Fructose Project Introduction

Starch milk adjustment: Starch milk adjustment with appropriate DS value (DS=28%-32%), PH value, and temperature. Also, dry starch can be mixed with water to get starch milk. Then after adjustment, it is sent to the next step for further processing.

Liquefaction: A jet cooker is used for the liquefaction process. Two times ejection is used to get better liquefaction results. After liquefaction, the material goes to a flash tank for cooling, and the material goes to the saccharification stage.

Saccharification: Saccharification is used to reach desired DE value. The enzyme aid in carrying out the reaction. After maintaining a specific time, liquefied syrup reaches the desired DE value. Then the glucose goes to a flash tank for cooling. After cooling, the glucose goes to the next stage for further impurities removal.

Filtration and decolorization: The produced glucose has protein and other impurities that need removal. Also, some colored ion pigments need to be removed in this stage before moving to the next section. Filtration removes the protein and other impurities. Then the activated carbon is used for decolorization. After that, the activated carbon will be removed by filtration. Then the glucose goes to the next steps for further processing.

Continuous ion exchange: The filtered glues still have some mixed ion impurities that the ion exchange system needs to remove based on their chemical attraction behavior. The ion exchange system is filled with resin. The resin has two parts cation and anion. The mixed ion is attracted by cation and anion based on their principle. In this way, the glucose reaches a high level of purity. Then the glucose goes to the next stage.

Evaporation: The glucose needs to reach desired DS value. Evaporation concentrates the glucose to get the suitable DE level. Then the glucose with appropriate DE goes to the next section.

Isomerization: The glucose with suitable DS and PH values goes to the isomerization system. Then glucose changes the internal structure and changes to 42% fructose. The isomerization action works on glucose to change into fructose at 42%. Then fructose 42% goes to the next section.

Decolorization/filtration: The 42% fructose needs to filter then it goes to the decolorization system. Activated carbon is used in the decolorization system. Then the activated carbon is removed by the filter. Then the filtered 42% fructose goes to the next stage.

Continuous ion exchange: Ion exchange system remove the mixed ion impurities based on their chemical attraction principle. The ion exchange system is filled with a resin that contains anion and cation. After the ion exchange process, the fructose reaches a high quality of 42%.

Evaporation: The 42% fructose needs to reach desired DS value. Evaporation concentrates the fructose 42% to get desired DS value. Then the material goes to the next stage.

Chromatography separation and 55% fructose mixing: High purity fructose mixed 42% to obtain the 55% fructose. The chromatography separation work on the glucose and fructose 42% to get 55% fructose. After chromatography separation, the 55% fructose goes to the next stage for further processing.

Decolorization/filtration: Filtration works on 55% fructose to remove impurities. Then the activated carbon works for the decolorization system. After decolorization, the activated carbon will be removed by the filter. The decolorization system maintains the appropriate temperature at processing time. Then the 55% fructose is sent to the next stage.

Mixed bed ion exchange: The 55% fructose has mixed impurity ions. The Mixed bed ion exchange system removes the impurities, and 55% fructose reaches a high purity level.

Evaporation: Evaporation concentrates the refined 55% fructose to obtain desired DS value. After evaporation, the suitable DS value product will be obtained.
