[0002] Compared with the commonly used soybean oligosaccharides, fructo-oligosaccharides, isomalto-oligosaccharides, etc., xylooligosaccharides have unique advantages. They can selectively promote the proliferation activity of intestinal bifidobacteria.

[0003] In the process of processing and producing xylooligosaccharides, it is necessary to heat and evaporate the xylooligosaccharides and liquid to concentrate them so that the xylooligosaccharides are at a suitable concentration for subsequent processing.

[0004] In the process of concentrating xylooligosaccharides, the xylooligosaccharide liquid is input into a concentrating device for evaporation and concentration.

In the prior art, stirring is only performed by a stirring rod in a central position, and the stirring direction is consistent, causing the liquid to rotate with the stirring rod, and the stirring and mixing effect is not good. Therefore, we propose a concentrating device for preparing xylooligosaccharides. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model embodiment discloses a concentrating device for preparing xylooligosaccharides.

[0023] According to the attached Figure 1-4 As shown, it includes a reactor 1, a sealing cover 101 and a main stirring rod 301. The sealing cover 101 is installed on the reactor 1 by bolts. The main stirring rod 301 is rotatably connected to the inside of the reactor 1. When the main stirring rod 301 rotates, the xylo-oligosaccharide raw material in the reactor 1 is driven to stir;

[0024] Two connecting rods 4 are fixedly connected to the outer wall of the main stirring rod 301. The connecting rods 4 are distributed at both ends of the main stirring rod 301. The ends of the connecting rods 4 are fixedly connected to contact rods 401. The contact rods 401 are in contact with the inner wall of the reactor 1. When the main stirring rod 301 rotates, the connecting rods 4 are driven to rotate. At this time, the connecting rods 4 drive the contact rods 401 fixedly connected thereto to rotate. At this time, the contact rods 401 scrape off the adhesion on the inner wall of the reactor 1 to avoid the adhesion of raw materials leading to crystallization and affecting the concentration. The connecting rods 4 are provided with:

[0025] The stirring unit includes a slave stirring rod 5, which is rotatably connected to the inner wall of the connecting rod 4. The stirring unit stirs and mixes the oligoxylose preparation raw materials in the reactor 1 evenly by rotating the slave stirring rod 5. Under the rotation of the main stirring rod 301, the first gear 501 rotates to drive the slave stirring rod 5 to rotate on the connecting rod 4. The rotation direction and rotation position of the slave stirring rod 5 are different from those of the main stirring rod 301, resulting in two stirring forces in the reactor 1, which is convenient for mixing the raw materials.

[0026] A feed port 102 is provided at the top end surface of the sealing cover 101 , and a discharge port 103 is provided at the bottom end surface of the reactor 1 . Raw materials are added through the feed port 102 , and concentrated raw materials are discharged through the discharge port 103 .

[0027] A connecting shaft 3 is rotatably connected to the inner wall of the sealing cover 101 , one end of the connecting shaft 3 is connected to the main stirring rod 301 , and the main stirring rod 301 is driven to rotate by the rotation of the connecting shaft 3 .

[0028] The other end of the connecting shaft 3 is connected to a motor 201, and the top end surface of the sealing cover 101 is fixedly connected to a support base 2. The motor 201 is installed on the support base 2. Under the action of the motor 201, the main stirring rod 301 is driven to rotate. Under the rotation of the main stirring rod 301, the oligoxylose raw material in the reactor 1 is stirred.

[0029] The top end surface of the upper connecting rod 4 is rotatably connected with the first gear 501 and the second gear 502. When the connecting rod 4 rotates, the first gear 501 and the second gear 502 on the connecting rod 4 rotate accordingly.

[0030] The first gear 501 is meshed with the second gear 502 , and the outer peripheral wall of the stirring rod 5 is inserted into the inner wall of the first gear 501 .

[0031] The outer peripheral wall of the second gear 502 is meshed with a fixed gear 503, and the fixed gear 503 is fixedly connected to the inner wall of the reactor 1. When the second gear 502 follows the rotation of the connecting rod 4, the second gear 502 rotates relative to the fixed gear 503. At this time, the fixed gear 503 drives the second gear 502 to rotate, and at this time, the second gear 502 drives the first gear 501 to rotate;

[0032] At this time, the rotation of the first gear 501 drives the slave stirring rod 5 to rotate on the connecting rod 4. The rotation direction and rotation position of the slave stirring rod 5 are different from those of the main stirring rod 301, resulting in two stirring forces in the reactor 1, which is convenient for mixing the raw materials.

[0033] Working principle: First, the raw materials are added through the feed port 102, and the raw materials are heated, evaporated and concentrated through the reactor 1. At the same time, the motor 201 is started to drive the main stirring rod 301 to rotate. Under the rotation of the main stirring rod 301, the xylooligosaccharide raw materials in the reactor 1 are stirred;

[0034] The main stirring rod 301 rotates, driving the connecting rod 4 to rotate. At this time, the connecting rod 4 drives the contact rod 401 fixedly connected thereto to rotate. At this time, the contact rod 401 scrapes off the adhesion on the inner wall of the reactor 1 to avoid the adhesion of raw materials leading to crystallization and affecting the concentration.

[0035] When the connecting rod 4 rotates, the first gear 501 and the second gear 502 on the connecting rod 4 rotate accordingly. When the second gear 502 rotates, the second gear 502 rotates relative to the fixed gear 503. At this time, the fixed gear 503 drives the second gear 502 to rotate. At this time, the second gear 502 drives the first gear 501 to rotate.

[0036] At this time, the rotation of the first gear 501 drives the slave stirring rod 5 to rotate on the connecting rod 4. The rotation direction and rotation position of the slave stirring rod 5 are different from those of the main stirring rod 301, resulting in two stirring forces in the reactor 1, which is convenient for mixing the raw materials.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
