NOVELTY - Processing a fermentation product of a fermentation process in a biorefinery that performs distillation of ethanol, where the fermentation product comprises a liquid component and a solids component, involves: (A) depositing at least the solids component on an apparatus comprising a belt; (B) as the solids component is along the apparatus, applying a solvent to the solids component; and drying the solids component.    USE - For processing fermentation product of fermentation process in biorefinery that performs distillation of ethanol, where fermentation product comprises liquid and solids component (claimed). The ethanol produced is useful for blending with gasoline for use in motor vehicles.    ADVANTAGE - The system is useful for the production of ethanol and co-products, form fermentation product in biorefinery that performs distillation of ethanol, where fermentation product comprises liquid component and solids component. The system facilitates overall reduction in the use of energy by reducing mass of wet solids supplied to a distillation system; reduces amount of energy used to dry the wet solids component of fermentation product by increasing ethanol concentration of wet solids; and facilitates recovery of co-products including bioproducts and other biochemicals extracted from components of fermentation product. In the process before drying, the wet solids components, produced from the fermentation product in the biorefinery, are washed with solvent such as ethanol to increase ethanol concentration, which facilitates reduction of energy required for drying. Washing with ethanol leads to lower drying energy consumption regardless of whether liquid component and solids component (e.g. wet solids) have been separated by separation process. The ethanol wash may also be used with wet solids exiting distillation process, as in existing plants. Increasing the ethanol concentration of wet solids components decreases the amount of energy required to dry wet solids components at least partially because water has a relatively high boiling point, heat capacity, and enthalpy (heat) of vaporization as compared to ethanol; where relatively high amount of energy is required to heat water to a temperature sufficient to vaporize the water, and a relatively low amount of energy is required to heat ethanol to a temperature sufficient to vaporize ethanol. The dried solids component of fermentation product obtained can be constituted into a meal that may be used for animal feed.
