Organo Corporation Liquid Sugar Refining Process Ion Exchange Resin Demineralization System JUNE 16, 2011 Organo THAILAND CO.
Organo Corporation 1. Introduction Ion exchange resins (IER) have been employed in the sugar refinery process for the purpose of decolorization and demineralization (deashing) of sugar liquor. Compared to the remelting of white sugar, 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 LIQUOR SYSTEM (A-MB system), which consists of an anion exchange resin tower and a mixed bed tower of anion exchange resin and cation exchange resins. This system has been applied to many sugar refinery factories in Japan and has an excellent reputation for the high quality.
Organo Corporation Low cost Ingredient of sauce (demineralization) (Hydrolyzed sugar syrup) 2. Liquid Sugar Products in Japan Ion exchange resin refined liquid sugar Sucrose type Liquid Sugar High quality Large scale production Molasses type Liquid Sugar Distinct flavor Nongenetically modified (compared to isomerized sugar made from cornstarch) Invert Syrup Remelt liquid sugar granulated sugar Quality depends on granulated sugar and water. Small scale production
