Cooking Oil Refinery Plant

This is the first step in refining and is also known as the Pretreatment Process. In the degumming process, the gums are precipitated and separated by the centrifugal separation technique. If the gum content in the oil is low, only gum-conditioning is required to be done and there is no need to go for separate degumming process. The degumming can be carried out in the same neutralization vessel.

Every cooking oil consists certain amounts of free-fatty acids FFA's that increase the rancidity in oil and is harmful for human consumption. In neutralization, the FFA's are removed by reacting them with caustic soda- NaOH in the neutralizer at a certain temperature and performing the stirring. In this way, FFA gets separated in the form of soap stock. Tinytech offers neutralization units.

The color pigments in the oil are removed in the bleaching process. The neutralized oil is treated with certain chemicals like activated earth which removes the color from the cooking oil. This process is also carried out under temperature. The bleached oil is then filtered so that the added chemicals and particles are separated from the oil.

The deodorization is an important process in the cooking oil refining. This process is used to remove the odor from the oil. Every oil contains certain typical natural color. During the previous processes, certain unwanted odor is applied on the oils. The deodorization process removes this odiferous material. It is carried out under high temperature and vacuum systems. At the completion of the process, we get the deodorized-odorless cooking oil.
For sunflower oil and corn oil, separate dewaxing process is carried out and for palm oil; separate fractionation process is carried out.
