PURPOSE: To provide a method and apparatus for separating and refining waste edible oil into edible vegetable oil and animal oil through an automatic or semiautomatic full line instead of manual refinement and separation operations to solve conventional problems such as disbursement of incidental expenses and quality deterioration of separated and refined edible oil. CONSTITUTION: The apparatus for separating and refining waste edible oil into edible vegetable oil and animal oil comprises a raw oil melting tank(1) in which collected waste edible oil(raw oil) is stored so that the raw oil is melted by indirect steam heat; a pump(2) for supplying the raw oil to the agitation tank by pumping the raw oil in the raw oil melting tank through a pipe(1a) connected to the raw oil melting tank; an agitation tank(4) for agitating the raw oil to evaporate moisture contained in the raw water and discharging foreign materials through a foreign material discharge pipe(4d) on which a valve(4e) is mounted; a pump(5) for supplying the raw oil into the natural cooling tank by pumping the foreign material and moisture removed raw oil in the agitation tank through a pipe(4c); a natural cooling tank(6) for constantly maintaining temperature of the oil to about 30 deg.C; a raw oil discharge pipe(6a) for discharging the raw oil in the natural cooling tank into the atmosphere and filter cloths at both sides of a raw oil refining frame of the filter press through raw oil distribution pipes; a cooling water inflow pipe(8) for supplying cooling water into a pipe fixed to the inside of cooling and heating frames of the filter press through cooling water distribution pipes, thereby cooling the filter cloths of the filter press so that animal oil is solidified on the filter cloths, and edible vegetable oil passes through the filter cloths to be dropped; a steam inflow pipe(20) for opening a valve(20a) connected to the cooling water inflow pipe, thereby supplying steam into the pipe to heat the filter cloths so that the solidified animal oil is melted to be discharged; a cooling water recovery pipe(9) for recovering cooling water passing through the pipe and supplying the recovered cooling water to discharge pipes to circulate cooling water to a cooling water generator; a steam recovery(30) for circulating steam discharged by opening a valve(30a) connected to the cooling water recovery pipe to a steam generator; an inclined path(40) for supplying the dropped edible vegetable oil to a storage tank(60); and a gathering tank(50) for gathering the animal oil dropped so that the animal oil flows to a storage tank(70).
