Description

TECHNICAL FIELD

[0001] The utility model belongs to liquid separation and pure technology field especially, relate to a kind of electrophoresis auxiliary ultrasonic collaborative supercritical extraction and synchronous purification device. BACKGROUND

[0002] In the growing awareness of health, the concept of medicine and food is gradually accepted by the public, and becomes an important force to promote the development of modern nutrition and health industry. However, ordinary medicinal materials and food materials have more impurities, which are not easy to be absorbed by human body, and are difficult to store for a long time, carry inconveniently, resulting in low utilization rate of these medicinal materials and food materials, difficult to extract ingredients, causing great waste.

[0003] The main purpose of extraction is to separate and extract specific components from a mixture. Extraction uses the difference in solubility of different substances in solvents to extract target compounds from the original sample, so as to achieve the purpose of separation and purification.

[0004] Traditional extraction methods include solvent extraction, ultrasonic extraction, microwave-assisted extraction and enzyme extraction. However, the extraction efficiency of solvent extraction is low, the extraction time is too long, and the heat effect on raw materials may damage the active ingredients and activity; the penetration depth of microwave in microwave-assisted extraction is limited (of the same order of magnitude as its wavelength), and its mass transfer function is not obvious in the process of strengthening extraction; ultrasonic vibration in ultrasonic extraction makes the material easy to break, although it can improve the extraction efficiency of raw liquid, but fine powder is easy to block the equipment, the maintenance cost is relatively high in later period, and the equipment investment is high, the operation is complex, and the applicable plant materials are limited. There are many influencing factors in enzyme extraction, the extraction process is complex, the extraction time is long, and the extraction rate is not high. It can be seen that the above methods cannot achieve ideal extraction effect.

[0005] Supercritical fluid extraction is an advanced physical extraction technology, which combines traditional distillation and organic solvent extraction, uses supercritical CO2 as solvent, and effectively separates, extracts and purifies matrix and extract. Supercritical CO2 has diffusion coefficient similar to gas and solubility similar to liquid, and its surface tension is zero, which can quickly penetrate into solid material. In supercritical state, supercritical fluid is contacted with the material to be separated, so that it can selectively extract components with different polarity, boiling point and relative molecular mass, and has the characteristics of high efficiency, not easy to oxidize, pure nature, no chemical pollution, etc.

[0006] Based on the above advantages, we propose a kind of electrophoresis auxiliary ultrasonic collaborative supercritical extraction and synchronous purification device. Utility model content

[0102] A kind of electrophoresis auxiliary ultrasonic collaborative supercritical extraction and synchronous purification method is based on the above-mentioned electrophoresis auxiliary ultrasonic collaborative supercritical extraction and synchronous purification device, including the following steps:

[0103] The material is fed into the extraction reaction kettle 9 through the feeding device;

[0104] The liquid carbon dioxide extraction liquid is provided into the extraction reaction kettle 9 using the supercritical liquefied carbon dioxide supply device;

[0110] The working principle of the utility model is as follows:

[0111] Unlike the conventional supercritical extraction method, the supercritical carbon dioxide in the utility model is still in a liquid state when it is input into the extraction liquid reaction kettle, and the action of the pressure reducing valve 26 makes the liquid carbon dioxide gradually convert into supercritical carbon dioxide, and the diffusion rate can reach about 100 times that of the liquid state, realizing large-scale extraction of the raw material components.

Under the action of the ultrasonic wave, the cell wall of the raw material is destroyed, and the internal active ingredients can be rapidly released into the supercritical carbon dioxide solvent for preliminary extraction. The thermal effect generated at the transducer and ultrasonic amplitude device will heat a part of the liquid carbon dioxide, combined with the controllable heating disc and the temperature controller, so that the liquid carbon dioxide is kept at a suitable temperature, and the active ingredients of the raw material are further extracted.

[0112] Meanwhile, the powder-like particles generated by the pretreatment and crushing of raw materials and the heavy metal pollutants possibly brought by the raw materials can be adsorbed to the vicinity of the corresponding polarity by the electrophoretic characteristics of the powder particles and the charging characteristics of the heavy metal elements themselves with the aid of the auxiliary electric field of the electrophoretic auxiliary electrode member, and then transported into the impurity collection cavity by the recovery pump to achieve the effect of synchronous purification. The supercritical carbon dioxide in the recovery pump and the pressure reducing valve 26 is gasified and separated, and the powder impurities are precipitated and collected in the collection cavity. Part of the gasified carbon dioxide can re-enter the reaction kettle through the raw material input valve 10 to adjust the pressure in the reaction kettle. The purified extraction liquid passes through the membrane filter to further remove larger particles of raw materials, and then enters the extraction liquid separation tank. Combined with the outlet valve, the pressure in the separation tank is adjusted to make all the supercritical state carbon dioxide gasify, and then return to the storage tank through the pipeline and the recovery valve, while the extraction raw liquid enters the collector to complete the electrophoretic auxiliary ultrasonic cooperative supercritical extraction and synchronous purification process.
