摘要：
The invention provides a method and apparatus for reducing the energy neededtoprocess stillage in an ethanol refining operation. The method involves addingto stillage aneffective amount of at least one processing aid. The flocculant induces theseparation ofinsoluble material that would otherwise remain suspended in water but whichimpose a highshear energy cost on the refining processes. This allows for the removal ofinsoluble materialthat would otherwise be overlooked but which increase energy costs. Thisallows for moreefficient and effective separation and recovery of insoluble fractions of theconcentrated thinstillage that would otherwise be overlooked and lost in the process. Loss ofthese valuedfractions as a result of traditional processing techniques and those requiringextensive additionalenergy input results in the loss of high value co-products to low revenueprocess streams. Thisallows stillage to be processed more rapidly with a lower energy cost andimproved co-productrecovery economics.
