Small to Large Scale Edible Oil Solvent Extraction Plant | Cooking Oil Making Process

The extraction of oil mainly involves three steps: pretreatment , extraction , and refining . The extraction process, known for its high efficiency, high oil yield, and high degree of mechanization, is widely adopted by many large oil processing enterprises. oil solvent extraction equipment can effectively reduce the residual oil content in the extraction cake to less than 1%, making efficient use of high-quality resources and improving production efficiency for oil plants.

The principle of oil solvent extraction equipment is to fully soak and contact the solvent with the oil material in the extractor, extracting the oil to obtain miscella. The miscella is then separated from the oil to obtain crude oil.

A complete set of extraction equipment mainly consists of four parts:

1.  Solvent extraction system:

oil extraction equipment;

2. Wet meal desolventizing system:

desolventizing of extraction meal;

3. Miscella evaporation system:

separation of mixed oil and oil through evaporation;

4. Solvent recovery system:

recovery and reuse of evaporated solvent through condensation.

Extraction oil is obtained by using a chemical process where oilseed is pressed into thin flakes and soaked in light gasoline to obtain miscella . The miscella is then heated and distilled to remove the light gasoline, resulting in semi-finished oil, which is further processed to obtain edible oil.

Compared to the pressing oil process, extraction oil often uses production line operations with a high degree of mechanization of oil equipment, resulting in lower production costs. Extraction production lines are usually the choice for large edible oil processing plants, requiring significant investment, high output, and a large number of equipment models and quantities. For a complete set of extraction equipment production lines, Huatai is a good choice.
