A method for increasing oil yield from a whole stillage byproduct produced in a corn dry-milling process for making alcohol (e.g., ethanol) and/or other biofuels/biochemicals and a system therefor is disclosed. In one embodiment, the method includes separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. Thereafter, the thin stillage portion can be separated into a water-soluble solids portion, which includes oil, and a protein portion. Oil can be recovered from the water-soluble solids portion. In one example, to break oil in water emulsions in the water-soluble solids portion and increase the oil yield, a treated portion of the recovered oil, which may be heated, may be re-introduced/recycled to the water-soluble solids portion prior to the oil recovery.

Provided herein are systems and methods for the facile extraction and purification of oils from plant material, including cannabis and hemp. The systems and methods herein are versatile, and may utilize a wide range of solvents to extract oils from a variety of plant-based material. Further, the provided systems and methods are closed loop, reducing the loss solvent and decreasing the risk of safety concerns such as human exposure to solvent chemicals or explosion of volatiles. In some embodiments, the systems and methods remove impurities from the extracted oils, for example waxes or other precipitates, and provide a higher purity and higher quality extract.

The invention relates to an apparatus for the treatment of spent material said treatment including the desolventisation and toasting of said spent material (DT) to yield desolventized spent material and/or the drying and cooling of said desolventized spent material (DC) to yield meal and/or their combination (DTDC), said apparatus being made of stacked trays supporting said spend material said apparatus being equipped with means to provide at least one fluid phase going through said spent material, wherein at least a portion of the said at least one fluid phase is pulsed through said spent material.

The present disclosure relates to methods, systems, and devices for efficiently extracting high quality oils and distillates, such as essential oils and hydrosols, from organic matter, such as plant matters. In some embodiments, organic matter comprises active chemical elements, which are used for therapeutic, medicinal, culinary, and industrial purposes.

The disclosed embodiments include systems and methods for the solvent extraction of a substance from a material. The disclosed systems include multiple tanks and an extraction chamber in communication with the tanks. Solvent transport is accomplished by heating and/or cooling selected tanks to cause the solvent to be transported between tanks.

Methods of and devices for recovering oil and protein and increasing production yields using two centrifuges in series or a centrifuge with dual oil and protein separating functions in a dry mill are provided.

Compositions for increasing corn oil recovery and embodiments of methods for using the composition for corn oil separation are described. The composition(s) incorporate an admixture that includes a polymer selected from a polyglycol ester, a polyethyleneoxide-polypropyleneoxide block copolymer, a poloxamine, or a mixture thereof. The methods include admixing the compositions with a process stream for, for example, the extraction of oil from milled corn and residues from a fermentation step, including stillage (e.g., thin stillage or mid stillage), distiller's wet grain, distiller's dry grain and distiller's dry grains with solubles.

Systems and methods are provided for improving co-product recovery, such as oil recovery, from grains and/or gain components used for biochemical and/or biofuel production, such as alcohol (e.g., ethanol) production, using surfactants, flocculants, and/or other emulsion-disrupting agents. At one or more points prior to or during emulsion formation, as well as after emulsion formation, surfactants and/or flocculants are added to the biochemical and/or biofuel production process to prevent emulsions or break those already formed to improve co-product recovery, such as oil recovery.
