Corn germ oil extraction process

The process flow of the pretreatment section of the corn germ oil production line:

Process flow: corn germ → magnetic separation → cleaning → steaming and frying → pre-pressing → sent to the leaching workshop. The pretreatment section in the corn germ oil production line is more important because it directly affects the oil extraction effect.

Process characteristics: 1. Create a good production environment. 2. Minimize oil loss, accelerate oil yield, and improve the quality of oil and meal. 3. Special utilization of the separated impurities.

The process flow of the extraction section in the corn germ oil production line:

Solvent steam ↓ ↓ leaching → mixed oil → secondary evaporation → gas stripping → crude oil:

Type of extractor: rotating extractor, annular extractor, chain extractor

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

Advantages of the leaching process: 1. High oil rate and less residual oil in the meal. 2. Low labor. 3. Good working environment. 4. Good meal quality. 5. Negative pressure leaching speeds up the quality of crude oil.
Process features: 1. Negative pressure evaporation can ensure better oil quality. 2. The leaching system can be applied to various oil materials. 3. The entire equipment is equipped with an exhaust gas recovery system. 4. It saves total energy and maximizes the recycling of heat energy to save steam.

Refining section of corn germ oil production line

Process flow: corn germ oil crude oil → degumming and dephospholipid → deacidification → drying → decolorization → deodorization → degreasing → dewaxing → finished product corn germ oil refining principle: refining is based on different uses and needs, comprehensive utilization of physics and chemistry Method to remove harmful impurities and useless impurities to obtain high-quality finished oil.

Advantages of the refining process: 1. The impurity content after refining needs to be less than 0.2% 2. The circulation system saves energy and money 3. Low fuel consumption.
