Description

Technical Field

[0002] The crystallization process of glucose solution is a crucial step in the pharmaceutical and food industries, involving the cooling or evaporation of the glucose solution to induce crystal precipitation. The design of the crystallization apparatus directly impacts crystal quality and production efficiency. Common crystallization devices typically include a cooling system, a stirring device, and a crystallization container, controlling temperature and stirring speed to achieve uniform crystallization. However, in practice, existing crystallization devices often suffer from uneven heat transfer and insufficient stirring efficiency when processing high-concentration glucose solutions, leading to inconsistent crystal sizes and even localized supersaturation, thus affecting the quality of the final product. Furthermore, traditional crystallization devices have room for improvement in energy utilization; for example, the cooling system consumes a lot of energy and has a low heat recovery rate. While some devices improve crystallization by optimizing the stirring paddle design or adding external heating auxiliary equipment, they still face problems such as high energy consumption and operational complexity in large-scale production. Therefore, a more efficient and energy-saving glucose solution crystallization device is urgently needed to meet practical requirements. Utility Model Content

[0027] This utility model provides a glucose solution crystallization device, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the device includes a base 1, a main frame 2, a cooling assembly 3, a stirring assembly 4, a crystallization chamber 5, a heat exchange module 6, an adjusting plate 7, a guide vane 8, a flow divider 9, a temperature control unit 10, a heating ring 11, a drive shaft 12, stirring blades 13, a buffer cylinder 14, an elastic support 15, a limiting post 16, a sliding sleeve 17, a drive motor 18, a connecting rod 19, a fixing plate 20, a return pipe 21, a collection tank 22, a filter screen 23, and a discharge port 24. These components, through a reasonable structural design and spatial arrangement, jointly achieve efficient crystallization of glucose solution.

[0028] The base 1 serves as the fundamental support component for the entire device, with the main frame 2 fixedly connected to its top. The main frame 2 is a rectangular frame structure used for installing and securing other functional modules. The cooling assembly 3 is fixedly installed on the outer surface of the main frame 2, and has multiple cooling medium flow channels inside. The cooling medium circulates through these channels to cool the crystallization chamber 5. A distribution plate 9 is fixedly installed at the bottom of the cooling assembly 3. The distribution plate 9 has multiple distribution holes inside, distributed in a ring array, to evenly distribute the cooling medium to various parts of the cooling assembly 3. An adjusting plate 7 is fixedly connected to the top of the distribution plate 9. The outer surface of the adjusting plate 7 has a threaded structure that engages with the inner wall of the cooling assembly 3. By rotating the adjusting plate 7, the opening of the distribution holes can be changed, thereby controlling the flow rate of the cooling medium. This design allows the cooling process to be flexibly adjusted according to actual needs, ensuring precise temperature control.

[0029] The crystallization chamber 5 is fixedly connected to the center of the main frame 2. Its interior is a hollow structure used to contain the glucose solution and provide the necessary environmental conditions for crystallization. Multiple layers of guide vanes 8 are arranged spirally along the inner wall of the crystallization chamber 5 from top to bottom. The guide vanes 8 guide the glucose solution to form a stable flow path within the chamber, preventing localized stagnation or oversaturation. A discharge port 24 is located at the bottom of the crystallization chamber 5. A fixing plate 20 is fixedly connected inside the discharge port 24. A through hole is located at the center of the fixing plate 20, and the inner wall of the through hole has a threaded structure. The through hole mates with a connecting rod 19 through the threaded structure. One end of the connecting rod 19 is fixedly connected to the bottom of the discharge port 24, and the other end extends into the interior of the crystallization chamber 5. A flow divider 9 is fixedly connected to the extended portion of the connecting rod 19. Multiple guide vanes 8 are arranged radially on the outer surface of the flow divider 9. This design allows the crystals to flow uniformly along the path formed by the guide plate 8 during the discharge process, thereby improving the crystal collection efficiency.

[0030] The stirring assembly 4 is located at the center of the crystallization chamber 5. Its core component is the drive shaft 12, which is rotatably connected to the center of the crystallization chamber 5 via bearings. The top of the drive shaft 12 is fixedly connected to the output end of the drive motor 18, which is fixedly mounted on the top of the main frame 2 to drive the drive shaft 12 to rotate. Multiple stirring blades 13 are fixedly connected to the outer surface of the drive shaft 12. The stirring blades 13 are arc-shaped, and there is a gap between the outer edge of the arc-shaped stirring blades 13 and the inner wall of the crystallization chamber 5. The size of the gap is adjusted by the sliding sleeve 17. The sliding sleeve 17 is fitted onto the outer surface of the drive shaft 12 and fixed by the limiting post 16. One end of the limiting post 16 passes through the sliding sleeve 17 and is threadedly connected to the outer surface of the drive shaft 12. By adjusting the position of the sliding sleeve 17, the gap between the stirring blades 13 and the inner wall of the crystallization chamber 5 can be flexibly changed to adapt to the crystallization requirements of solutions of different concentrations. The stirring assembly 4 also includes a buffer cylinder 14, which is fixedly installed at the bottom of the drive shaft 12. Multiple elastic support members 15 are provided on the outer surface of the buffer cylinder 14. One end of each elastic support member 15 is fixedly connected to the outer surface of the buffer cylinder 14, and the other end is fixedly connected to the inner wall of the crystallization chamber 5. The elastic support members 15 absorb the vibrations generated during stirring through their own elastic deformation, thereby reducing the noise during device operation.

[0031] The heat exchange module 6 includes a heating ring 11, which is fixedly installed on the outer surface of the crystallization chamber 5. An electric heating wire is installed inside the heating ring 11, and the electric heating wire is controlled by a temperature control unit 10. The temperature control unit 10 is fixedly installed on the top of the main frame 2, and contains a temperature sensor and a controller. The temperature sensor monitors the temperature changes inside the crystallization chamber 5 in real time, and the controller adjusts the power of the electric heating wire based on the feedback signal from the temperature sensor, thereby maintaining the stability of the temperature inside the chamber. A return pipe 21 is fixedly connected to the outer surface of the heating ring 11. One end of the return pipe 21 is connected to the cooling assembly 3, and the other end is connected to the collection tank 22. A filter screen 23 is installed inside the return pipe 21 to intercept impurities in the cooling medium, ensuring the purity of the cooling medium. The collection tank 22 is fixedly installed at the bottom of the main frame 2, and contains a filter screen 23 to separate crystals and mother liquor. A drain port is located at the bottom of the collection tank 22, and the drain port is connected to an external recovery system through a pipe, thereby realizing the recycling of the mother liquor.

[0032] In actual operation, glucose solution is first injected into crystallization chamber 5. The drive motor 18 is then started, rotating the transmission shaft 12. The transmission shaft 12 drives the stirring blades 13 to stir the solution. During stirring, the arc-shaped stirring blades 13 and the guide vanes 8 work together to ensure a stable flow path within the crystallization chamber 5, preventing localized oversaturation. Simultaneously, the cooling assembly 3 cools the crystallization chamber 5 using internally circulating cooling medium. Waste heat generated during cooling is transferred to the heat exchange module 6 via the return pipe 21 for reuse. The temperature control unit 10 monitors the temperature changes within the crystallization chamber 5 in real time and automatically adjusts the operating status of the heating ring 11 and the cooling assembly 3 based on these changes, thereby achieving precise control of the crystallization process. After crystallization, the crystals are discharged through the discharge port 24, while the mother liquor passes through the filter screen 23 into the collection tank 22, and is ultimately recovered to an external system for reuse through the discharge port.

[0033] In the above embodiments, the combination of cooling component 3 and heat exchange module 6 effectively reduces the overall energy consumption of the device; the design of stirring component 4 improves the heat transfer uniformity of the solution; the cooperation of elastic support component 15 and buffer cylinder 14 reduces the noise during device operation; and the setting of filter screen 23 and liquid collection tank 22 achieves efficient separation of crystals and mother liquor, and the mother liquor is transported to an external recycling system for reuse through return pipe 21. This design not only improves the quality of crystals and production efficiency, but also significantly reduces resource waste and production costs.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0035] First, the glucose solution is injected into the crystallization chamber 5. During injection, the solution is evenly distributed into the chamber through multiple distribution holes of the distribution plate 9, avoiding localized excessive concentration. The design of the distribution plate 9 allows the cooling medium to be distributed to various parts of the cooling assembly 3 in a ring array, thus ensuring the uniformity of the cooling process. At this time, the operator can rotate the adjusting plate 7 to adjust the opening of the distribution holes to control the flow rate of the cooling medium, thereby achieving precise temperature control.

[0036] Subsequently, the drive motor 18 is started, driving the transmission shaft 12 to rotate. The rotation of the transmission shaft 12 further drives the stirring blades 13 to stir the solution. The stirring blades 13 have an arc-shaped design, and the gap between their outer edge and the inner wall of the crystallization chamber 5 can be flexibly adjusted by the sliding sleeve 17 and the limiting post 16. This design allows the stirring blades 13 to adapt to the needs of solutions of different concentrations, ensuring uniform flow of the solution throughout the crystallization chamber 5. At the same time, the spiral distribution of the guide vanes 8 guides the solution to form a stable flow path, avoiding local stagnation or oversaturation. During the stirring process, the buffer cylinder 14 and the elastic support 15 work together to absorb the vibration generated by stirring, significantly reducing the noise during device operation.

[0037] Meanwhile, the cooling assembly 3 cools the crystallization chamber 5 using an internally circulating cooling medium. The residual heat generated during cooling is transferred to the heat exchange module 6 via the return pipe 21. The electric heating wire inside the heating ring 11 automatically adjusts its power based on feedback signals from the temperature control unit 10 to maintain temperature stability within the crystallization chamber 5. The temperature sensor in the temperature control unit 10 monitors temperature changes within the chamber in real time and transmits the data to the controller. The controller then adjusts the operating status of the heating ring 11 and the cooling assembly 3 accordingly to ensure precise control of the crystallization process. A filter screen 23 is installed inside the return pipe 21 to intercept impurities in the cooling medium, ensuring its purity.

[0038] After the crystallization process is complete, the crystals are discharged through the discharge port 24. In the design of the discharge port 24, the fixing plate 20 cooperates with the connecting rod 19 through a threaded structure to ensure that the crystals can flow evenly along the radial path formed by the guide plate 8, thereby improving the crystal collection efficiency. The mother liquor enters the collection tank 22 through the filter screen 23, where the filter screen 23 separates the crystals and the mother liquor. Finally, the mother liquor is recovered to an external system for reuse through the discharge port.

[0039] During the above operations, the combination of cooling component 3 and heat exchange module 6 effectively reduces the overall energy consumption of the device. The design of stirring component 4 improves the heat transfer uniformity of the solution, avoiding the problem of uneven crystal particle size caused by uneven heat transfer in traditional devices. The cooperation between elastic support component 15 and buffer cylinder 14 reduces the noise during device operation and improves the comfort of the operating environment. The setting of filter screen 23 and liquid collection tank 22 realizes the efficient separation of crystals and mother liquor, and the mother liquor is transported to an external recycling system for reuse through return pipe 21, thereby significantly reducing resource waste and production costs.

[0040] By combining the above steps and principles, this invention not only solves the problems of uneven heat transfer and insufficient stirring efficiency in the prior art, but also optimizes the efficiency of heat recovery and utilization, providing a highly efficient and energy-saving glucose solution crystallization device for large-scale production.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
