Description

A high-efficiency extraction device for mango peel polyphenols Technical Field

[0001] This invention relates to a polyphenol extraction apparatus, specifically a high-efficiency extraction apparatus for mango peel polyphenols. Background Technology

[0002] Mango is a tropical evergreen tree belonging to the Anacardiaceae family and the Mangifera genus, native to tropical and subtropical regions. The fruit is rich in nutrients, with a sugar content as high as 12%-20%, protein 5.56%, and carbohydrates 67.29%. It also contains abundant vitamins A, B, and C, with vitamin A being the most abundant. In addition, it contains small amounts of calcium, phosphorus, iron, and other minerals. Mangoes are suitable for both fresh consumption and processing, satisfying consumers' diverse fruit needs. However, the byproducts of mangoes—mango peel and pit (accounting for 20%-40% of the total weight, and containing over 90% of the polyphenols in the fruit)—cause both environmental pollution and resource waste. Research has found that mango peel contains polyphenolic compounds such as gallic acid, tannins, quercetin, isoquercitrin, and mangiferin. These compounds possess biological functions such as scavenging free radicals, resisting lipid oxidation, delaying aging, preventing cancer, and resisting radiation.

[0003] Existing extraction methods mainly include solvent extraction, ultrasonic extraction, microwave extraction, and supercritical fluid extraction. Among these, ultrasonic extraction is commonly used in the extraction of various plants. It utilizes the mechanical, cavitation, and thermal effects of ultrasound to increase the velocity of molecules and the penetrating power of the medium, thereby extracting the active ingredients of the organism. Before extraction, the target material (e.g., mango peel) needs to be crushed and then poured into the extraction solution. The extractant and the target material are ultrasonically vibrated in the extraction tank using an ultrasonic module. Polyphenols can be separated and extracted, existing in a free state in the extractant. Subsequently, the polyphenol extract is discharged from the extraction tank. However, separating the waste residue from the polyphenol extract is inconvenient, and removing the waste residue is also difficult, causing inconvenience to the staff, affecting the extraction progress, and requiring improvement in efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a high-efficiency extraction device for mango peel polyphenols. This high-efficiency extraction device can automatically separate the waste residue and polyphenol extract after extraction without manual intervention, which is beneficial to improving work efficiency.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A high-efficiency extraction device for mango peel polyphenols includes an extraction tank, an ultrasonic mechanism, a waste residue separation mechanism, and a waste residue collection mechanism.

[0007] The extraction tank is equipped with an inlet and an outlet.

[0008] The ultrasonic mechanism includes an ultrasonic vibrator and an ultrasonic lifting drive mechanism for driving the ultrasonic vibrator to rise and fall.

[0009] The waste residue separation mechanism includes a waste residue separation net, a waste residue feeding assembly, and an inward and outward flipping drive mechanism for driving the waste residue separation net to flip vertically inward and outward. The main body of the waste residue separation net is located in the inner cavity of the extraction tank, and the opening of the waste residue separation net covers the top of the extraction tank. The waste residue feeding assembly includes an inner limiting cylinder, an outer limiting cylinder, and a spiral feeding guide plate. The inner limiting cylinder is located on the outside of the extraction tank, and its top is lower than or level with the top of the extraction tank. The outer limiting cylinder is located outside the inner limiting cylinder, and its top is higher than the top of the upward-flipping waste residue separation net. The spiral feeding guide plate is fixedly located between the inner and outer limiting cylinders. The inward and outward flipping drive mechanism acts on the bottom of the inner cavity of the waste residue separation net to drive the bottom of the waste residue separation net to move vertically.

[0010] The waste collection mechanism is located below the bottom of the spiral feed guide plate and is used to collect the falling waste.

[0011] In a preferred embodiment of the present invention, the opening of the waste separation net is a flexible structure without holes. After the opening of the waste separation net covers the top of the extraction tank, it bends downward and connects to the first anti-stretching connection structure.

[0012] Furthermore, the first anti-stretch connection structure is provided in at least two sets and is circumferentially distributed around the center of the extraction tank. Each set of the first anti-stretch connection structure includes a first anti-stretch mounting base, an anti-stretch rope, and a first anti-stretch spring. The first anti-stretch mounting base is fixedly installed on the outer bottom of the extraction tank. One end of the anti-stretch rope is fixedly connected to the opening of the waste separation net bag, and the other end of the anti-stretch rope can be movably passed through the first anti-stretch mounting base. The first anti-stretch spring is sleeved on the other end of the anti-stretch rope, and the upper and lower ends of the first anti-stretch spring abut against the first anti-stretch mounting base and the other end of the anti-stretch rope, respectively. In practice, when the waste separation net is pulled upwards and flipped over, most of the waste can be pushed down. However, because the waste is wet, some may stick to the net. Therefore, the net needs to be quickly lifted, and at the top, it should be slightly pulled upwards. The net's elasticity helps to bounce the sticky waste away, thus removing most of the waste – a very practical solution. However, frequent pulling can cause irreversible damage to the net, shortening its lifespan. This preferred solution solves this problem. When the net is pulled upwards, the anti-stretch rope also moves upwards. The first anti-stretch spring is compressed by the rope, transferring the force to the spring and providing cushioning to prevent damage and extend its lifespan – a clever design!

[0013] Furthermore, the first anti-stretch connection structure is located between the outer wall of the extraction tank and the inner wall of the inner limiting cylinder, preventing waste residue from contacting the first anti-stretch connection structure. This allows for more thorough removal of waste residue and also protects the first anti-stretch connection structure from contamination by wet waste residue.

[0014] In a preferred embodiment of the present invention, the spiral feeding guide plate has fewer than 0.5 spiral turns; two spiral feeding guide plates are provided and symmetrically arranged between the inner limiting cylinder and the outer limiting cylinder. This can shorten the time for waste residue to slide down and prevent the accumulation of waste residue.

[0015] In a preferred embodiment of the present invention, the inward and outward tilting drive mechanism includes an inward and outward tilting connecting rod, an inward and outward tilting drive motor, and an inward and outward tilting transmission assembly. The inward and outward tilting transmission assembly includes an inward and outward tilting transmission plate, a gear and rack integrated structure, and a synchronous shaft. Two gear and rack integrated structures are provided, and the synchronous shaft is power-connected between the two gear and rack integrated structures. The inward and outward tilting transmission plate is fixedly installed between the two gear and rack integrated structures. The inward and outward tilting drive motor is connected to one of the gear and rack integrated structures. The upper end of the inward and outward tilting connecting rod is directly or indirectly connected to the inward and outward tilting transmission plate, and the lower end of the connecting rod is fixedly connected to the bottom of the waste separation net. With this structure, driven by the inward and outward tilting drive motor, the gear and rack integrated structure moves vertically along with the inward and outward tilting transmission plate, thereby pulling the bottom of the waste separation net up and down, achieving fully automated operation and saving manpower and resources.

[0016] Furthermore, the upper end of the inward and outward turning connecting rod is connected to the inward and outward turning transmission plate through a second anti-stretching connecting structure. The second anti-stretching connecting structure includes a second anti-stretching mounting base and a second anti-stretching spring. The second anti-stretching mounting base is fixedly installed below the inward and outward turning transmission plate, and the second anti-stretching mounting base is provided with a bidirectional anti-stretching mounting slot. The upper end of the inward and outward turning connecting rod extends into the bidirectional anti-stretching mounting slot, and the upper end of the inward and outward turning connecting rod is provided with a relatively large limiting part. The second anti-stretching spring includes a second upper anti-stretching spring and a second lower anti-stretching spring. The second upper anti-stretching spring and the second lower anti-stretching spring are both sleeved on the upper end of the inward and outward turning connecting rod. The upper and lower ends of the second upper anti-stretching spring respectively abut against the upper bottom surface of the bidirectional anti-stretching mounting slot and the limiting part, and the upper and lower ends of the second lower anti-stretching spring respectively abut against the limiting part and the lower bottom surface of the bidirectional anti-stretching mounting slot.

[0017] During extraction, the inward and outward turning drive mechanism repeatedly performs a stirring and agitation operation. This stirring and agitation operation is as follows: the inward and outward turning drive mechanism first pulls the waste residue separation net upward to a critical height, which is set according to the actual situation, with the rule that the mango peel should not be exposed above the water surface; the inward and outward turning drive mechanism then pulls the waste residue separation net downward. When the waste residue separation net moves to the lowest position, it is elastically stretched, which ejects the mango peel near the surface of the waste residue separation net towards the center of the extraction tank, increasing the movement speed of the mango peel. In this way, the repeated up-and-down stirring and agitation of the mango peel during the extraction process can effectively accelerate the extraction speed and increase the polyphenol yield. Furthermore, because the upper end of the inward and outward flipping connecting rod is held in place by the second upper anti-stretch spring and the second lower anti-stretch spring, when the inward and outward flipping drive mechanism pulls the waste residue separation net bag down to the lowest position, it will continue to pull the waste residue separation net bag down a short distance, causing the waste residue separation net bag to elastically stretch, thereby pushing the mango peel inward and increasing the range and speed of the mango peel's movement in the extraction tank. During this process, the second anti-stretch mounting base compresses the second upper anti-stretch spring downward, and the second upper anti-stretch spring adaptively transmits the power to the inward and outward flipping connecting rod, so that the inward and outward flipping connecting rod gently pulls the waste residue separation net bag down, which can both bounce the mango peel away and not damage the waste residue separation net bag, thus achieving a second layer of protection. In addition, when cleaning waste residue, the waste residue separation net needs to be lifted quickly. Upon reaching the top, the net will be slightly pulled upwards. At this time, the second anti-stretch mounting base compresses the second lower anti-stretch spring, causing the second upper anti-stretch spring to deform and transmit power to the inward and outward flipping connecting rods. This prevents the waste residue separation net from being pulled forcefully, achieving double protection and further improving its service life. Furthermore, the ultrasonic lifting drive mechanism is composed of the inward and outward flipping drive mechanism, with the ultrasonic vibrator mounted on the inward and outward flipping transmission plate. This allows for simultaneous lifting and lowering along with the waste residue separation net, simplifying the structure and reducing costs.

[0018] Furthermore, the top of the outer limiting cylinder is provided with two clearance holes for avoiding the lifting and lowering of the inward and outward turning transmission plates and the synchronous shaft.

[0019] Furthermore, two sealing side plates are provided below the inward and outward turning transmission plate, and the two sealing side plates are respectively located outside the two clearance holes;

[0020] The width of the sealing side plate is greater than or equal to the width of the clearance hole, and the height of the sealing side plate is greater than the height of the clearance hole. This structure allows for vertical movement of the inward and outward turning transmission plates and the synchronous shaft without interference, while simultaneously sealing the clearance hole to prevent mango peel waste from flying out of the outer limiting cylinder.

[0021] In a preferred embodiment of the present invention, the waste collection mechanism includes a waste collection box and a guide component, which is located below the bottom of the spiral feeding guide plate.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. The high-efficiency extraction device of the present invention can automatically separate the waste residue and polyphenol extract after extraction without manual intervention, which is conducive to improving work efficiency.

[0024] 2. By setting up a waste residue separation net and an inward and outward flipping drive mechanism, not only can the mango peel be caught to prevent the mango peel waste from being discharged along with the polyphenol extract, but the waste residue separation net can also be driven to flip upward and outward to unload the waste residue, automatically completing the separation operation, which is very convenient and efficient.

Detailed Implementation

[0033] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0034] Referring to Figures 1-5, the high-efficiency mango peel polyphenol extraction device of this embodiment includes an extraction tank 1, an ultrasonic mechanism, a waste residue separation mechanism, and a waste residue collection mechanism. The extraction tank 1 is provided with an inlet and an outlet. The inlet is connected to an inlet pipe 2, and the outlet is connected to a storage tank 3 through a pipe. The ultrasonic mechanism includes an ultrasonic vibrator 4 and an ultrasonic lifting drive mechanism for driving the ultrasonic vibrator 4 to move up and down.

[0035] Referring to Figures 1-5, the waste residue separation mechanism includes a waste residue separation net 5, a waste residue feeding assembly, and an inward and outward flipping drive mechanism for driving the waste residue separation net 5 to flip vertically inward and outward. The main body of the waste residue separation net 5 is located in the inner cavity of the extraction tank 1, and the opening of the waste residue separation net 5 covers the top of the extraction tank 1. The waste residue feeding assembly includes an inner limiting cylinder 6, an outer limiting cylinder 7, and a spiral feeding guide plate 8. The inner limiting cylinder 6 is disposed in the extraction tank 1. On the outside, the top of the inner limiting cylinder 6 is lower than or level with the top of the extraction tank 1; the outer limiting cylinder 7 is located outside the inner limiting cylinder 6, and the top of the outer limiting cylinder 7 is higher than the top of the upward-turned waste residue separation net 5; the spiral feeding guide plate 8 is fixedly located between the inner limiting cylinder 6 and the outer limiting cylinder 7; the inward and outward turning driving mechanism acts on the bottom of the inner cavity of the waste residue separation net 5 to drive the bottom of the waste residue separation net 5 to move vertically.

[0036] Referring to Figures 1-5, the opening of the waste separation net 5 is a flexible structure without holes. After the opening of the waste separation net 5 covers the top of the extraction tank 1, it bends downward and connects to the first anti-stretching connection structure.

[0037] Referring to Figures 4-6, the first anti-stretch connection structure has at least two sets and is circumferentially distributed around the center of the extraction tank 1. Each set of the first anti-stretch connection structure includes a first anti-stretch mounting base 9, an anti-stretch rope 10, and a first anti-stretch spring 11. The first anti-stretch mounting base 9 is fixedly installed on the outer bottom of the extraction tank 1. One end of the anti-stretch rope 10 is fixedly connected to the opening of the waste residue separation net bag 5, and the other end of the anti-stretch rope 10 can be movably passed through the first anti-stretch mounting base 9. The first anti-stretch spring 11 is sleeved on the other end of the anti-stretch rope 10, and the upper and lower ends of the first anti-stretch spring 11 are respectively pressed against the first anti-stretch mounting base 9 and the other end of the anti-stretch rope 10. In practice, when the waste separation net 5 is pulled up and flipped over, most of the waste can be pushed down. However, since the waste is wet, some may stick to the waste separation net 5. Therefore, it is necessary to quickly lift the waste separation net 5, and at the top, gently pull it upwards. The elasticity of the waste separation net 5 will bounce the stuck waste away, thus removing most of the waste. This is very practical. However, frequent pulling of the waste separation net 5 can easily cause irreversible damage to it, shortening its service life. Therefore, this preferred solution can solve the above problems. When the waste separation net 5 is pulled upward, the anti-stretch rope 10 also moves upward. At this time, the first anti-stretch spring 11 is compressed upward by the anti-stretch rope 10, and the force is transferred to the first anti-stretch spring 11, thereby providing a buffer for the waste separation net 5, preventing the waste separation net 5 from being damaged, and improving the service life of the waste separation net 5. It is very ingenious!

[0038] Furthermore, the first anti-stretch connection structure is located between the outer wall of the extraction tank 1 and the inner wall of the inner limiting cylinder 6, preventing waste residue from contacting the first anti-stretch connection structure, which can more thoroughly remove waste residue, while also protecting the first anti-stretch connection structure from being contaminated by wet waste residue.

[0039] Referring to Figures 3-5, the spiral feed guide plate 8 has less than 0.5 spiral turns; two spiral feed guide plates 8 are provided and symmetrically arranged between the inner limiting cylinder 6 and the outer limiting cylinder 7. This can shorten the time for waste residue to slide down and prevent the accumulation of waste residue.

[0040] Referring to Figures 1 and 2, the inward and outward tilting drive mechanism includes an inward and outward tilting connecting rod 12, an inward and outward tilting drive motor 13, and an inward and outward tilting transmission assembly. The inward and outward tilting transmission assembly includes an inward and outward tilting transmission plate 14, a gear and rack integrated structure 15, and a synchronous shaft. Two gear and rack integrated structures 15 are provided, and the synchronous shaft is poweredly connected between the two gear and rack integrated structures 15. The inward and outward tilting transmission plate 14 is fixedly installed between the two gear and rack integrated structures 15. The inward and outward tilting drive motor 13 is connected to one of the gear and rack integrated structures 15. The upper end of the inward and outward tilting connecting rod 12 is directly or indirectly connected to the inward and outward tilting transmission plate 14, and the lower end of the inward and outward tilting connecting rod 12 is fixedly connected to the bottom of the waste separation net 5. Through this structure, driven by the inward and outward tilting drive motor 13, the gear and rack integrated structure 15 moves vertically along with the inward and outward tilting transmission plate 14, thereby pulling the bottom of the waste separation net 5 up and down, achieving fully automated operation of tilting and lowering the waste separation net 5, saving manpower and resources.

[0041] Referring to Figures 5-8, the upper end of the inward / outward turning connecting rod 12 is connected to the inward / outward turning transmission plate 14 via a second anti-stretching connection structure. The second anti-stretching connection structure includes a second anti-stretching mounting base 17 and a second anti-stretching spring. The second anti-stretching mounting base 17 is fixedly disposed below the inward / outward turning transmission plate 14, and is provided with a bidirectional anti-stretching mounting slot. The upper end of the inward / outward turning connecting rod 12 can extend vertically into the bidirectional anti-stretching mounting slot, and the inward / outward turning connecting rod 12... The upper end is provided with a relatively large limiting part 1201; the second anti-stretch spring includes a second upper anti-stretch spring 19 and a second lower anti-stretch spring 20. The second upper anti-stretch spring 19 and the second lower anti-stretch spring 20 are both sleeved on the upper end of the inward and outward flip connecting rod 12. The upper and lower ends of the second upper anti-stretch spring 19 respectively abut against the upper bottom surface of the bidirectional anti-stretch mounting position and the limiting part 1201. The upper and lower ends of the second lower anti-stretch spring 20 respectively abut against the limiting part 1201 and the lower bottom surface of the bidirectional anti-stretch mounting position.

[0042] During the extraction process, the inward and outward turning drive mechanism repeatedly performs a stirring and agitation operation. This stirring and agitation operation is as follows: the inward and outward turning drive mechanism first pulls the waste residue separation net 5 upward, the height of which is set according to the actual situation, with the rule that the mango peel should not be exposed above the water surface; the inward and outward turning drive mechanism then pulls the waste residue separation net 5 downward, and the waste residue separation net 5 elastically stretches when it reaches the lowest position, ejecting the mango peel near the surface of the waste residue separation net 5 towards the center of the extraction tank 1, increasing the movement speed of the mango peel. In this way, the repeated up-and-down stirring and agitation of the mango peel during the extraction process can effectively accelerate the extraction speed and increase the polyphenol yield. Furthermore, since the upper end of the inward and outward flipping connecting rod 12 is held in place by the second upper anti-stretch spring 19 and the second lower anti-stretch spring 20, when the inward and outward flipping drive mechanism pulls the waste residue separation net bag 5 down to the lowest position, it will continue to pull the waste residue separation net bag 5 down a short distance, causing the waste residue separation net bag 5 to elastically stretch, thereby pushing the mango peel inward and increasing the movement amplitude and speed of the mango peel in the extraction tank 1; during this process, the second anti-stretch mounting seat 17 compresses the second upper anti-stretch spring 19 downward, and the second upper anti-stretch spring 19 adaptively transmits the power to the inward and outward flipping connecting rod 12, so that the inward and outward flipping connecting rod 12 gently pulls the waste residue separation net bag 5 down, which can both bounce the mango peel away and not damage the waste residue separation net bag 5, thus achieving a second layer of protection. In addition, when cleaning up waste residue, it is necessary to quickly lift the waste residue separation net bag 5. When it reaches the top, the waste residue separation net bag 5 will be pulled upward slightly. At this time, the second anti-stretch mounting seat 17 compresses the second lower anti-stretch spring 20 upward, and the second upper anti-stretch spring 19 deforms and transmits the power to the inner and outer flip connecting rods 12, thereby preventing the waste residue separation net bag 5 from being pulled hard. At the same time, it achieves double protection and further improves the service life of the waste residue separation net bag 5.

[0043] Furthermore, the ultrasonic lifting drive mechanism is composed of the inward and outward tilting drive mechanism, and the ultrasonic vibrator 4 is mounted on the inward and outward tilting transmission plate 14. This allows for simultaneous lifting and lowering along with the waste separation net 5, simplifying the structure and reducing costs.

[0044] Referring to Figures 1-3, the top of the outer limiting cylinder 7 is provided with two clearance holes 701 for avoiding the inward and outward turning transmission plates 14 and the synchronous shaft during lifting and lowering.

[0045] Furthermore, two sealing side plates 21 are provided below the inward and outward turning transmission plate 14, and the two sealing side plates 21 are respectively located outside the two clearance holes 701; the width of the sealing side plate 21 is greater than or equal to the width of the clearance hole 701, and the height of the sealing side plate 21 is greater than the height of the clearance hole 701. With the above structure, the inward and outward turning transmission plate 14 and the synchronous shaft are allowed to move vertically without interference, while the clearance holes 701 are sealed to prevent mango peel waste from flying out of the outer limiting cylinder 7.

[0046] Referring to Figures 1 and 2, the waste collection mechanism includes a waste collection box 22 and a guide component 23, which is located below the bottom of the spiral feed guide plate 8.

[0047] Referring to Figures 1-5, the working principle of the high-efficiency mango peel polyphenol extraction device in this embodiment is as follows:

[0048] During operation, the extractant is injected into extraction tank 1 through the inlet. The crushed mango peel is then poured into extraction tank 1, and the mango peel is held in place by the waste separation net 5 (the mesh size of the net is smaller than that of the crushed mango peel), as shown in Figure 4. The ultrasonic vibrator 4 is activated to ultrasonically vibrate the mango peel and the extractant, continuously separating and extracting the polyphenols from the mango peel, which remain in a free state in the extractant. After extraction, the outlet of extraction tank 1 is opened, and the polyphenol extract is temporarily stored in storage tank 3 before proceeding with subsequent operations. During this process, the waste separation net 5 can block the mango peel waste, preventing it from being discharged along with the polyphenol extract.

[0049] Next, the waste residue cleaning work is carried out. The ultrasonic vibrator 4 is driven to rise by the ultrasonic lifting drive mechanism, so that it is away from the waste residue separation net bag 5. The bottom of the waste residue separation net bag 5 is driven to move upward by the inward and outward flipping drive mechanism, so that the waste residue separation net bag 5 gradually begins to flip from bottom to top, pushing the waste residue upward until the waste residue separation net bag 5 is completely flipped up. At this time, the waste residue separation net bag 5 is in an inverted state. The waste residue falls from the waste residue separation net bag 5 onto the spiral feeding guide plate 8 between the inner limiting cylinder 6 and the outer limiting cylinder 7, and then slides down along the spiral feeding guide plate 8, as shown in Figure 5. Finally, it is collected by the waste residue collection mechanism.

[0050] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
