Nga taputapu whakaemi
Ko nga taputapu miihini matua mo te whakarite i te emulsion ko te miihini emulsifying, he momo taputapu emulsifying mo te whakakotahi i te hinu me te wai.I tenei wa, e toru nga momo matua o te miihini whakakoi: ko te whakaranu whakamere, te mira colloid me te homogenizer.Ko te momo miihini me te hanganga, te mahi me te rahi o nga matūriki whakaehunga (whakamarara) me te kounga o te whakaehunga (te pumau) he hononga nui.Ko te tikanga, penei e whakamahia ana inaianei i roto i te wheketere whakapaipai whakakorikori emulsifier, ko te whakaehunga i puta mai i te mararatanga rawakore.Ko nga matūriki he nui, he kikokore, he ngoikore te pumau me te ngawari o te poke.Engari he maamaa te hanga, he iti noa te utu, mena ka aro koe ki te hanganga tika o te miihini, whakamahia tika, engari ka taea hoki te whakaputa i nga whakaritenga kounga hiato o nga whakapaipai rongonui.Ko te mira Colloid me te homogenizer he pai ake nga taputapu whakaemi.I roto i nga tau tata nei, kua hanga emulsifying mihini nui te ahunga whakamua, pērā i te korehau emulsifying mihini, te whakaehunga rite te marara me te pūmautanga o te pai.
Te pāmahana
He nui te awe o te emulsification pāmahana i runga i te emulsification, engari kahore he rohe tino i runga i te pāmahana.Mena he wai te hinu me te wai, ka taea te whakaehunga ma te whakakorikori i te pāmahana rūma.Ko te tikanga, ko te pāmahana whakaemulsification ka whakawhirinaki ki te ira whakarewa o nga matū he nui te ira whakarewa i roto i nga wahanga e rua, me whakaaro nga mea penei i te momo whakaemulsifier me te whakarewatanga o te wahanga hinu me te wahanga wai.I tua atu, ko te pāmahana o nga waahanga e rua kia rite tonu, ina koa mo nga waahanga wax me nga waahanga ngako me te ira whakarewa teitei (i runga ake i te 70 ℃), i te wa e whakaemi ana, kaua e taapirihia te waahanga wai mahana iti, kia pai ai aukati i te ware pi me te ngako kia kore e maataata i mua i te whakaehunga, ka puta he whakaehunga nui, maataa, koretake hoki.Ko te tikanga, i te wa e whakaemi ana, ka taea te whakahaere i te pāmahana o te hinu me te wai i waenga i te 75 ℃ me te 85 ℃.Mena he nui te wax rewa o te wahanga hinu me etahi atu waahanga, ka nui ake te pāmahana whakaemulsifying i tenei wa.I tua atu, ki te nui haere te pokey i roto i te tukanga emulsification, te mea-ka karanga matotoru rawa, me te pā te ranu, etahi pāmahana whakaemulsification e tika ana te hiki.Mēnā he pāmahana whakawhiti wāhanga te whakaemulsifier e whakamahia ana, he pai rawa te whiriwhiri i te pāmahana whakaemulsifying huri noa i te pāmahana whakawhiti wāhanga.Ko te pāmahana whakaemulsification i etahi wa ka pa ki te rahi matūriki o te whakaehunga.Mena kei te whakamahia te whakaemulsifier anionic o te hopi waikawa ngako, ko te rahi o te matūriki o te whakaehunga e tata ana ki te 1.8-2.0μm ka whakahaeretia te pāmahana whakaemulsification i te 80 ℃.Mena he 6μm te rahi o te matūriki i te wa e whakahaerehia ana te emulsification i te 60 ℃.Ko te painga o te pāmahana whakaemulsification i runga i te rahi matūriki he ngoikore ka whakamahia te emulsifier kore-ionic mo te whakaemulsification.
Te wa whakaehunga
Ko te wa emulsification e tino whai paanga ana ki te kounga o te whakaehunga, a ko te whakatau o te wa emulsifying e rite ana ki te owehenga rōrahi o te wahanga o te wai o te hinu, te rua o nga waahanga me te whakaputa i te pokey o te whakaehunga, te momo me te inenga o te emulsifier, emulsifying. pāmahana, emulsifying wa o te maha, he rawaka ki te hanga i te pūnaha o te emulsification, he tata hono ki te pai o te taputapu emulsification, Emulsification wā e taea te whakatau rite ki te wheako me te whakamātau.Emulsification ki homogenizer (3000 RPM) e 3-10 meneti anake.
Te tere whakaranu
He nui te awe o nga taputapu emulsification i runga i te emulsification, ko tetahi o enei ko te awe o te tere whakaoho i runga i te emulsification.Ko te tere o te whakakorikori kia tino uru te wahanga hinu me te wahanga wai, he iti rawa te tere o te whakakorikori, e kore e taea te whakatutuki i te kaupapa o te whakaranu katoa, engari he nui rawa te tere whakaoho, ka kawe mai nga mirumiru ki roto i te punaha, kia toru- pūnaha wāhanga, me te hanga i te whakaehunga iu.Na reira, me karohia te hau i roto i te whakaranu, me te miihini whakamohoatanga korehau he tino pai te mahi.
