METHOD FOR INTEGRATED PURIFICATION OF VEGETABLE OILS Russian patent published in 2015 - IPC C11B3/00 

FIELD: food industry.

SUBSTANCE: method for integrated purification of vegetable oils envisages cold hydration of oil with further vacuum membrane filtration with usage of hollow-fibre membranes made of a polymer material having pore diameter within the range of 0.01 - 5 mcm while the membrane fibre has an inner diameter within the range of 0.1 - 10 mm; the inner space of the membrane hollow fibres is connected to a vacuum system for creation of a pressure gradient on different sides with a membrane semi-permeable partition and for generation of a 0.1 - 0.9 kgs/cm² vacuum inside the fibres to enable the possibility of ensuring a directed flow of oil being purified across the whole membrane surface; the polymer material is selected from the group including polyvinylidenfluoride, PVC, polypropylene, polyethylene, polyethersulphone, polyacrylamide, cellulose acetate or their combinations or their copolymers.

EFFECT: invention allows to create a cost-efficient and hi-tech method for integrated purification of vegetable oils that enables production of a higher quality product with expenses on clearing vegetable oils from phosphatides, cereous substances, high-melting glycerides and other impurities reduced as compared to the available oil purification technologies, with the minimum quantity of wastes and low-value products generated.
