Erythritol Project Introduction
Starch milk adjustment: Starch milk from starch workshop is adjusted to DS=28-32%, appropriate PH and temp. Or mix the dry starch and water, then adjust to reach the above conditions into the next section.
Liquefaction: Starch milk is liqueficated with the jet cooker and the aid of liquefaction enzyme. Two times of ejection are needed to get the better liquefaction effect. After liquefaction, the material is sent to the flash tank for cooling, and then to the next section.
saccharification: The liquefied syrup is sent to the saccharification tank. The reaction is carried out with the aid of enzyme. After a certain time of reaction, the desired DE value is reached. After that, the glucose is sent to the flash tank for cooling, then to next section.
Filtration and decolorization: Take the filter to remove the protein and other impurities from the glucose, then enters the decolorization filtration system. Decolorization requires activated carbon at the appropriate temp. After decolorization, the activated carbon will be removed by the filter. Then the filtered glucose is sent to the next section.
Continuous ion exchange: The glucose enters the continuous ion exchange system to remove the mixed impurity ions in the glucose through the cation and anion resin, so as to obtain the pure and high quality glucose.
Fermentation: Qualified glucose enters the fermentation system, through the addition of cultivated seed, as well as the required nutrients, at a suitable temperature, maintain a certain time for the fermentation.
Evaporation & crystallization: The fermented mash is concentrated by the evaporator system to obtain the appropriate DS value for the crystallizer. Through the certain time crystallization, the erythritol crystal is obtained.
Separation and drying: The erythritol crystals after crystallization, separated by the centrifuge to obtain the qualified erythritol crystals and mother liquor. After drying, qualified erythritol products were obtained.
