Description

Technical Field

[0001] This invention relates to the field of food processing machinery and equipment technology, specifically to a quantitative filling device for braising spices during the braising process of poultry. Background Technology

[0002] Braised meat products, a traditional food enjoyed by many, have seen continuous growth as the food industry, a significant branch of the food sector, has experienced as people's living standards have improved and consumer demands have diversified. The introduction of advanced equipment into the braised meat production field has gradually led to mechanized production, not only satisfying people's pursuit of delicious food but also driving continuous innovation in braised meat production techniques.

[0003] However, the process of stuffing poultry cavities with solid brine ingredients (such as Sichuan peppercorns, chili pepper pieces, and spices) after proper proportioning still presents numerous technical challenges. Traditional methods mainly rely on manual labor or simple stuffing devices, which have the following prominent problems:

[0004] (1) Low standardization: The amount of spices added depends on the operator's experience and lacks precise measurement methods, resulting in poor consistency of saltiness and flavor in the product, which seriously restricts large-scale production.

[0005] (2) Uneven size leads to measurement deviation: Granular spices (such as star anise, chili pieces, Sichuan pepper, etc.) have large size differences. When using traditional measuring cups or plungers for filling, it is easy to cause overfilling or underfilling, and the measurement accuracy is difficult to guarantee.

[0006] (3) Efficiency and waste issues: manual filling is slow, the filling amount depends on experience, the filling error usually exceeds ±5%, the raw material waste is significant, and the production cost remains high.

[0007] (4) Insufficient technical adaptability: General-purpose simple filling equipment has poor compatibility with solid materials in spice, often resulting in blockage or inaccurate metering, and cannot meet the precise filling requirements of granular spices.

[0008] Therefore, there is an urgent need for a high-precision and high-efficiency brine quantitative filling equipment to improve product flavor consistency and production efficiency. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to provide a quantitative filling device for braising broth in the braising process of poultry, which can accurately control the amount of braising broth filled each time, ensure the stability of product flavor, and at the same time greatly improve production efficiency and reduce labor costs and raw material waste.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0011] A quantitative filling device for braising broth in poultry processing includes a lower frame. The bottom of the lower frame is equipped with casters integrating brake pads for moving and fixing the device. An upper frame located at the top of the lower frame is vertically connected to the lower frame via a lifting mechanism for adjusting the device height. The upper frame is equipped with a mixing, dispensing, and leveling mechanism for receiving and mixing pre-proportioned braising broth, dispensing the broth, and leveling the top of the broth. A horizontally movable receiving and dispensing mechanism is located below the mixing, dispensing, and leveling mechanism and can move between a receiving position and a discharging position. The machine includes an adjustable feed container mechanism for receiving and metering the feed from the mixing, feeding, and leveling mechanism; an upper frame also includes a pushing mechanism located below the unloading position of the feed container mechanism for receiving and pushing out the metered feed from the feed container mechanism, and a filling mechanism connected to the pushing mechanism for receiving the metered feed pushed out by the pushing mechanism and filling the metered feed into the poultry cavity; the lifting mechanism, mixing, feeding, and leveling mechanism, feed container mechanism, pushing mechanism, and filling mechanism are electrically connected to a PLC controller mounted on the upper frame.

[0012] Preferably, the bottom of the upper frame and the top of the lower frame are longitudinally slidably assembled, the lifting mechanism is a lifting cylinder disposed between the lower frame and the upper frame, and the bottom of the cylinder body of the lifting cylinder is fixedly connected to the lower frame, the telescopic rod of the lifting cylinder is set upward and fixedly connected to the upper frame; the output end of the PLC controller is connected to the controlled end of the lifting cylinder.

[0013] Preferably, the upper frame is provided with a horizontally arranged support plate, and the support plate has a discharge port located directly above the receiving position of the quantitative container mechanism.

[0014] Preferably, the mixing, feeding, and leveling mechanism includes a mixing cylinder disposed on the upper surface of the support plate for accommodating the proportioned brine, a mixing motor supported above the mixing cylinder, and a mixing, feeding, and leveling device inserted into the mixing cylinder and connected to the mixing motor to rotate under the drive of the mixing motor; the output terminal of the PLC controller is connected to the controlled terminal of the mixing motor.

[0015] The mixing cylinder is a cylindrical body with open top and bottom, and the bottom edge of the mixing cylinder surrounds the discharge port and is located close to the discharge port.

[0016] The mixing and feeding scraper includes a mixing shaft connected to the rotating shaft of the mixing motor and coaxially arranged with the mixing cylinder. Several horizontally extending mixing and feeding scraper blades with a length that can cover the feeding port are evenly arranged circumferentially at the bottom of the mixing shaft. The longitudinal section of the mixing and feeding scraper blade is triangular, including a lower inclined surface that is inclined in the direction of rotation of the mixing and feeding scraper to push the brine downward and feed it through the feeding port when rotating; an upper inclined surface that is connected to the top of the lower inclined surface and is arranged opposite to the lower inclined surface to guide the brine to form a circulating flow during the mixing process; and a side plane that is connected between the ends of the upper and lower inclined surfaces and whose connection end with the lower inclined surface abuts against the upper surface of the support plate to sweep out a precise cylindrical reference surface during the rotation process and scrape the top of the feeding to remove excess brine falling into the top of the metering container mechanism.

[0017] Preferably, the quantitative container mechanism includes a PTFE tray fixedly mounted on the upper frame and located below the discharge port. A groove is formed on the PTFE tray, extending through the PTFE tray from the receiving position to the discharge position. A PTFE plate is provided on the groove, and a receiving cavity is longitudinally opened on the PTFE plate for receiving the material discharged from the discharge port when the bottom is blocked by the groove at the receiving position. The diameter of the receiving cavity is not less than the diameter of the discharge port.

[0018] The side of the PTFE plate away from the unloading position is connected to a horizontally mounted cylinder on the upper frame via a front mounting plate. This cylinder is used to drive the PTFE plate to move horizontally relative to the PTFE support between the receiving position and the unloading position, and to completely detach the bottom of the receiving cavity from the PTFE support after the PTFE plate is in the unloading position, thereby achieving unloading. The output terminal of the PLC controller is connected to the controlled terminal of the unloading cylinder.

[0019] The PTFE plate is provided with a discharge port blocking part on the side of the receiving cavity away from the discharge position, which is used to block the discharge port part when the retraction amount of the telescopic rod of the discharge cylinder is different, so as to realize the adjustable receiving amount; the upper frame is provided with a horizontally threaded top rod that is threaded to the upper frame and abuts against the side of the front plate away from the PTFE plate to realize the quantitative adjustment top rod of the discharge cylinder to limit the retraction amount of the telescopic rod of the discharge cylinder by mechanical limiting.

[0020] Preferably, the pushing mechanism includes a pushing bin horizontally arranged on the upper frame, the top of the pushing bin being connected to a funnel-shaped receiving bin located below the unloading position of the quantitative container mechanism for receiving quantitative brine; one end of the pushing bin has a discharge port, the other end of the pushing bin is closed and connected to a pushing cylinder horizontally arranged on the upper frame, the telescopic rod end of the pushing cylinder passes through the pushing bin and is connected to a pushing block that is sealed and slidably assembled with the inner wall of the pushing bin, for pushing out the quantitative brine falling into the pushing bin from the discharge port under the drive of the pushing cylinder; the output end of the PLC controller is connected to the controlled end of the pushing cylinder.

[0021] Preferably, the filling mechanism includes a material pipe longitudinally arranged at the discharge port end of the feeding hopper, with open top and bottom ends. A feeding groove communicating with the discharge port is provided on the side wall of the material pipe. A longitudinally arranged filling cylinder is provided at the top of the material pipe. The telescopic rod of the filling cylinder is arranged downward and passes through the material pipe and is connected to a nylon push rod that is sealed and slidably assembled with the inner wall of the material pipe. This push rod is used to push out a quantitative amount of brine that enters the material pipe through the feeding groove from the bottom of the material pipe under the drive of the filling cylinder to complete the quantitative filling of brine into the poultry cavity. The bottom of the material pipe is a cone shape that tapers downward to align with the poultry cavity opening. The output end of the PLC controller is connected to the controlled end of the filling cylinder.

[0022] Preferably, the end of the pusher bin with the discharge port is an arc shape that matches the curvature of the side wall of the feed tube so as to connect with the periphery of the feed trough; the side of the pusher block that pushes the quantitative brine is an arc-shaped surface that matches the curvature of the side wall of the feed tube.

[0023] Due to the adoption of the above technical solutions, the technical progress achieved by this invention is as follows.

[0024] This invention achieves ultra-high precision quantitative filling of irregularly shaped solid spices, fundamentally ensuring product flavor consistency:

[0025] The core technology innovatively combines "mechanically adjustable opening area metering" with "absolute reference rotary leveling." Specifically, through a linearly adjustable quantitative adjustment rod, the position of the PTFE plate at the receiving position can be set steplessly and precisely, thereby changing the effective opening area of ​​the discharge port aligned with the receiving cavity. Simultaneously, the unique triangular cross-section design of the stirring and leveling blades creates a precise geometric reference surface during rotation, acting like a precision scraper to forcibly scrape away the accumulated brine above the receiving cavity to the same absolute height each time. The synergistic effect of these two technologies achieves high repeatability of physical quantitative metering, controlling the error of a single filling volume to an extremely low range. This solves the key technical problem of uneven saltiness and flavor in the same batch of products caused by inaccurate manual weighing or simple equipment measurement, laying a solid foundation for large-scale, standardized production.

[0026] This invention significantly improves production efficiency and automation levels, adapting to the needs of large-scale continuous production:

[0027] The equipment achieves fully automated program control through a PLC controller. From mixing and feeding, quantitative receiving and leveling, brine transfer and pushing to final filling, each step is seamless and interconnected, with an operating speed far exceeding that of manual operation. Operators only need to perform simple auxiliary tasks such as feeding, aligning with the poultry cavity, and removing the finished product, significantly reducing labor intensity. This equipment effectively replaces the traditional, inefficient manual filling method. A single machine can form a stable production rhythm and can seamlessly connect to modern food processing production lines, meeting the market's requirements for large-scale, high-efficiency production of braised poultry products.

[0028] This invention is highly versatile and adaptable, and its operation and adjustment are flexible and convenient.

[0029] First, to address the varying filling requirements of different product formulations, the single-use dispensing volume can be quickly and intuitively set simply by turning the quantitative adjustment rod. The adjustment process requires no parts replacement or complex calculations, offering exceptional flexibility. Second, the height of the entire upper frame and working mechanism can be easily adjusted via a lifting cylinder, quickly adapting to the comfortable working area for operators of different heights, demonstrating excellent ergonomic design. Third, its core metering and pushing mechanism is specifically designed for granular, segmented, and other poorly flowing solid spices. The three-dimensional flow field design of the mixing, feeding, and leveling blades effectively prevents material bridging, and the pneumatic pushing method is insensitive to material shape, solving the industry pain points of common filling equipment being prone to clogging and unsuitable for general applications.

[0030] This invention optimizes production hygiene and cost control:

[0031] Automated processes significantly reduce direct contact between the spices and operators, lowering the risk of human contamination. Simultaneously, high-precision metering prevents over- or under-addition of raw materials, directly reducing spice waste. Automated production also reduces reliance on skilled workers, saving labor costs and optimizing the production cost structure from multiple dimensions, including quality improvement, efficiency enhancement, and cost reduction.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] A quantitative filling device for braising broth in the braising process of poultry, combined with Figures 1 to 2As shown, the system includes a lower frame 1, to which an upper frame 2 located at the top is vertically connected via a lifting mechanism, allowing for height adjustment. The upper frame 2 is equipped with a stirring, dispensing, and leveling mechanism 4, a metering container mechanism 5, a pushing mechanism 6, a filling mechanism 7, and a PLC controller. The stirring, dispensing, and leveling mechanism 4 receives the proportioned brine and performs stirring, dispensing, and leveling of the brine. The metering container mechanism 5 is located below the stirring, dispensing, and leveling mechanism 4 and can move horizontally between the receiving and unloading positions. The metering container mechanism 5 receives the brine from the stirring, dispensing, and leveling mechanism 4 and measures the amount of brine dispensed, ensuring stable product flavor. The receiving capacity of the metering container mechanism 5 is adjustable. It can meet the different flavor requirements of the product; the pushing mechanism 6 is located below the unloading position of the quantitative container mechanism 5. The pushing mechanism 6 is used to receive and push out the quantitative brine from the quantitative container mechanism 5; the filling mechanism 7 is connected to the pushing mechanism 6. The filling mechanism 7 is used to receive the quantitative brine pushed out by the pushing mechanism 6 and fill the quantitative brine into the poultry cavity; the PLC controller is electrically connected to the lifting mechanism, the stirring, feeding and leveling mechanism 4, the quantitative container mechanism 5, the pushing mechanism 6 and the filling mechanism 7 respectively, so as to realize the automatic control of the equipment to quantitatively fill the poultry cavity with brine.

[0045] The lower frame 1 forms the base of the equipment, with four casters 11 installed at its bottom. Each caster 11 integrates brake pads, facilitating movement of the equipment within the workshop and securing it in place via the brake pads. The bottom of the upper frame 2 is longitudinally slidably assembled with the top of the lower frame 1. The lifting mechanism is a lifting cylinder 3 positioned between the lower frame 1 and the upper frame 2, with the bottom of the cylinder body fixedly connected to the lower frame 1. The extension rod of the lifting cylinder 3 is upward-facing and fixedly connected to the upper frame 2. The output of the PLC controller is connected to the controlled end of the lifting cylinder 3. Operators, based on their own height, control the extension of the lifting cylinder 3's extension rod via the PLC controller, thereby adjusting the height of the upper frame 2. This allows for height adjustment of all mechanisms on the upper frame 2, enabling operators to quantitatively fill poultry cavities with brine using the equipment.

[0046] like Figure 3 As shown, a horizontally positioned support plate 21 is fixedly installed on the upper frame 2 as a base platform for installing other functional components, and a discharge port 22 is provided on the support plate 21, which is located directly above the receiving position of the quantitative container mechanism 5.

[0047] The mixing, feeding, and leveling mechanism 4 includes a mixing cylinder 41, a mixing motor 42, and a mixing, feeding, and leveling device 43.

[0048] The mixing cylinder 41, used to hold the pre-proportioned brine, is a cylindrical body open at both the top and bottom, vertically fixed to the support plate 21. The bottom edge of the mixing cylinder 41 surrounds and is positioned close to the discharge port 22. The mixing motor 42 is fixed above the mixing cylinder 41 by a bracket, and its rotation shaft is vertically downward and connected to the mixing and feeding scraper 43. The mixing and feeding scraper 43 is inserted into the mixing cylinder 41 and rotates under the drive of the mixing motor 42.

[0049] like Figure 4 As shown, the mixing and feeding scraper 43 includes a mixing shaft 431 coaxially arranged with the mixing cylinder 41, and the top end of the mixing shaft 431 is connected to the rotation shaft of the mixing motor 42. At the bottom of the mixing shaft 431, several horizontally extending mixing and feeding scraper blades 432 are evenly connected in the circumferential direction, and the length of these mixing and feeding scraper blades 432 is sufficient to cover the area of ​​the feeding port 22.

[0050] Each stirring and leveling blade 432 has a triangular longitudinal section, which is key to achieving precise feeding and leveling. This triangular section includes a lower inclined surface 4321, an upper inclined surface 4322, and a side plane 4323. The lower inclined surface 4321 is oriented in the same direction as the rotation of the stirring shaft 431, allowing it to apply a downward force to the brine during rotation, forcing the brine downwards and through the lower feeding port 22 to achieve feeding. The side plane 4323 is a vertical or nearly vertical plane that connects the ends of the upper inclined plane 4322 and the lower inclined plane 4321. The connecting ends of the side plane 4323 and the lower inclined plane 4321 are in close contact with or maintain a very small gap with the upper surface of the bearing plate 21. When the stirring and feeding scraper blade 432 rotates, the connecting ends of the side plane 4323 and the lower inclined plane 4321 sweep out a precise cylindrical reference surface and scrape the top of the feeding material, thereby scraping off the excess brine that falls into the top of the metering container mechanism 5. The bottom end of the upper inclined plane 4322 is connected to the top end of the lower inclined plane 4321, and the upper inclined plane 4322 and the lower inclined plane 4321 are arranged opposite to each other. The upper inclined plane 4322 mainly serves to enhance the structural strength of the stirring and feeding scraper blade 432 and guide the brine to circulate in the stirring cylinder 41 and prevent accumulation.

[0051] The output of the PLC controller is connected to the controlled end of the stirring motor 42. When the operator pours the proportioned mixed brine into the stirring drum 41, the stirring motor 42 is started by the PLC controller, driving the stirring and feeding scraper 43 to rotate. The lower inclined surface 4321 continuously pushes the brine downward, allowing it to fall through the discharge port 22 into the metering container mechanism 5 below. When the metering container mechanism 5 is filled with brine and excess material piles up on top, the side plane 4323 of the continuously rotating stirring and feeding scraper 432, connected to the lower inclined surface 4321, acts like a scraper, precisely scraping away the excess brine that is higher than the reference surface, thus ensuring that the volume of brine falling into the metering container each time is absolutely consistent.

[0052] The quantitative container mechanism 5 is the core of achieving accurate measurement. The quantitative container mechanism 5 includes a PTFE holder 51 fixedly mounted on the upper frame 2 and located below the discharge port 22, such as... Figure 5 As shown, a groove 511 is formed on the PTFE holder 51, and the groove 511 is provided through the PTFE holder 51 along the direction from the receiving position to the unloading position. Figure 6 As shown, a PTFE plate 52 is provided on the tray 511 and is slidably fitted with the tray 511. A receiving cavity 521 is longitudinally opened on the PTFE plate 52. The diameter of the receiving cavity 521 is greater than or equal to the diameter of the discharge port 22. When the PTFE plate 52 is in the receiving position, the receiving cavity 521 is located below the discharge port 22 and the bottom is blocked by the tray 511, forming a top-open "measuring cup" for receiving the brine falling from the discharge port 22.

[0053] A discharge cylinder 53 is connected to the side of the PTFE plate 52 away from the discharge position via a mounting front plate 54. The discharge cylinder 53 is horizontally mounted on the upper frame 2. The discharge cylinder 53 drives the PTFE plate 52 to move horizontally relative to the PTFE support 51 between the receiving position and the discharge position. After the PTFE plate 52 is in the discharge position, the bottom of the receiving cavity 521 is completely disengaged from the PTFE support 51, thereby opening the bottom of the receiving cavity 521 and realizing discharge. At the same time, a clearance opening 512 is provided on the side of the PTFE support 51 away from the discharge position. The clearance opening 512 is used to avoid the mounting front plate 54 to meet the travel range of the PTFE plate 52.

[0054] A discharge port blocking part 522 is integrally formed on the side of the receiving cavity 521 away from the unloading position on the PTFE plate 52. The discharge port blocking part 522 is used to partially block the discharge port 22 when the retraction amount of the telescopic rod of the unloading cylinder 53 is different, thereby realizing the adjustable receiving amount of the receiving cavity 521. A quantitative adjustment rod 55 is horizontally arranged on the upper frame 2. The quantitative adjustment rod 55 is a screw and is threaded to the upper frame 2. The front end of the quantitative adjustment rod 55 is used to abut against the side of the mounting front plate 54 away from the PTFE plate 52. By rotating the quantitative adjustment rod 55, the position of the quantitative adjustment rod 55 can be adjusted, thereby limiting the retraction amount of the telescopic rod of the unloading cylinder 53 by mechanical limiting.

[0055] The output of the PLC controller is connected to the controlled end of the unloading cylinder 53. During use, the capacity is first set via the PLC controller: the quantitative adjustment rod 55 is turned to change its extension length. When the telescopic rod of the unloading cylinder 53 retracts, it pulls the mounting front plate 54 and the PTFE plate 52 backward until the mounting front plate 54 is stopped by the end of the quantitative adjustment rod 55. The position where the PTFE plate 52 stops at this point is its maximum retraction limit. This position determines that the discharge port blocking part 522 on the PTFE plate 52 will block a portion of the discharge port 22 area (when a small capacity is required, the PTFE plate 52 retracts less, the discharge port 22 is blocked more, and the effective discharge area is small; when a large capacity is required, the PTFE plate 52 retracts more, the discharge port 22 is blocked less, and the effective discharge area is large). Since the mixing and feeding scraper 43 continuously feeds material and scrapes the top to a fixed reference surface, the amount of material that can eventually fall into and stay in the receiving chamber 521 is determined by the effective opening area of ​​the unobstructed feeding port 22, thus realizing stepless adjustment of the single filling amount.

[0056] After the settings are completed, the equipment enters the working cycle: the PTFE plate 52 is in the "receiving position". When the receiving cavity 521 receives the material from the discharge port 22 and is scraped flat, the PLC controller controls the discharge cylinder 53 to extend and push the PTFE plate 52 to move horizontally to the "discharge position". At this time, the receiving cavity 521 completely leaves the PTFE support 51 and its bottom is fully open. The metered amount of brine in the receiving cavity 521 falls from the "discharge position" into the pushing mechanism 6 below under the action of gravity.

[0057] like Figures 7 to 9 As shown, the feeding mechanism 6 includes a feeding bin 61 horizontally mounted on the upper frame 2. The top of the feeding bin 61 is connected to a receiving bin 62, which is located below the unloading position of the quantitative container mechanism 5 and is funnel-shaped. The receiving bin 62 is used to receive the quantitative brine falling from the quantitative container mechanism 5. One end of the feeding bin 61 has a discharge port 611, and the other end of the feeding bin 61 is closed by a cylinder fixing plate 65 and connected to a feeding cylinder 63. The feeding cylinder 63 is horizontally mounted on the upper frame 2 by the cylinder fixing plate 65, and the end of the telescopic rod of the feeding cylinder 63 passes through the feeding bin 61 and is connected to a feeding block 64. The feeding block 64 is slidably and sealed to the inner wall of the feeding bin 61. The feeding block 64 is used to push the quantitative brine falling into the feeding bin 61 out of the discharge port 611 under the drive of the feeding cylinder 63.

[0058] The output of the PLC controller is connected to the controlled end of the pusher cylinder 63. When the quantitative brine falls into the receiving bin 62 and enters the pusher bin 61, the PLC controller controls the pusher cylinder 63 to move, pushing the pusher block 64 to move horizontally along the pusher bin 61, thereby neatly pushing the quantitative brine in the pusher bin 61 out of the outlet 611 and into the filling stage.

[0059] The filling mechanism 7 includes a material pipe 71 longitudinally disposed at the discharge port 611 end of the pusher hopper 61, such as... Figure 10 As shown, the top and bottom of the feed pipe 71 are open, and a feed trough 711 communicating with the discharge port 611 is provided on the middle side wall of the feed pipe 71. A longitudinally arranged filling cylinder 72 is installed at the top of the feed pipe 71 via a cylinder fixing flange 73. The telescopic rod of the filling cylinder 72 is positioned downwards and passes through the feed pipe 71, connecting to a nylon push rod. The nylon push rod is slidably and sealingly assembled with the inner wall of the feed pipe 71. Driven by the filling cylinder 72, the nylon push rod pushes out a measured amount of brine that has entered the feed pipe 71 through the feed trough 711 from the bottom of the feed pipe 71, thereby completing the quantitative filling of the poultry cavity with brine. Furthermore, the bottom of the feed pipe 71 is a downwardly tapering cone shape, which facilitates alignment with the poultry cavity opening and thus facilitates the filling of the poultry cavity with brine.

[0060] To optimize the flow of the brine, the feed hopper 61 has an outlet 611 at one end that is arc-shaped to match the curvature of the side wall of the feed pipe 71, and it is easy to connect to the four sides of the feed trough 711; the side of the feed block 64 that pushes the quantitative brine is also designed to be arc-shaped to match the curvature of the side wall of the feed pipe 71.

[0061] The output of the PLC controller is connected to the controlled end of the filling cylinder 72. When the feeding mechanism 6 pushes a fixed amount of brine through the outlet 611 and the feed trough 711 into the middle section of the vertical feed tube 71, the operator holds the poultry cavity and aligns its opening with the bottom of the feed tube 71. Then, the PLC controller starts the filling cylinder 72, driving the nylon push rod to move downward, smoothly and thoroughly pushing the fixed amount of brine temporarily stored in the feed tube 71 into the poultry cavity, completing one filling cycle.

[0062] The overall working principle of this invention is as follows:

[0063] (1) Preparation and height adjustment: The operator moves the equipment to the work position using the casters 11 at the bottom of the lower frame 1 and locks the brake pads to fix it. According to the operator's own height, the operator controls the extension rod of the lifting cylinder 3 to extend and retract through the PLC controller, thereby driving the upper frame 2 and all the mechanisms on it to rise and fall as a whole, so that the bottom outlet of the material tube 71 of the filling mechanism 7 is adjusted to a comfortable height that is easy to align with the poultry cavity.

[0064] (2) Feeding and parameter setting: Pour the pre-mixed solid spices (such as Sichuan peppercorns, chili pepper segments, etc.) into the mixing cylinder 41 fixed on the support plate 21. According to the flavor requirements of the current product, the single feeding amount of the metering container mechanism 5 is set by turning the metering adjustment rod 55. Specifically, rotating the metering adjustment rod 55 changes its front end position. This position will serve as the mechanical limit point when the subsequent unloading cylinder 53 retracts, thereby determining the precise position of the PTFE plate 52 at the receiving position. This position changes the effective opening area of ​​the discharge port 22 aligned with the receiving cavity 521 through the discharge port shielding part 522, thereby determining the amount of material that can be scraped and contained in the receiving cavity 521, i.e., the single feeding amount. After the single feeding amount is set, the stirring motor 42 is started by the PLC controller, driving the stirring discharge scraper 43 to rotate continuously in the mixing cylinder 41 to stir the brine to prevent clumping and prepare for feeding.

[0065] (3) Precise metering and leveling: The PLC controller controls the unloading cylinder 53 to retract, pulling the PTFE plate 52 back to the "receiving position" so that the receiving cavity 521 on it is accurately located below the discharge port 22. At this time, the lower inclined surface 4321 of the continuously rotating stirring discharge scraper 43 continuously pushes the brine downwards, and the brine falls into the receiving cavity 521 below through the discharge port 22, whose effective opening area has been set. The brine does not fill the entire cavity opening in the receiving cavity 521, but gradually accumulates in a local area corresponding to the effective opening area of ​​the discharge port to form a material pile. When the height of the material pile exceeds the upper surface of the support plate 21, the lower edge of the side plane 4323 of the rotating stirring and feeding scraper blade 432 (i.e. the connection end with the lower inclined surface 4321) acts like a precision scraper, scraping away the excess material pile precisely along the upper surface of the support plate 21. This ensures that the amount of brine remaining in the receiving cavity 521 after each scraping is strictly consistent and equal to the predetermined amount determined by the effective opening area of ​​the feeding port.

[0066] (4) Quantitative brine transfer: After accurate measurement and leveling, the PLC controller controls the unloading cylinder 53 to extend and push the PTFE plate 52 to move horizontally to the "unloading position". The receiving cavity 521 is completely removed from the blocking area of ​​the bottom groove 511 of the PTFE tray 51. The bottom of the receiving cavity 521 is fully opened. Under the action of gravity, the quantitative brine in the receiving cavity 521 falls into the receiving bin 62 of the pushing mechanism 6 located directly below it.

[0067] (5) First-stage feeding of brine: A fixed amount of brine is collected in the funnel-shaped receiving bin 62 and enters the horizontally set feeding bin 61. Subsequently, the PLC controller controls the feeding cylinder 63 to drive the feeding block 64 to advance horizontally in the feeding bin 61. The arc-shaped front pushing surface of the feeding block 64 neatly pushes the fixed amount of brine in the bin out through the discharge port 611 at the end of the feeding bin 61.

[0068] (6) Secondary filling of brine: The brine pushed out from the outlet 611 enters the middle section of the vertically set material pipe 71 through the feed chute 711 connected to it for temporary storage. At this time, the operator holds the poultry product and aligns its cavity opening with the bottom of the material pipe 71. Then, the PLC controller starts the filling cylinder 72, driving the nylon push rod to move downward in the material pipe 71, smoothly and thoroughly pushing the measured amount of brine temporarily stored in the material pipe 71 into the poultry cavity, completing a complete filling operation.

[0069] (7) System Reset and Cycle: After one filling is completed, the filling cylinder 72 drives the nylon push rod to retract, the pushing cylinder 63 drives the pushing block 64 to retract, and the unloading cylinder 53 retracts to pull the PTFE plate 52 back to the "receiving position" to prepare for the next receiving. After the operator changes the poultry product to be filled, a new work cycle can begin. The whole process is coordinated by the PLC controller and is carried out automatically and continuously.

[0070] The core innovation of this invention lies in its creative combination of a "mechanically adjustable opening area metering" and an "absolute reference rotary leveling" technology. By quantitatively adjusting the top rod to steplessly set the effective opening area of ​​the feeding port, and utilizing the precise geometric reference formed by the stirring and leveling blades to level the material falling into the fixed-volume receiving chamber, the linear adjustment of the opening area is transformed into precise control of the final material quantity, thus achieving ultra-high precision quantitative measurement of irregularly shaped solid spices. Furthermore, through a pneumatically driven two-stage push, efficient and smooth automated filling is achieved. This equipment fundamentally solves the problems of low efficiency, large errors, and poor product consistency associated with manual filling, significantly improving the standardization, automation level, and production capacity of poultry braised product production.
