To provide an apparatus for purifying sugar syrup to give purified sugar syrup having stabilized purity by a changeover operation with a small number of plates while suppressing the proliferation of microorganisms and provide a method for the purification of sugar syrup by using the apparatus.
The sugar syrup purification apparatus has (1) a sugar syrup purification column divided with partition plates into an upper chamber (C chamber) containing a cation exchange resin, a middle chamber (A chamber) containing an anion exchange resin and a lower chamber (MB chamber) containing a mixture of a cation exchange resin and an anion exchange resin, wherein the partition plate between the upper chamber (C chamber) and the middle chamber (A chamber) allows the passage of a fluid and inhibits the passage of ion exchange resins, the partition plate between the middle chamber (A chamber) and the lower chamber (MB chamber) inhibits the passage of fluid and ion exchange resin, and the middle chamber (A chamber) is made to communicate with the lower chamber (MB chamber) through a pipe to transfer the liquid flowed from the A chamber to the MB chamber and (2) a regeneration column receiving the cation exchange resin of the upper chamber (C chamber) and the mixed resin of the lower chamber (MB chamber), separating the cation exchange resin from the anion exchange resin and regenerating the cation exchange resin. The invention further provides a method for the purification of the sugar syrup by the purification apparatus.
