一种基于活性炭脱色的精制糖加工方法
摘要：
一种基于活性炭脱色的精制糖加工方法，其操作步骤为：(1)溶解：用水将原糖溶解至60～65°Bx，得到原糖回溶糖浆；(2)陶瓷膜过滤：利用陶瓷膜组件对原糖回溶糖浆进行过滤，得到陶瓷膜透过液；(3)活性炭预脱色：向陶瓷膜透过液中加入活性炭，充分吸附后得到活性炭预脱色糖浆；(4)离子交换树脂脱色除盐：利用第一离子交换树脂对活性炭预脱色糖浆进行脱色，得到第一渗透液；再利用第二离子交换树脂对第一渗透液进行脱盐，得到的渗透液即为精糖浆；(5)蒸发、结晶：精糖浆经蒸发浓缩和煮糖结晶后得到结晶果糖。
摘要（英）：

The invention relates to a refined sugar processing method based on activated carbon decolorization. The refined sugar processing method comprises the following operation steps: (1) dissolving: dissolving raw sugar to 60-65 degrees Bx with water to obtain raw sugar resoluble syrup; (2) ceramic membrane filtration: filtering the raw sugar resoluble syrup by utilizing a ceramic membrane module to obtain a ceramic membrane penetrating liquid; (3) activated carbon pre-decolorization: adding activated carbon in the ceramic membrane penetrating liquid and obtaining activated carbon pre-decolorization syrup after full adsorption; (4) ion exchange resin decolorization and desalting: decolorizing the activated carbon pre-decolorization syrup by utilizing first ion exchange resin to obtain a first penetrating liquid; then desalting the first penetrating liquid by utilizing second ion exchange resin, wherein the obtained penetrating liquid is refined syrup; (5) evaporation and crystallization: performing evaporation, concentration and boiled sugar crystallization on the refined syrup to obtain crystalline fructose.
