1. A method of evaporating moisture from one or more process streams derived from a beer in a biorefinery, wherein the method comprises:
a) recovering at least one recovered solids stream from the one or more process streams derived from a beer, wherein the at least one recovered solids stream has a moisture content of 90% or less by weight and a suspended solids content of at least 8% by weight on an as-is basis;
b) exposing at least a portion of the at least one recovered solids stream to an evaporator system to remove moisture from the at least a portion of at least one recovered solids stream and form a concentrated, recovered solids stream having a higher suspended solids content on an as-is basis than the at least one recovered solids stream; and
c) drying at least a portion of the concentrated, recovered solids stream in a dryer system to form a dried product.
