Description

Technical Field

[0001] The present invention relates to the technical field of red clover processing, and in particular to a red clover production and processing device. Background Art

[0002] A variety of active ingredients such as isoflavones can be extracted from Trifolium pratense L. var. minus Kitag. Generally, the dried red clover material is first crushed, and an extractant such as water or alcohol is added for preliminary extraction to obtain an extract and extraction residue. Then, relevant process operations such as concentration and further extraction are carried out on the extract and extraction residue respectively, and finally isoflavones and the like are obtained.

[0003] When the crushed red clover material comes into contact with the extractant, the extraction effect is generally ensured by long-term stirring. However, during stirring, the material has strong fluidity but weak dispersion in the extractant. Moreover, due to different degrees of crushing, the contact effect between the material and the extractant is also different, resulting in the need to extend the stirring time to improve the extraction rate of the active ingredients inside the material. When the amount of the component extracted in the first step is small, it will seriously affect the output of the subsequent process operations. In the existing preliminary extraction process, the dispersion of the material in the extractant is weak, the contact effect is poor, and the problem affecting the extraction effect needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is, in view of the above-mentioned existing technical deficiencies, to provide a red clover production and processing device, which solves the problem that in the prior art, the dispersion of the material in the extractant is weak, affecting the extraction effect.

[0005] The technical solution adopted by the present invention is: to provide a red clover production and processing device for processing the crushed red clover. It is characterized in that it includes:

[0006] A mixing box for containing the extractant;

[0007] An outer cylinder is arranged at the lower end of the mixing box and is communicated with the mixing box;

[0008] A support net is arranged at the upper end of the outer cylinder, and the support net has a plurality of material leakage holes;

[0009] An inner cylinder is arranged to move up and down relative to the outer cylinder. The upper part of the inner cylinder is slidably sealed with the inner wall of the outer cylinder. The upper end of the inner cylinder has a sieve mesh. The sieve mesh and the support net are arranged to move relative to each other. The space between the sieve mesh and the support net is used to accommodate the material. After the inner cylinder moves close to the support net, the material enters the mixing box through the material leakage holes.

[0010] To further optimize the technical solution, the support net is rotatably arranged at the upper end of the outer cylinder.

[0011] To further optimize this technical solution, it further includes:

[0012] A sealing plug, which is slidably and sealingly arranged inside the inner cylinder. The sealing plug moves closer to or away from the screen after sliding. The space between the sealing plug and the screen is used to accommodate the extractant that seeps down from the materials above the screen.

[0013] To further optimize this technical solution, at least one liquid discharge hole is annularly provided on the circumferential side wall of the inner cylinder. When the sealing plug moves away from the screen and moves below the liquid discharge hole, the liquid discharge hole communicates with the space between the sealing plug and the screen. A water receiving pool is also provided on the outer periphery of the lower part of the inner cylinder. The extractant between the sealing plug and the screen is discharged from the liquid discharge hole into the water receiving pool.

[0014] To further optimize this technical solution, a sealing part is provided on the outer periphery of the upper part of the inner cylinder. The sealing part is slidably and sealingly arranged on the inner wall of the outer cylinder, and there is a gap between the outer wall of the inner cylinder and the inner wall of the outer cylinder.

[0015] To further optimize this technical solution, it further includes:

[0016] A first linear driving mechanism for driving the relative lifting of the outer cylinder and the inner cylinder.

[0017] To further optimize this technical solution, it further includes:

[0018] A second linear driving mechanism is arranged at the lower end inside the inner cylinder and is used to drive the sealing plug to slide inside the inner cylinder.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The crushed red clover materials are between the screen and the support screen. Through the relative movement and extrusion of the screen and the support screen, the materials are extruded upward from the leakage holes of the support screen. Through extrusion and passing through the leakage holes, the materials are further damaged, the contact area between the materials and the extractant in the mixing box is increased, and it is easier to flow out the internal components contained in the materials.

[0021] 2. Through the dispersedly designed leakage holes, the materials are more evenly dispersed, and the dispersion uniformity of the materials in the extractant is improved.

[0022] 3. The extractant can seep downward into the materials between the support screen and the screen. The extractant fully contacts the materials for extraction, and the extraction efficiency can be improved; when the red clover materials are extruded between the inner screen and the support screen, the screen can seep out the juice or extract liquid extruded from the red clover. After the juice is collected, it is mixed into the extractant, and the mixing effect is good, the extraction is more sufficient, and it is beneficial to shorten the extraction time.

Detailed implementation manners

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0031] In this article, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0033] Such as Figures 1-5As shown in the figure, a production processing device for red clover is used to process the crushed red clover material, including: a mixing tank 1 for containing an extractant; an outer cylinder 2 arranged at the lower end of the mixing tank 1 and communicating with the mixing tank 1; a support net 3 arranged at the upper end of the outer cylinder 2, and the support net 3 is provided with a number of material leakage holes 301; an inner cylinder 4 arranged to move up and down relative to the outer cylinder 2, the upper part of the inner cylinder 4 is slidably sealed with the inner wall of the outer cylinder 2, the upper end of the inner cylinder 4 is provided with a sieve mesh 5, the sieve mesh 5 and the support net 3 are arranged to move relative to each other, and the space between the sieve mesh 5 and the support net 3 is used to contain the material. After the inner cylinder 4 moves close to the support net 3, the material enters the mixing tank 1 through the material leakage holes 301.

[0034] During use, the crushed red clover material is placed above the sieve mesh 5, an extractant is introduced into the mixing tank 1, the sieve mesh 5 moves upward close to the support net 3, and under strong extrusion, the material passes upward through the material leakage holes 301 into the mixing tank 1 to fully contact the extractant. When passing through the material leakage holes 301, the material is further cut or frictionally damaged, which is beneficial to increasing the total contact area with the extractant, and the material is more evenly dispersed in the mixing tank 1 through the material leakage holes 301.

[0035] A fluid extractant can be introduced into the mixing tank 1, that is, a liquid inlet pipe and a liquid outlet pipe are arranged on the mixing tank 1, and the flow ability is provided by a pump structure or by using a height difference. Finally, a sufficient amount of extractant contacts the material, and it can be transferred and collected in a unified manner in a box body to extend the extraction time. The mixing tank 1 can also adopt a thin design, that is, increasing the plane area of the extractant and reducing the thickness of the extractant. After being dispersed through the material leakage holes 301 of the support net 3, the material is more evenly dispersed in the extractant. After sufficient extraction time, the next operation can be carried out.

[0036] When the inner cylinder 4 moves up and down relative to the outer cylinder 2, in addition to forming extrusion when moving relatively close, pressurizing the material between the sieve mesh 5 and the support net 3 and extruding the material from the material leakage holes 301 under pressure, the inner cylinder 4 can also periodically move away from the outer cylinder 2, that is, the sieve mesh 5 moves away from the support net 3, and the space between the two increases accordingly. Then, a large amount of extractant can be sucked into the space between the sieve mesh 5 and the support net 3 to make the extractant and the material fully contact. When the sieve mesh 5 and the support net 3 move close again to extrude, some of the extract liquid and juice between the sieve mesh 5 and the support net 3 are discharged upward through the material leakage holes 301, which can achieve a relatively uniform stirring effect and will not form a centrifugal stirring effect. Some of the extract liquid and juice can be discharged from the sieve mesh 5 and collected, and can be added to the extractant again to ensure component extraction. The density of the sieve mesh 5 is relatively large and greater than the density of the material leakage holes 301 on the support net 3, which is used to filter the liquid. The discharged liquid can be collected or diverted through a conventional collection device.

[0037] After the extraction is completed within a certain period of time, the mixture can be introduced into an existing precipitation device or filtration device for separating the extract and the extraction residue. Alternatively, the inner cylinder 4 can be moved downward, increasing the space between the screen 5 and the support screen 3, sucking the upper mixture, and then filtering it through the screen 5 to obtain the extract and the extraction residue.

[0038] The outer cylinder 2 can be provided with a feed channel and a discharge channel to facilitate the feeding of the crushed red clover material and the removal of the extraction residue. The relative stroke between the outer cylinder 2 and the inner cylinder 4 can also be increased so that the inner cylinder 4 can be moved out from the lower end inside the outer cylinder 2, thereby exposing the space for easy loading and unloading.

[0039] Furthermore, the support screen 3 is rotatably arranged at the upper end of the outer cylinder 2.

[0040] During use, the support screen 3 is rotatably arranged, which is conducive to improving the destruction efficiency of the material, reducing the blockage of the leakage holes 301, and driving the flow of the mixture in the mixing box 1. The rotation of the support screen 3 has a turbulence effect but a weak centrifugal effect.

[0041] A driving motor 9 can be arranged above the mixing box 1 to drive the support screen 3 to rotate through the connecting frame 901.

[0042] Furthermore, it also includes: a sealing plug 6, which is slidably and sealingly arranged inside the inner cylinder 4. The sealing plug 6 slides closer to or farther away from the screen 5, and the space between the sealing plug 6 and the screen 5 is used to accommodate the extractant that seeps down from the material above the screen 5.

[0043] During use, by designing the sealing plug 6, the filtering effect of the screen 5 can be controlled, and the extractant and the material can be kept in contact for a longer time between the support screen 3 and the screen 5. At the same time, the sealing plug 6 and the inner cylinder 4 form a syringe structure, which can control the fluidity of the mixed material between the support screen 3 and the screen 5.

[0044] When the screen 5 is away from the support screen 3, the extractant can be drawn into the space between the screen 5 and the support screen 3; the extractant can also be drawn by the movement of the sealing plug 6. Even if the screen 5 and the support screen 3 remain stationary or are relatively close and squeezed, the sealing plug 6 can move away from the screen 5 to form a negative pressure space, thereby drawing the upper extractant. Of course, when the space between the screen 5 and the support screen 3 is relatively loose, the extraction of the extractant is easier. The extractant flows through the material, and the gaps between the materials are filled with the extractant. Then the sealing plug 6 moves upward to push out the extractant, making the extractant around the material flow fully. When the space between the screen 5 and the support screen 3 is relatively loose, although the sealing plug 6 pushes out the extractant and is blocked by the screen 5, it can still cause turbulence to the material and the extractant between the screen 5 and the support screen 3, improving the fluidity and ensuring the full contact between the extractant and the material.

[0045] Through the control of the sealing plug 6, the extraction liquid will not be discharged at any time, but can be discharged periodically after a certain period of time, thereby ensuring the extraction efficiency and the full use of the extraction agent.

[0046] Furthermore, at least one drainage hole 401 is provided in a ring shape along the circumferential side wall of the inner cylinder 4. After the sealing plug 6 moves away from the screen 5 and moves below the drainage hole 401, the drainage hole 401 is connected to the space between the sealing plug 6 and the screen 5. The inner cylinder 4 also has a water receiving pool 402 on the outer periphery of the lower part. The extractant between the sealing plug 6 and the screen 5 is discharged from the drainage hole 401 into the water receiving pool 402.

[0047] When in use, there is a certain interval between the drainage hole 401 on the side wall of the inner cylinder 4 and the screen 5, and the sealing plug 6 moves in the interval, and the extractant can be extracted or pushed out by negative pressure and pressure. When the sealing plug 6 moves downward to expose the drainage hole 401, the extract above the sealing plug 6 can be discharged from the drainage hole 401, and the discharged extract can be collected uniformly or added to the mixing box 1 above. An annular water receiving pool 402 can be formed on the outer periphery of the lower part of the inner cylinder 4 through an annular fence to transfer and collect the extract discharged from the drainage hole 401.

[0048] When it is necessary to separate the extraction residue and the extraction liquid, the sealing plug 6 moves back and forth to continuously extract the extraction liquid, and finally obtains the extraction residue above the screen 5.

[0049] Furthermore, a sealing portion 403 is provided on the outer periphery of the upper portion of the inner tube 4 . The sealing portion 403 is slidably and sealingly arranged on the inner wall of the outer tube 2 . There is a gap between the outer wall of the inner tube 4 and the inner wall of the outer tube 2 .

[0050] When in use, the upper portion of the inner tube 4 is slidably sealed with the inner wall of the outer tube 2 via the annular sealing portion 403 .

[0051] Furthermore, it also includes: a first linear drive mechanism 7 for driving the outer tube 2 and the inner tube 4 to rise and fall relative to each other; and a second linear drive mechanism 8 disposed at the lower inner end of the inner tube 4 for driving the sealing plug 6 to slide inside the inner tube 4.

[0052] When in use, the linear drive mechanism can use a hydraulic component to provide a linear reciprocating drive capability. The first linear drive mechanism 7 can be installed at the lower end of the mixing box 1, and the moving end can be fixedly installed at the lower end of the inner cylinder 4, so as to drive the lifting and movement of the inner cylinder 4 and the outer cylinder 2. The outer cylinder 2 can also be fixed, and the first linear drive mechanism 7 can drive the lifting and movement of the inner cylinder 4.

[0053] The sealing plug 6 follows the inner tube 4 to rise and fall, and the second linear drive mechanism 8 can independently control the rising and falling of the sealing plug 6 .

[0054] It is understood that the present invention is described by way of some embodiments, and those skilled in the art will know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present invention. Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
