Ngokuvamile sebenzisa isistimu yokuhlunga ulwelwesi lwe-ceramic ukuze uhlukanise amaprotheni e-Concentrated milk milk (MPC) nama-isolated milk proteins (MPI) nobisi olusha lwe-skim.hey acebile nge-casein ne-whey protein, ahlanganisa i-calcium ecebile nokuzinza okuhle kokushisa kanye nokuzwakala komlomo okuqabulayo.
Amaphrotheni obisi agxilile asetshenziswa kakhulu futhi alungele imikhiqizo kashizi, imikhiqizo yokwenziwa, iziphuzo zobisi, ukondliwa kwezingane, imikhiqizo yokudla okunempilo, imikhiqizo yokulawula isisindo, izithasiselo zokudla eziyimpuphu kanye nemikhiqizo yokudla kwezemidlalo.
Ngokuvamile, ukugxila kwamaprotheni obisi kuhlinzeka ngomthombo ogxilile wamaprotheni ezinzwa nezisebenzayo ohlelweni lokugcina lokufaka isicelo ukuze kuhlangatshezwane nenani lokudla okunempilo.Amaprotheni obisi olujiyile asebenza njengenye indlela ye-whole milk powder (WMP), skim milk powder (SMP) nezinye izimpusha zobisi, ehlinzeka ngeprotheyini efanayo, noma njenge-non-fat milk solid (MSNF).Uma kuqhathaniswa nobisi olujwayelekile noma i-skim milk powder, amaprotheni obisi agxilile anamaprotheni amaningi, izici eziphansi ze-lactose.
Inqubo evamile yokuvala inzalo ekushiseni okuphezulu kakhulu izocekela phansi imisoco eminingi esebenzayo obisini kodwa ubuchwepheshe bokuhlunga ulwelwesi lwe-ceramic obusezingeni eliphansi lokushisa buchitha ngokuphelele ukuvala ubisi okujwayelekile kwezinga lokushisa eliphezulu.Inqubo yokuhlunga ubisi kanye nokucaciswa ukwenza ubisi olusha lwemvelo lube uketshezi ngobuchwepheshe be-ceramic membrane yobisi futhi kugwenywe ukushisa kweprotheni.
Ukususwa Kwamagciwane
Njengokudla okuningi, ubisi nezinto eziphuma kulo kunikeza indawo efanelekile yokubola kwamagciwane.Ngakho-ke, ukwelashwa kwangaphambili kanye nezinga lokushisa, imingcele yesikhathi kufanele ikhethwe ukulawula ukukhula kwama-microorganisms.Ukwelashwa kokushisa kanye nokuvala inzalo nge-centrifugal izindlela zendabuko zokunciphisa inani eliphelele lamagciwane obisini nemikhiqizo yobisi, kodwa lezi zindlela zinezinzuzo zazo kanye nokubi.Izindlela zendabuko zokususa amabhaktheriya obisini zinezinyathelo eziningi kanye nezindleko eziphakeme, ukuphila okufushane, ukungcoliswa kwemvelo, ukuhlanza okungalungile.Kodwa-ke, i-ceramic membrane filtration yobisi ingaxazulula lezi zinkinga.
Ubuchwepheshe bokuhlukanisa ama-membrane busetshenziselwa ukuqeda amagciwane obisini, okusekelwe eqinisweni lokuthi ulwelwesi lunamazinga ahlukene okugcina impahla ezingxenyeni ezihlukahlukene zobisi, okuhlanganisa amagciwane kanye nezinhlamvu.Amagciwane angenza izinga lokwenqatshwa libe ngaphezu kuka-99%, kuyilapho ukudluliswa kwe-casein kungafinyelela cishe ku-99%.
Ubuchwepheshe bokuhlukanisa ama-Membrane bunomphumela omuhle we-membrane kanye nomphumela wokuvala inzalo, bungasusa ngokuphelele amagciwane obisini oluwuketshezi, ngesikhathi esifanayo ukunambitheka kobisi nakho kuye kwathuthukiswa.
Ubuchwepheshe bokuhlukanisa ama-membrane ngokuvala inzalo ebandayo yindlela yobisi olusha olushiswe kusengaphambili lufike kuma-degree angama-50 bese ubisi lwe-skim lutholwa ngomshini wokuhlukanisa ukhilimu wobisi.Khona-ke ngosuku olufanayo ubisi lwe-skim olusha lwenza ukuvala inzalo yokuhlunga, kuhlanganiswe nobuchwepheshe bokuvala inzalo obusezingeni eliphezulu obusheshayo, ukuze kufinyelelwe emikhiqizweni yobisi yezinga eliphezulu.Ukuvala inzalo okunezinga lokushisa eliphansi okunjalo kugcina ukunambitheka okuhle nezakhamzimba, iphunga elimnandi.
Ngaphezu kwalokho, ukuhlanza ulwelwesi kulula kakhulu ukuvuselela, ukuze ukungcoliswa kwe-membrane kulawulwe futhi kugcinwe i-membrane flux ephakeme futhi ezinzile.Ukusetshenziswa kobuchwepheshe bokuhlukaniswa kwe-membrane ekwenzeni inzalo ebandayo yobisi, izingxenye ezisebenzayo zingagcinwa ngesikhathi sokuhlukaniswa kabusha komsebenzi, kuyindlela ekahle yokwenza inzalo yobisi.
Ukususwa kwe-Whey Caseim Amagciwane
I-Casein iyisakhi esiyisisekelo se-df ushizi ojwayelekile.Enqubweni yokwenza ushizi, i-casein idonswa yisenzo sama-enzyme e-rennet, futhi kwakhiwa i-coagulum ehlanganisa i-casein, amaprotheni we-whey, amafutha, i-lactose namaminerali obisi.
Ubuchwepheshe bokuhlukanisa i-Membrane busetshenziselwa ukuqeda amagciwane obisi, okusekelwe eqinisweni lokuthi ulwelwesi lunamazinga ahlukene okugcina impahla ezingxenyeni ezihlukahlukene zobisi, kuhlanganise namabhaktheriya nezinhlamvu. ukudluliselwa kungafinyelela cishe ku-99%.
