Sorbitol Project Introduction
The dissolving tank receives the commercial starch, which is then added water to dissolve. After that, the starch milk enters a slurry mixing tank where its DS, PH value, and enzyme content are adjusted by online detection and control before moving on to an automatic liquefaction system. To achieve the finest liquefaction effect, use two-times ejection, two-times flashing, right temperature, and a specific time. Syrup is introduced to the saccharification system after liquefaction through PH adjustment and enzyme addition. When the DE or DX value required by the end product is obtained by regulating the amount of enzyme and saccharification time, the syrup enters the filtration stage to purge the product of any remaining protein and other contaminants. Following filtration, the liquid syrup undergoes decolorization, filtering, and a continuous ion exchange system to remove coloured impurities and impurity ions, enabling the syrup to fulfil its refining and purifying objectives. It enters the high pressure hydrogenation reactor for the hydrogenation reaction after being concentrated by the evaporator. A small amount of the nickel catalyst added to the sorbitol solution is filtered after the reaction is finished and used again. Decolorization, filtration, and a continuous ion exchange system are used to remove contaminants and ions from the sorbitol solution so that it can fulfil its refining and purifying objectives. After concentration using an evaporator, the appropriate sorbitol was achieved.
