soybean oil extraction plant full production line with refinery .

Soybean oil extraction plant is used to process seeds to high quality cooking oil. But about extracting crude oil , we have two methods to process seeds to oil, one is mechanical press method , the other is solvent extraction method.

soybean oil extraction plant with pretreatment line.

Basic information about whole line for soybean oil extraction plant:

1.Pretreatment and prepress.

Brief processes:

Raw material--Magnitic seperating--Metal impurities--Cleaning--Other impurities--Husking--Sunflower seed hull--Cooking--Prepressing--Crude oil--Sunflower seed cake--Extracting Workshop

Functions of main parts:

Magnitic seperating:In order to remove the metal impurities, so that can prevent damaging the equipment and occuring safety accidents.

Cleaning: To remove the imourities in the raw matrial such as soil, stem and leaf, hull and moldy seeds.

Husking: In order to improve the oil yielding rate and the quality of crude oil and meal, reduce the wear to the equipment, the hull must be removed.

Cooking: This processing can improve prepressing oil yielding rate and the quality of the cake, adjust the moisture, temperature and plasticity of the flake.

Prepressing:To squeeze out part of the oil in the raw material, and improve extracting effect.

2.Solvent Extracting:

Brief processes:

Fresh Solvent--Cake--Extracting--Wet Meal--Desolventising--Meal--Miscella--Evaporating and stripping--Solvent mixture--Condensing and Recovering--Crude Oil--Solvent Recycling--Refining Workshop.

Functions of main parts:

Extracting:To extract the oil in the cake by solvent, the general solvent is 6# extraction solvent oil or commercial hexane.

Desolventising:To remove and recover the solvent in the meal; Dry and cool down the meal at the same time.

Evaporating and stripping:Heating the the miscella by indirect steam, so that can vaporize the solvent and concentrate the miscella.

Solvent recycling: This process is to recover the solvent, decrease solvent comsuption, keep safety prodution and improve product quality.

3.Soybean oil refining machine.

Brief processes:

Crude Oil--Hot water--Degumming--Oil Foot--Alkali liquor--Deacidfying--Soap Stock--

Activeted Clay--Decoloring --Waste Clay--Deodorizing--Dewaxing--Wax--Refined Oil

Functions of main parts:

Degumming:To remove the colloid soluble impurities, and prepare for the subsequent refining process.

Deacidfying:To remove the free fatty acid in the crude oil.

Decoloring: To remove the pigment in the crude oil by adding active clay, so that can improve the oil quality.

Deodorizing:To remove the odor in the oil, so that can improve the flavor, stability, color and quality of the oil.

Dewaxing: To renmove the wax in the oil and improve the quality of the oil.
