Abstract
A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control. In some examples, selected vaporized compounds are waste exhausted as vapor by bypassing the centrifugal electrostatic precipitator at specific known vapor temperatures, thereby eliminating potentially toxic or undesirable oils or compounds from being collected.
