Solvent extraction process include: extraction,desolventizer,Evaporative system, condenser.

Oil extraction, can be regarded as solid - liquid extraction. It’s use solvent has different solubility for different raw material to separate oil from the cakes.

Affect the leaching effect factors are

a. properties of the cakes, b. thickness of cakes. C. temperature in extractor d. moisture of cakes f. Infiltration of solvent or mixed oil. g. height of the material layer h, mixed oil concentration

I extraction time. j solvent ratio k solvent spray type

Therefore, high requirements for leaching equipment quality, our factory R & D of rotocel extractor and chains type extractor, which could meet all the requirement, with high oil yield, low solvent consumption, low consumption indicators. To ensure the quality of the oil. And bath spray type is our patent which is more effective spray way.

Generally Refinery process are Physical and chemical refining include Deodorization, degumming,deacidification, decoloring, dewaxing,

1.Deodorization is use the different volatility between Odor substance and triglyceride in vacuum high temperature to remove the smell.

2.Degumming is remove the Phospholipid in the crude oil. mainly use washing degumming method

3.Deacidification is remove fatty acid from crude oil generally use Alkali method

4.Decoloring use adsorption method to remove the pigment,soap, Phospholipids, polycyclic aromatic hydrocarbon, pesticide residues. in the crude oil

5.Dewaxing is cooling and crystallization to remove high melting point wax and high melting solid fat in the crude oil. then filtering and Centrifugal separation to separate it out. generally use equipments are Crystal tower, crystallization tank and diatomite processing tank
