Push the materials barrel right under the pressing plate. Turn the valve to the down mode, switch to manual mode and start the motor of the walnut oil extraction machine. The cylinder starts going down to enable the pressing plate to press the materials in the barrel. When the oil starts to flow out, switch to automatic mode.
How is walnut oil extracted?
Martínez et al. ( 2008) utilized a screw press to extract walnut oil, followed by the supercritical fluid carbon dioxide. The highest oil extraction efficiency was obtained in moisture content of 7.5% and temperature of 50°C with 89.3%.
Can cold press mechanical system extract Walnut & sesame oil?
However, little research has been done with regard to the extraction of walnut and sesame oil using cold press mechanical system. Furthermore, no data on the effect of various process parameters on extraction efficiency, oil profile analysis, modeling, and process optimization have been reported.
How to extract oil from Sesame & Walnut?
An oil extraction system based on the cold method for sesame and walnut oil extraction was developed in this study. The cold press system was used to successfully extract oil. The amount of extracted oil increased as the amount of applied pressure increased.
