Established in the early days of 1953, Henan Huatai is one of the best manufacturers and suppliers of oil processing machineries. We have gained great reputations in the oil making field with years doing business at home and abroad. You can trust the quality of our products as well as the services we offered.
ⅠPretreatment section of the Sunflower Oil Production Line
Pretreatment section removes impurities and adjusts temperature and moisture of oil seeds to suit further process.
Magnitic seperating→ Metal impurities
Husking→Sunflower seed hull
Prepressing→Crude sunflower oil
Sunflower seed cake→ Extraction Workshop
Same with other oil seeds cleaning, sunflower oil pretreatment workshop should be equipped with magnetic separator, cleaning seives, etc.
Sunflower seed have hard shells like peanut and palm kernel. Husking separates shells from sunflower seeds, which impoves oil yeild and oil quality.
c> Flaking :
Flaking destroy oil cells and increase oil surface, also shorten oil outflowing distance, which is benefitficial to extract oil and impove oil quality.
Cooking utilizes heat (steam or boiler) to degenerate protein facilite oil release.
e> Prepressing :
Sunflower seeds contain about 50% oil. Prepressing is needed to reduce oil content of sunflower seed cake to suit solvent extraction.
Ⅱ Extraction plant of the Sunflower Oil Production Line
Extraction plant utilize solvent to extract sunflower oil from sunflower seed. Oil residue of extraction plant is less than 1% .
Cake → Extraction→Wet Meal→Desolventising → Meal
Evaporating and stripping→ Solvent mixture →Condension and Recovery
Crude sunflower Oil Solvent Recycling
1>Extracting：To extract the oil in the cake by solvent, the general solvent is 6# extraction solvent oil or commercial hexane.
2>Desolventising: To remove and recover the solvent in the meal; Dry and cool down the meal at the same time.
3>Evaporating and stripping: Heating the the miscella by indirect steam, so that can vaporize the solvent and concentrate the miscella.
4>Solvent recycling: This process is to recover the solvent, decrease solvent comsuption, keep safety prodution and improve product quality.
Ⅲ Refining section of the Sunflower Oil Production Line
Refining section is to remove the impurities in the crude oil and improve oil quality.
Crude Sunflower Oil
Hot water→Degumming→ Oil Foot
Alkali liquor→ Deacidfying → Soap Stock
Activeted Clay→Decoloring → Waste Clay
1>Degumming：To remove the gum impurities, and prepare for the subsequent refining processes.
2>Deacidfying：To remove the free fatty acid in the crude oil.
3>Decoloring: To remove the pigment in the crude oil by adding active clay, so that can improve the oil quality.
4>Deodorizing：To remove the odor in the oil, so that can improve the flavor, stability, color and quality of the oil.
5>Dewaxing: To renmove the wax in the oil and improve the quality of the oil.
In general, sunflower oil refinery plant devides to 3 types, batch, semi-continuous, continuous sunflower oil refinery plant, the difference of which is capacity.
Our engineers can help you design and install sunflower oil extraction plant according to your capacity and requirements. If you want to know more about sunflower oil extraction plant, please feel free to contact us.
