METHOD FOR PRODUCTION OF VEGETABLE OIL OF OIL-CONTAINING SEEDS Russian patent published in 2015 - IPC C11B1/00 

FIELD: food industry.

SUBSTANCE: method for production of vegetable oil from oil-containing material includes seeds separation from impurities, conditioning, seeds hulling with the help of hulling machine tools, treatment in fanning installations with the help of hulls isolation from kernels with subsequent removal, kernels milling with the help of rolling machine tools to produce mashed mass. The produced mashed mass is mixed in continuous mixers with a sufficient quantity of recycle vegetable oil and is supplied, with the help of dosers, into a vortex layer apparatus (VLA) for treatment in rotating electromagnetic field until production of a suspension consisting of vegetable oil and disintegrated residues of seed kernels. The layer suspension produced after treatment in VLA and heated in the above apparatus to 60-85°C is supplied by a forcing pump into the filter press where it is separated, filtered through porous napkins, to produce agglomerated cake (expression cake) and filtrate (vegetable oil).

EFFECT: invention enables production of oil that preserves its basic useful properties, having been produced at lower temperatures as compared to traditional manufacture methods, reduction of energy intensity and of operational costs as compared to traditional vegetable oil manufacture technologies.
