Essential oils, such as CBD oil, are extracted from biomass, such as hemp, in a continuous process. The biomass is delivered to the upper end of a vertically oriented extraction chamber, while a solvent is injected at the lower end thereof. As the solvent flows upwardly, the oil is removed from the biomass. The resulting liquor is collected and purified.
