Screw press extraction is a cost-efficient method, requiring a shorter extraction time than solvent extraction process and leaving no solvent residues in the oil product. Here, a single screw press machine at different press head temperatures was used to extract oil from Sacha inchi seeds.
Can screw expeller cater massive Jatropha biomass for oil extraction?
This study is aimed to make efficient screw expeller to cater massive Jatropha biomass for its oil extraction. A computational flow dynamics (CFD) simulation is performed to estimate the pressure developed inside the barrel through screw pressing when the feedstock is Jatropha seed.
Does ultrasonic extraction improve Sacha Inchi oil yield?
The results indicated that there was no significant difference in the oil yield of the sacha inchi samples among the various extraction methods ( p > 0.05). However, the extraction time required for ultrasonic-assisted extraction (UAE) and conventional extraction (CE) using n-hexane and ethanol was approximately double that of HCPE.
How to improve oil expeller for Jatropha seed?
Experimental validation of the simulation is used to improve oil expeller for Jatropha seed by fabricating the expeller after the analysis of design by ANSYS FLUENT codes. An oil yield in excess of 98%, as compared to a maximum 75% for existing screw expellers, was achieved in practical runs which is very promising.
