[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1 to 5 The present invention discloses a fish meat marinating processing device, comprising: a shell 1, wherein a sauce application mechanism and a pulse vacuum mechanism are provided inside the shell 1;

[0037] The sauce application mechanism includes a conveying assembly for conveying fish meat, and a sauce application assembly for applying sauce to the fish meat is provided inside the conveying assembly;

[0038] The pulse vacuum mechanism includes a vacuum chamber 23 fixed to the inner wall of the outer shell 1. The vacuum chamber 23 contains multiple fish meat clamping components and a drive component for driving the multiple fish meat clamping components to move.

[0039] When using the device of the present invention, the fish meat is first fed into the sauce application mechanism inside the outer shell 1. During this process, the conveying component conveys the fish meat, the sauce application component applies sauce to the fish meat, and then the fish meat with the sauce applied is sent into the vacuum chamber 23. The fish meat is clamped by the fish meat clamping component, and the driving component drives the fish meat clamping component to move, so that different fish meat clamping components clamp the fish meat respectively. Then the vacuum chamber 23 is sealed, and the sauce penetration is accelerated by pulse vacuum.

[0040] The device of the present invention reduces manual contact during the marinating process, alleviating the labor intensity of workers, and accelerates the penetration of sauce through pulsed vacuum, thus shortening the marinating time.

[0041] A coating inlet 4 is provided on the side of the outer shell 1 near the front end of the conveying component. An inclined feed hopper 3 is fixed inside the coating inlet 4. The bottom end of the feed hopper 3 is located inside the outer shell 1 and between the lower roller 14 and the upper roller 33.

[0042] A first waste port 2 is provided on the side wall of the outer shell 1. The first waste port 2 is located at the bottom of the outer shell 1 and the bottom edge is flush with the bottom wall of the outer shell 1. A guide plate 12 is fixedly connected to the bottom wall of the outer shell 1. The top surface of the guide plate 12 is inclined and the bottom end of the guide plate 12 faces the first waste port 2.

[0043] The purpose of setting the first waste outlet 2 and the guide plate 12 is to facilitate the cleaning of the sauce that flows down during the application process;

[0044] Multiple infrared heating lamps 5 are provided on the two opposing inner sidewalls of the outer casing 1 to maintain the temperature inside the outer casing 1 at 50 degrees Celsius-60 degrees Celsius.

[0045] The vacuum chamber 23 has an outlet and a second waste port on one side. A first sealing door 26 is detachably connected to the outlet, and a second sealing door 27 is detachably connected to the second waste port. The first sealing door 26 and the second sealing door 27 are sealed to the vacuum chamber 23. The first sealing door 26 is used to remove the fish meat that has been marinated, and the second sealing door 27 is used to remove the dripping sauce.

[0046] Further optimization of the scheme: the conveying component includes a lower conveying structure and a roller pressing structure. The lower conveying structure includes multiple horizontally arranged lower rollers 14. The multiple lower rollers 14 are arranged sequentially at intervals along the conveying direction of the fish meat. Multiple first protrusions 15 are provided on the outer side wall of the lower rollers 14. The multiple first protrusions 15 are distributed in an array. The lower rollers 14 are rotatably connected to the outer shell 1. One end of the lower rollers 14 extends out of the outer shell 1 and is drivenly connected to a first external power mechanism.

[0047] The scheme is further optimized. The roller pressing structure includes multiple horizontally arranged upper rollers 33, which are arranged one-to-one with multiple lower rollers 14. The upper rollers 33 are located directly above the lower rollers 14. Multiple second protrusions 34 are fixed to the outer side wall of the upper rollers 33, and the multiple second protrusions 34 are distributed in an array.

[0048] The upper roller 33 is rotatably connected to the U-shaped frame 32. The bottom end of the slide rod 31 is fixedly connected to the U-shaped frame 32. The top end of the slide rod 31 is slidably connected to the slide cylinder 9. The slide cylinder 9 is fixedly connected to the outer shell 1 by the fixing rod 8.

[0049] A vertically arranged groove 28 is provided on the inner side wall of the slide cylinder 9. A slider 30 is slidably connected in the groove 28. The slider 30 is fixed to the outer side wall of the slide rod 31. A spring 29 is fixed to the top of the inner wall of the slide cylinder 9. The bottom end of the spring 29 abuts against the top end of the slide rod 31.

[0050] Further optimization of the scheme: the sauce coating component includes a spraying structure and a roller coating structure. The spraying structure includes multiple upper feeding branch pipes 7, which are all connected to an external feeding device through upper feeding pipes 6. The upper feeding branch pipes 7 are located between two adjacent upper rollers 33. A horizontally arranged diverter pipe is fixed to the bottom end of the upper feeding branch pipe 7. The axis of the diverter pipe is parallel to the axis of the upper roller 33. Spray heads are connected to multiple outlets of the diverter pipe.

[0051] The fish meat first slides into the outer shell 1 through the feed hopper 3 and falls between the lower roller 14 and the upper roller 33. The first external power mechanism drives multiple lower rollers 14 to rotate, thereby driving the fish meat to move along the conveying direction. During the movement, the second protrusion 34 and the first protrusion 15 squeeze the fish meat, making it easier for the sauce to penetrate into the fish meat.

[0052] Further optimizing the scheme, the roller coating structure includes multiple lower feeding branch pipes 18, each of which is connected to an external feeding device via a lower feeding pipe 13. A mounting frame 35 is fixedly connected to the top of each lower feeding branch pipe 18, and a fixed cylinder 38 is fixedly connected to the top opening of the mounting frame 35. The fixed cylinder 38 is located between two adjacent lower rollers 14 and is parallel to the lower rollers 14. A flow channel is connected to the fixed cylinder 38, which is located within the mounting frame 35 and connected to the lower feeding branch pipes 18. A rotating cylinder 36 is coaxially rotatably connected to the outer side of the 8. Several first discharge port groups are evenly spaced on the outer side wall of the rotating cylinder 36. The first discharge port groups include multiple first discharge ports 37. The multiple first discharge ports 37 are evenly spaced along the length direction of the rotating cylinder 36. Multiple second discharge ports 39 are opened at the top of the fixed cylinder 38. The multiple second discharge ports 39 are evenly spaced along the length direction of the fixed cylinder 38. The multiple second discharge ports 39 are arranged one-to-one with the multiple first discharge ports 37.

[0053] One end of the rotating drum 36 is coaxially fixed to a gear ring 40, which meshes with a gear. The gear is coaxially fixed to the output shaft of the drive motor 41, and the drive motor 41 is fixed to the mounting bracket 35.

[0054] The sauce enters the fixed cylinder 38 through the lower feed branch pipe 18. The movement of the fish meat drives the rotating cylinder 36 to rotate, thereby causing the first discharge port 37 and the second discharge port 39 to continuously overlap, so that the sauce is spread on the bottom of the fish meat and can effectively reduce the waste of sauce.

[0055] In a further optimized design, a vacuum chamber inlet 20 is provided on one side of the vacuum chamber 23. Multiple auxiliary rods 21 are fixed to the vacuum chamber inlet 20. The multiple auxiliary rods 21 are arranged in parallel and are evenly spaced along the width direction of the vacuum chamber inlet 20. The auxiliary rods 21 are inclined. The high end of the auxiliary rods 21 extends out of the vacuum chamber inlet 20 and is located on one side of the lower roller 14. The top end of the auxiliary rods 21 is lower than the top end of the lower roller 14, and the low end of the auxiliary rods 21 extends into the vacuum chamber 23.

[0056] In a further optimized design, a sealing plate 16 is installed at the vacuum chamber inlet 20. The sealing plate 16 is slidably connected to the outer wall of the vacuum chamber 23 via a guide rail. A flexible sealing strip is fixed to the bottom end of the sealing plate 16. The flexible sealing strip is adapted to the shape of multiple auxiliary rods 21. The output end of a telescopic rod 19 is fixed to the top end of the sealing plate 16. The telescopic rod 19 is fixed to the outer wall of the vacuum chamber 23.

[0057] The scheme is further optimized. The drive component includes two drive rollers 25 rotatably connected in the vacuum chamber 23. The two drive rollers 25 are horizontal and vertically arranged. One end of one drive roller 25 extends out of the vacuum chamber 23 and is connected to a second external power mechanism. Both ends of the drive roller 25 are coaxially fixed with sprockets 24. The two sprockets 24 arranged vertically are connected by a chain 22. Multiple fish meat clamping components are arranged at equal intervals along the chain 22.

[0058] Further optimization of the scheme: the fish meat clamping component includes a second fixing plate 46 fixed between two chains 22. The second fixing plate 46 is horizontally set. Multiple lower support rods 47 are fixed on the second fixing plate 46. The multiple lower support rods 47 are equally spaced along the length direction of the second fixing plate 46. The multiple lower support rods 47 are staggered with multiple auxiliary rods 21. The lower support rods 47 pass through the space between two adjacent auxiliary rods 21 during movement.

[0059] One end of a damping shaft 48 is fixed to the top of the second fixed plate 46, and the other end of the damping shaft 48 is fixed to the first fixed plate 43. A torsion spring 49 is sleeved on the outside of the damping shaft 48. The two ends of the torsion spring 49 abut against the second fixed plate 46 and the first fixed plate 43 respectively. The first fixed plate 43 is arranged parallel to the second fixed plate 46. A plurality of upper pressure rods 45 are fixed to one side of the first fixed plate 43. The plurality of upper pressure rods 45 and the plurality of lower support rods 47 are arranged vertically and vertically respectively. A lever 44 is fixed to the side of the first fixed plate 43 away from the upper pressure rods 45.

[0060] A protrusion is fixed to one side wall of the vacuum chamber 23. When the lever 44 passes the protrusion, the top surface of the lever 44 abuts against the protrusion. At this time, the upper pressure rod 45 and the lower support rod 47 open. When the lever 44 disengages from the protrusion, the upper pressure rod 45 and the lower support rod 47 close.

[0061] As the second fixing plate 46 moves with the chain 22, when the lever 44 passes the protrusion, the protrusion presses the lever 44, causing the upper pressure rod 45 and the lower support rod 47 to open. The lower support rod 47 passes through the auxiliary rod 21 to lift the fish meat. Then the lever 44 separates from the protrusion and clamps the fish meat.

[0062] The scheme is further optimized so that the vacuum chamber 23 is connected to the vacuum machine 10 and the solenoid valve 50, and the solenoid valve 50 is equipped with a filter element 11.

[0063] Work process:

[0064] The fish meat is placed on the feed hopper 3 at the coating inlet 4. The fish meat slides between the lower roller 14 and the upper roller 33. The fish meat moves with the rotation of the lower roller 14. During this process, the diverter sprays the sauce onto the top surface of the fish meat. The rotating drum 36 rotates to coat the bottom surface of the fish meat with the sauce. Both ends of the rotating drum 36 are equipped with baffles 42 to prevent the fish meat from tilting. The drive motor 41 drives the rotating drum 36 to rotate, thereby assisting the movement of the fish meat. At the same time, the upper roller 33 rolls the fish meat.

[0065] The fish meat slides into the vacuum chamber 23 under the action of the auxiliary rod 21. The second fixing plate 46 moves with the chain 22. When the lever 44 passes the protrusion, the protrusion presses the lever 44, causing the upper pressure rod 45 and the lower support rod 47 to open. The lower support rod 47 passes through the auxiliary rod 21 to lift the fish meat. Then the lever 44 separates from the protrusion and clamps the fish meat. Then the vacuum machine 10 draws a vacuum in the vacuum chamber 23. After maintaining the vacuum for a certain period of time, the solenoid valve 50 is opened to introduce air into the vacuum chamber 23. This process is repeated several times until the fish meat is marinated. The fish meat can then be removed.
