Erythritol Project Introduction
Starch milk adjustment: Starch milk needs to adjust with appropriate DS value, PH value, and temperature. Also, dry starch can be used as a raw material. Add the necessary amount of water with dry starch to make starch milk. The milk DS value must be between (DS=28%-32%). Then the adjusted starch milk goes to the next stage for further processing.
Liquefaction: Liquefaction adds enzymes and makes the starch slurry for further processing. The starch milk is sent to the jet cooker with and aid of the liquefaction enzyme. Two times of ejection works on the process to get a better liquefaction effect. After the liquefaction, the material needs cooling. The material is sent to a flash tank for cooling, and after cooling, the material is sent to the next stage for further processing.
Saccharification: Saccharification is used to get desired DE value. The syrup changes its internal structure and change to glucose with the aid of an enzyme. After a specific time, the desired DE value is obtained. Then the glucose goes to a flash tank for cooling. At last, the glucose goes to the next stage for filtration and decolorization system to get a higher impurity level.
Filtration and decolorization: The produced glucose has protein and other impurities. Also, have the colored ion that needs to remove to get the desired material. Filtration removes the protein and impurities. Then activated carbon is used to remove the color substances. After decolorization, the activated carbon will be removed by the filter. Then the filtered glucose goes to the next stage for the ion exchange system and further processing.
Continuous ion exchange: Filtered glucose has mixed impurities ion that did not remove in previous stages. The ion exchange system is filled with a resin that removes the mixed impurities ion from the glucose. The resin has cations and anions. These two ions attract mixed impurities ion based on their chemical principle. In this way, the glucose reaches a high purity level. Then the glucose goes to the next stage.
Fermentation: Fermentation is used to change the internal structure of glucose. The cultivated seed, nutrition, and suitable temperature are needed for the fermentation process. after a specific time, the fermented mash will be generated. Then the fermented material goes to the next stage for evaporation.
Evaporation & crystallization: Evaporator concentrates the fermented mash to get desired DS value for crystallization. Crystallization maintains the specific time and produces the erythritol crystal. Then the grown crystal goes to the next stage for crystal separation and drying.
Separation and drying: Separation is used to obtain qualified erythritol and mother liquor. Then the separated erythritol was sent to drying. After drying, suitable erythritol products will be produced.
