Description

Technical Field

[0001] This invention belongs to the technical field of refrigeration equipment, and relates to a refrigeration device for fish swim bladder oligopeptides, particularly a refrigeration device and method for facilitating the use of fish swim bladder oligopeptides. Background Technology

[0002] Fish swim bladder oligopeptides are small molecule peptides extracted from fish swim bladders using enzymatic hydrolysis technology. They have advantages such as high nutritional value and easy absorption. However, as highly active protein fragments, the stability of fish swim bladder oligopeptides is greatly affected by temperature, humidity, oxygen, and light. They need to be stored in a low-temperature environment, usually 0-4℃, dry and protected from light, to maintain their biological activity and prevent deterioration. Currently, they are usually stored in ordinary refrigerators or freezers.

[0003] A search revealed a Chinese patent document that discloses an easily accessible refrigeration device for biotechnology [Application No.: CN201810787399.0; Publication No.: CN108849849A]. This refrigeration device includes a base, with second telescopic rods bolted to the four corners of the base's bottom. A first telescopic rod is inserted into the bottom of the second telescopic rod. A first through hole is formed on the top of the outer wall of the first telescopic rod, and a fastening bolt is threaded into the first through hole.

[0004] The refrigeration device disclosed in this patent uses indicator lights to locate items. However, when retrieving items, the frequent opening of the refrigeration device causes drastic temperature changes, resulting in "temperature shocks," which accelerates the deterioration of the quality of fish swim bladder oligopeptides. Moreover, the large fluctuations in ambient humidity caused by opening the door to retrieve items lead to a decrease in their biological activity. Furthermore, when fish swim bladder oligopeptides are left to stand for a long time in a low-temperature environment, the material at the bottom is easily affected by pressure and ambient humidity penetration, forming a solid clump that makes it impossible to retrieve the items smoothly. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a refrigeration device and method for facilitating the use of fish swim bladder oligopeptides. The technical problem to be solved by this invention is: how to achieve sealed refrigeration and precise quantitative use of fish swim bladder oligopeptides using refrigeration equipment.

[0006] The objective of this invention can be achieved through the following technical solutions: A refrigeration device for facilitating the handling of fish swim bladder oligopeptides includes a body, a support foot fixedly connected to the bottom of the body, and an observation window fitted onto the surface of the body. A storage tank is fixedly installed inside the body, and a guide cylinder is fixedly connected to the bottom of the storage tank. A fixed cylinder is fixedly installed at the bottom of the guide cylinder. A rotating cylinder is rotatably connected inside the fixed cylinder, and multiple metering grooves are equidistantly arranged in a ring inside the rotating cylinder. A gear ring is sleeved on the outer wall of the rotating cylinder and rotatably connected to the inside of the fixed cylinder. A gear disk is meshed on the outer wall of the gear ring and rotatably connected to the outside of the fixed cylinder. A through groove is provided on the outer wall of the fixed cylinder to accommodate the meshing of the gear disk and the gear ring. The gear disk is externally connected to a material loosening unit, which is located inside the storage tank. A piston cylinder is fixedly connected to the top of the fixed cylinder, and a piston head is attached to the inner wall of the piston cylinder. A piston rod is fixedly connected to the top of the piston head, and a pressure plate is fixedly installed on the top of the piston rod. The pressure plate is disposed through one side of the machine body, and a support spring is fixedly connected to the bottom of the pressure plate. The bottom of the support spring is fixedly connected to the machine body. The top of the storage tank has a feed inlet, and a feeding unit is provided above the feed inlet. The bottom of the machine body has a discharge outlet, which is located below the piston cylinder.

[0007] The working principle of this invention is as follows: During refrigeration, the machine is powered on, the refrigeration system is started, and the target temperature of the inner storage tank is set to 4±1℃ via a button. After 2-4 hours, the internal temperature of the inner storage tank stabilizes within the set range. Once the internal temperature of the inner storage tank is stable, the feed cylinder is pressed downwards, compressing the return spring. This causes the feed cylinder to press against two baffles at the bottom wedge-shaped part, which in turn press against the torsion spring. This opens the inner storage tank from above, allowing the user to slowly and evenly pour the fish bladder oligopeptide powder into the inner storage tank through the feed cylinder, and observe the process through the observation window. Material quantity observation ensures accurate feeding. After feeding, to ensure the sealing effect of fish bladder oligopeptide powder inside the storage tank, the drive motor rotates the upright, causing the gear disc to drive the rotating cylinder to rotate inside the fixed cylinder via the gear ring. This rotating cylinder causes the sealing groove to seal at the bottom of the guide cylinder. Furthermore, through the transmission connection between the gear disc and the rotating rod, when the gear disc rotates, the rotating rod simultaneously drives the loosening rake to rotate inside the storage tank to rake the material, preventing material accumulation. Simultaneously, when the upper feeding cylinder is not under pressure, it does not press against the baffle, allowing the baffle to seal the top of the storage tank, thus ensuring the fish bladder oligopeptide... The powder is effectively sealed inside the storage tank, and the temperature is monitored in real time by the machine to ensure the refrigerated quality of the fish bladder oligopeptide powder. During daily retrieval of the fish bladder oligopeptide powder, the drive motor rotates the upright, causing the gear disc to drive the rotating drum inside the fixed cylinder via the gear ring. This rotating drum causes the corresponding metering slot to rotate below the guide cylinder. Simultaneously, under the transmission action of the upright and rotating rod, the rotating drum, while rotating, drives the loosening rake to pre-loosen the powder inside the storage tank, ensuring that the fish bladder oligopeptide powder enters efficiently and accurately when the metering slot rotates to the bottom of the guide cylinder. The metering trough, once full, is rotated again by the gear disc, causing the rotating cylinder to rotate the full trough to below the piston cylinder. A pressure plate is then pressed down, causing the piston head to move downwards via the piston rod. This allows the fish bladder oligopeptide powder inside the trough to be efficiently discharged downwards through the outlet under the air pressure of the piston head. After the metered amount of fish bladder oligopeptide powder is used, the drive motor drives the gear disc again, causing the gear ring to rotate, which in turn rotates the rotating cylinder. This rotates the sealed trough back to below the guide cylinder, achieving a resealing of the inner storage container after material removal and ensuring the refrigeration quality inside the inner storage container.

[0008] The loosening unit includes a rotating rod, which is rotatably connected to the inside of the storage tank. Multiple loosening rakes are fixedly connected to the outer wall of the rotating rod, and multiple lifting chains are fixedly connected to the bottom end of the rotating rod. Each lifting chain has a clearing ring fixedly installed at its bottom end, and the clearing ring is located inside the guide cylinder. The end of the loosening rake furthest from the rotating rod is inclined downwards, and the outer end of the loosening rake is multi-toothed. The bottom of the inner storage tank is designed in a bucket shape.

[0009] With the above structure, the inclined loosening rake allows the rotating rod to drive the loosening rake to rotate inside the storage tank to rake the material, avoiding material accumulation and loosening the material before discharge. This effectively breaks up nascent agglomerates, prevents caking and bridging, and ensures the flowability of the material.

[0010] The feeding unit includes two baffles, which are rotatably connected inside the feed inlet and are symmetrically arranged. Torsion springs are fixedly installed at the bottom ends of the two baffles.

[0011] By adopting the above structure and setting baffles and torsion springs, the baffles automatically close the feed inlet under the elastic action of the torsion springs, ensuring the sealing effect of the upper part of the storage tank. Moreover, by setting the torsion springs, when the baffles are squeezed from above, the two baffles can squeeze the torsion springs, thereby opening the feed inlet and facilitating the addition of materials into the storage tank. Compared with the existing method of opening and closing the door to retrieve and add materials, this method reduces the interference with the internal temperature and humidity of the storage tank, while avoiding the loss of cold energy and ensuring the refrigerated quality of fish swim bladder oligopeptides.

[0012] A feed cylinder is provided above the baffle, and the feed cylinder is telescopically extended and passed through the top of the machine body. A return spring is fixedly connected to the bottom wall of the top of the feed cylinder, and the bottom end of the return spring is fixedly installed on the top of the machine body. Multiple return springs are arranged circumferentially and equidistantly on the outer wall of the feed cylinder. The bottom of the feed cylinder has two symmetrically arranged wedge-shaped parts, and the two wedge-shaped parts are correspondingly arranged above the two baffles.

[0013] With the above structure, the corresponding arrangement of the wedge and the baffle ensures that the baffle only opens the inner storage tank when the feed cylinder is pressed downwards, thus guaranteeing the sealing effect inside the inner storage tank, effectively isolating it from outside air and moisture, and providing excellent preservation.

[0014] A vertical rod is fixedly installed inside the gear disk. The vertical rod is rotatably connected to the outside of the fixed cylinder and is driven by a drive motor. The top outer wall of the upright is fixedly connected to a first synchronous pulley, and the outer wall of the first synchronous pulley is fitted with a synchronous belt. The inner wall of the synchronous belt is also fitted with a second synchronous pulley, and the second synchronous pulley is fixedly installed on the outer wall of the rotating rod, and the second synchronous pulley is located at the top of the storage tank.

[0015] By adopting the above structure, by setting the first synchronous pulley at the top of the upright, the rotating rod can simultaneously drive the loosening rake to rotate inside the storage tank under the action of the synchronous belt, thereby avoiding material accumulation and ensuring that the fish swim bladder oligopeptides are loosened inside the storage tank, effectively preventing material accumulation and caking.

[0016] The top of the upright is rotatably connected to the inner top wall of the machine body, and the bottom end of the upright is fixedly installed with the output end of the drive motor, which is fixedly installed on the outer wall of the fixed cylinder.

[0017] With the above structure and the setting of the drive motor, the upright can drive the gear disk to rotate stably. Under the meshing action of the gear disk and the gear ring, the drive motor can drive the gear ring to rotate stably, ensuring the driving effect of the rotating cylinder. It also makes reasonable use of the internal space of the machine body, with a compact structure and strong practicality.

[0018] The top of the fixed cylinder is provided with a guide hole, and the guide hole is correspondingly provided below the guide cylinder; The top of the rotating cylinder is fitted with a closed groove that is larger than the feed guide hole, and the closed groove and the metering groove are arranged in a ring at equal intervals.

[0019] By adopting the above structure and setting the sealing groove, the sealing groove below the material guide cylinder can seal the bottom of the storage tank, effectively isolating it from outside air and moisture, minimizing the loss of cold air, maintaining stable internal temperature, and greatly improving the energy-saving effect of the refrigeration equipment.

[0020] The surface of the fixed cylinder is also provided with a push hole, and a piston cylinder is fixedly installed at the top of the push hole, and the push hole is located above the discharge port.

[0021] With the above structure, under the action of the push hole, when the piston head moves inside the piston cylinder, the fish bladder oligopeptide powder inside the metering tank is pushed downward at high speed by the piston head. This effectively prevents the fish bladder oligopeptide powder from "bridging" or sticking to the wall inside the metering tank. After the material is taken out, the connection between the pressure plate and the support spring allows the piston head to evacuate the inside of the metering tank when it moves upward, avoiding any residue inside the metering tank and ensuring that the metering tank is completely emptied, thereby ensuring the accuracy of each measurement.

[0022] A refrigeration method for a refrigeration device that facilitates the access of fish swim bladder oligopeptides, characterized by the following steps when applied to the aforementioned refrigeration device: S1. Equipment pre-cooling: Connect the power supply to the machine body, start the refrigeration system, and set the target temperature of the inner storage tank to 4±1℃ by pressing the button. After 2-4 hours, the internal temperature of the inner storage tank will stabilize within the set range. S2, Filling the hopper: Pressing the feed cylinder downwards causes it to press two baffles through the wedge-shaped part at the bottom, opening the storage tank from above. This allows the user to slowly and evenly pour the fish bladder oligopeptide powder into the storage tank through the feed cylinder and observe the amount of material through the observation window. S3. Sealed Refrigeration: Driven by the drive motor, the gear disk drives the rotating cylinder to rotate inside the fixed cylinder through the gear ring. The rotating cylinder drives the sealing groove to seal at the bottom of the guide cylinder. At the same time, the upper feed cylinder does not squeeze the baffle when it is not under force, so that the baffle seals the top of the storage inner barrel. This effectively seals the fish swim bladder oligopeptide powder inside the storage inner barrel. The temperature is monitored in real time by setting the machine body. S4. Daily Use: The rotating drum drives the corresponding metering trough to rotate below the guide cylinder. At the same time, under the transmission action of the upright rod and the rotating rod, the rotating drum drives the loosening rake to loosen the material in advance inside the storage barrel. This ensures that when the metering trough rotates to the bottom of the guide cylinder, the fish bladder oligopeptide powder enters the metering trough efficiently and accurately. After the metering trough is full, the gear disc rotates again, causing the rotating drum to drive the full metering trough to rotate below the piston cylinder. By pressing down the pressure plate, the pressure plate drives the piston head to move downward through the piston rod, so that the fish bladder oligopeptide powder inside the metering trough is efficiently discharged through the outlet under the air pressure of the piston head. S5. Reseal after use: After the fish bladder oligopeptide powder is discharged, the rotating drum rotates the sealing trough to the bottom of the guide cylinder, thus resealing the inner storage tank after the material is taken out, ensuring the refrigeration quality inside the inner storage tank.

[0023] Compared with the prior art, the refrigeration equipment and refrigeration method for facilitating the use of fish swim bladder oligopeptides of the present invention have the following advantages: 1. In this invention, by setting a baffle on the top of the inner storage tank and setting a sealing groove inside the rotating cylinder to seal the bottom of the inner storage tank, the external air and moisture of the inner storage tank during refrigeration are effectively isolated, resulting in excellent preservation effect. Moreover, the fish swim bladder oligopeptides are taken from the bottom of the inner storage tank by the rotating cylinder driving the metering groove. The entire taking process does not require large-scale opening of the inner storage tank, minimizing the loss of cold air, maintaining stable internal temperature, and achieving good energy-saving effect.

[0024] 2. In this invention, by equidistantly arranging multiple metering grooves in an annular pattern inside the rotating cylinder, the rotating cylinder can switch the function of the bottom of the guide cylinder through rotation under the action of the metering grooves and the sealing grooves. Moreover, by fixing the volume of the metering grooves, the height of each dispensing is kept consistent. Furthermore, the rotation sequence of the rotating cylinder completes the rotation, metering, pushing and sealing, making the operation simple and achieving stable, low-interference dispensing.

[0025] 3. In this invention, under the action of the piston cylinder, the user can push the fish bladder oligopeptide powder inside the corresponding metering tank downward at high speed under the action of the piston head, effectively preventing the fish bladder oligopeptide powder from "bridging" or sticking to the wall inside the metering tank. After the material is taken out, through the connection between the pressure plate and the support spring, the piston head can be emptied upward when it moves upward, avoiding residue inside the metering tank and ensuring that the metering tank is completely emptied, thereby ensuring the accuracy of each measurement.

[0026] 4. In this invention, by connecting the loosening unit to the external transmission of the upright, the rotating rod can simultaneously drive the loosening rake to rotate inside the storage tank to rake the material, avoiding material accumulation and achieving material loosening before discharge. This effectively breaks up nascent agglomerates, prevents caking and bridging, and ensures the flowability of the material. Furthermore, a dredging ring is connected to the bottom of the rotating rod via a hanging chain, so that when the rotating rod rotates, the dredging ring swings inside the guide cylinder, continuously agitating and organizing the material inside the guide cylinder. This breaks down the static friction between particles, transforming it into dynamic friction, greatly increasing the flowability. Attached Figure Description

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1-10 As shown, this embodiment provides a specific example of a refrigeration device for facilitating the use of fish swim bladder oligopeptides, and the specific implementation is as follows: A refrigeration device for facilitating the extraction of fish swim bladder oligopeptides includes a body 1, a support leg 2 fixedly connected to the bottom of the body 1, an observation window 3 fitted onto the surface of the body 1, a storage inner tank 4, a rotating rod 5, a loosening rake 6, a baffle 7, a hanging chain 8, a clearing ring 9, a guide cylinder 10, a fixed cylinder 11, a rotating cylinder 12, a metering trough 13, a gear ring 14, a gear disc 15, a vertical pole 16, a drive motor 17, a first synchronous pulley 18, a synchronous belt 19, a second synchronous pulley 20, a return spring 21, a feed cylinder 22, and a piston cylinder 2. 3. Piston head 24, piston rod 25, pressure plate 26, support spring 27, push hole 28, guide hole 29, wedge part 30, discharge port 31 and torsion spring 32. The inner storage tank 4 is fixedly installed inside the machine body 1. The bottom of the inner storage tank 4 is set in a bucket-shaped structure. The bottom end of the inner storage tank 4 is fixedly connected to the guide cylinder 10. The bottom end of the guide cylinder 10 is fixedly installed with a fixed cylinder 11. The inside of the fixed cylinder 11 is rotatably connected to a rotating cylinder 12. The inside of the rotating cylinder 12 is provided with multiple metering grooves 13 arranged in a ring at equal intervals. A gear ring 14 is sleeved on the outer wall of the rotating cylinder 12 and is rotatably connected to the inside of the fixed cylinder 11. A gear disk 15 is meshed on the outer wall of the gear ring 14 and is rotatably connected to the outside of the fixed cylinder 11. A through groove is provided on the outer wall of the fixed cylinder 11 to accommodate the meshing of the gear disk 15 and the gear ring 14. A piston cylinder 23 is fixedly connected to the top of the fixed cylinder 11, and a piston head 24 is attached to the inner wall of the piston cylinder 23. A piston rod 25 is fixedly connected to the top of the piston head 24, and a pressure plate 26 is fixedly installed on the top of the piston rod 25. The pressure plate 26 is disposed through one side of the body 1, and a support spring 27 is fixedly connected to the bottom of the pressure plate 26. The bottom of the support spring 27 is fixedly connected to the body 1. The top of the storage tank 4 is provided with a feed inlet, and a feeding unit is provided above the feed inlet. The bottom of the machine body 1 is provided with a discharge port 31, which is located below the piston cylinder 23.

[0031] The gear disk 15 is externally connected to a loosening unit, which is located inside the storage inner barrel 4. Specifically, the loosening unit includes a rotating rod 5, which is rotatably connected inside the storage inner barrel 4. Multiple loosening rakes 6 are fixedly connected to the outer wall of the rotating rod 5, and multiple hanging chains 8 are fixedly connected to the bottom end of the rotating rod 5. Each hanging chain 8 has a clearing ring 9 fixedly installed at its bottom end. The clearing ring 9 is located inside the guide cylinder 10. The end of the loosening rake 6 away from the rotating rod 5 is inclined downwards, and the outer end of the loosening rake 6 is multi-toothed.

[0032] The feeding unit includes two baffles 7, which are rotatably connected inside the feeding port and are symmetrically arranged. A torsion spring 32 is fixedly installed at the bottom of the two baffles 7. Through the arrangement of the baffles 7 and the torsion spring 32, the baffles 7 automatically close the feeding port under the elastic action of the torsion spring 32, ensuring the sealing effect above the inner storage tank 4. Moreover, through the arrangement of the torsion spring 32, when the baffles 7 are squeezed from above, the two baffles 7 can squeeze the torsion spring 32, realizing the opening of the feeding port, which facilitates the addition of material to the inner storage tank 4. Compared with the existing opening and closing of the door for material handling and addition, it reduces the interference with the internal temperature and humidity of the inner storage tank 4, while avoiding the loss of cold energy and ensuring the refrigerated quality of fish swim bladder oligopeptides.

[0033] A feeding cylinder 22 is provided above the baffle 7, and the feeding cylinder 22 is telescopically connected to the top of the machine body 1. A return spring 21 is fixedly connected to the bottom wall of the top of the feeding cylinder 22, and the bottom end of the return spring 21 is fixedly installed on the top of the machine body 1. Multiple return springs 21 are arranged circumferentially on the outer wall of the feeding cylinder 22. The bottom of the feeding cylinder 22 has two symmetrically arranged wedge-shaped parts 30, and the two wedge-shaped parts 30 are correspondingly arranged above the two baffles 7. Through the corresponding arrangement of the wedge-shaped parts 30 and the baffles 7, the baffles 7 only open the storage inner barrel 4 when the feeding cylinder 22 is pressed downward, ensuring the sealing effect inside the storage inner barrel 4, effectively isolating the outside air and moisture, and providing excellent preservation effect.

[0034] A vertical rod 16 is fixedly installed inside the gear disk 15. The vertical rod 16 is rotatably connected to the outside of the fixed cylinder 11 and is driven by a drive motor 17. Specifically, the top of the vertical rod 16 is rotatably connected to the inner top wall of the machine body 1, and the bottom end of the vertical rod 16 is fixedly installed with the output end of the drive motor 17. The drive motor 17 is fixedly installed on the outer wall of the fixed cylinder 11. Through the setting of the drive motor 17, the vertical rod 16 can drive the gear disk 15 to rotate stably. Under the meshing action of the gear disk 15 and the gear ring 14, the drive motor 17 can drive the gear ring 14 to rotate stably, ensuring the driving effect on the rotating cylinder 12, and making reasonable use of the internal space of the machine body 1. The structure is compact and highly practical. Furthermore, a first synchronous pulley 18 is fixedly connected to the top outer wall of the upright 16, and a synchronous belt 19 is fitted onto the outer wall of the first synchronous pulley 18. A second synchronous pulley 20 is also fitted onto the inner wall of the synchronous belt 19. The second synchronous pulley 20 is fixedly installed on the outer wall of the rotating rod 5 and is located at the top of the storage inner barrel 4. By setting the first synchronous pulley 18 at the top of the upright 16, the rotating rod 5 can simultaneously drive the loosening rake 6 to rotate inside the storage inner barrel 4 to rake the material, thus avoiding material accumulation and ensuring that the fish swim bladder oligopeptides are loosened inside the storage inner barrel 4, effectively preventing material accumulation and caking.

[0035] The top of the fixed cylinder 11 is provided with a guide hole 29, which is correspondingly located below the guide cylinder 10. The top of the rotating cylinder 12 is fitted with a sealing groove larger than the guide hole 29, and the sealing groove and the metering groove 13 are arranged in annular and equidistant. Through the setting of the sealing groove, the sealing groove below the guide cylinder 10 can seal the bottom of the storage inner barrel 4, effectively isolating the outside air and moisture, minimizing the loss of cold air, maintaining the internal temperature stability, and greatly improving the energy-saving effect of the refrigeration equipment. A push hole 28 is also provided through the surface of the fixed cylinder 11, and a piston is fixedly installed at the top of the push hole 28. The piston cylinder 23 has a push hole 28 located above the discharge port 31. Under the action of the push hole 28, when the piston head 24 moves inside the piston cylinder 23, the fish bladder oligopeptide powder inside the metering tank 13 is pushed downward at high speed by the piston head 24. This effectively prevents the fish bladder oligopeptide powder from "bridging" or sticking to the wall inside the metering tank 13. After the material is taken out, through the connection between the pressure plate 26 and the support spring 27, the piston head 24 can be emptied upward when it moves upward, avoiding residue inside the metering tank 13 and ensuring the accuracy of subsequent material taking out.

[0036] The working principle of this production equipment is as follows: During refrigeration, the machine body 1 is powered on, the refrigeration system is started, and the target temperature of the inner storage tank 4 is set to 4±1℃ via a button. After 2-4 hours, the internal temperature of the inner storage tank 4 stabilizes within the set range. Once the internal temperature of the inner storage tank 4 is stable, the feed cylinder 22 is pressed downwards, which compresses the return spring 21. This causes the feed cylinder 22 to press against the two baffles 7 through the wedge-shaped part 30 at the bottom. The two symmetrically arranged baffles 7 then press against the torsion spring 32, opening the inner storage tank 4 from above. This allows the user to slowly and evenly pour the fish bladder oligopeptide powder into the inner storage tank 4 through the feed cylinder 22, and observe the amount of material through the observation window 3 to ensure proper feeding. To ensure accurate material measurement, after feeding, to guarantee the sealing effect of the fish bladder oligopeptide powder inside the storage tank, the drive motor 17 drives the upright 16 to rotate. This causes the gear disc 15 to drive the rotating cylinder 12 to rotate inside the fixed cylinder 11 via the gear ring 14. The rotating cylinder 12 then drives the sealing groove to seal the bottom of the guide cylinder 10. Furthermore, through the transmission connection between the gear disc 15 and the rotating rod 5, when the gear disc 15 rotates, the rotating rod 5 simultaneously drives the loosening rake 6 to rotate inside the storage tank 4 to rake the material, preventing material accumulation. Simultaneously, the upper feeding cylinder 22 does not press against the baffle 7 when not under force, allowing the baffle 7 to seal the top of the storage tank 4, thus ensuring the fish bladder oligopeptide powder is contained within the storage tank 4. The entire part is effectively sealed, and the temperature is monitored in real time by setting the body 1 to ensure the refrigerated quality of the fish bladder oligopeptide powder. During daily use of the fish bladder oligopeptide powder, the drive motor 17 rotates the upright 16, causing the gear disc 15 to drive the rotating cylinder 12 to rotate inside the fixed cylinder 11 via the gear ring 14. This causes the rotating cylinder 12 to rotate the corresponding metering trough 13 to below the guide cylinder 10. Simultaneously, under the transmission action of the upright 16 and the rotating rod 5, the rotating cylinder 12 rotates, and the rotating rod 5 drives the loosening rake 6 to loosen the material in advance inside the storage inner barrel 4. This ensures that when the metering trough 13 rotates to below the guide cylinder 10, the fish bladder oligopeptide powder enters the metering trough 13 efficiently and accurately. After the trough 13 is full, the gear disk 15 rotates again, causing the rotating cylinder 12 to rotate the full metering trough 13 to below the piston cylinder 23. The pressure plate 26 is pressed down, causing the piston head 24 to move downward through the piston rod 25. This allows the fish bladder oligopeptide powder inside the metering trough 13 to be efficiently discharged downward through the discharge port 31 under the air pressure of the piston head 24. After the metered fish bladder oligopeptide powder is used, the gear disk 15 is driven again by the drive motor 17, causing the gear disk 15 to rotate and the gear ring 14 to rotate. This causes the rotating cylinder 12 to rotate again, causing the sealed trough to rotate to below the guide cylinder 10. This achieves resealing of the inner storage tank 4 after the material is taken out, ensuring the refrigeration quality inside the inner storage tank 4.

[0037] A refrigeration method for a refrigeration device that facilitates the access of fish swim bladder oligopeptides, applicable to such a device, includes the following steps: S1. Equipment pre-cooling: Connect the power supply to the machine body 1, start the refrigeration system, and set the target temperature of the inner storage tank 4 to 4±1℃ by pressing the button. After 2-4 hours, the internal temperature of the inner storage tank 4 will stabilize within the set range. S2, Filling the hopper: Pressing the feed cylinder 22 downwards compresses the return spring 21, causing the feed cylinder 22 to press the two baffles 7 through the wedge-shaped part 30 at the bottom. This causes the two symmetrically arranged baffles 7 to press the torsion spring 32, opening the storage inner barrel 4 from above. This allows the user to slowly and evenly pour the fish bladder oligopeptide powder into the storage inner barrel 4 through the feed cylinder 22 and observe the amount of material through the observation window 3. S3, Sealed Refrigeration: The drive motor 17 drives the upright 16 to rotate, which causes the gear disk 15 to drive the rotating cylinder 12 to rotate inside the fixed cylinder 11 through the gear ring 14. This causes the rotating cylinder 12 to drive the sealing groove to seal the bottom of the guide cylinder 10. At the same time, the upper feed cylinder 22 does not press the baffle 7 when it is not under force, so that the baffle 7 seals the top of the storage inner barrel 4. This effectively seals the fish swim bladder oligopeptide powder inside the storage inner barrel 4. The temperature is monitored in real time by setting the machine body 1. S4. Daily Use: The drive motor 17 drives the upright 16 to rotate, which in turn causes the gear disc 15 to drive the rotating cylinder 12 to rotate inside the fixed cylinder 11 via the gear ring 14. This causes the rotating cylinder 12 to rotate the corresponding metering trough 13 to the bottom of the guide cylinder 10. Simultaneously, under the transmission action of the upright 16 and the rotating rod 5, the rotating rod 5 drives the loosening rake 6 to loosen the material in advance inside the storage inner barrel 4 while the rotating cylinder 12 is rotating, ensuring that the metering trough 13 rotates to the bottom of the guide cylinder 10. When the cylinder 10 is below, the fish bladder oligopeptide powder enters the metering tank 13 efficiently and accurately. After the metering tank 13 is full, the gear disk 15 rotates again, which causes the rotating cylinder 12 to drive the full metering tank 13 to rotate below the piston cylinder 23. By pressing down the pressure plate 26, the pressure plate 26 drives the piston head 24 to move downward through the piston rod 25, so that the fish bladder oligopeptide powder inside the metering tank 13 is efficiently discharged downward through the discharge port 31 under the air pressure of the piston head 24. S5. Sealing after use: After the fish bladder oligopeptide powder is discharged, the drive motor 17 drives the gear disk 15 again, which drives the gear ring 14 to rotate, causing the rotating cylinder 12 to rotate. This causes the sealing groove to rotate again to the bottom of the guide cylinder 10, thus achieving resealing of the inner storage barrel 4 after the material is taken out, ensuring the refrigeration quality inside the inner storage barrel 4.

[0038] In summary, by setting a baffle 7 on the top of the inner storage tank 4 and sealing the bottom of the inner storage tank 4 with a closed groove inside the rotating cylinder 12, the outer air and moisture of the inner storage tank 4 are effectively isolated during refrigeration, resulting in excellent preservation. Moreover, the rotating cylinder 12 drives the quantitative trough 13 to take fish swim bladder oligopeptides from the bottom of the inner storage tank 4. The entire taking process does not require large-scale opening of the inner storage tank 4, minimizing cold air loss, maintaining stable internal temperature, and achieving good energy-saving effect. This solves the technical problem that current refrigeration equipment cannot achieve sealed refrigeration and precise quantitative taking of fish swim bladder oligopeptides.
