Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of these features.

[0023] Refer to the following drawings Figure 1-Figure 2 The shellfish meat and shell separation system according to an embodiment of the present invention includes a multi-stage separation subsystem 1, each stage of the separation subsystem 1 includes a crushing device 2, a screening device 3, a scraper device 4 and a holding device 5;

[0024] The crushing device 2 includes a crushing box 6, a crushing assembly and a first drive mechanism. The crushing box 6 is arranged in water. The crushing box 6 defines a accommodating chamber. The top end of the accommodating chamber is open to define a feed port 7, and the lower end of the accommodating chamber is open to define a discharge port 8. The crushing assembly is arranged in the crushing box 6 to crush shellfish and seafood. The first drive mechanism is connected to the crushing assembly.

[0025] Specifically, the crushing assembly includes two crushing gears 9, which are positioned relative to each other within the accommodating chamber. The crushing gears 9 are rotatably connected to the crushing box, and the first drive mechanism is connected to the crushing gears 9. As a result, when the two crushing gears 9 rotate, shellfish are crushed by the two crushing gears 9 and fall out from the center. It is understood that the distance between the two crushing gears 9 affects the fine crushing results. The farther the two crushing gears 9 are, the larger the crushed particles are, while the closer the two crushing gears 9 are, the smaller the crushed particles are.

[0026] The screening device 3 includes a screen 10 and a second drive mechanism. The screen 10 is placed in the water and below the discharge port 8. The screen 10 is arranged obliquely to the lower right. The second drive mechanism is connected to the screen 10 to drive the screen 10 to move left and right.

[0027] In practical applications, a screen 10 with mesh specifications that meet screening requirements is selected in advance, so that the meat can pass through the screen 10 while the shell remains on the screen 10.

[0028] The scraper device 4 includes a scraper 11 and a third driving mechanism. The scraper 11 is placed in the water and is close to the lower surface of the screen 10. The third driving mechanism is connected to the scraper 11 to drive the scraper 11 to move along the screen 10.

[0029] The holding device 5 includes a holding box 12, a retractable baffle 13, a fourth drive mechanism and a fifth drive mechanism. The holding box 12 and the baffle 13 are both located in the water. The baffle 13 is located below the screen 10 and is arranged obliquely to the upper right. The fourth drive mechanism is connected to the baffle 13 to drive the baffle 13 to retract and retract. The holding box 12 is located at the lower left of the baffle 13. The fifth drive mechanism is connected to the holding box 12 to drive the holding box 12 to move. A water-permeable hole 14 is provided at the bottom of the holding box 12. When the holding box 12 is full, the fifth drive mechanism can drive the holding box 12 to move so that the holding box 12 is moved out of the pool.

[0030] The multiple separation subsystems 1 are connected in sequence. In any two adjacent separation subsystems 1 , the crushing box 6 of the lower separation subsystem 1 is located to the lower right of the screen 10 of the upper separation subsystem 1 .

[0031] The working principle of this system is as follows: before crushing and separating, the main components of this system need to be placed in water first, and then the crushing device 2 in the primary separation subsystem 1 is turned on, and the shellfish products are sent into the crushing device 2 and then crushed. Since the specific gravity of the meat of shellfish products in water is greater than that of the shell, the meat and the shell will automatically separate after being crushed. The meat will first fall from the discharge port 8 onto the screen 10 of the screening device 3 below, and the shell will then fall from the discharge port 8 onto the screen 10 of the screening device 3 below.

[0032] When the second driving mechanism is turned on, the second driving mechanism drives the screen 10 to move left and right for vibration screening, and at the same time the third driving mechanism drives the baffle 13 to extend. In this way, after the shellfish are crushed, the meat will first fall onto the screen 10, then pass through the screen 10 and fall onto the baffle 13, and finally fall into the holding box 12. The shell will then fall onto the screen 10 and remain on the screen 10. Under the resistance of water, the shell will slowly fall along the screen 10.

[0033] For shellfish, there is usually a part of the meat stuck to the shell and difficult to separate. This part of the meat is usually called meat column. Therefore, when the shell falls onto the screen 10, when the screen 10 vibrates, a part of the meat column on the shell will fall into the mesh of the screen 10. Then, when the third drive mechanism is turned on, the scraper 11 moves along the screen 10 to cut off the meat column and separate the meat column from the shell.

[0034] The broken shells and unbroken small shellfish seafood can slowly fall along the screen 10 and flow into the next level separation subsystem 1, and then repeat the crushing and screening process, which will not be repeated.

[0035] In the multi-stage separation subsystem 1, the gap between the crushing gears 9 of the crushing device 2 in the next-stage separation subsystem 1 is smaller than the gap between the crushing gears 9 of the crushing device 2 in the previous-stage separation subsystem 1, and the mesh size of the screen 10 of the screening device 3 in the next-stage separation subsystem 1 is smaller than the mesh size of the screen 10 of the screening device 3 in the previous-stage separation subsystem 1. In this way, through continuous processing at each stage, it is conducive to the realization of fine operations of shellfish from large to small, from coarse crushing to fine crushing, and from coarse separation to fine separation, so that the meat and shells of shellfish of different sizes can be separated thoroughly and cleanly to ensure the integrity of the meat.

[0036] In summary, each subsystem in this system includes two major processing processes, crushing and screening, and these two processing processes are both carried out in water. By utilizing the different specific gravity of the meat and shell of shellfish, the crushed meat and shell will not be mixed together, which is convenient for separation and processing. At the same time, this system does not perform a single crushing and separation process on shellfish, but adopts a multi-stage separation subsystem 1 to perform continuous processing of shellfish at each level. This is conducive to the realization of fine operation of shellfish from large to small, from coarse crushing to fine crushing, and from coarse separation to fine separation, so that the meat and shells of shellfish of different sizes can be separated thoroughly and cleanly to ensure the integrity of the meat.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
