A method of extracting oil from oilseed comprising pressing seeds within a screw press including a screw auger rotatably mounted within a cylindrical expeller body, wherein the expeller body comprises a feed section, a compression section, and a discharge section, wherein at least one outlet is provided in the expeller body, preferably in or adjacent the feed section of the expeller, said method comprising the step of controlling the temperature of at least the compression section of the expeller by means such that the temperature of the material within the compression section does not exceed the glass transition temperature of the seeds.

This invention describes a method to extract and separate compounds from plant or animal material in a continuous process. The method uses dimethyl ether as a safe and efficient solvent which will extract polar and non-polar compounds. The extracted compounds are separated by distillation which is configured to provide individual compounds or groups of compounds.

An extractor to extract oil from a biological plant or portion thereof. A rigid container is provided, which has apertures at an upper extremity and a lower extremity. A collapsible bag is placed within the rigid container, the bag having an aperture at an upper extremity for accepting a biological plant and a solvent, and a second aperture at a lower extremity. A vacuum pump is operatively connected to the lower extremity of the collapsible bag within the rigid container. When a vacuum is applied to the bag within the rigid container, the bag collapses, squeezing the contents therein, so oil is extracted from the plant and the solvent is removed. The bag can be removable or the entire rigid container unit and its contents can be lifted out of the apparatus. The low-weight, squeeze dried residue in the collapsed bag facilitates material transfers and later disposal. This design also allows the rigid container to be less sturdy, as it does not take the force of the vacuum, reducing cost in construction of the rigid container assembly or assemblies.

The present disclosure includes a method for processing a beer stream for the recovery of oil. The method include a step of extracting oil from a beer stream into an organic phase comprising an organic solvent to provide in the organic phase at least a portion of the oil. In general, a beer stream refers to a composition containing alcohol, water, oil, and particulates, and can be a result of a fermentation process. When the beer stream is a beer stream from a fermentation process, it can be referred to as a fermentation broth even if it is no longer being subjected to fermentation. The beer stream can contain other components commonly found in a stream coming off a fermentation process such as, for example, glycerol and acetic acid. A method for producing ethanol, and an ethanol production facility are provided.

The invention is directed to a process for the extraction of one or more oil-soluble components from plant material, to an oil comprising one or more oil-soluble components from plant material, preferably obtainable by the process of the invention, a physiologically acceptable product comprising the oil, and to the use of plant material. The process of the invention comprises: a) providing oil and plant material; b) heating the oil to a temperature of 10-80? C., preferably 50-80? C.; c) contacting the oil with the plant material while the oil and plant material are in motion relative to each other, thereby extracting one or more oil-soluble components from said plant material; d) replacing plant material with new plant material during the extraction process; and e) collecting said oil when the concentration of the one or more oil-soluble components has reached a desired level.

The invention relates to a continuous process for fractionating a suspension chosen from a microalgal biomass or milk.

A method of recovering an extraction aid from distillers corn oil, by directing stillage containing distillers oil and an extraction aid to a centrifugal separator, recovering a light phase from the centrifugal separator, the light phase containing at least a portion of the distillers oil and at least a portion of the extraction aid, cooling the light phase and causing a precipitate to form, and recovering a precipitate from the cooled light phase containing at least a portion of the extraction aid. A method of recovering distillers oil.

The invention relates to a continuous process for fractionating a suspension chosen from a microalgal biomass or milk.

The present invention relates to isolated polypeptides having lysozyme activity and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

A system and method for extraction of cannabis oil from cannabis plant materials by further reducing the temperature of the extraction system effluent, which may be a mixture of solvent, the desired cannabinoids, and/or the undesired non-polar extracted waste from the plant material. This invention improves the extraction process by: 1) enhancing the rapid filtering of the waste material from the process stream, speeding up the overall process, and 2) improving the quality of the product, yielding a purer extract as evidenced, in part, by its lighter (yellow/gold) color as compared to less-pure green/brown extracts.
