Abstract
An apparatus and method for extracting oils and fats from oil-bearing substances without using degrading temperatures. The apparatus may comprise an extraction chamber containing an oil-bearing substance, an oil-collecting chamber, a recovery pump, a first jacket adjacent at least a portion of the extraction chamber, and a second jacket adjacent at least a portion of the oil-collecting chamber. The method involves heating a solvent and reducing pressure to facilitate a low-temperature vacuum boil; delivering the heated solvent into the extraction chamber configured to facilitate the low-temperature vacuum boil of the solvent within the extraction chamber; pumping the solvent in vapor form out of the extraction chamber with the recovery pump; delivering the oil and fat extracted in the extraction chamber to the oil-collecting chamber; pumping solvent in vapor form out of the oil-collecting chamber with the recovery pump; and delivering the solvent received by the recovery pump to the first and second jackets to provide heat to the chambers.
