Description

Technical Field

[0001] The invention relates to the technical field of aquatic product processing, in particular to ultra-low temperature mussel shelling processing equipment. Background Art

[0002] Mussels are widely welcomed for their rich nutritional value and delicious taste. During the processing, shelling is an important step in mussel processing. Existing technologies mainly use mechanized means or manual operations to achieve shelling. The manual shelling method relies on the operator to peel the mussels, which has certain flexibility and precision and is suitable for small-scale production. The mechanized shelling equipment improves the processing efficiency through extrusion, impact or cutting, and combines conveyor belts and separators to achieve a certain degree of automation. These technologies have achieved good results in practice and provide a basis for large-scale processing. However, due to the special structure of mussels and the close connection between their flesh and shells, the existing technology still has room for further optimization in some links.

[0003] For example, although mechanical extrusion and impact shelling methods have improved efficiency, it is difficult to fully protect the quality of mussel meat, and some mussel meat may be damaged during operation. In addition, during the mussel transportation process, due to the lack of a reasonable evenly distributed design on the conveyor belt, mussels tend to accumulate in certain positions, which may lead to unevenness during the processing and affect the shelling effect. At the same time, for separation and quantitative processing, mussels of different sizes require flexible adjustment of the equipment, and some existing technical means have certain limitations in quickly adapting to processing of different specifications. Overall, the existing technology provides a reliable foundation for mussel shelling processing, but there is still room for further improvement in terms of meat protection, evenly distributed processing and quantitative flexibility.

[0035] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a mussel ultra-low temperature shelling processing device, comprising:

[0037] The frame 1 is used as the overall frame of the equipment to form a closed space required for freezing;

[0038] A quantitative mechanism 2, which is arranged on the top of the frame 1 and is used to quantitatively transport the poured mussels out;

[0039] A shelling mechanism 3, which is arranged on one side of the frame 1 and is used for quickly shelling frozen mussels;

[0040] A refrigeration mechanism 4, which is arranged inside the frame 1 and is used for rapidly freezing the mussels;

[0041] An even distribution mechanism 5, which is arranged at the bottom of the quantitative mechanism 2 and is used to evenly distribute the transported mussels;

[0042] A conveyor belt 6, which is arranged at the bottom of the spreading mechanism 5 and is used to transport the mussels after quantitative delivery;

[0043] A collecting box 8, which is arranged on one side of the shelling mechanism 3 and is used to collect the shelled mussels together with their shells for subsequent sorting;

[0044] The quantitative mechanism 2 includes a feed hopper 21, a weighing tank 22 is fixed at the bottom of the feed hopper 21, a discharge pipe 23 is fixed at the bottom of the weighing tank 22, a motor 27 is arranged on one side of the weighing tank 22, a driving shaft 28 is fixed at the output end of the motor 27, a rotating column 24 is slidably arranged on the outer wall of the driving shaft 28, a partition plate 25 distributed in a ring array is fixed on the outer wall of the rotating column 24, a turntable 26 is rotatably connected to one side of the rotating column 24, and the turntable 26 is threadedly connected to the inside of the weighing tank 22.

[0045] Specifically, when it is necessary to shell the mussels, all the mussels should first be poured into the device from the feed hopper 21. At this time, the mussels will smoothly enter the internal space of the portion tank 22. At this time, the motor 27 starts to operate normally, driving the rotating column 24 to rotate through the drive shaft 28. As the rotating column 24 rotates, the partition plate 25 installed thereon will rotate with the rotating column 24 as the center of the circle, thereby separating the incoming mussels into relatively uniform units according to a certain amount. Such a separation process is both fast and efficient, and can avoid the accumulation or uneven distribution of mussels.

[0046] It is worth noting that when processing mussels of different sizes, in order to better adapt to the overall size distribution of mussels, the turntable 26 can be adjusted to drive the rotating column 24 to separate from the driving shaft 28. Subsequently, the rotating column 24 and the partition plate 25 adapted to the new separation space size can be replaced to achieve quantitative separation of mussels of different sizes. This design greatly improves the adaptability and flexibility of the equipment, allowing the equipment to efficiently process mussels of different sizes.

[0047] After the quantitative separation is completed, the mussels are transported to the surface of the conveyor belt 6 through the discharge pipe 23. The conveyor belt 6 is driven by the driving roller 7 to smoothly transport the mussels to the next processing stage. During the transportation process, the spreading mechanism 5 can further ensure that the mussels are evenly distributed on the surface of the conveyor belt 6 to avoid accumulation and blockage.

[0048] The entire separation process is carried out under the automatic control of the equipment, and the operation is simple and stable. In particular, during separation, the function of rapid adjustment by rotating the turntable 26 not only improves the processing efficiency, but also reduces the equipment downtime when replacing different separation components. In addition, during the discharge process, the linkage design of the vibration box 31 and the conveyor belt 6 of the equipment further improves the smoothness of mussel transportation and effectively avoids the problem of blockage during transportation.

[0049] Please refer to the attached Figure 2 The balancing mechanism 5 includes a driving seat 51, which is arranged inside the frame 1. The driving seat 51 is connected to a connecting rod 1 52 through an internal automatic electric shaft. A connecting rod 2 53 is rotatably provided at one end of the connecting rod 1 52, and a connecting block 54 is rotatably provided at one end of the connecting rod 2 53. A rotating column 2 55 is rotatably provided inside the connecting block 54. A provoking rod 56 distributed in a circular array is fixed to the outer wall of the rotating column 2 55. A plurality of driving rollers 7 are arranged inside the conveyor belt 6. A belt 58 is arranged between one end of a driving roller 7 and one end of the rotating column 2 55 through a pulley. An elastic rod 59 is arranged inside the belt 58. The outer wall of the elastic rod 59 is fitted with the belt 58. An electric push rod 2 57 fixed to the frame 1 is arranged on one side of the belt 58, and the output end of the electric push rod 2 57 is fixed to the outer wall of the elastic rod 59.

[0050] Specifically, the surface of the conveyor belt 6 is designed with evenly arranged partitions 25, which can divide the mussels transported from the discharge pipe 23 into rows, effectively avoiding the mussels from randomly piling up on the conveyor belt 6, thereby ensuring the orderliness of subsequent transportation and processing. However, for some mussels that are piled up during the transportation process, the system is also equipped with an ingenious dispersion structure. When the conveyor belt 6 is running, the driving roller 7 it relies on not only drives the conveyor belt 6 forward, but also connects and drives the rotating column 2 55 through the belt 58 to rotate synchronously. The rotation of the rotating column 2 55 will drive the stirring rod 56 set thereon to continuously swing and stir, quickly breaking up the accumulated mussels, avoiding large-area accumulation that affects the smoothness of transportation, thereby achieving smooth dispersion and transportation of the mussels.

[0051] In order to adapt to mussels of different sizes, the height of this dispersing device can be flexibly adjusted, and its adjustment mechanism is realized by the driving seat 51. When the height of the rotating column 2 55 needs to be changed, the driving seat 51 will drive the connecting rod 1 52 to rotate, and change the inclination angle of the connecting rod 1 52 with the driving seat 51 as the center. The angle change of the connecting rod 1 52 will further affect the movement of the connecting rod 2 53. Due to the connection relationship between the two, the connecting rod 2 53 will synchronously push and pull. This movement will directly drive the connecting block 54, thereby driving the overall lifting and lowering adjustment of the rotating column 2 55 to achieve the height change of the dispersing device.

[0052] Through the above-mentioned adjustment function, the height and angle of the stirring rod 56 can be flexibly adjusted according to the size and shape of the mussels, making the dispersion action more accurate and efficient. For example, for larger mussels, the increase in height allows the stirring rod 56 to better contact and disperse the accumulated mussels; while for smaller mussels, the lowering of the stirring rod 56 can avoid the stirring action being too violent and causing the mussels to be scattered. Such a design ensures that no matter what the size of the mussels is, the accumulation phenomenon can be effectively dispersed and will not interfere with the normal transportation of the conveyor belt 6.

[0053] It is worth mentioning that the movement of this dispersing mechanism is smooth and precise, and combined with the function of the uniform partition plate 25 of the conveyor belt 6, the mussel transportation process is more efficient. In actual work, whether the mussels are of different sizes or the transportation speed is fast, the dispersing device can respond quickly, and the piled mussels can be dispersed through the flexible stirring of the stirring rod 56, and finally the stability and continuity of the entire transportation link are guaranteed. At the same time, the adjustment method of this mechanism is simple and easy to operate, which can greatly reduce the frequency of manual intervention and improve the overall automation level and processing efficiency of the equipment.

[0054] Please refer to the attached Figure 1 , Attachment Figure 5 and attached Figure 6 An electric door 9 controlled by an electric guide rail is arranged on one side of the frame 1, and the shelling mechanism 3 includes a vibration box 31, a gas tank 32 is fixed on one side of the vibration box 31, an air pump is arranged inside the gas tank 32, and is connected to the air pressure block 33 through an air pipe, the air pressure block 33 is arc-shaped, and the air port is located just above the vibration box 31, and an oscillation plate 34 with a certain inclination angle slides inside the vibration box 31, and a motor 2 35 is arranged on one side of the vibration box 31, and a gear 1 36 is fixed to the output end of the motor 2 35 through a rotating shaft, and a gear 2 37 is arranged on one side of the gear 1 36, and the gear 1 36 is meshed with the gear 2 37, and the gear 2 37 is connected to a turntable 2 38 through a rotating shaft, and the turntable 2 38 is connected to a connecting plate 39 through a rotating shaft away from the center of the circle, and one end of the connecting plate 39 is connected to one side of the oscillation plate 34 through a rotating shaft.

[0055] Specifically, the frozen mussels will be transported to the vibration box 31 through the conveyor belt 6, and finally fall to the position above the vibration plate 34. At this time, the motor 2 35 is started to drive the entire vibration mechanism into working state. The power of the motor 2 35 is transmitted to the gear 2 37 through the gear 1 36, so that the gear 2 37 rotates in the opposite direction. The movement of the gear 2 37 further drives the turntable 2 38 to rotate synchronously. Since the turntable 2 38 is an eccentric design, its rotation will cause the two ends of the connecting plate 39 to produce a reciprocating pulling action. This pulling action will drive the vibration plate 34 to vibrate in the up and down or left and right directions, thereby ensuring the effective movement of the vibration plate 34.

[0056] As the vibration plate 34 vibrates back and forth, the mussels on its surface will be subjected to certain impact and vibration force. This vibration will gradually separate the shell and meat of the frozen mussels, achieving the final shelling effect. During the vibration process, the shell of the mussel is peeled off due to the vibration force, while the mussel meat remains intact and slides along the tilt angle of the vibration plate 34. The tilted design ensures that the mussels can slide smoothly after separation, and will not stay or accumulate due to the planar movement of the vibration plate 34.

[0057] At the same time, the tilt angle of the vibration plate 34 allows the separated mussel meat and shell to slide naturally to the lower part of the plate during vibration. When the vibration plate 34 continues to vibrate under the vibration effect brought by the eccentric movement of the turntable 2 38, the separated mussels will slide along the tilted surface to the collection box 8 for collection. The setting of the collection box 8 makes the subsequent classification and collection of mussel shells and meat more efficient, and the whole process does not require manual intervention and is fully automated.

[0058] This shelling design is not only compact and stable in operation, but also can achieve efficient processing for mussels of different sizes and hardness. The airtight design of the vibration box 31, combined with the tilting and vibration functions of the vibration plate 34, ensures that the mussels will not bounce or scatter during the vibration process, while avoiding the separation efficiency from external interference. In addition, by optimizing the transmission ratio of gear 1 36 and gear 2 37, the frequency and amplitude of the vibration of the vibration plate 34 can be accurately controlled to meet the needs of shell and meat separation of different mussels, further improving the adaptability and efficiency of the equipment.

[0059] The entire shelling process operates smoothly and efficiently, especially the back and forth vibration generated by the vibration plate 34 in cooperation with the connecting plate 39, which can not only ensure the thoroughness of shelling, but also protect the integrity of the mussel meat to the maximum extent. Finally, the separated mussel meat is quickly collected in the receiving box 8, and the separation of shell and meat is successfully completed. This precise design and efficient working principle provide a solid technical guarantee for the operation of the entire equipment, while greatly reducing the need for manual operation and significantly improving production efficiency.

[0060] Please refer to the attached Figure 2 and attached Figure 7 The refrigeration mechanism 4 includes an electric push rod 42, which is arranged inside the frame 1. A closed door 41 is fixed to the output end of the electric push rod 42. The closed door 41 slides inside the frame 1 and the closed doors 41 on both sides can be fitted together. A compressor 43 is arranged inside the frame 1. The compressor 43 is connected to a condenser 44 through an air pipe. Multiple rows of condensing tubes are arranged inside the condenser 44, and an expansion valve 45 is connected to the condenser 44 through the air pipe. The expansion valve 45 is connected to the evaporator 46 through the air pipe.

[0061] Specifically, after the mussel sorting operation is completed, the equipment enters the next step. At this time, the electric push rod 42 is activated, pushing the closed door 41 to slide smoothly along the slide rail. This design ensures that the separated mussels are evenly transported to the conveyor belt 6 in batches. The conveyor belt 6 accurately transports the mussels to the position of the refrigeration mechanism 4 inside the rack 1. The whole process has a high degree of automation and runs smoothly, avoiding the unevenness and errors that may be caused by manual intervention.

[0062] When a batch of mussels arrives at the processing area of ​​the refrigeration mechanism 4, the closed door 41 is closed again by the electric push rod 42 to form a closed space, creating an ideal working environment for the subsequent refrigeration process. At this stage, the refrigeration system starts to operate, and its core working principle is based on the cyclic refrigerant change process.

[0063] First, low-temperature and low-pressure refrigerant vapor is sucked from the evaporator 46 by the compressor 43 and compressed into high-temperature and high-pressure superheated vapor in the compressor 43. Subsequently, these high-temperature and high-pressure refrigerant vapors enter the condenser 44, where they exchange heat with an external cooling medium such as air or cooling water. Through heat exchange, the refrigerant vapor releases a large amount of heat and condenses into a high-pressure liquid state. This process is not only efficient but also stable, providing a basis for the subsequent refrigeration process.

[0064] Next, the high-pressure liquid refrigerant passes through the expansion valve 45. The throttling effect of the expansion valve 45 rapidly reduces the pressure of the refrigerant, converting it into a low-temperature and low-pressure liquid and gas mixture. The low-temperature and low-pressure refrigerant at this time is sent back to the evaporator 46. In the evaporator 46, the refrigerant absorbs heat from the surrounding mussels and the environment, gradually and completely vaporizes into low-pressure steam, and is sucked into the compressor 43 again to enter the next cycle.

[0065] This cycle rapidly lowers the temperature of the refrigeration area through efficient heat transfer, allowing the mussels to be quickly frozen. The advantage of rapid freezing is that the binding tissue between the mussel shell and the flesh shrinks rapidly under low temperature conditions due to the thermal expansion and contraction characteristics, thereby achieving a natural separation of the shell and the flesh. This method not only improves the separation efficiency, but also effectively maintains the quality and freshness of the mussel meat.

[0066] The entire refrigeration and shelling process is efficient and automated, and every step reflects the application of rigorous mechanical design and thermodynamic principles, which greatly improves the efficiency of mussel processing and the quality of the finished product. At the same time, the closedness and precision of this structure ensure the consistency of the refrigeration effect and avoid unnecessary energy consumption caused by heat loss.

[0067] Example 2: Automatic control system for mussel shelling device

[0068] System composition

[0069] The control system consists of the following modules:

[0070] Central control module PLC or industrial controller: As the core control unit, it is used to receive sensor signals, analyze data, and issue control instructions to drive the actuator to operate.

[0071] Detection module: includes temperature sensor, pressure sensor, position sensor and weight sensor, which are used to collect operation data of mussel processing in real time.

[0072] Execution module: includes electric push rod, motor 2, compressor 43, condenser 44, expansion valve 45, evaporator 46 and conveyor belt 6 driving roller 7 to complete specific operation actions.

[0073] Display and alarm module: provides visual monitoring of system operation status and issues alarm signals in abnormal situations.

[0074] When the mussels enter the weighing tank 22 from the feed hopper 21, the weight sensor detects the weight of the mussels in the tank in real time. When the weight reaches the set value, such as 2 kg, the weight sensor sends a signal to the central control module. After receiving the signal, the central control module issues a command to start the motor 27, drive the rotating column 24 to rotate, and cooperate with the partition plate 25 to separate the mussels into uniform batches.

[0075] Judgment conditions:

[0076] Weight sensor signal>preset value 2 kg: start motor 27.

[0077] Weight sensor signal < preset value: Waiting for mussels to be filled.

[0078] After the separation is completed, the separated mussels enter the conveyor belt 6 through the discharge pipe 23. The position sensor detects that the mussels have entered the conveyor belt 6 and sends a confirmation signal to the central control module. At this time, the conveyor belt 6 drive roller 7 starts to operate and transports the mussels to the refrigeration mechanism 4 inside the rack 1.

[0079] 2. Mussel freezing control by refrigeration mechanism 4

[0080] After the mussels are transported to the refrigeration mechanism 4, the position sensor detects that the mussels have reached the refrigeration area and sends a signal to the central control module. The central control module issues a command to drive the electric push rod 1 42 to close the closed door 41, forming a closed refrigeration environment.

[0081] After the refrigeration system is started, the compressor 43 starts working, and the low-temperature and low-pressure refrigerant vapor is sucked from the evaporator 46 and compressed into high-temperature and high-pressure superheated vapor. The condenser 44 converts the vapor into a high-pressure liquid, and then reduces the pressure through the expansion valve 45 to become a low-temperature and low-pressure liquid and gas mixture. The evaporator 46 absorbs the heat of the cooling medium mussels, causing the mussels to freeze rapidly.

[0082] The temperature sensor is installed in the evaporator 46 and the refrigeration chamber to detect the temperature of the refrigeration chamber in real time. When the temperature drops to a preset value such as -25°C, the temperature sensor sends a signal to the central control module, and the central control module controls the compressor 43 to reduce power or stop working to keep the temperature in the refrigeration chamber constant.

[0083] Judgment conditions:

[0084] Temperature sensor signal>-25°C: compressor 43 works.

[0085] Temperature sensor signal ≤-25°C: compressor 43 stops working and enters a constant temperature state.

[0086] After the freezing is completed, the central control module instructs the electric push rod 42 to reopen the closed door 41, and the conveyor belt 6 starts to transport the frozen mussels to the evenly spreading mechanism 5.

[0087] 3. Shelling and amortization control

[0088] After the frozen mussels are transported to the evenly distributed mechanism 5, the vibration plate 34 of the vibration box 31 is started under the drive of the motor 2 35 to generate high-frequency vibration, so that the mussels are evenly distributed on the surface of the conveyor belt 6. This process ensures that the mussels are neatly arranged when entering the shelling mechanism 3 to avoid stacking or missing.

[0089] Judgment conditions:

[0090] The position sensor detects that the mussels enter the averaging mechanism 5: the vibration box 31 is started.

[0091] Conveyor belt 6 speed control signal: The central control module adjusts the speed of the drive roller 7 according to the mussel batch flow rate.

[0092] After the mussels are evenly distributed, they enter the shelling mechanism 3. In the shelling mechanism 3, the vibration plate 34 and the air pressure block 33 act alternately, and through appropriate vibration and air pressure shock, the frozen mussel shells are separated from the flesh. After the separation is completed, the shells and the flesh are respectively transported to different receiving boxes 8.

[0093] 4. System monitoring and alarm

[0094] During the whole process, the central control module monitors the following parameters in real time:

[0095] Temperature: Temperature sensors monitor the temperature of the refrigeration chamber and refrigerant.

[0096] Pressure: The pressure sensor detects the pressure of the refrigerant pipeline.

[0097] Position: The position sensor monitors the status of the closing door 41 and the conveyor belt 6.

[0098] Weight: The weight sensor monitors the weight of the material in the batch tank 22.

[0099] When any parameter exceeds the preset range, for example, the pressure is higher than the safety value, the temperature does not meet the freezing requirements, the closed door 41 cannot be closed, etc., the central control module triggers the alarm module, sends out an audible and visual alarm, and automatically shuts down. At the same time, the display module displays fault information such as "abnormal pressure" or "closed door 41 failure" to facilitate operators to handle in time.

[0100] Judgment conditions:

[0101] Pressure > safety range: alarm and shutdown.

[0102] If the temperature does not meet the standard for more than the set time: alarm and shutdown.

[0103] The closed door 41 is not closed signal: the conveyor belt 6 stops running and an alarm is sounded.

[0104] Summarize:

[0105] In this embodiment, the control system coordinates the work of sensors and actuators through the central control module to achieve fully automated operation of the mussel shelling device. The weight sensor ensures the accuracy of mussel separation, the temperature and pressure sensors ensure the efficiency of the refrigeration process, and the position sensor and the electric push rod cooperate to achieve automatic transportation and closed-loop control. The overall system not only improves processing efficiency, but also has abnormal alarm and fault shutdown functions to ensure the safety and reliability of operation.

[0106] Working principle: when it is necessary to shell the mussels, the corresponding mussels should all be poured in from the position of the feed hopper 21, so that the mussels will enter the internal space of the portioning tank 22, and the motor 27 will start normally at this time, thereby driving the rotating column 24 to rotate through the driving shaft 28, and when the rotating column 24 rotates, the partition plate 25 will all rotate with the rotating column 24 as the center of the circle, so as to separate the incoming mussels into portions of similar size. It is worth mentioning that when facing mussels of different sizes, according to the overall size distribution, we can also rotate the turntable 26 to drive the rotating column 24 and the driving shaft 28 to separate, so as to replace the rotating column 24 and the partition plate 25 of the new separation space size. After the mussels are quantitatively separated, they will pass through The discharge pipe 23 transports the mussels to the surface of the conveyor belt 6. At this time, the partition plate 25 arranged on the surface of the conveyor belt 6 will divide the transported mussels into rows. Some of the accumulated mussels can also be dispersed by the belt 58 through the pulley driven by the driving roller 7 that must be driven when the conveyor belt 6 is running, and the stirring rod 56 driven by the synchronously rotating rotating column 2 55 drives the accumulated mussels to be dispersed, so that they will not be piled up together, and then they are smoothly transported by the conveyor belt 6. In addition, in the case of mussels of different sizes, the corresponding driving seat 51 can drive the connecting rod 1 52 to rotate around the driving source of the driving seat 51, so that the connecting rod 2 53 changes synchronously due to the change in the inclination angle of the connecting rod 1 52, so that the pushing rods of the connecting rods 1 52 and the connecting rods 2 53 are Pulling makes the connecting block 54 drive the rotating column 2 55 to adjust the height as a whole, so that mussels of different sizes can be adapted, so that they can be handled more perfectly when their stacking is broken up. After the mussels are arranged, the electric push rod 1 42 can drive the closed door 41 to slide, so that the mussels are transported to the position of the refrigeration mechanism 4 inside the rack 1 through the conveyor belt 6 in batches. At this time, the closed door 41 is closed by the electric push rod 1 42. At this time, the low-temperature and low-pressure refrigerant vapor is sucked into the compressor 43 from the evaporator 46, and becomes high-temperature and high-pressure superheated vapor after compression. The high-temperature and high-pressure refrigerant vapor enters the condenser 44, exchanges heat with the external cooling medium such as air or water, releases heat and condenses into high-pressure liquid. When the high-pressure liquid refrigerant flows through the expansion valve 45, the pressure is rapidly reduced due to the throttling effect, and it becomes a low-temperature and low-pressure liquid and gas mixture. The low-temperature and low-pressure refrigerant enters the evaporator 46, absorbs the heat of the cooled medium, and is completely vaporized into low-pressure steam, and then returns to the compressor 43, so that the refrigeration effect is achieved through continuous circulation. At this time, the mussels are quickly frozen, so that the shells and the flesh are quickly separated. Finally, the frozen mussels will continue to be transported by the conveyor belt 6. At this time, the electric door 9 will open, and then a batch of frozen mussels will be transported to the vibration box 31 and fall on the vibration plate 34. At this time, the motor 2 35 is started, so that the gear 1 36 starts to mobilize the gear 2 37 to rotate in the opposite direction. At this time, the gear 2 37 drives the turntable 2 38 to rotate synchronously.Then the connecting plate 39 is pulled at the eccentric position of the second turntable 38. At this time, both ends of the connecting plate 39 will rotate to a certain extent, thereby ensuring the normal operation of the second turntable 38 and the vibration plate 34. At this time, the mussels on the vibration plate 34 will be vibrated to finally separate the shell and the meat. Finally, due to the inclined design of the vibration plate 34, when the vibration plate 34 is pulled back and forth and vibrated, it will fall into the receiving box 8 at the tilt angle for collection.
