Abstract
The improved ultrasonic Chinese medicine extracting equipment features the rod ultrasonic source set in the center, the outer circulating extracting and heating system, and the positive or negative pressure source. The present invention has the advantages of high ultrasonic energy utilization, high extracted liquid density, quick extracting speed, homogeneous heating, precise control and automatic squeezing of decoction dregs.
Description
Technical field
The invention relates to improvement to Chinese herbal medicine intensified by ultrasonic wave extraction element.
Background technology
The effective components of Chinese medicinal intensified by ultrasonic wave extracts, usually decocting boils extraction such as lixiviate, solvent extraction, steam distillation and has: extraction time lacks, extraction efficiency and extraction ratio height, energy consumption are low, production safety, can not destroy characteristics such as active ingredient, extracting solution pharmacological effect height, thereby is subjected to pay attention to day by day.Chinese patent 01223985 discloses a kind of intensified by ultrasonic wave Chinese medicine extraction jar, and its formation is the extraction pot inwall at the carrying vapour chuck, by hanger, the fixing some tabular ultrasound wave vibration plates towards tank body central authorities of suspension ring.Yet the tabular ultrasound wave vibration plate periphery of this employing wall built-up structure, the one, the ultrasonic machinery of opposed wall built-up can effectively all utilize, and interference of wave easily takes place, cause ultrasonic mechanical energy loss consumption, thereby the ultrasonic energy effective rate of utilization is low, extraction time is still longer relatively, and general extraction time needs 20-40 minute; The 2nd, tabular and wall built-up structure, surface abnormal shape, the perforate of tank body perisporium or pad and suspension member are more, clean complexity, and difficulty reaches the GMP requirement.Chinese patent 02213449 disclosed another kind of ultrasound wave Chinese medicine extraction jar is that several ultrasonic oscillators are sealed in the same transducing box, this transducing box is placed top in the extraction pot again, by setting up agitator, improves the ultrasonic effect of jar middle and lower part medical herbs.This structure is the same with above-mentioned patent, still can cause the ultrasonic energy loss, makes the ultrasonic energy effective rate of utilization reduce.And said structure, ultrasonic vibrator repair and replacement trouble.
Secondly, above-mentioned two kinds of supersound extraction jars all are to heat outward by chuck.Yet chuck heating, the one, power consumption is big, and the 2nd, medical herbs is heated and is difficult for evenly in the extraction pot, easily causes near tank body periphery medical herbs temperature height, central area temperature away from tank skin is low, easily causes case of thermal instability in the medical herbs, is easy to the destruction of the heat-sensitive substance of hydrolysis or oxidation.
Said extracted device besides, it is higher to discharge medicinal residues medicinal liquid content, needs by other measures medicinal residues are squeezed, and drains medicinal liquid, has increased the extraction operation sequence.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of structure more simple, clean easily, the ultrasonic vibrator repair and replacement are simple, the ultrasound wave Chinese medicine extraction device that the ultrasonic energy effective rate of utilization is high.
Another object of the present invention is to provide a kind of temperature control effective, the medical herbs temperature is even in jar, can not destroy the ultrasound wave Chinese medicine extraction device of medical herbs thermal sensitivity composition.
A further object of the present invention is to provide a kind of and can squeezes medicinal residues simultaneously, reduces the ultrasound wave Chinese medicine extraction device that deslagging contains medicinal liquid.
The present invention's first purpose realizes that main the improvement is to adopt the bar type ultrasonic oscillator, and it is arranged on extraction pot central authorities, to improve the ultrasonic energy effective rate of utilization to greatest extent.Specifically, ultrasound wave Chinese medicine extraction device of the present invention comprises extraction pot and built-in ultrasonic oscillator, it is characterized in that said ultrasonic oscillator is a bar type, is arranged on tank body central authorities.
The present invention's second purpose realizes, be between the extraction pot turnover, external circulation line to be set, make extracting solution outward by a jar outer circulation, and in the medicinal liquid closed circuit, heat exchanger is set, to the heating of circulation medicinal liquid, reach accurate temperature controlling and to keep temperature consistent by heat exchanger.
The present invention's the 3rd purpose realizes, it is characterized in that above extraction pot, being provided with malleation or the bottom is provided with negative pressure source, make extract finish discharge medicinal liquid after, by pressurization or negative pressure-pumping, the medicinal residues that are deposited on the extraction pot bottom are squeezed or negative pressure-pumping, the medicinal residues herb liquid is fully drained.Malleation of the present invention or negative pressure source, a kind of the easiest be to feed compressed air, or vacuum pump suction.
The present invention is owing to adopt the bar type supersonic source, and be arranged on tank body central authorities, not only the ultrasound wave loss of energy is little, active ingredient is under ultrasound field and cavitation effect combined effect in the Chinese medicine, can enter solution rapidly, it is fast to have an extraction rate, and general only the extraction needs about 15 minutes, both energy-conservation, improved supersound extraction efficient again; And easy cleaning simple in structure, the ultrasonic vibrator convenient maintenance and replacement.Extract medicinal liquid outer circulation dynamic extraction, and the outer circulation heating, fluid temperature is easy to control, and infringement destroys few to heat-sensitive substance, help protecting to case of thermal instability, be easy to the protective effect of active ingredient in the medical material of hydrolysis or oxidation, and can effectively save the medicine energy consumption; Secondly, the outer circulation dynamic extraction, more help contacting of liquid and medical herbs, favourable extractum extracts, and can realize that high concentration extracts, therefore can increase substantially solid-to-liquid ratio, solid-to-liquid ratio can reach 3/7, and high concentration is extracted, and also helps to save or reduce follow-up concentration process, both save investment, reduced operating cost again.Pressure or negative pressure source that tank body is provided with make and discharge medicinal residues behind the medicinal liquid under pressure or negative pressure-pumping effect, favourable the slag herb liquid are all discharged, and have not only improved extract yield; And omitted the bottom to the medicinal residues squeezing process.
Below in conjunction with several indefiniteness embodiment, further specify structure of the present invention, but embodiment not a limitation of the invention.
