Description

Technical Field

[0001] The utility model belongs to the technical field of aqueous two-phase extraction, and particularly relates to an ultrasonic-assisted aqueous two-phase extraction device for tea bran polysaccharide. Background Art

[0002] The principle of ultrasonic-assisted aqueous two-phase extraction of tea bran polysaccharide is mainly to utilize the mechanical vibration effect and cavitation effect of ultrasonic waves to improve the efficiency of releasing and transferring tea bran polysaccharide from raw materials to the extraction phase. Under ultrasonic assistance, the partition coefficient of tea bran polysaccharide in the aqueous two-phase system will be affected, making the polysaccharide more likely to be distributed into the upper phase rich in polyethylene glycol (PEG). The composition and ratio of the upper phase and the lower phase can be adjusted to optimize the extraction efficiency of tea bran polysaccharide.

[0003] In traditional operations, the up-and-down movement of the ultrasonic transducer and the operation when the extraction container is transferred from the extraction station to the cleaning station usually need to be completed manually. This not only takes time and effort, but also easily causes equipment damage or poor extraction effect due to improper operation. During the manual operation process, mistakes are likely to occur, resulting in inaccurate extraction results. Therefore, the traditional extraction operation of tea bran polysaccharide usually relies on manual operation, with cumbersome steps, low efficiency, and certain safety risks. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the utility model provides an ultrasonic-assisted aqueous two-phase extraction device for tea bran polysaccharide.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] An ultrasonic-assisted aqueous two-phase extraction device for tea bran polysaccharide, comprising:

[0007] A lead screw linear module, which is arranged vertically and is used to drive the ultrasonic transducer to move up and down;

[0008] A rotary cylinder, which is used to drive the clamping bracket to rotate and drive the extraction container clamped on the clamping bracket to switch back and forth between the extraction station and the cleaning station;

[0009] When the extraction container is vertically aligned with the ultrasonic transducer, it is in the extraction station. The lead screw linear module is actuated to drive the ultrasonic transducer to move down and insert it into the tea bran sample loaded in the extraction container, and the extraction efficiency of the tea bran sample is enhanced through the high-frequency vibration of the ultrasonic waves.

[0010] Preferably, the ultrasonic transducer is electrically connected to the controller through a cable. The ultrasonic transducer and the controller together constitute an ultrasonic generator. The ultrasonic transducer is used to convert electrical energy into mechanical vibration, and the controller is used to adjust the frequency and intensity of the ultrasonic waves.

[0011] The ultrasonic generator is the core part of the ultrasonic extraction system, responsible for generating high-frequency vibrations. Through the synergistic effect of the high-frequency vibrations of ultrasonic waves and aqueous two-phase extraction, the extraction efficiency and purity of tea bran polysaccharides are improved.

[0012] Preferably, the clamping bracket includes a vertical shaft fixedly connected to a swing plate at the end of the piston rod of the rotary cylinder, two mounting seats arranged up and down, a hoop A for locking and fixing the vertical shaft on one side of the mounting seat, and a hoop B for locking and fixing the extraction container on the other side of the mounting seat.

[0013] Preferably, the extraction container is in a straight cylindrical shape and made of a transparent material, and a discharge valve is provided at its bottom. The extraction container is the container for the actual extraction process, usually made of a transparent material for easy observation of the internal situation. The extraction container needs to be able to withstand ultrasonic vibrations and prevent ultrasonic leakage; the hoop B is also made of a transparent material, which is both transparent for easy observation of the internal situation of the extraction container and effective in fixing the extraction container on the mounting seat.

[0014] Compared with the prior art, the technical effects and advantages of the present utility model are:

[0015] By using automatic control components such as a lead screw linear module and a rotary cylinder, the automatic up and down movement of the ultrasonic transducer, the automatic rotation and switching of the extraction container are realized, greatly improving the degree of automation of the operation. Due to the automatic operation of the device, the error risk caused by improper manual operation can be reduced, and the stability and accuracy of the extraction process are improved. The high-frequency vibrations of ultrasonic waves can effectively destroy the structure of tea bran, increase the contact area between polysaccharides and solvents, accelerate the extraction speed, and improve the extraction efficiency.

[0016] Compared with the traditional extraction operation of tea bran polysaccharides, which usually relies on manual operation, has relatively cumbersome steps and low efficiency, the ultrasonic-assisted aqueous two-phase extraction device for tea bran polysaccharides improves the operation efficiency and safety through automated equipment and intelligent control, and reduces the complexity of manual operation.

Detailed implementation mode

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The following will further describe the present application in detail Figures 1-3 with reference to the attached drawings.

[0023] The embodiment of the present application discloses an ultrasonic-assisted aqueous two-phase extraction device for tea saponin polysaccharide, including a screw linear module 4 arranged vertically and used to drive the ultrasonic transducer 7 to move up and down, and a rotary cylinder 11 used to drive the clamping bracket 10 to rotate and drive the extraction container 12 clamped on the clamping bracket 10 to switch back and forth between the extraction station and the cleaning station.

[0024] The screw linear module 4 can drive the ultrasonic transducer 7 to insert into or pull out of the extraction container 12. The rotary cylinder 11 can drive the clamping bracket 10 and the extraction container 12 to perform the work of aqueous two-phase extraction of tea saponin polysaccharide at the extraction station, and can also drive the extraction container 12 at the cleaning station to clean or clear the extraction container 12 at the cleaning station.

[0025] Through the cooperation of the lead screw linear module 4 and the rotary cylinder 11, the automatic up and down movement of the ultrasonic transducer 7 and the automatic rotation and switching of the extraction container 12 are realized, which improves the automation level of the device. Due to the automatic operation of the device, the complexity of manual operation is reduced, the risk of operation errors is lowered, and human resources are saved at the same time. The high-frequency vibration of the ultrasonic wave can effectively break the structure of the tea bran, increase the contact area between the polysaccharide and the solvent, accelerate the extraction speed, and improve the extraction efficiency. The rotary cylinder 11 can ensure that the extraction container 12 is stably placed at the extraction station, which is conducive to the effective extraction of tea bran polysaccharide by the ultrasonic transducer 7. At the same time, cleaning or cleaning operations are carried out at the cleaning station, ensuring the smooth progress of the extraction process. The design of this device allows different operations to be carried out at different stations, such as extraction, cleaning or cleaning. Such a design provides convenience for the optimization and adjustment of the process flow. The cleaning station in the design makes the cleaning or cleaning of the extraction container 12 convenient and fast, which helps to keep the extraction equipment clean and the quality of the polysaccharide product stable.

[0026] The lead screw linear module 4 is fixed on the vertical plate 1, the vertical plate 1 is fixed on the top of the base 6, the rotary cylinder 11 is fixed on the support 13, and the support 13 is fixed on the top of the base 6;

[0027] The moving slide 2 on the lead screw linear module 4 is fixedly connected with the moving seat 3, and the ultrasonic transducer 7 is embedded on the moving seat 3. When the extraction container 12 is vertically aligned with the ultrasonic transducer 7, it is at the extraction station. The lead screw linear module 4 is actuated to drive the ultrasonic transducer 7 to move down and insert into the loaded tea bran sample in the extraction container 12, and the extraction efficiency of the tea bran sample is enhanced by the high-frequency vibration of the ultrasonic wave.

[0028] An upper cover 9 covering the outside of the top of the extraction container 12 is provided on the housing of the ultrasonic transducer 7. The ultrasonic transducer 7 is electrically connected to the controller 5 through a cable. The ultrasonic transducer 7 and the controller 5 are combined to form an ultrasonic generator. The ultrasonic transducer 7 is used to convert electrical energy into mechanical vibration, and the controller 5 is used to adjust the frequency and intensity of the ultrasonic wave.

[0029] The principle of ultrasonic-assisted aqueous two-phase extraction of tea bran polysaccharide is mainly based on the high-frequency vibration effect of ultrasonic waves. The ultrasonic transducer 7 converts electrical energy into mechanical vibration. Through its high-frequency vibration in the tea bran sample, the contact and mixing between the sample and the solvent can be enhanced, the molecular diffusion efficiency can be improved, and thus the extraction efficiency of tea bran polysaccharide can be improved.

[0030] High-frequency vibration helps to better break the sample structure and release effective components such as tea bran polysaccharide, thereby increasing the extraction rate. Ultrasonic vibration can quickly break the sample structure and mix the solvent, so the extraction process can be completed in a shorter time. Ultrasonic extraction can more effectively separate the target components and sometimes obtain products with higher purity.

[0031] The clamping bracket 10 includes a vertical shaft 15 fixedly connected to the swing plate 8 at the end of the piston rod of the rotary cylinder 11, two mounting seats 16 arranged vertically, a hoop A17 for locking and fixing the vertical shaft 15 on one side of the mounting seat 16, and a hoop B18 for locking and fixing the extraction container 12 on the other side of the mounting seat 16.

[0032] The movement of the swing plate 8 is controlled by the rotary cylinder 11, thereby controlling the clamping bracket 10 to switch back and forth between the extraction station and the cleaning station. The vertical shaft 15 serves as a support part to connect the swing plate 8 and the hoop A17, providing stability for the clamping bracket 10. The mounting seats 16 are arranged vertically to fix the hoops, ensuring the stability and correct position of the entire bracket. The hoop A17 is used to lock the vertical shaft 15, guaranteeing stability during the operation and preventing displacement caused by vibration or improper operation. The hoop B18 is used to lock and fix the extraction container 12 on the other side of the mounting seat 16, ensuring the stability and safety of the extraction container 12 during the extraction process.

[0033] The extraction container 12 is in a straight cylindrical shape, made of a transparent material, and a discharge valve 14 is provided at its bottom. The hoop B18 is also made of a transparent material.

[0034] The extraction container 12 is a container for the actual extraction process, usually made of a transparent material for easy observation of the internal situation. The extraction container 12 needs to be able to withstand ultrasonic vibration and prevent ultrasonic leakage. The extraction container 12 can be made of polycarbonate (PC) or borosilicate glass. Polycarbonate is a high-strength, high-transparency engineering plastic that can withstand ultrasonic vibration and has good tolerance to most chemical substances. Borosilicate glass has high transparency and good heat and chemical resistance.

[0035] The hoop B18 should be transparent for easy observation of the internal situation of the extraction container 12 and effectively fix the extraction container 12 on the mounting seat 16. The hoop B18 is made of transparent plastic.

[0036] The working process of this ultrasonic-assisted aqueous two-phase extraction device for tea saponin polysaccharide can be summarized as follows:

[0037] 1. Preparation stage: Load the tea saponin sample into the extraction container 12 and fix the extraction container 12 on the clamping bracket 10. The extraction container 12 is vertically aligned with the ultrasonic transducer 7 to facilitate the transmission of high-frequency vibration when the ultrasonic transducer 7 extends into the extraction container 12.

[0038] 2. Positioning stage: Move the ultrasonic transducer 7 into the material in the extraction container 12 through the lead screw linear module 4 to prepare for the extraction operation.

[0039] 3. Extraction stage: Start the ultrasonic transducer 7, cover the upper cover 9 on the outer side of the top of the extraction container 12 on its housing, and ensure that the ultrasonic energy can be effectively transmitted to the tea bran sample. The ultrasonic transducer 7 converts electrical energy into high-frequency mechanical vibrations, which pass through the tea bran sample, break its structure, increase the contact and mixing between the polysaccharide and the solvent, and improve the molecular diffusion efficiency.

[0040] 4. Monitoring of the extraction process: Adjust the frequency and intensity of the ultrasonic wave through the controller 5 to optimize the extraction process. The controller 5 can remotely control the operation of the ultrasonic transducer 7 to achieve precise control of the extraction process.

[0041] 5. After the extraction is completed, stop the ultrasonic vibration, pull out the ultrasonic transducer 7 and the extraction container 12 through the lead screw linear module 4, and open the discharge valve 14 for phase separation and material taking work;

[0042] 6. After the sampling is completed, the rotary cylinder 11 operates to transfer the extraction container 12 from the extraction station to the cleaning station. At the cleaning station, the extraction container 12 can be cleaned or cleared mechanically or manually to remove the residual tea bran polysaccharide and other substances, and maintain the cleanliness of the equipment and the efficiency of the next extraction.

[0043] 7. Recycling: After the cleaning / clearing is completed, the extraction container 12 can return to the extraction station and repeat the above extraction process to achieve continuous production operation.

[0044] The degree of automation of the entire work process is high, reducing the need for manual operation, reducing the risk of operation errors, and at the same time improving the extraction efficiency and product quality. Through the cleaning station in the design, the continuous cleanliness of the equipment can be ensured, thereby maintaining the consistency and quality of the product.
