Description

Technical Field

[0001] This utility model mainly relates to the field of lotus seed wine brewing technology, specifically a lotus ultrasonic circulation extraction device. Background Technology

[0002] Lotus flowers, the blossoms of plants in the genus Nelumbo, are rich in flavonoids, polysaccharides, volatile oils, and other bioactive components, which possess excellent antioxidant, antibacterial, and health-promoting effects. In the brewing of specialty wines such as lotus seed wine, lotus flowers or their extracts are often added to impart a unique flavor and color, and enhance their health benefits. Therefore, efficiently and fully extracting the effective components from lotus flowers is a key step in improving the quality and added value of lotus seed wine.

[0003] Currently, common methods for extracting active ingredients from plants in industrial production include decoction, maceration, and percolation. However, these traditional methods generally suffer from problems such as long extraction cycles, low efficiency, insufficient dissolution of active ingredients, and high energy consumption. Although ultrasonic-assisted extraction technology has been proven to be an effective means of solving the above problems due to its ability to significantly disrupt plant cell walls and accelerate mass transfer processes by utilizing cavitation effects, thereby improving extraction efficiency and yield, and has been gradually applied in related fields, existing ultrasonic extraction devices used in lotus seed wine brewing have limitations. If lotus residue remains in the tank for a long time during the extraction process, it may not only adsorb the dissolved effective components and cause waste, but may also break into fine particles under continuous ultrasonic vibration, resulting in turbidity of the extract. This directly affects the subsequent fusion effect with the lotus seed wine base liquor, thereby reducing the clarity and quality of the finished lotus seed wine. To address this, some devices have added a circulating filtration function to separate the residue from the extract in real time and ensure the clarity of the extract. However, these devices are only equipped with a single filter element for residue filtration. Under continuous circulating extraction conditions, once the filter element experiences increased resistance and decreased filtration efficiency due to excessive residue retention, the machine needs to be stopped for disassembly, cleaning, or replacement of the filter element. This interrupts the extraction and circulation process, causing long downtime and seriously affecting the overall production efficiency of lotus seed wine brewing, especially making it difficult to adapt to the continuous production requirements of large-scale production. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies have overly simplistic solutions. It mainly provides a lotus ultrasonic circulation extraction device to solve the technical problem mentioned in the background that existing devices require shutdown and cleaning when the single filter component becomes clogged, interrupting production and making it difficult to meet the needs of large-scale continuous production.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An ultrasonic circulation extraction device for lotus flowers includes an extraction tank body with a detachable tank cover on top. A discharge valve is located at the center of the bottom of the extraction tank body, and liquid outlet valves are symmetrically arranged at the bottom of the extraction tank body. The outlet of each liquid outlet valve is connected to a filter assembly via a pipe. The outlets of two filter assemblies are connected to a liquid storage tank. The outlet of the liquid storage tank is connected to the inlet of a delivery pump via a pipe. The outlet of the delivery pump is connected to a reflux port located on the upper side wall of the extraction tank body via a pipe. Multiple ultrasonic modules are evenly distributed circumferentially on the outer side wall of the extraction tank body.

[0006] More preferably, the ultrasonic module includes an external ultrasonic generator and an ultrasonic transducer mounted on the main wall of the extraction tank.

[0007] More preferably, a drive motor is provided at the top center of the can lid, and the output shaft of the drive motor is connected to a stirring shaft that extends into the body of the extraction can.

[0008] More preferably, the outer wall of the extraction tank body is provided with a jacket structure, the jacket structure includes two jacket cavities distributed near the bottom and near the top of the tank body, the two jacket cavities are connected through a cavity in the wall of the extraction tank body, and the jacket structure is provided with a medium inlet and a medium outlet for introducing heat exchange medium.

[0009] More preferably, the filter assembly includes a sealed housing, the outer wall of which is rotatably connected by a hinge to an openable sealing cover, and the outlet valve extends through a pipe through the top of the sealed housing and into its interior.

[0010] More preferably, the filtration assembly further includes a filter element disposed inside the sealed housing, the filter element being a basket filter or a bag filter.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This extraction device, by symmetrically arranging two outlet valves and matching filter components at the bottom of the extraction tank, allows for the cleaning, maintenance, or replacement of filter components with excessive impurities without stopping the entire extraction system. This avoids the downtime caused by filter component cleaning in traditional equipment, ensuring the continuity of the entire extraction, filtration, and circulation process, thereby improving production efficiency. The filter components offer two options: basket filters and bag filters. The basket filters have high mechanical strength and large capacity, suitable for coarse filtration scenarios with high solid content and large particles, and can be repeatedly washed and reused. The bag filters provide higher filtration precision to meet the process requirements of high extract clarity. The two filtration methods can be flexibly selected according to the characteristics of the lotus raw material, the type of extraction solvent, and the requirements of subsequent purification processes, ensuring filtration effects in different scenarios and further broadening the application range of the device.

[0015] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0017] Please refer to the appendix carefully. Figures 1-3 A lotus ultrasonic circulation extraction device includes an extraction tank body 1 and a control system. The top of the extraction tank body 1 is detachably fitted with a tank cover 3. A discharge valve 6 is provided at the center of the bottom of the extraction tank body 1. Liquid outlet valves 7 are symmetrically arranged at the bottom of the extraction tank body 1. The outlet of each liquid outlet valve 7 is connected to a filter assembly 8 through a pipe. The outlets of the two filter assemblies 8 are connected to a liquid storage tank 9. The outlet of the liquid storage tank 9 is connected to the inlet of a delivery pump 2 through a pipe. The outlet of the delivery pump 2 is connected to a return port opened on the upper side wall of the extraction tank body 1 through a pipe. Multiple ultrasonic modules 5 are evenly distributed circumferentially on the outer side wall of the extraction tank body 1.

[0018] The extraction tank body 1 is equipped with a temperature sensor to collect temperature data of the extraction environment inside the tank in real time; the discharge valve 6 and the liquid outlet valve 7 are preferably electric valves, and the temperature sensor, the delivery pump 2, the drive motor 4, the ultrasonic module 5 and the electric valve are all electrically connected to the external control system.

[0019] Through this electrical connection structure, the control system can receive temperature signals from the temperature sensor in real time, and then regulate the circulation status of the heat exchange medium in the jacket structure, such as flow rate and temperature, to achieve closed-loop control of the extraction temperature inside the tank. At the same time, the control system can start and stop the delivery pump 2 and adjust its power, regulate the speed of the drive motor 4, switch the working state of the ultrasonic module 5 and adjust its power, and control the opening and closing timing and opening degree of the electric valve.

[0020] In this embodiment, as Figure 1 As shown, the ultrasonic module 5 includes an external ultrasonic generator and an ultrasonic transducer installed on the wall of the extraction tank body 1.

[0021] The above structure realizes the separate design of ultrasonic generator and transducer. The heat-generating ultrasonic generator is placed externally, which is conducive to heat dissipation and avoids its performance degradation or damage due to the high temperature of the tank. This improves the stability and service life of the equipment and makes the maintenance, repair or replacement of ultrasonic generator more convenient.

[0022] In this embodiment, as Figure 1 As shown, a drive motor 4 is located at the top center of the can lid 3. The output shaft of the drive motor 4 is connected to a stirring shaft that extends into the body of the extraction can 1. The ultrasonic module 5 and the stirring motor 4 adopt an intermittent cooperative working mode to avoid mutual interference between the sound field and the flow field.

[0023] With the above structure, the drive motor 4 drives the stirring blades inside the tank to rotate through the stirring shaft, which can perform strong and uniform mechanical stirring of the material inside the tank during the extraction process, so that solid materials such as lotus fragments are fully mixed with the extraction solvent, preventing material sedimentation, eliminating dead corners in the extraction, and the fluid dynamic field formed by stirring works synergistically with the ultrasonic energy field to break the standing wave effect of ultrasonic waves, making the sound energy distribution more uniform and improving the uniformity of extraction.

[0024] In this embodiment, as Figure 1 As shown, the outer wall of the extraction tank body 1 is provided with a jacket structure. The jacket structure includes two jacket cavities distributed near the bottom and near the top of the tank body. The two jacket cavities are connected through a cavity in the wall of the extraction tank body 1. The jacket structure is provided with a medium inlet and a medium outlet for introducing heat exchange medium.

[0025] With the above structure, the heat exchange medium can circulate in the connected jacket cavity, which can uniformly heat or cool the material in the tank. This can avoid problems such as reduced dissolution efficiency and deterioration of effective components caused by excessively high or low local temperatures, thereby improving the stability of the extraction process.

[0026] It should be noted that the specific manufacturing processes of the heat exchange medium input supply system and the jacket structure in this utility model all adopt existing mature technologies and devices in the field. They are not the core improvement points of this utility model, so their specific structures and working details will not be further described in this application.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the filter assembly 8 includes a sealed housing, the outer wall of which is rotatably connected to an openable sealing cover via a hinge, and the outlet valve 7 passes through the top of the sealed housing and extends into its interior via a pipe.

[0028] The structure described above, with its hinged design between the sealed outer shell and the sealing cover, allows for quick opening and operation when cleaning or replacing internal filter elements is required. After the process is completed, the seal is restored, ensuring that the filtration process takes place in a closed environment, preventing solvent evaporation and contamination, and meeting clean production requirements.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the filter assembly 8 also includes a filter element and a large-aperture support frame disposed inside the sealed housing. The large-aperture support frame is disposed near the bottom inside the sealed housing. The support frame is used to provide stable support for the filter element above. The filter element is a basket filter or a bag filter.

[0030] The above structure provides two optional filtration solutions, enhancing the equipment's adaptability. Basket filters feature high mechanical strength and large sludge capacity, making them suitable for coarse filtration scenarios with high solid content and large particles. They can be repeatedly washed and reused, offering good economic benefits. Bag filters provide higher filtration accuracy and superior filtration performance, suitable for applications requiring high liquid clarity. The most suitable filtration method can be flexibly selected based on different material characteristics and process requirements, broadening the equipment's application range.

[0031] The specific operating procedure of this utility is as follows: The operator opens the tank lid 3, adds the solid material to be extracted, such as lotus flower fragments, and an appropriate amount of extraction solvent into the extraction tank body 1 through the feed port on the tank lid 3, and then seals the feed port.

[0032] Next, a heat exchange medium such as hot water or steam is introduced through the medium inlet of the jacket structure. The temperature sensor inside the tank senses the temperature and heats the material inside the tank to the set temperature, creating the best thermodynamic environment for the extraction process.

[0033] Next, the drive motor 4 is started, driving the stirring shaft and its blades to rotate, thoroughly and evenly stirring the material to prevent solid particles from settling and eliminate extraction dead zones. Simultaneously, the ultrasonic module 5 is activated. An external ultrasonic generator drives an ultrasonic transducer mounted on the tank wall, generating high-frequency mechanical vibrations and radiating powerful ultrasonic waves into the extraction solvent through the tank wall. The cavitation effect generated by the ultrasound can instantly break down plant cell walls, greatly accelerating the diffusion rate of active ingredients into the solvent. The fluid flow created by mechanical stirring disperses any standing wave points that might form with the ultrasound, resulting in a more uniform sound field distribution. The synergistic effect of these two processes improves extraction efficiency and uniformity.

[0034] During operation, one of the outlet valves 7 can be opened while the other is closed. The turbid liquid enters a connected filter assembly 8, such as a sealed housing containing a basket filter. The liquid passes through the filter screen, while solid impurities are trapped inside. The partially clarified liquid then flows into the storage tank 9. At this time, the other outlet valve 7 and its connected filter assembly 8 are in a closed standby state. When the resistance of the operating filter assembly 8 increases due to excessive impurity trapping, it is not necessary to stop the entire extraction system. The operator only needs to switch the on / off state of the outlet valve 7 to switch the main process to the standby filter pipeline to continue operation. Then, the previously used filter assembly 8 can be cleaned by opening its sealing cover, removing the basket filter to clean the residue or replacing the bag filter. After cleaning, the sealing cover is closed for the next switchover. This ensures the continuity and efficiency of production.

[0035] The clarified extract that flows into the storage tank 9 is then pumped by the transfer pump 2 and pumped back into the extraction tank body 1 through the reflux port located at the top of the tank. The refluxed clarified solvent is in continuous contact with the high concentration of material in the tank, maintaining a high mass transfer concentration difference, thereby driving the extraction reaction to continue to the right until the extraction is complete. After the extraction process is completed, the ultrasonic module 5, the drive motor 4 and the transfer pump 2 are turned off, and the final extract can be discharged from the discharge valve 6 of the storage tank 9.

[0036] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
