Maltitol 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 maltose 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 maltose, 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 maltose is sent to the next section.
Continuous ion exchange: The maltose enters the continuous ion exchange system to remove the mixed impurity ions in the maltose through the cation and anion resin, so as to obtain the pure and high quality maltose.
Hydrogenation reaction: After burdening, the qualified maltose enters the reactor, and the high pres. Hydrogen is added for the hydrogenation reaction. Through the reaction, the maltose is converted to the crude maltitol. After cooling by flash, the crude maltitol is sent to the sedimentation tank.
Precipitation and filtration: After precipitation, the crude maltitol passes through the filter to recover the small amount of nickel catalyst remaining in the maltitol, then reuse to the front section. The filtered crude maltitol goes into the refinery section.
Decolorization/filtration: The crude maltitol enters the decolorization and filtration system. Decolorization requires activated carbon at the appropriate temp. After decolorization, the activated carbon will be removed by the filter. Then the filtered maltitol is sent to the next section.
Continuous ion exchange: The maltitol enters the continuous ion exchange system to remove the mixed impurity ions in the maltitol through the cation and anion resin, so as to obtain the pure and high quality maltitol.
Evaporation: The refined maltitol is filtered through the safety filter and fed into the evaporator system for concentration to obtain the desired DS value of the maltitol product.
