Abstract
Description
Technical Field
[0001] This invention relates to the field of Antarctic krill oil extraction technology, and in particular to an antioxidant Antarctic krill oil extraction device and method. Background Technology
[0002] Antarctic krill live in cold waters, and their oil is rich in omega-3 polyunsaturated fatty acids, primarily DHA and EPA. Antarctic krill oil is rich in omega-3 fatty acids, especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which have antioxidant properties. Current techniques often involve adding appropriate amounts of krill powder and extractants to an ultrasonic extraction device to extract the krill oil.
[0003] An existing ultrasonic extraction device for Antarctic krill oil (publication number: CN213172249U) has at least the following drawbacks: The above-mentioned patent uses a pre-crushing blade roller and a stirring column to mix and pre-crush the material in the tank. The pre-crushed material enters the crushing chamber for ultrasonic extraction and crushing. However, during ultrasonic extraction and crushing, the Antarctic krill fragments tend to stick together, resulting in incomplete ultrasonic extraction of Antarctic krill oil. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an antioxidant Antarctic krill oil extraction device and method.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An antioxidant Antarctic krill oil extraction device includes an extraction box, an ultrasonic generator fixedly installed on the bottom wall of the extraction box, a portal frame fixedly installed on the top of the extraction box, a crushing cylinder fixedly installed through the top of the portal frame, a support frame fixedly installed on the top of the portal frame, a feed hopper fixedly installed through the top of the support frame, through holes at both the top and bottom of the crushing cylinder, support plates fixedly installed on the inner walls of opposite sides of the extraction box, a material box installed on the inner wall of the extraction box, the top two sides of the material box slidingly installed with the upper surface of the support plate, and a plurality of water-permeable holes evenly distributed through the outer surface of the material box, and a crushing mechanism installed inside the crushing cylinder.
[0007] In this embodiment, the crushing mechanism includes a rotating rod that is rotatably installed between the top and bottom ends of the crushing cylinder. Multiple crushing blades are uniformly fixed on the outer surface of the rotating rod, and a swinging mechanism is provided between the rotating rod and the material box.
[0008] In this embodiment, the swing mechanism includes a cam fixedly installed at the bottom of the rotating rod, two fixed plates are installed at the top of the material box, the cam is disposed between the two fixed plates, and a stirring mechanism is installed inside the material box.
[0009] In this embodiment, the stirring mechanism includes multiple stirring rods that are rotatably installed through the bottom of the material box, and a rotating assembly is provided between the multiple stirring rods and the bottom wall of the extraction box.
[0010] In this embodiment, the rotating assembly includes a transmission gear fixedly installed at the bottom end of the stirring rod, and a rack is fixedly installed on the bottom wall of the extraction box, with the transmission gear meshing with the rack.
[0011] In this embodiment, an intermittent feeding mechanism is installed on the outer surface of the crushing cylinder. The intermittent feeding mechanism includes a drive shaft rotatably mounted on the outer surface of the crushing cylinder. An upper baffle is fixedly installed at the top of the drive shaft. The upper baffle is located between the crushing cylinder and the discharge end of the feed hopper. A lower baffle is fixedly installed at the bottom of the drive shaft. A fixing frame is fixedly installed at the bottom end of the crushing cylinder near its bottom through hole. A discharge pipe is fixedly installed through the fixing frame. The discharge pipe and the through hole are located on the same axis. The lower baffle is located between the bottom end of the crushing cylinder and the discharge pipe. A discharge hole is opened through the upper surface of both the upper and lower baffles. The positions of the two discharge holes are staggered.
[0012] In this embodiment, a drive gear is fixedly installed at the top of the rotating rod, and a toothed ring is fixedly installed on the outer periphery of the upper baffle. The drive gear meshes with the toothed ring.
[0013] In this embodiment, a C-shaped plate is fixedly installed at the top of the crushing cylinder, a drive motor is fixedly installed on the upper surface of the C-shaped plate, and the output end of the drive motor passes through the lower surface of the C-shaped plate and is fixedly installed at the rotation center of the rotating rod.
[0014] An antioxidant Antarctic krill oil extraction method includes the following steps:
[0015] S1: Place the Antarctic krill into the feed hopper, and use the intermittent feeding mechanism to intermittently feed the Antarctic krill into the crushing cylinder;
[0016] S2: The drive motor drives the rotating rod to rotate, which in turn drives the crushing blade to rotate, thus crushing the Antarctic krill in the crushing cylinder;
[0017] S3: The crushed Antarctic krill falls into the feed box through the discharge pipe, where the extraction solvent in the extraction box mixes with the crushed Antarctic krill. High-energy sound waves are generated by an ultrasonic generator, which breaks down the cell walls of the crushed Antarctic krill under physical and chemical action, releasing the desired components.
[0018] S4: After ultrasonic extraction is completed, the solution in the extraction chamber is collected, separated and filtered to obtain Antarctic krill oil.
[0019] The beneficial effects of this invention are as follows:
[0020] 1. Through the two feeding holes staggered on the upper and lower baffle plates, the whole Antarctic krill in the feed hopper can be intermittently fed into the crushing cylinder, and the crushed Antarctic krill in the crushing cylinder can be intermittently discharged into the feed box. This ensures that the Antarctic krill is uniformly processed during the ultrasonic extraction process, thereby improving the extraction efficiency.
[0021] 2. As the rotating rod rotates, it drives the cam installed at its bottom to rotate, causing the cam to continuously push the two fixed plates, which in turn causes the fixed plates to move the material box back and forth in the extraction box, so that the Antarctic krill fragments in the material box can be fully mixed with the extraction solvent, thereby improving the extraction effect of Antarctic krill oil.
[0022] 3. As the material box moves back and forth, it will drive the stirring rod installed at its bottom to move synchronously, causing the transmission gear installed at the bottom of the stirring rod to roll on the rack. This allows the transmission gear to drive the stirring rod to rotate, which in turn breaks up the Antarctic krill fragments in the material box, preventing the fragments from sticking together and further improving the extraction effect of Antarctic krill oil.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] See attached document Figure 1 -Appendix Figure 7 An antioxidant Antarctic krill oil extraction device includes an extraction box 1, an ultrasonic generator 22 fixedly installed on the bottom wall of the extraction box 1, a gantry frame 2 fixedly installed on the top of the extraction box 1, a crushing cylinder 3 fixedly installed through the top of the gantry frame 2, a support frame 4 fixedly installed on the top of the gantry frame 2, a feed hopper 5 fixedly installed through the top of the support frame 4, through holes at both the top and bottom of the crushing cylinder 3, support plates 16 fixedly installed on the inner walls of opposite sides of the extraction box 1, a material box 17 installed on the inner wall of the extraction box 1, the two sides of the top of the material box 17 slidingly installed with the upper surface of the support plate 16, and several water-permeable holes evenly opened through the outer surface of the material box 17, and a crushing mechanism installed inside the crushing cylinder 3.
[0034] In this embodiment, the crushing mechanism includes a rotating rod 10 that is rotatably installed between the top and bottom ends of the crushing cylinder 3. Multiple crushing blades 11 are uniformly fixed on the outer surface of the rotating rod 10, and a swinging mechanism is provided between the rotating rod 10 and the material box 17.
[0035] In this embodiment, the swing mechanism includes a cam 23 fixedly installed at the bottom of the rotating rod 10. Two fixing plates 20 are installed at the top of the feed box 17. The two fixing plates 20 are detachably installed at the top of the feed box 17 by bolts so that the two fixing plates 20 can be removed later, the feed box 17 can be taken out, and the Antarctic krill inside can be collected. The cam 23 is located between the two fixing plates 20. A stirring mechanism is installed inside the feed box 17. The stirring mechanism includes multiple stirring rods 18 that are rotatably installed through the bottom of the feed box 17. A rotating assembly is provided between the multiple stirring rods 18 and the bottom wall of the extraction box 1.
[0036] During use, the rotating rod 10 drives the cam 23 installed at its bottom to rotate, so that the cam 23 continuously pushes the two fixed plates 20, which in turn drives the material box 17 to move back and forth in the extraction box 1, so that the Antarctic krill fragments in the material box 17 can be fully mixed with the extraction solvent, thereby improving the extraction effect of Antarctic krill oil.
[0037] In this embodiment, the rotating assembly includes a transmission gear 19 fixedly installed at the bottom end of the stirring rod 18, and a rack 21 fixedly installed on the bottom wall of the extraction box 1, with the transmission gear 19 meshing with the rack 21.
[0038] When the feed box 17 moves back and forth, it will drive the stirring rod 18 installed at its bottom to move synchronously, so that the transmission gear 19 installed at the bottom of the stirring rod 18 rolls on the rack 21, thereby enabling the transmission gear 19 to drive the stirring rod 18 to rotate, so that the stirring rod 18 can break up the Antarctic krill fragments in the feed box 17, preventing the Antarctic krill fragments from sticking together, and further improving the extraction effect of Antarctic krill oil.
[0039] In this embodiment, an intermittent feeding mechanism is installed on the outer surface of the crushing cylinder 3. The intermittent feeding mechanism includes a drive shaft 6 rotatably mounted on the outer surface of the crushing cylinder 3. An upper baffle 7 is fixedly installed at the top of the drive shaft 6. The upper baffle 7 is located between the discharge end of the crushing cylinder 3 and the feed hopper 5. A lower baffle 8 is fixedly installed at the bottom of the drive shaft 6. A fixing frame 14 is fixedly installed at the bottom end of the crushing cylinder 3 near its bottom through hole. A discharge pipe 15 is fixedly installed through the fixing frame 14. The discharge pipe 15 and the through hole are located on the same axis. The lower baffle 8 is located on the crushing cylinder 3. Between the bottom end of the upper baffle 7 and the discharge pipe 15, the upper surfaces of both the upper baffle 7 and the lower baffle 8 are provided with discharge holes 9, which are staggered. The top of the rotating rod 10 is fixedly installed with a drive gear 12, and the outer periphery of the upper baffle 7 is fixedly installed with a gear ring 13. The drive gear 12 meshes with the gear ring 13. The top of the crushing cylinder 3 is fixedly installed with a C-shaped plate 24, and the upper surface of the C-shaped plate 24 is fixedly installed with a drive motor 25. The output end of the drive motor 25 passes through the lower surface of the C-shaped plate 24 and is fixedly installed with the rotation center of the rotating rod 10.
[0040] In use, the drive motor 25 drives the rotating rod 10 to rotate, which in turn drives the drive gear 12 to rotate. The drive gear 12 then drives the meshing gear ring 13 to rotate, which in turn drives the upper baffle 7 to rotate. This causes the feeding hole 9 on the upper baffle 7 to connect the feed hopper 5 and the crushing cylinder 3, allowing the Antarctic krill in the feed hopper 5 to fall into the crushing cylinder 3. Simultaneously, the upper baffle 7 rotates, which in turn drives the lower baffle 8 to rotate via the drive shaft 6. This causes the feeding hole 9 on the lower baffle 8 to be misaligned with the through hole at the bottom of the crushing cylinder 3, thus sealing the bottom of the crushing cylinder 3 and preventing incompletely crushed Antarctic krill from falling directly into the feed box 17, which would affect the subsequent extraction of Antarctic krill oil.
[0041] An antioxidant Antarctic krill oil extraction method includes the following steps:
[0042] S1: Place the Antarctic krill into the feed hopper 5, and use the intermittent feeding mechanism to intermittently feed the Antarctic krill into the crushing cylinder 3;
[0043] S2: The drive motor 25 drives the rotating rod 10 to rotate, which in turn drives the crushing blade 11 to rotate, thus crushing the Antarctic krill in the crushing cylinder 3.
[0044] S3: The crushed Antarctic krill falls into the feed box 17 through the discharge pipe 15, so that the extraction solvent in the extraction box 1 mixes with the Antarctic krill powder. The ultrasonic generator 22 generates high-energy sound waves, which cause the Antarctic krill powder to break the cell wall under physical and chemical action and release the required components.
[0045] S4: After ultrasonic extraction is completed, the solution in extraction chamber 1 is collected, separated and filtered to obtain Antarctic krill oil.
[0046] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: When in use, Antarctic krill is placed in the feed hopper 5, and the drive motor 25 drives the rotating rod 10 to rotate, which in turn drives the drive gear 12 to rotate, which in turn drives the gear ring 13 meshing with it to rotate, which in turn drives the upper baffle 7 to rotate, so that the discharge hole 9 on the upper baffle 7 connects the feed hopper 5 and the crushing cylinder 3, allowing the Antarctic krill in the feed hopper 5 to fall into the crushing cylinder 3. At the same time as the upper baffle 7 rotates, the lower baffle 8 is driven to rotate through the transmission shaft 6, so that the discharge hole 9 on the lower baffle 8 is offset from the through hole at the bottom of the crushing cylinder 3, so that the lower baffle 8 seals the bottom of the crushing cylinder 3, preventing the Antarctic krill that is not completely crushed from falling directly into the feed box 17, which would affect the subsequent extraction effect of Antarctic krill oil.
[0047] The two staggered discharge holes 9 on the upper baffle 7 and lower baffle 8 allow for the intermittent entry of whole Antarctic krill from the feed hopper 5 into the crushing cylinder 3 and the intermittent discharge of crushed Antarctic krill from the crushing cylinder 3 into the feed box 17. This ensures that the Antarctic krill is uniformly processed during ultrasonic extraction, thereby improving extraction efficiency.
[0048] When the rotating rod 10 rotates, it will drive the crushing blade 11 to rotate, so that the crushing blade 11 crushes the Antarctic krill in the crushing cylinder 3, so as to better extract the Antarctic krill oil in the future.
[0049] The crushed Antarctic krill falls into the feed box 17 through the discharge pipe 15, so that the extraction solvent in the extraction box 1 mixes with the Antarctic krill powder. The ultrasonic generator 22 generates high-energy sound waves, which break the cell walls of the Antarctic krill powder under physical and chemical action, releasing the desired components. After ultrasonic extraction is completed, the solution in the extraction box 1 is collected, separated and filtered to obtain Antarctic krill oil.
[0050] As the rotating rod 10 rotates, it drives the cam 23 installed at its bottom to rotate, so that the cam 23 continuously pushes the two fixed plates 20, so that the fixed plates 20 can drive the material box 17 to move back and forth in the extraction box 1, so that the Antarctic krill fragments in the material box 17 can be fully mixed with the extraction solvent, thereby improving the extraction effect of Antarctic krill oil.
[0051] When the feed box 17 moves back and forth, it will drive the stirring rod 18 installed at its bottom to move synchronously, so that the transmission gear 19 installed at the bottom of the stirring rod 18 rolls on the rack 21, thereby enabling the transmission gear 19 to drive the stirring rod 18 to rotate, so that the stirring rod 18 can break up the Antarctic krill fragments in the feed box 17, preventing the Antarctic krill fragments from sticking together, and further improving the extraction effect of Antarctic krill oil.
[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
