Taw qhia rau daim ntawv thov ntawm ultrasonic homogenization cov khoom siv hauv kev lag luam khoom noj khoom haus
Tus nqi hluav taws xob qauv ntawm ultrasonic homogenizing cov cuab yeej muaj qhov zoo ntawm cov qauv yooj yim, siv yooj yim, huv si thiab huv si, thiab kev sib xyaw ua ke. Nws txais yuav ultrasonic cov lej hluav taws xob tswj lub zog hluav taws xob, tswj hluav taws xob tag nrho digital, thiab muaj zog tiv thaiv kev cuam tshuam muaj peev xwm. Cov khoom siv ultrasonic muaj qhov tsim kom ruaj khov, lub sijhawm ua haujlwm ntev txuas, thiab lub cheeb tsam hluav taws xob yog 2,5 npaug loj dua li cov cuab yeej ntawm lub taub hau tsoos.
Ntawm nimno, ultrasonic homogenization khoom siv mas siv cov khoom noj siv mis. Hauv cov mis nyuj uas ntuj tsim, cov roj lub ntsej muag tsis sib xws, txij li 1 txog 10 μm, feem ntau 2 txog 5 μm [1]. Cov roj globules ntab rau cov mis saum npoo vim muaj ntab los ua ib txheej txheej ntawm qab zib, uas ua rau cov mis ua kom cov kua tsim muaj Delamination tshwm sim. Qhov muaj ntawm cov rog rog rog no cuam tshuam rau cov tsos thiab saj ntawm cov mis thiab cov khoom noj siv mis.
Yog tias cov mis yog homogenized, txoj kab uas hla ntawm cov rog rog tuaj yeem tswj tau ntawm thaj tsam li 2μm. Lub sijhawm no, thaj chaw thaj tsam ntawm cov mis nyuj muaj roj ntau zuj zus thiab lub cev ntog tsawg zuj zus, kom thiaj li zam dhau stratification thiab ua tiav cov nyhuv ntawm homogenization. Lub txiaj ntsig tshwj xeeb ntawm homogenization txhim kho cov khoom muaj txiaj ntsig zoo ntawm kev saib pom thiab saj. Yog li, homogenization yog ib qho tseem ceeb ntawm cov txheej txheem pretreatment ntawm cov khoom siv mis.
Tom qab cov nqaij nyoos homogenized, qhov zoo li, saj, cov zaub mov muaj txiaj ntsig thiab lwm yam zoo ntawm cov khoom noj siv mis yuav zoo dua, yog li kev kho homogenization yog qhov tseem ceeb tshaj plaws hauv kev tsim ua ntej ntawm cov khoom noj siv mis. Ultrasound muaj cov homogeneous zoo rau cov khoom vim cavitation thiab lwm yam kev cuam tshuam ntawm lub cev. Ntau cov kev tshawb fawb tau tshaj tawm cov homogenization nyhuv ntawm ultrasound ntawm mis nyuj.
Cov khoom siv mis nyuj muaj ntau dua thiab nrov dua nrog cov neeg vim lawv cov zaub mov muaj txiaj ntsig zoo thiab tsw qab. Cov kua mis nyeem qaub tsis tuaj yeem tsuas yog muab cov calcium, phosphorus, magnesium, vitamin A, riboflavin xwb, tabsis kuj tseem muaj cov micro-ecological probiotics uas muaj txiaj ntsig zoo rau tib neeg lub cev. Hauv 30 xyoo dhau los, kev lag luam kua mis nyeem qaub tau loj hlob sai. Txhawm rau kom ceev txoj kev loj hlob sai, kev tsim kho tshiab yuav tsum tau tsim yog siv tshuab ua kua mis nyeem qaub, ntim khoom, saj thiab ntxig.
Cov kev tshawb fawb pom tau tias kev tsim cov mis nyuj ultrasound tuaj yeem ua rau kom cov vis dis aus kua mis nyeem qaub thiab txhim kho cov khoom noj muaj mis ua kom zoo li qub. Xws li cov kua qaub tsim ruaj khov, nws yooj yim los tswj; ntawm cov ntsuas xws li aroma, tsos, xim, thiab saj, ultrasonic kua mis nyeem qaub homogenized ua tau zoo nyob rau hauv cov lus ntawm aroma thiab tsos; nws tuaj yeem nce tus nqi hloov kho ntawm lactose, thiab rau cov neeg uas tsis haum lactose Nws yog qhov tseem ceeb; lub sij hawm fermentation txo qis; dej tuav muaj peev xwm thiab viscosity ntawm yogurt yog nce, thiab syneresis yog txo.
