Description

Technical Field

[0001] The present invention relates to the technical field of surimi processing equipment. More specifically, the present invention relates to a surimi production and processing device. Background Art

[0002] Surimi is a new type of raw material for aquatic processed foods. After chopping surimi, adding salt, auxiliary raw materials, etc. and then pounding and kneading, it becomes a viscous fish paste. After molding and heating, it becomes an elastic gel. Such products include fish balls, fish cakes, fish sausages, fish rolls, etc. Since surimi products are easy to prepare, tender and delicious, and can be stored for a long time, they are quite suitable for urban consumption. These products can be manufactured on a large scale in factories and can also be produced manually at home. It can not only improve the economic value of low-value fish but also be acceptable to people. Therefore, it is an aquatic product with great development potential.

[0003] When processing surimi, it is necessary to separate the fish bones and fish meat in the fish body, remove the fish bones, retain the fish meat, and then process the fish meat into surimi. In the prior art, a fish meat mincer is generally used to separate fish bones and fish meat. The fish meat mincer uses a meat-collecting barrel with mesh holes and a driving rubber belt to squeeze and move against each other, squeezing the fish meat into the meat-collecting barrel and leaving the fish skin and fish bones outside the meat-collecting barrel. A scraper is fixed inside the meat-collecting barrel, and the scraper scrapes the minced meat and discharges it from the mouth of the meat-collecting barrel. Since the raw material put into the fish meat mincer is large pieces of sliced fish meat, to collect the fish meat more cleanly, it is necessary to reduce the distance between the meat-collecting barrel and the driving rubber belt. However, there are still fish spine bones in this fish meat, and the bone quality is relatively hard. Therefore, this will exert a greater pressure on the main shaft that drives the meat-collecting barrel to rotate, and at the same time increase the frictional resistance of the meat-collecting barrel to rotate and the load of the motor that drives the main shaft to rotate. After a while, the meat-collecting barrel will heat up, resulting in the denaturation of the protein in the collected fish meat, and ultimately making the taste of the deep-processed fish meat products worse. Summary of the Invention

[0004] An object of the present invention is to solve at least the above problems and provide at least the advantages described later.

[0005] To achieve these and other advantages in accordance with the present invention, there is provided a surimi production and processing device, comprising:

[0012] A first motor is further arranged on the lower surface of the substrate in the hopper cover. The output end of the first motor is arranged downward and the output end of the first motor is connected to a scraper. The scraper contacts the upper surface of the pressing plate, so as to scrape the fish meat extruded into the cylinder;

[0013] The diameter of the cylinder is larger than the width of the second conveyor belt, so that one side edge of the cylinder is outside the range of the second conveyor belt. A discharge port is also arranged on the side wall of the cylinder outside the range of the second conveyor belt, so that the fish meat scraped by the scraper is discharged from the discharge port out of the cylinder.

[0014] Preferably, the conveying trough is arranged to rotate on the horizontal plane. The conveying mechanism further includes: a plurality of brackets evenly spaced along the rotation path of the conveying trough for supporting the conveying trough. A rack is provided on the outer bottom surface of the conveying trough. A gear meshing with the rack is rotatably provided on the bracket. The wheel shaft of the gear extends outside the bracket and is coaxially connected to a driven wheel. A second motor is provided beside the bracket.

[0021] The present invention has at least the following beneficial effects: The fish mince production and processing device of the present application adopts two separation processes for the separation of fish bones. The first is rough bone separation, and the second is fine bone separation, thus avoiding the disadvantages of large wear on the existing fish meat mincer by thick fish bones, high equipment load and easy heating, and also avoiding the disadvantage of thick fish bones breaking in the fish meat and increasing the separation difficulty. At the same time, when separating the thick bones, the separating cutter cuts the fish meat along the texture of the fish bones and fish meat fibers, which can not only separate the fish meat and thick fish bones more easily and thoroughly, but also cause less wear on the separating cutter.

[0022] Other advantages, objectives and features of the present invention will be partially reflected by the following description, and partially will be understood by those skilled in the art through the research and practice of the present invention. Description of the Drawings

[0027] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0028] It should be noted that, unless otherwise specified, the experimental methods described in the following implementation schemes are all conventional methods, and the reagents and materials, unless otherwise specified, can all be obtained from commercial channels; in the description of the present invention, the terms "horizontal", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0029] As Figures 1 to 4 shown, the present invention provides a surimi production and processing device, including:

[0030] A conveying mechanism, which includes a conveying groove 1 with a spacing matching the thickness of the fish body, so that the scaled and gutted fish body is transported in the conveying groove 1 with the fish belly facing up;

[0031] Here, the fish is generally gutted by making a cut in the fish belly and taking out the fish internal organs from it. Therefore, a cut will be left at the fish belly, which leaves an entrance for the subsequent fish belly filling block 4 to wedge into the fish belly.

[0032] Turning mechanism, which includes a first conveyor belt 2 arranged above the conveying trough 1 and a connecting rod 3 arranged on the first conveyor belt 2. A fish belly filling block 4 with a triangular cross-section is arranged at the end of the connecting rod 3, so that when the connecting rod 3 rotates to the lower layer of the first conveyor belt 2 with the first conveyor belt 2, the fish belly filling block 4 wedges into the fish belly, and then when the connecting rod 3 rotates to the upper layer of the first conveyor belt 2 with the first conveyor belt 2, the fish body is turned over and lifted;

[0033] After the fish belly filling block 4 wedges into the fish belly here, it can support the fish belly, facilitating the subsequent separation of the fish meat along the thick fish bone by the separation cutter 8.

[0034] Here, the brackets of the first conveyor belt 2 can be arranged on both sides of the conveying mechanism, and the driving motor of the first conveyor belt 2 can be arranged on the ground to drive the first conveyor belt 2 to move through belt transmission;

[0035] Thick bone separation mechanism, which includes a top plate 5 arranged above the turning mechanism. A first hydraulic cylinder 6 that extends downward and faces the first conveyor belt 2 is arranged on the lower surface of the top plate 5. A knife seat plate 7 is connected to the piston rod of the first hydraulic cylinder 6. A pair of elastic separation cutters 8 are arranged on the knife seat plate 7. The distance between the pair of separation cutters 8 is slightly larger than the width of the fish dorsal fin, so that when the first hydraulic cylinder 6 extends, the pair of separation cutters 8 separate the fish meat along both sides of the fish dorsal fin;

[0036] The thick fish bone here generally refers to the relatively thick and obvious bones in the fish body, such as the spine bone, rib bone, and dorsal fin bone. Except for the end connected to the knife seat plate 7, the other three sides of the separation cutter 8 can be provided with cutting edges, so that the cutting resistance to the fish body is smaller.

[0037] Here, the top plate 5 can be fixedly connected to the ceiling through a rod body, or can be supported by legs arranged at the four corners of the lower surface of the top plate 5. Of course, at this time, the width of the top plate 5 needs to be greater than the width of the conveying mechanism.

[0038] Among them, second conveyor belts 9 are also arranged on both sides of the turning mechanism. The upper layer of the first conveyor belt 2 is higher than the upper layer of the second conveyor belt 9, and an inclined plate 10 is arranged between the upper layer of the first conveyor belt 2 and the upper layer of the second conveyor belt 9, so that the separated fish meat slides onto the second conveyor belt 9 along the inclined plate 10. A fine bone separation mechanism for further separating the fine bones in the fish meat is also arranged above the second conveyor belt 9;

[0039] The fine bone separation mechanism here can be similar to the existing fish meat extractor. Using the second conveyor belt 9 as the rubber belt in the existing fish meat extractor, a meat extraction barrel that rotates relative to the second conveyor belt 9 is arranged above the second conveyor belt 9, and a fixed scraper is arranged in the meat extraction barrel. However, this fine bone separation mechanism operates continuously, and the long-term friction between the scraper and the meat extraction barrel easily causes the temperature to rise, resulting in the denaturation of fish meat protein, thus affecting the taste of subsequent deep-processed fish meat products. Therefore, the fine bone separation mechanism is improved in the subsequent embodiments of this application.

[0040] Wherein, a thick bone placement groove 11 is further arranged above the flipping mechanism. The thick bone placement groove 11 is located at a position behind the first hydraulic cylinder 6 on the moving path of the connecting rod 3. Slits 12 for the connecting rod 3 to pass through are arranged on the side wall and the bottom of the thick bone placement groove 11. A first through hole 13 for the fish belly filling block 4 to pass through and abut against the fish bone is further arranged at the bottom of the thick bone placement groove 11.

[0041] Here, since only the connecting rod 3 can pass through the slit 12 on the side wall of the thick bone placement groove 11, and the widths of the fish bone and the fish belly filling block 4 are wider than that of the connecting rod 3. To prevent the fish bone and the fish belly filling block 4 from hitting the outer wall of the thick bone placement groove 11, generally, the top height of the thick bone placement groove 11 is set lower than the bottom of the fish belly filling block 4. In this way, when the connecting rod 3 enters the thick bone placement groove 11 from the slit 12, the fish bone and the fish belly filling block 4 can enter the thick bone placement groove 11 without obstruction from the top of the thick bone placement groove 11.

[0042] When the above embodiment is used, the scaled and deveined fish body is first placed in the conveying trough 1 with the belly facing upward, and the conveying trough 1 is used to convey the fish body to the bottom of the flipping mechanism. When the first conveyor belt 2 moves to drive the connecting rod 3 and the fish belly filling block 4 at the end thereof to rotate to the lower layer of the first conveyor belt 2, the fish belly filling block 4 is wedged into the fish belly, and then when the connecting rod 3 rotates to the upper layer of the first conveyor belt 2 along the first conveyor belt 2, the fish body is flipped and lifted. When the fish body on the connecting rod 3 moves to the bottom of the coarse bone separation mechanism, the first hydraulic cylinder 6 is started to extend its piston rod, and the pair of separation cutters 8 cut into the fish meat along both sides of the dorsal fin of the fish. Since the separation cutter 8 is elastic, it can bend when it touches the coarse bone of the fish and cut the lower fish meat along the coarse bone of the fish. In this way, the fish meat is cut along the texture of the fish bones and the fish meat fiber, which can not only separate the fish meat and the coarse bone of the fish more easily and thoroughly, but also reduce the wear of the separation cutter 8. When the fish meat is cut into large pieces, the piston rod of the first hydraulic cylinder 6 contracts, waiting for the next connecting rod 3 and the fish body above it to be transported. Only the fish skeleton is left after the fish meat is cut off. At this time, the connecting rod 3 carries the fish skeleton and continues to move with the first conveyor belt 2. When the connecting rod 3 carries the fish skeleton into the coarse bone receiving groove 11, when the first conveyor belt 2 is transferred from the upper layer to the lower layer, since the connecting rod 3 can pass through the slit 12 at the bottom of the coarse bone receiving groove 11, the fish belly filling block 4 can pass through the first through hole 13, and the fish skeleton is pressed against the bottom of the coarse bone receiving groove 11, the fish belly filling block 4 can be separated from the fish skeleton, and the fish skeleton is left in the coarse bone receiving groove 11, while the connecting rod 3 and the fish belly filling block 4 move to the lower layer of the first conveyor belt with the first conveyor belt, and continue to flip and lift another fish body. On the other hand, after the large pieces of fish meat are cut, they slide along the inclined plate 10 onto the second conveyor belt 9, and then the fine bones and fish meat are separated by the fine bone separation mechanism above the second conveyor belt 9, thereby realizing the assembly line production and processing of fish paste.

[0043] It is not difficult to find from the above embodiments and their use process that the fish paste production and processing device described in the present application adopts two separation processes for separating fish bones, the first separation of coarse bones and the second separation of fine bones, thereby avoiding the disadvantages of large wear and tear of the existing fish meat harvester caused by large bone spurs, high equipment load, and easy heating, and also avoiding the disadvantages of large bone spurs breaking in the fish meat and increasing the difficulty of separation. At the same time, when separating coarse bones, the separation cutter 8 cuts the fish meat along the texture of the fish bones and fish meat fibers, which can not only easily and thoroughly separate the fish meat and coarse bones, but also reduce the wear and tear of the separation cutter 8.

[0044] In another embodiment, the fine bone separation mechanism includes: a second hydraulic cylinder 14 which is arranged on the lower surface of the top plate 5 and extends downwardly facing the second conveyor belt 9. A base plate 15 is connected to the piston rod of the second hydraulic cylinder 14. A horn-shaped hopper cover 16 is connected to the lower surface of the base plate 15. A cylinder 17 is connected to the lower end of the hopper cover 16. A pressing plate 18 is arranged at the lower end of the cylinder 17. A plurality of small holes for extruding fish meat are arranged on the pressing plate 18. A support plate for supporting the upper layer of the second conveyor belt 9 is fixedly arranged below the upper layer of the second conveyor belt 9;

[0045] A first motor 19 is further arranged on the lower surface of the base plate 15 in the hopper cover 16. The output end of the first motor 19 is arranged downward and the output end of the first motor 19 is connected to a scraper 20. The scraper 20 contacts the upper surface of the pressing plate 18 for scraping the fish meat extruded into the cylinder 17;

[0046] The diameter of the cylinder 17 is larger than the width of the second conveyor belt 9, so that one side edge of the cylinder 17 is outside the range of the second conveyor belt 9. The length of the scraper 20 is adapted to the inner diameter of the cylinder 17. A discharge port 21 is further arranged on the side wall of the cylinder 17 outside the range of the second conveyor belt 9, so that the fish meat scraped by the scraper 20 is discharged from the discharge port 21 out of the cylinder 17.

[0047] When in use in the above embodiment, when the large piece of fish meat slides down along the inclined plate 10 onto the second conveyor belt 9, the piston rod of the second hydraulic cylinder 14 extends, and the pressing plate 18 moves downward with the piston rod of the second hydraulic cylinder 14 and presses the fish meat on the second conveyor belt 9. Since the support plate is arranged below the upper layer of the second conveyor belt, the upper layer of the second conveyor belt will not sink. After the fish meat on the second conveyor belt 9 is pressed, the crushed fish meat enters the cylinder 17 through the small holes on the pressing plate 18. Then, the first motor 19 is started to drive the scraper 20 to rotate, so as to scrape the crushed fish meat on the upper surface of the pressing plate 18 in the cylinder 17 into a mass. Since the length of the scraper 20 is adapted to the inner diameter of the cylinder 17, and the discharge port 21 on the cylinder 17 is arranged outside the range of the second conveyor belt 9, when the scraper 20 pushes the mass of crushed fish meat to move, it passes through the discharge port 21, so that the mass of crushed fish meat will be discharged from the discharge port 21. Then, the piston rod of the second hydraulic cylinder 14 contracts, and the second conveyor belt 9 moves to move the fish skin and fine fish bones remaining on the upper layer of the second conveyor belt away from below the fine bone separation mechanism. The subsequent belt surface of the second conveyor belt 9 can continue to receive the large pieces of fish meat sliding down from the inclined plate 10 and repeat the above process. After the fish skin and fine fish bones on the upper layer of the second conveyor belt 9 move to the end of the upper belt surface of the second conveyor belt 9, they can fall from the belt surface, which is convenient for subsequent continuous production.

[0048] It is not difficult to find from the above embodiments and their usage processes that since the separation process of the fine bones in the fish meat starts when the piston rod of the second hydraulic cylinder 14 extends and the pressing plate 18 presses against the upper layer of the second conveyor belt 9, and is completed when the piston rod of the second hydraulic cylinder 14 contracts and the pressing plate 18 moves away from the upper layer of the second conveyor belt 9, and this process is repeated subsequently. Therefore, the fine bone separation process is carried out intermittently, which can not only better separate the fine fish bones in the fish meat, but also avoid the disadvantages of the fish meat protein denaturation and the poor taste caused by the rapid temperature rise of the equipment due to long-term continuous operation.

[0049] In another embodiment, the conveying trough 1 is arranged to rotate on the horizontal plane. The conveying mechanism further includes: a plurality of brackets arranged at equal intervals along the rotation path of the conveying trough 1 for supporting the conveying trough 1. A rack 22 is provided on the outer bottom surface of the conveying trough 1. A gear 23 meshing with the rack 22 is rotatably provided on the bracket. The wheel shaft of the gear 23 extends outside the bracket and is coaxially connected to a driven wheel. A second motor 24 is provided beside the bracket. A driving wheel is provided on the output shaft of the second motor 24. The driving wheel is connected to the driven wheel by a belt drive, so that the second motor 24 drives the conveying trough 1 to rotate.

[0050] Specifically, the bracket includes: a base 25; a pair of vertical plates 26 provided on the base 25. The conveying trough 1 is arranged between the pair of vertical plates 26. Bottom supports 27 supporting the bottom surface of the conveying trough 1 are provided on the opposite surfaces of the pair of vertical plates 26. A gap is left between the two bottom supports 27 for the rack 22 to pass through.

[0051] The gear 23 is arranged between the pair of vertical plates 26. One end of the wheel shaft of the gear 23 is rotatably connected to one vertical plate 26, and the other end passes through the other vertical plate 26 and extends outside the bracket.

[0052] The rotation arrangement here means that the conveying trough 1 is a polygon with its head and tail connected on the horizontal plane. In this way, the turning mechanism, the coarse bone separation mechanism, and the fine bone separation mechanism can be arranged along one side of the polygon, and other processes can be set on the other sides of the polygon, such as the automatic fish scale removal process, the automatic fish viscera removal process, and so on.

[0053] When the above embodiment is used, the second motor 24 drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate through the belt drive. Since the driven wheel and the gear 23 are coaxial, the gear 23 also rotates with the driven wheel. Then the rack 22 meshing with the gear 23 also moves under the drive of the gear 23, thus realizing the movement of the conveying trough 1.

[0054] In another embodiment, the second motor 24, the drive motor of the first conveyor belt 2, and the drive motor of the second conveyor belt 9 are all stepper motors. The length of one step of the conveying trough 1, the length of one step of the first conveyor belt 2, and the length of one step of the second conveyor belt 9 are the same. In this way, there is no need for manual control of the start and stop of the conveying mechanism, the flipping mechanism, and the fine bone separation mechanism, which is more convenient to use and also reduces the labor cost.

[0055] In another embodiment, the material of the conveying trough 1 is hard rubber. Since hard rubber has a certain roughness, it can better fix the fish body and prevent the fish body from slipping back and forth when the motion state of the fish body in the conveying trough 1 changes, which is not conducive to finding the correct working position.

[0056] In another embodiment, the hopper cover 16 is provided with an air inlet hole and an air outlet hole. The air inlet hole is communicated with a cold air pipe for introducing cold air into the hopper cover 16 to cool it down. In this way, the temperature in the cylinder 17 can be further reduced, and the influence of equipment operation heating on the fish meat can be reduced.

[0057] In another embodiment, a fish meat collection bucket 28 is provided beside the second conveyor belt 9 and below the discharge port 21, which is convenient for collecting the shredded fish meat.

[0058] Although the embodiments of the present invention have been disclosed above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
