Henan Doing Mechanical Equipment Co., Ltd.
Cold pressed soybean oil machine full production line with refinery .
Cold pressed soybean oil machine 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.
We have three types soybean oil presser machine:
Cold pressed soybean oil machine for pretreatment line.
Cold pressed soybean oil machine for refinery line.
About the details , welcome to contact us.
Basic information about whole line for soybean oil presser machine:
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.
