Zinthu zomwe zimakhudza emulsification

Emulsifying zida

Waukulu makina zida pokonzekera emulsion ndi emulsifying makina, amene ndi mtundu wa zida emulsifying kusakaniza mafuta ndi madzi wogawana. Pakali pano, pali mitundu itatu ikuluikulu ya makina emulsifying: emulsifying chosakanizira, colloid mphero ndi homogenizer. Emulsifying makina mtundu ndi dongosolo, ntchito ndi kukula kwa emulsion particles (kubalalitsidwa) ndi khalidwe la emulsion (bata) ali ndi ubale waukulu. Nthawi zambiri, monga tsopano chimagwiritsidwa ntchito mu zodzoladzola fakitale yogwira mtima emulsifier, ndi emulsion opangidwa ndi kubalalitsidwa osauka. Tinthu tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ting'onoting'ono. Koma kupanga kwake n'kosavuta, mtengo wake ndi wotchipa, malinga ngati mumayang'anitsitsa kapangidwe kake ka makina, gwiritsani ntchito bwino, komanso mukhoza kupanga zofunikira zambiri zamtundu wa zodzoladzola zotchuka. Colloid mphero ndi homogenizer ndi bwino emulsifying zida. M'zaka zaposachedwapa, emulsifying makina wapita patsogolo kwambiri, monga zingalowe emulsifying makina, ndi emulsion wokonzeka ndi kubalalitsidwa ndi bata wabwino kwambiri.

Kutentha

Kutentha kwa emulsification kumakhudza kwambiri emulsification, koma palibe malire okhwima pa kutentha. Ngati mafuta ndi madzi ndi madzi, akhoza emulsified ndi kusonkhezera kutentha firiji. Nthawi zambiri, kutentha kwa emulsification kumadalira malo osungunuka a zinthu zomwe zimakhala ndi malo osungunuka kwambiri m'magawo awiri, ndipo zinthu monga mtundu wa emulsifier ndi kusungunuka kwa gawo la mafuta ndi gawo la madzi ziyenera kuganiziridwa. Kuphatikiza apo, kutentha kwa magawo awiriwa kuyenera kukhala kofanana, makamaka kwa sera ndi zigawo zamafuta zomwe zimakhala ndi malo osungunuka kwambiri (pamwamba pa 70 ℃), popanga emulsifying, gawo lamadzi lotsika siliyenera kuwonjezeredwa, kuletsa sera ndi mafuta kuti crystallizing kunja pamaso emulsification, kumabweretsa waukulu kapena coarse ndi m'goli emulsion. Nthawi zambiri, pamene emulsifying, kutentha kwa mafuta ndi madzi akhoza kulamulidwa pakati pa 75 ℃ ndi 85 ℃. Ngati mafuta gawo ali mkulu kusungunuka mfundo sera ndi zigawo zina, kutentha emulsifying adzakhala apamwamba pa nthawi ino. Komanso, ngati mamasukidwe akayendedwe ukuwonjezeka kwambiri mu ndondomeko emulsification, otchedwa kwambiri wandiweyani ndi zimakhudza kusanganikirana, ena emulsification kutentha akhoza moyenerera anaukitsidwa. Ngati emulsifier wogwiritsidwa ntchito ali ndi kutentha kwa gawo linalake, kutentha kwa emulsifying kumasankhidwanso mozungulira kutentha kwa gawo. Emulsification kutentha nthawi zina kumakhudzanso tinthu kukula kwa emulsion. Ngati anionic emulsifier wa mafuta asidi sopo zambiri ntchito, tinthu kukula emulsion ndi za 1.8-2.0μm pamene kutentha emulsification umalamulidwa pa 80 ℃. Ngati tinthu kukula ndi za 6μm pamene emulsification ikuchitika pa 60 ℃. Zotsatira za kutentha kwa emulsification pa kukula kwa tinthu ndizofooka pamene emulsifier yosakhala ionic imagwiritsidwa ntchito pa emulsification.

Emulsifying nthawi

Emulsification nthawi mwachionekere zimakhudza khalidwe la emulsion, ndi kutsimikiza kwa nthawi emulsifying malinga ndi voliyumu chiŵerengero cha gawo mafuta gawo madzi, awiri gawo mamasukidwe akayendedwe ndi kupanga mamasukidwe akayendedwe a emulsion, mtundu ndi mlingo wa emulsifier, emulsifying. kutentha, emulsifying nthawi angati, ndi yokwanira kuti dongosolo emulsification, limagwirizana kwambiri ndi dzuwa la zida emulsification, Emulsification nthawi angadziŵike malinga ndi zinachitikira ndi kuyesera. Emulsification ndi homogenizer (3000 RPM) imatenga mphindi 3-10 zokha.

Kusakaniza liwiro

Emulsification zida ali ndi chikoka chachikulu pa emulsification, mmodzi wa amene ndi chikoka choyambitsa liwiro pa emulsification. Zolimbitsa yogwira mtima liwiro ndi kupanga mafuta gawo ndi madzi gawo mokwanira osakaniza, otsika kwambiri yogwira mtima liwiro, mwachionekere sangathe kukwaniritsa cholinga cha kusanganikirana zonse, koma mkulu kwambiri yogwira mtima liwiro, adzabweretsa thovu mu dongosolo, kotero kuti amakhala atatu- gawo, ndikupanga emulsion kukhala yosakhazikika. Chifukwa chake, mpweya uyenera kupewedwa pakusakanikirana, ndipo makina opangira vacuum emulsifying ali ndi magwiridwe antchito apamwamba kwambiri.
