WHAT ARE THE REFINING MACHINES??
ABOUT REFINING:
1) Degumming: degumming process refers to the situation that dissolved phospholipid and viscose material are to be removed from the oil under high or low temperature by making them soluble in the water. Using phosphoric acid can facilitate the degumming process. Soluble phospholipid can be removed with the added water and nonsoluble phosphoric acid is very hard to remove, requiring the handling of concentrated acid to be removed. The choice of water and acid used in the degumming depends on the oil type.
2) Neutralization: NaOH is added to the degummed oil to make free fatty acid, phospholipid, and most of the pigment content become saponated subtance for the purpose of deacidification. generally, the neutralization process includes three steps: neutral soap separation, neutral soap washing and vacuum drying.
3) Decoloration: decoloration is to remove most of the pigment substances in the oil including colloid,trace amount of saponificaton and other impurities.
4) Deodorization: deodorization is the final step of the oil refining. this process uses steam stripping to remove smelly substances under the condition of vacuum and high temperature.
5) Dewaxing and winterlization: the purpose of it is to remove fog shaped solid substances existing in the oil of freezing temperature. those solid substances are made of saturated triacylalycero or waxiness.
