NOVELTY - Extracting (M1) corn oil from corn in ethanol production process involves obtaining a corn-based product from the ethanol production process; applying an alkyl acetate solvent to the corn-based product to extract oil so as to produce an extraction solution of at least corn-based product solids, oil, solvent and water; separating the extraction solution into a first phase containing solvent and oil and a second phase containing at least one of water and solids; separating the first phase from the second phase; and removing the solvent from the oil.    USE - For extracting corn oil from corn in ethanol production process (claimed) useful for producing food grade material and biodiesel.    ADVANTAGE - The corn oil generated using the method is suitable for use in biodiesel production, and can be sent to a refining facility for additional product handling or refining to sell the oil as a food grade material. The ethanol drying process eliminates conventional drying methodology and the heavy capital costs, energy costs and emission concerns associated with it. The absence of oil in the filter cake eliminates the plugging problems of traditional systems that prevents the use of reverse osmosis or micro-filtration membranes, and such downstream process also has same capability as the first approach of reducing the thermal requirement of the ethanol facility to 23060 Btu/denatured gallon of ethanol produced. The processes provide significant improvement in the productivity of ethanol production plant i.e. increase productivity by 20 wt.%. In the processes the product remaining in each process after the oil has been extracted consists primarily of cellulosic and proteinaceous components that can be sold as animal feed. This deoiled material and residue also has value as fuel and can be used to raise steam and/or generate power, including the production facility or other facilities. A food grade oil can be extracted using the methods, and the oil can then be sold for food applications or can be used as a feed stock for producing biodiesel. The deoiled milled corn and residues provide feedstock for the conventional dry corn milling ethanol plant where low energy filters are used in place of evaporators. The deoiled residues can also be gasified to product synthesis gas for ethanol, chemical and other power applications and they can also be pelletized for consumption as animal feed.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) producing co-products from an ethanol production facility prior to fermantation involving placing corn in a hammermill to produce a milled corn, transferring the milled corn into an extractor and blending the corn with an alkyl acetate solvent to form a combined mixture for extracting oil, separating the oil from the deoiled milled corn, removing the solvent from the oil and deoiled milled corn and recycling the solvent back to the extractor and transferring the deoiled milled corn to a fermentor to produce ethanol;    (2) producing co-products from ethanol production facility after fermantation involving obtaining thick stillage from ethanol fermentation unit, placing in a mixing unit with an alkyl acetate solvent mixture and blending to form a combined mixture for extracting oil, allowing the mixture to settle into first phase containing the solvent mixture and oil and second phase containing deoiled thick stillage and water, separating the first phase and distilling the first phase to separate the oil from the solvent mixture and recycle the solvent mixture to the mixing unit, placing the second phase in a reboiler desorption unit to remove unseparated solvent for recycling, filtering the second phase containing deoiled thick stillage to produce deoiled distillers wet grains and deoiled thin stillage, concentrating the deoiled thin stillage to produce a retentate syrup and drying the combined syrup and deoiled distillers wet grains to produce oil free distillers dry grains with solubles;    (3) producing co-products from ethanol production facility involving obtaining distillers wet grain from a post fermentation process flow system, blending the distillers wet grain with alkyl acetate solvent mixture to form combined mixture for extracting oil, allowing the combined mixture to settle into a first phase containing the solvent mixture and oil and second phase containing deoiled distillers wet grain and water, separating the first phase and distilling the first phase to separate oil from the solvent mixture and recycle the solvent mixture, placing the second phase into a reboiler desorption unit to remove unseparated solvent for recycling, removing additional water content from the second phase and placing the deoiled, dewatered second phase into combustion/boiler unit for the production of energy;    (4) producing co-products from ethanol production facility involving obtaining distillers dry grains with solubles from post fermentation process flow system, blending the distillers dry grains with solubles with alkyl acetate solvent mixture for extracting oil, separating the oil from the solvent mixture and recycling the solvent mixture, removing the solvent remaining in the deoiled dry grains with solubles to produce oil free distillers dry grains with solubles and recycling the solvent remaining;    (5) drying a wet solid co-product containing moisture from ethanol production process involving obtaining an ethanol stream from the production process, converting the ethanol into an azeotrope applying the ethanol azeotrope to the wet solid co-product to remove moisture and form an ethanol rich solid co-product, applying a stream of hot carbon dioxide gas from the ethanol production process to the ethanol rich solid co-product so as to remove ethanol from the solid co-product and form an ethanol-carbon dioxide stream, condensing the ethanol from the ethanol/carbon dioxide stream and recycling the carbon dioxide back into the production process, to leave a dried solid co-product;    (6) system for removing oil from corn products prior to fermentation in ethanol production facility comprising a hammermill for reducing whole corn to a milled corn; an extractor containing a solvent and in communication with the output stream from the hammermill; and a solvent stripper in operable communication with an output solvent mixture stream from the extractor; and    (7) a system for removing oil from a corn product post fermentation in an ethanol production facility comprising an extractor containing a solvent and in operable communication with a fermentor; a phase settler in operable communication with the extractor; a distillation assembly in operable communication with the phase settler; and a reboiler desorption unit operably attached to the phase settler.
