A liquid solid separator (1) utilizing inductive heating. An electrically conductive scroll conveyor (13) is contained within a non-magnetic and non-conductive housing (14) under vacuum. A moveable alternating electric coil (22) is disposed around the housing. The scroll pulls the solids through the housing. Operation of the coil (22) heats the scroll (15) which heats the solids. The vacuum lowers the boiling point of the liquids, and they are vaporized at a relatively low temperature. The vapors are condensed and collected. Because of the low temperatures, the separated liquids are less likely to deteriorate during separation, facilitating recycling. Thermocouples and a computer track the internal temperature of the separator and coordinate the position of the coil to maintain the desired temperature. The housing is provided with a heat insulating outer layer and the interior of the scroll is pressurized with nitrogen. The separator surfaces exposed to the atmosphere are maintained at or below 150°F.
