摘要：NOVELTY - The device has a filling tank provided on an upper part of a steam generator. The filling tank is provided with a porous filler and a guide pipe. A vapor uplink channel is arranged in the filling tank. An extracting agent containing pipe is located at a tail end of a steam ascending channel. A cooling pipe is located at an extracting agent tube. A raffinate reflux pipe is utilized for extending a lower end of a steam ascending channel downward from a connection interface to a steam condensation pipe. A discharging valve is connected with an agent placing pipe. USE - Steam distillation device. ADVANTAGE - The device can use gas-vapor distillation process to obtain high quality product, and saves water and extracting agent. The device has better practicability and economic usage, and is environment-friendly. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a steam distillation device in partial section.
