Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a device for removing black skin from fish. Background Technology

[0002] Catfish are a type of scaleless fish. When preparing them, it's essential to thoroughly remove the slippery mucus covering their skin with boiling water. This mucus is not only slimy to the touch, but if not removed completely, it can negatively impact the subsequent cooking and eating experience. However, even after boiling, a layer of black skin often stubbornly remains on the catfish skin. This black skin is extremely persistent, and if any residue remains during cooking, it will cause the fish meat to emit a fishy smell, damaging the overall taste and flavor of the dish.

[0003] In traditional hand-processing methods, experienced chefs often use sharp knives to scrape away the slime and black skin. Some chefs also choose to use steel wool to scrub it clean. However, both scraping and scrubbing are extremely time-consuming and labor-intensive, undoubtedly a heavy manpower burden for restaurants or food processing companies that need to process large quantities of catfish.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0033] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] Example 1:

[0035] Embodiment 1 of this utility model provides a device for removing black skin from fish skin, such as... Figure 1As shown, the device includes: an inner cylinder 1, an outer cylinder 2, a handle 3, a head retainer 4, and a tail retainer 5; the inner cylinder 1 and the outer cylinder 2 are elastically connected, and the head retainer 4 and the tail retainer 5 are rotatably connected to the outer cylinder 2; a skin scraper 10 is provided on the inner surface of the inner cylinder 1, and the inner cylinder 1 is formed by rolling up an elastic plate; specifically, the elastic plate can be a plastic plate or a sheet metal plate, and rolling up the elastic plate allows it to adaptively expand and contract according to the size of the fish body. To further ensure that the inner cylinder 1 fits snugly against the fish body, the inner cylinder 1 includes multiple inner cylinder units 11, each of which is separately arranged; specifically, there may be no gap or a gap of about 1mm between the inner cylinder units 11, so that the fish body is completely enveloped by each inner cylinder unit 11. The inner cylinder unit 11 and the outer cylinder 2 are provided with multiple springs 7. The two ends of the springs 7 are fixedly connected to the inner cylinder unit 11 and the outer cylinder 2, respectively. The springs 7 apply a pushing force to each inner cylinder unit 11. The skin scraper 10 is either a steel wool or Velcro. Considering that fish bodies are mostly flat, Velcro attached to the inner wall of the inner cylinder 1 cannot completely fit the fish body during use. Therefore, in the preferred embodiment, steel wool is densely distributed on the inner wall of the inner cylinder 1. During use, the fish body squeezes the steel wool, allowing the steel wool to better fit the fish body, and the effect of scraping off mucus and black skin is also better. It is worth mentioning that before putting the fish into the inner cylinder 1, the fins need to be cut off to prevent the fins from snagging on the skin scraper 10, which would affect the effect of scraping off mucus and black skin. The head retainer 4 is used to hold the head of the fish, the tail retainer 5 is used to hold the tail of the fish, and the handle 3 is located on the side where the head retainer 4 is located. The handle 3 is fixedly connected to the head retainer 4.

[0036] Compared to existing methods of scraping away mucus and black skin from catfish with a knife or steel wool, the fish skin and black skin removal device provided by this invention allows for the removal of the fish's fins, placement of the fish in the inner cylinder 1, fixation of the fish's head with a head retainer 4, and fixation of the fish's tail with a tail retainer 5. By rotating the handle 3, the fish rotates within the inner cylinder 1, and the mucus and black skin on the fish are scraped off by the skin scraper 10 installed in the inner cylinder 1. Compared to manual scraping with a knife or steel wool, this device is more efficient and produces better results in removing mucus and black skin, especially when processing large quantities of catfish.

[0037] To fully illustrate the solutions provided by the embodiments of this utility model, the structures provided by the above solutions will be described in further detail below.

[0038] To facilitate the installation of the head restraint 4 and the tail restraint 5, such as Figure 2As shown, the outer cylinder 2 is provided with a top cover 20 and a tail cover 21. The head retainer 4 is rotatably connected to the top cover 20, and the tail retainer 5 is rotatably connected to the tail cover 21. The top cover 20 and tail cover 21 are detachably connected to the outer cylinder 2. In practical application, the tail cover 21 is first removed, the tail retainer 5 is used to secure the fish tail, and the fish is placed into the inner cylinder 1 from the head position. After the fish head protrudes from the inner cylinder 1, the head retainer 4 is used to secure the fish head, and the top cover 20 and tail cover 21 are then fastened and secured to the outer cylinder 2, completing the placement of the fish body. Specifically, the head retainer 4 includes a first mounting block 40. To ensure smooth rotation between the first mounting block 40 and the top cover 20, the first mounting block 40 and the top cover 20 are rotatably connected via a bearing or ball bearing. The handle 3 is fixedly connected to the outer side of the first mounting block 40. The tail retainer 5 includes a second mounting block 50. In order to ensure that the second mounting block 50 and the tail cover 21 can rotate smoothly, the second mounting block 50 and the tail cover 21 are rotatably connected by a bearing or a ball bearing.

[0039] To securely hold the fish head and tail in place and prevent them from falling off during rotation, such as Figure 2 and Figure 3 As shown, both the head retainer 4 and the tail retainer 5 include a clip 51. The clip 51 of the head retainer 4 is connected to the first mounting block 40, and the clip 51 of the tail retainer 5 is connected to the second mounting block 50. The clip 51 of the tail retainer 5 is used to hold the fish tail, and the clip 51 of the head retainer 4 is used to hold the fish head. The clamping part of the clip 51 is serrated.

[0040] Because fish vary in size, to accommodate different fish shapes, one of the clamping units of the clamp 51 has a sliding groove 510 on its side, such as... Figure 4 As shown, the first mounting block 40 has a first through hole 400 at its center, and the second mounting block 50 has a second through hole 500 at its center. The sidewalls of the first and second through holes 400 and 500 are respectively provided with guide protrusions 401, which are slidably connected to the slide groove 510. In actual processing, the clamp 51 is made of stainless steel. To ensure reliable connection between the handle 2 and the head retainer 4, the handle 3 is fixedly connected to the first mounting block 40, or the handle 3 is integrally formed with the first mounting block 40, to prevent breakage at the connection between the handle 3 and the clamping unit during use. To prevent the handle 3 from obstructing the opening and closing of the clamp 51, the connection between the handle 3 and the first mounting block 40 is semi-circular, meaning the connection occupies at most half the annular area of ​​the first mounting block 40.

[0041] During use, in order to facilitate observation of the fish's condition, the outer cylinder 2 is made of transparent material. When using the skinner 10 to scrape the fish's body, the mucus on the fish's body is scraped off. In order to prevent the mucus from flowing out and accumulating inside the device, the outer cylinder 2 is provided with multiple leakage holes 6, which are used to allow the scraped mucus to flow out.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
