Compose of impurities in the crude oil of Corn germ oil refining machinery:
Mechanical Impurities of Corn germ oil refining machinery:This impurities will not dissolve in the oil and fat .They are main silt, meal ,fiber ,grass and other solid impurities.
Fat soluble impurities of Corn germ oil refining machinery :free fatty acid , pigment , tocopherol,Hydro carbons ,Wax , Ketone , and trace metal etc
The process of Corn germ oil refining machinery:
1.Decolour tank is for bleaching grease.
2.Deodorizing tank is for desdorizing grease(stainless steel).
3.Conducting oil furnace provide thermal enery need for production, the temperature reach to 280degree.
4.Vacuum pump provides vacuum for bleaching, deodorization which can reach 755mmHg or more;
5.Air compreassor can dry the bleached clay
6.Air press is for filter clay
7.Steam generator can generate steam distillation required.
8.This kind of oil refining eqiupment make the oi reach the standard level national edible oil.
The oil grade after refinery of Corn germ oil refining machinery:
One grade oil of Corn germ oil refining machinery; after Degumming to Dewaxing No smell, Good taste
Two grade oil of Corn germ oil refining machinery; after Degumming to Deodorization No smell, Good taste
Three grade oil of Corn germ oil refining machinery; after Degumming ,Deacidification Four grade oil of Corn germ oil refining machinery; after Degumming, Has the inherent sunflower oil taste and smell, no odor.

Sunflower oil is the most widely used oil due to its high linoleic content which is considered nutritionally positive. The kernel accounts for 70% of the seed and the oil content is about 40%-45% in the seeds.
The whole sunflower oil making line contains three workshops:

Step 1.Degumming with water to remove the easily hydratable phospholipids and metals.
Step 2.Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.
Step 3.Neutralising of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.
Step 4.Bleaching with natural or acid-activated clay minerals to adsorb colouring components and to decompose hydroperoxides.
Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C).
