TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The suspended solids is less than 10 wt.% of total solid content. The total solid content is 68-72 wt.%. The one or more reduced suspended solids stream has total solid content comprising suspended solid and dissolved solid (30-90 wt.%), where the suspended solid comprises total solid content less than 25 wt.%. The one or more reduced suspended solid stream is clarified concentrated thin stillage comprising bio-oil in larger amount by volume, than bio-oil present in concentrated unclarified thin stillage. Preferred Method: The clarified concentrated thin stillage is subjected to mechanical processing, where the mechanical processing produces emulsion concentrate that is broken in emulsion breaking reaction to produce the bio-oil phase. The mechanical processing also produces solid stream and de-oiled clarified concentrated thin stillage product. The method further involves providing the de-oiled clarified concentrated thin stillage product to the one or more evaporators. The one or more reduced suspended solids stream is molasses product having total solid content not less than 45 wt.%, where the suspended solids comprise less than 25-0 wt.% of the total solids content. The clarified thin stillage is substantially provided to the thin stillage product. The method further involves combining at least one portion of one or more reduced suspended solid streams with wet cake to produce wet cake product containing reduced suspended solids, drying the wet cake product to produce distillers dried grain, providing at least one portion of one or more reduced suspended solid streams to dryer for producing distillers dried grain solubles, and drying the fine suspended solid stream to produce dry distillers solubles. The thin stillage product is produced from low water extractable non-starch polysaccharide-containing plant biomass. The molasses comprises bio-oil 2-3 times greater than concentrated thin stillage, where the molasses has total solids (65-75 wt.%) and bio-oil (8-12 vol.%). The molasses product has total solids (65-75 wt.%) and bio-oil (8-12 wt.%) and it is sold in combination with wet cake and/or dried.
