Innovative manufacture techniques of Chinese medicine with ultrasound and porous resin

Ultrasound could be used to extract medicine materials from traditional Chinese herbs. And the macro-porous resin purification is an obvious biomaterial technology. The characteristics of ultrasound propagation in the mixture of biomaterials and liquor are researched for Chinese medicine extraction. And how to combine ultrasonic technique with macro-porous resin purification is discussed in the paper. To overcome some shortages of existing ultrasonic processors used for biomaterial extraction, a new structure and design method so- called self-circumrotation are introduced. A new machine system of multi-frequency and self-circumrotated ultrasonic cylinder, combined with the adsorbing cylinder of porous resin, has been integrated and applied in Chinese traditional medicine manufacture. It was examined via practice that there are three advantages with the design: (A) The ultrasound intensity is strong and symmetrical in all over the cylinder; and the cavitation yield is l.S-1.3not2.8 times relative to what of ordinary processors; (B) The medium circumrotation is automatically realized in the cylinder; (C) The static and active adsorbing cylinders of porous resin are more effective for medicine material adsorption and purification from complex prescription of traditional Chinese medicine.
