Abstract:
A sugar solution deionization system, comprising:an ion exchange column arranged so as to allow the sugar solution to pass therethrough, the ion exchange column comprising: a strongly acidic cation exchange resin; and a basic anion exchange resin; a first port connected adjacent to the basic anion ion exchange resin; a second port connected adjacent to the strongly acidic cation exchange resin; a third port, disposed proximal to an interface layer formed by the strongly acidic cation resin and the basic anion exchange resin; a controller, operatively connected to at least the first port and the second port, and arranged to control at least the flow of an alkali regenerating agent and an acid regenerating agent through said first port and said second port, such that said alkali regenerating agent is provided through said first port and first comes in contact with said basic anion exchange resin and then contacts said strongly acidic cation exchange resin, and said acid regenerating agent is provided through said second port and first comes in contact with said strongly acidic cation exchange resin.
