Description

Technical Field

[0001] The utility model relates to the technical field of isomaltooligosaccharide production, and particularly relates to an ion exchange device for isomaltooligosaccharide. Background Art

[0002] Isomaltooligosaccharide (IMO), also known as isomalto-oligosaccharide, isomalto-oligomer, branched oligosaccharide, etc., is a kind of starch sugar, and its main components are isomaltose, panose, isomaltotriose and oligosaccharides with four or more sugar units in which glucose molecules are linked by α-1,6 glycosidic bonds. As a functional oligosaccharide, isomaltooligosaccharide has wide applications in the fields of food, health products, etc. During the production process of isomaltooligosaccharide, raw materials and intermediate products may contain various impurities, such as inorganic salts, organic small molecules, etc. These impurities will affect the taste, color and stability of the product. The ion exchange device can selectively adsorb these impurities through the ion exchange resin inside it, thereby significantly improving the purity of isomaltooligosaccharide. The ion exchange resin has different affinities for different ions and molecules, and can selectively remove or retain specific components according to needs. In the production of isomaltooligosaccharide, the ion exchange device can remove unnecessary impurities while retaining the target product isomaltooligosaccharide, ensuring the purity and quality of the product.

[0003] Chinese Utility Model Patent Publication No. CN219441707U discloses an ion exchange device for erythritol products, which includes a tank body. A liquid inlet seat is fixedly installed at the bottom side of the tank body and a liquid inlet pipe is assembled at its input end. A liquid discharge seat is fixedly installed at the top side of the tank body and a liquid discharge pipe is assembled at its output end. A base is fixedly installed inside the tank body, a receiving plate is fixedly welded in the base, a uniformly distributed pressing plate is placed above the receiving plate, and a resin layer is pressed between adjacent pressing plates and between them and the receiving plate. This device uses the method of feeding liquid from the bottom side for liquid infusion, so that the inside of the tank body can always be filled with liquid, and the newly input liquid will squeeze out the old liquid from the liquid discharge seat and the liquid discharge pipe. However, this device has a single-tank structure and the liquid flows from bottom to top, with limited flow paths, which may still result in poor ion exchange effect. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an ion exchange device for isomaltooligosaccharide, which increases the liquid flow path and improves the ion exchange effect.

[0005] The isomaltooligosaccharide ion exchange device described in the utility model includes a housing. Inside the housing, a circulation pipe and a fixed ring plate are vertically arranged. The lower end and the upper end of the circulation pipe are respectively communicated with a liquid inlet pipe and a liquid outlet pipe that penetrate the bottom and the top of the housing. The fixed ring plate is sleeved outside the circulation pipe, and a number of liquid holes are distributed on the walls of both the circulation pipe and the fixed ring plate. The circulation pipe and the fixed ring plate divide the inner cavity of the housing into a flow cavity, an ion exchange cavity, and a liquid leakage cavity from the inside to the outside. A flow cavity is formed inside the circulation pipe, an ion exchange cavity is formed between the circulation pipe and the fixed ring plate, and a liquid leakage cavity is formed between the fixed ring plate and the inner wall of the housing. A first baffle is arranged in the housing through the flow cavity and the ion exchange cavity, and a second baffle is arranged through the ion exchange cavity and the liquid leakage cavity. There are at least 2 first baffles, and the second baffle is arranged between two adjacent first baffles. The flow cavity is divided into several flow sub-cavities by the first baffle, the ion exchange cavity is divided into several ion exchange sub-cavities by the first baffle and the second baffle, the ion exchange sub-cavities are filled with resin, and the liquid leakage cavity is divided into several liquid leakage sub-cavities by the second baffle.

[0006] Preferably, a liquid return pipe is provided on the liquid leakage sub-cavity, and the liquid return pipe is connected to the liquid outlet pipe. If the liquid ions detected in the liquid outlet pipe are unqualified, they will be returned to the liquid leakage cavity through the liquid return pipe and then enter the ion exchange cavity for ion exchange.

[0007] Preferably, there are 3 first baffles and 2 second baffles.

[0008] Preferably, a flow regulating valve is provided on the liquid inlet pipe, and a stop valve is provided on the liquid outlet pipe. The flow rate of the liquid inlet pipe can be adjusted according to needs by adjusting the flow regulating valve.

[0009] Preferably, a liquid return valve is provided on the liquid return pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The liquid enters through the bottom liquid inlet pipe. After the liquid enters the flow sub-cavity, it flows into the ion exchange sub-cavity from the liquid holes on the wall of the circulation pipe, undergoes the first ion exchange, then enters the liquid leakage sub-cavity from the liquid holes on the wall of the fixed ring plate, and then enters the ion exchange sub-cavity of the second layer for the second ion exchange and then enters the second layer flow sub-cavity, and so on. The liquid flows upward layer by layer in the order of "flow sub-cavity - ion exchange sub-cavity - liquid leakage sub-cavity - ion exchange sub-cavity", and after multiple ion exchanges, it flows out from the flow sub-cavity of the topmost layer through the liquid outlet pipe. With such a setting, the flow path of the liquid is extended, the liquid contacts the ion exchange resin more fully, and the ion exchange effect is better. Brief Description of the Drawings
