Deodorizer

Effective deodorization is a complex vacuum steam distillation process that involves using high-pressure steam to heat the oil to a precise temperature for stripping impurities and then cooling it to retain the natural oil characteristics.

Deodorization is a steam stripping process wherein a good-quality steam, generated from de-aerated and properly treated feed water, is injected into soybean oil under low absolute pressure and sufficiently high temperature to vaporize the Free Fatty Acid (FFA) and odoriferous compounds and carry these volatiles away from the feedstock. Oil losses during deodorization can be classified into two categories: chemical and mechanical. Chemical losses consist of the removal of the undesirable components: FFA, aldehydes, ketones, peroxides, polymers, and other volatiles.  …
