Problems solved by technology

[0005] When the fixed bed intermittently separates fructo-oligosaccharides and polyfructosaccharides, only a small amount of resin in the mass transfer area is working in the entire bed, and most of the resin is in an inactive idle and waiting state, which has the disadvantage of low utilization rate of the resin; at the same time A large amount of material or regenerant needs to pass through or soak the deactivated resin, causing pollution to the resin
In addition, the operation period is long, there are many connected pipelines and valves, and the operation is cumbersome; the resin utilization efficiency is low, resulting in a large resin bed and a large amount of washing water required for the separation process; not only the area is large, but the product purity, concentration and yield Low, and the discharge of acid and alkali waste liquid is large, which seriously pollutes the environment

Abstract

The invention provides a continuous chromatographic separation and purification system for separating sugar in inulin. A plurality of separation units which are connected together in series are driven by a turntable to rotate, and when the turntable rotates a circle, under the action of cation exchange resin filled in the separation units, fructo-oligosaccharide flows out of an elution area, polyfructose flows out of a separation area, and recycled water flows out of a concentration area. In such a manner, an inulin solution is separated and purified, so that links of exchange, washing, recycling, leaching and the like in an original fixed bed are integrated in the same system to achieve a better separation and purification effect.

Description

technical field [0001] The invention relates to the technical field of liquid separation and purification, in particular to a continuous chromatographic separation and purification system for separating sugar in inulin. Background technique [0002] Inulin is a fructan mixture in which fructose molecules are connected by β-(2-1) glycosidic bonds and end with a glucose molecule. Currently, inulin is mainly derived from Jerusalem artichoke and chicory. The degree of polymerization of fructose units in natural inulin is usually 2-60, with an average degree of polymerization of about 10. [0003] Fructans with a polymerization degree of 2-9 in inulin are commonly called fructo-oligosaccharides, and the content of fructo-oligosaccharides in inulin is generally 5-35%. Fructose-oligosaccharide is a natural active substance, a new type of sweetener with health functions such as regulating intestinal flora, multiplying bifidobacteria, maintaining the balance of intestinal flora, pr...
