Our company is professional in sunflower oil extraction plant design, installation, trial run, technical training and so on. We can provide you turnkey project of the whole sunflower oil extraction plant from 10 to 6000TPD.

Sunflower oil has high nutritive value, containing about 90% unsaturated fatty acids,and the essential fatty acidlinoleic acid accounts for about 66%. In order to improve oil yield rate and get high quality sunflower oil, the sunflower oil extraction plant should consist of following processes: pretreatment, prepressing, extracting and refining.

1. Pretreatment section of the sunflower oil extraction plant

Pretreatment section removes impurities and adjusts temperature and moisture of oil seeds to suit further process. Sunflower oil pretreatment and pressing machine can extract most of the oil in the sunflower seeds.

Sunflower seeds

Magnitic seperating→ Metal impurities

Cleaning→Other impurities

Husking→Sunflower seed hull

Flaking

Cooking

Prepressing→Crude sunflower oil

Sunflower seed cake→ Extraction Workshop

2. Extraction plant of the sunflower oil extraction plant

Extraction plant utilize solvent to extract sunflower oil from sunflower seed. Oil residue of extraction plant is less than 1% . We can offer custom-made design. Layout design for customer’s plant, various configurations according to your needs.

Fresh Solvent

Cake → Extraction→Wet Meal→Desolventising → Meal

Miscella                                            ↓

Evaporating and stripping→ Solvent mixture →Condension and Recovery
↓                                                      ↓
Crude sunflower Oil          Solvent Recycling

Refining Workshop

a.Extracting:To extract the oil in the cake by solvent, the general solvent is 6# extraction solvent oil or commercial hexane.

b.Desolventising: To remove and recover the solvent in the meal; Dry and cool down the meal at the same time.

c.Evaporating and stripping: Heating the the miscella by indirect steam, so that can vaporize the solvent and concentrate the miscella.

d.Solvent recycling: This process is to recover the solvent, decrease solvent comsuption, keep safety prodution and improve product quality.

3. Refining section of the sunflower oil extraction plant

Refining section is to remove the impurities in the crude oil and improve oil quality.  In general, sunflower oil refinery plant devides to 3 types: batch oil refinery plant, semi-continuous oil refinery plant, continuous oil refinery plant. These 3 oil refinery plants are used for different capacity. But the processes in each oil refinery plant are almost the same.

Crude Sunflower Oil

Hot water→Degumming→ Oil Foot

Alkali liquor→ Deacidfying → Soap Stock

Activeted Clay→Decoloring → Waste Clay

Deodorizing

Dewaxing →Wax

Refined Oil

a.Degumming:To remove the gum impurities, and prepare for the subsequent refining processes.

b.Deacidfying:To remove the free fatty acid in the crude oil.

c.Decoloring: To remove the pigment in the crude oil by adding active clay, so that can improve the oil quality.

d.Deodorizing:To remove the odor in the oil, so that can improve the flavor, stability, color and quality of the oil.

e.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.
