Main Equipments: 

1. sunflower: It’s one of main oil seeds from human. It’s used to make sunflower oil around the world.

  The oil content in sunflower seed is about 30-45%.

2. Magnetic box: Clearing the iron impurity which might be in the sunflower seeds. The iron impurity will be harmful to the following machines, so we need take the iron impurities out. 

3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going through this part, most of the impurities are moved from sunflower seeds.

4. husking: Because there are shells on  sunflower seeds, it need to be husked. will help to get more sunflower oil from the seeds.

5. flaking:  It is the process of making use of the mechanical action to flake the sunflower seeds into flakiness. After flaking, the materials is becoming thiner thank before, it is good for absorb moisture and heat in cooking process , and it is much easier for getting sunflower oil in the oil press process.

6. Cooker: This machine can adjust the water content of the sunflower seeds. It’s also good for the press and oil extraction section.

7. Press: The press machine is used to take parts of the oil in the sunflower. when the capacity is low. It is not needed in the sunflower oil extraction way. If you using solvent extraction way to get sunflower oil, the flake can be sent to oil extractor directly from cooker.

Main Equipments:

1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.

2. Roary extractor: spray and soak the soybean cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).

3. DTDC: used to separate the solvent from the wet meal.

4. Miscella tank 1st: pump the miscella ( oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.

5. Miscella tank 2nd: the purified miscella will be pumped into it.

6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.

7. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.

Crude sunflower oil → degumming and deacidification→ decolorization →deodorization → refined sunflower oil.

Main Process:

1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the sunflower oil. 

One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for capacity from 30-2000T per day.

2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the sunflower oil according to the requirement of your market.

3. Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined sunflower oil.
