JATROPHA CURCAS L. Manufacturing Process

•

Some metodhes with can be used to extract the oil of fat from the material suspected to contain oil or fat are rendering, mechanical expression and solvent extraction. The methode suitable to jatropha seeds is mechanical expression.

Two ways usually used in Jatropha mechanical expression are hidraulic pressing and expeller pressing. In this project proposal, the chosen way is expeller pressing .

The points of using expeller pressing are as follows :

Production capacity will be more because pressing process can be done continuously.
More time -efficient since there is no need to cut the size and heat the material.
More rendemen produced.

Jatropha pressing technique by using screw is the most advance technology and widely used in Jatropha oil prosessing industry today. In this way, Jatropha seeds are pressed with a screw goes in continuously. Dry Jatropha seeds to be extracted can be directly put into the screw press. This machine capacity is 100 liter per hour with rendemen level 25%.
