Description
Technical field
The present invention relates to a kind of extraction element, particularly a kind of triple-frequency ultrasonic extraction device and using method thereof.
Background technology
Because Chinese medicine has advantages such as special efficacy, safety aspect treatment, thereby be subjected to the world and attract attention, but ingredient complexity in the Chinese medicine, to the extraction of its active ingredient, be not only the primary link of Chinese medicine preparation, also be the prerequisite of Chinese medicine performance drug effect, therefore, the extraction of active ingredient is most important.Yet in the thousands of how tame herbal pharmaceutical enterprise of China, the leading technology of Chinese medicine extracts active ingredients is still continued to use and is soaked two kinds of extraction method and hot extractions.Exist extraction time long but soak extraction method, the recovery rate deficiency, efficient is low, if adopt hot extraction, then exist the multiple effective component can Yin Gaowen and destroyed, the high and dangerous disadvantage such as big of energy consumption, simultaneously, it is big that traditional handicraft has quantity of solvent, solvent recovery energy consumption height, and environmental pollution is serious.Therefore greatly waste Chinese material medicine resource and the pharmacological effect that has reduced Chinese medicine, restricted the development of herbal pharmaceutical engineering.
In order to address these problems, people attempt to adopt supercritical CO
2Extractive technique, supercritical extraction technique (SFE) is though the tool plurality of advantages, but be confined to lipophilicity, the less material extraction of molecular weight, technology high starting point, equipment complexity, invest relatively largely, the medicinal material treating capacity is little, is more difficult to get at general traditional Chinese medicine enterprise and applies.People have also developed microwave extraction method, but the depth of microwave penetration limited (with its wavelength at the same order of magnitude), simultaneously, non-polar solven does not absorb microwave energy, and has safety issue in operation and the use, makes this method restricted application.The research of relevant ultrasound assisted extraction technique is the domestic and international focus of research, studies show that in a large number, compares with conventional extracting method, have extraction efficiency height, extraction time short, extract that temperature is low, plurality of advantages such as wide adaptability and energy efficient.But the mode of single-frequency irradiation is mainly adopted in the research of extraction aspect at present, and extraction process exists " dead angle ", lack of homogeneity.
In the existing at home ultrasonic extraction device, all adopt a plurality of ultrasonic transduction heads of single-frequency to be installed on outer wall or oscillator places in the middle of the tank body.For the utility model patent of " 02212915.4 " a kind of ultrasonic wave extractor is disclosed as the patent No., charge door, drain hole, air inlet, gas vent are arranged on the tank body of extractor, be provided with the material division board in the tank body cavity, in the tank body cavity, be provided with supersonic generator.
The patent No. is equipped with ultrasonic head for the utility model patent of " 01267013.8 " discloses a kind of ultrasonic wave extractor at the bottom of jar, ultrasonic head also is housed in the side of tank body, and the ultrasonic head that is equipped with is equipped with protective cover.
The patent No. discloses a kind of ultrasonic wave extraction element for the utility model patent of " 200520001353.X ", comprise ultrasonic extractor, secondary settlement jar that ultrasonic probe is housed and feed liquid circulation line and the circulating pump that is connected extractor and settling tank, the ultrasonication probe is housed at ultrasonic extractor top, directly contact plant and extract, the ultrasonic power probe is housed outside the extractor sidewall, in the jar bottom filter septum is housed, under the dividing plate air jet system is arranged, make by fumarole uniform on the air jet system to be extracted material come-up, and liquid stream forms the turbulent flow endless form.Operation material non-blind area under action of ultrasonic waves in jar.
The patent No. discloses a kind of ultrasonic wave extractor for the utility model patent of " 200520022995.8 ", it comprises at least one combined ultrasonic transducer, described combined ultrasonic transducer is the immersion ultrasonic transducer, the cavity and the ultrasonic transducer unit that comprise a hollow, described ultrasonic transducer unit is fixed on the corresponding position of both ends of the surface inboard of cavity, with cavity resonance, be the ultrasonic wave of the three-dimensional ring of new ultrasonic vibration source thereby produce with cavity.
If same energy dissipation in a more wide field rather than concentrated energy dissipation efficiency can be more better on a probe, in order to obtain higher efficiency, in the existing at home ultrasonic extraction device, all adopt a plurality of ultrasonic transduction heads of single-frequency to be installed on outer wall or oscillator places in the middle of the tank body.More than these designs all can consider to be provided with probe quantity more, but the quantity of popping one's head in is restricted by the intensity of power, does not all consider from supersonic frequency.
