The most two popular oil extraction methods today are using screw press(oil press machine) and using Chemical solvents, however, in order to squeeze the most oil . Garba et al. Results . The expression method of essential oil extraction is popular in many instances because it does not involve the use of a heat source, as does distillation. 1. Hydraulic pressing is generally influenced by the following independent operating parameters: the applied pressure, the peanuts initial water content, the compression speed, the pressing duration and the cake thickness (Lanoisellé 1995). Optimization of Mechanical Oil Expression from Sandbox (Hura crepitans Linn.) Direct solvent extraction is suitable for oil The general applicability of GAME was demonstrated with experiments with sesame, linseed, rapeseed, palm kernel and jatropha (hulled and dehulled) at 40 °C and varying mechanical pressures (10-70 MPa). Oilseeds processing by mechanical means involve a very low initial and operating costs compared to the solvent . Most nut and seed oils are also extracted using a " cold pressed " method but here oil is forced from the material under high mechanical pressure and generally produces a good quality oil, but some manufacturers do impair this good quality by excessively refining the oil after extraction by means of chemicals or high heat.
