Description

Technical Field

[0001] The invention relates to the technical field of fish processing, in particular to a fish scale processing device for fish gelatin production. Background Art

[0002] Gelatin is produced by hydrolyzing collagen from the skin or bones of mammals such as pigs and cattle, and can be widely used in medicine, food and other fields. However, due to the impact of mad cow disease (BSE), foot-and-mouth disease (FDA) and poison capsules, the safety of mammalian gelatin has been questioned. Studies have found that fish scales are rich in collagen, and fish gelatin and mammalian gelatin have similar properties.

[0003] Before extracting fish gelatin from fish scales, a fish scale remover is usually required to remove the scales of the fish, so as to facilitate the collection of the scales. The fish scale remover mainly achieves the purpose of scraping the scales through a scraping mechanism.

[0004] For example, the announcement number CN115530219B discloses a fish scale removal mechanism, including: a connecting frame, a removal mechanism, a water supply mechanism, and a fish scale removal mechanism; wherein the upper surface of the connecting frame is provided with a mounting piece; the removal mechanism is composed of a first fixed column, a second fixed column, two fixed rings, a rubber tube, and a plurality of hooks; the water supply mechanism is composed of a water pump, a water supply pipe, four third fixed columns, two water storage barrels, and four fixed pipes. The fish scale removal mechanism can scrape off the fish scales on both sides of the fish when the two rubber tubes rotate in opposite directions. The larger the size of the fish body, the greater the outward deformation of the two rubber tubes, and the wider the scraping range. By driving the two groups of fish scale removal mechanisms to rotate in opposite directions, the scraping mechanism scrapes off the fish scales. Under the pulling force of multiple groups of first springs, not only the scraping effect of the fish scale hook is improved, but also the scraping mechanism can fully clean the fish scales. The water in the guide wheel is sprayed out from multiple placement slots to clean the fish scale hooks and the fish scales adhering to the fish body.

[0005] The announcement number CN119073373A provides an automatic fish descaling device and a method of using the same, which belongs to the technical field of descaling machines. The automatic fish descaling device includes: a descaling machine box, which can be used to install an adjustment mechanism and a descaling mechanism. The upper end of the descaling machine box is fixedly connected to a support frame, which can be used to install a first motor; an adjustment mechanism, the adjustment mechanism includes: a first motor, a swing rod, two docking rods, two connecting rods, two pull rods, four slide rods and two slide boxes, the first motor is fixedly connected to the upper end of the support frame, which can be used to drive the swing rod to rotate, and the swing rod is fixedly connected to the output end of the first motor. When the fish moves in the descaling machine box, the third scraping tooth will scrape the fish scales on the upper surface of the fish, which can reduce the fish scales on the surface of the fish. The order of the multiple first scraping teeth and the second scraping teeth on the rotating shaft enables the multiple first scraping teeth and the second scraping teeth to drive the fish to be discharged through the discharge pipe, thereby achieving the effect of scraping the fish scales of fish of different sizes.

[0006] However, when the above technology is actually used, it has requirements on the posture of the fish entering the device, and its adaptability is poor, and the scale removal effect on fish of different sizes is different. Summary of the invention

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1.

[0027] 3. The present invention also requires that when cleaning the fish scales between the first scraping brush and the second scraping brush, there should be no fish inside the outer cylinder. At this time, hot water is sprayed onto the outer cylinder through the high-temperature spray port arranged on the inner wall of the protective cover, wherein the first scraping brush and the second scraping brush are both temperature-sensitive materials of styrene-ethylene / butylene-styrene block copolymer. This makes the first scraping brush and the second scraping brush show a higher hardness during the stage of scraping fish scales, but will not cause a greater impact on the fish meat, making it convenient to scrape the fish scales. At that time, the same fish scales will stick to the gap between the first scraping brush and the second scraping brush. When the step of cleaning the fish scales is performed, hot water above 60° will soften the first scraping brush and the second scraping brush, which are styrene-ethylene / butylene-styrene block copolymer, and as the spiral conveying blades and the conveying cushion continue to spirally convey, the fish scales will fall from the spiral notch and the porous structure of the fish baffle to the discharge bin for collection.

[0050] The inner cylinder assembly includes an inner cylinder 601, and the inner cylinder 601 cooperates with the outer cylinder 401 to restrict the fish between the two so as to adjust the posture of the fish. A second air bag 602 is fixedly installed on the surface of the inner cylinder 601, so that the second air bag 602 is inflated to cooperate with the first air bag 403 to wrap the fish. One end of the inner cylinder 601 corresponding to the position of the spiral notch 402 is conical, so as to facilitate the fish to enter the outer cylinder 401. A second support frame 603 is fixedly installed on the inner wall of the inner cylinder 601, and a driving shaft 604 for driving the inner cylinder 601 to rotate is fixedly installed in the middle of the second support frame 603. The second support frame 603 is driven by a driving motor in conjunction with a gear.

[0060] When the above structure is in use, by pumping air into the interior of the driving shaft 604, the gas is filled into the first air bag 403 through the first inflation ring 901 and the connecting tube 903, and is filled into the interior of the second air bag 602 through the second inflation ring 902, and the first air bag 403 cooperates with the second air bag 602 to reduce the space between the inner cylinder 601 and the spiral conveying blade 501 and the space between the outer cylinder 401 and the spiral conveying blade 501, thereby achieving the purpose of lightly wrapping the fish with the first air bag 403 and the second air bag 602, thereby facilitating the descaling operation.

[0061] The inner wall of the protective cover 3 is provided with a high-temperature spray port (not shown), and the high-temperature spray port corresponds to the position of the spiral notch 402, so that the hot water sprayed from the high-temperature spray port can soften the first scraping brush 701 and the second scraping brush 702 and remove the fish scales, and at the same time, the interior of the outer cylinder 401 is sterilized at high temperature;

[0062] When the above structure is in use, hot water is sprayed onto the outer cylinder 401 through the high-temperature spray port arranged on the inner wall of the protective cover 3, wherein the first scraping brush 701 and the second scraping brush 702 are both temperature-sensitive materials of styrene-ethylene / butylene-styrene block copolymer, which makes the first scraping brush 701 and the second scraping brush 702 exhibit a higher hardness during the stage of scraping fish scales, but will not cause a greater impact on the fish meat, making it convenient to scrape the fish scales. When the high-temperature spray port sprays hot water above 60°, the first scraping brush 701 and the second scraping brush 702 made of styrene-ethylene / butylene-styrene block copolymer will be softened, and as the spiral conveying blades 501 and the conveying cushion 503 continue to spirally convey, the fish scales will fall from the spiral notch 402 and the porous structure of the fish baffle 2 into the discharge bin 1 for collection.

[0063] Working principle: When in use, the invention allows fish to enter the interior of the outer cylinder 401 from the feed hopper 10. Since the discharge bin 1, the outer cylinder assembly, the feeding assembly and the inner cylinder assembly are all inclined toward one end of the fish baffle 2, the fish will naturally enter the interior of the outer cylinder 401. At the same time, by pumping air into the interior of the drive shaft 604, the gas is filled into the interior of the first air bag 403 through the first inflation ring 901 and the connecting pipe 903, and is filled into the interior of the second air bag 602 through the second inflation ring 902, and the first air bag 403 cooperates with the second air bag 602 to reduce the space between the inner cylinder 601 and the spiral conveying blade 501 and the outer cylinder 401 and the spiral conveying blade 501. At this time, the driving motor cooperates with the gear to drive the driving shaft 604 to rotate, and the driving shaft 604 drives the inner cylinder 601 to rotate through the second support frame 603;

[0064] When the inner cylinder 601 rotates, the driven gear 804 between the inner cylinder 601 and the end ring 502 will be driven to rotate, and then the inner cylinder 601 drives the end ring 502 to rotate through the driven gear 804. When the end ring 502 rotates, the driven gear 804 between the end ring 502 and the outer cylinder 401 will be driven to rotate, and then the end ring 502 drives the outer cylinder 401 to rotate through another driven gear 804. At the same time, the rotation direction of the end ring 502 is opposite to the rotation direction of the inner cylinder 601 and the outer cylinder 401.

[0065] When the spiral conveying blade 501 cooperates with the conveying cushion 503 to convey the fish, due to the spiral action of the spiral conveying blade 501 and the conveying cushion 503, the fish tends to be in a tilted state, and the first air bag 403 cooperates with the second air bag 602 to reduce the space between the inner cylinder 601 and the spiral conveying blade 501 and the outer cylinder 401 and the spiral conveying blade 501, so that the fish is in a horizontal state and is wrapped by the first air bag 403 and the second air bag 602. Since the rotation direction of the spiral conveying blade 501 is opposite to the rotation direction of the inner cylinder 601 and the outer cylinder 401, the fish will produce relative movement with the first scraping brush 701 and the second scraping brush 702 under the action of tilting and the conveying of the spiral conveying blade 501 and the conveying cushion 503, wherein the spiral notch 402, the first air bag 403, the first scraping brush 701 and the second scraping brush 702 are evenly distributed. The outer cylinder 401 is a spiral structure, wherein the curvatures of the spiral notch 402, the first air bag 403, the first scraping brush 701 and the second scraping brush 702 are the same, and the spiral directions of the middle parts of the spiral notch 402, the first air bag 403, the first scraping brush 701 and the second scraping brush 702 are changed symmetrically for many times, so that no matter how the fish is oriented, when the first scraping brush 701 and the second scraping brush 702 move relative to the fish, the first scraping brush 701 and the second scraping brush 702 always move relative to each other in the opposite direction of the fish scales at certain positions of the outer cylinder 401, and the fish scales are scraped off, so that the fish posture does not need to be adjusted in advance, which greatly improves the efficiency of scraping the fish scales. At the same time, the first air bag 403 and the second air bag 602 are used to slightly wrap the fish, and the relative movement of the first scraping brush 701 and the second scraping brush 702 with the fish is coordinated, so that the scales of fish of different sizes can be completely scraped off;

[0066] After the fish scales are scraped off, the fish will be further transported to the position of the fish discharging rack 404 by the spiral conveying blade 501 and the conveying cushion 503, and will fall from the fish discharging rack 404 to the fish baffle plate 2 to be discharged. During the process of scraping off the fish scales by the first scraping brush 701 and the second scraping brush 702, the fish scales will fall into the discharging bin 1 through the spiral notch 402 and will fall into the discharging bin 1 through the porous structure of the fish baffle plate 2 to be collected.

[0067] A first support arm 803, a second support arm 805 and a third support arm 806 are provided, wherein grooves are provided at one end of the first support arm 803 and the second support arm 805 corresponding to the side wall positions of the outer cylinder 401, the inner cylinder 601 and the end ring 502, and balls are provided on the inner walls of the grooves, so that the outer cylinder 401, the inner cylinder 601 and the end ring 502 rotate on the inner walls of the grooves, and the outer cylinder 401, the inner cylinder 601 and the end ring 502 are supported by the first support arm 803 and the second support arm 805, and grooves and balls are also provided at one end of the third support arm 806 corresponding to the side wall positions of the end ring 502 and the outer cylinder 401, and the end ring 502 and the outer cylinder 401 are supported by the third support arm 806;

[0068] When it is necessary to clean the fish scales between the first scraping brush 701 and the second scraping brush 702, it is required that there is no fish inside the outer cylinder 401. At this time, hot water is sprayed onto the outer cylinder 401 through the high-temperature spray port arranged on the inner wall of the protective cover 3. The first scraping brush 701 and the second scraping brush 702 are both made of a temperature-sensitive material of styrene-ethylene / butylene-styrene block copolymer. This makes the first scraping brush 701 and the second scraping brush 702 have a higher hardness during the stage of scraping fish scales, but will not cause a significant impact on the fish meat. The fish scales will stick to the gap between the first scraping brush 701 and the second scraping brush 702 when cleaning the fish scales. Hot water above 60° will soften the first scraping brush 701 and the second scraping brush 702, which are styrene-ethylene / butylene-styrene block copolymers. As the spiral conveying blades 501 and the conveying cushion 503 continue to spirally convey, the fish scales will fall from the spiral notch 402 and the porous structure of the fish baffle 2 to the discharge bin 1 for collection.
