2.Main parts of the process of refined black pepper oil palnt:

3.Introduction of Degumming&Deacidification process

Degumming:

The purpose of degumming is to remove the phospholipid, sugar, protein, trace mental,

and some other impurities, which have bad effect on the stability of the oil.

Deacidification:

Add some certain quantity of alkali to neutralize the free fatty acids. During this

process, some soapstock will be produced.The soapstock will be separated from the

oil after using the centrifugal machine.

2.Main parts of the process:

3.Introduction of Decoloration process

Mix the oil with activated clay in the oil soil mixing tank, and 1 ton oil needs 5kg

clay. Then stir it 10 minutes at 10°C. Next, pump the mixed oil into the

decolorization tower. It use steam to heat the mixed oil at 100°C, and the process

lasts 30-40 minutes.

The third section: Deodorization

2.Main parts of the process:

3.Introduction of Deodorization process

The main purpose of deordorization tower is to remove fatty acid and some odor

material. The principle of the deordorization is to use the high temperature and

vacuum to remove the odor. The fatty acid and odor will be stalled in the storage

tank.
