1.1.　　 IntroductionIntroduction Ion exchange resins (IER) have been employed in the sugar refin

ery process for the purpose of decolorization and demineralization

(deashing) of sugar liquor. Compared to the remelting of white sug

ar, higher decolorization rate and extremely high sugar yield can be

obtained by the direct demineralization of clear liquor or fine liquor.

Organo has developed an efficient IER system the “SUPER FINE L

IQUOR SYSTEM” (A-MB system), which consists of an anion exch

ange resin tower and a mixed bed tower of anion exchange resin a

nd cation exchange resins. This system has been applied to many

sugar refinery factories in Japan and has an excellent reputation for

the high quality.
