Described is an extraction device for extracting compounds from plant material and a method for using such an extraction device. The extraction device comprises an extraction tank receiving plant material and dissolving soluble compounds inside the plant material into a solvent to form a micelle. A series of fluidly connected separation chambers separate purified compounds from the micelle, resulting in purified compounds in each of the separation chambers and solvent. A heat exchanger and a chilled reservoir are used for cooling and storing the solvent. A pump is used for pumping and circulating the solvent into the extraction device. Finally, a control system automatically controls temperature and flow in the extraction device.
