VEGETABLE OIL REFINING LINE Russian patent published in 2002 - IPC

FIELD: fat and oil industry; production of refined oils. SUBSTANCE: vegetable oil refining line includes unit for mixing oil with alkali reagent, unit for separating phases into neutralized oil and soap stock, unit for mixing neutralized oil with water, unit for separating neutralized washed oil and flushing water and unit for drying neutralized washed oil. Line is additionally provided with exposure unit mounted after unit mixing oil with alkali reagent. Exposure unit is made in form of cylindrical housing with spherical cover and bottom; ratio of diameter of cylindrical housing to its height ranges from 1: 2 to 1: 4; its volume is equal to 1.0 to 2.0 cu. m. Unit used for separating phases into neutralized oil and soap stock and unit used separating phase into neutralized washed oil and furnishing water are made in form of settlers; each settler includes inlet and outlet collectors and separating plates located at distance of 20 to 40 mm in parallel relative to each other; they are mounted at angle of 40 to 60 deg. relative to level. Line is additionally provided with unit for preparation of neutralized washed oil for drying. This unit is made in form of solenoid consisting of cylindrical housing with permanent magnetic field excitation windings and core mounted inside housing. Relative position of housing and core ensure availability of circular clearance crossed by lines of magnetic flux. EFFECT: improved quality of refined oil; increased yield; reduced consumption of flushing water. 3 dwg, 1 tbl
