Khoom noj khoom haus kev lag luam membrane filtration cais concentration technology

Kev lag luam khoom noj siv mis siv tshuab sib cais los ntawm kev sib cais thiab tshuaj xyuas ntau yam khoom siv hauv cov khoom siv mis, mloog cov mis nyuj, ua kom tsis muaj menyuam, rov ua dua ntau yam ntawm cov whey, thiab kho cov dej khib nyiab.Kev siv cov txheej txheem sib cais membrane hauv kev lag luam khoom noj siv mis tuaj yeem ua kom yooj yim cov txheej txheem, txo kev siv hluav taws xob, txo cov dej khib nyiab, txhim kho cov khoom siv mis nyuj zoo, thiab txhim kho kev siv cov khoom noj siv mis.Niaj hnub no, tus editor ntawm Bona Bio yuav qhia txog daim ntawv thov ntawm daim nyias nyias nyias tshuab hauv cov ntsiab lus ntawm cov mis nyuj thiab cov khoom siv mis nyuj.

Mis thiab cov khoom siv mis nyuj membrane sib cais cov cuab yeej siv tshuab

1. Kev khiav dej num ntawm ultrafiltration concentrated skim mis nyuj thiab whey yog raws li nram no:
skim mis los yog whey - pretreatment - ultrafiltration - desalination - evaporation - tsuag ziab - cov khoom tiav - ntim

Cov txheej txheem ib txwm muaj ntawm cheese ntau lawm yog ntxiv cov pib thiab rennet rau skim mis nyuj ua ntej sib tov thiab coagulation.Thaum lub sijhawm txheej txheem no, 25% ntawm cov whey protein yuav raug precipitated los ntawm curd thiab tawm mus rau hauv whey thiab poob.Nrog rau ultrafiltration kom mloog zoo skim mis, feem ntau ntawm cov lactose tuaj yeem raug tshem tawm los ntawm daim nyias nyias, thiab feem ntau ntawm cov whey protein yog khaws cia rau hauv cov kua mis concentrated los ntawm daim nyias nyias, yog li txhim kho cov txiaj ntsig thiab zoo ntawm cheese.Cov txheej txheem hauv paus yog raws li nram no:
Skim mis nyuj - Pretreatment - Ultrafiltration - Concentrate - Ntxiv pib - Cheese ua - Cheese

Rov qab osmosis concentration tuaj yeem tshem tawm ntau dua 60% ntawm cov dej thiab nce cov ntsiab lus ntawm cov mis nyuj los ntawm 8% mus rau 22%, thaum cov khoom xa tawm tsuas yog 0.15% ~ 0.2%.skimmed mis nyuj concentration txais ultrafiltration ntawm 30 ~ 50 ℃ kom concentrate skimmed mis nyuj rau 3 ~ 4 zaug ntawm cov khoom.Tom qab lactose thiab ntsev raug tshem tawm los ntawm dilution pom, skimmed mis nyuj nrog cov ntsiab lus protein txog li 80% tuaj yeem tau txais thiab tom qab ntawd qhuav, uas tuaj yeem txuag tau ntau lub zog.

2. Whey protein Rov qab thiab whey desalination
Siv ultrafiltration thiab thim rov qab osmosis thev naus laus zis, lactose thiab tshauv tuaj yeem raug tshem tawm ntawm qhov permeate ntawm daim nyias nyias thaum tsom rau whey protein, uas nthuav dav ntau yam ntawm whey.Tom qab kev taw qhia ntawm ultrafiltration thiab thim rov qab osmosis, qhov zoo ntawm whey protein tau zoo dua.

Thaum nanofiltration yog siv los kho whey, monovalent hlau ions thiab chloride ions tuaj yeem dhau mus, thaum divalent ions thiab lwm yam khoom feem ntau cuam tshuam rau qee yam, thiab tag nrho cov protein raug cuam tshuam.Lub intercepted whey tuaj yeem raug rau circulating nanofiltration kom txog thaum cov ntsev cov ntsiab lus hauv cov whey txo mus rau qib uas yuav tsum tau ua.

Shandong Bona Group yog cov chaw tsim khoom ntawm cov khoom siv lim membrane, nrog ntau xyoo ntawm kev paub hauv kev tsim khoom thiab kev xyaum ua haujlwm.Tsom ntsoov rau kev daws qhov teeb meem ntawm kev pom thiab concentration hauv cov txheej txheem ntawm cov khoom siv roj ntsha fermentation / dej cawv / suav tshuaj extraction / tsiaj txhu thiab cov nroj tsuag extraction.Yog tias koj muaj lus nug txog kev lim dej, thov koj xav tiv tauj peb, thiab peb yuav muaj cov kws tshaj lij los pab koj.Shandong Bona Group yuav muab kev pabcuam zoo tshaj plaws!
