The syrup production process requires stirring to achieve the desired concentration. Syrup is typically prepared by mixing sugar granules with the solution. Boiling sugar is a complex process requiring different temperature settings at different times, and each boil takes several minutes. Currently, single-pot boiling is commonly used, resulting in long boiling times and low production efficiency. Utility Model Content

A heating device for the pot is set below each stirring device. When cooking the syrup, the same cooking time is set in each pot, that is, the cooking time of a single pot is evenly distributed among the pots corresponding to multiple stirring devices, that is, the pots corresponding to multiple stirring devices are cooked simultaneously. Thus, the syrup in one pot is cooked through multiple heating devices, and the cooking efficiency is multiplied. At the same time, all stirring devices are set on the same lifting device, which realizes efficient and synchronous lifting of the stirring devices, further ensuring the reliability of the cooking process.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the lifting device includes a mounting plate, a gear and rack lifting mechanism, and a lifting drive motor; the gear and rack lifting mechanism includes a gear mechanism and a rack mechanism, the lifting drive motor drives the gear mechanism, the rack mechanism is fixedly connected to the mounting plate, and the mounting plate is fixedly connected to multiple stirring devices.

[0008] The beneficial effects of adopting the above-mentioned further solutions are that the gear and rack jack has better transmission efficiency and higher reliability.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the gear and rack lift includes two, located at both ends of the mounting plate, and the two gear mechanisms are fixedly connected by a connecting shaft.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the stirring device includes a transmission mechanism and stirring blades. The stirring blades include a rotating shaft and blades. The blades are used to contact the pot body and stir the syrup. One end of the rotating shaft is fixedly connected to the stirring blades, and the other end of the rotating shaft passes through a structural fixing block and is fixedly connected to the transmission mechanism. The rotating shaft is rotatably connected to the structural fixing block, and the structural fixing block is fixedly connected to the mounting plate. Adjacent transmission mechanisms are connected by chain drive.

[0014] The advantages of adopting the above-mentioned further solution are: by connecting the transmission mechanisms on multiple stirring devices to each other through chain transmission, a single drive source can drive multiple stirring devices simultaneously, resulting in a simple structure and saving costs and space.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, the rotating shaft can slide in the vertical direction of the structural fixing block, and an elastic component that drives the rotating shaft to move downward is sleeved below the structural fixing block.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting an elastic component that drives the rotating shaft to move downward, the stirring teeth of the stirring blade can be fully pressed against the bottom of the stirring container, ensuring that no material sticks to the bottom, and further preventing the bottom material from burning when there is a heating system.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, the blade has a rotating shaft connection end and a stirring end. The stirring end is provided with stirring teeth and contacts the bottom of the container. The gap between adjacent stirring teeth is a tooth gap. The width of the stirring teeth is greater than the width of the tooth gap. The rotating shaft is fixedly connected to the rotating shaft connection end. The axis of the rotating shaft is located on the stirring teeth and close to the tooth gap. When the blade rotates around the axis, the stirring teeth on one side of the axis cover the tooth gap on the other side.

[0020] The beneficial effects of adopting the above-mentioned further solution are as follows: the stirring end is provided with stirring teeth and contacts the bottom of the container, so that the stirring teeth can stir the sugar particles at the bottom of the container, and there will be no sugar particles remaining at the bottom of the container; furthermore, the stirring end is set in a tooth shape, so that when the blade rotates around the axis, the stirring teeth on one side of the axis cover the tooth gaps on the other side. That is, during stirring, the tooth gaps between two adjacent stirring teeth are used for mixing of syrup, ensuring that the sugar particles are fully mixed and dissolved with the solution, and improving the uniformity of syrup mixing.

[0021] Based on the above technical solution, the present invention can be further improved as follows.

[0022] Furthermore, the side of the stirring teeth is provided with a flow guiding structure.

[0024] Based on the above technical solution, the present invention can be further improved as follows.

[0025] Furthermore, the bottom of the stirring teeth is provided with an anti-crystallization structure.

[0026] The beneficial effect of adopting the above-mentioned further solution is that by setting an anti-crystallization structure, syrup deposition and burning at the bottom of the container can be further avoided.

[0027] Based on the above technical solution, the present invention can be further improved as follows.

[0028] Furthermore, multiple stirring teeth are independently arranged and distributed at equal circumferential angles in a direction perpendicular to the axis.

[0029] The beneficial effects of adopting the above-mentioned further scheme are: the equal circumferential angle distribution, that is, the equal phase difference distribution of the stirring teeth, causes the vortices generated by adjacent stirring teeth to be misaligned in the time-space dimension, forming a continuous asymmetric shear field, which improves the shear uniformity of the stirring teeth on the syrup and enhances the efficiency.

Detailed Implementation

[0041] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0042] See the structural schematic diagram of the sugar boiling system of this utility model. Figures 1 to 3The system includes a stirring system and a pot body 3. The stirring system includes a lifting device and multiple stirring devices, which are located below the lifting device. The pot body 3 is movably located below the stirring devices. The lifting device includes a mounting plate 14, a gear and rack lifting mechanism, and a lifting drive motor 11. The gear and rack lifting mechanism includes a gear mechanism 12 and a rack mechanism 13. The lifting drive motor 11 drives the gear mechanism 12, and the rack mechanism 13 is fixedly connected to the mounting plate 14. The mounting plate 14 is fixedly connected to multiple stirring devices. There are two gear and rack lifting mechanisms, located at both ends of the mounting plate, and the two gear mechanisms 12 are fixedly connected by a connecting shaft 15.

[0043] Specifically, the entire lifting device is fixed on the frame 5. The rack and pinion lift is fitted onto the bushings 16. The two bushings 16 are fixedly connected to the frame 5 via two support plates 4. The gear mechanism 12 is a gear shaft that passes horizontally through the bushing 16, and the rack mechanism 13 is a rack shaft that passes vertically through the bushing 16. The gear shaft and rack shaft form a meshing transmission structure at the bushing 16, and the two gear shafts are fixedly connected via a connecting shaft 15. A lifting drive motor 11 is provided on the left side, and the output shaft of the lifting drive motor 11 is connected to the gear shaft on the left side. Mounting plates 14 are fixedly connected to the ends of the two rack shafts away from the bushings 16.

[0044] In this embodiment, seven stirring devices are evenly distributed on the mounting plate 14, and seven heating devices (not shown in the figure) are also provided, fixedly installed below the stirring devices at corresponding positions. Each stirring device includes a transmission mechanism 22 and stirring blades. The stirring blades include a rotating shaft 23 and blades. The blades are used to contact the pot body 3 and stir the syrup. One end of the rotating shaft 23 is fixedly connected to the stirring blades, and the other end of the rotating shaft 23 passes through a structural fixing block 28 and is fixedly connected to the transmission mechanism 22. The rotating shaft 23 is rotatably connected to the structural fixing block 28, which is fixedly connected to the mounting plate 14. Adjacent transmission mechanisms 22 are connected via chains 29. The stirring drive motor 21 is located on the left side of the mounting plate 14, and its output shaft is directly connected to the rotating shaft 23 of the first stirring device on the left. Figure 1 As shown, since the rotating shaft 23 is fixedly connected to the transmission mechanism 22, the rotating shaft 23 drives the first transmission mechanism 22 on the left to rotate. The first transmission mechanism 22 transmits power to the second stirring device through the chain 29, and so on, driving all seven stirring devices to work. In a specific embodiment, each stirring device can be set with a different stirring speed as needed, and the size of each transmission mechanism 22 can be adjusted to achieve the required speed.

[0045] In this embodiment, the sugar-cooking system contains syrup in seven pots 3. For example, according to the settings, the stirring time for each pot 3 is 40 seconds. When the pot 3 is directly below the stirring device, the lifting drive motor 11 is started, driving all seven stirring devices to descend. According to the settings, the driving stops when the blades of the stirring device touch the bottom of the pot 3. Then, the stirring drive motor 21 stirs the syrup in the pot 3 and heats it through the heating device. When the stirring time reaches the set 40 seconds, the lifting drive motor 11 is started, driving all seven stirring devices to rise. Then, the pot 3 moves one position to the right, that is, each pot 3 enters the next position for heating and stirring, and is heated through the corresponding heating device. After completing the cooking at the last position, the entire syrup cooking is completed. The seven heating and stirring stations in this embodiment allow for the completion of one batch of syrup cooking in 40 seconds. This means that a batch of cooked syrup can be produced every 40 seconds at the last station, a seven-fold increase in efficiency compared to the 280-second cooking time required for a single batch. Simultaneously, the simultaneous lifting and lowering of the seven stirring devices improves the consistency and stability of continuous sugar cooking. It should be noted that the pot bodies 3 can be positioned on the chain drive mechanism as needed, with the number of pot bodies 3 covering the entire chain drive mechanism to ensure the continuity of the sugar cooking process. Furthermore, users can set different cooking temperature parameters for each stirring device's corresponding pot body according to actual sugar cooking requirements to achieve the optimal cooking effect; the heating devices can be selected using conventional methods such as direct heating or electromagnetic heating.

[0046] See the schematic diagram of the assembly structure between the stirring device and the pot body 3. Figure 4 The stirring device includes a transmission mechanism 22 and stirring blades. The transmission mechanism 22 includes a transmission sprocket. A rotating shaft 23 passes through a structural fixing block 28 and is fixedly connected to the transmission sprocket. The rotating shaft 23 is rotatably connected to the structural fixing block 28. The structural fixing block 28 is fixedly mounted on the mounting plate 14. The rotating shaft 23 can slide vertically on the structural fixing block 28. An elastic component 27 for driving the rotating shaft 23 to move downward is sleeved below the structural fixing block 28. Specifically, the structural fixing block 28 is configured with a through hole structure in the vertical direction, and the rotating shaft 23 can freely rotate and slide up and down in the through hole structure. In this embodiment, the elastic component 27 is a spring. The spring is set at the lower part of the rotating shaft 23. One stop block abuts against the structural fixing block 28, and another stop block is sleeved at the lower part of the rotating shaft 23. The two ends of the spring abut against the two stop blocks respectively.

[0047] The stirring blade includes a rotating shaft 23 and blades. Each blade has a rotating shaft connection end 24 and a stirring end. The stirring end has stirring teeth 25 that contact the bottom of the container. The gap between adjacent stirring teeth 25 is a tooth gap 26. The width of the stirring teeth 25 is greater than the width of the tooth gap 26. The rotating shaft 23 is fixedly connected to the rotating shaft connection end 24. The axis of the rotating shaft 23 is located on the stirring teeth 25 and near the tooth gap 26. When the blade rotates around the axis, the stirring teeth 25 on one side of the axis cover the tooth gap 26 on the other side. In this embodiment, there are 5 stirring teeth 25 and 4 tooth gaps 26. The stirring teeth 25, counted from right to left, are designated as the first stirring tooth 25, the second stirring tooth 25, the third stirring tooth 25, and so on. The tooth gaps 26, counted from right to left, are designated as the first tooth gap 26, the second tooth gap 26, the third tooth gap 26, and the fourth tooth gap 26. The axis of the rotating shaft 23 is located on the third stirring tooth 25 and near the left edge of the third stirring tooth 25. When the blade rotates around the rotating shaft 23, the first stirring tooth 25 covers the area outside the fifth stirring tooth 25, the second stirring tooth 25 covers the area of ​​the fourth tooth cavity 26, the third stirring tooth 25 covers the area of ​​the third tooth cavity 26, the fourth stirring tooth 25 covers the area of ​​the second tooth cavity 26, and the fifth stirring tooth 25 covers the area of ​​the first tooth cavity 26.

[0048] The working process of the stirring device in this embodiment is as follows: the power drives the sprocket to rotate, the sprocket drives the rotating shaft 23 to rotate and drives the blades to rotate. During the rotation, when the blades rotate around the axis of the rotating shaft 23, the stirring teeth 25 on one side of the axis cover the tooth gaps 26 on the other side. That is, during stirring, the tooth gaps 26 between two adjacent stirring teeth 25 are used for mixing the syrup, ensuring that the sugar particles and the solution are fully mixed and dissolved, thus improving the uniformity of the syrup mixture. At the same time, the spring generates a downward thrust on the rotating shaft 23, ensuring that the stirring teeth 25 are in full contact with the bottom of the container. In this way, the stirring teeth 25 can stir the sugar particles at the bottom of the container, and there will be no sugar particles remaining at the bottom of the container, ensuring that no material sticks to the bottom, and further preventing the bottom material from burning in the case of a heating system.

[0049] See the structural diagram of the blade in Example 1. Figure 5 and Figure 6 That is, there are 5 stirring teeth 25 and 4 toothed openings 26, and the stirring teeth 25 are rectangular.

[0050] In a specific embodiment, the side of the stirring tooth 25 is provided with a flow guiding structure, which can further avoid local deposition and make the temperature of the syrup in the container more uniform.

[0051] Figure 7 This is a schematic diagram showing that the stirring teeth 25 have a flow guiding structure on their side. That is, from the top view, the stirring teeth 25 are provided with arc-shaped boss structures on both sides.

[0052] In a specific embodiment, the bottom of the stirring teeth 25 is provided with an anti-crystallization structure to prevent syrup from depositing and burning at the bottom of the container. The anti-crystallization structure is a microgroove array, such as... Figure 8 The anti-crystallization structure shown features microgrooves spirally distributed radially along the blade; the microgrooves are 0.5-1 mm deep, 0.1-0.3 mm wide, and spaced 1.5-2.5 mm apart. This spiral distribution of microgrooves induces secondary eddies, breaking the laminar boundary layer of the syrup, enhancing micro-shear, and forcibly dispersing and shearing unmelted sugar particles, thus preventing scorching at the bottom of the container. Furthermore, it improves the effective diffusion coefficient of the syrup, ensuring uniform mixing and reducing the deposition rate of coking deposits.

[0053] Figure 9 This is a bottom view of the blade embodiment four. In this embodiment, five stirring teeth 25 are still provided. These five stirring teeth 25 are independently arranged. From the bottom view, it can be seen that they are evenly distributed in the direction perpendicular to the axis, meaning the circumferential angle between two adjacent stirring teeth 25 is 72°, which is also the phase difference between two adjacent stirring teeth 25 is 72°. The tooth gap 26 formed by two adjacent stirring teeth 25 in the radial direction. In this embodiment, the vortices generated by adjacent stirring teeth 25 during stirring are misaligned in the time-space dimension, forming a continuous asymmetric shear field. This improves the shear uniformity of the syrup by the stirring teeth 25, thus increasing efficiency. Figure 9 As shown in the diagram, the rightmost stirring tooth 25 is the first stirring tooth, and counting clockwise, they are the second to the fifth stirring teeth.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
