Description

Technical Field

[0001] This invention relates to the field of anthocyanin extraction technology, and in particular to an apparatus and method for extracting anthocyanins from aralia elata. Background Technology

[0002] Aronia berry, also known as black chokeberry, is the fruit of the black chokeberry plant, belonging to the Rosaceae family. Aronia berries are among the plants with a high content of anthocyanins, a natural antioxidant. The anthocyanin content in aronia berries is 70% in the pulp, 25% in the peel, and 5% in the seeds. The current method of washing aronia berries using water flow requires laying the berries flat to ensure that every part of the berry, whether floating or sinking, is thoroughly cleaned. However, this method has several problems. First, to achieve the desired flat washing effect, the washing space is underutilized, resulting in a large equipment footprint and wasted workshop space. Second, because the washing solution stays on the fruit surface for a short time, it is difficult to effectively remove mud or other contaminants, especially solidified impurities, adhering to the aronia berries. These residual impurities may affect the subsequent anthocyanin extraction process, causing unnecessary problems. Summary of the Invention

[0003] The main objective of this invention is to provide an anthocyanin extraction device for aralia elata, which aims to improve cleaning efficiency and fruit quality, and ensure an efficient and hygienic production environment.

[0004] To achieve the above objectives, the present invention provides an anthocyanin extraction device for sensual berries, comprising: A cleaning shell is provided, with an inlet hopper fixedly connected to the upper side of the cleaning shell and an outlet hopper fixedly connected to the outer wall of one side of the cleaning shell. A water tank is provided between the inlet hopper and the outlet hopper. The water tank is fixedly installed inside the cleaning shell. A water filtration assembly for water circulation filtration of the water tank is provided outside the cleaning shell. The shaking bin slides up and down along the inner wall of the cleaning housing. A hinged, closable flip plate is connected to the lower side of the shaking bin. The outer wall of the shaking bin near the lower side and the flip plate are both meshed. A first cylinder is fixedly connected to the inner wall of the cleaning housing to limit the height of the shaking bin. Several sets of dehumidifying fans are arranged on the inner walls of both sides of the cleaning shell, with the material shaking hopper as the center. A decontamination pipe is installed on the feed hopper.

[0005] In one possible implementation, when the tilting plate is fully closed with the shaking hopper, it is tilted downwards toward the discharge hopper.

[0006] In one possible implementation, a second cylinder is fixedly connected to the side of the shaking bin facing the first cylinder, and a linkage plate is hinged to the side of the shaking bin near the flip plate. The end of the linkage plate near the flip plate is fixedly connected to the flip plate, and a transmission plate is hinged between the telescopic shaft of the second cylinder and the linkage plate.

[0007] In one possible implementation, a feeding plate is provided on the upper edge of the water tank near the discharge hopper, and a torsion spring is provided at the connection point between the feeding plate and the water tank.

[0008] In one possible implementation, a number of locking blocks are fixedly connected to the inner wall of the shaking bin near the upper side. A brush plate is slidably connected between two locking blocks with aligned and parallel slots. Both sides of each brush plate are frosted. A drive shaft controlled by a motor is rotatably connected to the shaking bin. A number of eccentric wheels are fixedly connected to the drive shaft. Adjacent eccentric wheels are not coaxial. The upper side of each brush plate abuts against each adjacent eccentric wheel.

[0009] In one possible implementation, a support block is slidably connected to the inner wall of the cleaning housing, the telescopic shaft of the first cylinder is fixedly connected to the support block, a receiving plate is slidably connected to the support block, the receiving plate is fitted and fixedly connected to the shaking hopper, a receiving disc is rotatably connected to the support block, a non-center point on the receiving disc abuts against the inner wall of the groove on the receiving plate, a drive motor is fixedly connected to the support block, and the drive shaft of the drive motor is fixedly connected to the axis of the receiving disc.

[0010] In one possible implementation, a shaking disc is slidably connected to the support block, and a non-center point on the shaking disc abuts against the inner wall of the longitudinal groove on the outer wall of the shaking bin. A transmission gear is coaxially fixedly connected to the shaking disc, and a positioning rack is fixedly connected to the support block. The transmission gear meshes with the positioning rack.

[0011] In one possible implementation, an electrical control box is fixedly connected to the outer wall of the cleaning housing, and a main control screen is provided on the door panel of the electrical control box.

[0012] This invention, through the coordinated use of multiple components such as a cleaning pipe, a feeding hopper, a shaking hopper, and a tilting plate, effectively improves the cleanliness and production efficiency of the entire cleaning and drying process, offering the following benefits: Water flowing from the holes in the cleaning pipe not only helps the aronia berries slide smoothly down the inclined surface of the feeding hopper but also removes dust and minor debris from the fruit surface, effectively preventing cross-contamination. The mesh structure within the shaking hopper and the buffering effect of the water tank effectively protect the falling berries in the water, preventing mechanical damage during the descent. The water flow at the feeding hopper effectively washes away dust and broken berries from the aronia berry surface, keeping the hopper clean and ensuring that subsequent operations are not affected by dirt, thus ensuring fruit quality. Under the soaking and water flow in the shaking hopper, the solidified dust adhering to the aronia berries is softened and removed. The up-and-down movement of the shaking hopper further promotes the separation of water and fruit, significantly improving the cleaning effect. After the cleaning cycle, the cleaning pipe rinses the fruit again to ensure a thoroughly clean surface. Combined with a dehumidifying fan, the berries are effectively dried, and the clean, dry aronia berries are stably discharged into the discharge hopper via a tilting plate, ensuring the uniformity and stability of the fruit distribution. The design of a buffered water flow and a mesh structure prevents damage to the aronia berries during washing, maintaining their integrity. The separation of water flow and fruit, combined with the up-and-down movement of the shaking hopper, removes solidified dust while minimizing fruit damage. The drying process, in conjunction with the tilting plate, ensures the stability and uniformity of fruit discharge, preventing uneven humidity or breakage, thus ensuring uninterrupted subsequent processing. Overall, the multi-processing technology, including water washing, dust softening, and fruit drying, effectively improves production efficiency, reduces the need for manual intervention, maintains a hygienic environment, avoids cross-contamination, and minimizes fruit damage, ensuring high quality and stable output for each batch of aronia berries.

[0013] Another objective of this invention is to provide a method for extracting anthocyanins from aralia elata, which aims to ensure the cleanliness and stability of the fruit, laying a good foundation for subsequent extraction work.

[0014] To achieve the above objectives, the present invention proposes a method for extracting anthocyanins from aralia elata, comprising: S1. Raw material selection: Select ripe and fresh arugula fruits, ensuring that the surface is plump and free from pests and diseases. Then select the extraction solvent. Finally, prepare filter paper, beaker, glass rod, centrifuge, and vacuum filtration device. S2. Pre-treatment: The aronia berries are fed into the shaking hopper along the feed hopper and washed with water. After washing, the berries are moved through the discharge hopper to the crusher for crushing and making into a slurry. S3. Extraction: Place the crushed fruit pulp into the extraction solvent and soak it. Use a magnetic stirrer or ultrasonic treatment equipment to help accelerate the extraction process. S4. Filtration and separation: The extracted liquid is filtered through filter paper to remove fruit residue, resulting in a turbid solution containing anthocyanins. The supernatant containing anthocyanins is then extracted using a centrifuge. S5. Concentration: The solvent in the extract is removed by vacuum concentration or low temperature concentration equipment to obtain a concentrated solution; S6. Drying: The concentrated anthocyanin solution is spray-dried or freeze-dried to obtain anthocyanin powder, thus completing the extraction of anthocyanins.

[0015] In one possible implementation, in S2, the preprocessing includes: A1. Soaking: Drive the shaking bin downwards so that the lower part of the shaking bin is placed in the water tank. Then, put a measured amount of unwashed arugula into the feeding bin. The arugula slides into the shaking bin through the cooperation of the upper inclined surface of the feeding bin and the cleaning pipe, and falls into the water tank for soaking. A2. Initial Wash: The first cylinder drives the shaking bin to move up and down repeatedly. Through the relative movement between the shaking bin and the water tank, the water flow further cleans the aralia elata. A3. Fine washing: After the initial washing, suspend the shaking bin in the water tank and stop. Then, rinse the surface of the aronia berries at the end of the cleaning pipe to separate the dirty water that is still condensed on the surface of the aronia berries from the fruit due to tension. A4. Draining: After the initial washing, the berries are dried using several sets of dehumidifying fans set around the shaking hopper.

[0016] Another technical solution of this invention effectively extracts anthocyanins from age berries through precise multi-stage processing, with each stage designed rationally and scientifically. Particularly in the pretreatment stage, processes such as soaking, initial washing, fine washing, and draining ensure the cleanliness and stability of the fruit, laying a solid foundation for subsequent extraction. Simultaneously, the application of modern technologies such as ultrasonic-assisted extraction and centrifugation makes anthocyanin extraction more efficient and precise. Through concentration and drying steps, high-purity anthocyanin powder is finally obtained, possessing high commercial value and application potential. Attached Figure Description

[0020] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Example 1

[0023] This invention proposes a device for extracting anthocyanins from aralia elata; Reference Figures 1 to 7 In this embodiment of the invention, the aralia elata anthocyanin extraction device includes a cleaning shell 11, a shaking hopper 16, a decontamination pipe 110, and several sets of dehumidifying fans 19.

[0024] The feeding hopper 12 is fixedly connected to the upper side of the cleaning housing 11. The outer wall of one side of the cleaning housing 11 is fixedly connected to the discharging hopper 13. The water tank 14 is located between the feeding hopper 12 and the discharging hopper 13 and is fixedly installed inside the cleaning housing 11. The water filter assembly 15 for water circulation filtration of the water tank 14 is located outside the cleaning housing 11. The shaking hopper 16 slides up and down along the inner wall of the cleaning housing 11. The openable and closable flip plate 17 is hinged to the lower side of the shaking hopper 16. The outer wall of the shaking hopper 16 near the lower side and the flip plate 17 are both grid-like. The first cylinder 18 for limiting the height of the shaking hopper 16 is fixedly connected to the inner wall of the cleaning housing 11. Each set of dehumidifying fans 19 is arranged on the inner walls of both sides of the cleaning housing 11 with the shaking hopper 16 as the center. The dirt removal pipe 110 is installed on the feeding hopper 12.

[0025] Water flowing through several holes in the drain pipe 110 guides the aronia berries down the slope of the feed hopper 12 into the shaking hopper 16. During this process, the water flow not only guides the aronia berries as they slide down but also helps remove dust and some light debris from their surface. The shaking hopper 16 is located inside the water tank 14 and its mesh structure cushions the falling fruit in the water, thus preventing damage to the aronia berries during their descent.

[0026] In addition, at the feed hopper 12, the water flow can effectively wash away dust and broken aronia berries, preventing dirt from accumulating in the feed hopper 12 and ensuring its cleanliness, thus avoiding cross-contamination in subsequent operations. After the aronia berries fall into the shaking hopper 16, they are thoroughly soaked. As the shaking hopper 16 moves, it helps the water flow into the gaps between the berries, thereby softening and removing the solidified dust adhering to the surface of the berries. The separation of the water flow from the aronia berries further enhances the cleaning effect.

[0027] After the cleaning cycle is completed, the shaking hopper 16 stops rising, and the decontamination pipe 110 will rinse the aronia berries again to ensure that their surface is thoroughly clean. Then, with the cooperation of several sets of dehumidifying fans 19, the fruit is dried as much as possible, and finally, the clean and dry aronia berries are stably discharged into the discharge hopper 13 by opening the flip plate 17.

[0028] In summary, through multiple processes including water washing, dust softening, and fruit drying, the production line was kept clean and hygienic, ensuring consistent output quality for each batch of aronia berries, preventing cross-contamination, and minimizing damage to the berries. This effectively improved the efficiency and fruit quality of the entire production process, reduced the need for manual intervention and errors, and ensured a highly efficient and hygienic production environment.

[0029] Furthermore, the buffered water flow and mesh structure prevent damage to the arugula during the washing process, keeping the fruit intact. The separation of water flow from the fruit, combined with the up-and-down movement of the shaking chamber 16, thoroughly cleans the solidified dust on the fruit surface, improving the washing effect while reducing damage.

[0030] In addition, the drying process, in conjunction with the flipping plate 17, ensures the stability and uniformity of the fruit during discharge, thereby avoiding uneven humidity or damage that could affect subsequent processing.

[0031] refer to Figure 4 When the tilting plate 17 and the shaking hopper 16 are fully closed, it is tilted downwards towards the discharge hopper 13.

[0032] After the perennial berries in the shaking bin 16 have finished washing, the flipping plate 17 can easily discharge them from the bin 16 by simply flipping at a small angle. The small flipping angle of the flipping plate 17 means that the stroke of the drive component driving the flipping plate 17 can be significantly shortened. This not only reduces the energy consumption and cost of the drive system but also reduces the size requirements of the drive component, making the system more compact and efficient.

[0033] Furthermore, the material can be automatically discharged along the inclined surface under its own weight, ensuring the output of the material.

[0034] Furthermore, the design of the flip plate 17 offers additional advantages. Due to the smaller flip angle, more area on the outer surface of the shaker 16 can be freed up for the mesh setting, thereby enhancing the interaction between the shaker 16 and the water flow in the water tank 14. The water flow, passing through the mesh structure of the shaker 16, makes full contact with the aristocrat, further improving cleaning efficiency while enhancing the cleaning and softening effects of the water, ensuring that the aristocrat surface is thoroughly cleaned.

[0035] This not only improves the reliability and stability of the system, but also further enhances the efficiency of the production process and reduces the maintenance cost of the equipment by simplifying the drive mechanism and enhancing the cleaning effect of the water flow.

[0036] refer to Figures 6 to 7 The shaking bin 16 is fixedly connected to the second cylinder 21 on the side facing the first cylinder 18. The shaking bin 16 is hinged to the linkage plate 22 on the side near the tilting plate 17. The end of the linkage plate 22 near the tilting plate 17 is fixedly connected to the tilting plate 17. The transmission plate 23 is hinged between the telescopic shaft of the second cylinder 21 and the linkage plate 22.

[0037] The opening and closing of the flip plate 17 can be precisely controlled by the second cylinder 21. When the flip plate 17 is closed, the shaking chamber 16 moves up and down, ensuring that the aronia berries remain inside the shaking chamber 16 during the washing process and do not fall out, thus effectively completing the washing. The closing of the flip plate 17 not only provides restraint for the fruit but also enhances the washing effect through the contact between the water flow and the fruit, ensuring that attached impurities and dust are removed from the surface of the aronia berries.

[0038] During discharge, the discharge speed of the aronia berries can be controlled by adjusting the opening angle of the flip plate 17. This makes it possible to process different batches of aronia berries, and the discharge speed can be flexibly adjusted according to the actual situation, thereby ensuring a stable discharge effect for each batch of fruit and avoiding the impact on the overall cleaning and discharge quality due to excessively fast or slow speeds.

[0039] Furthermore, controlling the opening and closing angle of the flipping plate 17 effectively reduces the impact between the arugula and the flipping plate, lowering the risk of surface damage. This is crucial for maintaining the integrity of the fruit, especially in large-scale processing, ensuring a low damage rate throughout the process and maximizing the preservation of freshness and appearance quality. Overall, this control method improves the system's flexibility and stability, ensuring high efficiency and low loss in processes such as washing and discharging.

[0040] refer to Figures 3 to 4 The feeding plate 24 is located on the upper edge of the water tank 14 near the discharge hopper 13, and a torsion spring is provided at the connection between the feeding plate 24 and the water tank 14.

[0041] Through the ingenious design of the torsion spring, the feeding plate 24 naturally tilts towards the discharge bin 13 when no external force is applied, ensuring that the feeding plate always maintains an appropriate tilt angle. When the tilting plate 17 is opened, the washed berries will slide down onto the feeding plate 24, controlled by the angle of the tilting plate 17. The tilted design of the feeding plate 24 helps the berries smoothly enter the next process from the discharge bin 13 for crushing.

[0042] By reducing the gap between the flipping plate 17 and the feeding plate 24, the perennial berries can pass through the discharge hopper 13 more smoothly, reducing jamming or obstruction and ensuring the stability and efficiency of the entire discharge process. Furthermore, the elasticity of the torsion spring provides cushioning for the entire process. Specifically, when the feeding plate 24 is subjected to the weight of the perennial berries, the torsion spring can absorb a certain amount of impact force, preventing the perennial berries from being damaged due to rapid falling and ensuring the integrity and quality of the fruit.

[0043] Furthermore, the torsion spring causes the shaking bin 16 to move downwards as a whole, thereby generating a driving force on the feeding plate 24, which in turn causes the feeding plate 24 to rotate. This action, in conjunction with the soaking operation of the shaking bin 16, ensures that the berries can smoothly transition to the next process after cleaning, while improving the system's smoothness and efficiency.

[0044] In summary, the combination of the feeding plate 24, the torsion spring, and the flipping plate 17 not only improves the accuracy of material discharge by reducing the gap, but also reduces surface damage to the berries through the buffering effect of the torsion spring, while maintaining the efficiency and stability of the entire cleaning and discharging process.

[0045] refer to Figures 1 to 2 The electrical control box 51 is fixedly connected to the outer wall of the cleaning housing 11, and the main control screen 52 is fixedly connected to the door panel of the electrical control box 51.

[0046] Firstly, the design of the electrical control box 51 fixedly connected to the outer wall of the cleaning housing 11 allows the electrical control box 51 to be directly connected to the external environment of the equipment. This not only helps to enhance the stability of the electrical control box 51 and prevent damage from external vibrations or impacts, but also optimizes the layout of the internal space of the equipment, making it more compact. During equipment cleaning and maintenance, operators can easily access the electrical control box, reducing operational difficulty and improving maintenance efficiency. Then, through the main control screen 52, the operation of various components inside the cleaning housing 11, such as the water filter assembly 15 and the shaking hopper 16, as well as several sets of dehumidifying fans 19, can be controlled. This provides operators with an intuitive and convenient control interface, allowing them to monitor the equipment's operating status in real time and adjust various parameters, avoiding the inconvenience of frequently opening the electrical control box. This improves the convenience and intuitiveness of operation, enabling operators to easily check the equipment status and make adjustments at any time, effectively reducing the risk of operational errors, and also facilitating the maintenance of internal components.

[0047] Example 2

[0048] This embodiment expands upon the cleaning effect of the shaking hopper 16 based on Embodiment 1; refer to Figures 1 to 7 The support block 41 is slidably connected to the inner wall of the cleaning housing 11. The telescopic shaft of the first cylinder 18 is fixedly connected to the support block 41. The receiving plate 42 is slidably connected to the support block 41. The receiving plate 42 is fitted and fixedly connected to the shaking bin 16. The receiving plate 43 is rotatably connected to the support block 41. The non-center point on the receiving plate 43 abuts against the inner wall of the groove on the receiving plate 42. The support block 41 is fixedly connected to the drive motor 44. The drive shaft of the drive motor 44 is fixedly connected to the axis of the receiving plate 43.

[0049] The support block 41 is fixedly connected to the telescopic shaft of the first cylinder 18. The telescopic movement of the first cylinder 18 precisely drives the movement of the support block 41, thereby achieving precise control and adjustment of the relative position of the shaking bin 16. This allows the support block 41 to be precisely positioned according to requirements at different working stages, greatly improving the stability and operational accuracy of the equipment.

[0050] Furthermore, the drive motor 44 drives the receiving plate 43, whose non-center point cooperates with the slot on the receiving plate 42, ensuring that the receiving plate 42 can move up and down along the high side of the support block 41 when the receiving plate rotates. This enables the shaking bin 16 to achieve short-distance up and down shaking, producing good technical effects whether it is in the water tank 14 or suspended above the water tank 14.

[0051] In water tank 14: When the shaking bin 16 is in water tank 14, the up-and-down shaking can effectively increase the impact force of the water flow through the aralia, promoting the impact and disintegration of solidified impurities on the aralia surface. This vibration not only accelerates the decomposition of solidified substances, but also carries these impurities into the water tank with the water flow, thereby improving the cleaning effect of the aralia and ensuring the thorough removal of surface impurities.

[0052] When suspended above water tank 14: When the shaking hopper 16 is suspended, some moisture may remain inside. Normally, due to surface tension, this moisture slowly seeps or falls. The mechanical action of shaking up and down breaks this surface tension, allowing the moisture to drain more quickly. At this time, combined with several sets of dehumidifying fans 19, the drying speed of the arugula is further accelerated, effectively shortening the transition time from washing to drying.

[0053] This not only improves cleaning efficiency but also reduces residual moisture, increasing the dryness of the aronia berries before they enter the crusher. This, in turn, lowers the water content in the extraction solution during crushing, further increasing the anthocyanin concentration. This ensures optimal processing of the aronia berries, optimizing both the cleaning and drying processes and enhancing the efficiency of subsequent crushing and extraction stages.

[0054] Example 3

[0055] This embodiment further expands the cleaning effect of the shaking hopper 16 based on embodiment 2. refer to Figures 1 to 7 The shaking disc 45 is slidably connected to the support block 41. The non-center point on the shaking disc 45 abuts against the inner wall of the longitudinal groove on the outer wall of the shaking bin 16. The shaking disc 45 is coaxially and fixedly connected to the transmission gear 46. The positioning rack 47 is fixedly connected to the support block 41. The transmission gear 46 meshes with the positioning rack 47.

[0056] Based on the original up-and-down movement of the shaking bin 16, further improvements have been made to enable the shaking bin 16 to rotate around the axis of the receiving plate 42 while moving up and down. Specifically, when the shaking bin 16 moves up and down, the support block 41 and the shaking bin 16 are engaged by sliding. During this process, the meshing of the positioning rack 47 and the transmission gear 46 drives the rotation of the shaking disc 45.

[0057] The non-center point on the shaking disc 45 forms contact with the inner wall of the longitudinal groove on the outer wall of the shaking bin 16, allowing the shaking bin 16 to sway left and right as the shaking disc 45 rotates. This swaying motion adds left and right swinging to the up-and-down shaking of the shaking bin 16, repeatedly changing the relative position of the lowest side of the shaking bin 16.

[0058] This improved design plays a crucial role in the soaking of the aurantiacus. When the shaking chamber 16 is suspended above the water tank 14, the aurantiacus rolls inside as the shaking chamber 16 swings left and right, further accelerating the breakdown of water surface tension and promoting water drainage. This not only reduces residual water but also allows water to drain from the shaking chamber 16 more quickly.

[0059] Furthermore, this oscillating design significantly improves the drying speed of aronia berries. By accelerating water drainage and reducing water adsorption on the aronia berries, combined with the dehumidifying fan 19, the overall drying efficiency of the washed aronia berries is improved, ensuring that the aronia berries can quickly enter the subsequent crushing and extraction processes, further increasing the concentration of anthocyanins in the extraction solution.

[0060] Example 4

[0061] This embodiment adds a scrubbing effect based on embodiment 1; refer to Figures 1 to 7 Several locking blocks 31 are fixedly connected to the inner wall of the shaking bin 16 near the upper side. Each brushing plate 32 is slidably connected between two locking blocks 31 with aligned and parallel slots. Both sides of each brushing plate 32 are frosted surfaces 33. The drive shaft 34, controlled by a motor, is rotatably connected to the shaking bin 16. Several eccentric wheels 35 are fixedly connected to the drive shaft 34. Adjacent eccentric wheels 35 are not coaxial. The upper side of each brushing plate 32 abuts against each adjacent eccentric wheel 35.

[0062] Through the design of several washing plates 32, the internal space of the shaking bin 16 is effectively divided into multiple areas. These areas are controlled by a drive shaft 34 driven by a motor to move adjacent washing plates 32 up and down. During the movement, adjacent washing plates 32 move up and down through contact with eccentric wheels 35. In this way, the berries that fall into different areas will be surface-washed by the abrasive surface 33 on the washing plates 32.

[0063] Furthermore, the setting of the washing plate 32 can be adjusted as needed. For example, it can be divided into multiple equal areas, or different areas can be set according to the size of the fruit, arranged from smallest to largest. This setting allows for more effective and refined processing of fruits of different sizes. To ensure that the fruits are classified by size and enter the corresponding areas, a screening machine can be installed at the feed hopper 12. The screening machine diverts fruits of different sizes to the corresponding areas, thereby ensuring that each type of fruit receives the best cleaning effect during the washing process.

[0064] This process not only improves the scrubbing effect on the fruit surface but also better removes impurities from the surface of the arugula, further enhancing the overall cleaning efficiency and quality. This meticulous cleaning process ensures that there are no residues on the fruit surface, maintaining the fruit's freshness and quality, and providing better raw materials for subsequent processing or packaging.

[0065] Example 5

[0066] This embodiment is a further improvement on embodiment 4; refer to Figures 1 to 7 The gap between the two parallel slotted blocks 31 is greater than the width of the brush plate 32.

[0067] The clearance allows for easier disassembly and installation of the scrubbing plate 32. Operators can more easily remove or replace the scrubbing plate 32, significantly improving work efficiency during routine maintenance and cleaning. Furthermore, this clearance allows the scrubbing plate 32 to move not only vertically but also horizontally. This additional sliding direction allows the scrubbing plate to adapt more flexibly to different work needs and environments, further improving the flexibility and effectiveness of scrubbing. When berries fall into different areas, the lateral offset of the scrubbing plate 32 ensures that the berry surface makes more even and comprehensive contact with the abrasive surface 33, resulting in a more thorough scrubbing of the fruit surface. Especially with irregularly shaped berries or when berries are densely packed, the multi-directional movement of the scrubbing plate ensures that all berries receive uniform and effective scrubbing.

[0068] Example 6

[0069] This invention also proposes a method for extracting anthocyanins from aralia elata, referring to... Figures 1 to 7 include: S1. Raw material selection: Select ripe and fresh arugula fruits, ensuring that the surface is plump and free from pests and diseases. Then select the extraction solvent. Finally, prepare filter paper, beaker, glass rod, centrifuge, and vacuum filtration device. Ensuring the fruit surface is plump and free of pests and diseases is fundamental to guaranteeing the quality of the final extract. Choosing a suitable solvent ensures efficient dissolution and extraction of anthocyanins. S2.

[0070] refer to Figure 5 In S2, preprocessing includes: A1. Soaking: Drive the shaking bin 16 downwards so that the lower area of ​​the shaking bin 16 is placed in the water tank 14. Then, put a measured amount of unwashed arugula into the feeding bin 12. The arugula slides into the shaking bin 16 through the cooperation of the upper inclined surface of the feeding bin 12 and the cleaning pipe 110, and falls into the water tank 14 for soaking. The shaking hopper 16 is driven downwards so that its lower area is placed in the water tank 14. A measured quantity of unwashed arugula is then placed into the feeding hopper 12. With the help of the upper inclined surface of the feeding hopper 12 and the cleaning pipe 110, the fruit slides into the shaking hopper 16 and falls into the water tank for soaking. This step removes impurities and dirt from the fruit surface. During soaking, some of the solidified dirt adhering to the fruit surface is softened by the water, allowing for better removal of this dirt. A2. Initial washing: The first cylinder 18 drives the shaking chamber 16 to move up and down repeatedly. Through the relative movement between the shaking chamber 16 and the water tank 14, the water flow further cleans the aralia. The first cylinder 18 drives the shaking chamber 16 to move up and down repeatedly. Through the relative movement between the shaking chamber 16 and the water tank 14, the water flow further cleans the surface of the arugula, removes more impurities, ensures the cleanliness of the fruit, and makes the softened dirt more easily separated from the surface of the fruit by the impact of the water flow, thereby improving the cleaning effect on the surface of the fruit. A3. Fine washing: After the initial washing, the shaking bin 16 is suspended in the water tank 14 and then stopped. Finally, the surface of the aronia berries is rinsed through the cleaning pipe 110 to separate the dirty water that is still condensed on the surface of the aronia berries due to tension from the fruit. After the initial washing, the arugula is separated into the shaking bin 16 and the water tank 14, and then suspended on the upper side of the water tank. The water flowing out of the cleaning pipe 110 completes the fine washing, making the surface of the fruit completely clean. A4. Draining: After fine washing, the berries are dried by several sets of dehumidifying fans 19 set around the shaking hopper 16. Several sets of dehumidifying fans 19 were used to dry the fruit to remove excess moisture and avoid unnecessary impact on subsequent steps. This method effectively extracts anthocyanins from age berries through precise multi-stage processing, with each step designed rationally and scientifically. Particularly in the pretreatment stage, processes such as soaking, initial washing, fine washing, and draining ensure the cleanliness and stability of the fruit, laying a solid foundation for subsequent extraction. Simultaneously, the application of modern technologies such as ultrasonic-assisted extraction and centrifugation makes anthocyanin extraction more efficient and precise. Through concentration and drying, high-purity anthocyanin powder is finally obtained, possessing significant commercial value and application potential.
