50–1500 TPD · high oil recovery with full SCADA automation.
Solvent extraction is the most efficient way to recover oil from oilseeds and from the residual cake left after mechanical pressing. Prepared, flaked seed is washed counter-currently with food-grade hexane in a percolation extractor, where the solvent dissolves the oil to form a liquid mixture called miscella.
The miscella is distilled to separate clean oil from the solvent, while the de-oiled meal passes through a Desolventiser–Toaster (DT) that heats it with steam to strip and recover every last trace of hexane. Efficient condensing systems recover well over 95% of the solvent, keeping the process economical and environmentally sound.
Aditya Engineers designs, builds and commissions complete solvent-extraction plants from 50 to 1500 TPD — engineered for high oil recovery, low solvent loss and precise, repeatable SCADA control.
Cleaning, cracking, flaking and heating the seed for optimum extraction.
Hexane percolates through the seed bed, dissolving the oil into miscella.
The oil–solvent mixture is distilled to recover clean crude oil.
Steam strips residual solvent from the meal and conditions it.
Vapours are condensed and the hexane is recovered and reused (>95%).
