Abstract: The present invention relates to a method and system of extracting an oil from an oil-containing raw material comprising the steps of providing a non-crushed oil-containing raw material, and treating the non-crushed oil-containing raw material. The treatment is performed by exposing the oil-containing raw material to vacuum, wherein the vacuum defines an absolute pressure of between 1 mm Hg and 150 mm Hg, and a temperature of between 0° C. and 45° C., and by subjecting the oil-containing raw material to crushing, simultaneously and/or subsequently to the step of exposing the oil-containing raw material to the vacuum, to provide a treated oil-containing raw material. By the method and system, high yield of oil with high quality can be obtained.

Abstract: Disclosed is a process for de-acidification of fats and oils, to obtain micronutrients, to obtain a fatty acid product, and recovery of refined oils, comprising: feeding pre-treated oil feed stream to a vacuum steam stripping section, stripping off volatile phases. Feeding the stripped off the volatile phases to a condensing stage providing a condensed phase and a vapour phase. Sending the condensed phase to a vacuum distillation operation and sending the vapour phase to a cold condensation stage. Subjecting the condensed phase to a vacuum distillation operation, and obtaining a high temperature distillate and a stream of volatiles.

Abstract: The present invention relates to a method for treating vegetable oils and/or animal fats comprising a vacuum steam stripping operation, condensing the neutral oils from vapour phase at an elevated temperature, retaining and sending back to the stripping column, allowing steam, volatile fatty acids, micronutrients together with other volatiles to pass to a cold condensation zone, and condensing the volatile fatty acids, micronutrients together with other volatiles in the cold condensation zone, producing a condensate and a stream of steam, non-condensable gases along with traces of fatty acids and other lighter hydrocarbons vapours. The invention may include a distillation step, either between the high and low temperature condensation zones or following the cold condensation zone.

Abstract: The invention relates to method for deacidification of fats and oils comprising: feeding stream (1) to a stripping section; condensing the volatile phase in a high temperature condensing zone, sending the condensed phase to distillation A; distillating the condensed phase, obtaining a volatile stream; passing the volatile stream along with the vapor phase from the condensation zone to a cold condensation zone obtaining a condensate and a stream (4); allowing stream (4) to continue to vacuum system and subjecting the cold condensate to distillation B; and producing a stream of fatty acids (5) and a stream of micronutrients (6).
