Línea de producción de sorbitol de acero inoxidable de suministro directo de fábrica

Sorbitol Project Introduction

The commercial starch is sent to the dissolving tank and dissolved by adding water. Then, enters the slurry mixing tank, through online detection and control, adjust the DS, PH value and enzyme amount of the starch milk, and then enters the automatic liquefaction system. Adopt two times ejection, twice flashing, maintain the appropriate temp. and a certain time, to ensure the best liquefaction effect. After liquefaction, through PH adjustment and enzyme addition, the syrup is sent to the saccharification system. By controlling the amount of enzyme and saccharification time, the DE or DX value required by the final product is reached, and the syrup enters the filtration stage to remove the less protein and other impurities mixed in the product. After filtration, the liquid syrup goes through decoloring, filtering and continuous ion exchange system to remove the colored impurities and impurity ions of the syrup, so that the syrup can achieve the purpose of refining and purification. After being concentrated by evaporator, it enters the high pressure hydrogenation reactor for hydrogenation reaction. After the reaction is completed, a small amount of nickel catalyst mixed in the sorbitol solution is filtered for reuse. The impurities and ions in the sorbitol solution are removed through decolorization, filtration and continuous ion exchange system, so that the sorbitol solution can achieve the purpose of refining and purification. The qualified sorbitol was obtained after concentration by evaporator.
