TREATMENT METHOD OF VEGETABLE OIL Russian patent published in 2010 - IPC C11B3/00 

FIELD: food industry.

SUBSTANCE: method is implemented sequentially in four stages successively removing concomitant substances from the oil. At the first stage the vegetable oil is treated in vacuum to eliminate moisture and aromatic substances. At the second stage, the oil is machined to separate unhydratable substances and solid particles in the centrifugal force field. At the third stage water in added and the oil-water mixture is machined to separate hydrated substances as phosphatidic emulsion in the centrifugal force field. At the fourth stage the vegetable oil goes through a terminal treatment in vacuum to eliminate remains of moisture and aromatic substances. At the second and third stages vibration dispersion is used for machining that has a hydrodynamic effect by means of a vibrating radiator.

EFFECT: increased yield and reduced cost of the treated oil, simplified process of phosphatide withdrawal, decreased loss of the valuable product in the form of phospatide concentrate.
