[0002] In the food processing industry, especially the sugar industry, evaporation and concentration of sugarcane syrup is a key step in the production process. Traditional evaporation and concentration methods usually use single-stage or multi-stage evaporators to evaporate water by heating, thereby increasing the concentration of the syrup. However, the traditional concentration process has some problems:

[0003] The internal structure of traditional equipment is complex, making cleaning and maintenance inconvenient, which easily leads to material residue, increasing the difficulty of cleaning and downtime; many existing evaporation and concentration systems rely on manual operation and lack efficient automated control systems, making it difficult to achieve continuous and stable large-scale production; the lack of vacuum control in evaporation and concentration leads to excessive bubbles in the syrup raw materials, affecting product quality.

[0004] To this end, we provide a multi-stage evaporation and concentration sugarcane syrup equipment to solve the above problems. Utility Model Content

[0031] The buffer tank 300 includes a buffer base 301, a gas tank 302 fixed to the upper portion of the buffer base 301, and a sealing cover 303 sealed at the upper opening of the gas tank 302;

[0032] The vacuum assembly 400 includes a pump body 401 connected to the buffer base 301 via an air pipe, an exhaust pipe 405 connected to the exhaust end of the pump body 401, an exhaust valve 404 arranged on the side of the exhaust pipe 405, and a pressure gauge 403 matched with the exhaust pipe 405. The exhaust pipe 405 is provided with a fixing part 402 on the outside, and the fixing part 402 is fixed to the side of the gas tank 302.

[0033] Specifically, a pipeline assembly 200 is provided between adjacent evaporation tanks 100 and between the evaporation tank 100 and the buffer tank 300, and the pipeline assembly 200 includes:

[0034] The control valve 201 is fixed to the sides of the annular support base 101 and the buffer base 301, and is connected to the tank body 102 and the bottom of the gas tank 302 through a connecting pipe;

[0035] The delivery pipe 202 is connected to the control valve 201 at one end and passes through the upper part of the tank body 102 at the other end. The end of the delivery pipe 202 is located at the bottom of the tank body 102 and is provided with a trumpet-shaped opening.

[0036] Furthermore, a bottom plate 500 is fixed to the bottom circumference of the annular support base 101 and the buffer base 301 via connecting parts, and the bottom plate 500 is fixed to the outer support surface via connecting parts; a heater 600 is embedded in the annular support base 101, and the heater 600 is in contact with the bottom of the tank body 102, and a conical filter layer is provided at the bottom of the tank body 102.

[0037] The multi-stage evaporation and concentration equipment for sugarcane syrup proposed in this technical solution effectively realizes continuous or batch syrup concentration operation. The use of multi-stage evaporation can further improve energy utilization efficiency and reduce energy consumption. Further explanations of this technical solution are as follows:

[0038] In the evaporator 100, the annular support base 101 provides stable support, the built-in heater 600 is used to heat the medium inside the tank body 102, and the conical filter layer is located at the bottom of the tank body 102 to help remove larger solid particles and ensure the quality of subsequent processes; the end cover 103 ensures the sealing of the opening of the tank body 102 to prevent steam leakage, and the feed port is convenient for adding raw materials, while the protective cover 104 protects the feed port from contamination during the non-feeding period; the motor 105 drives the shaft 106 and the mixing blades 107 fixed to the shaft 106, so that the syrup is fully mixed during the heating process, avoiding product quality problems caused by local overheating.

[0039] In the buffer tank 300, the gas tank 302 serves as a temporary storage container for the steam generated during the evaporation process. Its function is to smooth pressure fluctuations, ensure smooth operation of the system, and also help to recover some heat and improve energy efficiency. The sealing cover 303 maintains the airtightness of the system.

[0040] In the vacuum assembly 400, the pump body 401 creates and maintains a negative pressure environment by sucking air, which helps to lower the boiling point of the liquid, thereby achieving an efficient evaporation process at a lower temperature, and also provides power for the liquid circulation between each stage; the exhaust pipe 405, the exhaust valve 404 and the pressure gauge 403 work together to accurately control the vacuum degree. The appropriate vacuum degree can accelerate the evaporation rate while reducing energy consumption; the fixing part 402 ensures the stability of the exhaust pipe 405 to prevent loose connections or leakage due to vibration.

[0041] In the pipeline assembly 200, the control valve 201 adjusts the speed and direction of material flow to ensure that each evaporation stage can proceed according to the preset conditions; the conveying pipe 202 transports the material from one unit to another, and the trumpet-shaped opening design facilitates the smooth flow of material and reduces the risk of blockage.
