Description

Technical Field

[0001] This utility model relates to the technical field of fructose production equipment, and in particular to a rapid evaporation device for the production of crystalline fructose. Background Technology

[0002] Crystalline fructose is a monosaccharide, the crystalline form of fructose, characterized by high sweetness, good flavor, and rapid metabolism. It is typically produced from raw materials such as corn starch through processes including enzymatic hydrolysis, isomerization, separation and purification, evaporation and concentration, and crystallization. In the production of crystalline fructose, the evaporation process is a crucial step affecting product quality and production efficiency. Its core principle is to achieve a supersaturated state in the fructose stock solution by evaporating water, thereby enabling crystallization.

[0003] Most existing equipment lacks an effective automatic stirring mechanism. During the evaporation process, fructose stock solution is prone to local temperature and concentration differences due to stagnation or poor flow. The temperature in the area near the heat source is too high, which may cause the fructose molecules to undergo Maillard reaction or decompose due to high temperature, destroying the natural flavor and nutritional characteristics of the product. The evaporation rate in the area far from the heat source is slow, and the concentration distribution of the stock solution is uneven. The final crystal particles have large differences in size, which affects the stability of product quality. Therefore, a rapid evaporation device for the production of crystalline fructose is proposed to solve the above problems. Utility Model Content

The spring assists in enhancing the sealing force, thereby achieving the effect of closing the channel tightly and avoiding the effect of gas pressure fluctuations causing a sudden drop in evaporation efficiency or local overheating.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of a rapid evaporation device for producing crystalline fructose, comprising a support plate 1. A support assembly is fixedly connected to the top of the support plate 1. The large surface area of ​​the plate disperses the overall weight of the device, preventing tilting due to vibration or shift in the center of gravity during operation. A heating shell 4 is fixedly connected to the top of the support assembly. An arc-shaped plate 5 is fixedly connected inside the heating shell 4. A drive assembly is fixedly connected inside the arc-shaped plate 5. A connecting column a10 is fixedly connected inside the drive assembly. The arc-shaped plate 5 provides stable support for the drive assembly. The arc-shaped surface can effectively guide these splashed materials, allowing the materials to flow along the surface of the arc plate 5 and slide into the bottom of the heating shell 4, reducing the adhesion of materials to other components inside the heating shell 4 and improving the utilization rate of materials. A cleaning component is fixedly connected to the outside of the connecting column a10, a fixing rod a13 is fixedly connected to the bottom of the arc plate 5, a fixing ring 14 is fixedly connected to the bottom of the fixing rod a13, an agitation component is fixedly connected to the bottom of the arc plate 5, and a driven plate 15 is provided on the outside of the drive component. The fixing ring 14 limits and guides the driven plate 15. When the driven disk 15 rotates with the turntable 9, the retaining ring 14 prevents the driven disk 15 from radially shifting. The support assembly includes four connecting rods a2, the bottom of which is fixedly connected to the top of the support disk 1. A support column 3 is fixedly connected to the adjacent side of the four connecting rods a2, and the top of the support column 3 is fixedly connected to the bottom of the heating shell 4. The drive assembly includes a support rod 6, the outside of which is fixedly connected to the inside of the arc plate 5. A motor 7 is fixedly connected to the top of the support rod 6, and a rotating shaft 8 is fixedly connected to the drive end of the motor 7. A turntable 9 is fixedly connected to the bottom of the rotating shaft 8, and the outside of the turntable 9 is in contact with the outside of the driven disk 15. The cleaning assembly includes a connecting rod b11. The outer left side of the connecting rod b11 is fixedly connected to the outside of the connecting column a10. The right side of the connecting rod b11 is fixedly connected to the scraper 12. The outer right side of the scraper 12 is in contact with the inner wall of the heating shell 4. When the cleaning component rotates, the scraper 12 can scrape off the fructose crystals attached to the inner wall of the heating shell 4 in real time, improving the utilization rate of raw materials. The outer right side of the scraper 12 is in contact with the inner wall of the heating shell 4. The stirring component includes the connecting column b16. The outer side of the connecting column b16 is fixedly connected to the inside of the driven disk 15. The bottom of the connecting column b16 is fixedly connected to the stirring claw 17. During the rotation, the stirring claw 17 can stir the fructose solution inside the heating shell 4, so that the solution is heated evenly and avoids local overheating.

[0032] Reference Figure 2 , Figure 3A power assembly is fixedly connected to the bottom of the heating shell 4, and a sealing cover 21 is fixedly connected to the top of the heating shell 4. An air outlet duct 22 is fixedly connected to the outer top of the heating shell 4. The power assembly includes an L-shaped support plate 18, the top of which is fixedly connected to the bottom of the heating shell 4. An air pump 19 is fixedly connected to the top of the L-shaped support plate 18. The sealing cover 21 prevents uncontrolled entry of external air into the heating shell 4, ensuring a stable negative pressure environment created by the air pump 19. An air outlet 20 is fixedly connected to the input end of the air pump 19, serving as the power source for gas suction. The air outlet 20 draws the gas inside the heating shell 4 outward, creating a certain negative pressure environment inside the heating shell 4. The negative pressure lowers the boiling point of the fructose solution, enabling rapid evaporation at low temperatures and preventing high temperatures from damaging the fructose components. The air outlet 20 is fixedly connected to the bottom of the heating shell 4.

[0033] Reference Figure 1 , Figure 4 The air outlet duct 22 has an internal cavity 29. A fixed rod b28 is fixedly connected inside the air outlet duct 22. A limiting post 24 is fixedly connected to the outside of the fixed rod b28. A sliding sleeve 25 is slidably connected to the outside of the limiting post 24. Two rotating rods 26 are rotatably connected to the outside of the sliding sleeve 25. The far ends of the two rotating rods 26 are fixedly connected to the inside of the air outlet duct 22. A baffle 23 is slidably connected to the outside of the limiting post 24. The limiting post 24 restricts the sliding sleeve 25 and the baffle 23 to only move upwards along the axial direction. When the air pump 19 is drawing air, it relies on the negative pressure inside the heated outer shell 4 and the elastic force of the spring 27 to tightly seal the sealing surface, blocking the entry of external air. When the air pump stops working, the external air pressure pushes the baffle 23 to move against the elastic force of the spring 27, opening the gas passage and achieving air pressure balance. The bottom of the inner side of the baffle 23 is fixedly connected to the spring 27, and the top of the spring 27 is fixedly connected to the bottom of the sliding sleeve 25. When the external air pressure is greater than the internal air pressure, the spring 27 is compressed, and the baffle 23 moves to open the passage.

[0034] Working principle: After the equipment is started, the fructose solution enters the heating shell 4. The motor 7 in the drive assembly starts and drives the turntable 9 to rotate via the rotating shaft 8. The turntable 9 contacts the driven disc 15, generating friction and causing the driven disc 15 to rotate. The driven disc 15 drives the stirring claw 17 of the stirring assembly to rotate via the connecting column b16. The stirring claw 17 stirs the fructose solution in the heating shell 4, ensuring uniform heating of the solution and preventing local overheating that could lead to caramelization. At the same time, it accelerates the evaporation rate of water in the solution.

[0035] During the stirring process, some fructose solution may splash. The arc-shaped plate 5, due to its arc-shaped structure, guides the splashed material, allowing it to slide along the plate into the bottom of the main body 4, improving material utilization and reducing cleaning difficulty. Driven by the connecting column a10, the cleaning component rotates the connecting rod b11, which in turn rotates the scraper 12. The scraper 12 contacts the inner wall of the main body 4, scraping away fructose crystals adhering to the inner wall in real time to prevent affecting heat transfer efficiency or causing blockage, and also increasing raw material utilization.

[0036] The air pump 19 in the power unit starts working, drawing gas out of the device body 4 through the air outlet 20, creating a negative pressure environment inside the device body 4. The sealing cover 21 on the top of the device body 4 ensures the airtightness of the internal space, maintains the stability of the negative pressure environment, and prevents external impurities from entering and contaminating the solution. When the air pump 19 draws in air, the one-way valve structure inside the air outlet duct 22 closes tightly under the action of the negative pressure and the elastic force of the spring 27, preventing external air from entering. When it is necessary to balance the air pressure, the external air pressure pushes the baffle 23 to move against the elastic force of the spring 27, opening the channel to achieve air pressure balance.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
