CONTINUOUS PROCESS FOR THE PRODUCTION OF A CORN FIBER PRODUCT WITH A HIGH CONTENT OF DIETARY FIBERS

摘要

An improved process is disclosed for producing corn fiber having a high total dietary fiber content and a reduced SO2 content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-milling process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content. This fiber fraction is then passed into a first centrifugal paddle screen followed by two stages of washing, including washing with a second centrifugal paddle screen. Fiber from the second centrifugal paddle screen, which is optionally pressed to remove water that contains dissolved SO2, is dried to make the final product. Heated water can be used during washing to remove additional SO2 more effectively.
