The corn oil extraction machine, also known as screw oil press machine, is used for the mechanical pressing of corn germ oil. The corn germ oil press machine adopts directional pressure bearing and multi-stage propulsion to realize high oil yield.
How to extract oil from corn or maize germ?
The main methods to extract oil from corn or maize germ: Screw pressing and solvent extraction . "Screw Oil Pressing / Expelling" is the most used in small to medium scale corn oil manufacturing process. (At present, most corn oil companies or factories use screw pressing process, the oil yield is around 70%.)
How is corn germ oil extracted from milled corn germ?
Corn germ oil was extracted from milled corn germ using diluted aqueous ethanol as solvent. Batch extractions were carried out in 500 mL glass reactor vessels which were series connected with a constant temperature water bath machine (MP-501 A, Shanghai Yiheng Scientific Instrument Co., Ltd., China).
How to extract oil from corn germ during flour processing?
This work aimed the recovery of oil and protein fractions from corn germ (CG) generated as a by-product during flour processing. Several oil extraction techniques were investigated: hexane at room temperature, hexane at 45 °C, supercritical carbon dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.
