DMH Project Introduction
Starch milk adjustment: Starch milk from starch workshop is adjusted to DS=28-32%, appropriate PH and temp. Or mix the dry starch and water, then adjust to reach the above conditions into the next section.
Liquefaction: Starch milk is liqueficated with the jet cooker and the aid of liquefaction enzyme. Two times of ejection are needed to get the better liquefaction effect. After liquefaction, the material is sent to the flash tank for cooling, and then to the next section.
saccharification: The liquefied syrup is sent to the saccharification tank. The reaction is carried out with the aid of enzyme. After a certain time of reaction, the desired DE value is reached. After that, the glucose is sent to the flash tank for cooling, then to next section.
Filtration and decolorization: Take the filter to remove the protein and other impurities from the glucose, then enters the decolorization filtration system. Decolorization requires activated carbon at the appropriate temp. After decolorization, the activated carbon will be removed by the filter. Then the filtered glucose is sent to the next section.
Continuous ion exchange: The glucose enters the continuous ion exchange system to remove the mixed impurity ions in the glucose through the cation and anion resin, so as to obtain the pure and high quality glucose.
Evaporation: The glucose is filtered through the safety filter and fed into the evaporator system for concentration to obtain the desired DS value.
Crystallization: After sterilization, the qualified glucose is fed into the crystallizer system. Maintain the appropriate time, conduct the crystallization by cooling according to the cooling curve, and then send the glucose crystal to the separation section.
Separation: The mother liquor is separated from the crystal by the high speed centrifugation. Part of the mother liquor returns to the decolorization section. Part of the mother liquor is sent to the liquid glucose production or sold directly. The separated qualified glucose crystals are sent to the drying section for drying.
Drying: Both air dryer system or fluidized bed dryer system can be used as the drying system of the crystalline dextrose for drying to obtain the qualified DMH product with moisture content less than 10%.
