ABSTRACT:
A new process and apparatus efficiently dewater aqueous solids residual after fermentation and distillation, such as corn stillage. The feed stream of aqueous solids slurry is fractionated into two or more substreams in such a way that one of the substreams contains predominately heavy particulate solids and has substantially improved free-draining characteristics. A second substream contains lighter particles, entrained fines of the heavy particles, and a major portion of the liquid from the feed stream. The free-draining substream is dewatered using a device such as a screen centrifuge or a screw press, both of which produce a cake of relatively high solids content. The remaining liquid from the feed stream is concentrated in an evaporator, before being mixed with the dewatered solids which may be dried to produce an animal feed.
