Description

Technical Field

[0001] This invention relates to the field of sea cucumber peptide separation equipment technology, specifically to an improvement of a centrifugal sea cucumber peptide stock solution separation device, which is particularly suitable for the efficient extraction of supernatant during the solid-liquid centrifugal separation process of sea cucumber peptide stock solution. Background Technology

[0002] Sea cucumber peptides are a core active product in the deep processing of sea cucumbers. The solid-liquid separation of the raw sea cucumber peptide solution is a crucial step in the preparation process, directly affecting the extraction purity, yield, and subsequent purification efficiency. Currently, the industry commonly uses centrifugal separation equipment for solid-liquid separation of the sea cucumber peptide raw solution. In the existing centrifugal sea cucumber peptide separation equipment, the solid-liquid stratification inside the separation cylinder exhibits specific morphological characteristics: under the combined action of the centrifugal force field distribution, the structure of the separation cylinder cavity, and the density difference between the solid and liquid phases, the sea cucumber peptide raw solution is separated into layers by utilizing the density difference of different phase materials in the centrifugal force field. The densest solid residue (sea cucumber tissue fragments, undissolved protein particles, cell debris, etc.) adheres to the inner wall of the separation cylinder under the action of centrifugal force and moves towards the bottom of the cylinder, eventually accumulating to form a conical structure with a larger bottom diameter and a smaller top diameter. The supernatant with the next lower density (containing water-soluble active ingredients such as sea cucumber peptides, free amino acids, and small molecule polysaccharides) is squeezed to the axial side of the separation cylinder, forming an inverted conical liquid layer with a gradually decreasing inner diameter from top to bottom. If the sea cucumber raw solution contains lipids, an independent oil phase layer will also be formed between the solid residue and the supernatant, achieving preliminary separation of the solid-liquid-liquid three phases.

[0003] The existing centrifugal sea cucumber peptide separation device with a fixed-position supernatant extraction guide tube is described in reference to... Figure 1 In actual industrial applications, because the installation position of the supernatant extraction guide tube is fixed, the radial distance between its lower extraction port and the inner wall of the separation tube remains constant. However, during the centrifugal separation of sea cucumber peptide stock solution, as the separation process progresses, the supernatant in the separation tube will continuously decrease due to continuous discharge. The corresponding liquid level phase of the inverted cone-shaped supernatant will gradually shift downward, and the radial boundary of the inverted cone-shaped supernatant will also contract as the liquid level shifts downward. When the supernatant level shifts to below the extraction port of the extraction guide tube, or when the radial boundary of the inverted cone-shaped supernatant contracts to the inside of the extraction port of the extraction guide tube, the extraction port of the extraction guide tube cannot contact the remaining supernatant. This means that the remaining supernatant in the separation tube cannot be introduced or discharged by the extraction guide tube and can only be discharged from the bottom impurity discharge pipe along with solid impurities. This not only causes direct waste of sea cucumber peptide supernatant but also increases the difficulty of subsequent treatment of solid impurities due to the mixing of supernatant, while reducing the overall material utilization rate of the separation process.

[0004] In summary, existing centrifugal sea cucumber peptide separation equipment suffers from technical problems due to the fixed setting of the supernatant extraction guide tube, which cannot adapt to the changes in the liquid surface and radial boundary of the inverted conical supernatant during the separation process. This results in insufficient supernatant extraction, low yield, and significant material waste. Therefore, developing a centrifugal sea cucumber peptide separation device that can adaptively adjust the extraction position according to the distribution changes of the supernatant within the separation tube, meeting the requirements of efficient, high-yield, and continuous solid-liquid separation in the sea cucumber peptide preparation process, and achieving residue-free supernatant extraction, has become an urgent technical challenge to be solved in this field. Summary of the Invention

[0005] In order to fully extract the supernatant and meet the requirements of efficient, high-yield, and continuous solid-liquid separation in sea cucumber peptide separation equipment, this application provides a sea cucumber peptide separation device.

[0006] The sea cucumber peptide separation device provided in this application adopts the following technical solution: A sea cucumber peptide separation device includes a frame, a separation cylinder mounted on the frame, a power cylinder rotatably connected to the bottom of the separation cylinder, a drive motor fixedly connected to the top of the frame, a transmission shaft fixedly connected to the output shaft of the drive motor, the transmission shaft extending from the top to the bottom of the separation cylinder and fixedly connected to the power cylinder, a receiving cylinder mounted at the top of the separation cylinder, an extraction cylinder mounted inside the receiving cylinder, the receiving cylinder, the extraction cylinder, and the separation cylinder having the same axis, a feeding channel being provided on the receiving cylinder at the top of the extraction cylinder, a drive mechanism for vertically moving the receiving cylinder and the extraction cylinder being provided at the top of the frame, and an adjustment mechanism for radially adjusting the extraction cylinder being provided inside the receiving cylinder.

[0007] By adopting the above technical solution, when using the equipment, the user adds the raw liquid into the separation cylinder, and the drive motor drives the power cylinder to rotate at high speed. Utilizing the centrifugal force generated by the rotation of the power cylinder, the supernatant forms an inverted conical distribution with a gradually decreasing inner diameter from top to bottom along the axial direction within the separation cylinder. Solid impurities adhere and accumulate along the inner wall of the separation cylinder under the action of centrifugal force. The extraction cylinder guides the supernatant to the receiving cylinder, and the supernatant in the receiving cylinder automatically flows into the receiving cylinder. As the supernatant decreases, the liquid level phase of the corresponding inverted conical supernatant gradually shifts downward, and the radial boundary of the inverted conical supernatant also contracts as the liquid level shifts downward. The drive mechanism drives the receiving cylinder and the extraction cylinder to move downward synchronously, while the adjustment mechanism drives the inner diameter of the extraction cylinder to contract, so that the extraction port of the extraction cylinder moves downward synchronously to contact the radial boundary of the supernatant liquid surface, thereby fully extracting the supernatant, reducing supernatant waste, and meeting the requirements of efficient, high-yield, and continuous solid-liquid separation in sea cucumber peptide separation equipment.

[0008] Optionally, the drive mechanism includes a first power motor fixedly connected to the top of the frame, a first threaded sleeve fixedly connected to the output shaft of the first power motor, the first threaded sleeve being rotatably connected to the frame, a first screw being threadedly connected to the inner thread of the first threaded sleeve, and the first screw being fixedly connected to the top of the receiving cylinder.

[0009] By adopting the above technical solution, when the user uses the device, the first threaded sleeve driven by the first power motor moves and rotates, driving the first screw to slide the receiving cylinder along the axial direction of the first screw. This drives the receiving cylinder and the extraction cylinder to move vertically within the separation cylinder, and then adjusts the height of the extraction cylinder according to the liquid level of the supernatant so that the supernatant is extracted more thoroughly.

[0010] Optionally, the adjustment mechanism includes a positioning ring fixedly connected to the bottom of the receiving cylinder, the extraction cylinder includes multiple guide plates with the same structure, the guide plates are arranged in an arc shape, the guide plates are distributed circumferentially along the inner diameter of the positioning ring, adjacent guide plates are sequentially overlapped to form a cylinder, the guide plates are hinged with connecting rods, and the bottom of the bearing box is provided with a power component that drives the guide plates to contract towards the center or expand away from the center.

[0011] By adopting the above technical solution, when the user uses the product, as the supernatant decreases, the radial boundary of the inverted cone-shaped supernatant will also shrink as the liquid level moves down. The first drive motor drives the receiving cylinder and the extraction cylinder to move downward synchronously, and the power component drives the guide plate to rotate towards the center, thereby causing the inner diameter of the extraction cylinder to shrink. This causes the extraction port at the bottom of the extraction cylinder to move downward synchronously until it comes into contact with the radial boundary of the supernatant liquid level, thus fully extracting the supernatant and reducing the waste of supernatant.

[0012] Optionally, the power assembly includes a fixed ring fixedly connected to the bottom of the receiving cylinder, a drive ring rotatably connected inside the fixed ring, a plurality of arc-shaped guide grooves on the drive ring, a guide post fixedly connected to the top of the connecting rod, the guide post being inserted into the guide groove and sliding within the guide groove, and the end of the connecting rod away from the guide plate being hinged to the bottom of the fixed ring; a power motor is fixedly connected to the fixed ring, a gear is fixedly connected to the output shaft of the power motor, and a rack is fixedly connected to the outer wall of the drive ring, with the gear and rack meshing.

[0013] By adopting the above technical solution, when the user uses the drive motor, after it is powered on, the drive ring is driven to rotate through the gears and racks. The drive ring, through the cooperation of the guide groove and the guide column, drives the guide plate to synchronously contract in a circular direction or synchronously expand away from the center, thereby realizing the radial adjustment of the extraction cylinder. It is adjusted according to the contraction or expansion of the radial boundary of the supernatant, so that the extraction port at the bottom of the extraction cylinder is always in contact with the interface between the supernatant and solid impurities.

[0014] Optionally, the receiving cylinder is fixedly connected to an annular baffle at the bottom of the feeding channel, and the bottom of the baffle is lower than the positioning ring.

[0015] By adopting the above technical solution, when the power motor drives the guide plate to expand or contract outward, a gap is formed between the guide plate and the positioning ring. The baffle can block the gap and prevent the supernatant guided upward by the guide plate from flowing back into the separation cylinder through the gap.

[0016] Optionally, the inner wall of the baffle is provided with multiple axial grooves, and the baffle is made of rubber material.

[0017] By adopting the above technical solution, the rubber itself has excellent elasticity when used by the user. The inner wall has a flexible axial groove. The core function of the axial groove is to reduce radial stiffness, release stress, and improve the flexibility of expansion and contraction, so that the radial expansion and contraction range of the baffle can reach 30%~100%. The axial groove avoids local stress concentration in the material during large deformation, while maintaining the integrity of the baffle seal.

[0018] Optionally, a collecting cylinder is provided at the top of the separating cylinder, a relief groove is provided in the middle of the collecting cylinder, a receiving cylinder is located in the relief groove, an overflow channel is provided in the middle of the inner wall of the collecting cylinder, the overflow channel facilitates the automatic entry of the oil phase layer into the collecting cylinder, and a guide pipe is connected to the collecting cylinder.

[0019] By adopting the above technical solution, when the user uses the system, the collection cylinder is used to automatically collect the oil phase layer, and the feed pipe is used to discharge the collected oil phase layer to the outside.

[0020] Optionally, a second power motor is fixedly connected to the top of the frame, and a second threaded sleeve is fixedly connected to the output shaft of the second power motor. The second threaded sleeve is rotatably connected to the frame, and a second screw is threadedly connected to the inner thread of the second threaded sleeve. The first screw is fixedly connected to the top of the collecting cylinder.

[0021] By adopting the above technical solution, when the user uses the device, the second threaded sleeve driven by the second power motor moves and rotates, driving the second screw to slide the receiving cylinder along the axial direction of the second screw. This drives the collecting cylinder to move vertically inside the separation cylinder, and the height of the collecting cylinder can be adjusted according to the liquid level of the oil phase layer so that the oil phase layer can be extracted more thoroughly.

[0022] Optionally, the side wall of the separating cylinder is hinged with a door, one side of the door is hinged to the separating cylinder by a hinge, a buckle is fixedly connected to one side of the door, the buckle is provided with a notch, and two threaded posts are hinged to the side wall of the separating cylinder, and chucks are threadedly connected to the threaded posts.

[0023] By adopting the above technical solution, when using the device, the user rotates the threaded column to make it engage with the notch groove of the buckle, and then tightens the chuck to make it abut against the buckle, which can fix the box door and the separator cylinder. The box door can be opened to facilitate the cleaning of the residue and inner wall of the separator cylinder. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0029] This application provides an embodiment of a sea cucumber peptide separation device, referring to... Figure 2 and Figure 3 The system includes a frame 1, a separating cylinder 2 mounted on the frame 1, a feed pipe 22 at the bottom of the separating cylinder 2 with a solenoid valve on the feed pipe 22, a power cylinder 21 rotatably connected to the bottom of the separating cylinder 2, a drive motor 26 fixed at the top of the frame 1, the output shaft of the drive motor 26 connected to a transmission shaft 261, the transmission shaft 261 extending from the top to the bottom of the separating cylinder 2 and fixed to the power cylinder 21, and rotatably connected to the frame 1 at the bottom, a receiving cylinder 3 at the top of the separating cylinder 2, an extraction cylinder 4 inside the receiving cylinder 3, the receiving cylinder 3, the extraction cylinder 4 and the separating cylinder 2 having the same axis, a feed channel 31 at the top of the receiving cylinder 3 at the top of the extraction cylinder 4, a discharge pipe 32 at the top of the receiving cylinder 3 extending into the receiving cylinder 3, a solenoid valve on the discharge pipe 32, a drive mechanism 6 at the top of the frame 1 for vertical movement of the receiving cylinder 3 and the extraction cylinder 4, and an adjustment mechanism 7 inside the receiving cylinder 3 for radial adjustment of the extraction cylinder 4. This structural design allows the equipment to adaptively adjust according to the distribution changes of the supernatant in the separation cylinder 2, fully extracting the supernatant, reducing waste, and meeting the requirements of efficient, high-yield, and continuous solid-liquid separation.

[0030] Specifically, the frame 1 serves as the supporting foundation for the entire equipment, typically made of metal, possessing sufficient strength and stability to support other components. The separation cylinder 2 is the main site for solid-liquid separation of the sea cucumber peptide stock solution; it is generally cylindrical in shape and can be made of corrosion-resistant materials such as stainless steel. The feed pipe 22 is used to transport the stock solution into the separation cylinder 2, and a solenoid valve controls the on / off state of the feed, facilitating operation and controlling the feed rate.

[0031] The power cylinder 21 is installed at the bottom inside the separator cylinder 2 and is connected to the drive shaft 261. It rotates at high speed under the drive of the drive motor 26. The drive motor 26 is generally a high-performance motor, which can provide sufficient power to generate a strong centrifugal force in the power cylinder 21. The drive shaft 261 plays the role of transmitting power. It extends from the top to the bottom of the separator cylinder 2 and is rotatably connected to the frame 1 at the bottom to ensure the stability of rotation.

[0032] A door 23 is hinged to the side wall of the separator 2. One side of the door 23 is hinged to the separator 2, and the other side of the door 23 is fixedly connected to a buckle 231 with a notch 232. Two threaded posts 24 are hinged to the side wall of the separator 2, and chucks 25 are threaded onto the threaded posts 24. Specifically, the door 23 facilitates the cleaning of residue and the inner wall of the separator 2. The hinge ensures the flexible opening and closing of the door 23. When it is necessary to close the door 23, rotate the threaded post 24 so that it engages with the notch 232 of the buckle 231, and then tighten the chuck 25 so that it abuts against the buckle 231, thus fixing the door 23 to the separator 23. When cleaning is required, release the chuck 25, rotate the threaded post 24 to disengage from the buckle 231, and the door 23 can be opened.

[0033] The design of the enclosure door 23 makes equipment maintenance and cleaning more convenient. Through the simple cooperation of the threaded post 24 and the chuck 25, the enclosure door 23 can be quickly fixed and opened, improving the maintainability of the equipment and ensuring its long-term stable operation.

[0034] Refer to 4 and Figure 5 The receiving cylinder 3, located at the top inside the separating cylinder 2, receives the supernatant from the extraction cylinder 4. It can be a cylindrical body made of a similar material to the separating cylinder 2. The extraction cylinder 4 inside the receiving cylinder 3 is a key component, responsible for guiding the supernatant into the receiving cylinder 3. The extraction cylinder 4 is also cylindrical, aligned with the axis of the receiving cylinder 3 and the separating cylinder 2, ensuring smooth flow. The feed channel 31, located at the top of the extraction cylinder 4, is the channel through which the supernatant enters the receiving cylinder 3. The discharge pipe 32 discharges the supernatant from the receiving cylinder 3, and a solenoid valve on the discharge pipe 32 controls the flow of the discharge.

[0035] The drive mechanism 6 is used to drive the vertical movement of the receiving cylinder 3 and the extraction cylinder 4. In this embodiment, the drive mechanism 6 includes a first power motor 61 fixedly connected to the top of the frame 1. Two first power motors 61 are shown in the figure. A first threaded sleeve 62 is fixedly connected to the output shaft of each motor. The first threaded sleeve 62 is rotatably connected to the frame 1. A first screw 63 is internally threaded onto the first threaded sleeve 62, and the first screw 63 is fixedly connected to the top of the receiving cylinder 3. The first power motor 61 drives the first threaded sleeve 62 to rotate. Through threaded transmission, the first screw 63 drives the receiving cylinder 3 to slide along the axial direction of the first screw 63, thereby realizing the vertical movement of the receiving cylinder 3 and the extraction cylinder 4 within the separation cylinder 2. The first power motor 61 can be a stepper motor, which has precise control performance and can accurately adjust the height of the extraction cylinder 4 according to the liquid level of the supernatant. The fit between the first threaded sleeve 62 and the first screw 63 must be high to ensure smooth movement.

[0036] Reference Figure 4 and Figure 6 The adjusting mechanism 7 is used to drive the extraction cylinder 4 to adjust radially. The adjusting mechanism 7 includes a positioning ring 71, a guide plate 41, a connecting rod 72, and a power component 73. The positioning ring 71 is fixedly connected to the bottom of the receiving cylinder 3. The guide plates 41 are arranged in an arc shape and are distributed circumferentially along the inner diameter of the positioning ring 71. Adjacent guide plates 41 are sequentially overlapped to form a cylinder. The connecting rod 72 is hinged to the guide plate 41. The power component 73 is used to drive the guide plate 41 to contract towards the center or expand away from the center. The power assembly 73 includes a fixed ring 731 fixedly connected to the bottom of the receiving cylinder 3, a drive ring 732 rotatably connected inside the fixed ring 731, a plurality of arc-shaped guide grooves 733 opened on the drive ring 732, a guide post 721 fixedly connected to the top of the connecting rod 72, the guide post 721 being inserted into the guide groove 733 and being able to slide within the guide groove 733, and the end of the connecting rod 72 away from the guide plate being hinged to the bottom of the fixed ring 731; a power motor 735 fixedly connected to the fixed ring 731, a gear 736 fixedly connected to the output shaft of the power motor 735, and a rack 734 fixedly connected to the outer side wall of the drive ring 732, the gear 736 and the rack 734 meshing. After the power motor 735 is powered on, it drives the drive ring 732 to rotate via the gear 736 and rack 734. The drive ring 732, through the cooperation of the guide groove 733 and guide post 721, drives the guide plate 41 to synchronously contract in a circular direction or synchronously expand away from the center, thereby achieving radial adjustment of the extraction cylinder 4. The power motor 735 can be a servo motor, capable of precisely controlling the rotation angle of the drive ring 732, and thus precisely adjusting the inner diameter of the extraction cylinder 4. The cooperation between the guide groove 733 and the guide post 721 must be smooth to ensure the flexibility of the guide plate 41's movement.

[0037] When using the equipment, the user first adds the raw liquid into the separator 2 through the feed pipe 22 and opens the solenoid valve on the feed pipe 22 to control the feed rate. Then, the drive motor 26 is started, which drives the transmission shaft 261 to rotate. The transmission shaft 261 drives the power cylinder 21 to rotate at high speed. Using the centrifugal force generated by the rotation of the power cylinder 21, the supernatant forms an inverted cone shape with a gradually decreasing inner diameter along the axial direction from top to bottom in the separator 2. Solid impurities adhere and accumulate along the inner wall of the separator 2 under the action of centrifugal force. The extraction cylinder 4 guides the supernatant into the receiving cylinder 3, and the supernatant in the receiving cylinder 3 is discharged through the discharge pipe 32. The solenoid valve on the discharge pipe 32 is opened to control the discharge. As the supernatant decreases, the liquid level phase of the corresponding inverted cone-shaped supernatant will gradually shift downward, and the radial boundary of the inverted cone-shaped supernatant will also shrink as the liquid level shifts downward. At this time, the first power motor 61 of the drive mechanism 6 starts, driving the first threaded sleeve 62 to rotate. The first threaded sleeve 62 drives the first screw 63 to move the receiving cylinder 3 and the extraction cylinder 4 downward synchronously. At the same time, the power motor 735 of the adjustment mechanism 7 starts, driving the drive ring 732 to rotate through the gear 736 and rack 734. The drive ring 732 drives the guide plate 41 to contract towards the center through the guide groove 733 and guide column 721, causing the inner diameter of the extraction cylinder 4 to contract. The extraction port of the extraction cylinder 4 moves downward synchronously to contact the radial boundary of the supernatant liquid surface, thereby fully extracting the supernatant, reducing the waste of supernatant, and meeting the requirements of efficient, high-yield, and continuous solid-liquid separation in the sea cucumber peptide separation equipment.

[0038] A ring-shaped baffle 33 is fixedly connected to the bottom of the receiving cylinder 3 at the bottom of the feeding channel 31. The bottom of the baffle 33 is lower than the positioning ring 71. The baffle 33 is made of rubber material, and its inner wall has multiple axial grooves 331. The function of the baffle 33 is to prevent the supernatant from flowing back. When the power motor 735 drives the guide plate 41 to expand or contract outward, a gap will be formed between the guide plate 41 and the positioning ring 71. The baffle 33 can block this gap, preventing the supernatant guided upward by the guide plate 41 from flowing back into the separation cylinder 2 through the gap. The rubber material has good elasticity and can better adapt to the radial changes of the extraction cylinder 4. The axial grooves 331 on the inner wall can reduce radial stiffness, release stress, and improve the flexibility of expansion and contraction, so that the radial expansion and contraction range of the baffle 33 can reach a certain range, avoiding local stress concentration of the material during large deformation, while maintaining the integrity of the seal of the baffle 33.

[0039] The baffle 33 effectively prevents the backflow of the supernatant, ensuring the effectiveness of supernatant collection. The design of the rubber material and the axial groove 331 allows the baffle 33 to maintain good sealing performance when the extraction cylinder 4 is radially adjusted, adapting to dynamic changes in the equipment and further improving the reliability of the equipment and the collection efficiency of the supernatant.

[0040] A collecting cylinder 5 is installed at the top of the separating cylinder 2. The outer diameter of the collecting cylinder 5 is the same as the inner diameter of the separating cylinder 2. A relief groove 51 is opened in the middle of the collecting cylinder 5, and the receiving cylinder 3 is located in the relief groove 51. An overflow channel 52 is opened in the middle of the inner wall of the collecting cylinder 5, which facilitates the automatic entry of the oil phase layer into the collecting cylinder 5. A guide pipe 53 is connected to the collecting cylinder 5, and the guide pipe 53 extends into the interior of the collecting cylinder 5. A solenoid valve is installed on the guide pipe 53. A second power motor 54 is fixedly connected to the top of the frame 1. There are two second power motors 54. A second threaded sleeve 55 is fixedly connected to the output shaft of the second power motor 54. The second threaded sleeve 55 is rotatably connected to the frame 1. A second screw 56 is threadedly connected to the inner thread of the second threaded sleeve 55. The second screw 56 is fixedly connected to the top of the collecting cylinder 5.

[0041] Specifically, the collecting cylinder 5 is used to collect the oil phase layer generated during the separation process. Its outer diameter is the same as the inner diameter of the separating cylinder 2, ensuring installation stability. The clearance groove 51 provides installation space for the receiving cylinder 3, making the equipment structure more compact. The overflow channel 52 allows the oil phase layer to automatically flow into the collecting cylinder 5, facilitating its collection. The feed pipe 53 is used to discharge the collected oil phase layer outwards, and the solenoid valve on the feed pipe 53 can control the discharge of the oil phase layer.

[0042] The second power motor 54 drives the second threaded sleeve 55 to rotate, and the second threaded sleeve 55 drives the second screw 56 to slide the collecting cylinder 5 along the axial direction of the second screw 56. This allows the collecting cylinder 5 to move vertically within the separating cylinder 2, and the height of the collecting cylinder 5 can be adjusted according to the liquid level of the oil phase to ensure more thorough extraction of the oil phase. The second power motor 54 can also be a stepper motor to ensure precise control.

[0043] The implementation principle of this embodiment is as follows: This sea cucumber peptide separation equipment, through its ingenious structural design, utilizes centrifugal force to achieve solid-liquid separation of the sea cucumber peptide stock solution. The vertically and radially adjustable extraction cylinder 4 can adaptively adjust according to changes in the distribution of the supernatant, fully extracting the supernatant, reducing waste, and improving separation efficiency and yield. Precise control of the drive mechanism 6 and the adjustment mechanism 7 ensures the stability and reliability of the equipment. Compared with existing technologies, it better meets the needs of industrial production and improves the overall quality and efficiency of the sea cucumber peptide preparation process.

[0044] The structure of the collection cylinder 5 and its adjustable height enables the equipment to effectively collect the oil phase layer. Driven vertically by the second motor 54, the collection cylinder 5 can adaptively adjust according to the liquid level of the oil phase layer, fully collecting the oil phase layer and preventing it from mixing with the supernatant or solid impurities. This further improves the purity and efficiency of the separation, meeting the requirements for solid-liquid-liquid three-phase separation in the sea cucumber peptide separation process.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
