PROBLEM TO BE SOLVED: To provide a method for effective extraction of a safe essential oil from a fruit skin of a citrus and for utilizing the fruit skin of the citrus that has been handled as an industrial waste as an effective resource. SOLUTION: A closed casing 6 is equipped with an input port 8 for a residue remained after squeezing a fruit juice from the citrus, and a first suction port 15. A temperature in the casing 6 is elevated by a heating means to evaporate water and the essential oil from the residue. A condenser 85 cools and condenses water and the essential oil that are sucked from the first suction port 15 and evaporated in order to exhaust a condensate. A closed reservoir 90 stores the condensate from the condenser 85 and is equipped with a second suction port 94. A vacuum pump 96 (a vacuum means) sucks air through the second suction port 94 to evacuate the casing 6. A electric motor 33 (a rotation means) rotates a driving shaft that is closely inserted to a shaft inserting hole set in the casing 6. The driving shaft is equipped with a stirring blade to agitate and grind the residue. COPYRIGHT: (C)2007,JPO&INPIT
