Description

A concentration device for xylooligosaccharide purification Technical Field

[0001] This utility model relates to the field of concentration and purification equipment technology, specifically a concentration device for the purification of xylooligosaccharides. Background Technology

[0002] With the rapid development of the functional food and health product industry, xylooligosaccharides, as an important prebiotic, have received widespread attention due to their excellent physiological activity and health benefits. Purification is a key step in the production of xylooligosaccharides, and concentration equipment plays a crucial role in this process.

[0003] The shortcomings of existing technology:

[0004] Currently, common concentration equipment mainly employs membrane separation technology. This involves applying pressure to force the solvent and small molecules in the feed solution through a filter membrane, thereby concentrating the solute. However, existing technologies typically place the feed material directly on top of the filter membrane, relying on high pressure to drive permeation. While this method is effective with small amounts of feed material, as the amount increases and the thickness of the packing grows, it leads to a significant increase in permeation resistance, a decrease in membrane flux, and a reduction in concentration efficiency. Therefore, traditional concentration equipment is no longer sufficient to meet the concentration requirements for xylooligosaccharide purification. Summary of the Invention

[0005] The purpose of this invention is to provide a concentration device for the purification of xylooligosaccharides, so as to solve the problems mentioned in the background art.

[0032] Please refer to Figures 1-4. This utility model provides a technical solution for a concentration device for xylooligosaccharide purification: A concentration device for xylooligosaccharide purification includes a base 1. An adjustment mechanism 2 is installed on the upper surface of the base 1. An installation box 3 is movably installed on the adjustment mechanism 2. A sleeve 4 is fixedly installed on one side of the installation box 3. The end of the sleeve 4 is sealed. A feed pipe 5 and a pressure boosting pipe 6 are connected inside the sleeve 4. A purification mechanism 7 is movably installed inside the installation box 3. A drain pipe 8 is installed at the lower end of the installation box 3. The purification mechanism 7 includes a positioning column 701, a motor 704, a liquid permeation ring 707, and a rolling assembly 709. The positioning column 701 is fixedly installed at one end inside the installation box 3. Sealed bearings 702 are installed at the ends of both the positioning column 701 and the sleeve 4. A concentration cylinder 703 is rotatably and sealed between the positioning column 701 and the sleeve 4 through the sealed bearings 702. The sealed bearings 702 ensure the sealing of the connection while also allowing for flexible rotation. The ports of the feed pipe 5 and the booster pipe 6 pass through the sleeve 4 and are located inside the concentration cylinder 703. The motor 704 is mounted on the inner wall of one side of the mounting box 3. A drive gear 705 is mounted on the output end of the motor 704. A gear ring 706, meshing with the drive gear 705, is mounted on the end wall of one end of the concentration cylinder 703. A liquid permeation ring 707 is formed on the cylinder wall of the concentration cylinder 703. A filter membrane 708, a nanofiltration membrane, is fixedly attached to the inner wall of the liquid permeation ring 707. The liquid permeation ring 707 mainly supports the filter membrane 708, which is used for the permeation and removal of small molecules in the raw material. The rolling assembly 709 is mounted on the end of the positioning column 701, located inside the concentration cylinder 703.

[0033] When the equipment needs to operate, the external feeding device first feeds an appropriate amount of raw material into the concentration cylinder 703 through the feed pipe 5. The feed pipe 5 can extend to the upper part of the middle of the concentration cylinder 703 to release the raw material, as shown in Figure 4, to avoid the raw material accumulating on one side of the concentration cylinder 703. At the same time, the external pressurizing device increases the air pressure inside the concentration cylinder 703 to the standard value through the pressurizing pipe 6. Then, the motor 704 is started. The motor 704 drives the concentration cylinder 703 to rotate slowly through the cooperation of the drive gear 705 and the gear ring 706. The xylooligosaccharide raw material to be concentrated can then roll synchronously inside the concentration cylinder 703. Under the action of high-pressure rolling, small molecules in the raw material permeate through the filter membrane 708 and are discharged.

[0034] The purification mechanism 7 achieves the effect of rolling concentration of xylooligosaccharide raw materials in the concentration cylinder 703. Compared with simply using high pressure concentration by stacking the raw materials on the filter membrane 708, the permeation resistance is small, the drainage is smooth, and the continuous slow mixing also significantly improves the concentration efficiency and shortens the concentration time.

[0035] The rolling assembly 709 includes a mounting shaft 7091, which is fixedly mounted on one end of the positioning column 701. A limiting disc 7092 is mounted on one end of the mounting shaft 7091 and on the shaft body. A pressure ring 7093 is movably sleeved on the mounting shaft 7091 between the limiting discs 7092 for rolling the raw material. When feeding raw material into the concentration cylinder 703, the thickness of the raw material is controlled to not exceed the holes on both sides of the pressure ring 7093 to prevent raw material from entering the pressure ring 7093. During the concentration operation of this equipment, the pressure ring 7093 presses against the xylooligosaccharide raw material and rolls synchronously on the mounting shaft 7091 as the concentration cylinder 703 rotates, applying a certain downward pressure to the raw material and accelerating its penetration.

[0036] The rolling assembly 709 provides a certain downward pressure to the xylooligosaccharide raw material during concentration, ensuring sufficient internal compression of the raw material, further improving the concentration efficiency, and better meeting the actual needs of current xylooligosaccharide purification.

[0037] The adjusting mechanism 2 includes a positioning seat 201 and a discharge pipe 203. The positioning seat 201 is fixedly installed at one end of the upper surface of the base 1. The upper end of the positioning seat 201 is rotatably connected to one side of the lower end of the mounting box 3. A telescopic rod 202 is installed on the side of the base 1 away from the positioning seat 201. The upper end of the telescopic rod 202 is movably connected to the upper end of the mounting box 3. The discharge pipe 203 is located on the edge of one side of the concentrator 703, above the positioning seat 201. A discharge trough 204 is provided at the lower end of the mounting box 3 on the side adjacent to the discharge pipe 203.

[0038] When the purified raw material needs to be discharged from the concentration cylinder 703, the pressure is first released by the external pressurization equipment through the pressurization pipe 6, then the port of the discharge pipe 203 is opened, and the telescopic rod 202 is started. The telescopic rod 202 pushes the mounting box 3 to rotate around the positioning seat 201 as the axis, so that the box body is tilted as a whole, and the raw material in the concentration cylinder 703 can be discharged through the discharge pipe 203 and the discharge trough 204.

[0039] A baffle ring 9 is installed on one side of the inner wall of the concentration cylinder 703. The baffle ring 9 can prevent the raw material from splashing onto the positioning column 701 and the sealing bearing 702 during the rolling concentration process, which would cause corrosion.

[0040] The diameter of the limiting disc 7092 is larger than the diameter of the holes at both ends of the pressure ring 7093 to prevent the pressure ring 7093 from falling off the limiting disc 7092. At the same time, as shown in Figure 2, ball bearings are provided on the disc wall of the limiting disc 7092, and the two sides of the pressure ring 7093 slide in close contact with the disc wall of the limiting disc 7092, further ensuring that the xylooligosaccharide raw material cannot enter the pressure ring 7093.

[0041] Both ends of the mounting box 3 are equipped with support rings 10 for auxiliary support of the concentration cylinder 703, which improves the rolling stability of the concentration cylinder 703.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
