The present invention relates to an extractor using CO2 gas, and in particular to an extractor using CO2 gas capable of achieving a high purity and better extracting effect by a natural flow of CO2 gas induced using a pressure difference in the interior of a circuit without using a certain pump for inducing a flow of CO2 gas. The extractor using CO2 gas includes a CO2 gas storing tank for storing a CO2 gas at a certain pressure, a condenser connected with the CO2 gas storing tank for liquefying a CO2 gas supplied in a gas state from the CO2 gas storing tank, a liquid storing tank connected with the condenser for collecting the condensed CO2 liquid and storing the same, an extracting unit connected with the liquid storing tank and extracting an extraction object as the liquid CO2 is vaporized, and a gas and liquid separator connected in parallel with an outlet and an inlet of the extracting unit for thereby separating a liquid and CO2 gas from the extract. |
