Description

Technical Field

[0001] The present application relates to the technical field of food processing equipment, and in particular to a continuous vacuum sugar boiling machine. Background Art

[0002] A sugar boiler is a type of heating and boiling equipment (especially equipment with a secondary heating stage) used to evaporate water from the raw materials, thereby concentrating the sugar solution. Traditional sugar boilers use single- or double-layered kettles (such as a steam boiler) heated by steam or an open flame. The kettle consists of an inner and outer metal body, with a heat source (steam or flame) passing through the middle to indirectly heat the sugar solution. This boiling method in traditional sugar boilers results in slow flow of the sugar solution within the heating chamber or jacketed kettle, leading to significant temperature differences between different areas. Some areas of the sugar solution may burn due to local overheating, while others may suffer from insufficient heating, impacting concentration efficiency. Manual intervention is required from adding ingredients, stirring, to discharging, such as frequent stirring to prevent sticking and manual transfer of the sugar solution, which is inefficient and poses a risk of burns. At high temperatures, the sugar solution easily adheres to the pot walls or stirring mechanism, forming a charred layer. This reduces heat transfer efficiency and increases cleaning complexity, making it difficult to completely remove the adhered material. Summary of the Invention

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0015] See also Figures 1 to 5 As shown, the embodiment of the present application provides a continuous vacuum sugar boiling machine, comprising a frame 10, a boiling device 20, and a vacuum device, wherein: The boiling device 20 includes a tank body 21, a rotor 22, and a drive device 23. The tank body 21 is mounted on top of the frame 10 and is placed horizontally. The tank body 21 has an inlet 211 and an outlet 212 that communicate with the interior of the tank body 21. The inlet 211 and the outlet 212 are located on opposite sides of the tank body 21, with the inlet 211 near the top of the tank body 21 and the outlet 212 at the bottom of the tank body 21.

[0016] The side wall of the tank body 21 has a first interlayer 213 , and the first interlayer 213 is communicated with the steam pipe.

[0017] See also Figure 3 As shown, the rotor 22 is arranged inside the tank body 21, and the two ends of the rotor 22 respectively have a rotating shaft 224. The rotating shafts 224 at both ends of the rotor 22 are rotatably arranged on opposite sides of the tank body 21. The surface of the rotor 22 has a plurality of scrapers 221, and the scrapers 221 are spirally extended along the length direction of the rotor 22. There is a gap between the scrapers 221 and the inner wall of the tank body 21. The driving device 23 is connected to the rotating shaft 224 at one end of the rotor 22, and the vacuum device is connected to the discharge port 212 on the tank body 21.

[0018] See also Figure 1As shown, the driving device 23 includes a high-speed motor 231, a driving wheel 232, a driven wheel 233 and a transmission belt 234; the high-speed motor 231 is set on the frame 10, the driving wheel 232 is connected to the high-speed motor 231, the driven wheel 233 is connected to the rotating shaft 224 at one end of the rotor 22, and the transmission belt 234 is sleeved between the driving wheel 232 and the driven wheel 233.

[0019] During use, the drive device 23 drives the rotor 22 to rotate within the tank body 21. Sugar liquid is continuously added to the tank body 21 through the feed port 211 on the tank body 21. After entering the tank body 21, the spirally extending scraper 221 on the rotating rotor 22 distributes the sugar liquid along the inner wall of the tank body 21 and simultaneously pushes the sugar liquid toward the discharge port 212. A steam pipe continuously circulates hot steam into the first interlayer 213, using the hot steam as a heat source to heat the inner wall of the tank body 21. Simultaneously, a vacuum device continuously removes gas from the tank body 21, creating a negative pressure inside the tank body 21. The sugar liquid in the tank body 21 exchanges heat under negative pressure, lowering its boiling point and allowing the water in the syrup to dissipate more easily. This improves concentration efficiency and enables instant low-temperature boiling. This is particularly important for sugar liquids that require color preservation or dairy products that require nutritional integrity. Lower temperatures prevent the sugar liquid from burning, affecting its color, and damaging the nutritional components of the dairy product.

[0020] In addition, the continuous vacuum sugar boiling machine provided in the embodiment of the present application can continuously process the sugar solution, with high processing efficiency and reduced manual intervention. The rotation of the rotor 22 can stir the sugar solution, so that the sugar solution is heated more evenly.

[0021] See also Figure 3 As shown, in this embodiment of the present application, the rotor 22 is provided with guide plates 222 on its surface, corresponding one-to-one with the scrapers 221. The guide plates 222 are spaced apart and positioned at one end of the guide plates 222 near the discharge port 212. A convergence opening 223 corresponding to the discharge port 212 is formed between the guide plates 222 and the scrapers 221. Both the guide plates 222 and the scrapers 221 are tilted toward the convergence opening 223. The convergence opening 223 formed by the guide plates 222 and the scrapers 221 guides the concentrated sugar solution toward the discharge port 212, preventing accumulation of the sugar solution within the tank 21.

[0022] See also Figure 1 As shown, specifically, the vacuuming device includes a vacuum tank 30, a vacuum pump (not shown in the figure) and a sugar solution delivery pump 40. The vacuum tank 30 is arranged on the frame 10 and is located below the tank body 21. The top of the vacuum tank 30 is connected to the discharge port 212 of the tank body 21 through a pipeline, and the bottom end of the vacuum tank 30 is connected to the sugar solution delivery pump 40. A vacuum port is provided on the top of the vacuum tank, and the vacuum port is connected to the vacuum pump. The vacuum tank 30 continuously maintains a vacuum state.

[0023] See also Figure 4 As shown, the vacuum tank 30 comprises a tank body 31 and a tank lid 32. The tank body 31 has openings at both the top and bottom, and the inner diameter of the tank body 31 gradually decreases from top to bottom. The tank lid 32 covers the top opening of the tank body 31, and the sugar solution delivery pump 40 is connected to the bottom opening of the tank body 31. The sidewall of the tank body 31 has a second interlayer 311, which is connected to a steam pipe. The steam pipe continuously circulates hot steam into the second interlayer 311, using the hot steam as a heat source to heat the tank body 31, thereby maintaining a constant temperature for the sugar solution within the tank body 31, ensuring fluidity and preventing solidification.

[0024] See also Figure 5 As shown, a sugar solution delivery pipe 33 is provided on the tank cover 32. The upper end of the sugar solution delivery pipe 33 is connected to the discharge port 212 of the tank body 21. The lower end of the sugar solution delivery pipe 33 is provided with a sugar solution disperser. The sugar solution disperser includes an outer expansion hopper 34 and an inner conical hopper 35. The inner conical hopper 35 is disposed within the outer expansion hopper 34. The gap between the outer wall of the inner conical hopper 35 and the inner wall of the outer expansion hopper 34 forms a sugar solution dispersion channel. The sugar solution dispersion channel allows the sugar solution to be evenly distributed throughout the vacuum tank 30, ensuring uniform heating.
