastic connecting part 3331 is located on the outside of the outer cavity 310, and the buckling part 3332 is buckled against the fastening wall 314. The elastic connecting part 3331 is configured to be able to be deflected away from the outer cavity 310 under force so that the fastening part 333 disengages from the fastening wall 314.

[0055] Understandably, the elastic connecting part 3331 is elastic. The operator can apply force to the elastic connecting part 3331 to make it deflect away from the outer cavity 310, thereby causing the fastening part 333 to disengage from the fastening wall 314, and thus the entire fastening part 330 to be removed from the outer cavity 310. When the external force applied to the elastic connecting part 3331 disappears, the elastic connecting part 3331 automatically resets.

[0056] Understandably, the entire fastener 330 can be made of elastic steel, and the elastic connecting part 3331 is strip-shaped and easily deformable.

[0057] Furthermore, there are multiple fastening parts 333, which are spaced apart around the positioning part 332. The multiple fastening parts 333 can be fastened together with the outer cavity 310, thereby improving stability.

[0058] Combination Figure 4 and Figure 5 In some embodiments, the filter assembly 300 further includes a slag agitator 340, which is movably disposed in the mounting cavity 311 and located on the side of the filter screen 320 near the discharge pipe 110.

[0059] It should be noted that when valve 120 is opened, the sludge will be discharged into the installation cavity 311 through discharge pipe 110 and blocked by filter screen 320. However, a large amount of filter sludge will accumulate directly below discharge pipe 110. When these sludge accumulate together, the gaps between them will decrease due to gravity, affecting the discharge of liquid and clogging parts of the filter screen, thereby reducing the liquid discharge rate. The sludge agitator 340 can agitate the sludge in the installation cavity 311, thereby improving the problem of too small gaps between the sludge and making the sludge more evenly distributed in all parts of filter screen 320, reducing the risk of local clogging of filter screen 320 and improving the problem of slow liquid discharge rate.

[0060] Combination Figure 5 and Figure 6 In some other embodiments, the slag agitator 340 is integrally disposed within the mounting cavity 311, and the slag agitator 340 is rotatably connected to the outer cavity 310. Specifically, the slag agitator 340 has a rod-shaped structure, one end of which is rotatably connected to the connector 350. Furthermore, the filter assembly 300 also includes a swing drive mechanism 360 disposed within the mounting cavity 311 and used to drive the slag agitator 340 to swing.

[0061] Understandably, the oscillating drive mechanism 360 can drive the slag agitator 340 to oscillate, thereby agitating the slag in the mounting cavity 311.

[0062] Specifically, the oscillating drive mechanism 360 includes a rotary drive component 361 and a turntable 362 drivenly connected to the rotary drive component 361. The rotary drive component 361 drives the turntable 362 to rotate. The rotary drive component 361 can be a motor, and it drives the turntable 362 to rotate around its axis. The turntable 362 is provided with drive rods 363 parallel to and spaced apart from its axis (rotation axis). The slag agitator 340 has a guide groove 341 extending axially, and the drive rods 363 pass through the guide groove 341. When the rotary drive component 361 drives the turntable 362 to rotate, it can drive the slag agitator 340 to oscillate back and forth with the help of the drive rods 363, thereby agitating the slag in the mounting cavity 311. It is understood that in this embodiment, when the swing drive mechanism 360 drives the material agitator 340 to agitate the material residue in the mounting cavity 311, the valve 120 does not need to be closed. This can be performed during the filtration of the extract, which can improve the problem of the filtration efficiency being affected by closing the valve 120.

[0063] like Figure 2As shown, in some embodiments, the outer cavity 310 is detachably connected to the discharge pipe 110. Specifically, the wall of the mounting hole 312 is provided with internal threads, and the outer wall of the discharge pipe 110 is provided with external threads, which are connected to the internal threads. This facilitates the replacement of the entire filter assembly 300. In addition, when it is necessary to clean or replace the filter screen 320, the entire filter assembly 300 can be disassembled first, and then the filter screen 320 on the filter assembly 300 can be disassembled, which is more convenient.

[0064] like Figure 1 As shown, it should be noted that the flavonoid extraction equipment also includes an oil storage sleeve 400 fitted onto the extraction tank 100. An oil storage space 410 is formed between the oil storage sleeve 400 and the extraction tank 100. A heating element 500 is installed in the oil storage space 410. The heating element 500 can be a heating rod or a heating wire.

[0065] Understandably, edible oil can be injected into the oil storage space 410, and the heating element 500 can heat the edible oil. The temperature of the heated edible oil is more uniform throughout, which can improve the heating uniformity of the relevant substances in the extraction tank 100 and improve the extraction effect of flavonoids.

[0066] Furthermore, the oil storage sleeve 400 is provided with an oil inlet communicating with the oil storage space 410 and an exhaust port communicating with the oil storage space 410. Oil can be injected into the oil storage space 410 through the oil inlet, and during the oil injection process, the gas in the oil storage space 410 can be discharged through the exhaust port.

[0067] It should be noted that an exhaust pipe 420 connected to the external environment can be connected to the exhaust port of the oil storage sleeve 400 so that the gas in the oil storage space 410 can be discharged.

[0068] In some embodiments, the flavonoid extraction device further includes a heat insulation sleeve 600 fitted over the oil storage sleeve 400, with a heat insulation space 610 formed between the heat insulation sleeve 600 and the oil storage sleeve 400 to provide heat insulation and reduce the risk of workers being burned by touching the device.

[0069] The specific process for extracting flavonoids using the flavonoid extraction equipment of this invention is as follows:

[0070] (1) Pre-treat the raw materials (such as corn silk), specifically by drying and crushing the raw materials;

[0071] (2) Add the liquid to the extraction tank 100 at a ratio of 1:15 (e.g., 100g raw material + 1.5L water);

[0072] (3) Add edible oil to the oil storage space 410 and make the edible oil level higher than the substance in the extraction tank 100. Then start the heating element 500 to keep the temperature of the edible oil at 95℃-100℃. Then start the stirring mechanism 200 to stir the substance in the extraction tank 100.

[0073] (4) Open valve 120 and collect the discharged liquid.

[0074] It should be noted that the above only describes the steps of the flavonoid extraction equipment of this utility model in extracting flavonoids. After collecting the liquid extracted by the flavonoid extraction equipment, there are also steps including but not limited to further purification and drying of the liquid. Furthermore, the dried corn silk flavonoid extract can be mixed with coffee powder and pear cactus juice powder to prepare an anti-edema coffee composition.

[0075] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0076] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
