Physical Refining & Deodorization

Process Description

Deodorization is a stripping process in which a given amount of a stripping agent (usually steam) is passed for a given period through hot oil at a low pressure. Hence, it is mainly a physical process in which various volatile components are removed.

Timing is of essence in the Deodorization Plant Process wherein too much takes away from the inherent Flavors of the oil that are essential. On the other hand, if the deodorization process is too short, some precursors may remain the in the oil resulting in development of unwanted flavours during storage.

Deodorization is aimed at guaranteeing good oil quality while preserving nutritional value and eliminating contaminants and unwanted flavouring agents…
The Physical Refining process is possibly the most important step in edible oil refining and is aimed at creating a fatty acid free, odourless product with a very light hue and very stable against oxidization.

The simplest and most economical way to execute physical refining is to pass the oil through a serious of compartments intermittently placed horizontally and vertically while subjecting it to steam stripping under high vacuum. This ensures all volatiles like fatty acids, aldehydes, ketones, alcohols, and colouring agents are removed.

The Physical Refining Plant process is monitored continuously through instrumentation with precise control over all variables like temperature, flow rate, vacuum, and time.
