Describe
The extraction of traditional Chinese medicine is an important traditional Chinese medicine production process unit operations, extraction system which uses directly related to the extraction efficiency of Chinese medicine extraction costs, and quality of Chinese medicine and clinical results after extraction.
The utility model aims to provide a retention cycle and temperature, greatly reducing solvent consumption, reduce extraction costs multifunctional medicine extraction system.
Aiming at the disadvantages of traditional centrifugal extractor, Zhengzhou Tianyi Extraction Technology Co.,Ltd. bring out CWL-M series centrifugal extractor, and own independent intellectual property rights , patent number :ZL2014205865573. Under the same handling capacity condition, this machine power consumption is only 10%~30% of traditional anular type, at the same time, short duration of this machine, split phase quickly, high extraction rate, save cost and solvent could be recycled and reused.
Traditional Chinese medicine extraction process:

Customization or not: Yes
If supply small test or pilot-plant test: Yes
Extractor working principle:


1.Mixing and mass transfer process:
Light and heavy liquor enter in the annulus mixed zone proportionally and from two different feed pipe orifice respectively, which formed by bowl and shell, with the help of bowl’s rotation, the two phases through turbine disc and impeller mixing and dispersing quickly, after mass transfer completely, to finish mass transfer process.
 
2. Two phases separation process
With the eddy-current disc help, mixture enter in bowl, at the compartment formed by board, the mixture is quickly synchronized with the bowl, under the action of centrifugal force, the larger density liquor moving away from the bowl center to the wall gradually in the upward flow; and the small density liquor doing the opposite, after clarification, two liquids enter into collection chamber with their own weir plate respectively, and drawn out by tigella, to finish the separation process.
Extractor advantages:
  Separation effect is obvious and large handling capacity;

●  Two phase materials contact with short time, and save extraction agent consumption and save cost;

●  High mass transfer rate, high stage efficiency, convenient start and stop, it can not break balance when stopped.

●  Cover small area, the cost of comprehensive investment is low.

●  Well-adapted, good flexibility, with intermittent operation, or single operation, or continuous counter current operation, and there is no need to add interstage pump.
