A method for obtaining a protein ingredient for animal feed from seeds of sunflowers or rape includes shelling the sunflower seeds or rapeseeds up to a shell content of <2.5 wt %, mechanically partially extracting the oil from the shelled sunflower seeds or rapeseeds by pressing, up to a fat or oil content in the region of >6 and <25 wt %, and carrying out at least one extraction step for further extraction of the oil with at least one organic solvent or supercritical CO2, up to an oil content of less than 3.5 wt %; and subsequently desolventing, wherein at least one protein-denaturing treatment of the sunflower seeds or rapeseeds is carried out between the shelling of the sunflower seeds or rapeseeds and the obtaining of the protein ingredient. Due to its good digestibility, the protein ingredient can be used as an at least partial replacement for animal proteins in animal feeds.

An oil production apparatus includes a reaction vessel where raw material composed of an agricultural residue or a fishery residue is fed, a water vapor injecting unit for injecting saturated water vapor into the reaction vessel, a kneading unit for kneading a content in the reaction vessel, a temperature sensor disposed at a lower part of the reaction vessel, a pressure regulating unit regulating the pressure, a control unit for controlling driving of the water vapor injection unit, the kneading unit, the pressure regulating unit, a housing for making a working area for extraction of oil oxygen-free, a solid-liquid separation unit for separating solid from a product and water removal unit both disposed in the housing, and a nitrogen injection unit for injecting nitrogen into the housing.

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.

A process for producing a plant protein ingredient and the plant protein ingredient is disclosed. The process may include comminuting the plant material into particles, thereby obtaining comminuted plant material; separating the particles of the comminuted plant material into a finer fraction and a coarser fraction; washing the finer fraction with an aqueous alcohol solution for reducing the solubility of proteins contained in the finer fraction, thereby obtaining a washed finer fraction; enzymatically treating the washed finer fraction to remove at least a part of the phytate and/or cell wall components to obtain an enzymatically treated finer fraction, and optionally removing at least a part of water soluble components from the enzymatically treated finer fraction, thereby obtaining the plant protein ingredient; and drying the plant protein ingredient to a moisture content of at most 45% (w/w).

A cannabis oil extraction method includes performing grinding assisted extraction in the presence of solvent, co-solvent extraction with subcritical CO.sub.2 comprising, degassing the CO.sub.2 and separating the mixture by centrifugation.

The present invention relates to a polyunsaturated fatty acid composition comprising Omega-3 fatty acids, 17-HDHA and 18-HEPE. The composition can furthermore comprise DPA and/or an acceptable carrier and can be present in a capsule or other suitable dosage unit. The invention also relates to the process of obtaining the composition and methods for using same.

Exemplary embodiments are directed to a diffuser assembly configured to be disposed in an extraction path of an extracting solvent in an extraction vessel. The diffuser assembly includes a housing configured to be disposed within the extraction vessel, the housing including an inner surface and an outer surface. The diffuser assembly includes an inlet structure disposed within the housing. The diffuser assembly includes an outlet structure disposed within the housing and spaced from the inlet structure to form a mixing chamber between the inlet structure and the outlet structure. The inlet structure and the outlet structure each have a porosity configured for passage of the extracting solvent therethrough. Passage of the extracting solvent through the inlet structure, the mixing chamber, and the outlet structure redistributes flow of the extracting solvent along the extraction path.

A dual phase re-circulating extraction apparatus comprises at least one extraction vessel, at least one separation chamber, and a circulation conduit configured to direct a process fluid into the extraction vessel, where it may come into contact with a source material to form a mixture, and is then passed to the separation chamber, where the process fluid separates from the extracted material, and the process fluid is recirculated back to the extraction vessel. The apparatus includes a gas pump, at least one heat exchanger, and a liquid pump, each connected to the conduit, to efficiently convert a relatively low pressure gas after separation to a relatively high pressure liquid or supercritical fluid for extraction. The apparatus can be configured to enable a batch mode process allowing continuous flow to the separators while the extractors are cycled online and offline in a sequence to enable servicing and reloading.
