wind cane for menispermaceae plants ivy leaves and dry hair green vines, with functions of wet, the effect of main and collateral channels. Orientvine the main component of sinomenine, double sinomenine, magnolia alkali, pointed out the alkali etc. [ 1] , which is suitable for the main components of the anti-rheumatism sinomenine, pharmacological studies have shown that sinomenine for formaldehyde and 'egg white' arthritis of rats significantly fading effect, in addition to the analgesic action of mice and rabbits have certainly [ 2] 。
the orientvine extraction process is roughly as follows:

in orientvine after crushing, alkalization, extraction, sinomenine mainly dissolved in the water extraction liquid; After the pH, sinomenine free out from the water, then use chloroform extraction, the sinomenine in chloroform, � � � continue to complete follow-up purification crystallization after operation.
in chloroform extraction process, the traditional mode of operation is tank stirring extraction, artificial to separate two phase after stratification by gravitational force, the intermittent operation is more tedious, a longer production cycle. By using. cwl - M new centrifugal extraction machine can not only overcome the above shortcomings, but also can make the extraction period of continuous production, separating the two more completely, less dosage of chloroform, the advantages of higher extraction rate.

1. 2 separation principle
. cwl can use a single single-stage centrifugal extraction machine, also can use many sets of multistage. Single centrifugal extraction machine and its working process is as follows: the runtime raw material liquid and extraction agent from their inlet into the bottom of the machine, the high-speed rotating drum, two phase liquid into the complex vortex and turbulence state, full mixing and mass transfer. Then, in the rotating drum and fixed at the bottom of the form under the action of self-priming pump, impeller, the mixture after entering the drum drum at the bottom of the center hole inside; In block flow plate under the action of mixed liquid into the state of high speed rotating, dense phase, moving towards the drum wall, while the density of small to the central axis direction, after the separation of two phase out their discharging mouth finally, complete the mass transfer and phase separation process.
