This principle of moringa oil extraction machine utilizes sub-critical solvent for the first extraction process that is known as counter-current extraction. The process involves treating of pretreated moringa seeds with propane and butane, which are classified as liquefied sub critical solvents. The end product from extractor are are extracted oil meal and mixture fluid. The mixture fluid yields to gassified solvent as a result of solvent gasification whereby the fluid is subjected to vacuum evaporation at normal temperature. A fresh recycling session is done after the gasified solvent is condensed or liquefied. The basis of utilizing the sub-critical low temperature extraction technology of our moringa oil extraction machine is that the boiling point of these solvent is below 0°C. When under low temperature and normal pressure condition, the soluble fatty acids and other active components within the raw material and solvents has the propriety of dissolvability. That is how this low temperature extraction machinery get the target products. The processes in this method are achieved with normal temperature and pres

 Outstanding feature of low temperature moringa oil extraction machine

• The sub-critical solvent extraction produces high-quality moringa oil since there is no heat in the extraction process. This also protects the natural active ingredients in moringa oil from undergoing oxidation reaction.
• The sub-critical low temperature moringa oil extraction machine requires low investment compared with supercritical extraction equipment under the same condition to produce upscale quality oils. This is due to the fact that the pressure is maintained in the moringa oil extractor and other extraction equipment is much less than that of supercritical extraction machinery, making it worthwhile for in small and large scale moringa oil production.
• The moringa oil meal is produced through low temperature desolventizing process, so there are no damages for the oil meal, providing good condition for further processing and development. More important, this low temperature oil meal is priced high in the market.
