In a method for obtaining one or more protein preparations and oil fractions from sunflower seeds or rape seeds, at least three fractions are provided or formed from the seeds, of which a first fraction has a shell content of <1 mass percent, a second fraction has a shell content of <20 mass percent or <10 mass percent, the shell content being greater than the shell content of the first fraction but equal to at least >0.3 mass percent or >0.15 mass percent, and a third fraction has a shell content of >60 mass percent or >30 mass percent. Oil is separated from the first fraction by means of one or de-oiling steps to a residual oil content of <3 mass percent, whereby one or more oil fractions and an oil-free first fraction are obtained as protein preparations. The method makes it possible to convert all of the fractions which are accumulated during the preparation of the sunflower seeds or rape seeds, into ingredients of the highest possible quality for food, animal feed, energy or technical applications.

Methods and systems for producing improved hemp seed products, such as proteins and oils are provided.

The invention relates to a method for processing black liquor soap, particularly to a method for producing and recovering fatty acid esters and resin acids from black liquor soap. The method is based on a catalytic selective esterification of the soap.

The invention relates to a method for producing an oil rich fraction (OF) from primary feedstock (FS) that comprises water, first salt, second salt, and biomass. The feedstock (FS) is provided to a first reaction zone (Z1) of a conversion reactor (100), where it is allowed to react at a temperature of at least 350° C. in a pressure of at least 160 bar to form converted primary feedstock. The method comprises separating from the converted primary feedstock a first salt rich fraction (SF1), a second salt rich fraction (SF2), and an oil rich fraction (OF). The method comprises withdrawing the oil rich fraction (OF) from the first reaction zone (Z1) and withdrawing the first salt rich fraction (SF1) and the second salt rich fraction (SF2) from the conversion reactor (100). In the method the first salt rich fraction (SF1) comprises at least some of the first salt dissolved in the water, the second salt rich fraction (SF2) comprises at least some of the second salt in solid form, and at least one of the first salt and the second salt is a salt capable of catalysing the reaction of the biomass of the primary feedstock (FS) with the water of the primary feedstock (FS) to produce the oil rich fraction (OF). A device for the same.

Provided are methods to destabilize emulsion feedstocks. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours. The separation may occur at the moderate temperature.

Regenerative vapor energy recovery system and method for use with an ethanol plant. Regenerative vapors are partially condensed in a regenerative precondenser using a warm water stream. The warm water stream is fed to the regenerative precondenser and the partially condensed regenerative vapor stream is sent back to the ethanol plant where the stream is fully condensed using an existing condenser. The ethanol plant is thus operated at greater energy efficiency with lower operating costs than would be achieved with conventional systems.

The present disclosure is related to an apparatus and method for purification of biological feedstock, such as reducing or removing nitrogen containing compounds therein. The method can include subjecting the feedstock to a first separation step for obtaining a first fraction containing free fatty acids and nitrogen containing compounds, and collecting the residue containing acylglycerols. The first fraction is reacted with glycerol to obtain acylglycerols from the free fatty acid therein. This fraction is subjected to a second separation step for obtaining a second fraction containing nitrogen containing compounds, which is discharged as waste-product. The remains from the second separation contain formed acylglycerols and are collected.

The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using said compositions. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition.

The present invention provides a novel method for disposing of spent bleaching earth that is economically beneficial and avoids the problems typically associated with its disposal. By adding fine-particle lime (calcium carbonate) to the spent bleaching earth discharged from the process filters, spontaneous combustion can be eliminated. The material can then be transported in solid form to a production facility for use as a nutritious ingredient in making a wide range of feed products for poultry and livestock.

The present invention relates generally to corn dry-milling, and more specifically, to methods for producing a high protein corn meal from a whole stillage byproduct produced in a corn dry-milling process for making ethanol and a system therefore. In one embodiment, a method for producing a high protein corn meal from a whole stillage byproduct includes, in a corn dry-milling process for making ethanol, separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. The thin stillage portion is separated into a protein portion and a water soluble solids portion. Next, the protein portion is dewatered then dried to define a high protein corn meal that includes at least 40 wt % protein on a dry basis.
