Abstract
The present disclosure relates to methods and systems for concentrating a solids stream recovered from one or more process streams derived from a beer in a biorefinery by exposing the recovered solids stream to an evaporator system to remove moisture therefrom and form a concentrated, recovered solids stream.
Claims20
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 on an as-is basis and a suspended solids content of at least 8% 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.
20) A biorefinery system configured to evaporate moisture from one or more process streams derived from a beer, wherein the system comprises:
- a) at least one separation system in fluid communication with the one or more process streams derived from the beer, wherein the separation system is configured to recover at least one recovered solids stream from the one or more process streams derived from the beer, wherein the at least one recovered solids stream has a moisture content of 90% or less on an as-is basis and a suspended solids content of at least 8% on an as-is basis;
- b) at least one evaporation system in direct or indirect fluid communication with the recovered solids stream, wherein the evaporation system is configured to directly or indirectly receive and expose the at least one recovered solids stream to at least one evaporation process to remove moisture from the 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) at least one dryer system configured to receive and dry the concentrated, recovered solids stream to form a dried product.
