Abstract
A plant oil extraction apparatus may include a volatile solvent tank, an oil bearing plant material container for receiving at least some of the volatile solvent, a chiller for cooling volatile solvent to a liquid state in contact with the oil bearing plant material, a vessel for collecting at least some of the mixture of volatile solvent and plant material, a heater for heating at least liquid state volatile solvent to a gas state, a compressor for compressing volatile solvent gas to a higher pressure, and a heat exchanger to cool and condense at least part of the compressed solvent gas to a liquid state and to return at least part of the condensed liquid volatile solvent to the solvent tank. The cycling of the apparatus may at least in part be controlled by an electronic controller and a human machine interface may be used by an operator to input data to the electronic controller.
