Extract mixing tank

The invention discloses an extract mixing tank and relates to the technical field of pharmaceutical equipment manufacturing. The extract mixing tank comprises a tank body which is provided with a stirring device connected with a driving motor, a jacket is arranged outside the tank body, a steam connecting pipe and a condensate discharging pipe are mounted on the jacket, the steam connecting pipe is connected with a steam pipeline through an electromagnetic valve, a temperature sensor is mounted on the tank body, and the temperature sensor and the electromagnetic valve are electrically connected with a controller. Compared with the prior art, the extract mixing tank has the advantages that thick extract in the tank body is heated by injecting water vapor into a cavity between the jacket and the tank body, so that viscosity of the thick extract is lowered while fluidity of the same is improved, and the thick extract is easy to mix and stir uniformly.
