Sunflower oil extraction machine

 1. General Introduction:

    Sunflower oil extraction 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 sunflower oil extraction machine:
Sunflower oil extraction machine press line. 
Sunflower oil extraction machine solvent extraction line.
Sunflower oil extraction machine refinery line.

2. Basic information about sunflower seeds:
Sunflower 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.

3. Basic information about our sunflower oil extraction machine:


1).Pretreatment and prepress.

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

2) Solvent Extracting:

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

3) Refining

Crude Oil--Hot water--Degumming--Deacidfication -- Decolorization --Deodorizing--Dewaxing--Refined Oil

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.
