1. Lub hauv paus ntsiab lus ntawm homogenization thiab emulsification
Hauv qhov chaw ua haujlwm, cov txheej txheem roj-dej emulsification feem ntau ua tiav nrog kev siv cov emulsifier los tsim cov kev xav tau dispersion thiab homogeneity thaum muaj ob cov kua dej tsis sib haum lossis cov khoom ua kua sib xyaw. Nws yog tsis yooj yim sua rau cov dej nyob rau hauv cov roj los yog roj nyob rau hauv cov ntaub ntawv ntawm cov roj-dej ob-theem nruab nrab nyob rau hauv stably. Txhawm rau nce cov kab ke ntawm cov kab nro, cov qauv tsim nyog emulsifiers yuav tsum muaj. Txhawm rau rhuav tshem qhov nruab nrab mus rau hauv cov khoom me me tib lub sijhawm, yuav tsum muaj qhov muaj zog txiav dispersion. Tom qab ntawd, ib qho kev ruaj khov thiab tsis sib haum xeeb yog tsim los tsim cov nyhuv emulsification zoo.
Kev siv cov tshuab emulsifying tam sim no tsis yog rau emulsifying xwb. Lub tshuab emulsion muaj cov nyhuv shearing muaj zog uas tuaj yeem rhuav tshem cov hmoov nplej hauv qab kev cuam tshuam, ua kom zoo rau cov khoom me me, thiab tom qab ntawd muab cov khoom sib xyaw ua ke rau hauv cov kua los ua ib qho kev sib piv tsis tu ncua. Lub kaw lus tuaj yeem suav tau tias yog homogeneous thaum cov khoom zoo nkauj mus txog qhov micron lossis txawm tias qib nanoscale.
Kev kub siab homogenization tuaj yeem txo cov ntaub ntawv rau cov khoom me me thiab emulsify thiab homogenize ib txhij los tsim cov emulsion ruaj khov. Yog li ntawd, cov emulsifier tuaj yeem raug hu ua homogenization emulsifier.
2. Homogenizer Txoj Cai
Shear quab yuam thiab siab yog homogenizer tus thawj tsav tsheb quab yuam. Cov nyhuv laminar ntws yog tsim thaum lub sij hawm homogenization txheej txheem, uas ua rau lub dispersed theem hais los yog tee dej yuav sheared, stretched, thiab shattered; Nyob rau hauv qhov cuam tshuam ntawm cov nyhuv turbulence, hais los yog cov tee dej yuav random deform nyob rau hauv teb rau kev hloov siab; nyob rau hauv kev cuam tshuam ntawm cov nyhuv cavitation, cov npuas me me yuav tawg sai sai thaum muaj kev kub ntxhov, tso tawm lub zog thiab ua rau hauv zos hydraulic shock thiab kev co. Cov ntaub ntawv sib npaug sib npaug vim yog cov haujlwm ua ke no.
3. High Shear Emulsifier Txoj Cai
Lub rotor thiab stator ua rau lub taub hau shear. Ua ke, rotor thiab stator mesh. Muaj ntau txheej ntawm iav rings nyob rau hauv txhua theem ntawm stator thiab rotor. Ib qho chaw muaj zog tsis zoo yog tsim thaum lub rotor tig nrawm los muab lub zog centrifugal muaj zog. Nyob rau hauv lub stator thiab rotor sib txawv, cov khoom yog kos mus rau hauv lub chav ua hauj lwm qhov twg nws yog raug rau ntau yam quab yuam xws li shearing, centrifugal extrusion, cuam tshuam tsim kua muag, turbulence, thiab lwm yam, uas ua rau lub nro ntawm splitting droplets. Lub siab nce ib zaug ntxiv tom qab cov kua tawm ntawm lub qhov stator, ua rau cov nyhuv cavitation. Kev sib hloov ceev ceev ntawm homogenizing lub taub hau txiav, tawg, thiab cuam tshuam cov ntaub ntawv.
Thaum ua cov ntaub ntawv granular nrog ntau fibers lossis cov ntaub ntawv nyuaj, lub tshuab shear siab emulsification yog qhov tsim nyog dua. Homogenization, sterilization, thiab kev sib tov tuaj yeem ua tiav ib txhij. Nrog kev pab los ntawm high-shear emulsification technology, tsim los ntawm Liu Junmei thiab lwm tus neeg, taum protein tau txo qis hauv protein particle loj thiab raug rau hydrophobic pab pawg, uas txhawb kev tsim cov gel tes hauj lwm thiab txhim kho cov taum protein cais gel lub peev xwm los tuav dej. . Los ntawm kev siv cov tshuab hluav taws xob siab ceev shear emulsification rau pob kws gluten hmoov, Guo Weijing li al. hloov cov khoom ntawm lub cev ntawm cov hmoov protein. Cov txheej txheem no tuaj yeem txo qhov loj me me, txhim kho rheology thiab solubility, txhim kho cov hmoov txhuv nplej siab degradation thiab protein hydrolysis degree, thiab ua tiav inhibit stratification ntawm txiv hmab txiv ntoo thiab zaub kua txiv.High shear emulsification tshuab yog dav siv nyob rau hauv cov khoom uas muaj viscosity siab thiab siab emulsification yuav tsum, xws li jam, txiv hmab txiv ntoo tshuaj yej, thiab lwm yam.
