Sunflower oil expeller machines for a mechanical press line Sunflower oil expeller machines 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 oil expeller machines press line.  Sunflower oil expeller machines solvent extraction line. Sunflower oil expeller machines refinery line About the details , welcome to contact us.   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 oil expeller machines.   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.   Pictures of prepress machines:   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.   Picture of solvent extraction machines:   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.   Pictures of refinery line:   Refined sunflower oil quality:
