The waste material enters the centrifuge, where the liquid phase is squeezed out and goes into the collection, and the solid into the drum, equipped with a fan. Water and alcohol vapors are condensed in a condenser and returned to the collection in liquid form. The dry residue from the drum is taken to the mill, the grains are fed to the extractor along with hexane from the feed tank pumped by the pump. Hexane miscella flows into the collection and is pumped through the filter into the tank. The meal enters the centrifuge and forth and the drum. Condensate vapor from the condenser is returned to the collection as well as the liquid phase from the centrifuge. The dry residue from the drum is removed. Miscella enters the evaporator, where the hexane in a thin film is distilled off and goes to the film rotary evaporator for final distillation.
