SYSTEM AND METHOD FOR PROCESSING A STARCH-BASED MATERIAL

摘要

A method for processing a starch-based material is provided. The method includes liquefying the starch-based material in presence of a liquefaction enzyme to form a slurry and screening the slurry via one or more vibratory screening devices to form a first filtrate stream and a first filtration residue. The method includes mixing the first filtration residue with water to form an intermediate slurry and screening the intermediate slurry via one or more vibratory screening devices to form a second filtrate stream and a second filtration residue. The method also includes forming a fresh slurry using the second filtrate stream and optionally a portion of the first filtrate stream. The method also includes sterilizing and cooling first and second filtrate streams, and fermenting the cooled streams to form a fermentation product.
