Description

Technical Field

[0001] This utility model relates to the field of nervonic acid purification technology, and more specifically, to a device for purifying nervonic acid extracted from garlic fruit. Background Technology

[0002] Extracting nervonic acid from garlic fruit requires a systematic production equipment. Existing purification techniques, such as those in application number CN202321026613.3, involve purification through extrusion. This extrusion method is outdated and cannot improve purity through repeated extrusion, thus limiting its ability to increase purity. A novel purification method needs to be designed. Utility Model Content

[0003] To address the above deficiencies, this invention provides a device for purifying nervonic acid extracted from garlic fruit, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A purification apparatus for extracting nervonic acid from garlic fruit includes a new solution, crystals, impurities, a crystallization vessel, a filter tank, a refrigeration system, and a recovery tank; and also includes: The stirring shaft and stirring blades are connected to the refrigeration system, which includes a refrigeration medium. The refrigeration medium moves from the upper end to the lower end of the stirring shaft, passing through the stirring blades along the way. The crystallization vessel is connected to the filter tank. Crystallization filter plates separate the mixed crystals and impurities. The crystallization filter plates are placed inside the filter tank. A circulating pump transports the separated crystals to a crystallization vessel for repeated crystallization. Repeating this process allows for the extraction of high-purity crystals.

[0005] Furthermore, sealed bearings are installed at both the upper and lower ends of the crystallization vessel, and the stirring shaft is installed inside the sealed bearings. The stirring shaft has openings at both ends and rotary sealing joints at both ends. The rotary sealing joints are connected to the refrigeration system. The stirring blades are U-shaped, fit the outline of the crystallization vessel, and are connected to the stirring shaft. The refrigeration medium moves from top to bottom. A drive mechanism is installed at the upper end of the crystallization vessel, and the drive mechanism drives the stirring shaft to rotate.

[0006] Furthermore, the crystallization filter plate is installed at the lower part of the filter tank, and a reflux pipe is installed on one side of the filter tank. The circulation pump is installed on the reflux pipe, with the upper end of the reflux pipe connected to the crystallization kettle and the lower end connected to the filter tank.

[0007] Furthermore, the crystallization filter plate is placed horizontally.

[0008] Furthermore, the crystallizing filter plate is placed at an angle, and a telescopic rod is installed on the side wall of the filter tank. A scraper is installed at the telescopic end of the telescopic rod, and the scraper contacts the crystallizing filter plate. The scraper is hinged to the telescopic end of the telescopic rod.

[0009] Furthermore, temperature sensors are installed on the inner wall of the crystallization vessel and on the stirring shaft.

[0010] Furthermore, the frame, crystallizing vessel, and filter tank are fixedly connected to the frame, with the crystallizing vessel and filter tank arranged vertically.

[0011] The beneficial effects of this invention are as follows: It employs a low-temperature crystallization method, utilizing the physical principle that the solubility of different substances in specific solvents decreases at different rates with decreasing temperature; nervonic acid (cis-15-tetracosenoic acid) and its main impurities (such as erucic acid, cis-13-tetracosenoic acid) are very similar in molecular structure, differing only slightly in carbon chain length and double bond position; this minute difference leads to different solubility behaviors at low temperatures in specific organic solvents (such as acetone, ethanol, n-hexane, n-pentanol, etc.), with nervonic acid preferentially precipitating upon cooling; The crystals obtained in the first step are redissolved in fresh solvent, and then the above-described cooling crystallization process is repeated. Each repetition increases the purity of the product. The scraper prevents crystals from adhering to the crystallization filter plate, effectively preventing the crystallization filter plate from clogging. Attached Figure Description

[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0014] This application provides a device for purifying nervonic acid extracted from garlic fruit. Please refer to the following: Figures 1-3 It includes: 1. New solution; 2. Crystals; 3. Impurities; 4. Crystallization vessel; 5. Filter tank; 6. Refrigeration system; and 7. Recovery tank; and also includes: The stirring shaft 8 and stirring blades 9 are connected to the refrigeration system 6. The refrigeration system 6 includes a refrigeration medium. The refrigeration medium moves from the upper end to the lower end of the stirring shaft 8 and flows through the stirring blades 9. The crystallization vessel 4 is connected to the filter tank 5. Crystallization filter plate 10 separates the mixed crystals 2 and impurities 3. Crystallization filter plate 10 is installed inside filter tank 5. The circulating pump 11 transports the separated crystals 2 to the crystallization vessel 4 for repeated crystallization. Repeating the above process can extract high-purity crystals 2.

[0015] In practical applications, during operation, the new solution 1 and crude nervonic acid are transported into the crystallization vessel 4. Then, the drive mechanism 14 is controlled to rotate the stirring shaft 8 and stirring blades 9. At the same time, the refrigeration system 6 delivers the cooling medium to the stirring shaft 8 and stirring blades 9 for stable cooling. During the cooling process, the physical principle that the solubility of different substances in specific solvents decreases at different rates with decreasing temperature is utilized. Nervonic acid (cis-15-tetracosenoic acid) and its main impurities (such as erucic acid and cis-13-tetracosenoic acid) are very similar in molecular structure, with only slight differences in carbon chain length and double bond position. This slight difference leads to different solubility behaviors at low temperatures in specific organic solvents (such as acetone, ethanol, n-hexane, n-pentanol, etc.). During cooling, nervonic acid will preferentially precipitate out. After crystallization has occurred for a certain period of time, the drive mechanism 14 stops rotating, and the valve between the crystallization vessel 4 and the filter tank 5 opens, allowing the crystallized mixture to be transported into the filter tank 5. Through the action of the crystallization filter plate 10, crystal 2 (high-purity nervonic acid) is filtered onto the filter plate 10. Then, the crystal 2 is returned to the crystallization vessel 4 by the circulation pump 11. At this point, the bottom of the filter tank 5 contains the old solution, which is discharged to the recovery tank 7 for recycling. New solution 1 (such as acetone, ethanol, n-hexane, n-pentanol, etc.) is then transported into the crystallization vessel 4 for re-crystallization. By repeating the above process, high-purity nervonic acid can be obtained.

[0016] Reference Figure 1 , Figure 2 , Figure 3 The crystallizing vessel 4 is equipped with sealed bearings 12 at both ends. The stirring shaft 8 is installed inside the sealed bearings 12. The stirring shaft 8 has openings at both ends and is equipped with rotary sealing joints 13 at both ends. The rotary sealing joints 13 are connected to the refrigeration system 6. The stirring fins 9 are U-shaped and fit the contour of the crystallizing vessel 4 and are connected to the stirring shaft 8. The refrigeration medium moves from top to bottom. The upper end of the crystallizing vessel 4 is equipped with a drive mechanism 14, which drives the stirring shaft 8 to rotate.

[0017] In practical applications, the sealed bearing 12 facilitates the stable rotation of the stirring shaft 8, the rotary sealing joint 13 facilitates the flow of the refrigerant medium, and the stirring shaft 8 can rotate stably. The stirring fins 9 facilitate stirring and can quickly exchange heat with the new solution, thereby reducing the temperature of the new solution.

[0018] Reference Figure 1 , Figure 2 , Figure 3 The crystallization filter plate 10 is installed at the lower position of the filter tank 5. A return pipe 15 is installed on one side of the filter tank 5. The circulation pump 11 is installed on the return pipe 15. The upper end of the return pipe 15 is connected to the crystallization vessel 4, and the lower end is connected to the filter tank 5.

[0019] In practical applications, the crystals 2 (high-purity nervonic acid) can be filtered above the crystal filter plate 10 through the action of the crystal filter plate 10. Then, the crystals 2 are returned to the crystallization vessel 4 through the action of the circulation pump 11. At this time, the bottom of the filter tank 5 is the old solution, which is discharged to the recovery tank 7 for recycling.

[0020] Reference Figure 1 , Figure 2 , Figure 3 The crystallization filter plate 10 is placed horizontally.

[0021] In practical applications, placing the crystallization filter plate 10 horizontally can optimize the structure, reduce maintenance frequency, and lower production costs.

[0022] Reference Figure 1 , Figure 2 , Figure 3 The crystallizing filter plate 10 is placed at an angle, and a telescopic rod 17 is installed on the side wall of the filter tank 5. A scraper 18 is installed at the telescopic end of the telescopic rod 17. The scraper 18 is in contact with the crystallizing filter plate 10, and the scraper 18 is hinged to the telescopic end of the telescopic rod 17.

[0023] In practical applications, the inclined placement of the crystallization filter plate 10 facilitates the flow of crystals 2 toward the circulation pump 11. The extension of the telescopic rod 17 can scrape the crystals 2 adhering to the surface of the crystallization filter plate 10 to the position of the return pipe 15, thereby minimizing the residue of crystals 2.

[0024] Reference Figure 1 , Figure 2 , Figure 3 Temperature sensors 19 are installed on the inner wall of the crystallization vessel 4 and on the stirring shaft 8.

[0025] In practical applications, the temperature sensor 19 helps staff understand the working conditions inside the crystallization vessel 4.

[0026] Reference Figure 1 , Figure 2 , Figure 3It includes a frame 20, a crystallizing vessel 4 and a filter tank 5, which are fixedly connected to the frame 20. The crystallizing vessel 4 and the filter tank 5 are arranged vertically.

[0027] In practical applications, arranging the crystallization vessel 4 and the filter tank 5 vertically is beneficial for the flow of crystals 2 and impurities 3.
