Sunflower oil is different with other vegetable oil, containing too much wax. Normally crude sunflower oil contains about 0.06-0.1% wax, The exist of wax will make bad effect on oil taste and transparency,especially when cooking, this oil will have smoke and strong smell, so wax must be removed after sunflower oil refining. Sunflower oil refining plant includes sunflower oil refining machine and sunflower oil dewaxing machine.

Sunflower oil dewaxing process:

Crude sunflower oil⇒heating ⇒ heat exchanging⇒ Cooling ⇒crystallizing ⇒maturating⇒ filtering ⇒ heat exchanging ⇒ final edible oil 

 



 Main sunflower oil dewaxing machine:
1. Cooling system
2. Heat exchanger 
3. Cystallizers
4. Maturators
5. Filters

Features of dewaxing machine

1.Before dewaxing, crude sunflower oil is stored inside oil tank, oil temperature is always lower than wax, then part of wax is already sepatated which is not good for crystallization. In order to make good result of crystallizing, Then crude oil need to be heated and make wax dissolved completely inside crude oil.
2. Cystallizing should be  at a certain speed to make oil cooling even ,mixing if necessary, this process can not be too fast
3. After cystallized at a certain temperature, oil is cooled down , mixing is stopped, rest long time for maturating to make wax pacels grow big. Maturating period is about 12-16h.
4. After maturating, oil will be filtered by vibrating filter. Better to use two filters alternately to keep continuous working.

After dewaxing, we will get edible sunflower oil by this complete sunflower oil refining plant  ,meeting national standard.
