This is one of our project in Philippine – a medium scale copra oil mill, including 20TPD oil extraction line and 10TPD oil refinery line. The daily capacity is processing 20 tons of copra (desiccated coconut) and get 10 tons of refined coconut oil. It is designed for manufacturing edible coconut oil from desiccated coconut (copra).

The following photos were took during the project construction onsite. If you are interested in getting more about the equipment details and cost of the project, just feel free to contact us (firstname.lastname@example.org)!
Copra Oil Pressing Process
Main Copra Oil Mill Machine in the Project: hammer mill, flaking mill, steam cooker, large screw press, oil settling tank, centrifugal filter, elevator and conveyor, etc.
Copra is large block dried coconut. The size of some large pieces can reach 180cm × 100mm × 6mm. For the crushing of copra, hammer mill is chosen. Increase the mesh size and reduce the number of hammer, hammer cross-arranged evenly. Since the copra is high oil-bearing material, chain elevator is used for transporting the materials after crushing. In addition, due to the high powder degree, the inlet and outlet can be easily assembled and even blocked. Therefore, there are observation Windows in the inlet and outlet.
- FAQs: Because of the constant stirring of steam cooker, oil is easily extracted and drop down through the spindle, causing waste and workshop environmental pollution. At the same time, the materials will caking the causing conveying difficulties.
- Solutions: reduce the powder degree of the crushed materials, reduce the mixing time and clean the feed downpipe in time.
- Steam pressure: 0.6 Mpa (indirect steam)
- Cooking time: 30 ~ 40 min
- Discharging temperature: 100 ° C

Oil Clarification and Filtering
Copra is high in fiber content, so the crude oil generally contains more slag. In order to reduce the burden of filter equipment, clarification process is arranged before filtering. The sludge go back to screw press again directly. The clarified oil will be sent to filtering process and crude coconut oil will be finally obtained.
In addition, the melting point of crude coconut oil is 19 ~ 22 ° C, so it will solidify at room temperature. To avoid troubles in storage and transportation, heating device is installed in the oil filtering poor and oil tank. It should be noted that the heating temperature must be good controlled.
