10-50TPD semi-continuous sunflower oil refinery plant

10-50TPD sunflower oil refinery plant can be designed into semi-continuous sunflower oil refinery plant, which are suitable for medium scale sunflower oil refinery business.

Semi-continuous sunflower oil refinery plant has higher configuration than batch type sunflower oil refinery plant. The difference is the deodorizatin process, semi-continuous sunflower oil refinery plant using deodorization tower, which is automatic working, however, batch type sunflower oil refinery plant use deodorization tank, which need workers to operate.

At the same time, compared with full-continuous sunflower oil refinery plant, semi-continuous sunflower oil refinery plant needs less investment cost. And the deodorization tower in semi-continuous sunflower oil refinery plant is the same as that in full-continuous sunflower oil refinery plant. The quality of refined sunflower oil is the same, too.

Semi-continuous sunflower oil refining process detailed introduction:

1. De-gumming process in semi-continuous sunflower oil refinery plant:

Add phosphoric acid to convert non-hydrated phospholipids into hydrated phospholipids.

2. Deacidification process in semi-continuous sunflower oil refinery plant:

Add NaOH to react with FFA inside crude sunflower oil. Then use hot water to mix with crude sunflower oil to remove the gums and soap stock inside oil. At last dry the oil for bleaching process.

3. Decolorazation/Bleaching process in semi-continuous sunflower oil refinery plant:

Use the bleaching earth to absorb the pigments and impurities out. Then use the filter to remove the bleaching earth.

4. Deodorization process in semi-continuous sunflower oil refinery plant:

This is the main different section from batch type sunflower oil refinery plant. It’s continuous working. Use the continuous deodorization tower to remove the peroxide value. Then there will be no serious smell in sunflower oil. After filtering, you will get final oil product-refined sunflower oil.

5. Dewaxing process in semi-continuous sunflower oil refinery plant:

Dewaxing process is necessary for sunflower oil, in which there is very high wax content that are harmful to human health. In sunflower oil dewaxing process, the refined sunflower oil is heated first, then slowly cooled to crystallize, and finally the filter filters out the wax. We can get standard high quality sunflower that can be sold in supermarket.

The semi-continuous sunflower oil refinery plant has widely usage for many oilseeds. It can deal with different kinds of oil, sunch as cottonseed oil, sunflower seed oil, soybean oil, peanut oil, palm oil, coconut oil, etc. Engineers of Henan Doing Company can design according to your requirement.
