Sorbitol Project Introduction
Starch milk adjustment: Starch milk from the starch workshop has its DS=28-32%, PH, and temperature regulated. Alternately, mix dry starch and water, then switch to the conditions listed above in the section after.
Liquefaction: A jet cooker and a liquefaction enzyme are used to liquefy starch milk. It takes two ejections to achieve the best liquefaction effect. After cooling in the flash tank following liquefaction, the material is transferred to the following step.
Saccharification: The syrup is brought to the saccharification tank after being liquefied. Enzymes carry out the process. After a set reaction period, the required DE value is reached. After the flash tank has cooled, the glucose is moved to the following stage.
Filtration and decolorization: After taking the filter to remove the protein and other impurities from the glucose, enter the decolorization filtering system. Decolorization requires the application of activated carbon at the correct temperature. After decolorization, the filter will get rid of the activated carbon. The filtered glucose is delivered to the next stage.
Continuous ion exchange: The glucose enters a constant ion exchange system where the mixed impurity ions are eliminated using cation and anion resin to obtain pure and high-quality glucose.
Hydrogenation reaction: After burdening, the qualifying syrup is added to the reactor, and high-pressure hydrogen is added to initiate the hydrogenation reaction. The procedure converts glucose to a rudimentary form of sorbitol. After flash cooling, the crude sorbitol is transferred to the sedimentation tank.
Precipitation and filtration: After precipitation, the crude sorbitol is filtered to eliminate any remaining nickel catalyst before being employed in the front part again. The filtered raw sorbitol is delivered to the refining portion.
Decolorization/filtration: The raw sorbitol is fed into the filtration and color removal system. Decolorization requires the application of activated carbon at the correct temperature. After decolorization, the filter will get rid of the activated carbon. The filtered sorbitol is given to the following component.
Continuous ion exchange: Sorbitol enters a continuous ion exchange system where the mixed impurity ions are eliminated using cation and anion resin to produce pure and high-quality sorbitol.
Evaporation: The refined sorbitol is concentrated after being delivered into the evaporator system and passed through the safety filter to obtain the required DS value for the sorbitol product.
