Oil Extraction machine

Depending on different oil production process, edible oil extraction is divided into Directly oil extraction and Pre-pressed oil extraction.
1.  Direct oil extraction: also called" once extraction" , oil materials will be directly extracted after pretreatment ,which is used for low oil contain oil seeds.
2.  Pre-pressed oil extraction: Oil materials will be pre-pressed part of oil , and pre-pressed oil cake will be extracted , wich is used for high oil contain oil seeds.

Palm oil extraction is similar as palm kernel oil extraction, sunflower oil extraction and cottonseed oil extraction etc, adopts the pre-pressed oil extraction.The choice of palm oil extraction process and palm oil machine will effect oil quality , production consumption ,oil yield etc, so it's very important to choose one advanced and reasonable palm oil extraction process with good combination of palm oil machine.

Palm oil extraction process:

1.Oil extraction

A. Flow chart:  
Pressed palm oil cake→storage bin→closed screw conveyor→ solvent oil extractor→mixed oil /wet meal

B. Most important palm oil extraction machine is solvent oil extractor, there are many different types; oil extraction tanks, rotocel oil extractor ,loop type oil extractor, towline oil extractor etc.

                       Loop type oil extractor
Palm oil extraction-loop type oil extractor
                            Towline oil extractor
Palm oil extraction- towline oil extractor

2. Wet meal desolventizing and drying

A.  Flow chart:  
Wet meal→scraping conveyor→desolventizer→dry meal (cool down)→package
After oil extractor, wet meal contais about 25-35% solvent. In order to recover this solvent and get high quality meal , using high temperature steam to evaporate solvent .
B. Main plam oil extraction machine here is desolventizer

3. Mixed oil evaporation and stripping

A. Flow chart:  
Mixed oil filter→ mixed oil bin→ first evaporator→second evaporator→stripping tower→ extraced crude palm oil 
After oil extractor, mixed oil contains solvent , which need evaporate . Evapotation is using different boiling point between oil and solvent to make solvent transform into gas evaporated. 

B. Main palm oil extraction machine : multi-effective oil evaporator ( first ,second evporators and stipping tower combined)

4. Solvent condensing and cooling

A. Flow chart:
 Solvent gas → condenser → water separating bin →solvent recovery→ for oil extraction reusing

B. Main palm oil extraction machine : condenser
