Jatropha curcas L. manufacturing

Jatropha curcas L. manufacturing

Some with metodhes can be used to extract oil from the fat of the material that presumably in oil or fat are rendering mechanical expression and solvent extraction. The method is suitable to Jatropha seeds mechanical expression.

Two methods are commonly used in Jatropha mechanical expression are hidraulic pressing and expeller pressing. In this project proposal, the chosen method is expeller pressing.

The points of the use of expeller press are as follows:

* The production capacity will be, because the pressing process can be done continuously.
* More time for an efficient, since it is not necessary to ascertain the extent and the warmth of the material.
* More rendemen produced.

Jatropha printing technique using the screw is the most advance technology and widely used in prosessing Jatropha oil industry today. In this way Jatropha seeds are pressed with a screw into continuously. Jatropha seeds are dry can be extracted directly into the screw press. This machine capacity is 100 litres per hour with rendemen level of 25%.
