Sunflower seeds oil pressing machine with refining and dewaxing.
Sunflower seeds oil pressing machine is used to process sunflower seeds to edible oil. We have two methods to process sunflower to oil, one is mechanical press method , the other is solvent extraction method.
We have three kinds production line:
Sunflower seeds oil pressing machine with press line.
Sunflower seeds oil pressing machine with solvent extraction line.
Sunflower seeds oil pressing machine with refinery line.

Basic information about sunflower seeds:
Sunlower is high oil-content crop, mainly has two types: oil-sunflower and edible sunflower. Shell content of oil-sunflower is 29%-30%. And the seeds contents 40%-50% oil. In order to improve oil yielding rate and obtain high quality sunflower seed oil, the raw material should be treated as following processes: pretreatment, prepressing, extracting and refining.
Basic information about sunflower seeds oil pressing 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.Refining
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.
