Phacoemulsification ua si nws txoj haujlwm tshwj xeeb hauv ntau daim teb
Phacoemulsification yog hais txog cov txheej txheem sib xyaw ob (lossis ntau dua ob qho) cov kev daws teeb meem tsis sib xws los tsim kev tawg nyob rau hauv qhov kev ua ntawm lub zog ultrasonic, nyob rau hauv uas ib qho kua tseem tau faib rau lwm cov kua los ua emulsion. Piv nrog dav dav emulsification thev naus laus zis thiab khoom siv (xws li kiv cua, colloid zeb, homogenizer, thiab lwm yam), ultrasonic emulsification muaj cov yam ntxwv ntawm emulsification siab zoo, emulsification ruaj khov, ruaj khov emulsified khoom thiab qis zog yuav tsum tau.
Phacoemulsification tau thov nyob rau hauv ntau daim teb, thiab nws ua lub luag haujlwm tshwj xeeb hauv txhua daim teb.
Muaj ntau ntau cov ntawv lag luam phacoemulsification. Ultrasonic emulsification yog ib qho ntawm cov tshuab ntxov tshaj plaws uas siv rau hauv kev ua khoom noj. Piv txwv li, dej qab zib, ketchup, mayonnaise, jam, khoom noj mis nyuj, khoom noj me nyuam, chocolate, qab ntsev roj, dej qab zib thiab lwm yam khoom siv sib xyaw ua ke hauv kev lag luam khoom noj tau raug sim thiab coj los siv hauv tsev thiab txawv teb chaws, thiab txhim kho cov nyhuv cov khoom lag luam zoo thiab ntau lawm, thiab aqueous carotene emulsification tau tiav kev sim thiab siv ntau lawm.
Cov txiv tsawb tev hmoov ua ntej ua ntej los ntawm kev hloov kho lub cev ntawm ultrasonic dispersion sib xyaw nrog kev kub siab ua noj, thiab tom qab ntawd cov txiv tsawb tev hmoov yog enzymatically hydrolyzed nrog amylase. Ib qho kev sim tsuas tau siv los kawm txog cov txiaj ntsig ntawm qhov kev txuam no ua ntej ntawm kev rho tawm ntawm cov tshuaj soluble fiber ntau hauv cov txiv tsawb tev thiab cov yam ntxwv ntawm lub cev ntawm txiv tsawb tev insoluble fiber ntau kev noj haus. Cov txiaj ntsig pom tau tias ultrasonic dispersion ua ke nrog kev kub siab ua noj yog piv rau cov kev kho mob yooj yim yam tsis muaj kev tiv thaiv ua ntej. Cov insoluble noj haus fiber ntau tau los ntawm kev kho mob enzyme nce cov dej tuav tau los ntawm 5.05g / g, dej sib xyaw muaj peev xwm los ntawm 4.66g / g, roj tuav muaj peev xwm los ntawm 4.60g / g, thiab lub peev xwm o tau los ntawm 0.4mL / g.
Hauv kev lag luam kws tshuaj thiab kev lag luam niaj hnub tsim nyog, phacoemulsification feem ntau siv hauv kev tsim cov tshuaj ntau yam emulsion, xws li tshuaj emulsion, tshuaj pleev ib ce, thiab khau polish. Ultrasonic emulsification txoj kev kuj tseem siv tau los ua emulsified cov khoom sib txuas ntawm cov roj (roj av, roj av, thiab lwm yam) thiab dej lossis pulverized thee kom cov nqi sib txuas ntxiv rau ib pawg roj.
