The role of winterization in sunflower oil refining plant

Sunflower oil winterization is also called sunflower oil dewaxing. The name winterization appears during winter. When the temperature is low, waxes present in sunflower oil will crystallize, which gives hazy appearance to the sunflower oil.

So sunflower oil dewaxing is essential when the sunflower oil is used as salad oil. The presence of wax makes the oil appear cloudy at room temperature. The oil normally becomes cloudy in 5–6h but with proper dewaxing the oil remains clear after 24h of storage at 0˚C.

Dewaxing machine in sunflower oil refining plant

The following steps are used in sunflower oil dewaxing plant:

1. Crude sunflower oil is refined in sunflower oil refinery plant.

2. The refined sunflower oil is heated to 55˚C, to make sure that all the sunflower oil is liquid.

3. The sunflower oil is cooled slowly to 7–8˚C.

4. Cooled sunflower oil is held in a specially insulated tank with a special slow-speed mechanical agitator. Preferably, the oil is held for 12–24h at this temperature.

5. At last, the filter machine is used to separate the dewax and sunflower oil.
