cwl type centrifugal extraction machine as the extraction of traditional Chinese medicine extraction equipment plant ivy extract

Ivy for five plus ivy genera plants, ivy in the plant medicine, its fruit ( Ivy) Also for medicinal, cosmetic mainly adopt them dry leaf. Ivy extract is a kind of essential oil from plant leaves extract. The extract capsule and liquid form, it can be found in a lot of ointment and cream. Ivy is native to southern Europe, not to be confused with each other South American poison ivy.
. cwl machine type centrifugal extraction to extract the ivy extract the separation principle of
. 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 through the bottom of the drum at the center of the channel into the � � drum 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.
in the ivy league after crushing, alkalization, extraction, ivy alkali mainly dissolved in the water extraction liquid; After adjust pH, ivy alkali free out from the water, then using chloroform extraction, alkali into chloroform as ivy, then continue to complete follow-up purification crystallization 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.
