Improved oil quality!


The basic principle is as simple as effective:

In the first stage, or pre-bleaching, unbleached oil is blended with once- used bleaching earth.  In consequence there is a 75% initial reduction of the undesirable accompanying substances. In the second stage, or main bleaching, pre-bleached oil is blended with fresh bleaching earth.
