Emulsifying izixhobo
Isixhobo esiphambili somatshini wokulungiselela i-emulsion ngumatshini we-emulsifying, oluhlobo lwezixhobo ze-emulsifying zokuxuba ioli kunye namanzi ngokulinganayo. Okwangoku, kukho iintlobo ezintathu eziphambili zomatshini wokufaka i-emulsifying: i-emulsifying mixer, i-colloid mill kunye ne-homogenizer. Uhlobo lomatshini we-Emulsifying kunye nesakhiwo, ukusebenza kunye nobukhulu beengqungquthela ze-emulsion (ukusabalalisa) kunye nomgangatho we-emulsion (uzinzo) unobudlelwane obukhulu. Ngokubanzi, njengoko ngoku isetyenziswa ngokubanzi kumzi-mveliso wezithambiso evuselela i-emulsifier, i-emulsion eveliswa kukusasazeka kakubi. Amasuntswana makhulu kwaye arhabaxa, anozinzo olulambathayo kunye nongcoliseko olulula. Kodwa ukuveliswa kwayo kulula, ixabiso liphantsi, nje ukuba unike ingqalelo kwisakhiwo esifanelekileyo somatshini, sebenzisa ngokufanelekileyo, kodwa unokuvelisa iimfuno zomgangatho odibeneyo wezinto zokuthambisa ezidumileyo. I-Colloid Mill kunye ne-homogenizer zizixhobo ezingcono zokumisela. Kwiminyaka yakutshanje, oomatshini be-emulsifying benze inkqubela enkulu, njengomatshini wokucoca i-vacuum, i-emulsion elungiselelwe ukusasazeka kunye nokuzinza kokugqwesileyo.
Ubushushu
Ubushushu be-emulsification bunempembelelo enkulu kwi-emulsification, kodwa akukho mda ongqongqo kwiqondo lokushisa. Ukuba ioli kunye namanzi ziyilwelo, zinokufakwa emulsified ngokuvuselela kwiqondo lokushisa. Ngokuqhelekileyo, ubushushu be-emulsification buxhomekeke kwindawo yokunyibilika kwezinto ezinezinga eliphezulu lokunyibilika kwizigaba ezibini, kunye nezinto ezifana nohlobo lwe-emulsifier kunye ne-solubility yesigaba seoli kunye nesigaba samanzi kufuneka siqwalaselwe. Ukongeza, ubushushu bezigaba ezibini kufuneka bugcinwe phantse bufana, ngakumbi kwinxalenye ye-wax kunye ne-fat phase enendawo yokunyibilika ephezulu (ngaphezulu kwe-70 ℃), xa i-emulsifying, inqanaba lobushushu eliphantsi lamanzi akufanele lifakwe, ukuze thintela i-wax kunye namafutha ukuba angabonakali ngaphandle kwe-emulsification, ekhokelela kwi-emulsion enkulu okanye enqabileyo kunye nokungalingani. Ngokubanzi, xa ufaka i-emulsifying, ubushushu be-oyile kunye namanzi bunokulawulwa phakathi kwe-75℃ kunye ne-85℃. Ukuba isigaba seoli sine-wax ephezulu yokunyibilika kunye nezinye izinto, ukushisa kwe-emulsifying kuya kuba phezulu ngeli xesha. Ukongeza, ukuba i-viscosity iyanda kakhulu kwinkqubo ye-emulsification, ebizwa ngokuba yi-emulsification eninzi kwaye ichaphazela ukuxuba, ubushushu obuthile be-emulsification bunokunyuswa ngokufanelekileyo. Ukuba i-emulsifier esetyenzisiweyo ineqondo elithile lokutshintsha kwesigaba, iqondo lobushushu le-emulsifying likhethwa ngokufanelekileyo malunga neqondo lokutshintsha kwesigaba. Ubushushu be-Emulsification ngamanye amaxesha buchaphazela ubungakanani besuntswana le-emulsion. Ukuba i-anionic emulsifier ye-fatty acid isepha isetyenziswa ngokubanzi, ubungakanani besuntswana le-emulsion bumalunga ne-1.8-2.0μm xa ubushushu be-emulsification bulawulwa kwi-80℃. Ukuba ubungakanani be-particle bumalunga ne-6μm xa i-emulsification iqhutyelwa kwi-60 ℃. Umphumo wobushushu be-emulsification kubungakanani besuntswana bubuthathaka xa i-emulsifier engeyiyo i-ionic isetyenziselwa i-emulsification.
Ixesha lokulinganisa
Ixesha le-Emulsification ngokucacileyo linempembelelo kumgangatho we-emulsion, kwaye ukuzimisela kwexesha lokumisa i-emulsifying kuhambelana nomthamo wesigaba se-oyile yesigaba samanzi, i-viscosity yesigaba sesibini kunye nokuvelisa i-viscosity ye-emulsion, uhlobo kunye ne-dosage ye-emulsifier, i-emulsifying. ubushushu, ixesha emulsifying bangaphi, ngokwaneleyo ukwenza inkqubo emulsification, idityaniswe ngokusondeleyo ukusebenza kakuhle izixhobo emulsification, ixesha Emulsification inokumiselwa ngokungqinelana namava kunye nokulinga. I-Emulsification nge-homogenizer (3000 RPM) ithatha imizuzu eyi-3-10 kuphela.
Ukudibanisa isantya
Izixhobo ze-Emulsification zinempembelelo enkulu kwi-emulsification, enye yazo yimpembelelo yesantya esishukumisayo kwi-emulsification. Isantya esiphakathi kukwenza isigaba se-oyile kunye nesigaba samanzi sixutywe ngokupheleleyo, isantya esisezantsi kakhulu esishukumisayo, ngokucacileyo asinakufezekisa injongo yokuxuba ngokupheleleyo, kodwa isantya esiphezulu kakhulu, siya kuzisa amaqamza kwinkqubo, ukuze ibe yinto emithathu- inkqubo yesigaba, kwaye wenze i-emulsion ingazinzi. Ke ngoko, umoya kufuneka ugwenywe ekuxubeni, kwaye umatshini wokufaka i-vacuum emulsifying unokusebenza okuphezulu kakhulu.
