Abstract
Official abstract text for this publication.
The present technology provide a method of dewatering whole stillage. The addition of a xylanase in combination with a pectinase results in a wet cake with a higher dry mass. The advantage here is less energy consumption while drying.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for dewatering a whole stillage in a fermentation process, the method comprising: (a) saccharifying a cellulosic material comprising corn with an enzyme composition; (b) fermenting the saccharified cellulosic material in a fermentation medium with a mixture of degrading enzymes comprising of a xylanase and a pectinase and with a fermenting organism to produce ethanol; (c) distilling the ethanol to form whole stillage; and (d) separating the whole stillage into thin stillage and wet cake, whereby more liquid phase is transferred to the thin stillage. 2. The method according to claim 1 , wherein the fermenting organism is selected from the group consisting of a bacteria, a yeast, and a fungi.
