The invention discloses a multifunctional volatile oil distilling and extracting tank, and belongs to the field of traditional Chinese medicine extracting equipment. The multifunctional volatile oil distilling and extracting tank comprises a tank body, a tank cap, a tank bottom and a steam supply system, and the tank cap is connected with an oil outlet pipe. The multifunctional volatile oil distilling and extracting tank is characterized in that the tank body is in the shape of a big-end-up cone, the tank body and the tank bottom adopt interlayers, steam is pumped into the interlayers, multiple layers of detachable separation plates are arranged in the tank body, and through holes are formed in the separation plates. The multifunctional volatile oil distilling and extracting tank can be used for extracting general medicinal oil and essential oil according to the routine and normal pressure, extracting high-boiling-point medicinal oil and essential oil containing aldehydes and alcohols at high temperature and high pressure, extracting medicinal oil and essential oil which are prone to volatilizing andloseand contain more alkenes in a vacuum decompression mode and extracting extracts, one tank has multiple purposes, distilling can be completed for one time, the equipment cost is saved, and the yield of the materials, especially volatile oil, is improved.
