METHOD FOR SEPARATING OF FILTRATION SEDIMENT OF "FROZEN" SUNFLOWER OIL PRODUCTION INTO OIL, WAX CONCENTRATE AND FILTER-POWDER Russian patent published in 2003 - IPC

FIELD: fat-and-oil industry, in particular, sunflower oil production and refinement. SUBSTANCE: method involves mixing filtration sediment at temperature of 95-100 C with 0.4-0.3%-aqueous soap solution; settling resultant mass and separating into wet filter-powder, aqueous soap solution and oil-wax mixture; separating oil from oil-wax mixture by filtering through fabric cloths in the presence of filtration sediment or regenerated filter-powder; expelling oil from resultant sediment by means of mechanical oil expeller; mixing remains from fabric cloth with 0.4-0.3% aqueous soap solution; settling resultant mass and separating into wet filter-powder, aqueous soap solution, and wax concentrate. EFFECT: reduced cost, provision for ecologically clean fire and explosion safe method for separating of filtration sediment into valuable products. 3 cl, 1 dwg, 5 ex
