Ultrasonic extraction yog ib lub tshuab uas siv cov nyhuv cavitation ntawm ultrasonic tsis. Ultrasonic nthwv dej vibrate 20000 zaug ib ob, ua rau cov microbubbles yaj nyob rau hauv nruab nrab, tsim ib tug resonant kab noj hniav, thiab ces tam sim ntawd kaw los tsim ib tug haib micro cuam tshuam. Los ntawm kev ua kom lub zog ceev ntawm nruab nrab molecules thiab ua kom cov permeability ntawm nruab nrab, cov khoom zoo ntawm cov khoom raug muab rho tawm. Nyob rau tib lub sijhawm, lub dav hlau micro tsim los ntawm muaj zog ultrasonic kev co tuaj yeem ncaj qha nkag mus rau phab ntsa ntawm tes ntawm cov nroj tsuag. Nyob rau hauv qhov kev txiav txim ntawm lub zog ultrasonic muaj zog, cov nroj tsuag cov hlwb sib tsoo nrog ib leeg, txhawb kev tawg ntawm cov khoom xyaw zoo ntawm phab ntsa ntawm tes.
Cov khoom tshwj xeeb ntawm lub cev ntawm ultrasound tuaj yeem txhawb txoj kev tawg lossis deformation ntawm cov ntaub so ntswg ntawm cov nroj tsuag, ua kom cov extraction ntawm cov khoom xyaw zoo hauv tshuaj ntsuab ntau dua thiab txhim kho tus nqi rho tawm piv rau cov txheej txheem ib txwm muaj. Ultrasound enhanced extraction ntawm tshuaj ntsuab feem ntau yuav siv sij hawm 24-40 feeb kom tau qhov zoo tshaj plaws extraction tus nqi. Lub sij hawm extraction yog heev txo los ntawm
ntau tshaj 2/3 piv rau cov txheej txheem ib txwm muaj, thiab kev ua haujlwm ntawm cov khoom siv raw rau cov khoom siv tshuaj yog loj. Qhov zoo tshaj plaws kub rau ultrasonic extraction ntawm tshuaj ntsuab yog nyob nruab nrab ntawm 40-60 ℃, uas muaj ib tug tiv thaiv nyhuv ntawm active cov khoom xyaw nyob rau hauv cov ntaub ntawv tshuaj uas tsis ruaj tsis khov, yooj yim hydrolyzed los yog oxidized thaum raug tshav kub, thaum zoo heev txuag zog noj;
