[0002] Fructooligosaccharides refer to a mixture of fructosaccharides and other compounds derived from fructose groups, also known as fructosaccharides. The process of removing impurities from fructooligosaccharides through a series of technological steps to improve their purity is called purification, which requires the aid of purification equipment.

[0003] As disclosed in CN208791664U, a device for concentrating and purifying xylooligosaccharides relates to the field of xylooligosaccharide preparation technology. The device includes a rotating shaft and a separation device and an extraction device mounted on the rotating shaft. The separation device includes an inlet conduit, a separation conduit, and a connecting conduit. A heating plate is disposed on the outside of the separation device. A condensing ring is connected to the upper end of the separation conduit. A first heat insulation plate is disposed between the separation device and the condensing ring. At least a portion of the lower end of the separation conduit is located within the extraction device. A second heat insulation plate is disposed between the separation device and the extraction device. The extraction device includes a first annular channel, a second annular channel, and a connecting channel. A positive discharge terminal is disposed on the outside of the first annular channel, and a negative discharge terminal is disposed on the inside of the second annular channel.

This utility model provides a highly efficient and stable device for concentrating and purifying xylooligosaccharides, achieving high extraction purity. It operates as a single unit with high controllability, requires no added reagents, and is convenient to use.

[0004] However, the existing technology lacks a sieving structure to sieve the oligofructose being processed, making it inconvenient to remove impurities from the oligofructose. Moreover, during the purification process, the oligofructose tends to adhere to the inner wall of the device, making it inconvenient to disassemble and clean the device after use. This leads to the problem of residues inside the device, as is the case in the comparative patents listed above.

[0005] To address this issue, we propose a fructooligosaccharide purification device with an initial impurity separation treatment. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see Figures 1-9 The present invention provides the following technical solution.

[0035] Example 1: To address the problem in existing technologies where the lack of a sieving structure hinders the sieving of fructooligosaccharides and makes it inconvenient to remove impurities, this example provides a fructooligosaccharide purification device with a preliminary impurity separation process. The device comprises a purification cylinder 1, a feeding cylinder 2, a screen 3, a fixing plate 4, and a fixing bolt 5. The feeding cylinder 2 is fixedly connected to the upper right end of the purification cylinder 1. The screen 3 is inserted and installed in the middle of the feeding cylinder 2. Fixing plates 4 for positioning are engaged on both the front and rear sides of the right end of the screen 3. The fixing plates 4 drive the screen 3 to form a detachable structure in the middle of the feeding cylinder 2. The fixing plates 4 are hinged to the front and rear ends of the feeding cylinder 2, and the fixing plates 4 and screen 3 are positioned by fixing bolts 5. The fixing bolts 5 and fixing plates 4, as well as the fixing bolts 5 and screen 3, are all threaded connections. Figure 1 , Figure 2 and Figure 3As shown, when fructooligosaccharides are added to the feeding cylinder 2, the fructooligosaccharides added to the feeding cylinder 2 can be screened, thus facilitating the separation of impurities in the fructooligosaccharides. The sieved and filtered fructooligosaccharides enter the purification cylinder 1 through the feeding cylinder 2. In addition, after use, the fixing bolt 5 can be rotated to disengage the fixing bolt 5 from the fixing plate 4, thereby loosening the limit between the fixing plate 4 and the sieve 3. Then, the fixing plate 4 can be flipped over, and the fixing plate 4 can rotate with the feeding cylinder 2, disengaging the fixing plate 4 from the sieve 3, thereby loosening the limit between the sieve 3 and the feeding cylinder 2. Then, the sieve 3 can be removed from the feeding cylinder 2, which facilitates the disassembly and cleaning of the sieve 3 and prevents the sieve 3 from becoming clogged during long-term use.

[0036] Example 2: To address the problem in existing technologies where fructooligosaccharides easily adhere to the inner wall of the purification device during the purification process, this example provides a fructooligosaccharide purification device with impurity separation pretreatment. The device includes a heating cylinder 6, a heating device 7, a cover plate 8, a motor 9, a stirring rod 10, and a scraper 11. The heating cylinder 6 is fixedly connected to the middle of the outer side of the purification cylinder 1. The heating device 7 is installed inside the heating cylinder 6. The motor 9 is fixedly installed at the upper end of the cover plate 8, and the output end of the motor 9 is fixedly connected to the stirring rod 10. The distal end of the stirring rod 10 is fixedly connected to the scraper 11. The motor 9 drives the stirring rod 10 and the scraper 11 to rotate within the purification cylinder 1. The scraper 11 is fitted against the inner wall of the purification cylinder 1. Figure 4 , Figure 5 and Figure 6 As shown, after the oligofructose is added to the purification cylinder 1, the purification cylinder 1 is heated by the heating device 7 installed inside the heating cylinder 6. At the same time, the motor 9 is started, and the motor 9 drives the stirring rod 10 and the scraper 11 to rotate in the purification cylinder 1, stirring and mixing the oligofructose inside the purification cylinder 1 to achieve the purification effect. In addition, the scraper 11 can also scrape off the oligofructose adhering to the inner wall of the purification cylinder 1. After purification, the oligofructose can be discharged through the discharge valve 12.

[0037] Example 3: To address the problem in existing technologies where disassembly and cleaning of the device is inconvenient after use and residues are easily left inside, this example provides the following technical solution: an oligofructose purification device with impurity separation pretreatment, comprising a fixing mechanism 13 symmetrically arranged at the front and rear ends of a cover plate 8. The fixing mechanism 13 consists of a movable plate 14, fixing blocks 15, fixing rods 16, connecting plates 17, and connecting caps 18. The movable plates 14 are respectively fitted to the front and rear sides of the upper end of the cover plate 8, and a sliding structure is formed between the movable plates 14 and the fixing blocks 15. The fixing blocks 15 are respectively fixedly connected to the front and rear sides of the upper end of the cover plate 8, and a fixing rod 16 is fixedly connected to the side of the movable plate 14 away from the vertical central axis of the cover plate 8. The fixing rod 16 is inserted into the upper end of the connecting plate 17, and the connecting plate 17 is respectively fixedly connected to the front and rear sides of the upper end of the purification cylinder 1. A connecting cap 18 for locking and limiting is threaded onto the outer surface of the fixing rod 16, and the connecting cap 18 is fitted to the side of the connecting plate 17. Figure 8 and Figure 9 As shown, after processing is completed, the power is turned off. By rotating the connecting cap 18, which is threaded onto the outer surface of the fixed rod 16, the connecting cap 18 is disengaged from the fixed rod 16, thereby loosening the limit between the fixed rod 16 and the connecting plate 17. Then, the movable plate 14 is pulled, and the movable plate 14 slides between itself and the fixed block 15. The movable plate 14 drives the fixed rod 16 to move out of the connecting plate 17, thereby loosening the limit between the cover plate 8 and the purification cylinder 1. Then, the cover plate 8 is pulled upward, causing the cover plate 8 to move the stirring rod 10 and the scraper 11 out of the purification cylinder 1, thus facilitating thorough cleaning of the inside of the device and preventing residue.
