Description

Technical Field

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

[0002] Tea pigments are a class of plant phenolic pigments, primarily composed of catechins, formed through enzymatic or non-enzymatic oxidation of tea polyphenols. Due to their diverse pharmacological effects, tea pigments have promising applications in food, medicine, and other fields, making them a highly promising natural tea product. The purification process for tea pigments generally involves purification, filtration, and extraction. Purification typically requires the addition of purification reagents, which react with the tea pigments extracted from the tea leaves. After filtering out excess tea residue, the reaction mixture of the purification reagent and the tea pigments is further separated and dried to obtain the final tea pigment.

[0003] The application document for a separation and purification device for tea pigment processing, with application number 202221254969.8, includes a connecting cleaning mechanism that can scrape the inner wall of the extraction tank and support the filter cartridge. The stirring device can not only stir the extract in the filter cartridge but also backwash the filter cartridge. The heating device ensures the temperature inside the extraction tank and accelerates the purification speed.

[0004] While the aforementioned applications meet the user's needs to a certain extent, certain shortcomings still exist during use. Specific problems are as follows: relying on a single stirring structure or natural mixing method results in insufficient uniform contact between tea leaves and purification reagents, low mixing efficiency, and insufficient dissolution of tea pigments into the reagents, leading to low extraction rates and waste of raw materials. Furthermore, the separation of tea residues from the extract often requires additional equipment or manual operation during the extraction process, making the process cumbersome. Additionally, leakage of the extract or contamination of residues can easily occur during separation, affecting subsequent purification purity and increasing operating and time costs. Based on these issues, this utility model designs a separation and purification device for tea pigment extraction to solve the above problems. Utility Model Content

[0005] This invention provides a separation and purification device for tea pigment extraction, which can effectively solve the problems mentioned in the background art, such as reliance on a single stirring structure or natural mixing method, insufficient uniform contact between tea leaves and purification reagents, low mixing efficiency, resulting in insufficient dissolution of tea pigments into the reagents, low extraction rate, and waste of raw materials. In addition, the separation of tea residue from the extract often requires additional equipment or manual operation during the extraction process, which is cumbersome. Furthermore, the separation process is prone to problems such as leakage of extract or contamination of residues, which affect the purity of subsequent purification and increase operating and time costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a separation and purification device for extracting tea pigments, comprising a purification cylinder, a discharge hole welded through one end of the bottom of the purification cylinder, a cylinder cover installed on the top of the purification cylinder by screws, an air outlet welded through one end of the top of the cylinder cover, a heat-conducting plate installed inside the purification cylinder by screws, and a heating wire installed at the bottom of the heat-conducting plate by screws. The purification cylinder is equipped with a first stirring blade for stirring the solution, and the top of the purification cylinder is equipped with a filter cylinder and a rotating plate for placing tea leaves. The filter cylinder is equipped with a second stirring blade for stirring the tea leaves. The first stirring blade and the second stirring blade are driven synchronously by a motor.

[0007] A separation and purification device for extracting tea pigments, preferably, has a motor installed at the bottom of the purification cylinder by screws, a stirring shaft fixedly connected to the output shaft of the motor, and first stirring blades evenly installed on the outer side of the stirring shaft by screws.

[0008] A separation and purification device for extracting tea pigments, preferably, has a filter cylinder installed at the bottom of the cylinder cover by screws, a rotating plate rotatably connected to the bottom of the filter cylinder, an insertion rod welded to the bottom of the rotating plate, a sealing plate placed at the top of the cylinder cover, a drive shaft rotatably connected to the bottom of the sealing plate, a second stirring blade uniformly fixedly sleeved on the outside of the drive shaft, a placement plate fixedly connected to the bottom of the drive shaft, and insertion columns uniformly welded to the bottom of the placement plate.

[0009] A separation and purification device for extracting tea pigments, preferably wherein the stirring shaft and the heat-conducting plate are connected by a mechanical seal.

[0010] A separation and purification device for extracting tea pigments, preferably wherein a T-ring is welded to the top of the rotating plate, and the T-ring is embedded and rotatably connected to the bottom of the filter cylinder.

[0012] A separation and purification device for extracting tea pigments, preferably, has a corresponding groove on the top surface of the rotating plate at the position of the corresponding insertion column, and the outer side of the insertion column is in contact with the inner wall of the corresponding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The structure of this utility model is scientific and reasonable, and it is safe and convenient to use: The device is equipped with a dual stirring structure. The first stirring blade driven by the motor can stir the purification reagent in the purification cylinder, and at the same time drive the rotating plate at the bottom of the filter cylinder and the second stirring blade below the sealing plate to rotate. The second stirring blade directly stirs the tea leaves in the filter cylinder, so that the tea leaves and the purification reagent are in all-round and uniform contact, which greatly improves the mixing efficiency, ensures that the tea pigment is fully dissolved, and improves the extraction rate. The filter cartridge is built into the purification cartridge. The tea leaves are placed directly into the filter cartridge. After extraction, the rotation of the rotating plate helps to separate the tea residue from the extract. No additional transfer equipment is needed. The combination of the filter cartridge and the rotating plate can effectively prevent tea residue from entering the purification liquid, ensuring the purity of subsequent purification and reducing interference from impurities. The heat-conducting plate inside the purification cylinder works in conjunction with the bottom heating wire to evenly conduct heat and precisely control the temperature inside the purification cylinder, providing a suitable environment for the dissolution of tea pigments and promoting the extraction reaction. The sealing plate of the device can be directly removed from the top of the cylinder cover, making it easy to put in and take out tea leaves. The matching design of the insertion rod and stirring shaft insertion slot, and the corresponding slot of the insertion column and rotating plate makes the linkage assembly of each component simple and convenient. Installation and disassembly can be completed without complicated tools, reducing the difficulty of operation and improving the convenience of use. Attached Figure Description

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example: Figure 1-4 As shown, the present invention provides a technical solution: a separation and purification device for extracting tea pigments, including a purification cylinder 1, a discharge hole 2 welded through one end of the bottom of the purification cylinder 1, a cylinder cover 3 installed on the top of the purification cylinder 1 by screws, an air outlet 4 welded through one end of the top of the cylinder cover 3, a heat-conducting plate 5 installed inside the purification cylinder 1 by screws, and a heating wire 6 installed at the bottom of the heat-conducting plate 5 by screws. A motor 7 is installed at the bottom of the purification cylinder 1 by screws. The output shaft of the motor 7 is fixedly connected to a stirring shaft 8. First stirring blades 9 are evenly installed on the outer side of the stirring shaft 8 by screws. A filter cylinder 10 is installed at the bottom of the cylinder cover 3 by screws. A rotating plate 11 is embedded and rotatably connected to the bottom of the filter cylinder 10. An insertion rod 12 is welded to the bottom of the rotating plate 11. A sealing plate 13 is placed on the top of the cylinder cover 3. A drive shaft 14 is embedded and rotatably connected to the bottom of the sealing plate 13. A second stirring blade 15 is uniformly fixedly sleeved on the outside of the drive shaft 14. A placement plate 16 is fixedly connected to the bottom of the drive shaft 14. Insertion columns 17 are uniformly welded to the bottom of the placement plate 16.

[0018] The purification reagent can be added into the purification cylinder 1 through the air outlet 4. The stirring shaft 8 and the heat-conducting plate 5 are connected by a mechanical seal to avoid the problem of solution splashing out of the purification cylinder 1.

[0019] A T-ring is welded to the top of the rotating plate 11. The T-ring is embedded in the bottom of the filter cylinder 10 and rotates to prevent the rotating plate 11 from falling off.

[0020] An insertion groove is provided on the top surface of the stirring shaft 8 at the position corresponding to the insertion rod 12. The insertion rod 12 is located inside the insertion groove, which facilitates the rotation of the insertion rod 12, thereby driving the rotating plate 11 to rotate.

[0021] The top surface of the rotating plate 11 has a corresponding groove at the position of the insertion column 17. The outer side of the insertion column 17 is in contact with the inner wall of the corresponding groove to ensure the stability of the placement plate 16 and facilitate the rotation of the placement plate 16 to achieve the stirring of tea leaves.

[0022] First, open the sealing plate 13 and put the tea leaves to be extracted into the filter cylinder 10. Then, close the sealing plate 13 and insert the insertion post 17 on the bottom drive shaft 14 of the sealing plate 13 into the corresponding groove on the top of the rotating plate 11. At the same time, ensure that the insertion rod 12 at the bottom of the rotating plate 11 is inserted into the insertion groove on the top surface of the stirring shaft 8 to complete the assembly of the stirring linkage structure. Finally, fix the cylinder cover 3 to the top of the purification cylinder 1 with screws to ensure the device is sealed. An appropriate amount of purification reagent is injected into the purification cylinder 1 through the air outlet 4 at the top of the cylinder cover 3. After entering the purification cylinder 1, the reagent will penetrate into the filter cylinder 10 and come into contact with the tea leaves. Then, the heating wire 6 at the bottom of the heat conduction plate 5 is activated. The heat conduction plate 5 evenly conducts heat to the solution in the purification cylinder 1. The heating temperature is adjusted to a suitable range according to the requirements of the tea pigment extraction process. The motor 7 at the bottom of the purification cylinder 1 is started. The output shaft of the motor 7 drives the stirring shaft 8 to rotate. The first stirring blade 9 on the outside of the stirring shaft 8 rotates synchronously to stir the purification reagent in the purification cylinder 1 and promote reagent circulation. At the same time, the stirring shaft 8 drives the rotating plate 11 to rotate through the cooperation of the insertion groove and the insertion rod 12. The rotating plate 11 then drives the placement plate 16 and the driving shaft 14 to rotate through the cooperation of the corresponding groove and the insertion column 17. The second stirring blade 15 on the outside of the shaft 14 directly stirs the tea leaves in the filter cylinder 10, so that the tea leaves and the purification reagent are in full contact and the tea pigment is dissolved into the reagent. After extraction, turn off motor 7 and heating wire 6, and let the solution stand for a while. Filter cylinder 10 blocks tea residue, and the purified liquid is retained at the bottom of purification cylinder 1. Finally, open the discharge hole 2 at the bottom of purification cylinder 1 to discharge the purified liquid into the subsequent processing equipment, thus completing the separation and purification of tea pigments. If extraction is required again, the sealing plate 13 can be removed to replace the tea leaves in filter cylinder 10, and the above steps can be repeated.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
