Zusammenfassung: | FIELD: food industry.SUBSTANCE: invention relates to fat-and-oil industry and may be used for vegetable oils purification. The method envisages hydration with an electrolytic solution, phosphatide emulsion separation from oil, neutralisation with water electrolysate with pH>7 with addition of salt to produce activated salt solution with concentration equal to 0.1-1% and neutralised oil separation. Then oil is hydrated by way of stirring with formation of centrifugal flows with vortices inside the flows; then one performs settling, drying and deaerating in vacuum under a pressure of 40-50 kPa. At first one performs oil pouring into the reactor and addition of water anolyte with pH7 с добавлением соли с получением активированного раствора соли с концентрацией 0,1-1% и отделение нейтрализованного масла. Затем масло подвергают гидратации путем перемешивания с образованием центробежных потоков с завихрениями внутри них, отстаивают, сушат и подвергают деаэрации в вакууме при давлении 40-50 кПа. Причем сначала масло заливают в реактор и добавляют анолит воды с рН |
