The invention discloses an efficient dynamic drug-decocting machine which comprises a machine body and a heater. The machine body is installed on a base, the top of the machine body is provided with an upper cover, and the machine body is provided with a sight glass used for observing drug decoction inside the machine body. The efficient dynamic drug-decocting machine is characterized in that a mesh basket is installed in the machine body of the drug-decocting machine, and the heater is installed below the mesh basket; the machine body is provided with condensing devices and a circulating system, and the condensing devices are connected with a steam outlet pipe of the upper cover at the top of the machine body and fixed to the outer side of the drug-decocting machine through a support; the circulating system is composed of a circulating pipeline, a high-speed pump and a circulating pipeline valve, an outlet pipeline is arranged on the liquid drug section below the heater and connected to the high-speed pump outside the machine body, and an outlet of the high-speed pump is connected with the circulating pipeline which penetrates through the upper cover at the top of the machine body to enter the upper portion of the machine body of the drug-decocting machine. The efficient dynamic drug-decocting machine can be widely applied to the aspects such as hospital pharmacies, out-patient departments, scientific research and teaching experiments, and a good market prospect is achieved.
