METHOD FOR PROCESSING FATS AND OILS Russian patent published in 2017 - IPC C11B3/00 

FIELD: food industry.

SUBSTANCE: method for neutralizing the acidity of fats and oils to produce micronutrients and a product of fatty acids and to extract refined oils includes: feeding the pretreated oil stream to a vacuum vapour distillation section distilling volatile phases; feeding the distilled volatile phases to the high-temperature condensation stage or to the combination of the high-temperature and the mid-temperature condensation stages to obtain the condensed phase (A) and the vapour phase (E); sending the condensed phase (A) to the vacuum distillation process and sending the vapour phase (E) to the low-temperature condensation stage; the effect on the condensed phase (A) of the vacuum distillation process and obtaining a high-temperature distillate and a stream of volatile substances; feeding the vapour phase (E) from the high-temperature condensation stage together with the stream of the volatile substances (C) from the vacuum distillation process to the low-temperature condensation stage to obtain the stream of non-condensable gases and low-temperature distillate, providing the stream of the non-condensable gases the possibility to be retained in the vacuum system, and extracting he refined oil stream from the vacuum and vapour distillation section.

EFFECT: invention makes it possible to increase the content of tocopherols during the neutralisation of oils.
