Description

Technical Field

[0001] The utility model belongs to the separation technology of inulin oligosaccharide eluate, in particular to an inulin oligosaccharide eluate collecting device. Background Art

[0002] Inulin, also known as inulin, is one of the non-digestible oligosaccharides. It is widely distributed in the plant tissues of Jerusalem artichoke, chicory, dahlia, dandelion, and salsify of the Asteraceae family. It is a linear polysaccharide formed by the polymerization of D-fructofuranose through β-1,2 glycosidic bonds. It is slightly soluble in cold water, easily soluble in hot water, does not react with iodine to form a color, and has no reducing properties.

[0003] Among them, when inulin oligosaccharides are produced, they need to be made into powder oligosaccharide eluate, and then the macromolecules in the powder oligosaccharide eluate are separated by a separation membrane to retain the small molecules, thereby realizing the collection of inulin oligosaccharides.

[0004] Among them, when separating oligosaccharide eluate, the existing equipment often transports the oligosaccharide eluate into the separation chamber, and then uses the transport pressure to make small molecules pass through the separation membrane, while large molecules remain on the other side of the separation membrane. Although this method can effectively separate large molecules and small molecules, long-term use will cause large molecules to accumulate on the separation membrane, affecting the passage of small molecules. Utility Model Content

[0011] Preferably, the water storage tank is fixedly arranged on the top surface of the two separation chambers, and the water storage tank is connected with a main water outlet pipe, and the main water outlet pipe is perpendicular to and connected with the water spray pipes on both sides, so that water can be supplied to the separation chambers on both sides through one water storage tank.
