Cov txheej txheem ntawm cov roj emulsificate cuam tshuam nrog roj thiab dej rau hauv lub tshuab ua ntej hauv ib qho kev sib piv tsis muaj kev sib ntxiv. Los ntawm ultrasonic emulsification, lub immiscible dej thiab roj yauv nrawm hloov lub cev, ua rau muaj cov kua mis dawb hu ua "dej hauv cov roj". Tom qab kev kho lub cev nqaij daim tawv xws li ultrasonic kua xuav, muaj zog magnetization, thiab venuri, ib hom kua nrog "dej hauv cov roj" thiab muaj cov pa roj "thiab cov pa roj oxygen thiab cov pa. Ntau tshaj 90% ntawm emulsified hais tawm yog qis dua 5 μ m, qhia tau kev ruaj khov zoo ntawm cov roj emulsified hnyav. Nws tuaj yeem khaws cia ntawm chav tsev kub rau lub sijhawm ntev yam tsis tau tawg cov emulsion, thiab tuaj yeem ua kom sov li 80 ℃ rau ntau tshaj 3 lub lis piam.
Txhim kho emulsification
Ultrasound yog ib txoj kev ua tau zoo los txo cov particle loj li cas ntawm dispersion thiab pleev. Cov khoom siv ultrasonic emulsification tuaj yeem tau txais lotion nrog rau cov me me me me (tsuas yog 0.2 - 2 μ m) thiab nqaim dopplet loj faib (0.1 - 10 -2 m). Cov concentration ntawm cov tshuaj pleev tau nce ntxiv ntawm 30% mus rau 70% los ntawm kev siv emulsifiers.
Txhim kho qhov ruaj ntseg ntawm cov tshuaj pleev
Txhawm rau kom ruaj khov cov tee dej ntawm cov theem dispersed tshiab los tiv thaiv cov hluav taws xob, emulsifiers thiab stabilizers tau ntxiv rau cov tshuaj pleev rau hauv cov txheej txheem ib txwm muaj. Cov tshuaj pleev tau ruaj khov tuaj yeem muab tau los ntawm ultrasonic emulsification nrog me me lossis tsis muaj emulsifier.
Ntau yam kev siv
Ultrasonic emulsification tau raug siv rau hauv ntau thaj teb. Xws li cov dej qab zib, lws suav sauce, mayonnaise, chocolate, zaub xam lav, roj thiab lwm yam khoom noj uas siv hauv kev lag luam khoom noj.
