Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cyclodextrin finishing, in particular to a decolorization device for cyclodextrin and cyclodextrin derivatives. Background Technique
[0002] Cyclodextrin is a general term for a series of cyclic oligosaccharides generated by the action of cyclodextrin glucosyltransferase produced by Bacillus on amylose. During the production process of cyclodextrin and cyclodextrin derivatives, due to the presence of reducing substances, the product solution turns yellow under conditions such as alkalinity or high temperature, seriously affecting the quality of the product. Therefore, during the processing of cyclodextrin and cyclodextrin derivatives, decolorization treatment is generally carried out, and thus a decolorization device is used. However, during the use of the existing decolorization device, there is often a poor heating effect. The traditional heating method cannot evenly heat the decolorization tank, resulting in a poor decolorization effect. Secondly, a stirring rod is usually arranged inside the existing decolorization device to stir the raw materials. However, since the installation position of the stirring rod is mostly fixed, the stirring range is relatively limited and the stirring effect is poor, which is not conducive to use. Therefore, a decolorization device for cyclodextrin and cyclodextrin derivatives is proposed. Content of the Utility Model

[0028] During use, the cyclodextrin raw material and the decolorizing agent are injected into the interior of the decolorizing tank 4 through the feed hole 7 and the feed hopper 5. Then, the first solenoid valve 6 is closed through the controller, and the stepping motor 151 and the two hot air blowers 12 are started. The two hot air blowers 12 will convey hot air into the two boxes 10, and then spray it to the left and right ends of the decolorizing tank 4 through the left and right air outlet holes 11, so as to heat the decolorizing tank 4.

[0029] In summary, for the decolorization device of cyclodextrin and cyclodextrin derivatives, by starting the stepping motor 151 and two hot air blowers 12, the two hot air blowers 12 will deliver hot air into the two boxes 10, and then spray it to the left and right ends of the decolorization tank 4 through the left and right air outlets 11, so as to heat the decolorization tank 4. The stepping motor 151 will drive the driving bevel gear 152 to rotate, and then drive the transmission shaft 142 and the driving gear 143 to rotate through the driven bevel gear 153. Then, the driven gear 144 will drive the two cylinders 3 and the decolorization tank 4 as a whole to rotate, so that the outer circumference of the decolorization tank 4 can be in contact with the hot air, thereby heating the decolorization tank 4 evenly, improving the heating efficiency, and ensuring the decolorization quality. Secondly, by starting the servo motor 181 and the driving motor 23, the servo motor 181 will drive the stirring shaft 182 and the stirring rod 183 to rotate, so as to stir the cyclodextrin raw material and the decolorizing agent. The driving motor 23 will drive the worm 24 to rotate, and then drive the mounting shaft 19 and the disc 21 to rotate through the worm gear 25. During the rotation of the disc 21, it will squeeze the inner top wall or the inner bottom wall of the traction frame 20, so as to drive the traction frame 20 and the moving frame 17 to move up and down reciprocally, and then drive the stirring shaft 182 and the stirring rod 183 to move up and down reciprocally, so that the stirring rod 183 cooperates with the up and down reciprocating movement during rotation, so as to expand the stirring range, and then can fully stir the cyclodextrin raw material and the decolorizing agent in the decolorization tank 4, finally improving the decolorization effect, and solving the problems that in the process of using the existing decolorization device, there is often a poor heating effect, the traditional heating method cannot make the decolorization tank evenly heated, resulting in a poor decolorization effect. Secondly, there are usually stirring rods installed inside the existing decolorization device to stir the raw materials. However, due to the fixed installation position of the stirring rods, the stirring range is relatively limited and the stirring effect is poor, which is not conducive to use.
