Coconut oil or copra oil, is an edible oil extracted from the kernel or meat of mature coconuts harvested from the coconut palm (Cocos nucifera). Copra, the dried kernel is the chief commercial product from coconut, which is mainly used for oil extraction. Copra normally has an oil content varying from 50 to 60 percent. For the extraction of oil from copra, the efficient system is by the use of automatic oil press machine.
 
Flow chart of coconut oil production line:
copra →cleaning→ drying →crushing→softening→ pre pressing → twice pressing →filteration → crude oil tanks → refinery section → refinery coconut oil 

1. Copra conveying: The raw material copra are blocks, so they are not suitable to be delivered by elevator.

2. Crushing: Copra is big block dried coconut meat, whose size can be 180mm x 100mm x 6mm.

3. Flaking: Copra is a high oil content material. if the rolling distance is too small, it is easy to get oil.

4. Steam cooking: Due to the continuous stirring of steam cooking machine, the oil tend to flow out from the copra, and drip down along the principal axes, resulting in waste and workshop environment pollution.

5. Pre-press: Press the cakes to leave oil 16%-18% in the cake. The cake will go to extraction process.

6. Twice press: Press the cake till the oil residue is about 5%.

7. Filteration: filtrating the oil more clearly then pump it to crude oil tanks.

8. Refinery: Degumming & nreutralization and decolorization, and deodorization. Reduce the FFA content to get the better quality of the finished oil, increase the storage time.
