Lub Hauv Paus Lub Ntsiab ntawm Ultrasonic Extraction Thiab Teeb Meem Muaj.

Thaum loj zog extraction ntawm ultrasonic yoj ACTS rau hauv nruab nrab, qhov kev vibration yog nyob rau hauv ib lub xeev ntawm nyias, nruab nrab yog nraus rau hauv ntau qhov me tej khoom khoom extraction, instantaneous yog kaw, cov me qhov mus txog rau phav phav atmospheric siab siab thaum kaw , tshwm sim cavitation tshwm sim. Qhov kev cuam tshuam ntawm ultrasonic rau kev rho tawm thiab kev sib cais ntawm ntau yam feem ntau yog los ntawm nws cov cavitation.

Cavitation nyob rau hauv lub siab zoo los ntawm lub cua me me npuas tawg mus rau lub tawg ntho ntawm tawg phab ntsa thiab tag nrho cov kab mob nyob rau hauv instantaneous, shortens lub sij hawm so thiab nyob rau tib lub sij hawm, qhov teebmeem ntawm lub siab ultrasonic enhanced tso tawm ntawm intracellular , diffusion thiab xaus, muaj peev xwm ho txhim kho qhov txiaj ntsim ntawm kev rho tawm. Cov txheej txheem ntawm ultrasonic crushing yog ib tug txheej txheem ntawm lub cev tsis muaj tshuaj lom neeg, thiab cov khoom bioactive yog khaws cia unchanged. Cavitation tshwm sim nyob rau hauv cov cua me me npuas hauv cov kua hauv cov kua hauv kev siv ultrasonic oscillation, kev loj hlob, ntsws thiab lub cev qhuav, thiab cov txheej txheem ntawm cov txheej txheem hauv lub cev qhuav dej ntawm lub sij hawm luv luv, tib lub sij hawm nyob rau ntawm cavitation npuas tsim kub thiab siab siab, tsis muaj zog poob siab thiab cua ntawm ntau tshaj 400 kmoh micro dav hlau, stripping, pitting nyob rau ntawm qhov ntawm cov khoom thiab crushing kev ua haujlwm tsim ib qho tshiab nto, qhov tshwm sim txuas ntxiv huab hwm coj hloov deg qhov chaw. Lub turbulent nyhuv tshwm sim los ntawm cavitation ua rau cov ciam ciam txheej nyias hauv cov kua-raug interface, uas ua rau txo qis hauv qhov concentration gradient ntawm kev sib tham hauv lub txheej txheej. Lub perturbation cov nyhuv tshwm sim los ntawm cavitation tuaj yeem txhim kho lub diffusion ntawm qhov micro-qhov nyob rau hauv cov khoom kua huab hwm coj hloov txheej txheem, yog li mus ntxiv dag zog rau eddy diffusion thiab accelerate tus txheej txheem extraction. Lub ultrasonic zaus ntau zog, lub extraction lub sij hawm yog lub caij nyoog, thiab cov nyhuv polymerization uas ua los ntawm ultrasonic teb ua rau cov kub uas txias extraction. Lub turbulence nyhuv, perturbation nyhuv, interfacial nyhuv thiab cov nyhuv clustering muaj feem xyuam rau zaus, fais fab thiab kub ntawm lub teb ultrasonic. Nyob rau hauv tus txheej txheem ntawm extraction ntawm ntuj khoom, xovtooj ntawm phab ntsa-tawg, ntsuas ceev thiab lub diffusion ntawm lub solute yog txuam nrog ultrasonic zog ib cheeb tsam twg, thiab yuav cuam tshuam rau cov extraction efficiency thiab rov ua hauj lwm, yog li feem ntau xaiv tsawg zaus high fais fab ultrasound .

Txawm hais tias ultrasonic extraction nyhuv yog zoo heev hauv me me qauv npaj rau hauv kev kuaj thiab tau lug siv, tshwj xeeb tshaj yog nyob rau hauv kev ntsuam xyuas ntawm cov qauv ua, tus yam ntxwv ntawm nws sai, npaum tau lug, tab sis qhov uas thiab qhov siv ntawm lub ultrasonic teb lub sij hawm txwv mus rau cov nyiaj ntawm cov khoom siv, vim tsis muaj txiaj ntsim zoo ntawm engineering amplification txoj kev thiab txwv nws daim ntawv thov nyob rau hauv loj qhuav.
