After bleaching the oil is practically pure, but still contains small quantities of original odoriferous matter.
The oil bleached by means physical bleaching is pumped in the Deodorization Plant. The oil is distilled at 240-270°C by means of steam and, under pressure and under vacuum for 30 - 60 minutes. Deodorization removes odorous substances, free fatty acids, and molecules generated from previous processes that give an unpleasant smell oil. During the Deodorization process, the peroxide value of oil is reduced down as minimum as possible.
The obtained oil (or oil blend) is odorless, tasteless, colorless and is ready for use in Soap Manufacturing to produce white soap.
After Refining, Bleaching and Deodorization, the crude oil is transformed in RDB oil (Refined Bleached and Deodorized Oil). In Soap Manufacturing this process is widely diffuse for Palm Oil and their by-product, like Palm Olein and Palm Stearine.
