Biodiesel Production and Applications

This work is focused in the study of the oil yield extraction from castor seed using three different seed states called: whole, broken and bare endosperm. Taguchi design was used to determine the contribution of the followed parameters: seed state, amount of seed in the extractor, temperature and pressure. It was proved that it is necessary to introduce the whole seed and that the pericarp forms paths that increase the yield extraction. The contribution of the control factors has a yield extraction limit. The complete analysis was done using a surface response methodology giving as result the best parameter for temperature and pressure that allows a better yield mechanical extraction. According to these tests, oil yield can be increased by 35% or even more just by controlling those factors that generate higher variability during the extraction process.
