Txoj Cai Ua Haujlwm Thiab Qhov Zoo Ntawm Ultrasonic Extraction Technology

Ultrasonic extraction thev naus laus zis yog cov txheej txheem nyiam rau kev cais cov tshuaj bioactive los ntawm cov nroj tsuag. Ultrasound hais txog cov tshuab suab tsis muaj zaus tshaj 20 kHz tab sis tsawg dua 10 MHz. Ultrasonic extraction feem ntau siv ntau zaus me me (16 kHz - 100 kHz), raws li ntau zaus tuaj yeem ua rau lub zog ntau dhau, uas tuaj yeem ua rau kev puas tsuaj ntawm cov khoom siv hauv cov nroj tsuag.

Sonication enables tiav extraction, uas ua rau siab extraction yields nyob rau hauv luv luv extraction lub sij hawm. Raws li txoj kev rho tawm tau zoo, ultrasonic extraction txuag tau ob qho tib si nqi thiab lub sij hawm thaum yielding siab - zoo extracts rau siv nyob rau hauv cov zaub mov, tshuaj, thiab tshuaj.

01 Nws ua haujlwm li cas

Ultrasonic extraction yog raws li lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm ultrasonic cavitation thiab yog ib tug purely mechanical kho. Zoo ib yam li siab shear mixers, sonotrodes tsim txhua yam shear rog tsuas yog nyob rau hauv cov txheej txheem nruab nrab. Ultrasonic extraction nws tus kheej yog ib tug uas tsis yog - thermal, tshuaj - dawb extraction txheej txheem.

Ultrasonic cavitation yog sonic lossis ultrasonic cavitation uas tshwm sim ntawm lub zog siab, raws li kev rov ua kom siab thiab qis qis. Qhov hloov pauv siab thiab qis qis ntawm sonication 20, 000 zaug ib ob tsim cov shear quab yuam thiab cov dav hlau ua kua. Qhov kev ntxhov siab no kov yeej cov kev xaiv ntawm daim nyias nyias, perforates thiab cuam tshuam cov phab ntsa ntawm tes, thiab ua rau siab - kev thauj mus los ntawm cov cell sab hauv thiab cov kuab tshuaj ib puag ncig. Nrog ultrasonic extraction, ntau yields thiab luv luv extraction sij hawm yuav ua tau tiav. Txij li thaum ultrasonic extraction yog ib qho txheej txheem rov ua dua, cov txiaj ntsig rho tawm tuaj yeem rov ua dua rau cov txheej txheem rho tawm zoo.

Ultrasonic cavitation tuaj yeem ua rau hauv cheeb tsam huab cua xws li kev sib txawv siab heev thiab siab shear rog. Thaum cavitation npuas tawg mus rau saum npoo ntawm cov khoom khib nyiab (xws li hais, cog hlwb, cov ntaub so ntswg, thiab lwm yam), micro - dav hlau thiab inter - particle collisions tuaj yeem tsim cov teebmeem xws li particle rupture, sonoporation (perforation ntawm cell phab ntsa thiab daim nyias nyias), thiab cellularity. . Tsis tas li ntawd, qhov bursting ntawm cavitation npuas nyob rau hauv cov kua xov xwm tsim turbulence thiab agitation, uas pab txhawb kev loj hlob ntawm lub sab hauv ntawm lub cell thiab ib puag ncig hnyav. Ultrasound hluav taws xob yog ib txoj hauv kev zoo los txhim kho cov txheej txheem hloov loj, raws li ultrasound induces cavitation thiab nws cov txheej txheem cuam tshuam, xws li micromotion induced los ntawm cov kua dav hlau, compression thiab decompression nyob rau hauv cov ntaub ntawv, thiab tom qab cell phab ntsa cuam tshuam.

02 Qhov zoo

Ultrasonic extraction tuaj yeem txo cov kuab tshuaj thiab ua kom cov kuab tshuaj ntau dua. Qhov no txhais tau hais tias ultrasonic extraction txhim kho extraction yields thiab ua rau noj qab haus huv extracts. Qhov no yog vim nws cov yam ntxwv ntawm kev khiav hauj lwm ntawm qhov kub thiab txias, uas tuaj yeem tsis tsuas yog txo cov cua sov los ntawm qhov kub thiab txias, tab sis kuj tsis txhob vaporization ntawm cov khoom vim cov ntsiab lus boiling tsawg thiab tswj cov khoom siv roj ntsha. Ultrasonic extraction yog ib daim ntawv thov yooj yim, nyab xeeb thiab meej tswj tau. Raws li ib tug tsis yog - thermal extraction txoj kev, sonication yuav ua tau nyob rau hauv qis kub, yog li zam lub degradation ntawm thermally rhiab heev, thermally unstable tshuaj. Ultrasonic extraction kuj muaj peev xwm txo tau lub sij hawm ntau lawm, raws li kev mus ncig ultrasound cuam tshuam cov phab ntsa ntawm tes, yog li txo lub sij hawm hloov ntawm cov khoom xyaw nquag ntawm cov khoom cog rau cov kuab tshuaj.

03 Cov nyhuv ntawm ultrasonic rho tawm

Ultrasonic Cell cuam tshuam thiab nce loj Hloov Ultrasound tuaj yeem pab cov txheej txheem rho tawm los ntawm kev cuam tshuam ntawm tes thiab txhim kho huab hwm coj hloov pauv hauv cov ciam teb ib puag ncig cov khoom matrix. Raws li perforation ntawm cov phab ntsa ntawm tes thiab daim nyias nyias, ultrasound tuaj yeem txhim kho permeability ntawm phab ntsa ntawm tes thiab daim nyias nyias, feem ntau yog theem nrab ua ntej cov hlwb puas tag los ntawm ultrasound.

Mechanical teebmeem ntawm ultrasound - induced cavitation, xws li kub thiab siab sib txawv, poob siab tsis, shear rog, kua jets, thiab microfluidics, txhim khu cov kuab tshuaj nkag mus rau hauv lub sab hauv ntawm lub hlwb thiab txhim kho loj hloov ntawm cov hlwb thiab cov kuab tshuaj, tso cai rau cov ntaub ntawv intercellular yog pauv mus rau qhov hnyav.

04 Cov ntsiab lus

Ultrasonic extraction technology siv cov cavitation uas ua los ntawm ultrasonic tsis los extract cov khoom xyaw nquag ntawm cov nroj tsuag. Piv nrog rau cov qauv kev rho tawm, ultrasound - pab extraction txoj kev ua kom zoo nkauj dua vim lawv ntau yam zoo, xws li kev siv hluav taws xob tsawg, lub sij hawm rho tawm luv luv, tsawg dua kev puas tsuaj ntawm cov khoom sib txuas, thiab cov txiaj ntsig siab extraction.
