Process of crystalline dextrose


(1) Starch milk blending: Adjusting the starch milk concentrate which ranges from 31% to 34% by adding certain water. At the same time, keep the material appropriate temperature and pH value, and then ass a certain amount of liquefied enzyme.

(2) Liquefaction: pumping the adjusted starch milk to the high pressure injector and maintaining for certain time, which can ensure that the starch is adequately hydrolyzed and liquefied.

(3) Saccharification: After adjusting the temperature and pH value the liquefied material is pumped to the saccharification tank. Under the action of saccharification enzyme, keep the reaction for a certain time to obtain saccharification liquid whose DE value matches the requirement.

(4) Filtration and Decolorization: Separating the impurities such as protein by filter, and then heat the material and it to the Decolorization tank in which there is active carbon that can decolorize the material. At last pump the mixture to the filter by which to remove the carbon.

(5) Ion exchange: Remove the salt and organic existing in the glucose by the ion exchange resin for its exchange property to specific ion and adsorption property to the organic. Through this treatment, high quality glucose can be obtained.

(6) Evaporation: Increase the concentration of glucose by evaporation.

(7) Crystallization: Sterilizing the concentrated glucose and then transporting it to a crystallizer. Add a certain amount of crystal seeds into the crystallizer and maintain a certain time. In the process, control the crystallization temperature to make the glucose molecules crystallize out of the solution.

(8) Separation: Using the centrifuge to separate the glucose crystal and glucose solution.

(9) Drying: Transport the wet glucose crystal to the dyer, in which the material will be dried according to the moisture requirement.
