CONTINUOUS BLEACHER

Bleaching Process is the third step in vegetable oil refining which commences after complete of effective neutralization process.

Ferro provides a SS-316 and SS-304 (as per customer requirement) pressure vessel named FX-Bleacher which is used to carry out the Bleaching Process. A Bleacher is carefully designed equipment based on design parameters to ensure perfect bleach-ability of the neutralized oil. The process has its own importance.

The purpose of Bleaching is to remove the color pigments contained inside Vegetable Oils. The neutralized oil is heated at additional temperature through low pressure steam within the coil inside the vessel. The oil is then treated with Bleaching Clays that absorb the color pigments. The addition of amount for bleaching clay varies from oil to oil. It also depends on the color content of the crude oil and the desired quality oil colour index. This bleached oil is then passed through the Pressure leaf filters to filter out the used Bleaching clay.
