Summary This paper has discussed the early methods of the refining of vegetable oil and present‐day continuous refining equipment. The purpose was to report on the advantages of the centrifugal contactor for water washing of vegetable oil. There are important advantages to be obtained by the use of Podbielniak Rotating Contactor for water washing of alkali‐refined oils. One‐to‐ten tank car capacity with one centrifugal contactor results in space and installation savings. Stainless steel construction permits use of acid treats. Pressure operation prevents oxidation of hot oil and emulsions formed by mixing with air. Installation can be made fully automatic. Periodic cleaning is not required. Countercurrent flow produces higher quality refined oil with 50% lower neutral oil loss in wash water.
