Description

Technical Field

[0001] This invention relates to the field of fish-killing equipment technology, and particularly to a fish-killing machine. Background Technology

[0002] Traditionally, fish cleaning is done manually, which is inefficient and labor-intensive, significantly impacting processing efficiency. The introduction of automated fish-cleaning machines has dramatically improved this situation. These machines integrate mechanical, electronic, and automation technologies, aiming to automate the entire process from fish capture to initial processing, greatly reducing manual labor and promoting the modernization of the industry chain. With the rapid development of modern fisheries and food processing industries, the demand for efficient and automated fish-cleaning equipment is increasingly urgent.

[0003] The invention patent with publication number CN104186630A discloses "a fish-killing machine", which mainly includes a descaling mechanism, a traction mechanism, a fish-cleaning mechanism, and a gutting mechanism. In this patent, a water jet sprayed from a high-pressure nozzle is used to wash away the scales on the sides and back of the fish. The impact force of the high-pressure water is not easy to control. When the impact force of the high-pressure water jet is too large, it can easily damage the surface of the fish meat, affecting the appearance quality of the fish and the quality of subsequent processing. When the impact force of the high-pressure water jet is too small, it cannot completely remove the scales, and the descaling effect is not ideal.

[0004] Patent document CN206760618U discloses a "novel fish descaling mechanism," in which descaling blades are fixed to two opposing descaling shafts. Through the relative rotation of the two shafts, the rotating descaling blades on both sides act on the fish scales passing between the blades, and the scales are removed by the serrations on the blades. While this descaling mechanism improves descaling efficiency to some extent, the scales still adhere to the fish's surface or remain on the equipment after being scraped off, making them difficult to clean and affecting the hygiene of subsequent processing. Summary of the Invention

[0005] The purpose of this invention is to provide a fish-killing machine that can not only effectively solve the problems of incomplete descaling and fish damage in the prior art, but also automatically collect and clean the fish scales in the fish body and the machine body during the fish-killing process, avoiding the impact of fish scale residue on equipment cleaning and subsequent processing, and greatly improving the processing efficiency and hygiene standards of the equipment.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A fish-killing machine includes a body. A fish-infeeding mechanism is located at the top of the body. Below the fish-infeeding mechanism are sequentially arranged a descaling mechanism, a cutting mechanism, and a fish-outfeeding mechanism. The descaling mechanism includes a two-sided descaling mechanism and a dorsal descaling mechanism for descaling the sides and back of the fish, respectively. Below both the two-sided and dorsal descaling mechanisms is a fish scale collecting mechanism. The fish scale collecting mechanism includes two parallel, opposite, and rotating fish scale collecting rollers and a fish scale collecting groove located below the fish scale collecting rollers. Multiple movable scrapers are arranged on the fish scale collecting rollers. Each movable scraper is slidably engaged with a radial groove on the fish scale collecting roller. A return spring is located at the bottom of the radial groove. One end of the return spring is fixedly connected to the bottom of the radial groove, and the other end is fixedly connected to the movable scraper.

[0008] By adopting the above technical solution, the fish to be processed is fed in by the fish feeding mechanism and then passes through the two-sided descaling mechanism and the belly and back descaling mechanism in sequence for descaling. The two-sided descaling mechanism and the belly and back descaling mechanism work together to achieve multi-directional descaling of the fish body, making the descaling more thorough. While scraping off the scales on the sides and belly and back of the fish body respectively, the two-sided descaling mechanism and the belly and back descaling mechanism collect the scraped scales in real time through the fish scale collection mechanism to avoid fish scale residue affecting equipment cleaning and subsequent processing. The fish scale collection mechanism uses the relative rotation of the fish scale collection roller to drive the movable scraper to rotate along the growth direction of the fish scales. On the one hand, it can effectively peel off the fish scales adhering to the surface of the fish body and scrape them into the fish scale collection trough. On the other hand, it can also apply a force opposite to the descaling direction to the fish body, effectively reducing the descent speed of the fish during the descaling process. This effectively avoids the problem of incomplete descaling caused by the fish body falling too fast, further ensuring that the fish scales can be fully removed and enhancing the descaling effect.

[0009] In addition, the sliding cooperation between the movable scraper and the fish scale collecting roller in the fish scale collecting mechanism, as well as the function of the return spring, enable the movable scraper to adapt to the shape of fish of different sizes and always keep in close contact with the surface of the fish. This not only effectively improves the fish scale collection effect, but also effectively ensures that the movable scraper has a certain buffering effect when it comes into contact with the fish, avoiding scratching the fish meat, thereby better protecting the integrity and appearance quality of the fish meat.

[0010] A further configuration of the present invention is as follows: both the descaling mechanisms on both sides and the descaling mechanism on the belly and back include two descaling rollers arranged in parallel and opposite to each other and rotating against the direction of fish scale growth. Each descaling roller is provided with multiple movable descaling plates. Each movable descaling plate is slidably engaged with a radial groove on the descaling roller. A return spring is provided at the bottom of the radial groove. One end of the return spring is fixedly connected to the bottom of the radial groove, and the other end of the return spring is fixedly connected to the movable descaling plate. The axes of the descaling rollers in the descaling mechanisms on both sides and the descaling mechanism on the belly and back are perpendicular to each other.

[0011] By adopting the above technical solution, the descaling rollers in the descaling mechanisms on both sides and the belly and back are set perpendicular to each other, enabling them to perform multi-angle descaling of the fish body along both sides and the belly and back sides perpendicular to both sides of the fish body. This effectively enhances the comprehensiveness and effectiveness of the descaling operation. The movable descaling plate achieves elastic extension and retraction through the second return spring, allowing it to automatically adapt to the outline of fish bodies of different sizes and shapes. During the descaling process, it can always closely fit the surface of the fish body, effectively preventing descaling blind spots caused by differences in the shape and size of the fish body. This improves the applicability and descaling efficiency of the equipment, while avoiding unnecessary damage to the fish meat and ensuring the integrity and appearance quality of the fish body.

[0012] During the descaling process, the relative rotation direction of the two scale collecting rollers in the descaling mechanisms on both sides and the belly and back is opposite to the natural growth direction of the fish scales. This allows the end of the movable descaling plate to be inserted into the gaps between the fish scales, prying the scales out of the gaps and peeling them off. This not only enhances the peeling effect of the fish scales, but also protects the surface of the fish meat, preventing damage to the fish meat and ensuring the appearance quality and processing quality of the fish.

[0013] A further configuration of the present invention is that the circumferences of the movable scrapers on the two fish scale collecting rollers in the fish scale collecting mechanism that are away from the center of the fish scale collecting rollers are tangent to each other, and the circumferences of the movable descaling plates on the two descaling rollers in the two descaling mechanisms on both sides and the belly and back descaling mechanism that are away from the center of the descaling rollers are tangent to each other.

[0014] By adopting the above technical solution, the circumferences of the movable scrapers on the two fish scale collecting rollers in the fish scale collecting mechanism and the circumferences of the ends of the movable descaling plates on the two descaling rollers in the two side descaling mechanisms and the belly and back descaling mechanism are all tangent, so that fish of all sizes can fully contact the ends of the movable scrapers or movable descaling plates when they pass by and form a squeezing state between the ends of the movable scrapers or movable descaling plates, thereby ensuring that the fish scales can be effectively peeled off or collected.

[0015] A further configuration of the present invention is as follows: the two descaling rollers in the two-sided descaling mechanism and the two fish scale collecting rollers in the fish scale collecting mechanism below them, as well as the two descaling rollers in the belly and back descaling mechanism and the two fish scale collecting rollers in the fish scale collecting mechanism below them, are all connected to a descaling drive mechanism. The descaling drive mechanism includes a descaling drive motor fixed on the machine body, and its telescopic shaft is connected to one of the descaling rollers in the two-sided descaling mechanism or the belly and back descaling mechanism. A descaling drive gear is fixedly provided at the other end of the descaling roller in the two-sided descaling mechanism or the belly and back descaling mechanism connected to the descaling drive motor. A descaling driven gear that meshes with the descaling drive gear is provided on the descaling roller adjacent to the descaling roller connected to the descaling drive motor. The descaling roller where the descaling drive gear is located is connected to the fish scale collecting roller that is not adjacent to it by a timing belt one. The descaling roller where the descaling driven gear is located is connected to the fish scale collecting roller that is not adjacent to it by a timing belt two.

[0016] By adopting the above technical solution, two descaling drive mechanisms are used to drive the descaling mechanisms on both sides and the descaling mechanism on the belly and back, as well as the fish scale collection mechanism below them, to operate synchronously. This ensures that each mechanism maintains a stable rhythm during operation, thereby improving descaling efficiency and consistency. After the descaling drive motor starts, it drives the descaling roller connected to it to rotate, which in turn causes the descaling drive gear to rotate. When the descaling drive gear rotates, it drives the descaling driven gear to rotate synchronously. When the descaling driven gear rotates, it drives the descaling roller connected to it to rotate. The two descaling rollers drive the corresponding fish scale collection rollers to operate synchronously through synchronous belt one and synchronous belt two, respectively. This allows the two descaling rollers to rotate relative to each other against the growth direction of the fish scales, while the two fish scale collection rollers rotate relative to each other synchronously along the growth direction of the fish scales. This achieves efficient removal and synchronous collection of fish scales during the descaling process, avoiding fish scale residue and reducing damage to the surface of the fish. This further ensures the appearance quality and processing quality of the fish, effectively improving the overall automation level and working efficiency of the equipment.

[0017] A further configuration of the present invention is as follows: the bottom of the fish scale collecting trough is inclined, the higher side of the bottom of the fish scale collecting trough is located below the fish scale collecting roller, the lower side of the bottom of the fish scale collecting trough is connected to the fish scale discharge pipe, the bottom of the fish scale discharge pipe is connected to the fish scale collecting box at the bottom of the machine body, the bottom of the fish scale collecting box is an inclined surface, and the lower side of the bottom of the fish scale collecting box is connected to the fish scale discharge outlet on the side wall of the machine body.

[0018] By adopting the above technical solution, the bottom of the fish scale collection tank is inclined, which allows the fish scales to slide smoothly into the fish scale discharge pipe and into the fish scale collection box at the bottom of the machine under the action of gravity, effectively avoiding the accumulation and blockage of fish scales and improving the fish scale collection efficiency. The inclined surface design at the bottom of the fish scale collection box allows the fish scales to fall to the lower side of the bottom after entering the fish scale collection box and be discharged from the fish scale discharge port on the side wall of the machine, which facilitates the subsequent cleaning and recycling of fish scales, thereby improving the overall working efficiency and hygiene level of the equipment.

[0019] A further configuration of the present invention is as follows: the fish feeding mechanism includes a fish feeding hopper, the fish feeding hopper includes two openable fish guide plates, the opposite sides of the fish guide plates are V-shaped guide surfaces with opposite openings, the V-shaped guide surfaces on the two fish guide plates form a feeding port, the feeding port has a conical structure with a large opening at the top and a small opening at the bottom, the two fish guide plates are respectively slidably engaged with a sliding rod through a sliding seat, the two ends of the sliding rod are respectively connected to the side wall of the machine body, a compression spring is sleeved on the sliding rod, the compression spring is located between the sliding seat and the side wall of the machine body and its two ends are respectively connected to the sliding seat and the side wall of the machine body.

[0020] By adopting the above technical solution, the openable fish guide plate can automatically adjust the size of the feed inlet according to the size of the fish during the feeding process, allowing fish of different sizes to enter the equipment smoothly, avoiding jamming or damage to the fish, while ensuring the continuity and stability of the subsequent descaling process and improving overall work efficiency. The two fish guide plates form a feed opening through the opposing V-shaped guide surfaces, which can effectively guide the fish to enter. The V-shaped structure of the guide surfaces can adapt well to fish of different shapes and sizes. Moreover, the feed opening formed by the V-shaped guide surfaces on the two fish guide plates has a conical structure with a large opening at the top and a small opening at the bottom, making it easy for the fish to enter the feed opening. Since the fish guide plates can maintain an appropriate clamping force under the action of the compression spring, the fish can be stably clamped by the smaller opening at the bottom of the feed opening after entering, thereby preventing the fish from falling out or deviating due to swinging during the feeding process, greatly improving the stability of feeding and the safety of equipment operation.

[0021] A further configuration of the present invention is as follows: the slitting mechanism includes a slitting blade, the rotation center of the slitting blade is connected to the output shaft of a rotary drive motor, the rotary drive motor is fixed on a motor bracket, the motor bracket is fixed on a sliding seat, the sliding seat is slidably engaged with a slide rail fixed on the machine body, the sliding seat is threadedly connected to an adjusting screw inside the slide rail, and one end of the adjusting screw extends out of the machine body and is connected to an adjusting handwheel.

[0022] By adopting the above technical solution, the cutting mechanism is used to precisely cut the fish. During cutting, the cutting disc rotates at high speed under the drive of the motor. The cutting disc automatically cuts the fish in the high-speed rotation state, which facilitates further processing of the fish in subsequent processes. When cutting fish of different sizes or different species, the position of the sliding seat on the slide rail can be adjusted by adjusting the screw, thereby precisely controlling the contact depth between the cutting disc and the fish, avoiding the problem of fish damage or incomplete cutting due to improper cutting depth.

[0023] A further feature of the present invention is that the fish dispensing mechanism includes a fish dispensing guide groove, which is fixed at the upper opening of the fish scale collection box. The bottom of the fish dispensing guide groove is inclined and has a hollow structure. The inclination direction of the fish dispensing guide groove is opposite to the inclination direction of the fish scale collection groove. The lower end of the fish dispensing guide groove is connected to the fish outlet on the side wall of the machine body.

[0024] By adopting the above technical solution, the fish discharge guide channel is used to smoothly export the fish body after it has been gutted. Its perforated structure effectively separates residual fish scales and impurities, ensuring the cleanliness of the fish and improving the quality of subsequent processing. The inclination direction of the fish discharge guide channel is opposite to that of the fish scale collection channel, making the direction of fish body export opposite to the direction of fish scale discharge. This facilitates the separate collection and processing of fish body and fish scales, not only simplifying operation but also avoiding cross-contamination during operation, greatly improving overall processing efficiency and hygiene standards.

[0025] A further feature of the present invention is that it also includes a slitting conveying mechanism, which includes annular conveying toothed chains symmetrically arranged on both sides of the slitting cutter disc. The annular conveying toothed chains are driven and supported by a drive sprocket and a driven sprocket, respectively. The drive sprocket is connected to the output shaft of a conveying drive motor fixed on the machine body. On the side of the two annular conveying toothed chains that are close to each other, a plurality of tensioning wheels are provided, and each tensioning wheel is connected to the machine body through a tension adjustment mechanism.

[0026] By adopting the above technical solution, the cutting and conveying mechanism uses two ring-shaped conveying tooth chains to stably support and transport the fish during the cutting process, ensuring that the fish is evenly stressed and passes smoothly through the cutting disc, avoiding the fish from falling quickly and failing to be cut evenly. At the same time, the tension wheel can ensure that the ring-shaped conveying tooth chains are always kept taut, thereby ensuring the stability and reliability of the conveying process.

[0027] A further embodiment of the present invention is that the tension adjustment mechanism includes an adjustment slider rotatably connected to the tension wheel, the adjustment slider is slidably engaged with a groove on a support plate fixedly disposed inside the machine body, the adjustment slider is also slidably engaged with a guide rod fixed on the support plate, one end of the guide rod is fixed to the support plate by a mounting seat, and the other end of the guide rod is fitted with a tension spring, the two ends of the tension spring being connected to the adjustment slider and the mounting seat respectively.

[0028] By adopting the above technical solution, the tension adjustment mechanism can adjust the position of the tension wheel in real time, which can not only adapt to fish of different thicknesses, thus keeping the annular conveyor chain in the best conveying state during operation, but also, under the elastic action of the tension spring, the tension wheel can slide along the guide rod with the adjusting slider, thereby automatically compensating for the loosening phenomenon of the annular conveyor chain due to long-term use, further improving the stability and durability of the conveying system.

[0029] The beneficial effects of this invention are:

[0030] 1. After the fish to be processed is fed in by the fish feeding mechanism, it passes through the descaling mechanisms on both sides and the belly and back in sequence for descaling. The descaling mechanisms on both sides and the belly and back work together to achieve multi-directional descaling of the fish, making the descaling more thorough. While scraping off the scales on the sides and belly and back of the fish respectively, the descaling mechanisms on both sides and the belly and back collect the scraped scales in real time through the fish scale collection mechanism to avoid fish scale residue affecting equipment cleaning and subsequent processing. The fish scale collection mechanism uses the relative rotation of the fish scale collection roller to drive the movable scraper to rotate along the growth direction of the fish scales. On the one hand, it can effectively peel off the fish scales adhering to the surface of the fish and scrape them into the fish scale collection tank. On the other hand, it can also apply a force to the fish body in the opposite direction of descaling, effectively reducing the descent speed of the fish during the descaling process. This effectively avoids the problem of incomplete descaling caused by the fish falling too fast, further ensuring that the fish scales can be fully removed and enhancing the descaling effect.

[0031] 2. In this invention, the sliding cooperation between the movable scraper and the fish scale collecting roller in the fish scale collecting mechanism, as well as the function of the return spring, enable the movable scraper to adapt to the shape of fish of different sizes and always keep in close contact with the surface of the fish. This not only effectively improves the fish scale collection effect, but also effectively ensures that the movable scraper has a certain buffering effect when it comes into contact with the fish, avoiding scratching the fish meat, thereby better protecting the integrity and appearance quality of the fish meat.

[0032] 3. In this invention, the descaling rollers in the descaling mechanisms on both sides and the descaling mechanism on the belly and back are arranged perpendicularly to each other, enabling them to perform multi-angle descaling of the fish along both sides of the fish body and on both sides of the belly and back perpendicular to the sides of the fish body. This effectively enhances the comprehensiveness and effectiveness of the descaling operation. The movable descaling plate achieves elastic extension and retraction through the second return spring, allowing it to automatically adapt to the outline of fish of different sizes and shapes. During the descaling process, it can always closely fit the surface of the fish body, effectively preventing descaling blind spots caused by differences in the shape and size of the fish body. This improves the applicability and descaling efficiency of the equipment, while avoiding unnecessary damage to the fish meat and ensuring the integrity and appearance quality of the fish.

[0033] 4. In the descaling process of this invention, the relative rotation direction of the two scale collecting rollers in the descaling mechanisms on both sides and the belly and back is opposite to the natural growth direction of the fish scales. This allows the end of the movable descaling plate to be inserted into the gaps of the fish scales against the direction of their growth, and to pry the fish scales out of the gaps and peel them off. This not only enhances the peeling effect of the fish scales, but also protects the surface of the fish meat, prevents damage to the fish meat, and ensures the appearance quality and processing quality of the fish.

[0034] 5. The openable fish guide plates in this invention can automatically adjust the size of the feed inlet according to the size of the fish during the feeding process, allowing fish of different sizes to enter the equipment smoothly, avoiding jamming or damage to the fish, while ensuring the continuity and stability of the subsequent descaling process and improving overall work efficiency. The two fish guide plates form a feed opening through the opposing V-shaped guide surfaces, which can effectively guide the fish into the equipment. The V-shaped structure of the guide surfaces can adapt well to fish of different shapes and sizes. Moreover, the feed opening formed by the V-shaped guide surfaces on the two fish guide plates has a conical structure with a large opening at the top and a small opening at the bottom, making it easy for the fish to enter the feed opening. Since the fish guide plates can maintain an appropriate clamping force under the action of the compression spring, the fish can be stably clamped by the smaller opening at the bottom of the feed opening after entering, thereby preventing the fish from falling out or deviating due to swinging during the feeding process, greatly improving the stability of feeding and the safety of equipment operation.

[0035] 6. In this invention, the cutting mechanism is used to precisely cut the fish. During cutting, the cutting disc rotates at high speed under the drive of the motor. The cutting disc automatically cuts the fish when rotating at high speed, which facilitates further processing of the fish in subsequent processes. When cutting fish of different sizes or species, the position of the sliding seat on the slide rail can be adjusted by adjusting the screw, thereby precisely controlling the contact depth between the cutting disc and the fish, avoiding the problem of fish damage or incomplete cutting due to improper cutting depth.

[0036] 7. In this invention, the fish guide channel is used to smoothly discharge the fish after it has been cut. Its perforated structure effectively separates residual fish scales and impurities, ensuring the fish is clean and improving the quality of subsequent processing. The inclination direction of the fish guide channel is opposite to that of the fish scale collection channel, making the direction of fish discharge opposite to the direction of fish scale removal. This facilitates the separate collection and processing of fish and fish scales, not only simplifying operation but also preventing cross-contamination during operation, greatly improving overall processing efficiency and hygiene standards.

[0037] 8. In this invention, the cutting and conveying mechanism uses two annular conveying tooth chains to stably support and transport the fish during the cutting process, ensuring that the fish is evenly stressed and passes smoothly through the cutting disc, avoiding the fish from falling quickly and failing to be cut evenly. At the same time, the tensioning wheel can ensure that the annular conveying tooth chains are always kept taut, thereby ensuring the stability and reliability of the conveying process.

[0038] 9. The tension adjustment mechanism in this invention can adjust the position of the tension wheel in real time, which can not only adapt to fish of different thicknesses, thus keeping the annular conveyor chain in the best conveying state during operation, but also, under the elastic action of the tension spring, the tension wheel can slide along the guide rod with the adjustment slider, thereby automatically compensating for the loosening phenomenon of the annular conveyor chain due to long-term use, and further improving the stability and durability of the conveying system.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1-7 As shown, a fish-killing machine includes a body 1. A fish-inlet mechanism 2 is located at the top of the body 1. Below the fish-inlet mechanism 2, a descaling mechanism 3, a cutting mechanism 4, and a fish-outlet mechanism 5 are arranged sequentially. The descaling mechanism 3 includes a two-sided descaling mechanism 31 and a two-sided descaling mechanism 32, respectively used for descaling the sides and back of the fish.

[0051] Furthermore, the circumferences of the movable scrapers 333 on the two fish scale collecting rollers 331 in the fish scale collecting mechanism 33 are tangent to the circumferences of the ends of the movable scrapers 333 on the two scrapers 311 in the two sides scraper mechanisms 31 and the belly and back scraper mechanism 32, and the circumferences of the movable scrapers 312 on the two scrapers 311 are tangent to the circumferences of the ends of the scrapers 311 on the two sides scraper mechanisms 31 and the belly and back scraper mechanism 32.

[0052] Furthermore, the two descaling rollers 311 in the two side descaling mechanisms 31 and the two fish scale collecting rollers 331 in the fish scale collecting mechanism 33 below them, as well as the two descaling rollers 311 in the belly and back descaling mechanism 32 and the two fish scale collecting rollers 331 in the fish scale collecting mechanism 33 below them, are all connected to the descaling drive mechanism 34. The descaling drive mechanism 34 includes a descaling drive motor 341 fixed on the machine body 1, whose telescopic shaft is connected to one of the descaling rollers 311 in the two side descaling mechanisms 31 or the belly and back descaling mechanism 32.

[0059] The working principle of this invention is as follows: After the fish to be processed is fed in by the fish inlet mechanism 2, it passes through the two side descaling mechanisms 31 and the belly and back descaling mechanism 32 in sequence for descaling. The two side descaling mechanisms 31 and the belly and back descaling mechanism 32 work together to achieve multi-directional descaling of the fish body, making the descaling more thorough. While the two side descaling mechanisms 31 and the belly and back descaling mechanism 32 scrape off the scales on the sides and belly and back of the fish body respectively, the two side descaling mechanisms 31 and the belly and back descaling mechanism 32 collect the scraped scales in real time through the fish scale collection mechanism 33 to avoid fish scale residue. The fish scale collection mechanism 33 uses the relative rotation of the fish scale collection roller 331 to drive the movable scraper 333 to rotate along the growth direction of the fish scales. On the one hand, it can effectively peel off the fish scales adhering to the surface of the fish and scrape them into the fish scale collection groove 332. On the other hand, it can also apply a force to the fish body in the opposite direction of descaling, effectively reducing the falling speed of the fish during the descaling process. This effectively avoids the problem of incomplete descaling caused by the fish falling too fast, further ensuring that the fish scales can be fully removed and enhancing the descaling effect.

[0060] Furthermore, the sliding cooperation between the movable scraper 333 and the fish scale collecting roller 331 in the fish scale collecting mechanism 33, as well as the function of the return spring 335, enable the movable scraper 333 to adapt to the shape of fish of different sizes and always fit closely to the surface of the fish. This not only effectively improves the fish scale collection effect, but also effectively ensures that the movable scraper 333 has a certain buffering effect when it comes into contact with the fish, avoiding scratching the fish meat, thereby better protecting the integrity and appearance quality of the fish meat.
