Technical Field

[0001] This utility model belongs to the field of food braising technology, specifically a braising device. Background Technology

[0002] As living standards improve, people's demands for material culture are also increasing, including a growing variety of food products. Traditional braised meat products are particularly popular among consumers due to their advantages: rich flavor profiles, achieved through the blending of soy sauce and spices (star anise, cinnamon, Sichuan peppercorns, etc.), resulting in a variety of flavors such as savory, soy sauce, and five-spice, with distinct initial aroma, mouthfeel, and aftertaste that stimulate the appetite; tender and flavorful meat, softened by long-term braising, allowing the braising liquid to fully penetrate, achieving a balance of "salty on the outside and light on the inside," making it suitable for all ages.

[0003] Currently, the braising of food products (braised meat products) is generally carried out using a jacketed kettle. After the braising process is complete, workers manually remove the braising products and then start braising new products. This method of food braising is not only inefficient and labor-intensive, but also allows for small batches of products, making it unsuitable for large-scale production. Utility Model Content

[0004] To address the problems of low efficiency, high labor intensity, and limited capacity for large-scale production caused by traditional manual operation of jacketed kettles in food braising, this invention provides a braising device.

[0005] This utility model is achieved through the following technical solution:

[0006] A braising apparatus includes a hanging conveyor mechanism and a plurality of braising pots. The hanging conveyor mechanism includes a frame and a closed-loop chain. The frame is connected and installed with a lobed guide rail that cooperates with the chain and a drive mechanism that drives the chain. Lifting devices capable of suspending and lifting the braising pots are suspended at intervals on the chain. The apparatus also includes a plurality of heating mechanisms disposed on one side of the frame and capable of heating the plurality of braising pots, and a plurality of tilting mechanisms disposed on the other side of the frame and capable of tilting the plurality of braising pots.

[0007] A further improvement of this utility model is that the bottom side of the braising pot is provided with opposing support shafts; the tilting mechanism includes a base and two opposing support plates disposed on the upper side of the base, and the support plates are provided with a sliding groove that is inclined inward from top to bottom, the sliding groove being used to guide the support shafts.

[0008] A further improvement of this utility model is that the upper opening of the groove is chamfered.

[0009] A further improvement of this utility model is that the base is provided with a support block that can limit and support the upper side of the tilted braising pot.

[0010] A further improvement of this utility model is that the heating mechanism is provided with a limiting ring that can lock and limit the braising pot.

[0011] A further improvement of this utility model is that the lifting device uses an electric hoist, and its lifting end is connected to the edge of the braising pot through several lifting ropes.

[0012] A further improvement of this utility model is that the chain includes several chain links; each chain link includes two oppositely arranged side plates, with a central shaft connected and installed between the two side plates, and a roller rotatably mounted on the central shaft; adjacent chain links are rotated, and the ends of the side plates of adjacent chain links are rotatably connected by a cross-shaped connecting frame; a hanging rod capable of suspending a lifting device is rotatably mounted on the horizontal central shaft of the corresponding chain link; the guide rail has a square cross section, and its inner cavity is in rolling guidance cooperation with the roller of the chain link, and a slot for the hanging rod to pass through is opened in the middle of its bottom surface.

[0013] Further improvements to this utility model include: an open section on the upper side of the guide rail; a drive mechanism including a driving wheel and a driven wheel rotatably mounted on the upper side of the guide rail, with a drag belt fitted on the driving wheel and the driven wheel, and the lower side of the drag belt abutting against a roller standing vertically at the open position; and a motor capable of driving the rotation of the driving wheel is mounted on the frame.

[0014] A further improvement of this utility model is that several brackets are also positioned and installed on the frame inside the drive belt, and an adjusting screw is slidably provided on the bracket. The lower end of the adjusting screw is fixedly connected to a pressure plate that can press down the lower drive belt; and nuts are screwed onto the adjusting screw that can abut against the upper and lower sides of the bracket for tightening.

[0015] A further improvement of this utility model is that the support is provided with a vertical partition.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] In operation, several braising pots suspended at the rear of the frame are filled with braising ingredients and braising liquid. The drive mechanism drives the chain to rotate along the guide rail, thereby moving the rear braising pots with braising liquid to the front of the frame, where they correspond vertically to the heating mechanisms below. The drive mechanism then stops. The lifting device controlling the rear-suspended braising pots lowers the pots, causing them to fall onto the corresponding heating mechanisms. The heating mechanisms then heat the products in the front braising pots, achieving braising. After braising is complete, the lifting device lifts the braising pots, and the drive mechanism operates, moving the braising liquid containing the braising products... The rear of the frame, where all the pots are moved, corresponds vertically to several tilting mechanisms below, and the drive mechanism stops. A lifting device controls the descent of the braising pots containing the braised products. During the descent, the tilting mechanisms tilt the pots (with the opening facing backward). A container is placed beforehand at the tilting opening, and the braised products are completely poured out (into the container). The container can then be removed, and the tilted pots are cleaned internally via water pipes. After cleaning, the lifting device raises the pots back to an upward-facing position, allowing for the next braising cycle. This device enables continuous heating and braising of multiple pots with automatic tilting, significantly improving braising efficiency, reducing manual intervention and labor intensity, greatly increasing the amount of braising per batch, and ensuring product quality stability and consistency. It is fully adaptable to large-scale braising production. Furthermore, the heating and braising area can be separated from the tilting and cleaning area, clearly defining functional areas, improving the smoothness of the production process, and avoiding interference between different processes.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] like Figure 1-7 As shown, this utility model discloses a braising device, including a hanging conveying mechanism 1 and several braising pots 3. The hanging conveying mechanism 1 includes a frame 11 erected vertically in the left-right direction and a closed-loop chain 15. A lobed guide rail 13 that guides and cooperates with the chain 15 and a drive mechanism 14 that drives the chain 15 are fixedly connected and installed on the frame 11. The guide rail 13 surrounds the top of the frame 11 and is connected to the top of the frame 11 through a connecting rod in the front-back direction (horizontal). Lifting devices 2 that can suspend and lift the braising pots 3 are suspended at intervals on the chain 15. This braising device also includes several heating mechanisms 4 located on the front side of the frame 11 and capable of heating several (suspended and falling) braising pots 3, and several tilting mechanisms 5 located on the rear side of the frame 11 and capable of tilting several braising pots 3.

[0029] In use, several braising pots 3 suspended and lifted at the rear of the frame 11 are filled with braising ingredients and braising liquid. The drive mechanism 14 drives the chain 15 to rotate along the guide rail 13, thereby moving the rear braising pots 3 with braising liquid to the front of the frame 11, where they correspond vertically with the lower heating mechanisms 4. The drive mechanism 14 then stops. The lifting device 2 controlling the rear-suspended braising pots 3 lowers the braising pots 3, causing them to fall onto the corresponding heating mechanisms 4. The heating mechanisms 4 heat the products in the front braising pots 3, thus braising them. After braising is complete, the lifting device 2 lifts the braising pots 3, and the drive mechanism 14 operates, moving the braising pots containing the braising liquid... The braising pots 3 containing the prepared products are all moved to the rear of the frame 11, corresponding vertically to several tilting mechanisms 5 below, and the drive mechanism 14 stops. The lifting device 2 controls the braising pots 3 containing the prepared products to fall. During the fall, the tilting mechanisms 5 tilt the braising pots 3 (with the pot opening facing backward). A container is placed at the tilting opening position beforehand, and the prepared products are completely poured out (into the container). Then, the container can be removed, and the inside of the tilted braising pots 3 is cleaned through a water pipe. After cleaning, the lifting device 2 lifts the braising pots 3 to the position with the pot opening facing upward, thus enabling the next cycle of braising operations. This device can realize continuous heating and braising of multiple braising pots 3 and automatic tilting operations, which can greatly improve the product braising efficiency, reduce manual intervention, reduce labor intensity, greatly increase the single braising volume, ensure the stability and consistency of product quality, and is fully adaptable to large-scale braising production. In addition, the heating and braising area can be separated from the pouring and cleaning area, with clear functional zoning, which improves the smoothness of the production process and avoids mutual interference between different processes.

[0030] Among them, different functional areas on the front and rear sides of the frame 11 can be operated simultaneously, that is, the corresponding number of braising pots 3 are suspended on both sides, and the heating and braising operations, as well as the pouring, cleaning, and adding of raw materials are carried out simultaneously, which greatly shortens the braising cycle and improves the braising efficiency.

[0031] Furthermore, the support frame 147 is provided with an upright partition 12. The partition 12 completely separates the different functional areas at the front and back, preventing mutual interference (such as heat diffusion, spillage, etc.), and ensuring the safety, reliability and stability of use; the partition 12 can also improve the structural stability of the frame 11 itself.

[0032] The heating mechanism 4 uses electric heating, such as an induction cooker or resistance heating element. This ensures reliable and stable heating and allows for control of the heating power.

[0033] Furthermore, to prevent sticking, a support frame can be installed on the upper part of the rim of the braising pot 3, and a stirring motor can be installed on the support frame. A stirring paddle that can stir the inside of the braising pot 3 can be installed at the output end of the motor.

[0034] Reference Appendix Figure 1 , 3 4. The upper part of the heating mechanism 4 is equipped with a limiting ring 41 that can lock and limit the braising pot 3. When the braising pot 3 is lowered, the limiting ring 41 can lock and limit the bottom of the braising pot 3 to ensure the accuracy of the heating and placement of the braising pot 3 and ensure reliable heating and braising.

[0035] Reference Appendix Figure 1-4 The lifting device 2 uses an electric hoist, whose lifting end is connected to the rim of the braising pot 3 via four lifting ropes 21. Four lifting rings 31 connected to the lifting ropes 21 are provided on the rim of the braising pot 3. The four lifting rings 31 are symmetrically arranged front-to-back and left-to-right, with the front-to-back distance less than the left-to-right distance (the left-to-right distance is three times the front-to-back distance). The electric hoist has precise lifting control capabilities, enabling it to quickly and stably lift the braising pot 3, meeting the height requirements of the braising pot 3 at different process positions, and improving the operational convenience and efficiency of the braising process. The four lifting ropes 21 connected to the four lifting rings 31 on the rim of the braising pot 3 achieve stable hoisting of the braising pot 3.

[0036] like Figure 6-7 As shown, the chain 15 includes several links 151; each link 151 includes two opposing elongated side plates 1511 (along the length of the chain 15), and a central shaft 1513 is fixedly connected and installed between the two side plates 1511. Two rollers 1514 are rotatably mounted on the central shaft 1513. The two rollers 1514 are arranged close to the two side plates 1511, and a roller gap is formed between the two rollers 1514. The central shaft 1513 can be designed as a stepped shaft shape that is thicker in the middle and thinner at both ends to achieve axial positioning of the rollers 1514. Adjacent links 151 are rotated 90 degrees, that is, the central shaft 1511 of odd-numbered links 151 is rotated 90 degrees. The chain 15 is horizontally positioned, with the central axis 1513 of even-numbered links 151 vertically positioned. The ends of the side plates 1511 of adjacent links 151 are rotatably connected by a cross-shaped connecting frame 1512 (one of the opposite connecting posts of the connecting frame 1512 is rotatably connected to the ends of the two side plates 1511 of a link 151). A hanging rod 152 capable of suspending the lifting device 2 is rotatably mounted on the horizontal central axis 1513 of the corresponding link 151 (between two rollers 1514). The guide rail 13 has a square cross-section, and its inner cavity is rolled and guided by the rollers 1514 of the link 151. A slot for the hanging rod 152 to pass through is opened in the middle of its bottom surface. The square guide rail 13, in conjunction with the unique chain 15 structure, enables the chain 15 to move smoothly, accurately, and steadily along the guide rail 13 (straight section and curved section), reducing chain vibration and jamming during operation. The chain 15 has a simple structure and strong adaptability.

[0037] Furthermore, such as Figure 5As shown, one section of the guide rail 13 is completely open on the upper side (i.e., without a top surface); the drive mechanism 14 includes a drive wheel 143 and a driven wheel 144 rotatably mounted on the upper side of this section of the guide rail 13. The drive wheel 143 and the driven wheel 144 are rotatably mounted on the frame 11 through bearing seats; a drag belt 145 is fitted on the drive wheel 143 and the driven wheel 144, and the lower side of the drag belt 145 rolls against the upper side of the roller 1514 standing vertically at the open position; a motor 141 capable of driving the drive wheel 143 to rotate is installed on the frame 11, and pulleys are installed on both the output shaft of the motor 141 and the rotating shaft of the drive wheel 143, and the two pulleys are connected by a transmission belt 142. The motor 141 provides driving force, which drives the drive wheel 143 to rotate via the transmission belt 142. The drive belt 145 then wraps around the drive wheel 143 and the driven wheel 144, thus realizing the cyclic operation of the drive belt 145. This causes the roller 1514, which is upright at the open position, to roll due to friction, achieving continuous and smooth operation of the chain 15. In addition, the driving method of the drive belt 145 abutting against the roller 1514 has better buffering and overload protection capabilities compared to other direct chain driving methods. When the chain 15 encounters resistance or load changes, the drive belt 145 can buffer the impact through its own elastic deformation, avoiding excessive damage to the motor 141 and the chain 15, and extending the service life of the equipment.

[0038] The drag belt 145 and the roller 1514 standing upright in the open position have a large coefficient of friction, which effectively reduces slippage.

[0039] Furthermore, two front-to-back supports 147 (perpendicular to the direction of the chain 15) are positioned and installed inside the drive belt 145 on the frame 11. An adjusting screw 148 slides vertically through the support 147, and a pressure plate 146 is fixedly connected to the lower end of the adjusting screw 148 to press down the lower drive belt 142. Nuts are screwed onto the adjusting screw 148 to abut and tighten against the upper and lower sides of the support 147. By rotating the adjusting nut, the height of the pressure plate 146 can be flexibly adjusted. The pressure plate 146 presses down on the lower drive belt 145, ensuring reliable contact between the drive belt 145 and the upper part of the vertically positioned roller 1514, effectively preventing slippage during normal power transmission and ensuring the reliability and stability of the chain 15's operation.

[0040] The pressure plate 146 has chamfered edges at both ends (left and right ends) to effectively guide the contact with the roller 1514, avoid jamming, and ensure smooth operation.

[0041] The braising pot 3 has opposing support shafts 32 on its side bottom (aligned with the corresponding chain 15). The tilting mechanism 5 includes a base 51 and two opposing support plates 52 disposed on the upper side of the base 51. The support plates 52 have upper openings and inward (forward) inclined grooves 53 in the direction from top to bottom, which guide the support shafts 32. When tilting is required, the corresponding lifting device 2 lowers the corresponding braising pot 3. The support shafts 32 on both sides of the bottom of the braising pot 3 enter through the top openings of the grooves 53. As the braising pot 3 continues to be lowered, the support shafts 32 are guided downward and inward (towards the frame 11) through the grooves 5, thereby gradually tilting the opening of the braising pot 3 outward until the height of the opening of the braising pot 3 is lower than the height of the bottom, so that the product inside the braising pot 3 can be completely tilted out. This achieves automatic tilting operation, improves tilting efficiency, and saves labor.

[0042] Furthermore, the upper opening of the slide groove 53 is chamfered. This serves to guide the support shaft 32 during insertion, preventing jamming or failure to fit.

[0043] Furthermore, the upper outer side of the base 51 (near the edge) (located between the two support plates 52) is provided with a support block 54 that can limit and support the upper side (near the rim) of the tilted braising pot 3. The top of the support block 54 is provided with an arc-shaped groove that matches the upper side of the braising pot 3. By supporting the rim of the tilted braising pot 3 onto the arc-shaped groove of the support block 54, the stability and safety of the tilting operation are achieved; and the support block 54 can be made of high-temperature resistant rubber material to effectively prevent impact damage to the braising pot 3.

[0044] In use, this braising device involves adding braising ingredients and braising liquid into several braising pots 3 suspended and lifted from the rear of the frame 11. The drive mechanism 14 drives the chain 15 to rotate along the guide rail 13, thereby moving the rear braising pots 3 (containing braising liquid) to the front of the frame 11, where they align vertically with the lower heating mechanisms 4. The drive mechanism 14 then stops. The lifting device 2, controlling the rear-suspended braising pots 3, lowers them, causing them to fall onto the corresponding heating mechanisms 4. Heating by the heating mechanisms 4 then braises the products in the front braising pots 3. After braising is complete, the lifting device 2 lifts the braising pots 3, and the drive mechanism 14 operates, moving the containers... The rear of the frame 11, containing all the braised products in the braising pots 3, is moved and corresponds vertically to several tilting mechanisms 5 below. The drive mechanism 14 stops. The lifting device 2 controls the braising pots 3 containing the braised products to fall. During the fall, the tilting mechanisms 5 tilt the braising pots 3 (with the pot opening facing backward). A container is placed at the tilting opening position beforehand, and the braised products are completely poured out (into the container). Then, the container can be removed, and the inside of the tilted braising pots 3 can be cleaned through a water pipe. After cleaning, the lifting device 2 lifts the braising pots 3 back to the upward position, thus enabling the next cycle of braising. This device can realize continuous heating and braising of multiple braising pots 3 and automatic tilting operations, which can greatly improve the braising efficiency, reduce manual intervention, reduce labor intensity, greatly increase the single braising volume, ensure the stability and consistency of product quality, and is fully adaptable to large-scale braising production. In addition, the heating and braising area can be separated from the pouring and cleaning area, with clear functional zoning, which improves the smoothness of the production process and avoids mutual interference between different processes.
