Description

A kind of extraction equipment

Technical field

The utility model relates to a kind of extraction equipment, and especially a kind of device that utilizes Non-Linear Vibration and critical extraction principle to extract can be applied to the extraction of Chinese medicine and plant.

Background technology

Chinese medicine is Chinese traditional medicine, and preventing and curing diseases with Chinese medicine has a long history in China.The World Health Organization also recommend to use traditional Chinese medicine to various countries, wishes that people can have safe, efficient, quick-acting, Chinese medicine easily.Yet because production technology, the especially extraction and separation process of Chinese medicine is relatively backward, be difficult to realize the standardization and the standardization of control of product quality, Chinese medicine is difficult to register in the international market always, legitimate sales and use.

In recent years, used sophisticated equipments such as the multi-functional extractor of stainless steel, outer circulation evaporation, multi-effect evaporator, fluidized drier during traditional Chinese medicine is produced.The formulation of Chinese patent drug is development to some extent also, has formulations such as granule, tablet, capsule and oral liquid.But on the whole, traditional extracting technique of Chinese medicine remains " pot liquor " decoction method basically, or at high temperature (more than 95 ℃) slightly extract with water and alcohol, and promptly " water extraction " or " alcohol extracting method " perhaps added low temperature drying and ultra-fine grinding.This traditional Chinese medicine processing method is owing to shortage science, strict process operating parameter, not only energy consumption height, efficient are low, and because high temperature is the necessary condition of extracting, thereby destroyed a part of active material in the medicine, can only extract part active ingredient, all the other active ingredients are destroyed in process of production, run off or remain in the dregs of a decoction discarded, not only influence the traditional Chinese medicine extraction rate, cause environmental pollution, and cause shortcomings such as curative effect instability, product colour taste difference and inherent quality instability.

Therefore, in traditional Chinese medicine research exploitation and industrialization process, supercritical liquid extraction technique occurred, it is to be applied to medicine to extract the newer technology in purifying aspect.Supercritical fluid dissolves with separating process material and just is supercritical fluid extraction (Supercritical Fluid Extraction is called for short SFE).General preferred CO ₂Carry out supercritical extract, its basic principle is: CO ₂Critical-temperature (Tc) be 31.05 ℃, critical pressure (Pc) is 7.38MPa, when being in this critical point when above, CO ₂Have gas and liquid double grading simultaneously.It both had been similar to gas, and viscosity and gas are close, was similar to liquid again, and density and liquid are close, was a kind of excellent solvent, can dissolve many materials by intermolecular interaction and diffusion.Simultaneously, in the zone of a little higher than critical point, pressure changes slightly, promptly causes the great changes of density, thereby causes the bigger variation of solubility.Therefore, supercritical CO ₂Can from matrix, substance dissolves be come out, form supercritical CO ₂The load phase reduces pressure or rising temperature, supercritical CO then ₂Solubility reduce, these materials just precipitation (parsing) come out, with CO ₂Separate, extract the purpose of separating thereby reach.Because different materials are at CO ₂In different solubility or same substance dissolving situation difference under different pressure and temperatures, make this extraction separation process have higher selectivity.

But, supercritical CO ₂Extraction also has the shortcoming that is difficult to overcome.At first, the cost of this extracting method is higher relatively, because CO ₂Under supercriticality, work, must use high-power air compressor, CO ₂Gas carries out compression cycle, and continues whole leaching process, causes the electric power energy consumption big like this, and cost is very high.Secondly, the gas under the high pressure all has certain danger, causes operating safety.And, supercritical CO ₂Solubility still not as liquid solubility big, make that the production efficiency of this extracting process is also relatively low.In addition, supercritical extraction technique relatively is fit to the extraction of one-component, but can not guarantee to extract one-component completely, extracts so also be not suitable for the full constituent of Chinese medicine or plant.

In recent years under study for action during the active ingredient of medicine and relevant plant, the CE of finding some Chinese medicine is better than the biologically active of wherein a certain pure product composition, and toxic and side effect is also little.A clear man of virtue and ability waits when end user's cervical cancer cell culture screens the active anticancer of Chinese medicine as Japanese scholar left side rattan, finds to have some class extract of active anticancer, and the purifying activity is high more more, toxicity is also big more simultaneously, and the activity of another kind of extract is very strong, avirulence, get over purifying, its activity is low more.The leaching speciality phase of rauwolfiae,radix takes for another example, does not have side effects such as the caused depression of cloudy reserpine.These have all illustrated a kind of biologically active pointer, and multiple composition acts synergistically each other and reaches.So no matter traditional high temperature extraction method is that water is carried or alcohol extracting, all can destroy original part active material in the medicine, may cause the generation of some toxic and side effect.And supercritical extraction technique can not guarantee to extract one-component completely, perhaps carries out full constituent and extracts, so certain limitation is also arranged in this respect.

In sum; there be serious the backwardness with not enough in the extraction process of Chinese medicine and relevant plant effective efficiency composition at present; research and exploitation have protection Chinese medicine and unlikely loss of effective components in plants and destruction; guarantee to extract the almost new process of full constituent simultaneously again; extraction for the almost full constituent of Chinese medicine, plant or other material has important theory and realistic meaning.
