Oilseed Extraction Process

The extraction process is the most important section in the oil productive technology by using the extraction method. The extraction principle is same no matter what the kind of raw material is processed.
A process for the extraction of oilseeds which comprises steps for extracting oil from oilseeds by contacting the seeds with an isopropanol-based solvent in an extractor to obtain an extract miscella of seedoils in solvent and a seed meal containing absorbed liquids, cooling and phase-separating the miscella to recover solvent, mechanically draining at least a portion of the absorbed liquids from the meal, evaporating residual solvent from the drained meal, and recycling drained liquids to the extractor as solvent.
