Description

Technical Field

[0001] This utility model relates to the field of fresh shrimp processing equipment, and in particular to a shrimp peeling production line. Background Technology

[0002] China is the world's largest producer and trader of shrimp products. Shrimp meat is rich in protein, and its tender texture makes it easy to digest, making it a delicious ingredient. However, peeling shrimp shells is a hassle every time you eat shrimp, and manually removing the shrimp vein is even more tedious.

[0003] The processing steps of a shrimp peeling machine typically include pretreatment, feeding, peeling, and discharging. Pretreatment involves soaking in ice water and breaking up the shrimp. The pretreated shrimp are then fed to the peeling stage for shell-meat separation. The discharging stage collects and transports the shrimp meat and shells separately. A filtration and water circulation system is also included. However, existing shrimp peeling machines only filter and clean the most valuable shrimp meat after discharging, thus improving its quality. The shrimp shells, however, also have significant value, including in shrimp oil production and cosmetic manufacturing; their quality is equally important. Therefore, a new type of shrimp peeling production line is urgently needed to address these issues. Utility Model Content

Reference Figure 1 and Figure 4 In some embodiments, the shrimp filtration device 400 includes a second frame 410 and a first filter tank 420, a third collection tank 430, a recovery tank 440, and a fourth conveyor belt 450 disposed on the second frame 410. An overflow plate 460 is disposed in the first filter tank 420 to divide it into a first filter chamber 421 and an overflow chamber 422 communicating with the first filter chamber 421. Impurities float on the water surface and enter the overflow chamber 422 through the overflow plate 460, while shrimp sink to the bottom of the first filter chamber 421. The fourth conveyor belt 450 is connected between the first filter tank 420 and the third collection tank 430 for conveying shrimp. The third collection tank 430 is used to collect shrimp. The recovery tank 440 is connected to the overflow chamber 422 for collecting impurities.

[0056] Specifically, the third conveyor belt 310 transports shrimp to the first filter tank 420 (first filter chamber 421). Heavier shrimp sink to the bottom of the first filter chamber 421, while lighter impurities float on the surface. They then pass through the overflow plate 460 into the overflow chamber 422, and finally into the recycling tank 440. Furthermore, a shrimp-peeling production line also includes several first filter screens 470 installed in the recycling tank 440. Impurities are intercepted by the first filter screens 470, while water flows through the first filter screens 470 and is recycled by the recycling tank 440, entering the water circulation system for further circulation. Firstly, two overflow plates 460 are arranged opposite each other to create two overflow chambers 422 on both sides of the first filter chamber 421. By creating two overflow chambers 422, the filtration efficiency and filtration effect can be multiplied. Furthermore, the recovery tank 440 is provided with a side-opening slide groove 441, in which the first filter screen 470 is inserted. This allows for easy replacement of the first filter screen 470, and multiple first filter screens 470 can be stacked sequentially. When replacing and cleaning the upper first filter screen 470, the machine does not need to be stopped, and water containing impurities will not enter the recovery tank 440.

Reference Figure 1 and Figure 4 In some embodiments, at least two first filter tanks 420 and fourth conveyor belts 450 are provided, with the other end of the previous fourth conveyor belt 450 connected to the next first filter tank 420 to form a multi-stage filtration structure; preferably, two first filter tanks 420 and fourth conveyor belts 450 are provided to form a two-stage filtration structure, which can improve the filtration effect of shrimp and avoid heavy impurities from not being filtered out.

[0058] 8. Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the shrimp shell filtering device 500 includes a third frame 510, a drum 520, a second discharge chute 530, and a spray assembly 540. The drum 520 is rotatably mounted on the third frame 510 and has several water passage holes on its side wall, through which shrimp shells and water are transported to the inner side wall of the drum 520. One end of the second discharge chute 530 extends into the drum 520 to receive shrimp shells. The spray assembly 540 is disposed around the drum 520 to spray the drum 520 so that the shrimp shells on the inner side wall of the drum 520 fall onto the second discharge chute 530.

[0059] The shrimp shells and water in the second collection tank 330 are transported to the shrimp shell filter device 500 through the cooperation of pipes and a delivery pump. Specifically, they are transported to the inner wall of the drum 520. The water is discharged through the water passage holes on the drum 520, while the shrimp shells remain on the inner wall of the drum 520 and move to the inner top wall of the drum 520 under the rotation of the drum 520. The spray assembly 540 sprays the shrimp shells through the water passage holes onto the second discharge chute 530, and then discharges them from the second discharge chute 530. Furthermore, a shrimp peeling production line also includes a third frame 51. The shell-beating assembly 600 on the roller 520 is used to beat the roller 520 so that the shrimp shells attached to the inner side wall of the roller 520 fall onto the second discharge chute 530. As a preferred embodiment of the shell-beating assembly 600, the shell-beating assembly 600 includes a rotating shaft 610 and several flexible belts connected to the rotating shaft 610. The shell-beating assembly 600 is located at the upper end of the roller 520 and can beat the shrimp shells that have rotated to the top of the roller 520 so that they fall onto the second discharge chute 530, which is beneficial for discharging and collecting the filtered and cleaned shrimp shells through the second discharge chute 530.

[0060] 9. Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the drum 520 includes a frame 521 and a second filter screen covering the frame 521, with the water passage holes formed by the second filter screen; of course, the drum 520 can also be formed by a metal sheet with micropores; further, the spray assembly 540 is configured as multiple and evenly arranged around the periphery of the drum 520, which can not only improve the filtration and cleaning effect of shrimp shells, but also increase the probability of shrimp shells falling onto the second discharge chute 530, thereby improving the shrimp shell discharge efficiency; further still, the inner sidewall of the drum 520 is provided with a number of circumferentially spaced ribs 900 extending along the length direction of the drum 520, which can block the shrimp shells so that the shrimp shells can smoothly follow the rotation of the drum 520.

[0061] 10. Reference Figure 1 , Figure 5 and Figure 6In some embodiments, a shrimp peeling production line also includes a second filter tank 710 and several third filter screens 720 disposed on a third frame 510. The third filter screens 720 are spaced apart in the second filter tank 710 to separate several second filter chambers 730. Water flowing out of the drum 520 enters the second filter tank 710. This arrangement can perform multi-stage filtration on the water flowing down from the drum 520, which can prevent impurities from entering the water circulation system. Furthermore, it also includes an annular filter cover 800 disposed in the second filter chamber 730 at the end, which can further filter out impurities, making the water entering the water circulation cleaner. It should be noted that the water filtered by the shrimp shell filter device 500 still contains shrimp oil and other substances, which can be extracted by refining.
