Process description

(1) Starch milk adjustment: Starch milk coming from starch plant is adjusted to DS28-32% and proper PH and temperature. And adding CaCl2 to reach the condition for next section.

(2) Liquefaction:Starch milk is sent to buffer tank then liquefied by jet cooker with the aid of enzyme. After that, the material is sent to the liquefaction column for the reaction. Then send to another jet cooker for the further reaction. After cooling and PH adjusting, it is sent to the filtration section.

3) Filtration and decoloring: Maltodextrin is cleaned by removing the protein and other foreign items with filter. Active carbon is needed for decoloring at proper temperature. After decoloring, the AC will be removed by filter. And then the material will be sent to the next section.

(4) Ion exchange: Tiny foreign items and bad odor is removed via ion exchanger. This equipment is used for high quality product.

(5) Evaporation: The maltodextrin is totally cleaned through safety filter then sent to evaporator for concentrating to reach the required DS.

(6) Drying: After concentration, the qualified maltodextrin liquid is sent to the spray dryer system for drying to get the required maltodextrin powder.
