隨著超聲波提取技術(shù)的不斷發(fā)展,設(shè)備的自動(dòng)化程度不斷提高,再結(jié)合萃取對(duì)象的特性,將大大提高萃取效率,獲得更高品質(zhì)的萃取物,功率超聲萃取技術(shù)具有廣泛的應(yīng)用前景。

作為溶液凈化的一種手段,萃取法是利用化合物在兩種互不相溶(或微溶)的溶劑中溶解度或分配系數(shù)的不同,使化合物從一種溶劑內(nèi)轉(zhuǎn)移到另外一種溶劑中。與其他分離法相比,萃取法具有提取和分離效率高、試劑消耗少、回收率高、設(shè)備簡(jiǎn)單等優(yōu)點(diǎn),在濕法冶金、石油化工、環(huán)境保護(hù)等領(lǐng)域中得到越來越廣泛的應(yīng)用。
隨著我國(guó)科學(xué)技術(shù)的發(fā)展,實(shí)驗(yàn)室儀器行業(yè)隨之得以迅速發(fā)展,技術(shù)支持為產(chǎn)品升級(jí)換代提供了保障,實(shí)驗(yàn)室儀器也得到了更大的和發(fā)展空間。超聲波萃取儀作為萃取法廣泛的應(yīng)用設(shè)備,正迅速崛起,為科學(xué)實(shí)驗(yàn)服務(wù)。
超聲波萃取是利用超聲波輻射壓強(qiáng)產(chǎn)生的強(qiáng)烈空化作用、擾動(dòng)效應(yīng)、高加速度、擊碎和攪拌作用等多級(jí)效應(yīng),增大物質(zhì)分子運(yùn)動(dòng)頻率和速度,增加溶劑穿透力,從而加速目標(biāo)成分進(jìn)入溶劑,促進(jìn)提取的進(jìn)行。與常規(guī)萃取技術(shù)相比,超聲波輔助萃取具有快速、價(jià)廉、的優(yōu)點(diǎn),廣泛應(yīng)用在中藥材、食品、化工等領(lǐng)域。
Ultrasonic extraction is a multistage effect, such as intense cavitation, disturbance, high speed, crushing and stirring, which is produced by the pressure of ultrasonic radiation, increasing the motion frequency and speed of the material molecules and increasing the penetration of the solvent, thus accelerating the entry of the target into the solvent and promoting the extraction. Compared with conventional extraction technology, ultrasonic-assisted extraction has the advantages of high speed, low cost and high efficiency, and is widely used in traditional Chinese medicine, food, chemical industry and other fields.
隨著超聲波提取技術(shù)的不斷發(fā)展,設(shè)備自動(dòng)化程度不斷提高,再結(jié)合萃取對(duì)象的特性,超聲波提取技術(shù)將大大提高萃取效率,獲得更高品質(zhì)的萃取物。但同時(shí),超聲波萃取儀也會(huì)因超聲波的頻率、強(qiáng)度、萃取時(shí)間、萃取產(chǎn)物中的酶以及萃取溶劑的用量和濃度而受到影響,從而影響萃取物的終結(jié)果。
With the continuous development of ultrasonic extraction technology and the increasing automation of equipment, the ultrasonic extraction technology will greatly improve the extraction efficiency and obtain a higher quality extract. But at the same time, the ultrasonic extraction instrument will also be influenced by the frequency, strength, extraction time, enzyme in the extraction products, the amount and concentration of the extraction solvent, which will affect the final result of the extract.
現(xiàn)階段,我國(guó)超聲波萃取儀領(lǐng)域正加快步伐,研究新的萃取體系和工藝,開展萃取理論的探討,把重點(diǎn)放在研發(fā)新型萃取設(shè)備的自動(dòng)化、連續(xù)化上,朝著專業(yè)化、規(guī)范化方向邁進(jìn)。以此來減少超聲波對(duì)萃取物的影響,從而提高有效萃取率,更好的服務(wù)于科研實(shí)驗(yàn)項(xiàng)目。
另一方面,無論樣品是有機(jī)物還是無機(jī)物,超聲波萃取技術(shù)已顯出明顯優(yōu)勢(shì),但大多數(shù)實(shí)驗(yàn)室樣品用量較小,離工業(yè)化應(yīng)用還有一定的距離。因此真正實(shí)現(xiàn)超聲波萃取技術(shù)的工業(yè)化應(yīng)用,是今后技術(shù)發(fā)展應(yīng)重視的問題。
縱觀超聲波萃取儀發(fā)展情況,我國(guó)超聲波萃取技術(shù)正處于發(fā)展之中,前景可觀。未來,相信隨著科研水平的不斷提高,我國(guó)能在超聲波萃取技術(shù)研發(fā)方面取得重大突破,讓超聲波在分離提取領(lǐng)域更好地發(fā)揮作用。
