[0002] Astaxanthin is a ketocarotenoid, a red solid powder that is fat-soluble, insoluble in water, and soluble in organic solvents. It is widely present in the biological world, particularly in the feathers of aquatic animals such as shrimp, crab, fish, and birds, where it contributes to color development. Astaxanthin has strong antioxidant properties, scavenging free radicals in the body and reducing the damage caused by oxidative stress. It is widely used in health supplements, cosmetics, and food. It may also play a role in preventing and improving some chronic diseases and protecting eye and skin health.

[0032] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a production equipment for producing high-astaxanthin dried shrimp includes a base 1, and the base 1 is provided with an intermediate bracket 10 and an upper bracket 11 from bottom to top. The upper bracket 11 is fixedly connected to the intermediate bracket 10, and an extraction cylinder 2 is installed at the bottom of the upper bracket 11. An extractant cylinder 3 is provided on the upper bracket 11, and the extractant cylinder 3 is connected to an injection pipe 60, and the injection pipe 60 is connected to a pumping mechanism 6. A feed port is provided on the extraction cylinder 2, and the feed port is located directly below the pumping mechanism 6. A slide plate 20 is slidably installed at the feed port. A sliding column 22 is provided at the feed port of the extraction cylinder 2, and the slide plate 20 is slidably installed between the sliding column 22. A sleeve spring 23 is provided on the sliding column 22. Clamps are sleeved at both ends of the extraction cylinder 2, and the extraction cylinder 2 is suspended from the bottom of the upper bracket 11 through the clamp. Installation, one end of the extraction cylinder 2 is provided with an outer gear ring 25, and a driving motor 28 is suspended at the bottom of the upper bracket 11. The driving motor 28 is connected to a driving gear 27, and the driving gear 27 is meshed with the outer gear ring 25. The front end of the upper bracket 11 is provided with a front side plate 12, and the inner side of the front side plate 12 is provided with a feeding trough 13. After the extraction cylinder 2 rotates, it cooperates with the feeding trough 13. An opening and closing mechanism 7 is provided on the front side plate 12. The opening and closing mechanism 7 is used to control the opening and closing of the slide plate 20 and the feed port. A crushing assembly is provided in the extraction cylinder 2, and the pumping mechanism 6 and the slide plate 20 are detachable and docked. A drying mechanism 5 is provided at the bottom of the intermediate bracket 10, and the drying mechanism 5 is connected to the same pumping mechanism 6, and the drying mechanism 5 is docked with the slide plate 20 through the pumping mechanism 6.

[0034] Specifically, the extraction cylinder 2 is suspended and mounted on the upper bracket 11, and a slide 20 is provided on the extraction cylinder 2. The slide 20 is controlled by the opening and closing mechanism 7 to move along the slide column 22, thereby controlling the opening or closing of the feed port. A front side plate 12 is provided on the upper bracket 11, and a feeding trough 13 is mounted on the front side plate 12. When the feed port on the extraction cylinder 2 rotates to the feeding trough 13, the opening and closing mechanism 7 controls the slide 20 to open, thereby feeding shrimp shells into the extraction cylinder 2. The extractant cylinder 3, the injection pipe 60, and the pumping mechanism 6 are combined to inject the extractant into the extraction cylinder 2. The shrimp shells are crushed by the crushing assembly to increase the extraction rate of the extractant on astaxanthin. After the astaxanthin is extracted, the extraction cylinder 2 is rotated so that the slide 20 is aligned with the pumping mechanism 6 on the drying mechanism 5. The extractant containing astaxanthin is extracted into the drying mechanism 5 and dried together with the shrimp meat, thereby increasing the astaxanthin content in the dried shrimp.

[0035] Among them, the extraction agent is selected as 75% ethanol solution. While extracting astaxanthin, the ethanol can be completely separated from the shrimp meat when participating in the drying of the shrimp meat in the subsequent drying mechanism 5, leaving only the astaxanthin component, avoiding the introduction of other impurities.

[0036] Further, such as Figure 4 、 Figure 5As shown, the crushing assembly includes a docking plate 260 arranged at the edge of the extraction cylinder 2, the docking plate 260 and the extraction cylinder 2 are sealed and docked, a crushing motor 26 is provided at the center of the docking plate 260, and crushing blades 261 are evenly provided on the output shaft of the crushing motor 26. A telescopic cylinder 29 is fixedly provided on the top of the upper bracket 11, and the output end of the telescopic cylinder 29 is connected to the connecting frame 210, and the connecting frame 210 is fixedly connected to the outer side of the docking plate 260.

[0037] Specifically, after the shrimp shells are put into the extraction cylinder 2, the crushing motor 26 on the docking plate 260 drives the crushing blade 261 to rotate in the extraction cylinder 2 to crush the shrimp shells. After the crushing is completed, the extractant is injected into the extraction cylinder 2 through the injection pipe 60 and the pumping mechanism 6, and the crushing component is continued to start to stir the extractant, thereby improving the extraction effect.

[0038] Further, such as Figure 6 As shown, the opening and closing mechanism 7 includes a lifting motor 70 arranged on the front side plate 12, the lifting motor 70 is connected to the mounting frame 71, the mounting frame 71 is connected to abutment block 72, the abutment block 72 is provided with a plug-in column 74, the abutment block 72 is plugged into the mounting frame 71 through the plug-in column 74, the plug-in column 74 is sleeved with a tensioning spring 75, the inner side of the abutment block 72 and the outer wall of the extraction cylinder 2 cooperate with each other, a push-pull cylinder 77 and a horizontal column 76 are fixedly provided on the mounting frame 71, a connecting plate 78 is provided at the end of the horizontal column 76, the output end of the push-pull cylinder 77 is connected to the connecting plate 78, the other end of the horizontal column 76 is provided with a docking hook 79, and a docking hole 200 is provided on the slide plate 20, and the docking hook 79 and the docking hole 200 cooperate with each other.

[0039] Specifically, when the extraction cylinder 2 rotates to the feeding trough 13, the lifting motor 70 controls the mounting frame 71 and the abutment block 72 to approach the outer wall of the extraction cylinder 2, so that the docking hook 79 cooperates with the docking hole 200 on the slide 20, and the push-pull cylinder 77 drives the horizontal column 76 and the docking hook 79 to make the slide 20 slide along the sliding column 22, thereby opening the feeding port and realizing the feeding of shrimp shells.

[0040] Further, such as Figure 3 、 Figure 6 As shown, a matching block 73 is provided on the abutting block 72 , and a positioning groove 24 that cooperates with the matching block 73 is provided on the extraction cylinder 2 .

[0041] Specifically, the rotation angle of the extraction cylinder 2 is determined by setting the matching block 73 and the positioning groove 24. When the extraction cylinder 2 is rotating, if the matching block 73 on the abutment block 72 falls into the positioning groove 24, the rotation of the extraction cylinder 2 is stopped. At this time, the feeding trough 13 and the feeding port on the extraction cylinder 2 are matched with each other to avoid spillage during feeding.

[0042] Further, such as Figure 7 As shown, a material injection hole 21 is provided on the slide plate 20, and two groups of sealing disks 201 are provided in the material injection hole 21. Leakage holes are evenly provided on the sealing disks 201. A filter screen is provided on the inner sealing disk 201. A group of sealing disks 201 facing the outside of the extraction cylinder 2 is rotatably installed between the material injection hole 21. A clamping column 202 is provided at the center of the sealing disk 201, and the clamping column 202 is slidably docked with the center of the docking joint 66.

[0043] Specifically, to facilitate the injection and extraction of the extractant, two sets of sealing disks 201 are positioned at the injection port 21. When the leak holes on the outer sealing disk 201 are staggered with the leak holes on the inner sealing disk 201, leaks of the extractant are prevented, achieving a sealing effect. When the extraction mechanism 6 docks with the clamping post 202, it drives the outer sealing disk 201 to rotate, connecting the leak holes on the inner and outer sealing disks 201. At this point, in conjunction with the extraction mechanism 6, extraction of the extractant is possible.

[0044] Further, such as Figure 7 、 Figure 8 As shown, the pumping mechanism 6 includes a mounting plate 61, on which an electric telescopic column 63 is provided. The electric telescopic column 63 is connected to a limiting frame 62, and a locking ball 620 is provided on the inner side of the limiting frame 62. The limiting frame 62 is slidably engaged with the outer gear ring 2 67 through the locking ball 620. The outer gear ring 2 67 is connected with a docking joint 66, and a telescopic tube 69 is provided between the docking joint 66 and the mounting plate 1 61. A rotary motor 64 is provided at the edge of the mounting plate 1 61, and an electric telescopic column 2 65 is connected to the output shaft of the rotary motor 64. A driving gear 2 68 is provided at the end of the electric telescopic column 2 65, and the driving gear 2 68 and the outer gear ring 2 67 are meshed with each other.

[0045] Specifically, when the docking joint 66 and the clamping column 202 are docked with each other, the rotary motor 64 and the driving gear 2 68 are combined to control the outer ring gear 2 67 to rotate. At this time, the docking joint 66 rotates along with the outer ring gear 2 67, driving the clamping column 202 on the sealing disk 201 to rotate together, thereby controlling the rotation of the sealing disk 201. When the leakage holes between the two groups of sealing disks 201 penetrate each other, the extraction pump in the docking joint 66 is combined to realize the extraction of the extraction liquid.

[0046] More specifically, the docking joint 66 and the clamping column 202 are controlled to dock or separate with each other by the electric telescopic column 1 63 and the electric telescopic column 2 65 , while ensuring the rotation control of the blocking disk 201, thereby controlling the extraction of the extractant.

[0047] Further, such as Figure 9 、 Figure 10 、 Figure 11As shown, a pitch adjustment mechanism 4 is provided between the intermediate bracket 10 and the base 1, and the pitch adjustment mechanism 4 includes a support column 40 rotatably installed on one side of the intermediate bracket 10, and a connecting rod 41 rotatably installed on the other side of the intermediate bracket 10. An adjustment slide rail 42 is provided on the base 1, and a bending frame 43 is slidably installed between the adjustment slide rails 42. The connecting rod 41 and the bending frame 43 are rotatably installed, and a matching gear 44 is rotatably installed in the bending frame 43. The matching gear 44 is connected to a travel motor 45, and a matching rack 46 is provided between the adjustment slide rails 42. The matching gear 44 and the matching rack 46 are engaged with each other.

[0048] Specifically, by setting a travel motor 45 and a connecting rod 41 to control the back-and-forth pitching movement of the intermediate bracket 10, the shrimp shells in the extraction cylinder 2 are driven to move back and forth, thereby further improving the crushing effect of the shrimp shells. At the same time, the back-and-forth pitching can improve the extraction effect of the extractant on astaxanthin in the shrimp shells.

[0049] Further, such as Figure 12 As shown, the drying mechanism 5 includes a drying box 50, a drying fan 51 is provided at the bottom of the drying box 50, heat exhaust holes 52 are evenly provided on the top of the drying box 50, and the suction mechanism 6 on the top of the drying box 50 is connected to a hanging pipe 53, which is horizontally arranged on the inner side of the drying box 50, and a plug-in rod 54 is evenly installed on the lower side of the hanging pipe 53, and the plug-in rod 54 and the hanging pipe 53 are connected, and overflow holes 540 are evenly provided on the outside of the plug-in rod 54.

[0050] Specifically, the shrimp meat is inserted into the connecting rod 54, and the extractant containing astaxanthin is continuously injected into the shrimp meat through the hanging tube 53 and the overflow hole 540 on the connecting rod 54, while the drying fan 51 continuously dries the shrimp meat. During the repeated drying and injection of the extractant, the astaxanthin content in the dried shrimp is increased.

[0051] A production method for producing high-astaxanthin dried shrimp production equipment as described above includes the following steps: S1, controlling the extraction cylinder 2 to rotate to the feeding trough 13 by driving the motor 28, controlling the slide 20 on the extraction cylinder 2 to move in conjunction with the opening and closing mechanism 7, opening the feeding port, feeding shrimp shells into the feeding port through the feeding trough 13, and then controlling the extraction cylinder 2 to return to the initial position; S2, crushing the shrimp shells by the crushing assembly, and injecting the extractant into the extraction cylinder 2 through the injection hole 21 on the slide 20 in conjunction with the extractant cylinder 3 and the pumping mechanism 6; S3, After the extractant extracts and separates the astaxanthin in the shrimp shell, the extraction cylinder 2 is controlled to rotate by the driving motor 28 so that the clamping column 202 on the extraction cylinder 2 is aligned with the extraction mechanism 6 on the drying mechanism 5. The extraction agent containing astaxanthin in the extraction cylinder 2 is drawn into the hanging tube 53 through the extraction mechanism 6 on the drying mechanism 5, and the shrimp meat is inserted into the plug-in rod 54. The extraction agent containing astaxanthin is continuously injected into the shrimp meat in combination with the overflow hole 540 on the plug-in rod 54, and the drying fan 51 is used for continuous air drying to enrich the astaxanthin in the dried shrimp and increase the astaxanthin content in the dried shrimp.

[0052] The working principle of the embodiment of the present invention is:

[0053] like Figures 1-12As shown, an extraction cylinder 2 is suspended and mounted on an upper bracket 11. A slide 20 is provided on the extraction cylinder 2. The slide 20 is controlled by an opening and closing mechanism 7 to move along a slide post 22, thereby controlling the opening or closing of the feed port. A front side plate 12 is provided on the upper bracket 11, and a feeding trough 13 is mounted on the front side plate 12. When the feed port on the extraction cylinder 2 rotates to the feeding trough 13, the opening and closing mechanism 7 controls the slide 20 to open, allowing shrimp shells to be fed into the extraction cylinder 2. The extractant cylinder 3, the injection pipe 60, and the pumping mechanism 6 are combined to inject the extractant into the extraction cylinder 2. The shrimp shells are then crushed by the crushing assembly to increase the extraction efficiency of the extractant on astaxanthin. After the astaxanthin is extracted, the extraction cylinder 2 is rotated so that the slide 20 is aligned with the pumping mechanism 6 on the drying mechanism 5. The extractant containing astaxanthin is drawn into the drying mechanism 5 and dried together with the shrimp meat, thereby increasing the astaxanthin content in the dried shrimp. After the shrimp shells are put into the extraction cylinder 2, the crushing motor 26 on the docking plate 260 drives the crushing blade 261 to rotate in the extraction cylinder 2 to crush the shrimp shells. After the crushing is completed, the extractant is injected into the extraction cylinder 2 through the injection pipe 60 and the pumping mechanism 6, and the crushing component is continued to start to stir the extractant, thereby improving the extraction effect. When the extraction cylinder 2 rotates to the feeding trough 13, the lifting motor 70 controls the mounting frame 71 and the abutment block 72 to approach the outer wall of the extraction cylinder 2, so that the docking hook 79 and the docking hole 200 on the slide 20 cooperate with each other. The push-pull cylinder 77 drives the horizontal column 76 and the docking hook 79 to make the slide 20 slide along the sliding column 22, thereby opening the feed port and realizing the feeding of shrimp shells. By arranging two sets of blocking disks 201 at the feeding hole 21, when the leakage hole on the outer blocking disk 201 and the leakage hole on the inner blocking disk 201 are staggered, the extraction agent will be prevented from leaking, achieving a sealing effect. When the pumping mechanism 6 docks with the clamping post 202, it drives the outer sealing disk 201 to rotate, connecting the leak holes on the inner and outer sealing disks 201. This allows the extraction of the extractant by the pumping mechanism 6. The shrimp meat is inserted into the plug rod 54, and the extractant containing astaxanthin is continuously injected into the shrimp meat through the hanging tube 53 and the overflow hole 540 on the plug rod 54. The drying fan 51 continuously dries the shrimp meat. This repeated drying and extractant injection process increases the astaxanthin content in the dried shrimp.
