Description

Technical Field

[0001] This invention relates to the field of scallop processing technology, and in particular to a shell-cutting and scraping method for primary processing of scallops. Background Technology

[0002] Scallops, as an important representative of marine biological resources, possess multi-dimensional value and represent a crucial pathway for the synergistic advancement of marine ecological protection, food security, and bioeconomic innovation. Current scallop primary processing often employs rough vibration to detach the adductor muscle from the shell. However, during scallop handling and processing, cooking and subsequent manual sorting are frequently required to ensure all scallops are removed from their shells. Since cooked seafood loses much of its freshness and broken scallop shells possess a certain sharpness, traditional scallop processing methods are clearly inadequate, considering both worker safety during harvesting and the increasing demands of consumers for higher quality food. Therefore, the design and development of a novel scallop primary processing machine is of great significance for promoting food safety and building a diversified food supply system.

[0003] However, extracting scallop meat from live scallops presents several challenges. The primary objective is to open the tightly closed shell without damaging the meat, separating the adductor muscle from the shell wall and removing it intact. Because the adductor muscle of a live scallop exerts a much stronger suction on the shell than that of a cooked scallop, the force applied to the knife during the extraction process is crucial. Excessive force, however, can damage the scallop meat. Therefore, the method of opening the scallop shell and the precise control of the force applied to separate the adductor muscle during extraction require careful consideration to ensure the stability, reliability, and safety of the designed device.

[0004] Research on primary processing machinery for live scallops in China is still in its early stages, but preliminary results have been achieved. Domestic approaches to solving the scallop opening problem focus on two aspects. Firstly, utilizing the physiological characteristics of scallops, research explores the influence of chemical and physical factors on scallop opening. Regarding physical factors, institutions such as Ocean University of China and Dalian Ocean University utilize the stress response of live scallops. For example, under specific temperature, salinity, or electrical stimulation, scallops will slightly open for a period, allowing for opening. Secondly, regarding chemical factors, domestic research institutions induce scallops into a dormant state under low temperature and specific anesthetic conditions before opening. Both methods obviously increase processing costs, raising production costs. Furthermore, the effects of overly harsh physical and chemical methods on the texture and taste of scallop meat have not yet been demonstrated, clearly not in line with modern processing methods. Another major challenge is how to achieve non-destructive separation of the shell muscle from the shell.

[0005] Currently, existing scallop meat extraction devices typically pre-cook the scallops to reduce the adhesion of the shell muscles to the shell wall. However, this method leads to a loss of scallop flavor, and cooked scallop meat, if not frozen within two hours, can develop Salmonella, posing a food safety issue. The live extraction method not only perfectly solves these problems but also saves production and labor costs in the cooking process, thus promoting the further development of scallops. It can also explore solutions for opening shells of other similar shellfish. Regarding meat extraction, traditional methods typically require manual labor to remove the meat intact without damaging it. However, manual operation is prone to fatigue, and varying skill levels limit scallop yield to some extent. This application explores a novel meat extraction method that extracts meat without damaging it. It can also provide a meat extraction method for similar shellfish such as razor clams or cat's eye snails. Therefore, the live scallop primary processing device has significant potential for widespread application.

[0006] In summary, designing a live scallop primary processing device that is highly efficient, simple in structure, inexpensive, and highly automated is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a shell-cutting and scraping scallop meat extraction device and method.

[0020] This invention also provides a method for the initial processing of scallops by shell cutting and scraping, which is implemented using the aforementioned scallop initial processing device. The method includes the following steps:

[0021] Step S1, scallop loading: First, place the scallops on the scallop loading platform, with their tails in the grooves. Continue to place the scallops in the same position on the platform. Figure 8 As shown;

[0022] Step S2, Scallop Fixing: Then, the first motor drives the first ball screw mechanism to transport the low-pressure clamping and conveying mechanism to the scallop loading platform. The second motor drives the second ball screw mechanism to bring the movable side suction cup close to the scallop. Subsequently, the solenoid valve is opened, and the vacuum machine starts working. The vacuum suction cup is pressed tightly against the scallop shell, creating a pressure difference that allows the scallop to be held in place by the rubber pad. The vacuum suction cup then carries the scallop to the next working area, such as... Figure 9 As shown;

[0023] Step S3, Scallop Shell Cutting: When the first motor drives the first ball screw mechanism to transport the low-pressure gripping conveyor to the tungsten carbide alloy cutting device, the tungsten carbide alloy cutting device will cut off the tail fin of the scallop as the low-pressure gripping conveyor moves, creating a cut below the scallop to facilitate the execution of subsequent mechanisms, such as... Figure 10 As shown;

[0024] Step S4, Separation of the two shells: The first motor continues to drive the first ball screw mechanism to transport the low-pressure gripping and conveying mechanism to the wedge-shaped blade opening mechanism. The fourth motor drives the third ball screw module 42 to make the wedge-shaped blade move up and down. When the wedge-shaped blade enters the scallop, the scallop shell slowly opens as the wedge-shaped blade enters. At the same time, the second motor and the second ball screw mechanism rotate in the opposite direction. Under the combined force of the blade and the suction nozzle, the upper and lower scallop shells open, the adductor muscle separates from one side of the shell, and the two shells continue to enter the next working area on the low-pressure gripping and conveying mechanism, such as... Figure 11 As shown;

[0025] Step S5, Scallop Cleaning: The first motor continues to drive the first ball screw mechanism to transport the low-pressure clamping and conveying mechanism to the bottom of the rinsing device. Then, the water pump operates to perform preliminary cleaning of the scallop adductor muscles. The scallops are then carried to the next workstation. Figure 12 As shown;

[0026] Step S6, Scallop Adductor Scraping: The scallops are brought into the adductor cutting and collection area. The fifth motor drives a miniature rotating contoured elastic blade to scrape the adductor. The scraped adductor falls into a stainless steel collection frame, completing the scraping and collection of the adductor. Figure 13 As shown;

[0027] Step S7: Subsequently, the first motor drives the first ball screw mechanism to rotate in the opposite direction, and closes the vacuum pump and solenoid valve in front, causing the scallop shell to fall off; the low-pressure clamping and conveying mechanism returns to the top of the scallop feeding machine mechanism, thus completing one work cycle.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

8. A method for primary processing of scallops by shell cutting and scraping, wherein the method is implemented using a scallop primary processing device for shell cutting and scraping as described in any one of claims 1-7, characterized in that, The method includes the following steps: Step S1, scallop loading: First, place the scallops on the scallop loading platform, with the tail fins of the scallops placed in the grooves of the scallop loading platform. The subsequent scallops will also maintain the same posture on the scallop loading platform. Step S2, scallop fixing: Then, the first motor (14) drives the first ball screw mechanism (9) to transport the low-pressure clamping and conveying mechanism to the scallop loading platform. The second motor (16) drives the second ball screw mechanism (10) to bring the movable side suction cup close to the scallop. Then the solenoid valve is opened and the vacuum machine starts to work. The vacuum suction cup is close to the scallop shell, and a pressure difference is created. The scallop is sucked by the vacuum suction cup and the rubber pad is used to fix the scallop. Then the vacuum suction cup carries the scallop to the next working area. Step S3, Scallop shell cutting: When the first motor (14) drives the first ball screw mechanism (9) to transport the low-pressure gripping conveyor to the tungsten carbide alloy cutting device, the tungsten carbide alloy cutting device cuts off the tail fin of the scallop as the low-pressure gripping conveyor moves, so that a cut appears under the scallop, which facilitates the execution of subsequent mechanisms. Step S4, Separation of the two shells: The first motor (14) continues to drive the first ball screw mechanism (9) to transport the low-pressure gripping conveyor to the wedge blade opening mechanism. The fourth motor (47) of the wedge blade drives the third ball screw module (42) to make the wedge blade move up and down. When the wedge blade enters the scallop, the scallop shell slowly opens as the wedge blade enters. At the same time, the second motor (16) drives the second ball screw mechanism (10) to rotate in the opposite direction. Under the dual force of the blade and the suction nozzle, the upper and lower scallop shells open, the adductor and one side shell separate, and the two shells continue to enter the next working area on the low-pressure gripping conveyor. Step S5, Scallop cleaning: The first motor (14) continues to drive the first ball screw mechanism (9) to transport the low-pressure clamping and conveying mechanism to the bottom of the rinsing device. Then the water pump works to perform preliminary cleaning of the adductor muscle. Then the scallops are carried to the next station. Step S6, Scraping of the adductor muscle: The scallop is brought into the adductor muscle cutting and collection work area. The fifth motor (54) drives the micro rotating contour elastic blade (55) to scrape the adductor muscle. The adductor muscle is scraped off and falls into the stainless steel collection frame, completing the scraping and collection of the adductor muscle. Step S7: Then the first motor (14) drives the first ball screw mechanism (9) to rotate in the opposite direction and closes the vacuum pump and solenoid valve in front, causing the scallop shell to fall off; the low-pressure clamping and conveying mechanism returns to the top of the scallop feeding machine mechanism, thus completing one work cycle.
