METHODS FOR ISOLATING OIL FROM PLANT MATERIAL AND FOR IMPROVING SEPARATION EFFICIENCY The present invention relates to method of isolating oil from plant material, comprising: a) generating cavitation bubbles within said plant material or a composition comprising said plant material, and b) collapsing said cavitation bubbles; wherein high velocity micro liquid streaming is produced within said plant material or composition comprising said plant material on collapse of said cavitation bubbles, and wherein said high velocity micro liquid streaming assists in isolation of oil from said plant material. The invention also relates to methods for enhancing coalescence of oil droplets or oil/water emulsion separation, comprising exposing said oil droplets or oil/water emulsion to low frequency wave energy. The present invention also relates to the recovery of emulsified triglycerides from any dilute oil-containing liquid using a series of steps including optional cavitation treatment, non-oil solids removal, oil concentration and coalescence. |
