Description

Technical Field

[0001] This utility model relates to the field of tea polyphenol extraction technology, specifically to a tea polyphenol separation and extraction device. Background Technology

[0002] Tea polyphenols are an important natural component extracted from tea leaves. They have various biological activities, such as preventing and treating cardiovascular diseases, anti-cancer and anti-mutation, antibacterial and deodorizing, and lowering blood pressure and blood sugar. The current mainstream extraction method is to extract tea leaves in organic solvents. The principle is to extract and separate different compounds in tea leaves by utilizing the differences in solubility in different solvents. This method is relatively simple, but the effect is not very good. It requires multiple distillations and the heating time is too long, which makes tea polyphenols easy to oxidize.

[0003] For example, Chinese Patent (Announcement No.: CN214388970U) discloses a high-purity tea polyphenol separation and extraction device, including a separation box and a support leg fixedly installed on the bottom wall of the separation box. A discharge pipe is sealed to the front wall of the separation box, and a feed box is sealed to the top wall of the separation box. A crushing and mixing mechanism is provided on the separation box, and a filter plate is fixedly installed inside the separation box. A storage cavity is opened on the inner wall of the separation box, and the right wall of the storage cavity corresponds to the left wall of the filter plate. In the process of use, the tea leaves are crushed and mixed by the crushing and mixing mechanism. The mixed tea leaves are then transported to the upper wall of the filter plate for filtration. After working for a period of time, the cleaning plate can be moved to the left by the moving mechanism. The cleaning plate will clean the residue attached to the surface of the filter plate into the storage cavity and finally discharge it through the slag discharge pipe, which can reduce the risk of filter plate clogging.

[0004] The aforementioned patent uses a moving mechanism to clean the residue on the surface of the filter plate, thereby reducing filter plate clogging. However, it has low extraction efficiency for tea polyphenols, and tea polyphenols are prone to oxidation and quality reduction when soaking for a long time. Therefore, a tea polyphenol separation and extraction device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This embodiment of a tea polyphenol separation and extraction device includes a housing 1. Translation holes are provided on both the left and right side walls of the housing 1. Two rubber strips, fitted together front and back, are fixed within the translation holes to prevent tea leaves from flowing out of the housing 1. A crushing assembly 2 for crushing tea leaves is provided on the top of the housing 1. The crushing assembly 2 includes a grinding chamber 201 fixed to the top of the housing 1 and extending into the housing 1. A first drive motor 202 is fixed to the top of the housing 1. A drive rod 203 extending through the grinding chamber 201 is fixed to the output shaft of the first drive motor 202. The left side wall of the inner cavity of the grinding chamber 201 is... A bearing is rotatably connected to a follower rod 205 extending through the right side to the outside of the crushing box 201. The outer surfaces of both the drive rod 203 and the follower rod 205 are fixed with intermeshing rollers 204 located inside the crushing box 201. The outer surface of the rollers 204 is fixed with a plurality of evenly distributed cutting teeth. The right sides of both the drive rod 203 and the follower rod 205 are fixed with intermeshing rotating gears 206. By driving the first drive motor 202, the drive rod 203 is rotated, causing the two intermeshing rotating gears 206 to operate, so that the rollers 204 work synchronously, achieving efficient tea crushing.

[0027] A drive box 4 and a fixed box 5 are fixed on the left and right sides of the box body 1, respectively. The drive box 4 is equipped with a transmission mechanism 3 that passes through the drive box 4 and the box body 1 and extends into the fixed box 5 for stirring and mixing. The inner cavity of the box body 1 is equipped with a crushing component 6 that passes through the box body 1, extends into the drive box 4 and meshes with the transmission mechanism 3. A water inlet pipe 7 that passes through the fixed box 5 is fixed on the right side of the box body 1. Long through holes are opened on opposite sides of the drive box 4 and the fixed box 5. The long through hole on the left side is longer than the long through hole on the right side. A discharge pipe 8 is fixed on the left side of the box body 1. Multiple ultrasonic vibrating rods 9 are fixed on the bottom wall of the inner cavity of the box body 1 in a uniform distribution. The high-frequency sound waves of the ultrasonic waves generated by the multiple ultrasonic vibrating rods 9 can be used to stir the solution and further improve the full mixing of tea polyphenols in tea leaves with the solution.

[0028] Additional explanation: The compaction assembly 6 includes a second driven bevel tooth 605 that meshes with the second active bevel tooth 393. A stabilizing rod 604 that penetrates the housing 1 is fixed at the axis of the second driven bevel tooth 605. Connecting bearings are fixed on both the left and right sides of the outer surface of the stabilizing rod 604. A load-bearing rod 607 that is fixed to the support rod 311 is fixed at the bottom of each of the two connecting bearings. A connecting rod 606 that penetrates into the drive housing 4 and is movably connected to the outer surface of the rotating rod 391 is fixed at the top of the left connecting bearing. The connecting rod 606 is rotatably connected to the outer surface of the rotating rod 391 through the bearing. Two moving blocks 603 that are both located in the inner cavity of the housing 1 are threadedly connected to the outer surface of the stabilizing rod 604. A compaction part 602 is fixed at the bottom of each of the two moving blocks 603.

[0029] It is necessary to explain that a filter frame 601 located in the inner cavity of the housing 1 is movably connected between the two support rods 311. A limit rod is fixed in the inner cavity of the filter frame 601. The crushing part 602 extends into the filter frame 601 and is penetrated by the limit rod and slidably connected to the limit rod. The filter frame 601 is a stainless steel mesh frame. A handle is fixed on the front of the filter frame 601. A sliding door that is hinged is fixed on the outer surface of the housing 1 and on the front of the filter frame 601.

[0030] Under the meshing force of the transmission mechanism 3 and the second driven bevel tooth 605, the stabilizing rod 604 is driven to rotate, thereby causing the two moving blocks 603 to be relatively displaced on the stabilizing rod 604, so that the crushing part 602 squeezes the tea leaves in the filter frame 601, thereby better releasing the tea polyphenols in the tea leaves.

[0031] Additionally, both grinding sections 602 consist of a grinding cylinder, a receiving rod, and a connecting rod. The connecting rod is fixed to the bottom of the moving block 603, and the bottom of the connecting rod extends to the inside of the filter frame 601. A receiving rod is fixed to the inside of the connecting rod, and the grinding cylinder is movably connected to the outer surface of the receiving rod. The grinding cylinder effectively further compresses the crushed tea leaves in the filter frame 601, so that the tea polyphenols produced during the grinding process mix with the solution while the tea leaves themselves remain in the filter frame 601, thereby achieving efficient mixing and improving extraction efficiency.

[0032] In this embodiment, tea leaves are first placed into the crushing component 2. Under the action of the crushing component 2, the tea leaves are fully crushed and then fall into the grinding component 6. At this time, the transfer mechanism 3 is activated, which will drive the grinding component 6 to slowly descend. At the same time, the grinding component 6 itself will start to operate, fully stirring the tea leaves inside. Simultaneously, the ultrasonic vibrator 9 is turned on to generate high-frequency vibration in the solution, which promotes the full mixing of the solution and the tea polyphenols in the tea leaves. Finally, the fully mixed solution and tea polyphenols are discharged through the discharge pipe 8, realizing the efficient extraction of tea polyphenols and effectively improving the extraction efficiency and extraction quality.

[0033] Please refer to it again. Figure 1 and Figure 4 as well as Figures 5 to 6 To ensure thorough mixing of tea polyphenols in the tea leaves with the solution, the transmission mechanism 3 in this embodiment includes a second drive motor 31 fixed to the bottom wall of the inner cavity of the drive box 4. The output shaft of the second drive motor 31 is fixed with a power rod 32 that passes sequentially through the drive box 4 and the box body 1 and extends into the fixed box 5. The right side of the power rod 32 is rotatably connected to the right side wall of the inner cavity of the fixed box 5 via a bearing. The outer surface of the power rod 32 is provided with a stirring part that penetrates into the box body 1. The stirring part consists of two force transmission rods 33 and two transmission parts 34. The force transmission rods 33 are rotatably connected to the right side wall of the inner cavity of the box body 1 via bearings. The left side of the transmission rod 33 passes through the housing 1 and extends into the drive housing 4. The outer surfaces of the two transmission rods 33 and inside the drive housing 4 are provided with transmission parts 34 that are connected to the power rod 32. The two transmission parts 34 are composed of a chain and two sprockets. The outer surfaces of the power rod 32 and the two transmission rods 33 are fixed with sprockets. The two sprockets are connected by a chain. The rotation of the sprocket on the power rod 32 drives the corresponding transmission rod 33 to rotate, thereby achieving the mixing and stirring of tea polyphenols and solution in the housing 1. Multiple stirring blades are fixed on the outer surfaces of the transmission rods 33 and inside the housing 1.

[0034] On the left and right sides of the outer surface of the power rod 32, respectively located within the inner cavities of the drive box 4 and the fixed box 5, are fixed first active bevel teeth 35. On opposite sides of the two first active bevel teeth 35, first driven bevel teeth 36 are engaged. Rotating rods 37 and transmission rods 38 are fixed at the axial centers of the two first driven bevel teeth 36, respectively. The top of the transmission rod 38 is rotatably connected to the top wall of the inner cavity of the fixed box 5 via bearings. Sliding blocks 310 are threaded onto the outer surfaces of both the rotating rod 37 and the transmission rod 38. On opposite sides of the two sliding blocks 310, there are fixed elements that penetrate the drive box 4 and the fixed box 5 and extend to the box body 1. The support rod 311 is movably connected to the crushing component 6. Both the support rod 311 and the moving block 603 pass through the translation hole and are in contact with the rubber strip. The rubber strip ensures that the tea leaves in the box 1 will not flow out when the support rod 311 and the moving block 603 move downwards at the same time. The long strip through hole on the left is passed through the connecting rod 606, the stabilizing rod 604 and the left support rod 311 from top to bottom. The long strip through hole on the right is passed through the right support rod 311. The long strip through hole on the left is used for the movement of the stabilizing rod 604 and the left support rod 311. The long strip through hole on the right is used for the movement of the right support rod 311.

[0035] The inner cavity of the rotating rod 37 is provided with a movable component 39 connected to the rolling assembly 6. The movable component 39 consists of a rotating rod 391, a sliding block 392, and a second active bevel gear 393. The inner cavity of the transmission rod 38 is movably connected to the rotating rod 391. Four sliding blocks 392 are fixed on the outer surface of the rotating rod 391 and slidably connected to the inner wall of the transmission rod 38. Four sliding grooves adapted to the sliding blocks 392 are opened on the side wall of the inner cavity of the transmission rod 38. The second active bevel gear 393 is fixed on the outer surface of the rotating rod 391 and on the side near the drive box 4. The rotating rod 37 drives the sliding blocks 392 to rotate. When the chute and its rotating rod 391 are rotated together, the stabilizing rod 604 is rotated through gear meshing, and the two rolling parts 602 are displaced to carry out rolling operations. When it is necessary to lower the height of the rolling assembly 6, the sliding block 310 is engaged with the corresponding rod body to drive the height adjustment of the sliding block 310. Under the pulling action of the load-bearing rod 607 and the rotational force eliminated by the bearing, the stabilizing rod 604 and the rotating rod 391 and other structures are adjusted in height together, thereby realizing the movement of the entire rolling assembly 6. The rotating rod 391 is rotated to transmit rotational power while the height is adjustable.

[0036] The filter frame 601 has mounting plates fixed on both its left and right sides, which penetrate into the support rod 311. The rear side wall of the inner cavity of the support rod 311 is fitted with a locking rod that penetrates the mounting plate and extends to the outside of the support rod 311. The side of the support rod 311 near the filter frame 601 has a mounting groove that matches the mounting plate and is flush with the front of the support rod 311. The rear side wall of the inner cavity of the support rod 311 has a locking groove that communicates with the mounting groove. The mounting plate has a locking through hole for the locking rod to pass through. When the mounting plate is inserted into the inner cavity of the support rod 311, the locking rod will pass through the locking through hole in the mounting plate and enter the locking groove, thereby achieving the effect of fixing and facilitating the disassembly of the filter frame 601.

[0037] In this embodiment, tea leaves are first placed into the crushing component 2. After being crushed in the crushing component 2, the tea leaves naturally fall into the crushing component 6. The second drive motor 31 is started, which drives the power rod 32 to rotate at high speed to stir the solution in the box 1. At the same time, as the power rod 32 rotates, the two bevel teeth mesh. Under the meshing force, the rotating rod 37 and the transmission rod 38 rotate, thereby driving the sliding block 310 to move and driving the support rod 311 to move. This, in turn, drives the moving component 39 and the crushing component 6 to move smoothly. At the same time, the crushing component 6 starts to operate, stirring the tea leaves inside to achieve the purpose of fully mixing tea polyphenols with the solution.

[0038] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0039] The working principle of the above embodiments is as follows:

[0040] 1. First, the tea leaves are put into the crushing component 2. After crushing, the tea leaves fall into the grinding component 6. Then, the second drive motor 31 is started, which drives the power rod 32 to rotate, so that the solution in the box 1 begins to stir. At the same time, the first active bevel tooth 35 and the first driven bevel tooth 36 mesh with each other. Under the meshing force, the rotating rod 37 and the transmission rod 38 rotate. When the moving component 39 is driven to rotate by the rotating rod 37, under the meshing force, the stabilizing rod 604 on the grinding component 6 is driven to rotate. Under the threaded connection force, the two grinding parts 602 are driven to move and grind the tea leaves in the filter frame 601, so as to promote better extraction of tea polyphenols.

[0041] 2. At the same time, as the second drive motor 31 rotates, it drives the sliding block 310 to move, which in turn moves the support rod 311. This, in turn, drives the moving component 39 and the crushing component 6 to sink smoothly. At the same time, the ultrasonic vibrating rod 9 is also turned on. The high-frequency vibration waves it generates cause the solution in the box 1 to mix and blend with the tea polyphenols in the tea leaves. Finally, the fully mixed extract is discharged from the discharge pipe 8, achieving efficient extraction of tea polyphenols and significantly improving extraction efficiency and product quality.
