Description

Technical Field

[0001] This utility model relates to the field of marinating and processing braised meat, specifically an automatic spray marinating device for color protection processing of braised meat products. Background Technology

[0002] In the color-protecting processing of braised meat products (such as duck tongues and duck necks), automatic spray marinating devices can significantly improve the penetration efficiency of color-protecting agents and braising liquid, while reducing oxidative discoloration. These devices include a spraying system, a marinating chamber, and a circulation system. The spraying system typically uses rotating nozzles with a frequency converter to control the pressure, spraying the meat raw materials. However, while most existing nozzles achieve a rotating spraying effect, their limited spray diameter makes it impossible to quickly adjust the spray diameter according to the area of ​​the meat raw materials to be sprayed, ensuring thorough spraying.

[0003] In response, this technical solution proposes an automatic spray marinating device for color protection processing of braised meat products. Utility Model Content

[0004] The purpose of this invention is to provide an automatic spray marinating device for color protection processing of braised meat products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic spraying and marinating device for color protection processing of braised meat products includes a meat spraying platform, a rotating nozzle, and a marinating liquid tank. The meat to be marinated is laid on the spraying platform. Nozzle bases are distributed above the spraying platform, and a marinating liquid tank is installed on the upper part of the nozzle bases. The bottom of the marinating liquid tank is connected to a rotating nozzle located in the middle of the bottom of the nozzle bases via a transmission pipe. The rotating nozzle is used to perform adjustable rotating spraying on the braised meat on the spraying platform. An adjustable rotating mechanism is connected to one side of the nozzle bases to control the rotating nozzles at the bottom to rotate around the center of the spraying platform and to adjust the rotation radius of the rotating nozzles, ensuring comprehensive spraying of braised meat with different areas on the spraying platform, thereby ensuring the usability of the device during operation.

[0007] Compared with the prior art, the beneficial effects of this utility model are: the radius of the nozzle base can be infinitely adjusted by an adjustable rotating mechanism (main servo motor, ball screw, etc.) to adapt to different meat spreading areas.

[0008] The U-shaped moving plate and the sliding groove work together to ensure motion stability, while the T-shaped rotating column and T-shaped rotating hole design prevent dislocation.

[0009] The smoothness of the nozzle oscillation is achieved through the sliding connection structure between the sleeve and the slide rod. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Please see Figures 1-2 An automatic spraying and marinating device for color protection processing of braised meat products includes a meat spraying platform 10, a rotating nozzle 11, and a marinating liquid tank 13. The meat spraying platform 10 is covered with braised meat to be marinated. Nozzle bases 12 are distributed above the meat spraying platform 10. A marinating liquid tank 13 is installed on the upper part of the nozzle bases 12. The bottom of the marinating liquid tank 13 is connected to a rotating nozzle 11 located at the center of the bottom of the nozzle bases 12 via a transmission pipe. The rotating nozzle 11 is used to perform adjustable rotating spraying on the braised meat on the meat spraying platform 10. An adjustable rotating mechanism is connected to one side of the nozzle bases 12 to control the nozzle bases 12 to drive the rotating nozzle 11 at the bottom to rotate and spray around the center of the meat spraying platform 10, and to adjust the rotation radius of the rotating nozzle 11 to ensure that the braised meat with different areas on the meat spraying platform 10 is sprayed in a covering manner, thereby ensuring the usability of the device during operation.

[0020] The adjustable rotation mechanism includes a rotation component and an adjustment component. The rotation component includes a main servo motor 15, the output shaft of which is longitudinally distributed and a rotating disk 16 is mounted on its top. The adjustment component is radially distributed and mounted on the upper side of the rotating disk 16. The adjustment component includes a rectangular adjustment box 17 radially distributed and fixedly mounted on the upper side of the rotating disk 16. The top of the rectangular adjustment box 17 is provided with an opening. A ball screw 19 is rotatably arranged inside the rectangular adjustment box 17 along its length. One end of the ball screw 19 is connected to a connecting shaft that moves through to the outside of the rectangular adjustment box 17. The end of the connecting shaft is connected to a servo motor 18 fixed on the upper side of the rotating disk 16. A ball nut is threadedly connected to the ball screw 19. A guide device for limiting the rotation of the ball nut is provided on the ball nut. A set of U-shaped moving plates 20 is connected to the top of the ball nut. The two sides of the U-shaped moving plates 20 slide along the two sides of the rectangular adjustment box 17. That is, while the ball nut moves along the ball screw 19, it drives the U-shaped moving plates 20 to move along the length of the rectangular adjustment box 17.

[0021] The rotating assembly also includes a connecting block 23 connected to the top center of the U-shaped moving plate 20 via a limiting rotating member. Two connecting rods 26 are connected to the side of the connecting block 23 facing the nozzle base 12. When the main servo motor 15 drives the rotating disk 16 to rotate, it drives the U-shaped moving plate 20 on the upper side of the rectangular adjustment box 17 to rotate, thereby synchronously driving the two connecting rods 26 to rotate. Each of the two connecting rods 26 is fitted with a sleeve 27. The bottom of the two sleeves 27 is connected to two sleeves 29 that are perpendicular to the sleeves 27 via a connecting base plate 28. The middle of the two sleeves 29 slides. A sliding rod 30 is connected, with both ends of the sliding rod 30 installed inside a U-shaped base plate 31. That is, while the connecting rod 26 swings, it controls the second sleeve 29 to slide along the sliding rod 30. At the same time, the ends of the two connecting rods 26 away from the connecting block 23 are fixedly connected to the nozzle base 12, thereby realizing the rotation drive of the nozzle base 12. Then, in conjunction with the movement of the U-shaped moving plate 20 on the rectangular adjustment box 17, the adjustment of the radial position of the connecting block 23 on the upper part of the rotating disk 16 is adjusted, thereby adjusting the swing radius of the nozzle base 12, so as to achieve the coverage spraying of different braised meats on the braised meat spraying station 10.

[0022] In this embodiment of the invention, multiple circularly spaced partition grooves 14 are provided on the upper surface of the meat spraying station 10 along the radial direction. These grooves are used to increase the anti-slip properties of the meat placed on the meat spraying station 10 for marinating. At the same time, the marinating liquid after spraying can penetrate the meat and be stored along a certain path, which is also conducive to subsequent discharge.

[0023] A solenoid valve is installed on the transfer pipe or the rotary nozzle 11 to control the transfer of the marinating liquid in the marinating liquid tank 13;

[0024] For the rotating nozzle 11, a common rotating nozzle can be used. That is, when the rotating nozzle 11 is running, it rotates and sprays while rotating around the center of the meat spraying station 10, thereby expanding the spraying range.

[0025] In one embodiment of the present invention, the pickling solution in the pickling tank 13 needs to be determined according to the requirements for pickling and color protection. Common spray pickling includes three stages: pretreatment stage:

[0026] The duck tongue is vacuum tumbled (5 minutes, vacuum degree -0.08MPa) to open up the muscle fibers.

[0027] Spray marinating:

[0028] Initial spray (5 minutes): Pure color-protecting agent solution (e.g., 0.3% sodium isocyanate + 0.1% citric acid)

[0029] Main spray (20 minutes): Brine circulates and sprays (8 rpm).

[0030] Final spray (3 minutes): Secondary strengthening with color-protecting agent

[0031] Static infiltration:

[0032] Tilt the meat spraying station 10 and let it stand for 10 minutes (to promote the absorption of residual droplets).

[0033] The above-mentioned time settings can be adjusted adaptively according to specific circumstances, and are not subject to mandatory constraints.

[0034] It should be noted that, regarding the aforementioned ball screw 19, ball nut, and designed guide device, the thread raceway accuracy of ball screw 19 is as follows:

[0035] It must meet at least ISO P5 level, with a raceway surface roughness Ra≤0.4μm;

[0036] End support design: A thrust bearing mounting position (to withstand axial force) needs to be reserved, and a keyway or set screw hole needs to be machined at the end of the lead screw shaft (to prevent rotation and fixation).

[0037] Special treatment: pre-stretch installation (to compensate for thermal expansion), surface chrome plating or nitriding (abrasion resistance ≥ HV800);

[0038] Ball nut anti-rotation interface: The outer circle needs to be machined with a keyway / flat surface (to mate with the guide device).

[0039] Internal circulation structure: adopts end cap type return device (reduces the risk of ball jamming), and the chamfer R of the ball channel is ≥ 1.5 times the diameter of the steel ball;

[0040] Preload adjustment: The double-nut structure requires adjustable preload (to eliminate axial clearance), and the preload amount is usually 5-8% of the rated dynamic load;

[0041] The guiding device can be a guide rod-bushing type, that is, the optical axis guide rod is installed parallel to the ball screw 19, and the ball nut is connected to the guide rod through the linear bearing / copper bushing, or a flange-guide rail type (integrated solution) can be used, that is, the ball nut flange is fixed to the linear slide by bolts, and the slide has a built-in ball guide rail to undertake the guiding function. The specific operation and structural design can refer to the existing screw nut transmission mechanism, which will not be elaborated here.

[0042] As a preferred embodiment of the present invention, see [reference]. Figure 3 The limiting rotating component includes a T-shaped rotating column 24 installed at the top center of the U-shaped moving plate 20. A T-shaped rotating hole 25 is opened at the bottom of the connecting block 23 corresponding to the T-shaped rotating column 24. The T-shaped rotating column 24 is placed in the T-shaped rotating hole 25 and rotates, thus maintaining the anti-detachment rotation between the U-shaped moving plate 20 and the connecting block 23.

[0043] See Figure 4The U-shaped moving plate 20 has sliders 21 symmetrically installed on both sides. The rectangular adjustment box 17 corresponding to the slider 21 has a groove 22 on its side wall. The slider 21 is placed inside the groove 22 and rotates to realize the design of rotating the U-shaped moving plate 20 along the length of the rectangular adjustment box 17.

[0044] In a preferred embodiment of the present invention, a scale line 32 is provided on one side of the top of the rectangular adjustment box 17 for real-time measurement of the moving distance of the U-shaped moving plate 20, so as to provide accurate data control for the subsequent adjustment of the spray radius of the nozzle base 12.

[0045] The operation process of this utility model is as follows: Initial setting: According to the area of ​​the braised meat, the ball screw 19 is driven to rotate by the servo motor 18, which drives the U-shaped moving plate 20 to move along the rectangular adjustment box 17. The scale line 32 displays the moving distance to determine the spray radius of the nozzle base 12.

[0046] Start spraying: The main servo motor 15 drives the rotating disk 16 to rotate, and the U-shaped moving plate 20 synchronously drives the connecting block 23 and the connecting rod 26 to rotate around the center of the meat spraying station 10, and the rotating nozzle 11 performs dynamic spraying.

[0047] Dynamic adjustment: When the connecting rod 26 swings, the sleeve 29 slides along the slide bar 30 to ensure the stable movement of the nozzle base 12.

[0048] Pickling liquid circulation: The pickling liquid tank 13 supplies liquid to the rotating nozzle 11 through the transmission pipe, and the sprayed liquid is guided to the circulation system through the partition tank 14.

[0049] Color protection stage switching: The parameters of color protection agent and brine spraying at different stages, such as initial spray, main spray and final spray, are controlled by solenoid valves.

[0050] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
