High Quality Crude Sunflower Oil Refining

High quality Crude sunflower oil refining

1.The Crude sunflower oil refining is used for removing the impurities of oil, such as, fatty acid, phosphatide, metal ion, pigment, oxide, solid particle and volatile gas.  It suitable for refining various crude oil, vegetable oil, such as sunflower seed oil, tea seed oil, groundnut oil, cottonseed oil, rice bran oil, soybean oil, corn oil and palm oil,etc.

2.The Crude sunflower oil refining can adopts chemical refining and physical refining, and the chemical refining includes batch refining, semi-continuous refining and continuous refining.

2. Main equipments of Crude sunflower oil refining:

1.Neutralization Tank: used for acid refining, alkali refining or washing.

2.Bleaching Tank: used for bleaching oil & removing pigment.

3.Deodorizing Tank: used for removing the odour of oil (made of stainless steel).

4.Conduction Oil Furnace: provide production with heat source, and the temperature can reach 280 °C.

5.Vacuum Pump: provide vacuum degree for bleaching & deodorizing process, which can reach above755mmHg.

6.Air Compressor: weather bleaching earth used in the bleaching process.

7.Filter Press: filtrate the bleaching earth.

8.Steam Generator: produce steam for deodorization and distillation process.

9.Leaf Filter: filtrate the bleaching earth & impurities. 

3. The refinery methods of Crude sunflower oil refining

1. Chemical refining

2. Physical refining

3. Chemical-physical refining

4. The final oil quality standard:

1. Grade one for salad oil

2. Grade two for high quality cooking oil

3. Mixture and volatile≤0.25%.

4. Impurity≤0.2%. 

5. AV (mgKOH/g)≤7
