Équipement de fabrication de sorbitol efficace à haut rendement économique ISO

Sorbitol Project Introduction

Starch milk adjustment: The DS=28-32%, PH, and temperature of starch milk from the starch workshop are adjusted. Alternately, combine dry starch and water, then make adjustments to obtain the aforementioned conditions in the following step.

Liquefaction: With the help of the jet cooker and a liquefaction enzyme, starch milk is liquefied. To achieve the best liquefaction effect, two ejections are necessary. The substance is liquefied, then moved to the next step after cooling in the flash tank.

saccharification: The saccharification tank receives the liquidised syrup. An enzyme is used to carry out the process. The target DE value is attained after a specific amount of reaction time. The glucose is subsequently sent to the following step after cooling in the flash tank.

Filtration and decolorization: Enter the decolorization filtering system after taking the filter to filter out the protein and other contaminants from the glucose. Activated carbon must be used for decolorization at the proper temperature. The filter will eliminate the activated carbon after decolorization. The following stage receives the filtered glucose.

Continuous ion exchange: To obtain pure and high-quality glucose, the glucose enters a continuous ion exchange system where the mixed impurity ions are removed using cation and anion resin.

Hydrogenation reaction: Once the qualified syrup has been supplied, the reactor is filled with high pressure hydrogen, which is then added to initiate the hydrogenation procedure. The glucose is changed into crude sorbitol during the process. The flash-cooled crude sorbitol is then transferred to the sedimentation tank.

Precipitation and filtration: Following precipitating, the unfiltered crude sorbitol is reused in the front portion after being filtered to recover the little bit of nickel catalyst that is still present. The refining portion receives the filtered crude sorbitol.

Decolorization/filtration: The system for decolorization and filtration receives the raw sorbitol. Activated carbon at the right temperature is necessary for decolorization. The filter will remove the activated carbon after it has been decolored. The filtered sorbitol is then transferred to the following stage.

Continuous ion exchange: To obtain pure and high-quality sorbitol, the sorbitol enters a continuous ion exchange system where the mixed impurity ions are removed using cation and anion resin.

Evaporation: To achieve the appropriate DS value for the sorbitol product, the refined sorbitol is supplied into the evaporator system after being filtered by the safety filter.
