1. Zida za emulsification Zida zamakina pokonzekera emulsion makamaka ndi emulsifier, yomwe ndi mtundu wa zida za emulsification zomwe zimasakaniza mafuta ndi madzi mofanana. Pakali pano, pali mitundu itatu ikuluikulu ya emulsifiers: emulsification chosakanizira, colloid mphero ndi homogenizer. Mtundu, kapangidwe ndi ntchito ya emulsifier ndi ubale waukulu ndi kukula (dispersibility) wa emulsion particles ndi khalidwe (kukhazikika) kwa emulsion. Nthawi zambiri, monga emulsifier yolimbikitsa yomwe imagwiritsidwabe ntchito kwambiri m'mafakitale odzikongoletsera, emulsion yokonzeka imakhala ndi dispersibility. Tinthu tating'onoting'ono ndi akulu komanso oyipa, osakhazikika, komanso okonda kuipitsidwa. Komabe, kupanga kwake ndikosavuta ndipo mtengo wake ndi wotsika mtengo. Malingana ngati mumasankha makina oyenera ndikugwiritsira ntchito moyenera, amatha kupanga zodzoladzola zodziwika bwino zomwe zimakhala ndi zofunikira zambiri. M'zaka zaposachedwa, Vacuum Mixer Homogenizer mapangidwe apita patsogolo kwambiri, ndipo emulsion yokonzedwa ndi Vacuum Mixer Homogenizer ili ndi dispersibility yabwino komanso kukhazikika.
2. Kutentha Kutentha kwa emulsification kumakhudza kwambiri khalidwe la emulsification, koma palibe malire okhwima pa kutentha. Ngati mafuta ndi madzi zonse zili zamadzimadzi, emulsification imatha kutheka poyambitsa kutentha. Nthawi zambiri, kutentha kwa emulsification kumadalira kusungunuka kwa chinthu chosungunuka kwambiri chomwe chili m'magawo awiriwa, ndikuganiziranso zinthu monga mtundu wa emulsifier ndi kusungunuka kwa gawo la mafuta ndi gawo la madzi. Kuonjezera apo, kutentha kwa magawo awiriwa kuyenera kukhala kofanana, makamaka kwa sera ndi zigawo za mafuta zomwe zimakhala ndi malo osungunuka kwambiri (pamwamba pa 70 ° C), pamene emulsification, gawo la madzi otentha silingawonjezeke kuti muteteze sera, Mafuta amaonekera kunja, zomwe zimapangitsa kuti pakhale ma emulsion a lumpy kapena aukali. Nthawi zambiri, pa emulsification, kutentha kwamafuta ndi madzi kumatha kuyendetsedwa pakati pa 75 ° C ndi 85 ° C. Ngati gawo la mafuta lili ndi sera yosungunuka kwambiri ndi zigawo zina, kutentha kwa emulsification kudzakhala kopambana panthawiyi. Komanso, ngati mamasukidwe akayendedwe ukuwonjezeka kwambiri pa ndondomeko emulsification, otchedwa kwambiri wandiweyani ndi zimakhudza yogwira mtima, kutentha emulsification akhoza moyenerera kuchuluka. Ngati emulsifier ntchito ali ndi ena gawo inversion kutentha, ndi kutentha emulsification ndi bwino anasankha kuzungulira gawo inversion kutentha. The emulsification kutentha komanso nthawi zina zimakhudza tinthu kukula kwa emulsion. Mwachitsanzo, pamene mafuta asidi sopo anionic emulsifier ntchito emulsification ndi njira yaikulu sopo, pamene kutentha emulsification amalamulidwa pa 80 °C, tinthu kukula kwa emulsion ndi za 1.8-2.0 μm. Ngati emulsification ikuchitika pa 60 ° C, kukula kwa tinthu ndi pafupifupi 6 μm. Pamene emulsified ndi nonionic emulsifiers, zotsatira za kutentha emulsification pa tinthu kukula ndi ofooka.
3. Emulsification nthawi yaVacuum Mixer Homogenizerkapangidwe The emulsification nthawi mwachionekere ali ndi chikoka pa khalidwe la emulsion, ndi kutsimikiza kwa nthawi emulsification zachokera voliyumu chiŵerengero cha gawo mafuta ndi gawo madzi, mamasukidwe akayendedwe a magawo awiri ndi mamasukidwe akayendedwe a emulsion chifukwa. , mtundu ndi kuchuluka kwa emulsifier, Palinso kutentha kwa emulsification, koma nthawi ya emulsification ndiyo kupanga dongosolo la emulsifier, lomwe likugwirizana kwambiri. pakuchita bwino kwa zida za emulsification. Nthawi ya emulsification imatha kutsimikiziridwa molingana ndi zomwe zachitika komanso zoyeserera. Ngati homogenizer (3000 rpm) imagwiritsidwa ntchito popanga emulsification, zimangotenga mphindi 3-10.
4. Oyambitsa liwiro Emulsification zida ali ndi chikoka chachikulu pa emulsification, mmodzi wa amene ndi zotsatira za yoyambitsa liwiro pa emulsification. Kuthamanga kwapang'onopang'ono kumakhala kokwanira kuti gawo la mafuta ndi gawo la madzi likhale losakanikirana, ndipo kuthamanga kwachangu ndikwapamwamba kwambiri
5. Kuthamanga liwiro laVacuum Mixer Homogenizer kapangidwe ali ndi chikoka chachikulu pa emulsification, chimodzi mwa izo ndi chikoka cha kusonkhezera liwiro pa emulsification. Kuthamanga kwapang'onopang'ono ndikupangitsa gawo la mafuta ndi gawo lamadzi kukhala losakanikirana. Ngati kuthamanga kwachangu kuli kochepa kwambiri, cholinga cha kusakaniza kwathunthu sichidzatheka. Komabe, ngati liwiro loyendetsa ndilokwera kwambiri, mavuvu a mpweya adzabweretsedwa mu dongosolo, ndikupangitsa kuti ikhale yamagulu atatu. Amapangitsa emulsions kukhala osakhazikika. Chifukwa chake, kulowa kwa mpweya kuyenera kupewedwa panthawi yakugwedezeka, ndipo vacuum emulsifier imakhala ndi ntchito yabwino kwambiri.
Smart Zhitong ali ndi zaka zambiri pakupanga, kupanga Vacuum Mixer HomogenizerChosakaniza cha Homogenizer cha Vacuumndi mphamvu makina kuchokera 5L kuti 18000L
