PROBLEM TO BE SOLVED: To provide a steam distillation device capable of efficiently obtaining an essential oil better than the prior art from a stock solution prepared using naturally derived base material as a raw material.SOLUTION: A steam distillation device 1 comprises: a rotation cylinder 5; a distillation chamber 2 having an internal wall surface 4 surrounding the cylinder 5; stock solution supply means 101 introducing a stock solution into the distillation chamber 2 and supplying the solution to the upper part 21 of the internal wall surface; first heating means 103 heating the stock solution flowing down an internal wall surface portion 22 facing the outer peripheral surface 6 of the cylinder 5; stock solution derivation means 108 deriving the stock solution flown down the internal wall surface portion 22 and passed the internal wall surface portion 22 to the outside of the distillation chamber 2; a gas shielding member 109 closing a hollow part 50 so that steam does not pass the hollow part 50 of the cylinder 5; condensation means 105 deriving and condensing steam from the inside of the distillation chamber 2; a stock solution reservoir part 107 temporarily reserving the stock solution passing the internal wall surface portion 22 and reaching the stock solution derivation means 108; and second heating means 104 heating the stock solution reserved in th stock solution reservoir part 107. |
