The liquefaction process is convert the starch into liquid dextrin. The material will be sprayed at high temperature by jet cooker . With the aid of amylase and steam , the starch will be converted into liquid dextrin quickly. The mixing process is mixing the raw material such as corn powder( or rice powder or refined starch powder) and water to get the right density slurry. Then add the amylase and keep on the temperature for particular time to make powder absorbing enough water .
