the olive Crude Oil refinery for sale with high efficiency the pretreatment and prepress  of Oil material

oil pretreatment include several section as below:

a.cleaning section

b.breaking section

c.flaking section 

ftening section 

oking section 

f.oil press section

 crude oil refining, generally are Physical and chemical refining, include Deodorization, degumming,deacidification,decoloring, dewaxing

Method of  crude oil refinery :

1. Physical Refining

2. Chemical Refining

crude oil refinery process can be divided into:

1. Bacth oil refining

2. Semi-continuous oil refining

3. Continuous oil refining

Note:

For rice bran oil, sunflower oil and corn embryo oil need the dewaxing process.

The oil contains a lot of wax, which comes from the skin of oil seed.

For palm oil, it needs fractionation process, which can get the palmoil fluid at the different temperature.

Fractionation is the special treatment of palm oil, palm oil is to cool down to degrees and to maintain a certain time, the melting point of the components will become crystallized, 

can be filtered by the second "fractionation" into three different melting point of the product these three products are palm stearin melting point above 40 degrees, palm olein melting point of 30 degrees and 20 degrees about the liquid melting point of palm oil. 

1.Preheating secticon:

Pumping crude oil into hydrate tank (oil refining tank), on one hand, quickly stirring , on the other hand, heating by steam or heat transfer oil (in coil pipe), rise oil temperature.

 2.Degumming section:

 This is the most important section of hydrate de-gumming,manage the adding water (there is a little P-acid in the water) amount, temperature and add water speed.

 3.Deacidification section:

This part adopt alkali refining method, that is use alkalis like (NaOH) to neutral the free fatty acid in oil, during this process it will produce soapstock , then separated from the oil by setting several hours. NAOH solution, not only neutral free fatty acid, also can act with other matters like protein, mucus, phospholipid, pigment. 

4.Decolorization Section:

In normal situation , there is pigment in the crude oil , we need to using the active clay to absorb the pigment away ,we use the vibrating filter to filter the waste clay away . If you want to get light color oil , you need to add more active clay . That is mean , the customer can accord to his requirement to control the oil color.

 5.Deodorization and Dehydration Section:

Usually ,there are some odors in the crude oil , it affects the quality of the edible oil . About our refining process , we usually use the direct steam to take odors away in the vacuum condition . In the deodorization pot , the temperature is very high , it also can finish the dehydration section.

6. Filtering:

This process can remove off the small amount of unsettle gum soluble impurities in the degummed oil, after oil dehydrate cooling , filtering again, to ensure the product oil quality. Then pumping the final oil into the oil tank.

G.Dewaxing section:

After refining , there is a final process is required , that is De-waxing. Because there is some wax content in the sunflower oil , you need to remove it , or it will affect the quality of the  edible oil
