Vegetable oil refinery-physical refining

For capacity more than 20 tons per day , vegetable oil refinery adopts physical oil refining.Vegetable oil refinery plant with physical refining can adopt semi-continous vegetable oil refinery process or continuous vegetable oil refinery process.Capacity more than 50 tons per day vegetable oil refinery plant is using continuous oil refining.  From 30-50 tons per day, can be semi-continuous or continuous depending on your requirement.

Physical vegetable oil refinery:

♦Physical vegetable oil refinery process also has four basic steps: degumming, deacidification, decoloration and deodorization. The main difference between physical refining and chemical refining is   physical deacidification .
♦ Physical deacidification means using high temperature steam to remove free fatty acid with physical methods. In this process, it don't need add any alkali as chemical refining, no neutral reaction .
♦ Main deacidifaction machine in physical vegetable oil refinery plant is deacidifying tower

Features of physical vegetable oil refinery:
1. high oil yield , low vegetable oil refining losses.
2. Nearly no waste water
3. By product is fatty acid , with higher value than soapstock from chemical refining
4. Environment protection
5. Easy operation 

Application of physical oil refining:
1. For big capacity vegetable oil refinery plant , more than 20 tons per day.
2. For high acid value crude oil , such as rice bran oil ,palm oil
