A system for extracting an oil from plant material, the system comprising: a gas moving device operable to propel a gas stream through the system, the gas stream being a stream of air or gas with or without entrained vapor, solids or droplets of liquid therein; a heater disposed such that the gas stream flows through the heater, the heater operable to heat the gas stream to a temperature sufficient to cause volatilization of an oil to be extracted; an extraction chamber having a receiving area for receiving plant material for extraction, the extraction chamber in communication with the heater such that the heated gas stream is directed through the receiving area, the heated gas stream volatizing the oil from the plant material such that the volatilized oil is disposed in the heated gas stream; a cooling chamber in communication with the extraction chamber such that the heated gas stream flows through the cooling chamber, the cooling chamber operable to cool the heated gas stream to or below a volatilization temperature of the oil such that the oil liquefies into droplets entrained in the gas stream, wherein the cooling chamber is a spray cooling chamber having a high pressure sprayer operable to spray collection solvent into the heated gas stream such that the collection solvent rapidly cools the heated gas stream to or below a condensation temperature of the oil; a collection chamber downstream of the cooling chamber and in communication with the extraction chamber such that that the gas stream flows through the collection chamber, the collection chamber operable to collect at least a portion of the extracted oil from the gas stream, wherein the collection chamber has at least one collection solvent sprayer; the at least one collection solvent sprayer, which is operable to spray droplets of collection solvent into the heated gas stream; and a liquid collector in fluid communication with a lower area of the collection chamber for collecting at least a portion of the collection solvent and extracted oil. a gas moving device operable to propel a gas stream through the system, the gas stream being a stream of air or gas with or without entrained vapor, solids or droplets of liquid therein; a heater disposed such that the gas stream flows through the heater, the heater operable to heat the gas stream to a temperature sufficient to cause volatilization of an oil to be extracted; an extraction chamber having a receiving area for receiving plant material for extraction, the extraction chamber in communication with the heater such that the heated gas stream is directed through the receiving area, the heated gas stream volatizing the oil from the plant material such that the volatilized oil is disposed in the heated gas stream; a cooling chamber in communication with the extraction chamber such that the heated gas stream flows through the cooling chamber, the cooling chamber operable to cool the heated gas stream to or below a volatilization temperature of the oil such that the oil liquefies into droplets entrained in the gas stream, wherein the cooling chamber is a spray cooling chamber having a high pressure sprayer operable to spray collection solvent into the heated gas stream such that the collection solvent rapidly cools the heated gas stream to or below a condensation temperature of the oil; a collection chamber downstream of the cooling chamber and in communication with the extraction chamber such that that the gas stream flows through the collection chamber, the collection chamber operable to collect at least a portion of the extracted oil from the gas stream, wherein the collection chamber has at least one collection solvent sprayer; the at least one collection solvent sprayer, which is operable to spray droplets of collection solvent into the heated gas stream; and a liquid collector in fluid communication with a lower area of the collection chamber for collecting at least a portion of the collection solvent and extracted oil.
