Method of high-speed in particular batch production of aromatic essential oils from perfume-generating plants or from parts thereof such for instance as seeds, bulbs, flowers as well as a device for carrying out this method

Method for the high-speed production of aromatic essential oils from perfume-generating plants or parts thereof, which comprises simultaneously crushing said plants or parts thereof into fine particles and forming therefrom an aqueous slurry while still further simultaneously heating said slurry as it is being formed to a temperature sufficiently high to form water vapors with a high content in essential oils from said plants, subjecting the thus formed vapors to fractional rectification under substantially atmospheric pressure while preventing passage of solid particles, thereby concentrating the content of the essential oils therein to form enriched vapors, condensing said enriched vapors, thereby forming a condensate, recovering said condensate, removing the essential oils from said condensate, and recycling a portion of the remaining condensate free of essential oils to the retification step.
