FIELD: fat-and-oil industry. SUBSTANCE: oil or fat is mixed with water and chemical (flocculant) and neutralizing agents to form reaction mixture. The latter is agitated by creating and bringing into interaction two counter-current flows of reaction mixture followed by separation of interaction products. Apparatus has at least two reaction vessels, pipelines, and shutoff valve accessories. Each reaction vessel contains two connection pipes disposed on one side of vessel and connected to the first pipeline. Ends of connection pipes are located inside reaction vessel at the opposite sides of the latter. Third connection pipe is connected to the second pipeline of each reaction vessel and located on opposite side of reaction vessel being directed toward the first two connection pipes. Reaction vessels communicate with vacuum line. EFFECT: achieved production of high-quality product with fixed peroxide index, simplified technology, and reduced power and materials consumption. 8 cl, 1 dwg, 1 tbl, 12 ex
