1. Izixhobo ze-Emulsification Isixhobo somatshini wokulungiselela i-emulsion ikakhulu i-emulsifier, luhlobo lwezixhobo ze-emulsification ezixuba ioli kunye namanzi ngokulinganayo. Okwangoku, kukho iintlobo ezintathu eziphambili ze-emulsifiers: i-emulsification mixer, i-colloid mill kunye ne-homogenizer. Uhlobo, ukwakheka kunye nokusebenza kwe-emulsifier kunobudlelwane obukhulu kunye nobukhulu (i-dispersibility) yeengqungquthela ze-emulsion kunye nomgangatho (uzinzo) we-emulsion. Ngokubanzi, njenge-emulsifier eshukumisayo esasetyenziswa kakhulu kwiifektri zokuthambisa, i-emulsion elungisiweyo ayinakuhlakazeka okubi. Amasuntswana makhulu kwaye arhabaxa, azinzanga, kwaye athanda ukungcoliseka. Nangona kunjalo, ukuveliswa kwayo kulula kwaye ixabiso liphantsi. Logama nje ukhetha ulwakhiwo olufanelekileyo lomatshini kwaye ulusebenzise ngokufanelekileyo, lunokuvelisa izithambiso ezidumileyo kunye neemfuno zomgangatho odibeneyo. Kwiminyaka yakutshanje, uyilo lwe-Vacuum Mixer Homogenizer yenze inkqubela phambili enkulu, kwaye i-emulsion elungiselelwe yi-Vacuum Mixer Homogenizer uyilo inokusabalalisa okugqwesileyo kunye nokuzinza.
2. Ubushushu Ubushushu be-emulsification bunempembelelo enkulu kumgangatho we-emulsification, kodwa akukho mda ongqongqo kwiqondo lokushisa. Ukuba i-oyile kunye namanzi zombini ziyi-liquid, i-emulsification inokufezekiswa ngokuvuselela kwiqondo lokushisa. Ngokuqhelekileyo, ubushushu be-emulsification buxhomekeke kwindawo yokunyibilika kwezinto eziphezulu zokunyibilika eziqulethwe kwizigaba ezibini, kwaye ziqwalasela izinto ezifana nohlobo lwe-emulsifier kunye ne-solubility yesigaba seoli kunye nesigaba samanzi. Ukongeza, iqondo lokushisa kwezi zigaba zimbini kufuneka ligcinwe liphantse lifane, ngokukodwa kwi-wax kunye ne-fat phase components kunye neendawo eziphezulu zokunyibilika (ngaphezu kwe-70 ° C), xa i-emulsification, isigaba samanzi esisezantsi asinakongezwa ukuze kuthintelwe. Iwax, Amafutha akhazimla ngaphandle, nto leyo ekhokelela ekubeni ibe namaqhuqhuva okanye arhabaxa, emulsions engalinganiyo. Ngokuqhelekileyo, ngexesha le-emulsification, ubushushu bezigaba ze-oyile kunye namanzi bunokulawulwa phakathi kwe-75 ° C kunye ne-85 ° C. Ukuba isigaba seoli siqulethe i-wax ephezulu yokunyibilika kunye nezinye izinto, ukushisa kwe-emulsification kuya kuba phezulu ngeli xesha. Ukongeza, ukuba i-viscosity iyanda kakhulu ngexesha lenkqubo ye-emulsification, ebizwa ngokuba yi-emulsification eninzi kwaye ichaphazela ukuvuselela, ubushushu be-emulsification bunokwandiswa ngokufanelekileyo. Ukuba i-emulsifier esetyenzisiweyo ineqondo elithile lokuguqulwa kwesigaba, iqondo lobushushu le-emulsification likhethwa ngokufanelekileyo malunga neqondo lokushisa lesigaba. Ubushushu be-emulsification ngamanye amaxesha buba nefuthe kubungakanani besuntswana le-emulsion. Ngokomzekelo, xa i-fatty acid sepha i-anionic emulsifier isetyenziselwa i-emulsification yindlela yokuqala yesepha, xa ukushisa kwe-emulsification kulawulwa kwi-80 ° C, ubukhulu be-particle ye-emulsion malunga ne-1.8-2.0 μm. Ukuba i-emulsification yenziwa kwi-60 ° C, ubukhulu be-particle bu malunga ne-6 μm. Xa i-emulsified kunye ne-nonionic emulsifiers, umphumo wokushisa kwe-emulsification kwi-particle size ibuthathaka.
3. Ixesha lokulinganisaI-vacuum Mixer Homogenizeruyilo Ixesha le-emulsification ngokucacileyo linempembelelo kumgangatho we-emulsion, kwaye ukuzimisela kwexesha le-emulsion lisekelwe kumlinganiselo womthamo wesigaba seoli kunye nesigaba samanzi, i-viscosity yezigaba ezibini kunye ne-viscosity ye-emulsion ebangelwayo. , uhlobo kunye nobungakanani be-emulsifier, Kukho kwakhona ukushisa kwe-emulsification, kodwa ixesha lokulinganisa kukwenza inkqubo i-emulsified ngokupheleleyo, ehambelana ngokusondeleyo nokusebenza kwezixhobo ze-emulsification. Ixesha le-emulsification linokumiselwa ngokwamava kunye nemifuniselo. Ukuba i-homogenizer (3000 rpm) isetyenziselwa i-emulsification, ithatha kuphela i-3-10 imizuzu.
4. Isantya esishukumisayo Isixhobo se-Emulsification sinempembelelo enkulu kwi-emulsification, enye yazo isiphumo sokuvuselela isantya kwi-emulsification. Isantya esichukumisayo siphakathi ukwenza isigaba seoli kunye nesigaba samanzi sixutywe ngokupheleleyo, kwaye isantya esichukumisayo siphezulu kakhulu
5. Isantya esishukumisayo seI-vacuum Mixer Homogenizer uyilo lunempembelelo enkulu kwi-emulsification, enye yazo yimpembelelo yesantya esishukumisayo kwi-emulsification. Isantya esiphakathi esishukumisayo kukwenza isigaba seoli kunye nesigaba samanzi sixutywe ngokupheleleyo. Ukuba isantya sokuvuselela siphantsi kakhulu, injongo yokuxuba ngokupheleleyo ayiyi kufezekiswa ngokucacileyo. Nangona kunjalo, ukuba isantya esishukumisayo siphezulu kakhulu, amaqamza omoya aya kuziswa kwinkqubo, okwenza inkqubo yezigaba ezintathu. Yenza i-emulsions ingazinzi. Ke ngoko, ukungena komoya kufuneka kugwenywe ngexesha lokuvuselela, kwaye i-vacuum emulsifier inokusebenza okuhle kakhulu.
