Inkqubo yokucoca i-oyile etyiwayo: i-water Degumming
Ingcaciso yeMveliso
Inkqubo yokucoca ioyile kwisityalo sokusulungekisa ioyile kukususa ukungcola kwentsini kwioyile ekrwada ngeendlela zomzimba okanye zekhemikhali, kwaye linqanaba lokuqala lokusulungekiswa kweoyile / inkqubo yokucoca.Emva kokucofa ngokucofa kunye nokutsalwa kwe-solvent kwi-oilseeds, i-oyile ekrwada iqulathe ikakhulu i-triglycerides kunye nee-non-triglyceride ezimbalwa.Ukubunjwa kwe-non-triglyceride kuquka i-phospholipids, iiprotheni, i-phlegmatic kunye noshukela kuya kusabela kunye ne-triglycerides ukwenza i-colloid, eyaziwa ngokuba yi-gum ukungcola.
Ukungcola kwegum akuchaphazeli nje kuphela ukuzinza kweoli kodwa kuchaphazela umphumo wenkqubo yokucoca ioli kunye nokucubungula okunzulu.Ngokomzekelo, ioli e-non-degummed kulula ukwenza ioli e-emulsified kwinkqubo yokucoca i-alkaline, ngaloo ndlela yandisa ubunzima bokusebenza, ilahleko yokucocwa kweoli, kunye nokusetyenziswa kwezinto ezincedisayo;kwinkqubo ye-decolorization, i-oyile e-non-degummed iya kwandisa ukusetyenziswa kwe-adsorbent kunye nokunciphisa ukusebenza kwe-discoloring.Ke ngoko, ukususwa kwetshungama kuyimfuneko njengenyathelo lokuqala kwinkqubo yokucoca ioyile phambi kokuba i-oyile idecicide, i-oyile decolorization, kunye ne-oyile yokuvumba.
Iindlela ezithile ze-degumming ziquka i-hydrated degumming (i-water degumming), i-asidi yokucoca i-degumming, indlela yokucoca i-alkali, indlela ye-adsorption, i-electropolymerization kunye ne-thermal polymerization method.Kwinkqubo yokucoca ioli edliwayo, eyona ndlela isetyenziswa ngokuqhelekileyo i-hydrated degumming, enokuthi ikhuphe i-phospholipids e-hydratable kunye nezinye i-phospholipids ezingenayo i-hydrate, ngelixa i-phospholipids eseleyo engekho-hydrate kufuneka isuswe nge-acid refining degumming.
1. Umgaqo osebenzayo we-hydrated degumming (i-water degumming)
I-oyile ekrwada evela kwinkqubo yokukhutshwa kwe-solvent iqulethe amacandelo e-soluble yamanzi, ngokuyinhloko aqulethwe i-phospholipids, efuna ukususwa kwioli ukwenzela ukuba imvula encinci ivule kwaye ihlale ngexesha lokuthuthwa kweoli kunye nokugcinwa kwexesha elide.Ukungcola kweentsini ezifana ne-phospholipids kunempawu ye-hydrophilic.Okokuqala, ungashukumisa kwaye wongeze isixa esithile samanzi ashushu okanye isisombululo se-electrolyte aqueous njengetyuwa kunye ne-phosphoric acid kwi-oyile ekrwada eshushu.Emva kwexesha elithile lokusabela, ukungcola kweentsini kuya kuthungwa, kuthotywe kwaye kususwe kwioli.Kwinkqubo ye-hydrated degumming, ukungcola ikakhulu yi-phospholipid, kunye neeprotheni ezimbalwa, i-glyceryl diglyceride, kunye ne-mucilage.Ngaphezu koko, iintsini ezikhutshiweyo zinokulungiswa zibe yi-lecithin yokutya, ukutya kwezilwanyana okanye ukusetyenziswa kobugcisa.
2. Inkqubo ye-hydrated degumming (i-water degumming)
Inkqubo yokucoca amanzi ibandakanya ukongeza amanzi kwi-oyile ekrwada, ukufakela amanzi kwizixhobo ezinyibilikayo emanzini, emva koko kususwe uninzi lwazo ngokwahlukana kwe-centrifugal.Isigaba sokukhanya emva kokuhlukana kwe-centrifugal yi-oyile ye-degummed ekrwada, kwaye isigaba esinzima emva kokuhlukana kwe-centrifugal yindibaniselwano yamanzi, izakhi ezinyibilikayo emanzini kunye ne-oyile edibeneyo, ngokudibeneyo ebizwa ngokuba "iintsini".I-oyile ekrwada ye-degummed yomiswa kwaye ipholiswe phambi kokuba ithunyelwe kwindawo yokugcina.Iintsini ziphindiselwa ekutyeni.
Kwiplanti yokusulungekisa ioyile, umatshini we-hydrated degumming unokusetyenzwa kunye nomatshini wokuphelisa i-oyile, umatshini wokuthambisa i-oyile, kunye noomatshini bokucoca ioyile, kwaye aba matshini baludidi lwemveliso yokucoca ioyile.Umgca wokucoca uhlelwe ngohlobo oluphakathi, uhlobo oluqhubekayo, kunye nohlobo oluqhubekayo ngokupheleleyo.Umthengi unokukhetha uhlobo ngokuhambelana nomthamo wabo wemveliso efunekayo: umzi-mveliso onamandla okuvelisa i-1-10t ngosuku ufanelekile ukusebenzisa izixhobo zohlobo oluphakathi, i-20-50t ngosuku lwemveliso ilungele ukusebenzisa izixhobo zohlobo oluqhubekayo, ukuvelisa. ngaphezu kwe-50t ngosuku ilungele ukusetyenziswa kohlobo lwezixhobo eziqhubekayo ngokupheleleyo.Olona hlobo lusetyenziswa ngokuqhelekileyo yilayini yemveliso ye-hydrated degumming.
IParameter yobuGcisa
Ezona zinto ziphambili zeHydrated degumming (i-water degumming)
3.1 Umthamo wamanzi awongeziweyo
(1) Isiphumo samanzi ongezelelweyo kwi-flocculation: Ubungakanani obufanelekileyo bamanzi bunokwenza i-stable multi-layer liposome structure.Ukungonelanga kwamanzi kuya kukhokelela kumanzi angaphelelanga kunye ne-colloidal flocculation embi;Amanzi amaninzi athambekele ekwenzeni i-emulsification ye-oyile yamanzi, enzima ukwahlula ukungcola kwioli.
(2) Ubudlelwane phakathi kwesiqulatho samanzi esongeziweyo (W) kunye nomxholo wegluum (G) kubushushu obuhlukeneyo bokusebenza:
| ubushushu obuphantsi bokumanzisa (20 ~ 30℃) | W=(0)5~1)G |
| ubushushu obuphakathi (60~65℃) | W=(2~3)G |
| ubushushu obuphezulu behydration (85 ~ 95℃) | W=(3~3.5)G |
(3) Uvavanyo lwesampula: Ubungakanani obufanelekileyo bamanzi abongeziweyo bunokumiselwa ngovavanyo lwesampulu.
3.2 Ubushushu bokusebenza
Ubushushu bokusebenza buqhelekile buhambelana nobushushu obubalulekileyo (ukwenza ngcono i-flocculation, ubushushu bokusebenza bunokuba ngaphezulu kancinci kunobushushu obubalulekileyo).Kwaye ubushushu bokusebenza buyakuchaphazela ubungakanani bamanzi ongezelelweyo xa izinga lokushisa liphezulu, inani lamanzi likhulu, ngaphandle koko, lincinci.
3.3 Ubunzulu bomxube we-hydration kunye nexesha lokuphendula
(1) I-Inhomogeneous hydration: I-Gum flocculation yi-heterogeneous reaction kwi-interface yentsebenziswano.Ukuze wenze i-emulsion state e-oil-water emulsion state, ukuxuba ngomatshini umxube unokwenza amaconsi ahlakazeke ngokupheleleyo, ukuxubana ngomatshini kufuneka kuqiniswe ngakumbi xa inani lamanzi elongezelelweyo likhulu kwaye ubushushu buphantsi.
(2) Ukunyaniseka kwe-hydration mixing: Xa udibanisa ioli ngamanzi, isantya esishukumisayo si-60 r / min.Ngexesha lokuvelisa i-flocculation, isantya esishukumisayo si-30 r / min.Ixesha lokuphendula lokuxutywa kwe-hydration lijikeleze imizuzu engama-30.
3.4 Ii-Electrolytes
(1) Iindidi ze-electrolytes: Ityuwa, i-alum, i-sodium silicate, i-phosphoric acid, i-citric acid kunye ne-dilute sodium hydroxide solution.
(2) Umsebenzi ongundoqo we-electrolyte:
a.I-Electrolytes inokunciphisa enye intlawulo yombane ye-colloidal particles kwaye ikhuthaze i-colloidal particles to sedimentate.
b.Ukuguqula i-phospholipids engekho-hydrated kwi-hydrated phospholipids.
c.Alum: flocculant uncedo.I-alum inokufunxa i-pigments kwi-oyile.
d.Ukutshiza ngeeoni zetsimbi kwaye uzisuse.
e.Ukukhuthaza i-colloidal flocculation ngokusondeleyo kunye nokunciphisa umxholo weoli kwiiflocs.
3.5 Eminye imiba
(1) Ukufana kwe-oyile: Ngaphambi kokufakwa kwamanzi, i-oyile ekrwada kufuneka ixutywe ngokupheleleyo ukuze i-colloid isasazwe ngokulinganayo.
(2) iqondo lobushushu lamanzi adityanisiweyo: Xa kufakwa amanzi, ubushushu bokongeza amanzi bufanele bulingane okanye buphakame kancinane kunobushushu be-oyile.
(3) Umgangatho wamanzi ongezelelweyo
(4) Uzinzo lokusebenza
Ngokuqhelekileyo, iiparitha zobugcisa benkqubo ye-degumming zichongwa ngokuhambelana nomgangatho weoli, kwaye iiparitha zeeoli ezahlukeneyo kwinkqubo yokukhupha i-degumming ziyahluka.Ukuba unomdla wokucoca ioli, nceda uqhagamshelane nathi ngemibuzo okanye imibono yakho.Siza kulungiselela iinjineli zethu zobuchwephesha ukwenza ngokwezifiso umgca we-oyile ofanelekileyo oxhotyiswe ngezixhobo ezihambelanayo zokusulungekisa ioyile yakho.
