Ntsiab Cai Thiab Cov Cwj Pwm Ntawm Ultrasonic Extraction

Ultrasonic extraction siv cov teeb meem txhua yam, cavitation teebmeem thiab thermal teebmeem ntawm ultrasonic tsis mus txheeb cov roj ntsha yam khoom ua tau los ntawm kev ua kom tshaj tawm ntawm cov khoom nruab nrab thiab nce lub zog ntawm qhov nruab nrab.

Mechanical nyhuv

Qhov hais tawm ntawm ultrasonic tsis nyob hauv nruab nrab yuav ua rau nruab nrab hais mus rau hauv lawv qhov chaw qhov chaw tawm, qhov no pab tau qhov diffusion thiab tawm ntawm qhov nruab nrab, uas yog cov neeg ua haujlwm ntawm cov ultrasonic tsis. Ultrasonic tsis ua kom muaj ib hom hluav taws xob hauv cov txheej txheem ntawm kev tawm tswv yim, uas propagates raws cov kev taw qhia ntawm lub suab tsis, uas muaj lub zog ua rau cov khoom siv, uas tuaj yeem deform cov nqaij thiab cov kab npauj ntawm cov nroj tsuag. Nyob rau tib lub sijhawm, nws tuaj yeem muab qhov nruab nrab thiab kev ncua kev sib tw ntau. Thiab tus tshaj tawm ntawm lub nruab nrab molecules yog sai dua qhov tshaj tawm ntawm cov raug rho tawm haujlwm molecules. Li no, txhuam yog generated ntawm ob, uas tau depolymerize cov biomolecules, kom lub zog yam ntawm cov phab ntsa ntawm tes dissolve nyob rau hauv qhov hnyav sai.

Cavitation nyhuv

Feem ntau, qee qhov microbubbles muaj ntau dua los yog tsawg dua hauv nruab nrab. Cov npuas voos nyob rau hauv qhov kev txiav txim ntawm ultrasonic tsis. Thaum lub suab siab nce mus txog ib qho nqi, cov npuas yuav nce ntxiv vim hais tias qhov kev tswjfwm sib txuas lus (rectieddiffvsion), tsim cov kab noj hniav. Tom qab ntawd dheev kaw, qhov no yog cov nyhuv cavitation ntawm ultrasound. Thaum lub npuas raug kaw lawm, nws ua rau lub siab ntawm ob peb txhiab atmospheres ncig nws, tsim ib lub micro-shock, uas tuaj yeem ua rau ntawm phab ntsa cog thiab tag nrho cov kabmob ua rau tawg, thiab tag nrho txoj kev tawg yog tiav hauv ib qho instant, uas yog rau qhov dissolution ntawm lub active khoom sib ua.

Thermal cov nyhuv

Zoo li lwm yam tsis muaj lub cev, qhov kev tawm tswv yim ntawm ultrasonic tsis nyob hauv nruab nrab kuj yog lub zog tawm thiab qhov kev tawm dag zog. Ntawd yog, thaum lub sij hawm cov lus dag ntawm ultrasonic tsis, lub zog acoustic yog tsis tu ncua absorbed los ntawm cov khoom ntawm lub nruab nrab, thiab lub zog absorbed los ntawm lub nruab nrab yog tag nrho los yog loj. Ib nrab hloov mus rau thermal lub zog ua rau nce nyob rau hauv qhov kub ntawm nruab nrab nws tus kheej thiab cov ntaub so ntswg, uas nce lub dissolution rate ntawm lub active khoom sib xyaw ntawm cov tshuaj. Txij li thaum nce hauv qhov kub thiab txias ntawm cov tshuaj siv los ntawm qhov nqus ntawm lub zog acoustic instantaneous, qhov kev ua txheeb raws roj ntsha ntawm qhov muab rho tawm tau khaws cia tas li.

Tsis tas li ntawd, ultrasound kuj tuaj yeem ua tau ntau yam ntxiv, xws li emulsification, diffusion, crushing, tshuaj muaj teebmeem, lwm yam zoo li Cov teebmeem no kuj txhawb kev sib txawv ntawm cov khoom xyaw dhia hauv cov nroj tsuag, txhawb qhov nkag ntawm cov khoom xyaw rau hauv nruab nrab, thiab tag nrho sib tov nruab nrab kom leeb Cov txheej txheem extraction yog nqa tawm thiab qhov kev rho tawm ntawm cov khoom sib txuam ntawm cov tshuaj no zoo tuaj.

Cov yam ntxwv ntawm ultrasonic extraction

Ultrasonic extraction tsis tau cua sov, uas tiv thaiv cov teebmeem ntawm cov tsoos suav tshuaj tshuaj kub thiab kub-ntev rau ntawm cov khoom xyaw dhia, thiab tsim rau cov extraction ntawm cov tshav kub-sensitive. Tib lub sijhawm, nws txuag lub zog vim nws tsis tas yuav muaj cua sov.

Ultrasonic extraction pab txoj kev extraction tus nqi ntawm cov khoom xyaw dhia ntawm cov tshuaj, txuag cov ntaub ntawv raw, facilitates cov kev siv tas nrho cov tshuaj suav tshuaj, thiab pab txhim kho cov nyiaj txiag.

Qhov hnyav yog siv me me, txuag kuab.

Ultrasonic extraction yog lub cev nqaij daim tawv uas tsis muaj tshuaj lom neeg cov tshuaj tshwm sim thaum lub sij hawm tag nrho kev leaching txheej txheem thiab tsis cuam tshuam rau kev ua haujlwm ntawm feem ntau ntawm cov khoom xyaw dhia ntawm cov tshuaj.

Cov extract muaj cov ntsiab lus ntawm cov khoom xyaw thiab yog ib qho kev zoo dua rau kom huv.
