Fuente: WIPO "essential oil or extracts" A system and method of extracting fluids from biomass material through the use of closed system capable of both low pressure and pressurized extraction that utilizes a combined vacuum and fluid collection tank, thus enabling different levels of pressure and vacuum to achieve a wide range of temperatures and allowing for variations in the chemical properties of the resultant extracted fluid. Although vacuum is preferred for safety, pressure is available when necessary, such as due to higher levels of filtration in which the use of vacuum is insufficient.
