The invention relates to a method of dewatering corn gluten stream wherein coagulant is add to the corn gluten stream of the corn wet milling process. The method of dewatering corn gluten uses an effective amount of a coagulant of one or more anionic polymers, the anionic polymers comprising one or more anionic monomers. The method further includes a process for separating the water from the gluten using a solids/liquids filtration device.

Additives for the improved dewatering of corn gluten

A method dewatering thin stillage process streams generated in the processing of grain to ethanol comprising adding to the process streams an effective flocculating amount of an anionic copolymer comprising acrylic acid sodium salt, methacrylic acid sodium salt or 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt to form a mixture of water and flocculated solids; and separating the water from the flocculated solids using a dewatering device.
