Description

Technical Field

[0001] This utility model relates to the field of astaxanthin technology, specifically to a raw material pretreatment device for astaxanthin extraction. Background Technology

[0002] Astaxanthin, also known as astaxanthin or astaxanthin flavonoid, was extracted in 1933 from aquatic products such as shrimp and crab as a purplish-red crystal. It was later identified as a carotenoid closely related to astaxanthin, hence the name astaxanthin. It is widely found in organisms such as shrimp, crab, fish, birds, certain algae, and fungi. As a non-provitamin A carotenoid, astaxanthin cannot be converted into vitamin A in animals, but it has the same antioxidant effect as carotenoids. Its ability to quench singlet oxygen and capture free radicals is more than 10 times higher than that of β-carotene and more than 100 times stronger than that of vitamin E. It is also known as "super vitamin E". The antioxidant properties, coloring properties, and immune-enhancing properties of astaxanthin have been widely recognized. Countries such as the United States have allowed its use as a food additive in production. As a natural food additive, it has broad development prospects.

[0003] When extracting astaxanthin from shrimp and crab, it is necessary to first remove impurities and dirt from the surface of the raw materials through a cleaning device, then crush them into smaller particles through a crushing device to increase the surface area for subsequent processing, and then use a cell wall breaking device to break down the cell walls of the raw materials to make astaxanthin easier to extract. These are just some of the pretreatment processes. The cleaning device, crushing device, and cell wall breaking device used in this pretreatment process can be referred to as a raw material pretreatment device for astaxanthin extraction.

[0004] However, when using ultrasonic cleaners or similar raw material pretreatment devices for astaxanthin extraction to clean shrimp and crabs, the cleaning efficiency is low, and live shrimp and crabs may crawl out of the cleaning device during the cleaning process; therefore, it does not meet the existing requirements. In response, we propose a raw material pretreatment device for astaxanthin extraction. Utility Model Content

[0005] The purpose of this utility model is to provide a raw material pretreatment device for astaxanthin extraction, so as to solve the problems mentioned in the background art, such as the low cleaning efficiency of ultrasonic cleaners used in astaxanthin extraction raw material pretreatment devices, and the possibility that live shrimp and crabs may crawl out of the cleaning device during the cleaning process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material pretreatment device for astaxanthin extraction, comprising an ultrasonic cleaning device body, wherein the ultrasonic cleaning device body contains a metal shrimp and crab storage basket, and a stepper motor is fixedly installed inside the outer shell of the ultrasonic cleaning device body below the metal shrimp and crab storage basket. The output shaft of the stepper motor is connected to a transmission shaft via a coupling. A square shaft is fixedly connected to the middle position of the upper end face of the transmission shaft. A metal rod fixed inside the metal shrimp and crab storage basket is provided on the outside of the square shaft. A square slot is provided at the middle position of the lower end face of the metal rod, and the square shaft is inserted into the square slot.

[0007] Preferably, the inner wall of the square slot has a square cross-sectional shape, the outer surface of the square rotating shaft fits against the inner wall of the square slot, and the square rotating shaft and the square slot are slidably connected.

[0008] Preferably, the outer side of the top end of the metal rod is provided with a sealing cover that covers the upper end face of the ultrasonic cleaning device body, and the lower end face of the sealing cover is in contact with the upper end face of the ultrasonic cleaning device body.

[0009] Preferably, a circular hollow metal disc is provided above the metal rod and is slidably installed at the middle position of the upper end face of the sealing cover, and a force-bearing rod is fixed inside the upper side of the circular hollow metal disc.

[0010] Preferably, a U-shaped push rod is fixed on both sides of the lower end face of the circular hollow metal disk. A rectangular fixing block is provided above the U-shaped push rod and is slidably connected to the sealing cover. From left to right, the front end face of the first rectangular fixing block and the rear end face of the second rectangular fixing block are fixed with a plug rod that slides into the sealing cover. A spring is sleeved on the outer surface of the plug rod, and the two ends of the spring are respectively connected to the rectangular fixing block and the sealing cover.

[0011] Preferably, an annular fixing groove is provided between the two rectangular fixing blocks on the outer surface of the top end of the metal rod, and the lower end surface of the rectangular fixing block is an inclined surface.

[0012] Preferably, a sealing cover plate is provided below the stepper motor on the lower end face of the ultrasonic cleaning device body, and the ultrasonic cleaning device body and the sealing cover plate are fixed together by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a stepper motor to drive the metal shrimp and crab storage basket used to hold the shrimp and crab to rotate during the cleaning process. By driving the metal shrimp and crab storage basket to rotate, the position and posture of the shrimp and crab will be continuously changed during the cleaning process, so that the ultrasonic waves can act more evenly on all parts of the shrimp and crab, including hard-to-reach corners and crevices. This helps to thoroughly remove dirt, impurities and microorganisms from the surface and crevices of the shrimp and crab. In addition, the rotational motion can increase the relative movement between the shrimp and the cleaning liquid, so that the cleaning liquid continuously impacts the surface of the shrimp and crab. This dynamic process can accelerate the removal of dirt. Through the above technical solution, the cleaning time of the equipment for shrimp and crab is shortened and its cleaning efficiency is improved.

[0015] 2. This utility model, when the sealing cover is placed on the upper surface of the ultrasonic cleaning equipment body, automatically fixes the sealing cover to the upper surface of the ultrasonic cleaning equipment body by means of the annular fixing groove and two rectangular fixing blocks fixed to the outer surface of the metal rod inside the metal shrimp and crab storage basket. By fixing the sealing cover with the above technical solution, it can prevent the shrimp and crabs inside the ultrasonic cleaning equipment body from crawling out on their own during the cleaning process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The ultrasonic cleaning device body 1 (model JG-28K15), stepper motor 4 (model DM542), and spring 16 (model JX110) mentioned in this utility model can be obtained from the market or through private customization.

[0023] like Figure 1 As shown, one embodiment of this utility model is provided: a raw material pretreatment device for astaxanthin extraction, including an ultrasonic cleaning device body 1, the ultrasonic cleaning device body 1 containing a metal shrimp and crab storage basket 3, a stepper motor 4 fixedly installed inside the shell of the ultrasonic cleaning device body 1 below the metal shrimp and crab storage basket 3, the output shaft of the stepper motor 4 being connected to a transmission shaft 5 via a coupling, a square shaft 6 being fixedly connected to the middle position of the upper end face of the transmission shaft 5, a metal rod 7 fixed inside the metal shrimp and crab storage basket 3 on the outside of the square shaft 6, a square slot 8 being provided at the middle position of the lower end face of the metal rod 7, and the square shaft 6 being inserted into the square slot 8.

[0024] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, the inner wall cross-section of the square slot 8 is square, and the outer surface of the square rotating shaft 6 is in contact with the inner wall of the square slot 8, and the square rotating shaft 6 and the square slot 8 are slidably connected; before using the equipment, align the square slot 8 on the lower end of the metal rod 7 fixed inside the metal shrimp and crab storage basket 3 with the square rotating shaft 6 connected to the stepper motor 4, and then place the metal shrimp and crab storage basket 3 inside the ultrasonic cleaning equipment body 1. After the metal shrimp and crab storage basket 3 is placed inside the ultrasonic cleaning equipment body 1, pour cleaning fluid into the ultrasonic cleaning equipment body 1, and then add shrimp and crabs into the metal shrimp and crab storage basket 3. After the metal shrimp and crab storage basket 3 is filled, cover it with the sealing cap 2, and then start the stepper motor 4. The stepper motor 4 can drive the square rotating shaft 6 connected to it through the transmission rotating shaft 5 to rotate. Due to the outer surface of the square rotating shaft 6 The surface of the metal rod 7 is in contact with the inner wall of the square slot 8 located at the lower end of the metal rod 7. When the square rotating shaft 6 rotates, the metal rod 7 and the metal shrimp and crab storage basket 3 fixed to the metal rod 7 will rotate together. By driving the metal shrimp and crab storage basket 3 to rotate during the cleaning process, the position and posture of the shrimp and crab will be continuously changed during the cleaning process, so that the ultrasonic waves can act more evenly on all parts of the shrimp and crab, including hard-to-reach corners and crevices. This helps to thoroughly remove dirt, impurities and microorganisms from the surface and crevices of the shrimp and crab. The rotational motion can also increase the relative movement between the shrimp and the cleaning liquid, so that the cleaning liquid continuously impacts the surface of the shrimp. This dynamic process can accelerate the removal of dirt. Through this embodiment, the cleaning time of the equipment for shrimp and crab is shortened and its cleaning efficiency is improved.

[0025] After the cleaning operation is completed, remove the sealing cover 2, and then simply grasp the metal rod 7 to remove the metal shrimp and crab storage basket 3 containing the shrimp and crab from the body 1 of the ultrasonic cleaning equipment. Then, install a new metal shrimp and crab storage basket 3 for the next cleaning operation. With the above technical solution, the metal shrimp and crab storage basket 3 used to store the shrimp and crab can be directly removed after the cleaning operation is completed. This prevents the situation where the shrimp and crab are fixed to the metal shrimp and crab storage basket 3 located inside the body 1 of the ultrasonic cleaning equipment by pliers, which would require a long time to remove the shrimp and crab one by one, thus affecting the cleaning effect of the equipment.

[0026] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 4 As shown, a sealing cover 2 is provided on the outer side of the top end of the metal rod 7, covering the upper end face of the ultrasonic cleaning device body 1, and the lower end face of the sealing cover 2 is in contact with the upper end face of the ultrasonic cleaning device body 1; a circular hollow metal disk 13 is provided above the metal rod 7, which is slidably installed in the middle of the upper end face of the sealing cover 2, and a force-bearing rod 14 is fixed on the upper side inside the circular hollow metal disk 13; a U-shaped push rod 12 is fixed on both sides of the lower end face of the circular hollow metal disk 13, and a rectangular fixing block 10 is provided above the U-shaped push rod 12, which is slidably connected to the sealing cover 2; from left to right, the front end face of the first rectangular fixing block 10 and the rear end face of the second rectangular fixing block 10 are both fixed with an insert rod 15 that slides into the sealing cover 2, and a spring 16 is sleeved on the outer surface of the insert rod 15, and the two ends of the spring 16 are respectively connected to the rectangular fixing block 10 and the sealing cover 2; an annular fixing groove 9 is provided between the two rectangular fixing blocks 10 located on the outer surface of the top end of the metal rod 7, and the rectangular fixing... The lower end face of the fixed block 10 is an inclined surface 11. When the sealing cover 2 is placed on the upper end face of the ultrasonic cleaning equipment body 1, the inclined surfaces 11 on the lower end faces of the two rectangular fixed blocks 10 inside the sealing cover 2 will contact the upper end face of the metal rod 7. Under the action of the inclined surfaces 11, as the sealing cover 2 descends, the rectangular fixed blocks 10 will be pushed outward and squeeze the spring 16 connected to them. After the sealing cover 2 is placed on the upper end face of the ultrasonic cleaning equipment body 1, the rectangular fixed blocks 10 can be pushed inward by the reaction force of the squeezed spring 16, so that the rear end of the first rectangular fixed block 10 and the front end of the second rectangular fixed block 10 from left to right are both inserted into the inclined surfaces 11 on the outer surface of the metal rod 7, thereby fixing the sealing cover 2. Through this embodiment, the sealing cover 2 placed on the upper end face of the ultrasonic cleaning equipment body 1 can be directly fixed, thereby preventing the shrimp and crabs inside the ultrasonic cleaning equipment body 1 from crawling out on their own.

[0027] After the cleaning of the shrimp and crab is completed, the circular hollow metal disc 13 is moved upward by the force rod 14. As the circular hollow metal disc 13 rises, the U-shaped push rod 12 fixed to the lower end face of the circular hollow metal disc 13 will also move upward. As the U-shaped push rod 12 rises, it will contact the inclined surface 11 located on the lower end face of the rectangular fixing block 10. Under the action of the inclined surface 11, the rectangular fixing block 10 will be gradually pushed outward as the U-shaped push rod 12 rises. When the rectangular fixing block 10 completely leaves the interior of the inclined surface 11 and is still applying an upward force to the force rod 14, the sealing cover 2 will be directly removed. With the above technical solution, no additional operation is required to fix or remove the sealing cover 2, thus ensuring the convenience of installing and removing the sealing cover 2.

[0028] As a preferred technical solution in this embodiment, such as Figure 4 As shown, a sealing cover plate is provided below the stepper motor 4 on the lower end face of the ultrasonic cleaning equipment body 1, and the ultrasonic cleaning equipment body 1 and the sealing cover plate are fixed together by screws; the sealing cover plate can seal and protect the stepper motor 4.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
