Description

Technical Field

[0001] This utility model relates to the field of sugar industry technology, and in particular to an evaporation device for the production of fructose syrup. Background Technology

[0002] High-fructose corn syrup is a syrup made from starch through enzymatic hydrolysis to produce glucose, followed by isomerization. Its main components are glucose and fructose. It is characterized by high sweetness, good solubility, and a unique flavor, and is widely used as a sweetener in the food, beverage, and baking industries. Due to its low cost and strong processing adaptability, it has become an important basic raw material in the modern food industry. Evaporation equipment is an industrial device that uses heating to vaporize the solvent in liquid materials, thereby achieving material concentration and separation. It typically consists of a heating chamber, an evaporation chamber, and a condenser, and is widely used in the food, chemical, and pharmaceutical industries. It can efficiently increase material concentration, reduce energy consumption, and different types can be selected according to the material characteristics to optimize the production process.

[0003] The material enters the heating chamber through the feed inlet, where the solvent is vaporized by steam. The resulting secondary steam and concentrated material enter the evaporation chamber. Inside the evaporation chamber, the gas-liquid mixture is separated by a separator. The concentrated syrup is discharged from the bottom, while the secondary steam enters the condenser and is either condensed into liquid by cooling water for recovery or discharge. The condensate formed after the heating steam releases heat in the heating chamber is discharged through a steam trap. This equipment recovers the waste heat of the secondary steam through multi-effect evaporation and a heat pump system to improve energy efficiency. The entire process is monitored and adjusted in real time by a control system to ensure efficient and stable operation by monitoring and adjusting parameters such as temperature and pressure.

[0004] In existing technologies, some feeding devices rely on manual operation, which is difficult to adapt to the needs of refined production. Moreover, manual intervention is prone to introducing errors. The evaporation device does not fully recover and utilize the waste heat of secondary steam, resulting in high steam consumption. Some gas-liquid separation efficiency is low, leading to unstable concentration effect and difficulty in meeting the high efficiency requirements of large-scale industrial production. The stable automation and highly adaptable evaporation technology of this equipment can better improve the efficiency, cost control and product quality stability of fructose syrup production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an evaporation device for producing fructose syrup, comprising a base plate 1, a motor 9, and a spindle 4 fixedly connected to the drive end of the motor 9. The motor 9 serves as a power source, providing initial power. The spindle 4 transmits the power from the motor 9, supports a roller 5 and drives it to rotate, and simultaneously serves as the rotation center of a support plate 3. A roller 5 is fixedly connected to the outer middle end of the spindle 4, providing flexible motion input for the connecting rod 8 and the round cover 7. A support plate 3 is rotatably connected to one side of the spindle 4. The support plate 3 is fixed by a support platform 2 at the bottom, providing lateral support for the spindle 4 and enhancing the structural integrity of the device. The structure is rigid to avoid overall shaking caused by the rotation of the spindle 4. The bottom of the support plate 3 is fixedly connected to the support platform 2, which fixes the support plate 3 and transfers the weight of the entire transmission mechanism to the bottom plate 1, and disperses the pressure to improve the shock resistance of the equipment. The roller 5 is fixedly connected to the fixed shaft 6. As the core component of motion conversion, the eccentric design of the axis of the fixed shaft 6 with the roller 5 can precisely control the movement trajectory of the connecting rod 8. The fixed shaft 6 is rotatably connected to the connecting rod 8. A round cover 7 is fixedly connected to one side of the connecting rod 8. The round cover 7 acts directly on the material and achieves the sealing between the separated material and the component through the drive of the connecting rod 8.

[0034] Reference Figure 1 , Figure 4A falling film evaporator 20 is fixedly connected to the top of the base plate 1. The falling film evaporator 20 is the core component used for the evaporation and concentration of fructose syrup. A top cover 21 is fixedly connected to the top of the falling film evaporator 20. The top cover 21 seals the top of the falling film evaporator 20 to prevent material leakage. A motor 22 is fixedly connected to the top of the top cover 21. The motor 22 drives the rotating shaft 23 to rotate, which in turn drives the flow distribution layer 24 to move. The driving end of the motor 22 is fixedly connected to the rotating shaft 23. The rotating shaft 23 transmits the power of the motor 22 to drive the flow distribution layer 24 to rotate, thereby realizing the dynamic dispersion of materials. The other end of the rotating shaft 23 is fixedly connected to the flow distribution layer 24. The centrifugal force of the rotating flow distribution layer 24 makes the materials more evenly dispersed. Dynamic dispersion reduces the retention of materials at the distributor and reduces the risk of scaling.

[0035] Reference Figure 1 and Figure 3 A support leg 12 is fixedly connected to the top of the base plate 1, increasing the stability of the device. A mixing tank 13 is fixedly connected to the top of the support leg 12. The mixing tank 13 serves as the mixing area for materials, thoroughly mixing the materials entering from the feed pipe 10. The feed pipe 10 is fixedly connected to the top of the mixing tank 13, acting as the channel for materials to enter the mixing tank 13. A groove is provided in the feed pipe 10 to facilitate the movement of the round cover 7 for quantitative material feeding. A funnel-shaped feeding container 11 is fixedly connected to the top of the feed pipe 10. The funnel shape design facilitates the collection and feeding of materials, improving feeding efficiency and storing a certain amount of material, reducing frequent feeding operations. A second motor 14 is fixedly connected to the bottom of the mixing tank 13. A rotating shaft 17 is fixedly connected to the drive end. The rotating shaft 17 connects to a motor 14 and a stirring blade 18, transmitting the motor's power to the stirring blade 18. Simultaneously, the lifting motion is achieved through the cooperation of a cam rod 16 and a sleeve 15. The sleeve 15 is rotatably connected inside the mixing tank 13. The cam rod 16 is fixedly connected to the outside of the rotating shaft 17. An annular groove is provided inside the sleeve 15 to facilitate the sliding of the cam rod 16 in the rotating shaft 17, thereby achieving the lifting and lowering of the rotating shaft 17. The stirring blade 18 is fixedly connected to the outside of the rotating shaft 17. The stirring blade 18 stirs the material inside the mixing tank 13, ensuring thorough mixing. A liquid outlet pipe 19 is fixedly connected to the right side of the outside of the mixing tank 13, serving as a channel for the material to be discharged from the mixing tank 13 after stirring.

[0036] Reference Figure 1 , Figure 4 and Figure 5A heat exchange tube 25 is fixedly connected to the bottom of the flow divider 24. The heat exchange tube 25 is the main site for material evaporation. The material flows inside the tube and exchanges heat with the heating medium outside the tube to achieve water evaporation and concentration. A condensate outlet 34 is fixedly connected to the left side of the falling film evaporator 20. The condensate outlet 34 discharges condensate in a timely manner to ensure the heat transfer effect inside the evaporator and prevent condensate accumulation from affecting the heat transfer between the heating steam and the material. A heating steam inlet 26 is fixedly connected to the right side of the falling film evaporator 20. The heating steam inlet 26 introduces heating steam into the falling film evaporator 20 to provide heat for material evaporation. A steam return pipe 27 is fixedly connected to the right side of the falling film evaporator 20. The steam return pipe 27 guides the secondary steam generated in the falling film evaporator 20 to the steam pipe 32. The bottom of the other end of the steam return pipe 27 is fixedly connected to the steam pipe 32. The steam pipe 32 transports the secondary steam to the separation device 29 for gas-liquid separation. The secondary steam is recycled and reused, improving energy efficiency and reducing energy consumption. A separation device 29 is fixedly connected to the bottom of the steam pipe 32 to separate the gas and liquid phases in the secondary steam, separating the entrained droplets and improving the purity of the steam. The separated pure steam can be further used as a heat source, improving energy utilization. A gas phase channel 28 is fixedly connected to the left side of the external part of the separation device 29, providing a channel for the reuse of steam and realizing the recycling of energy. A discharge pipe 33 is fixedly connected to the right side of the external part of the separation device 29, which discharges liquid material in a timely manner to avoid liquid accumulation in the separation device 29 and ensure separation effect. A baffle 30 and an umbrella plate separator 31 are fixedly connected inside the separation device 29. The baffle 30 and the umbrella plate separator 31 separate the droplets from the steam under the action of inertia and gravity, achieving efficient gas-liquid separation and improving separation efficiency and effect.

[0037] Working principle: Raw materials are fed into the funnel-shaped feeding container 11. Under the action of gravity, the raw materials naturally converge towards the feed pipe 10. When motor 9 is started, roller 5 rotates synchronously with spindle 4. The fixed shaft 6, which is fixedly connected inside roller 5, also begins to rotate. The fixed shaft 6 transmits the rotation to connecting rod 8, causing connecting rod 8 to drive the round cover 7 to perform regular reciprocating motion. The round cover 7 precisely controls the quantitative feeding of raw materials from the feed pipe 10. The raw materials enter the mixing tank 13. When motor 14 is started, the rotating shaft 17 and stirring blade 18 connected to motor 14 rotate to perform stirring. At the same time, the cam rod 16 and the annular groove in the sleeve 15 cooperate to achieve lifting and lowering motion. Therefore, the stirring blade 18 can not only stir the raw materials in the horizontal direction, but also in the vertical direction. Stirring expands the mixing range, allowing the raw materials to be mixed more thoroughly. The material then enters the falling film evaporator 20 from the stirring tank 13 through the liquid outlet pipe 19. The motor 22 on the top of the top cover 21 drives the rotating shaft 23 and the flow distribution layer 24 to evenly distribute the material into the heat exchange tube 25 to form a liquid film. Heating steam enters from the heating steam inlet 26 and heats the outside of the heat exchange tube 25, allowing the material to evaporate fully. The secondary steam generated by evaporation enters the separation device 29 through the steam return pipe 27 and the steam passage pipe 32. The baffle 30 and the umbrella plate separator 31 in the separation device 29 perform gas-liquid separation. The gas phase re-enters the falling film evaporator 20 through the gas phase channel 28 for recycling, while the liquid phase is discharged from the discharge pipe 33, and the condensate is discharged from the condensate outlet 34.
