Palm oil physical refining process(2)
Palm oil physical refining process can be divided into 3 parts: pretreatment process, steam refining and deodorization process, and fractionation.
Palm oil physical refining process
Steam refining and deodorization process of palm oil physical refining process:
In this process, the pretreated oil is purified by three operations conducted under high vacuum at high temperature. First, the fatty acides are removed by multistage countercurrent contact with steam. Then, the pigments are converted to colorless form by retention of the hot oil for the required reaction time. Finally the oil is deodorized by additional multistage countercurrent contact with steam.
