1.It can enhance the strength difference between solvent and medicine and extract the effective components from the medi-cine to the maximum extent with high extracting rate.
2.It can make use of the forced circulation method to accelerate the diffusion of effective components.
3.With small solvent quantity,it can greatly reduce the energy consumption in subsequent procedure and reduce the produc-tion cost.
4.With continuous operation, the production efficiency is greatly enhanced and the automatic control is easy to be realized.
1.With pipe and modular extracting tank unit, each extracting unit can independently carry out extracting operation (leaching, dynamic extraction, high temperature extraction), and also can be combined (continuous counter-current extraction, periodic continuous counter-current extraction).
2.SpeciaI separating device is adopted to prevent the discharging being blocked.
3.Standard automatic operation bow can realize the automatic control of temperature, liquid medicine pH (optional), bow speed (optional) etc. key technological parameters, so as to guarantee the stability and reliability of continuous counter-current extracting technology.
4.Near-infrared online detection system can be allocated for the real-time measurement of content of effective components of traditional Chinese medicine for the convenience of optimizing the technological parameters.
5.Advanced traditional Chinese medicine manufacturing process analysis software platform and database management system can be allocated.
