DAH 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 concentration through evaporator, the glucose reaches the concentration required for crystallization, and enters the crystallization system. According to the cooling curve of the crystallization system, the temperature of the glucose in the crystallizer is automatically adjusted. After maintaining for a certain time, the crystal enters the centrifuge for separation. After separation, the mother liquor is further used by returning to the previous process. The separated glucose is dissolved by adding water into the vacuum pan of DAH for evaporation and crystallization. Then the massecuite after vacuum pan is sent to the crystallizer and separated by the top-suspended centrifuge. The separated anhydrous glucose crystal is sent to the dryer for drying to obtain qualified DAH products.
