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.
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.
Which hydraulic oil press machine is used to extract Sacha Inchi oil?
The hydraulic oil press machine (BY-180, Henan Beyrong Machinery Co.,Ltd., Shanghai, China) was used for extracting the sacha inchi oil (SIO). The machine, as depicted in Figure 1, consisted of a generator with adjustable pressure (0¨C55 MPa) and a pump controller. The maximum pressure used in this study was limited to ¡Ü50 MPa.
How to increase the yield of Sacha Inchi oil?
The yield of Sacha inchi oil can be increased by modifying the extraction method variables. For example, in supercritical CO 2, increasing the temperature from 40°C to 60°C and pressure from 300 to 400bar increases the oil yield from 43.60 to 50.10g oil/100g seeds (Follegatti-Romero et al. 2009 ).
