This process is applied specially to sunflower oil with lower wax content. The bleached oil is cooled through oil-to-oil heat exchanger and then pumped into crystallizers where small amount of the filter aid like CELITE is dosed. The oil is continuiously kept at low temperature, which aids crystallization of waxes.

The crystallized oil is then fed to a maturator for further improvement of the wax crystals. The oil is the pumped into a pressure leaf filter where the filter aid retains the wax and clear dewaxed oil is produced.
