Edible Oil Refining Process

Corn germ oil machine/plant

Corn germ oil factory constructed for our customers

Corn germ oil has many benefits to human body; it is good for heart health, and it is rich of vitamin and linoleic acid.

Corn germ from the corns    

 Here, we would like to introduce you our corn germ oil production line briefly.
Corn germ oil production line contains three workshops:

1.Pretreatment workshop
2 Extraction workshop
3.Crude oil refining workshop


ⅠPretreatment section of the corn germ oil production line
Craft flow of corn germ oil production line:
Corn seeds→ Magnetic separating→ cleaning → cooking → prepressing → to extraction workshop
Pretreatment section of the Corn germ oil production line is very important because it affecting extraction effect directly.
Craft features of corn germ production line :
1. Create good production environment.
2. Minimize the total fat loss, increase oil yield rate and improve the quality of oil, cake and meal.
3. Comprehensively utilize impurities and offal.

Ⅱ Extracting section of the corn germ oil production line
Craft flow:


Solvent                               steam  
  ↓                                      ↓                                                                                  
Extraction → mixed oil → evaporation→ steam-stripping → crude oil

Extractor types:
Level rotation extractor, loop type extractor, chain extractor

Extraction methods:
Use organic solvent through soaking or spraying contact method to extract oil from corn germ.

Advantages of extraction craft:
1. High oil yield rate, low residual oil in meal;
2. Low labor intensity;
3. Good working environment;
4. Good meal quality.
5. Negative pressure evaporation helps to improve crude oil quality.

Craft features:
1. Adopting negative pressure evaporation can ensure excellent oil quality;
2. Extraction system is highly adaptable, and can adapt to different raw material;
3. All equipments are provided with exhaust gas absorption systems with excellent absorption effect;
4. Full energy-saving design utilizes heat energy for many times and saves steam consumption;

Ⅲ Refining section of the Corn germ oil production line

Craft flow of corn germ oil production line:
Crude corn germ oil→ degumming and dephosphorization→ deacidification→ drying→ decolorization→ deodorization→ defatting→ dewaxing→ finished corn germ oil.
Refining methods:
Oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.

Advantages of refining craft:
1. The impurity of oil must be less than 0.2% after refining;
2. Recycling system save power and money;
3. Lower oil waste.

Craft features:
1. Continuous alkali refining shortens contact time between oil and lye, reduces grease saponification, lowers refining consumption, and improves refining efficiency.
2. Decolorization adopts technology of combining premixing and steam mixing bleaching, which improves bleaching efficiency, saves consumption of bleaching clay, and it's simple and convenient to operate; and negative pressure state avoids oxygen in the air from contacting with hot oil, thereby ensuring oil product quality, inhibiting acid value to rise again, and lowering peroxide value.
3.Deodorization adopts new type continuous deodorization equipment which is applicable for deacidification and deodorization of plant oil with high acid value and low resin content, the actual production proves its most obvious advantages are strong deacidification ability, excellent hot bleaching effect, high refining rate, good oil quality and so on.
4. The process has multiple heat exchange, which makes full use of the heat energy system, effectively reduces steam consumption.
