Description

Technical Field

[0001] This utility model relates to the field of sugar boiling container technology, and in particular to a bottom-partitioned heating sugar boiling container. Background Technology

[0002] Sugar boiling technology is widely used in various food and traditional Chinese medicine fields such as candy making, medicinal food processing, and seasoning preparation. This process usually involves continuously heating and stirring a high-concentration sugar solution until it reaches a preset viscosity, color, or odor. However, because the viscosity of the sugar solution changes drastically during heating and is prone to scorching, the heating control method directly affects the quality and efficiency of sugar boiling.

[0003] In traditional sugar-boiling equipment, the bottom of the container typically employs a single, integrated heating structure, meaning that a single heat source uniformly heats the entire bottom surface of the container. While this heating method is simple in structure, it has the following drawbacks: Firstly, uneven heat convection and rapid cooling at the edges during the sugar boiling process can lead to localized overheating or excessive temperature differences, affecting the quality of the sugar syrup. Secondly, the integrated heating mode makes it difficult to regionally adjust the heat requirements of the sugar syrup at different stages of boiling, lacking flexibility. Therefore, to address these issues, the concept of "bottom-zoned heating" has emerged in recent years as an improvement to the heating structure.

[0004] Bottom-zone heating typically refers to dividing the bottom of the sugar-cooking container into two or more heating zones. Each heating zone is equipped with an independent heating unit, such as an electric heating element, an electric heating tube, or an electromagnetic heating module. Each zone can achieve differentiated heating intensity adjustment through independent control circuits, timing logic, or temperature control systems. The main advantage of this structure is that it can flexibly adjust the working state of each heating zone according to the sugar solution distribution, heat convection pattern, or the needs of the process stage, thereby improving heating uniformity and cooking efficiency, and effectively preventing local scorching or sugar solution splashing.

[0005] However, despite the relatively mature design of bottom-zone heating structures, users still cannot accurately and timely obtain the viscosity of the sugar syrup during the cooking process in existing sugar-boiling equipment. Since the viscosity of the sugar syrup is often closely related to heating time, temperature, and water content, if the viscosity change trend cannot be grasped in time, the operator needs to rely on experience to judge the heat, which has a large error and can easily lead to problems such as the sugar syrup not being cooked through, overcooking, or even caramelizing.

[0006] Furthermore, we disclose a bottom-partitioned heating sugar-cooking container to meet the practical needs of existing technologies that cannot obtain the syrup viscosity status in a timely manner, resulting in inaccurate control of the sugar-cooking process. Utility Model Content

[0010] Preferably, a sealing sleeve is provided between the rotating rod and the connecting rod.

A fixing rod is fixedly connected to one side of the outer wall of the sealing sleeve. The end of the fixing rod away from the sealing sleeve is fixedly connected to the inner wall of the sugar boiling tank. A limit rod is engaged and rotatably connected to the middle of the upper end of the connecting gear. The upper end of the limit rod passes through the gap between the connecting rod and the rotating rod and is fixedly connected to the inner wall of the sealing sleeve.

[0011] Preferably, the triggering structure includes a rotating plate, the lower end of the connecting rod is hollow, the rotating plate is disposed inside the lower end of the connecting rod, and the diameter of the rotating plate is the same as the inner diameter of the connecting rod. Movable grooves are formed on both sides of the lower end of the outer wall of the connecting rod at the height of the rotating plate. Connectors are fixedly connected to both sides of the outer wall of the rotating plate, and both connectors are slidably connected to the movable grooves. Sealing and telescopic layers are fixedly connected to both sides of the connectors. The ends of the two sealing and telescopic layers away from the connectors are fixedly connected to the inner sidewalls of both ends of the movable grooves. A resisting spring is fixedly connected to one end face of the connector, and the end of the resisting spring away from the connector is fixedly connected to the inner sidewall of one side of the movable groove. The resisting spring is located between the sealing and telescopic layers and the rotating plate.

[0012] Preferably, the end of the connector away from the rotating plate is fixedly connected to the scraper, and a connecting shaft is fixedly connected to the lower end of the rotating plate, with the lower end of the connecting shaft penetrating the sugar boiling pot.

[0013] Preferably, the viscosity display component includes a winding disc that is rotatably connected to the lower middle part of the sugar boiling tank, the lower end of the connecting shaft is fixedly connected to the winding disc, a steel wire rope is fixedly connected to the outer wall of the winding disc, a fixing block is fixedly connected to one side of the lower middle part of the sugar boiling tank, and the steel wire rope passes through the fixing block and is slidably connected to the fixing block.

[0014] Preferably, the viscosity display component further includes a display panel fixedly connected to the lower end of the middle of one side face of the sugar boiling tank.

[0017] The beneficial effects of this utility model are: This bottom-partitioned heating sugar-boiling container achieves real-time feedback on the viscosity of the syrup during the boiling process through mechanical transmission between the internal scraper obstruction structure and the display component below. Through the linkage of components such as the rotating plate, connecting shaft, winding disc, and steel wire rope, the viscosity change is converted into the displacement of the sliding plate in the transparent display plate, thereby realizing the intuitive display of the viscosity value. It has a simple structure, strong stability, and is particularly suitable for environments such as high temperature and high humidity that are not conducive to the use of electronic components.

[0018] This bottom-partitioned heating sugar-boiling container features a speed reduction transmission structure at the lower end of the rotating rod, connecting the rod to the scraper. This allows the scraper to rotate continuously at low speed, scraping against the bottom of the sugar-boiling tank.

It also improves the uniformity of sugar syrup heating and enhances the quality of the boiled sugar.

[0019] This bottom-partitioned heating sugar-boiling container features a viscosity display system with a transparent display panel and scale lines. The movement of the internal sliding plate directly reflects the changes in the sugar solution's viscosity, allowing operators to judge the boiling status without additional tools. Furthermore, the system is entirely based on mechanical linkage principles, requiring no maintenance other than normal lubrication, making it suitable for various industrial environments.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0025] like Figures 1 to 5 As shown, a bottom-zone heating sugar-cooking container includes a sugar-cooking pot 1, which is a hollow sealed structure. Multiple independently controlled electric heating elements are installed at the bottom of the pot. The structure of the electric heating elements is not shown and is existing technology. The heating elements are used to achieve zone heating of the bottom area of ​​the sugar-cooking pot 1. The inside of the sugar-cooking pot 1 is used to hold the syrup raw materials and to heat and cook them.

[0026] A servo motor 2 is fixedly installed at the middle of the upper end of the sugar boiling tank 1. The output end of the servo motor 2 is fixedly connected to the rotating rod 6 in the middle, which is used to drive the rotating rod 6 to rotate at high speed. The rotating rod 6 passes through the top of the sugar boiling tank 1 and is set in the vertical direction. Multiple stirring rods 7 are fixedly connected to both sides of its outer wall in the radial direction. The stirring rods 7 rotate around the central axis under the drive of the motor, which is used to continuously stir the sugar liquid in the tank, improve the heating uniformity and prevent scorching.

[0027] A drive gear 20 is fixedly installed at the lower end of the rotating rod 6, and a connecting gear 18 is meshed on one side of it. The connecting gear 18 is then meshed with the internal gear ring 17 at the upper end of the connecting rod 10 to form a transmission structure. In this structure, the servo motor 2 drives the rotating rod 6 to rotate at high speed. Through the gear transmission mentioned above, the connecting rod 10 rotates slowly and synchronously at a speed lower than that of the rotating rod 6.

[0028] The connecting rod 10 is a hollow cylindrical structure, installed inside the sugar boiling tank 1, and arranged coaxially with the rotating rod 6. Scrapers 11 are connected to both sides of the connecting rod 10. The scrapers 11 are used to rotate and scrape the inner wall of the bottom of the sugar boiling tank 1 to prevent the sugar liquid from scorching or remaining at the bottom of the tank. To achieve sealing and support, a sealing sleeve 9 is fitted on the outside of the rotating rod 6 and the connecting rod 10. The upper and lower inner walls of the sealing sleeve 9 are respectively engaged and rotatably connected to the rotating rod 6 and the connecting rod 10. A fixing rod 8 is fixedly connected to one side of its outer wall. The end of the fixing rod 8 away from the sealing sleeve 9 is fixedly connected to the inner wall of the sugar boiling tank 1 to limit the rotation of the sealing structure. To prevent the connecting gear 18 from dislodging, a limiting rod 19 is engaged and connected to the upper end of the connecting gear 18. The limiting rod 19 passes through the gap between the rotating rod 6 and the connecting rod 10 and is fixedly connected to the sealing sleeve 9.

[0029] Furthermore, the lower end of the connecting rod 10 is hollow, forming an inner cavity in which a rotating plate 16 is installed. The diameter of the rotating plate 16 is basically the same as the inner diameter of the connecting rod 10, allowing it to rotate stably within it. Two connecting pieces 25 are fixedly connected to the outer edges of both sides of the rotating plate 16. The connecting pieces 25 are slidably connected to the movable grooves 21 opened on both sides of the lower outer wall of the connecting rod 10, forming a sliding constraint structure. Sealing expansion layers 23 are fixedly connected to both sides of the connecting pieces 25 for buffering and sealing. The distal ends of the sealing expansion layers 23 are fixedly connected to the inner walls of both ends of the movable grooves 21, thereby ensuring the airtightness and flexibility of the rotating plate 16 during transmission. A resisting spring 22 is also fixedly connected to one end face of the connecting piece 25. The end of the resisting spring 22 away from the connecting piece 25 is fixedly connected to one side of the inner wall of the movable groove 21, playing a buffering role. The end of the connecting piece 25 away from the rotating plate 16 is fixedly connected to the scraper 11, thereby forming an integrated linkage mechanism from the scraper 11 to the rotating plate 16.

[0030] A connecting shaft 15 is fixedly connected to the lower end of the rotating plate 16. The connecting shaft 15 passes through the bottom of the sugar boiling tank 1, and its lower end is fixedly connected to the winding disc 12 located in the middle of the bottom of the tank. The winding disc 12 can rotate around the axis. A steel wire rope 5 is wound around its outer wall. The steel wire rope 5 is led out from the winding disc 12 and passes through the fixing block 14 located on one side of the middle of the bottom of the sugar boiling tank 1. It is fixedly connected to the sliding plate 13 in the display plate 4 installed at the lower side of the sugar boiling tank 1. The display plate 4 is a hollow structure made of transparent resin. Its front end face is provided with longitudinal scale lines for providing visual reading of the viscosity state. The bottom of the display plate 4 is an open structure, and the sliding plate 13 can slide up and down inside it.

[0031] To achieve stable status display and automatic reset, a reset spring 24 is fixedly connected to the lower end of the sliding plate 13. The spring is sleeved on the outside of the wire rope 5, and its lower end is fixedly connected to the bottom inner wall of the display plate 4. It is used to push the sliding plate 13 to reset after the tension of the wire rope 5 is released.

[0032] In actual operation, the servo motor 2 drives the rotating rod 6 to rotate at high speed, the stirring rod 7 mixes the sugar liquid in the tank, and at the same time drives the connecting rod 10 to rotate at low speed through the transmission structure, thereby driving the scraper 11 to stick to the bottom inner wall of the sugar boiling tank 1 for scraping.

[0033] When the syrup viscosity is low, the scraper 11 rotates easily, the rotating plate 16 drives smoothly, and the connecting shaft 15 and the winding disc 12 rotate at a small angle, resulting in a small sliding range of the sliding plate 13 in the display plate 4. When the syrup viscosity increases, the scraper 11 experiences increased resistance during rotation, causing the connecting piece 25 to transmit the rotational resistance to the rotating plate 16 through the compression process of the contact spring 22. This further drives the connecting shaft 15 to increase its rotation angle, and the winding disc 12 winds more steel wire rope 5, pulling the sliding plate 13 upward in the display plate 4. The operator can read the viscosity status through the scale lines to help judge the sugar boiling process. The reset spring 24 pushes the sliding plate 13 back to its original position when the resistance decreases, ensuring the dynamic and continuous nature of the detection feedback.

[0034] In addition, the sugar boiling tank 1 is equipped with a feed pipe 3 on one side of the upper end and a discharge pipe on one side of the lower end for material loading and unloading, which facilitates continuous operation.

[0035] This implementation method uses the principle of structural linkage to realize sensorless detection and mechanical visual display of syrup viscosity during the sugar boiling process. It does not require electronic circuits or sensor components and has the characteristics of simple structure, stable operation, and suitability for use in high-temperature environments. It is especially suitable for viscosity-sensitive processes, such as the boiling control of maltose and candied sugar.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
